9/9     Looking to buy an entry-level telescope in the ~$500 range.
        Any recommendations?
        \_ I have a Meade ETX-90 (the old non-computerized version).
           Excellent optics and very portable.
               http://www.meade.com/catalog/etx/etx_mak.html
           Or if you like Celestrons, this isn't too bad -- wider aperture
           but a bit bulkier:
               http://csua.org/u/dc2
           At any rate, go for as large an aperture as you can afford.
           -geordan
           \_ second that.  It's not the size, it's the apature that matters.
        \_ I have a Celestron mirror telescope with a 910mm lens.  It's
           great for starting.  Look at http://www.scopereviews.com for some info,
           but there are many other great sites you'll find with some basic
           googling.  It's not strictly "entry-level", but I would look for
           a scope that can fit a motor with usb controller port--it's great
           to be able to just point and click on objects on some planetarium
           program on a laptop and have the scope move there, as well as to
           have it keep tracking an object.  A Russian colleague who's teh
           telescope god recommended some Russian outfit that makes super high
           quality scopes for far less than Meade or Takahashi; I can find out
           if you're interested.  Most important:  get a really good bag for
           it so you can go into the field.  -John
           \_ John, you have too many expensive hobbies.
              By the way, are those big and cheap reflectors any good
              for beginners?
              \_ Urgh, it was a present from my girlfriend.  This one wasn't
                 "cheap" per se (about $1.5k, but relatively inexpensive as
                 far as good telescopes go--remember that, like cameras, sky's
                 the limit pricewise.)  Depends on what you mean by "good"--I
                 took some time to read up on lenses, cosmic objects, whatnot,
                 but I still just like going out and looking at Jupiter/Mars.
                 It's sort of important how much you intend to get into the
                 topic.  Maybe it's best to find someone knowledgeable to go
                 stargazing with--people with good telescopes are usually
                 pretty enthusiastic about getting people into it.  I'd ask
                 Prof. Filipenko (sp?) about some pointers, if he's still
                 around.  -John
                 \_ why would you ask Filipenko about a hobby telescope?
                 \_ Why would you ask Filipenko about a hobby telescope?
                    Do you ask Econ profs for tax/investment/real estate
                    advice?
                    \_ Are you being difficult on purpose?  I'm trying to be
                       informative.  Filipenko might know about clubs of
                       hobby astronomers in the BA who will probably be
                       happy to help you/op get into it--he seemed pretty
                       approachable about stuff like that.  Also, I just
                       remembered that I lived next to a guy in SF who was
                       part of a club that ground their own lenses and sold
                       really nice home-made telescopes--if you ask around,
                       maybe you can get a good deal on one of those.  -John
                    \_ Why wouldn't you ask an econ prof for that sort of
                       advice? Most econ profs I met were pretty well off
                       financially. It's their expertise. Likewise, asking
                       astronomers about telescopes makes a lot of sense.
                       What's your deal?
                       \- it make a lot more sense to ask a hobbyist group
                          in the telescope case. do you ask cs profs what
                          computer you should buy? dear prof katz, which
                          raid card do you recommend. econ profs may have
                          perfectly good answers but unless you have a
                          non-standard relationship with them, i dont think
                          it would be appropriate to make an appt with one
                          to talk about your portfolio. unless filipenko in
                          particular has somehow advertised "come talk to
                          me if you are interested in buying a telescope".
                          \_ I think if you're in his class it is perfectly
                             reasonable to ask him. I'm not discussing
                             the case where one makes a totally random
                             appointment with a prof they do not know. Maybe
                             a hobbyist group would give better answers.
                             Maybe not. I found astronomy profs at
                             Berkeley to be fantastically approachable in
                             addition to extremely bright. My astronomy
                             profs were some of the only profs I had at
                             Berkeley that gave the impression they loved
                             to teach and actually cared about students.

        Malasia to put man on the moon by 2020, with a budget of 25m.
        Eh, ok. Whatever. Are they high on opium?
        \_ I can put several men on the moon by 2020 for significantly
           less than that.  Note that, like the article, I didn't say
           anything about "alive" or "round trip".  -John
        \_ I guess they didn't mention anything about bring man back
           *FROM* the moon :p
        \_ I think they can do it if they relax some of the constraints,
           like getting the astronaut there alive.
           \_ They must have found a free rocket somewhere, because $25M
              won't even get the corpse of an astronaut there.
           \_ You don't get the dead body back either

8/10    What's the difference between P(A,B), P(A,B=true), P(A=true,B=true) and
        P(A|B)?  I'm trying to follow the ID thread below.  Thx.
        \_ P(A,B) is a table, with an entry for each possible value combinations
           of A and B.  The numbers in the table have to sum up to 1.  Each
           entry in the table corresponds to the probability of A and B
           attaining the indexing values.  P(A=true,B=true) is a number, the
           probability that both events happened.  P(A,B=true) is a table
           where each corresponds to some value of A, and means 'probability
           that A takes on that value and B is true.' P(A|B) = P(A,B)/P(B)
           where you divide consistent entries.  P(A|B) is a table with an
           entry for each possible combination of values of A and B, where the
           entry means 'the probability A attains the given indexing value
           given that the given indexing value of B was observed.'
           For now you can ignore what happens if A or B range over
           reals (or take some measure theory). -- ilyas

              \_ I was disappointed that the thread got stuck on the argument
                 over observational bias, but never questioned the underlying
                 assumption that an alteration in the universal constants
                 would have precluded life.  Life is a powerful phenominon,
                 and there are (at least) two independent instances of it on
                 Earth alone.  (e.g. The oxygen based life covering most of
                 the earth and oceans, plus the ferric/ferrous based life
                 found in the heat vents around Seven Mile Trench and
                 lots of mines and a river in Spain) -mel
                 \_ I was assuming life cannot arise without powerful energy
                    sources like stars which an alteration of constants would
                    likely not produce.   Why did I assume this?  Because
                    life is a 'low entropy' process, and such a process needs
                    a lot of energy coming down to maintain itself.
                    These 'two independent instances'
                    aren't really independent (they arose from a common
                    ancestor) they just use a different metabolic mechanism.
                    Many other metabolism types were used at various points
                    in Earth's life. -- ilyas

                    \_ My mistake in calling the ferrooxindans independent.
                       Obviously since they have DNA and a biological cell,
                       there is a common ancestor involved.  A better point I
                       should have made regarding them is that most people
                       would have trouble imagining life existing without
                       oxygen, but these bacteria do that just fine.  I
                       doubt that life in a more generic sense has all
                       that strict a set of requirements on what environmental
                       conditions under which SOMETHING will evolve. -mel

                    \- hello, it is true that is if you tweak certain numbers
                       you cannot have even matter [like without CP violation
                       you cannot explain why we dont have a lot of anti-
                       matter hanging around], while tweaking yet other
                       numbers would not allow nuclei to form, this would
                       would live in a soup of only elementary particles
                       (although possibly some rarely seen ones like the
                       OMEGA- made from SSS). However, there are some
                       free parameters which if tweaked slightly IN ISOLATION
                       we still could get a pretty similar universe in terms
                       of large structure. However it is possible something
                       like the water molecule would not exist. Water is not
                       important to cosmology but it is obviously important
                       to LIFE. If something like the FERMI CONSTANT were
                       different it would change the energy of the fundemantal
                       reactions in the stars which would in turn change their
                       geometry and power spectrum ... so again large con-
                       sequences for "life" and our solar system, but at
                       the large scale and with a "non-antropic eye" the
                       universe may not be too different [there is actually
                       more to the Fermi value, but that is beyond the scope
                       of this discussion]. One may also wish to explore
                       what is the fundamental cause of the PAULI EXCLUSION
                       PRINCIPLE of FERMIONS which allows for elements and
                       chemistry to exist via the AUFBAU PROCESS (I am not

                       \_ Water is very important to life on Earth, but
                          in a universe where water didn't exist, there
                          is little reason to believe that no other

                          Pauli Exclusion or Conservation of Energy is
                          outside the scope of what interests me.  As

                          to me is what the minimal set of requirements
                          are to generate an evolutionary system. -mel

                                   10% closer to the sun or had a greater
                                   tilt or weaker van allen belt etc may be
                                   perfectly interesting but those are not
                                   really cases of "the laws of physics being
                                   different" or "the nature of the universe
                                   being different" ... those are accidental
                                   details in a way things like the CKM matrix
                                   coefficients are not. when you are talking
                                   about something like the standard model,
                                   "emergent phenomena" is things like stars

           go?
           \_ networks can go down, they have multiple points of failure
              - what do you do then?
              \_ I see.
        \_ NASA is intentionally slow to adopt new technology for use on
           the orbiters.  In addition to testing the living hell out of
           particular systems themselves, they also want the general
           technology to have seen widespread use enough to have flushed
           out any problems.  Note that other thread in the motd at the
           moment about motherboards with bad capacitors, and consider that
           it's probably a good thing that the orbiters' avionics are ugraded
           less frequently than the average sodan's computer.  Remember that
           the shuttle program started in the seventies, and that floppies
           actually represent an *upgrade*.  For the poster who asked why
           anything is on removable media, what else would you suggest?
           Hard drives don't perform well under a lot of acceleration, and
           can be damaged easily by vibration (such as during launch and
           reentry).  Many nonvolatile memory technologies have come and gone
           over the life of the shuttle program without being adopted.  When
           they started, the computers available simply didn't have enough
           memory and they had to load things in from tapes over the course
           of a mission.  In a system as complex as the shuttle, there's
           a tremendous ripple effect to changing the flight computers, both
           to the physical systems and the procedures and training for all
           personnel involved.  Given the risks, there's a lot to be said for
           not fixing it if that aspect of the shuttle isn't broken.

           shown that the shuttle can re-enter without the gap filler).  -tom

           either.
           \_ Of course I don't.  That's why I'm asking.
           \_ Don't forget that the airframe expands and contracts much more
              than the tiles.  The tiles are attached to the airframe.
              Therefore, you need gaps between the tiles.  What goes in
              between the gaps.  Gap filluhs!
              \_ We need gaps, then we need gap fillers to eliminate the gaps.
                 Hmmm ...... :-)
                 \_ You mean we have a gap-filler gap?

7/25    It's been pretty hot lately and I had this crazy idea to make a
        living quarter cooler without using a lot of electricity. Some
        properties have fountains or swimming pools. How about repiping them
        with a pump so that they'd flow from the roof (like a building
        that is always being rained on) to cool the entire building?
        It'll use some water, but I'm sure it's a lot cheaper than AC.
        \_ A good idea, and not a new one.
           \_ URL please?
              \_ Google for "swamp cooler"
              \_ Google^H^H^H^H^H^HYahoo! for "swamp cooler"
                 \_ How the hell do you feel cool when you're swamped with
                    high humidity? It's just oxymoron.
        \_ The best system is probably very good insulation, reflective/white
           buildings with control of indoor sunshine, opening up to cool
           at night, and possibly some floor-based cooling.
           \_ Most ordinary houses have windows that can be opened to cool at
              night before you go to sleep.  I do that to keep my house not
              as hot during daytime for my parent.
        \_ I have another idea.  Buy a lot of blue ice, or fill up a lot of
           used bottles with water or whatever that has a high specific heat
           capacity.  Put them on a big cart.  Push it out to the backyard in
           the evening.  Push it back indoor in the morning and blow on it with
           a small fan.  It won't work as well as AC, but it's more
           enviromentally friendly and costs less.  If using bottles, lots of
           small bottles will work better than big 5-gallon ones.

           is involved in growing, preparing, transporting, and storing the

                                      rescue, it _still_ does not necessarily
                                      imply we ought to drastically reduce
                                      green house gas emissions.  This is
                                      simply because we are cutting into
                                      industrial and economic development,
                                      which may lead to a better solution
                                      to the problem.  This is similar to the

                                      problem.  I would be curious to hear

                                      would be (if they were king of the

7/8     Cut global warming by becoming vegetarian:

        \_ Cut global warming with eco-friendly investments:
           http://www.terrapass.com
           \_ How does one know that the money we pay on purchasing these
              passes actually goes to projects that reduce pollution, and these
              projects actually have big enough of an impact to offset our
              cars' pollutant output?
              \_ Good question, and I don't have a good answer. I suppose you
                 could argue that you have a contract with them, so they're
                 obligated to follow-through.
        \_ Cut global warming by turning off the water when you apply soap in
           the middle of a shower.  This saves water as well as the energy
           needed to heat it.
           \_ Not eating 1 pound of western beef saves more water than not
              showering for 1 year, assuming 7 minute showers once per day
              with a low flow shower head.  "Raising one cow uses enough
              water to float a destroyer"
              \_ Just shooting yourself as soon as possible saves more water
                 and energy and cute little bacteria that you'd otherwise
                 spend your life stompin' on than you can possibly imagine.
                 I'll take mine medium rare, thanks.  -John
              \_ Uh, this is really poorly phrased.  Not eating 1 pound of
                 beef doesn't save anything.  That cow is still raised.
                 \_ Have you ever heard of supply & demand?  Buying and
                    tossing one pound of beef doesn't do anything, true.
                    However, choosing to purchase less beef directly affects
                    demand, which will in turn affect supply.
              \_ Are you serious???  Reference please?  Thx.
                 \_ John Robbins Food Revolution, which had extensive
                    footnotes in that section.  Note that it takes a lot
                    more water to raise cattle in the arid west, which is
                    why I said *western beef*.  Here is a webpage that
                    discusses the topic (took me about 5 seconds with google):
                    http://www.vegsource.com/articles/pimentel_water.htm
                    Another one:
                      http://www.gentleworld.org/environment/environment.html
                    Oh look more:
                    http://www.farnellfamily.com/cfarnell/why/uses.html
                    Note that producing beef in arid climates takes more
                    than 2500 gallons/pound.
              \_ Don't eat fruits either. Raising one plum tree uses
                 enough water to float a destroyer. We should eat only
                 cactus.
                 \_ Whatever
                    \_ Whatever indeed. Focus on one aspect of farming
                       (cattle) and ignore the rest.
                       \_ I think the pp was focusing on the fact that
                          raising 1 pound of meat consumes a lot more
                          water than raising 1 pound of fruit/vegetable:
                          http://www.vegsource.com/articles/factoids.htm
                          \_ Ah yes this is the exact reference
                       \_ The issue is not whether farming uses water.
                          Raising beef just uses orders of magnitude more
                          water for the same nutrional content.  So one
                          water for the same nutritional content.  So one
                          way to be environmental is not to eat beef, simple.
                          \_ Right. Another way is to eat only cactus and
                             not water-loving plants like rice and fruit.
                             Or, like John said, shoot yourself.
                             \_ can you be more disengenous? from the above
                                link: water req'd for 1 lb. of apples: 49
                                that's two orders of magnitude
                                less than the amt. req'd for beef.  Eating
                                cactus vs. apples counts for nothing compared
                                to the simple act of not eating beef. -!pp, !op
                                \_ How much protein is in those apples?
                                   If you want to grow, say, soy beans
                                   it take 250 gallons per pound. I find
                                   all of these sorts of arguments
                                   disingenuous. Eat healthy. That means
                                   some meat (but not a lot) in the diet.
                                   Avoiding 1 lb of beef per week (say)
                                   to substitute with 1 lb of apples is
                                   beyond stupid. There are other factors,
                                   too, like cooking, transportation (beef
                                   needs freezing), pesticides, and so on.
                                   Framing in terms of gallons/pound is
                                   meaningless and idiotic.
                                   \_ No it's not, it tells us how much water
                                      beef takes.  It also takes more of many
                                      other resources such as fuel and space.
                                      Why is disingenuous to look at the amount
                                      of resources a certain diet takes?  Meat
                                      eating simply uses way more resources.
                                      Now whether or not that matters to you
                                      is a different issue, isn't it?
                                      \_ The point here is that water
                                         usage is not defined in a vacuum.
                                         Looking at how much water a cow
                                         drinks versus how much water a tree
                                         needs is not too informative in
                                         itself. So much more is involved in
                                         growing, preparing, transporting,
                                         and storing the foods. Is that
                                         gallons/pound number derived by adding
                                         in how many gallons it takes to grow
                                         feed or is it just what the cow
                                         drinks? How much of that water is
                                         taken of the water cycle and in what
                                         way? What other factors are involved?
                                   \_ strawman. What you find disingenuous is
                                      not a claim anyone made.  It's idiotic
                                      to replace one lb. of beef w/ one lb. of
                                      apples.  The gallons/apple was made to
                                      refute above trolls nonsense about fruit
                                      trees.
                                      \_ What do you mean? If you don't eat
                                           fruit you can save a lot of water.
                                   \_ Then replace one pound of beef with
                                      beans, or whatever combination of
                                        non-MEAT vegetables/fruits diet you
                                           desire.  None of them will use as
                                           much water to create the same
                                      desire.  None of them will use remotely
                                      as much water to create the same
                                      nutrition, and you know that.
                                      \_ I am not sure 'energy' = 'nutrition'.
                                         Maybe if we were herbivores it would
                                         make more sense. There are indeed
                                         lots of drawbacks to farming, fishing,
                                         and so on. Looking at water use is
                                         some sort of feel-good bullshit.
                                         I can say it takes no (fresh) water to
                                         raise a tuna. Therefore eat only
                                         tuna and no apples.
                      \_  Don't forget all the water that is required to
                          maintain a healthy green lawn that no one ever
                          uses.

                             The average lawn uses 125 g/1000 sq. ft on a hot,
                             summer day.  That's .8 oz. of beef/1000 sq. ft
                             during peak summer weather. Certainly, it helps
                             to reduce lawn watering, but compared to eating
                             beef, it's peanuts.

                \_ When the other side can come up only with pedantic crap,
                   that's a safe bet you've won the argument.
        \_ So saying "you should avoid X to conserve Y" is a poor long-term
           plan: if water is actually a scarce resource, it should be expensive,
           and thus the beef should be expensive.  If there's some reason it
           isn't (government subsidies, perhaps?), the subsidies should end.
           There's no reason the free market can't solve this problem... if
           there is one.  If there isn't, who cares how "wasteful" meat
           production is?  People aren't starving in the world because the US
           doesn't produce enough food.

5/31    \_ Um.  The central claim that life cannot arise by a blind process is
           falsifiable.  If Darwinists succeed in creating a plausible (or
           better yet, reproducible) story for life's creation that will
           falsify the claim.  The argument that something that doesn't make
           experimentally falsifiable claims is not science is extremely weak.
           It's certainly true, but many things that aren't science make
           falsifiable claims.  -- ilyas
           \_ Is it really ilyas?  I mean, it may be theoretically, but not
              practically.  I maintain my assertion that ID has not produced
              any prediction that can be tested.  Since you've not produced a
              definition of what "life" constitutes, your "falsifiable"
              prediction can't actually be tested (though you seem to believe
              that RNA alone isn't "life").  -emarkp
              \_ I don't really understand.  If someone creates a bacterium
                 in a tube using a 'mechanical process' that would falsify
                 the claim in a practical way that seems reasonable to me.
                 I am not prepared to address the complex question of what
                 life is, but for the purposes of this discussion we can take
                 'alive' to mean 'a working reproductive cell, a bacterium.'
                 The latter is certainly a subset of the former.
                 What do you mean by falsifiable, then?  By the way, these kinds
                 of negative falsifiable claims are very common in AI.
                 For instance 'a computer program will never beat a human
                 world chess champion.' -- ilyas
                 \_ Modern bacteria are themselves the product of billions of
                    years of evolution. I don't think it's reasonable to expect
                    to put some stuff in a tube, shake it around etc., and get
                    bacteria. I personally think it's quite likely that life is
                    very highly improbable. In any event, just a couple hundred
                    years ago people still believed in spontaneous generation.
                    In general I find it absurd when people's response to
                    something they don't understand is invoking the
                    supernatural. It doesn't answer the underlying question
                    anyway; if evolution is a problem because it doesn't fully
                    explain the first bacteria, then ID is a problem because it
                    doesn't explain the intelligence.
                    \_ [nevermind]
                    \_ This is begging the question.  If the bacteria are too
                       complex to be produced directly, produce an intermediate
                       step, and then construct a story for how you get a
                       sequence of intermediate steps that would produce,
                       over time, and in a completely mechanical way, a working
                       bacterium.  There is currently no such story, but if
                       such a story were created (by logical argument, computer
                       simulation, whatever) then that would falsify the ID
                       claim.  This is difficult, but not impractical (serious
                       scientists are working on this very problem).  I still
                       don't really understand your objections.  Also, for the
                       47th time, I am not defending ID as either a credible
                       scientific movement nor an alternative to darwinian
                       biology. -- ilyas
                       \_ Wrong, as usual.  A line of reasoning doesn't
                          falsify ID; just because you can come up with a
                          way that something could have happened doesn't mean
                          that it happened that way.  -tom
                          \_ You seem to be confusing 'cannot' with 'did not.'
                             It's certainly possible to falsify 'cannot.'  It
                             may be possible to falsify 'did not.' -- ilyas
                          \_ Correct, but it still puts paid to ID's basic
                             tenet that 'x must have happened because of y
                             because x is so complex that it couldn't have
                             happened any other way.'  By creating a plausible
                             line of reasoning (in this case, how a bacterium
                             could evolve naturally) you debunk 'y' as a root
                             cause.  Remember "any sufficiently advanced
                             science is indistinguishable from magic"?  Once
                             you empirically explain a phaenomenon, you place
                             it into the realm of science and completely
                             remove all the superstitious voodoo crap.  -John

                       \_ You made the claim that ID had falsifiable
                          predictions. -emarkp
                       \_ Well, so ID is not verifiable but the claim is
                          falsifiable. How many other scientific realms
                          work like this? I'm not aware of any. It does not
                          seem to fall under the realm of the scientific
                          method. It's just an assertion... even if people
                          figure out a chain of events leading to replicating
                          pre-rna/rna/proteins etc. then ID can still claim
                          this stuff was "designed" to happen.
                          \_ I am not sure what you mean by 'verifiable,' but
                             no empirical theory can be definitely concluded to
                             be true, including relativity, evolution, etc.
                             This is why falsifiability is important -- a theory
                             is deemed stronger if it can withstand repeated
                             attempts to falsify its claims.  Evolution itself
                             had to be modified multiple times in the face of
                             legidimate (partial) falsifications.  To repeat
                             myself yet again, I am not defending ID as a
                             scientific movement.  In response to your last
                             sentence, I think the main ID claim as I understand
                             it has some 'teeth,' and Darwinists would be wise
                             to neither ignore nor attempt to discredit its
                             source. -- ilyas
                             \_ They can't be definitely concluded true but
                                they can be experimentally verified, e.g.
                                relativity predicts X we test for X, natural
                                selection being induced, etc. ID differs in
                                this respect. That main claim about life
                                being unable to arise without intelligent
                                design seems a different sort of beast. Not
                                the sort of thing one could really teach in
                                any substantive fashion, other than merely
                                mentioning it as a belief. It just says that
                                until we have "hard" verifiable theory about
                                exactly how cells arose, then we have to
                                talk about the "theory" that this was
                                impossible. I dunno, I'll go ahead and ignore.
                                \_ See below.  I think the difference is in
                                   degree, not kind.  Claims about the origin
                                   of life are more akin to cosmology or string
                                   theory claims -- falsifiable, but requiring
                                   immense resources for appropriate experiments
                                   to be conducted.  This does not invalidate
                                   the claims, it just shows how important they
                                   are. -- ilyas
                 \_ ^ what he said.  I suspect you know what I mean by
                    "falsifiable" -- a truth claim that can be proven false by
                    a test.  However, just because a hypothetical truth
                    statement can be falsified it doesn't mean it's useful or
                    seriously admissible.  When ID can suggest an experiement
                    that doesn't take an infinite amount of time to attempt to
                    falsify (defining terms and initial conditions, etc.) then
                    it should be addressed.  Not before. -emarkp
                 \_ Another thought: if the claim is that life can't arise by
                    chance, I don't see how creating a 'living organism' in the
                    lab would disprove that.  It would have to arise by chance,
                    wouldn't it? -emarkp
                    \_ That's a little obtuse, sorry.  Miller's experiment was
                       famous precisely because he created laboratory conditions
                       which reasonably duplicated conditions that could have
                       arisen by chance during early Earth's history. -- ilyas
                       \_ yeah, I'm sure the inability to create life by random
                          chance in a laboratory has great relevance to
                          whether it was possible to create life by random
                          chance on a sphere with a surface area of 200 million

                             never implied that ANYTHING follows if task X

                                         some criticisms for it, it is not
                                         dismissed outright.  The underlying
                                         nature of reality is an important and
                                         complex problem, as is the origin of
                                         life.  It's not unreasonable that a
                                         falsifiable experiment should be very
                                         expensive or difficult to conduct.  If

5/29    Any hobby astronomers here?  Can someone point me to a link with hints
        on how to read a star chart?  I have a telescope and have been playing
        with various planetarium-type apps (Starcalc looks neat) and am
        having trouble figuring out how to read the various projections--they
        all look back-assward.  Most "how to read star charts" links seem to
        deal with astrology.  -John
        \_ Redo your google search with "site:.edu".  That weeds out the
           astrology crap.
           \_ Thanks for the tip--I guess I'm just sort of unsure on a very
              basic level of what to look for.  I'm familiar with most of the
              terminology, but am hoping to find some sort of pointer to
              standing in a given spot with a conic or parallel sky chart,
              knowing which way is north, and then figuring out how to locate
              various objects based on the chart.  I'm just having trouble
              visualizing what goes where, if that makes any sense.  -John

                     [24 hrs about the celestial equator] and then declination
                     [like latitude]. or is your question about naming conven-

                        map of the night sky with compass directions, how do
                        I find object xyz from the map in the sky?"
        \_ skip the telescope for now.  buy a star chart from local store
           (to reflect proper latitude), get a compass, a flash light,
           warm clothing, along with the star chart you got, and go
           somewhere *DARK*.  If you are in the cities, where light
           pollution is severe, you won't able to make out anything in
           the sky.  In dark country side, once you got your orientation
           straight and date/time on the star chart properly adjusted, then
           you can actually match stars in the sky and the star chart.
           Telescope is only good for 1. planets such as Jupiter, Mars,
           Saturn. and 2. special event such as comets, eclipses, etc.

              bearings on how the chart represents what's actually up there,

4/24    Is a coffeemaker more/less efficient at boiling water than a
        microwave? What about versus boiling water in a pot on an electric
        range? Are they all about the same?
        \_ Most efficient is a coffeemaker because if has a heating coil
           immersed in water.  Stoves and microwaves are both pretty
           efficient.  The stove wastes heat due to it escaping around the side
           of the kettle.  The microwave wastes energy because the magnetron is
           not 100% efficient an converting electricity into microwaves.
           Least efficient though is when you brew using a coffeemaker and
           then leave the coffee warmer on for hours.  You should also
           consider the inefficienty of burning fossil fuels to generate
           electricity.  Best would probably be making coffee with a kettle on
           a gas burner slightly smaller than the kettle.
           \_ I wonder how much fossil fuels get used just to grow, harvest
              and transport the coffee beans to your home.  I'm guessing
              that if you calculated that, the added fuel use of heating
              the water would be insignificant.
              \_ I don't want to make coffee. I want to boil water. --op
                 \_ Uh, coffeemakers don't boil the water.  And if yours does,
                    something's wrong.
                    \_ Uh, yes they do. Just don't put any coffee in it and
                       you get a potful of hot water. It may not be boiling
                       hot, but hot enough.
                       \_ Uh, no they don't.  'Boiling hot' is not boiling.
                          If your coffee maker really boiled water it would
                          make gross bitter coffee.
                          \_ You're just a nitpicking git.

                                   that they don't because the water only
                                   reaches 210 degrees (or whatever).
                                   reaches 200 or 205 degrees.

              major problem. The astronaut needed a pen that would write in the
              vacuum of space. NASA went to work. At a cost of $1.5 million
              they developed the "Astronaut Pen". Some of you may remember. It
              enjoyed minor success on the commercial market.
              The Russians were faced with the same dilemma.

2/4     The hottest jobs in 2005 and beyond, and why I hate astronomers
        (because my tax money is used so that they can watch stars? what
        a waste!)            http://money.cnn.com/2005/02/03/pf/hotjobs
        \_ What the fuck are you blathering about?  Astronomers aren't even on
           the list.
           \_ lafe, third GIF chart to the right, astronomers on top column.
        \_ Astronomy leads to advancements in basic physics, which leads to
           practical achievements.  Astronomy gave us the theory of gravity,
           confirmation of general relativity, and neutrino oscillation, among
           others.  Also, that quick chart fails to mention that many
           astronomers in gov't research are P.Ii's with Ph.Ds plus 20 years
           of experience, while those in the private sector are often
           recent PhDs.
           \_ Astronomy also leads to multi-billion dollar space missions
              that creates hundreds of jobs for people working at Lockheed,
              Boeing, &c.
           \_ Even The Vatican has astronomers.  They use something called
              the "pope scope" (I'm not making that up, BTW).
              \_ I use something called a "poop scoop" for cleaning cat
                 litter.
              \_ Woah! I just checked around on google, and it turns out the
                 pope not only has a telescope, it's in Arizona!

                 \_ Still trying to disprove that whole earth/sun thing?
                    \_ I think the Pope apologized for the church's
                       persecution of Galileo and accepted the Helio-
                       centric solar system in the early 90s.
        \_ Who in the private sector hires astronomers?
           \_ Anyone having anything to do with satellites and aerospace,
              mfgrs. of visual navigation aids, telescope and star chart
              manufacturers, and do private universities with astronomy
              research departments count?  -John
        \- I believe there are a couple of areas where the public sector
           jobs are quite prestigious and get pretty good people. In some
           cases decent pay goes with the jobs. It's not the dregs of the
           law schools who become law clerks or work for the Manhattan DA
           or the SEC. The Fed has some top economists [yes I know the Fed
           is special]. In some cases you can't directly do public/private
           sector salary comparisons because in theprivate sector the same
           sector salary comparisons because in the private sector the same
           person would be doing a differnt job ... you might may a Aerospace
           Eng prof $125k while a Aerospace Engineer makes less ... but the
           really smart Aerospace eng prof fro, UCB could go solve differential
           eqs for Wall Street instead and twice as much ... but that isnt
           captured in the private sector income stats for Aerospace.
           I'm happier about my tax money going to peer reviewed hard science
           research than Halliburton's passed expenses.
           \- BTW, to echo the fellow above, I think the astronomer case is
              an anomaly because they are so very concentrated in NASA, a
              govt angency known has being very seniority heavy ... and who
              knows what private sector astronomer even means ... maybe they
              are jr. high school science teachers.
              \_ Heh. When I was in junior high, I had a science teacher who
                 taught part time who had a business card that said
                 "astronomer". I think he had several part time teaching things
                 going and did some random consulting.
              \_ How are they defining public/private? Is MIT public or
                 private under this definition? What about Aerospace Corp.
                 or RAND?
              \_ Jr. HS Science teacher is generally in the public sector.

2/2     Dear motd physicists, suppose I have a) 5 100W light bulbs and b) 500W
        heater. Suppose put them in 2 different thermal tight boxes, each with
        a liter of water. Will both liter of water have the exact same
        temperature after time t?
        \_ No, because 5 light bulbs have a different heat capacity than a
           500W heater.  If they were the same, then yes, the water would have
           the same temperature.  There are of course special cases where this
           would be different, but 5x100W light bulbs create just as much heat
           as a 500W heater.
           \_ You just contradicted yourself.
              \_ He didn't really. He said they create just as much heat, but
                 have different heat capacities. Although I'm curious about the
                 special cases she mentions.
                 \_ I was thinking stuff like differential evaporation rates
                    and transient higher electrical loads.
        \_ One thing to note is that by saying a light bulb is X wats, it does
           not mean that it puts out X watts of heat; it just means it draws
           X watts of energy. What is does with those X watts depends on
           the type of bulb and other details like that.
           \_ It can basically only put off various forms of electromagnetic
              energy and sound.  If it's placed in a perfect calorimeter
              (OP's 'thermal tight box') then all the energy it consumes will
              be turned into heat.
        \_ You're probably limited by the conductive heat transfer at the
           air-water interface.  Probably the only difference between the two
           rigs is how much energy goes into visible vs. infrared, and that
           probably won't matter as the water won't likely heat up very much.
           \-to spell out the first reply:
             the simple way to thinks of this is in terms of the Partition Of
             Energy. the energy in the system will be divided between the
             water and the heating apparatus. at T0, with energy E0 = Ew0 +
             Eh0 (or Eb0) [total energy = energy of water + energy of bulb/
             heater]. at T1, E1 = E0+dE = Ew1 + Eh1 (Eb1). Since we are
             assuming dE is the same in both, Ew1 is identical iff the Eh1
             and Eb1 are the same ... which is dictated by the heat capacity.
             [and the heat capacity of the water is how you go from the
             Ew to the water temp]. Note: in some cases the parition of
             energy is more complicated and you have to taken into
             consideration entropy factors. Like say you mix metal A and B
             into an alloy ... as the compositoon goes from 100% A to 100% B,
             the melting temp of AB doesnt go in a stright line from meltA
             to meltB.
             \- oh here is another one: you take a spring and spend energy E
                to compress it. then you put it in an acid bath, where does
                the energy go, if it dissolves from the end.
                \_ In a compressed spring, the energy is stored in the bonds
                   between atoms.  As it dissolves, these bonds get broken one
                   by one, and when that happens, the 2 atoms whoose bond was
                   dissolved convert that bond energy into heat.  So a
                   dissolved compressed spring will be hotter than a dissolved
                   relaxed spring.

                       fact! :-P
              \_ $3 billion is not a lot of money. A stealth bomber costs
                 about $1 billion. Not only do you have to design and
                 build a unique spacecraft, but you have to track it and
                 fly it for 7 years. Some of the science is also paid out
                 of that $3 billion. There's a lot of infrastructure to
                 be able to do something like this at all, from engineers
                 and scientists to security guards and janitors. It all
                 has to be paid for. Look at it this way: every senior
                 scientist and engineer costs $250K per year including
                 benefits and you haven't even built or launched anything
                 yet. To compare, MSFT spends $6-7 billion each year
                 in expenses and a lot of what they do is not as highly
                 specialized.
                 \_ NASA pays its engineers $250K/yr? Crap, I am in the
                    wrong industry.
                    \_ he said including benefits, which typically cost
                       a large percentage of the base pay in the first place.
                       but i doubt even their most senior technical
                       people get paid a whole lot more than 150K.
                       \- hola, if memory serves, NASA has a huge
                          number of old people on the rolls. few younger
                          people are begining their careers there anymore.
                          i suspect this means their avg costs [high salary,
                          high health care costs, looming pension costs]
                          are fairly high. ok tnx. --fmr nasa employee.

                             +60yr old : <30yrs employee ratio is 3:1 at nasa.
                       \_ Right. High-level scientists and managers might
                          get $250K, but most are in the $100-150K range.
                          However, there are good retirement benefits and
                          other perks. When I do my budgets I plan about
                          $250K for a senior person, because of the
                          overhead. They aren't getting that much in their
                          pockets, but it is still spent. BTW, there has
                          been a lot of hiring of young people in the last
                          5 years or so as NASA tries to reverse the
                          trend. There are also a lot more PhDs now than
                          there were in the 1970s.

1/9     What does "run aground" mean? -silly sodan
        \_ When a ship or boat goes through water that is not deep enough,
           the bottom of the boat, usually the keel, kits the "ground".
           Typically the boat was moving forward at the time of impact
           and a sudden loss of forward speed produces an uncomfortable
           and a sudden loss of forward speed (lurch) produces an uncomfortable
           sensation at the least, and damage at the most. Depends
           if the bottom is sand or rocks. Big difference..
           \_ Thanks. So does subs have sensors to detect these things?
              \_ The run of the mill sonars you'll find on commercial fishboats
                 give a pretty decent image of the bottom of the ocean, and I'm
                 guessing that a nuclear sub would have something way way
                 better imaging in all directions, not just along the axis
                 of travel of the boat.  Something or someone fucked up, and
                 I'm guessing the real story will not be reported in the news.
        \_ How funny. I thought the same thing when I read the same news article.
              \_ Active sonar maps fairly well.  Subs are often trying to run
                 silent, and active sonar defeats that.  They rely on charing
                 done by surface ships.
                 \_ In sufficiently deep waters there's a certain depth at
                    which sound speed stops decreasing with depth (because of
                    colder water)  and starts increasing (because of increasing
                    pressure).  If you put your sub on the bottom side of this
                    depth it impedes the ability of surface ships to detect you
                    because the change in sound speeds reflects some of your
                    sounds back down.  If you have a ship running silent (with
                    their depth-on-keel gague off) and trying to keep under
                    this fixed depth, you could have a problem if the water is
                    not too deep and there's a charting error.  So... what you
                    said.
           \_ This is a lot of congecture based largely on Clancy novels
              and watching Hunt for Red October, but I think the difference
              between fishing boat sonar and nuclear sub sonar is that
              fishing boats use active sonar and subs try to stay hidden
              and use passive sonar. With passive sonar, you would rely
              mostly on accurate sea floor maps for navigation. If mis-
              calculate speed, heading, or time then you could be off course
              enough to hit things you are trying to avoid in tight spaces.
              I'm not sure they still use innertial navigation. It definitely
              seems plausible. -saarp
              \_ I believe they use high freq sonar for getting through
                 icy regions without giving themselves away.  Perhaps
                 there's something similar they use for keel depth?
        \_ How funny. I thought the same thing when I read the same news
           article.
           \_ what news is this?  -- sodan who get all news from the motd
                \_ I read it on the front page of cnn yesterday.
           \_ Is it something about the South Asia earthquake reshaping seabeds
              because it elevated seafloors and the tsunami moved around ships
              that sank decades ago?

12/15   Anyone know how laser distance measurement work? Intensity of
        reflected light? But doesn't that depend on the reflecting
        surface? Curious. Thanks.
        \_ I thought it was the time-to-travel of a beam of light. I assume
           you mean far distances.
           \_ I recently tried a Leica Disto laser measurement device, it
              can measure from 1 ft up to 600 ft. Just wondering how it
              works because it seems to be pretty accurate and works on most
              surface I point it at, even tree leaves at night.
        \_ It modulates the laser's strength to produce pulses, and then with
           a high-resolution timer it can tell how long it took for the
           roundtrip.  An advantage of this is that the shininess and distance
           of the target do not effect the measurement as long as they are not
           too far and too dark.  If you shone it on a smooth enough mirror
           at the wrong angle, you could disrupt the measurement though.
           \_ wow, how high resolution of a timer are we talking about?
              This is speed of the light we are talking about. Something
              comparable to timer used in GPS? But those are much further
              away...
              \_ For ~1-meter resolution, you need 3ns resolution.  I know
                 higher-resolution timers are available, as for price, no idea.
                 \_ The clock period on a 2GHz Pentium is 0.5ns, and the chip
                    costs only a couple hundres dollars.  So I guess a timer
                    with 0.5ns resolution would cost much less than that.
                    Come to think of it.  Light is not really that fast.
                    \_ If you mapped all speeds onto the domain [0,1], light
                       would be 1.
                       \-"we have measured the charge of the electon ... and
                          it is 1" --psb
                       \_ I suppose it can be the fastest and still not be
                          "that fast". After all, the universe seems a lot
                          bigger than light seems fast. Or perhaps it's just
                          that our sense of time is too fast, since we live
                          so short.
                             \- gee what other free parameters seem too
                                big/too small?
                          \_ Size of universe = age * speed of light.
                             If you think the universe is bigger than light is
                             fast, then that's just saying the universe is old.
                             Your preception would remain the same no matter
                             how fast light it, because the universe would be
                             bigger.

                                      so the speed of light in a vaccum was

                                      moved through the universe. ok tnx.
                                      \_ While the speed at which photons can
                                         cross the universe is not always C,

                                               answering the empirical Q and
                                               and attempt to do better. the
                                               real point of course is we have
                                               some observational data for size
                                               so really what we are trying to
                                               figure out is age.
                                is there debate among scientists on whether the
                                universe is growing at an accelerating rate,
                                constant rate, or decelerating rate?
                                \_ It *is* more complicated than that, but I
                                   wanted to gloss over that fact because for
                                   purposes of comparing non-comprable huge
                                   values (light-speed vs. universe size), it's
                                   about right.  If you want to do actual
                                        \_ You are assuming that the expansion
                                           of space is limited by the speed
                                           of light, correct?
                                   cosmology, you need to think about tensors
                                   of 4-dimensional non-euclidean geometry, but
                                   that seemed beyond the scope of this debate.
                                   \- um without looking for explanation that
                                      involve really exotic theories and
                                      fancy math like M-theory and supergravity
                                      the two big Qs in cosmology today are
                                      1. the missing mass question and the
                                      2. the hubble constant/cosmological
                                         constant question ... some recent
                                         observation are seeing some curious
                                         phenomenon in high red shift objects.
                                      in both cases there has been a lot of
                                      study to rule out dumb mistakes but now
                                      a lot of physicists believe something
                                      big is missing from our theories and
                                      models. on a parochial note on topic #1
                                      the dark matter studies are a major
                                      funding priority for the govt and on #2
                                      a lot of the seminal work is being done
                                      at lbl (smoot, permutter, borrill etc).
                                      there are a lot of decent and fairly
                                      accessible books on these topics
                                      as well as many good WEEB pages at

              \_ It turns out that time is what we're best at measuring.
           \_ How do you tell pulse from one another? How do you identify
              the return pause is the one you sent x time ago?
              \_ Imagine you space your pulses out by, say 1ms.  This lets you
                 measure up to 1000 pulses per second, each can have a maximum
                 roundtrip distance of 300km, which is way more than you can
                 measure in practice.
           \_ I thought reflection is absorption and re-emission of photons.
              Does that happen instantaneously?  If not, does the delay depend
              on the surface material of the target?
              \_ It's not instantaneous, and it does depend on the elements
                 present in the surface, but except for a few special cases,
                 the delay is inconsequential in this type of measurement.
        \_ Yes, if what you're pointing at is a black hole, you're scr00ed.
           \_ Has scientists confirmed that black holes exist?
              \-yes, essentially. --psb

12/13   So I called this girl and she told me something that was
        very different than the other girls-- kind, unambiguous,
        yet effective. She told me that she was very busy feeding
        her goldfish and she couldn't go out with me. Now I'm wondering
        what some of the cool rejection lines you losers have to share?
        \_ Tell her to go fuck herself. If she can't give you an honest
           answer, she's a total bitch.
        \_ Laurie Anderson had an idea to turn Gravity's Rainbow into an
           opera; she asked Thomas Pynchon for the rights, and he told her
           she could do it on one condition: the only musical instrument
           allowed would be the banjo.  -tom

        \_ "You're too good for me."
           \_ what does this mean?
              \_ you're not good enough for her.
        \_ Not a dating thing, but while I was on my mission, a guy told
           me he was "too busy to meet us."  He was watching people play
           starcraft on TV at the time.  -jrleek
           \_ the only good missionaries are the female ones that enjoy
              the missionary position.
           \_ No offense, jrleek, but unless I'm truly bored and aching for a
              theological fight, I will always be too busy to meet with
              missionaries.
              \_ On my mission I actually shook hands and thanked people who
                 simply told me "not interested" instead of giving a lame
                 excuse, giving me a time when they wouldn't be home, or simply
                 not answering the door when I arrived when they asked me to.
                 -emarkp
                 \_ it is my right to give you a lame excuse if i don't
                    want to talk to you.  i'm sure missionaries have
                    thick skins or they wont be missionaries for very long.

                 \_ I wish all missionaries were that polite.  I've actually
                    had to close the door on a couple guys on their mission
                    because they wouldn't leave after the 3rd time I told them
                    'not interested' -- in very polite and clear terms.  It's
                    people like that that make it so much easier to be rude
                    using the dodges you mention rather than risk having to be
                    even ruder by just closing the door in midsentence.
                    \_ Yes, I think anyone going door-to-door (which I actually
                       did very rarely) needs to be extremely polite, and then
                       people answering the door need to be honest, and then
                       brutally honest if necessary.  -emarkp
              \_ No, you don't want to meet with missionaries.  Which is
                 fine, if you don't want to meet with me, I don't want to
                 meet with you.  I don't get off on wasting my time.  It's
                 just funny to claim you're "too busy" while watching
                 StarCraft on TV. -jrleek
                 \_ Hey what channel is StarCraft on TV? I'd totally want to
                    watch that. I think I've flaked on my friends bc I was
                    busy watching the crazy knife selling guy on QVC.
                    \_ It's a Korean thing.  They have pro-StarCraft
                       players and a cable channel dedicated to playing
                       video games.  (Which is most StarCraft, at least it
                       was when I was there 2 years ago, and the Koreans
                       are still into StarCradt AFAIK) -jrleek
                       \_ I first read that not as a typo, but as a joke on the
                          way a lot of asians pronounce 'Sta-Ku-Raf'
                 \_ When they come to my door, I usually tell them to get lost
                    in no uncertain terms, and demand that they never come to
                    my door again.  If they question, I tell them *exactly*
                    where they can stick the whole concept of organized
                    religion.  Which do you prefer?

           planets, no space stations with any real life or industry.)
           I can see the excitement of space *science*, done by robots,

           \_ Wow, you are crazy. -- ilyas
        \_ Hell yeah! When do we go?
        \_ What's this 5% based on?  If number of fatal missions out of total
           missions flown, then this is somewhat misleading; cf. the number
           of fatal flights out of total flights flown versus number of fatal
           flights this year out of total flights this year for air travel
           safety parallels.
           \_ I don't think it's based on anything.  You're reading far too

                to bring the out of pocket costs to say $2500,
                i'd go. probably if you die, you die pretty fast.
                i think the odds of a horrible death are lower.

              commercial product.
        \_ Digipede may also be what you're looking for.
        \_ Condor is the most mature cycle scavenging system and is
           sort of half-commercial out of U. Wisconsin.  works for a large

           no silver bullet if you haven't already decomposed your

           \_ I agree with this. Condor is the closest. Lots of people
              have something similar, though. We run something we got from
              Argonne and modified ourselves. Good luck finding something

           \_ It says the tank is standard 1.6gpf and the tank in picture looks
              bigger than 1.6gal.  So I guess there's a tank within the fish
              tank which holds the actual water for flushing, and the fish
              lives in the surrounding task.
              lives in the surrounding tank.
        \_ I saw something like this in Korea.  They had a fish in the
           water tank that took up about a quarter of the total tank
           volume.  (Big fish, small tank.)  Everytime you flushed all the
           water would drain out and the fish would just sit there and
           flop around until the water got back up to where it could
           breath again.  It was kinda disturbing, but I guess it keeps

8/3     I can't tread water. I was at a party a few days ago and another guy
        there was talking about how he couldn't tread water either. Another
        person overhears him and mentions that she can't tread water either.
        Is this a very common problem? And why can't some people tread water?
        Is it just a matter of technique, or are people like us just too
        dense to float?
        \_ it's a skill that can be learned. I'm not very buff, and am not
           overwieght, and can tread water without much energy expended
           because of swim lessons and practice.  find someone who
           knows how, and get them to show you, then practice.
           it could save your life, so it's worth it.
        \_You just need to work out a LOT more. Treading water is very
          energy intensive and requires strong legs with very good stamina.
          Why do you think water-polo players are so fit?
          \_ I have seen others who make it look effortless. Like the opening
             scene in Jaws, the woman doesn't even look like she's trying.
             \_ Yes, and Tiger Woods makes driving a ball a couple hundred
                yards towards a small green effortless. It doesn't mean
                he just picked up golf yesterday...
                \_ I was trying to dispute the "energy-intensive" point and
                   not so much the skill aspect. The woman in Jaws does not
                   appear to be expending much energy at all.
                   \_ ahh yes.... movies...
                      \_ that's right, because back in 1975, it was worthwhile
                         and cost-effective to make a shot of a woman swimming
                         in the ocean an FX sequence
                         \_ ocean == saltwater == easier anyway
       \_ When you say treading water, do mean just using your legs to
           stay afloat, or is using your arms ok too?  With arms it's
           pretty easy, with just legs, it's pretty hard.
        \_ What do you mean by treading water?  Walking in the pool or bathtub?
           Or the Jews walking through the red sea?
           \_ Imbecile.  Obviously he means walking on water, like Jesus.
              If you followed the thread, you would have read that none of
              his co-workers could do it, but water polo players can do it
              because they're *very fit*.
              \_ you don't read so good, do you?  water polo players can
                 walk on water because they're jewish.
                 \_ You're right.  I re-read the thread and it's clear that
                    what you wrote is 100% accurate.
        \_ re density: can you float on your back?  shouldn't take any energy
           to keep mouth and nose out of water in calm water; may take a little
           effort if there is chop/waves washing over your face.
           i agree with first reply; i swam competetively as a youngster
           and am at ease in water... treading water is easy and i could do it
           for hours in a pool.  it's a little harder while holding a beer in
           one hand and keeping the chlorine out of it.
           oh, also: control your breathing.  shallow breathing with lungs
           full of air is a lot more bouyant than deep exhalations.  if i exhale
           forcefully i can sink to the bottom, but it counters years of
           swimming instinct.
           \_ Not OP, but I can't float on my back, and I've tried in a pool
              and open water. I even had my gf at the time try to keep me up,
              but I simply kept sinking. Not sure why.

7/12    Question about the BART ticket encoding system. Do they attach a
        unique id to each card, and have all the stations connect to a
        central computer that keeps track of the states (which is more secure
        but less reliable because in the 70s the network communication was
        not as reliable as now), or do they encode the actual amount of
        money onto each card (which is more fault tolerant to network
        noise, etc)? ok thx.
        \_ I can't speak for BART but Singapore's MRT system uses RFID
           cards for both bus and train services. AFIK, it would be
           really expensive to have RFID cards self modifying (especially
           when they have no batteries). It would be easier to use a
           centralized server and that's probably what they do.
           \_ Are you sure it's RFID and not some sort of induction mechanism?
              I think that's what RATP (Paris metro) use.  About contactless
              smart cards:  http://tinyurl.com/6su5r   -John
        \_ The latter. I have fantasized about getting a card reader
           and writer and making my own BART cards. It uses some
           simple encoding, if I remember correctly. I can dig up
           my research no this, if you like.
           \_ You know this is how one of the hosts of Off the Hook got
              a felony conviction, right?  It's not worth it.  If they catch
              you, expect the whole paranoid Mitnick style treatment by the
              courts.
              \_ He got a felony conviction for making a fake BART card?
                 I find this hard to believe. URL please.
                 \_ it was MTA in new york, and not BART.  I don't have a
                    url, and he doesn't discuss the details of his case
                    on the radio, but he's definitely on probation from
                     felony charges, and whatever he did was
                    definitely involving MTA cards in some way.
              \_ "Your honor, he was 'hacking' BART, a vital public resource.
                  If his plan had been allowed to spread, it would have had
                  serious impacts upon BART's ability to evacuate people in
                  the event of a disaster.  We ask that the court consider
                  the defendant to be an enemy combatant."

                     for the government to make your life into a living hell.
                     I think the PP is pointing out that a felony crime

                        with DHS.  The paranoid idiocy about computer
                        related crime goes back to at least when I was
                        in highschool in the early 90s.  My highschool physics
                        teacher atually testified that some idiot who was caught
                        with bomb related stuff on his bbs and some stolen shit
                        in his home (which the cops raided swat style) was
                        "neither evil nor a genius."  They really wanted
                        to throw the book at him becuase prosecuters get all

                   \_ What's LOR?
                        \_ Lunar Orbit Rendezvous. There were three
                           different proposals to get to the moon:
                           1. Direct
                           2. Earth Orbit Rendezvous (EOR) - Launch
                              the bits into space separately, link
                              up in Earth orbit, go to the moon, land
                              and come back
                           3. Lunar Orbit Rendezvous (LOR) - Launch
                              this bits into space separately, link
                              up, go to the moon, land only part of
                              the craft on the moon, link back up
                              in orbit around the moon and come back.
                           LOR was the most/least complex depending
                           on your point of view. Most complex because
                           it has so many places where it could go
                           wrong. Least complex because it required
                           smaller rockets and smaller simpler lander.
                           Gemini is also of interest, because that
                           was the platform that proved that rendevous
                           and other systems could work.

                           http://oea.larc.nasa.gov/PAIS/Rendezvous.html
        \_ I've thought about this before.  I decided it's very unlikely that
           they have unique tickets that are tracked by a central server.  If
           they did that, the server would have to be able to store hundreds
           of millions of unique tickets (dating back 30 years) and there would
           have to be a way to instantly process transactions from about 1,000
           terminals spread over a 50-mile range.  Nowadays it's more-or-less
           doable, but in the 1970's it would have been a huge PITA.
           \_ ah yes, but they could have easily done it with well known
              techniques like database duplication, local caching, database
              merging, backup modems, etc.
              \_ BART can't even get the machines working well enough to
                 print the fucking ticket values.  -tom
              \_ Each ticket record would probably need to store 6-8 bytes in
                 a unique-tickets situation.  Then you need to be able to store
                 several hundred records at every station in the 1970's.  How
                 did a meg of disk cost in 1975?  Like I said, it would have
                 been possible, but huge pain for marginal benefit.
        \_ The amount of money is encoded in each card. It used to be printed
           in human readble form on the card every time it was used as well
           (not sure if this is still the case). The start point of your
           journey is also encoded so that when you exit it knows how much
           to deduct.
           \_ It still is printed, BART is just really bad about changing the
              toner ribbons in the turnstiles.
              \_ 1) This is true, they do need to replace the toner cartridges
                 more frequently, and 2) your ticket is supposed to have the
                 amount remaining printed on it _when you exit BART_. Many ppl
                 think the amount is written when you buy your ticket or enter
                 BART, but that's not the case.
                 \_ It IS printed (fairly reliably) when you buy your ticket.
                    It gets printed sideways next to the mag-strip.
        \_ I remember my dad (who worked at BART as a techie since 1972)
           telling me of a fraudulent cards they came across in the 80s.
           they were made out of index card stock w/ VHS tape glued down
           for the magnetic strip.  but if you're interested in tech politics
           ignore the ticketing system and try to find out about hte train control
           system and the wayside communications.  what a mess!

1/30  So to summarize.  The biochemical path taken by developing life was
      swept clean by later, more sophisticated life such that no empirical
      evidence exists for any biochemical path whatsoever.  Moreover,
      scientists don't have a complete, compelling theory, even though they
      are unburdened by ANY possibly falsifying evidence.  Well, I will say
      that support for 'life started on earth' is about as strong as support
      for any other hypothesis, including 'life started on mars', 'life started
      on the moon', 'life was brought here by aliens,' etc.  Keeping in mind
      that mars and moon may have a better preserved record than earth, and
      that aliens may have evolved like scientists think: from chemistry.
        -- ilyas
        \_ the problem with all this stuff is that you can always go one step
           back and say "ok so how did that happen?  what predates that?" all
           the way to the 'beginning' of the universe (if there is such a
           thing) and then you get into, "ok, so how did the universe come
           about?" which leads to various religious concepts or the equally
           oddball stuff coming from physics.
              \_ what oddball stuff are you talking about?
           \_ Yes but you only have to go back a little way before you start
              running into contradictions with religions like Christianity.
              (And no, I'm not talking about stuff like "virgin birth"; aside
              from the biological debate, biblical details such as whether
              someone was a virgin are impossible to verify.)
              \_ A lot of it can be written off as errors in translation and
                 misunderstandings over time.  Even so, if all religions could
                 somehow be proven to be untrue, you still have the same
                 problem with going back and back and back to "how did the
                 universe come into being, from what, and what was 'here'
                 before (wherever 'here' might be in that context?".
      \_ Humans like to think things are magic. Historically they thought things
         from weather to illness were supernaturally controlled. All through
         history, the more we learn about the universe the more we see
         how things result from natural processes. At the limits of observation
         we don't have all the answers, but we can make reasonable conjectures
         that don't involve magical beings. We know a lot of organisms for which
         we have almost no fossil record (e.g. except in amber, which obviously
         only existed in an advanced age). We have some chemical evidence for
         self-replicating processes that could occur.
         Humans also think things are magical when they are improbable. For
         example, when a someone comes out unscathed from a huge disaster.
         But these improbable things too have natural explanations. And it's
         not improbable that the lottery will have a winner.
         But these improbable things too have natural explanations.
         otherwise.  [moved because it made the other replies to op look like
         replies to this which they weren't]
         \_ Argument from history is not enough.  I can also use such an
            argument another way: 'Historically, we could always find some
            intermediate form organism or "living fossil" living in the
            backwoods of the amazon, or some deep sea trench.  Why can't
            we find the lifeform intermediate between a chemical and a
            bacterium?'  Personally, I find the existence of life truly
            puzzling.  Right now we have no answer.  Nor did my alternative
            hypotheses postulate magical beings (or magic of any kind),
            although I don't reject magic either.  I also have problems with
            some feats attributed to evolution, but that's another story.
            I don't see _any_ support for 'life started on earth' at this
            moment.  It's cheaper to assume spores traveled from mars, and
            hope mars has something illuminating in the rocks, than to assume
            carbon and hydrogen combined to form a replicating machine
            involving three separate components (each a giant molecule), none
            of which can function without the other two.
              -- ilyas
            \_ How so? How is it cheaper to assume spores traveling from Mars
               than a primordial soup of amino acids getting a spark from
               the nascent Earth atmosphere? In the first case you still need
               to explain where the spores came from, and then explain how
               it is they happen to be capable of surviving the journey from
               Mars, not to mention what force caused them to suddenly
               migrate to Earth at just the right moment to get sucked into
               the Earth's orbit rather than the much more likely scenario of
               the spores missing Earth completely and ending up in the Sun.
               If you're willing to assume that many coincidences, why not
               believe that the elements on Earth just happened to fuse in the
               right way to form the essential amino acids that form the basis
               for life?
               \_ Because there are lots of spores, and they can survive the
                  trip (spores from bacteria on earth routinely go off into
                  outer space, they are found at all layers of the atmosphere).
                  Also, because it's more likely life arose on Mars, given a
                  good fossil record on Mars (which may or may not exist --
                  we don't know, but we can't rule it out), and traveled to
                  earth than it arose on earth, given no record before bacteria
                  at all.  The missing variable here is whether there is
                  some location 'close by' where a good record exists.  In my
                  mind the probability for something like that shoots up, if
                  there is nothing here on our rock.  I don't buy the argument
                  that every single trace of pre-bacterial life simply
                  disappeared.  It just never happened at any other stage of
                  life.  -- ilyas
                  \_ 1) So because it never happened at any other stage of
                     life, _so far as we know_, it's unlikely to have
                     happened?  2) We have possible traces of pre-bacterial
                     life in the structure of our own cells and in our DNA.
                     3) If we find that fossil record on Mars or the Moon,
                     then I will certainly give your theory more credence;
                     until then, the idea that multi-cellular life is the
                     result of random molecules bonding and that subsequent
                     iterations of such life wiped out the traces or our
                     equipment is still too insensitive to detect the evidence
                     sounds much more likely. I don't expect to convince you,
                     but I do want you to understand why some of us disagree
                     with you.
         \_ humans like to think probable things are improbable, due to
            inappropriate assumption of (combinatorial) conditions that
            are really independent...
         Bottom line, there is more support for "life started on earth" than
         otherwise.
        \_ ok...so?
        \_ the problem with all this stuff is that you can always go one step
           back and say "ok so how did that happen?  what predates that?" all

              with their overseas holdings, went bankrupt a few times due
              to the inflation caused by all the gold they plundered, etc.
              Even leaving morals aside, conquering stuff isn't always the
              best thing to do for a country. -- ilyas
              \_ No problem, just don't have a 'mars rock' based economy.
                 As of this date it doesn't appear there will be any natives
                 to exploit so there's no morals issue.
                 \_ Sure there is.  Whenever public money's used for something,
                    you need to make a moral case for it.  Also, it's not
                    really about the gold.  Expanding the country is just like
                    expanding the economy, it has to be done 'organically' or
                    you get counterproductive results, like inflation or
                    revolts or whatever.  In the case of Mars I don't even
                    see a non-scientific reason to go.  Personally, I think
                    there are better ways to explore space than NASA (and
                    better ways to spend government money than NASA).
                      -- ilyas
                    \_ You don't need a morals case to spend public money.  You
                       need a "public good" or "national good" case to spend
                       public money.  Or you should, anyway.  You don't see a
                       non-scientific reason to go?  Neith do I.  I think the
                       scientific reasons alone are reason enough.  I agree
                       that NASA may not be the right place to spend the money,
                       but we should continue the/a space program.  Putting
                       everyone on the dole is not in the public's best
                       interests and certainly immoral.  See the Indian
                       Reservations for how that works out (or not).
                       \_ "Public good" is a (utilitarian) moral argument.  A
                          lot of people, btw, will disagree with this sort of
                          argument for spending public money, either because
                          they themselves are not utilitarian, or because they

                             by the government, those on the reservations were
                             essentially destroyed as a viable people.  Entire
                             generations were lost to Indian "welfare".  And

                                while certainly not perfect, gave some people
                                on the Res. space to concentrate on more than

                                   destroyed the tribes.  It was the last

        "Apollo was drilled into space with the giant Saturn V rocket, the most
        powerful launcher ever built by the United States. After the Apollo
        program ended, the equipment, tools and plans for building the rocket
        were lost."

        \_ I think the author is using 'lost' as an overly-dramatic synonym for
           abandoned or discontinued.
           \_ I've actually heard this before.  As in, in order to recreate
              a Saturn V rocket at this point in time, either one would have
              to be reverse engineered, or all new research would have to be

        \_ i think SETI is a seriously premature attempt. Of all the

           likely signal, which is in fact extremely unlikely, consider
           that there are SO MANY altneratives.
           i propose a model for deciding how to run government projects:
           give the rational researcher his money. see if he'd rather
           spend it right now on his research or put it in some fund with
           return X to and see how long he will wait for the available
           technology to mature before undertaking his endeaver with this
           appreciating captial.

              That there may or may not be a consensus on the simplest
              explanation is completely irrelevant.

              fair, NASA has far stupider political constraints.  -John
              \_ "NASA's budget" is building the stupid space station, not
                 sending probes to Mars and therein lies some of the problem.
                 The Shuttle was the historical money pit and even that is
                 being shortchanged for the ISS.
                 \_ Fair enough, that's why I mentioned politics.  But the
                    Russkies and Japanese aren't sending anything to Mars
                    either;  in fact, isn't the only reason the ISS is able
                    to operate the fact that only the Russians have capable
                    supply ships?  And I recall reading something about a
                    US-built rescue craft that was supposed to be ready a
                    while ago.  I think most people realize what pressures
                    NASA has to work under, but as an uninformed Joe Schmo,
                    I distinctly get the impression that anytime NASA is
                    confronted with criticism, the reaction is always

                \_ and this guy gets his news from msnbc.
           \_ Well, why do they always have some investigatory session where
              they find out about serious design flaws? Shouldn't they have
              these reviews in a serious way before the thing goes live?
              \_ The design flaws are almost always known in advance. Rare
                 is the unforeseen problem. The problem is knowing which
                 problems will kill you and which will not and deciding if
                 it is worth it to correct them. Many flaws are only
                 "serious" in retrospect (i.e. after they caused a failure)
                 and there *is* a budget to meet. Current missions are being
                 flown for a fraction of the cost of those done in the 1970s
                 which were much more successful, not surprisingly.
           \_ What's most troubling is that many of the criticisms
              Richard Feynman made during his investigations of the
              Challenger accident seem to have occured again in the
              Columbia accident.  Obviously, space exploration is still
              very experimental and prone to accidents, but as someone
              who works for NASA, maybe you can tell us if most of
              Feynman's chief concerns have truly been addressed in the
              almost 18 years since.

                  to the right number of decimal places.
               \_ Yes.  4 quarts to the gallon, 2 pints to the quart, and 4 cups
                  to the pint.  1 cup = 8 fl. oz.
             \_ can either of you fools do basic arithmetic?
        \_ There was an recent article in Runner's World magazine basically
           debunking the 8 cups/day myth. They could find not one bit of
           scientific backing to support it. They said 8 cups a day is
           overkill for most people, though it doesn't hurt (they actually
           recommend about 6 cups a day, more if you exercise).

                 humidity, temperature, altitude, or metabolism.  That's
                 the stupidest shit i've ever heard, and no i don't care

                    is the minimum you should drink, but it's your

                       of four, pressure that people live in can vary as much
                       as 25-30% by elevation, and temperature and humidity
                       that people live in can vary by absurdly large amaounts
                       also.  Common sense dictates that there is at least
                       a factor of four difference in the minimum healthy
                       water intake for different people under different
                       circumstances.  My observation of having to deal with
                       pre-meds in college is that they lack common
                       sense, and so i don't really care how many doctors

10/18   Does anyone have any ideas of how to cure a wet phone? I accidentally
        kept my phone in my pants as I ran them through the washing machine.
        \_ Run it through the dryer to dry it out!
        \_ Prob hosed. Buy a new one.
        \_ I forgot I have my clunky old motorola startac phone in my shorts
           pocket when I jumped into the fox river to pull my canoe to
           shore.  The phone would not power up at first, but slowly came
           back to life after a few days (no response -> static -> power
           up and down constantly -> works).  However, it did develop a
           problem where once in a while, if I flip it open or close too
           fast, it would power off by itself, which is quite annoying.
           Try to be patient and wait a few days before powering it up.
           All the phone numbers in the phonebook still remained.
                \_ I actually have a startac (that hasn't been
                   drenched yet) that has that same problem (turning off
                   by itself when I flip it open/shut too fast). So
                   your startac is probably fully functionally then.
                   \_ good to know. guess it's a systemic phone problem then.
        \_ it is NOT hosed! You need a LOT of work and patience to save its
           life. First of all, if there are contaminants inside the phone,
           you gotta get rid of them. Contaminants include sugar goo, salt
           (REALLY bad), and other chemicals. You gotta get rid of them by
           dipping the entire phone into DISTILLED water. It must be distilled
           water or else it's no good. Then shake the phone for a few minutes
           while in the distilled water, and repeat using new distilled water.
           Do it a few times, 10-15 would be ideal. Afterwards, you gotta
           dry your phone. Do NOT, I repeat, do NOT power on the phone when
           it is wet. Now wait 3-5 days while baking your phone under the
           sun and then give it a try. It should work afterwards.
           \_ I'd suspect you of spoofing, but this sounds just crazy enough
              to work....

        Freelancer is from the Elite/Wing Commander genre.  It attempts to
        capture the Elite be-anything-you-want (trader, miner, bounty hunter,
        etc) feeling but you're mostly stuck on the single player main mission
        path to the end.  You can diverge and ignore it relatively early if you
        want but unless you already know what you're doing you're better off
        following the pre-chosen path.  Space combat is lacking.  All enemy
        ships appear to use the same AI routine.  There's no radar, only a
        bunch of red arrows around the outside of the HUD showing you the
        general direction of targets but not distance.  The UI has numerous
        annoyances like this.  Play time of main mission: 17 hours, 33 minutes.

2/5     An interesting critique of the whole space shuttle program
        written in 1980: http://csua.org/u/8cc
                         \- doesnt this title seem in poor taste?
                            \_ No, selling body parts on ebay is poor taste.
        \_ Hmm. With all due concern for recent events, I'd have to give
           the program more credit for how often the shuttles got through
           the entire business this article describes in one piece. It's the
           stuff they didn't notice or didn't think of that have caused
           problems...But I guess I'll have to wait and see what happened to
           Columbia to say that for sure.
           My closet hope is that this will re-focus the space program on
           earth-observing missions. They cost less than one percent of the
           manned mission costs and have actually tangible benefits. With
           American sentimentality over spaceflight to contend with, though,
           it's a long shot.
        \_ "Even as the Apollo 11 moonship was being primed for what President
           Nixon called "the most important event sine Creation"--the August
           1969 moon landing--plans for a space shuttle were being drafted."
           What?  The landing was JULY 20, 1969
           \_ http://www.gsfc.nasa.gov
        \_ The problem is NASA's monopoly on space.  Boeing, NASA's
           primary contractor is a vertically / horizontally integrated
           behemoth. The industry must be privatized to encourage
           commercial development and innovation.

1/6     Is there any manufacturer that sells dishwashers that have glass or
        plastic see-through doors?  I saw a demo unit of a whirlpool
        dishwasher at Best Buy where all four sides are see-through, but I
        haven't see any retail ones.  Thanks.
        \_ your English sucks.
           \_ Your capitalization sucks, like yer mom.
           \_ Did he ask for a grammar critique?
              \_ No. Are you a moron?
        \_ real men do the dishes BY HAND.  You use less enery and also
           less water. water is life, please don't waste it.
           \_ Real Men use an autoclave. --dim
           \_ According to PG&E, dishwashers use both less water and less
              heating energy than hand-washing if you wash full-loads.  I
              don't use my dishwasher because my wife doesn't want the dirty
              dishes to sit there for a week before I accumulate a full load.
              (Yeah you can ask why I'd listen to a bankrupt company.)
              (Yeah you can ask why I'd listen to a bankrupt company.)  On the
              other hand, I conserve water by using a front-load washing
              machine, putting water bags in my toilet tanks, turning off
              the tap while brusing or applying shampoo or soap, and going to
              a carwash which recycles water instead of washing my car on the
              driveway.  The only other thing I didn't do is not watering the
              lawn at all and let all the grass die.  That would save the most
              water, but my wife would kill me.

                 \_ Need to get the salt off.
                 \_ Because there are times when it doesn't rain for several
                    months.
              \_ There are many ways of hand-washing.

                 in this state residential use accounts for 8% of all water
                 use.  farming in the fucking desert accounts for the other
                 92%.  we're 25% over our take from the colorado.  if every
                 person in the state stopped using water for all non-farming
                 uses, we'd still be overusing our draw on the colorado.
                 you're wasting your time and annoying your wife.
        \_ Found one googling for "dishwasher transparent door"
           It's a countertop one for four placesettings.
        \_ Yes, there is.  I saw a demo unit of a whirlpool dishwasher at Best
           Buy where all four sides are see-through, and I was smart enough to
           ask the salesdrone about a retail version.  Salesdrone was more than

           consumer level devices.  They shouldn't require special cooling
           units, water pumps, super quiet extra expensive fans, etc.  I've
           decided the whole thing is a big scam and I'm not going to toss
           away good money on the computer version of Rice Boy Rocketry. --!RBR
           \_ the quiet fans from pcpowercooling are about the same price
              as you'd pay for a loud, generic fan you'd find at compusa
           \_ A while back our work had a power outage.  It was amazing how
              much quieter the office was without all those computers on.
              Ever since I have been a believer in quiet computer case design.
           \_ Lots of people find that even non-overclocked are still very
              noisy, so this question is still relevant.
              \_ That's the point I was trying to make.  Why the hell are
                 computers so god damned loud and hot in the first place?

                          "Oh, that won't work for _me_." My iMac runs
                          all the software I want. It's also really
                          quiet -- no fan.
           \_ I was working on my laptop with its disk spun down and the fan
               off. It was nice to not hear the incessant racket.
           \_ I actually find our PVR/satellite receiver to be annoyingly loud.

        an oily layer at the top.  Anybody know what causes this?  oktnx
        \_ film from soap or something left in the cup/glass?

        \_ moron, you can't superheat water without pressurize it

        \_ it's just the oils within the tea.
           \_ It's filtered tap water (no tea yet) and I never see it
              except when the water is very hot and not boiling.
                \_ Are you interested in BS speculative answers?
                   \_ Definitely.  It's a slow day.

                           a thin layer of very hot water.
                           Alternately, maybe it IS oil, but it was oil
                           that was sort of embedded in your teacup, and
                           didn't float to the top until things got very hot.

        One question on everyone's mind was whether the light actually
        got dimmer, so resourceful Daily Californian photographers Ian
        Buchanan and Robert Katzer took light readings near the peak of

        the eclipse but only 1/640 half an hour later -- proving that the

                    had it filled with cement(they were just finishing up

12/28   Probably a longshot but I'll ask anyway.  Anybody have experience
        digging for groundwater?  And also with septic tanks?  I'm considering
        building in an area without running water or sewage lines.  I'm
        wondering how much it costs, any gotchas, etc.  Thanks.
        \_ Had this when I lived on the east coast.  It sucked.  Sometimes
           we'd run out of water.  Other times the water would freeze down
           to a trickle.  And getting the septic tank cleaned was a good day
           to be somewhere else.
        \_ Big gotchas are how deep you need to drill to get water, what
           type of rock/soil you're digging through, water quality (ie.
           what you need to do to make it potable), water table level
           changes, and a backup pump when you lose electricity. The septic
           tank can be a bother, but as long as you follow city/state
           building regs (or even expand on them) you should be okay. You
           can get away with getting it cleaned fairly infrequently. Plus
           remember that the toilet is no longer your trash can....
        \_ Thanks.  How about cisterns?  Did either of you had cisterns
           installed?  I'm thinking of putting in these tanks to hold water
           for irrigation.  Man this is a lot of trouble.  Maybe I should

                   \_ Which means there isn't much more conserving to be done.

                      blood from a rock.
                      \_ Not necessarily.  It *could* mean that we can cut back
                         even more on heating and cooling given the relatively
                         mild climate, as long as we are willing to tolerate
                         a bigger temperature range with our bodies.  Just set
                         back your thermostats a little, and turn it off when
                         you're not there.  Also turn off the monitors and
                         lights when you leave your office.  All are just
                         simple easy steps.  I have a friend who lives alone in
                         a 2400sq ft house in Santa Clara.  He leaves his AC on
                         24hrs/day.  I asked him why he doesn't turn it off
                         when he goes to work to try to conserve, and he said
                         "oh, because electricity is cheap."
                         \_ This simply means he isn't paying what the power
                            really costs.  Ask him again at the end of July
                            when he sees that month's bill how cheap his power
                            is after the next rate increase.  Anyway, your one
                            friend is hardly representitive of the average CA

                            one side.  Yes, people should not waste power on
                            stuff (like turn off the lights when you leave a
                            room, duh), however we should be increasing supply
                            as well.  Note that a lot of the problem is that
                            the so-called de-regulation (it wasn't) disallowed
                            the signing of long term low cost power contracts
                            so pg&e and sdge(?) got stuck buying spot power at

3/21    Does the water get hotter faster if you open the faucet more?
        \_Ever hear of 'empirical' data? try it at home.
        \_ yes because you remove the cold water in the pipes and
           fill the pipes with the hot water from the heater faster if
           you open the valve more.
           [ the indenter was here ]
              in the pipe which means it losses less heat to the pipe and the
              surrounding.
           \_ Plus the water should also be hotter, because it spend less time
              in the pipe which means it loses less heat to the pipe and the
              surrounding.  (That's assuming you have a huge heater that can
              keep up with the consumption.)
             \_ yes, but since the water is in laminar flow, there is still
             cold water hugging the pipes so the water isn't completely
            hot until heat is transfered to the cold water hugging the pipes
            so it will take some more time.
                \_ Nonsense.  The slower flow is laminar too, and if at
                   faster speeds the flow becomes turbulent, your whole
                   bullshit argument is blown out of the water.
                  \_ the reynolds number is too low for turbulance and
                 and is mostly based on velocity:
                reynolds number = diameter * velocity / kinesmatic viscosity
                only turbulance would occur at fittings .etc. but in general
                In a pipe, water in contact with the pipe moves slower than
                water in the middle of the pipe.
                  \_ Regardless of whether the flow is laminar or turbulent,
                     the water, even at the EDGES, flows quicker if you
                     increase the flow, so it'll heat faster.
                    \_umm. definition of laminar is velocity = 0 at edge
                        \_ umm. definition of edge -> infinitesimal width

           \_ Can the foam keep the water inside the pipes warm for eight
              hours or so?  E.g. when I turn on the faucet in the morning, is
              the stale water still hot?

        \_ Shuttle is much more expensive than other launch systems,
           say US-built unmanned rockets, largely because it's manned.
           By unmanned standards, the Shuttle is highly reliable
           -- one failure in over 100 launches.  Proton is cheaper
           than US rockets not only because of low labor costs,
           but because they're designed very robustly.  With US rockets,
           you build the rocket just slightly better than it needs to be,
           then do a shitload of analysis to prove that it works.  In
           the Soviet Union, you make it on the whole more robust,
           and if it fails, you don't worry as much about it, and build
           another one.  I would consider Soviet aerospace industry

           aerospace is just about the only sector of their economy

        \_ I thought Willie and Jerry nixed this plan.
        The western span looks like a normal suspension bridge but what's
        with the eastern span?  Wasn't the whole premise of the bridge
        redesign to make it more earthquake proof.  I thought the old
        bridge collapsed during the World Series earthquake because it
        wasn't a suspension bridge but a regular type.  So why is 1/3
        of the eastern span supported on cable stays but the other 2/3
        not.  And why is there a bend in the bridge.  What's the point

           what the metal joints that make your car go clickety-clack are for.
           Regarding the bridge types, I seem to recall from somewhere that
           the western span was build as a suspension bridge, since it needed
           to be high enough for large ships to pass under, and that such a
           structure is the type that can be that high and long and still be
           flexible enough to withstand wind and quakes and stuff.  The other
           part is that the water under the East span is shallower, so they
           could sink more supports into it--look at a cross section of the

        in all kinds of tree that'll be great too.  HomeDepot's selection is

        \_ I'm no RF expert so I never understood why higher frequency

           \_ E =hv ??? more energies?
              \_ you're confusing equations. this is for a single particle. you
                 can transmit a 10khz signal and give it just as much energy
                 as a 10Mhz signal by uppingthe amplitude (or the intensity,
                 if you like particles). i'm no RF expert either, but I think
                 the answer is that wavelengths get interference from objects
                 of similar size. there are lots of large obstacles, so low
                 frequencies don't perform well, and there are lots of very
                 tiny obstacles, so light and doesn't do well, but somewhere

                 \_ Stupid fuzzy universe.  Why wasn't Planck's constant set
                    to 0, damn it!
                 \_ ali, or someone else with clue, please explain to me
                    why IR tends to bounce around, but microwave is
                    directional
                    \_ AFAIK, it is just as ali said--that is, your wall will
                       absorb and re-emit the IR.  IR is very close to the
                       visible spectrum in wavelength whereas microwave further
                       away.  The physical transitions for visible and infrared
                       are similar, whereas microwave is different.  Hence
                       materials that reflect visible light will likely reflect
                       infrared the same or nearly the same way.  See
                       http://www.scimedia.com/chem-ed/light/em-spec.htm for a
                       spectral breakdown. -emarkp
                       \_ Huh?  All you said was that IR is like visible
                          and microwave is different.  Why does IR tend
                          to bounce around, but microwave tend to be
                          directional?
                          \_ It bounces around for the same reason that visible
                             light bounces around.  Absorption and reemission.
                             \_ Now what about microwaves?
                                \_ Microwaves are caused by molecular rotations,
                                   instead of electron level jumps.  That's why
                                   it makes stuff hot--it rotates/vibrates water
                                   molecules, and the friction warms up the
                                   food.  Broadcast microwaves have shorter
                                   wavelengths yet and ignore most atmospheric
                                   matter.  Since the matter (in the air or in
                                   your wall) isn't the right size to absorb the
                                   energy, it just goes right on by.
                 \_ Different wavelengths definetly have different absorption
                    and reflection properties.  However, I don't think
                    a 2.4 GHz signal has a longer range because of less
                    reflection/absorption.  A 2.4 GHz can bounce off
                    walls and buildings pretty easily.  One possible reason
                    for the longer range of a 2.4 GHz signal could be higher
                    bandwidth.  I think the FCC allows 80 Mhz of bandwidth
                    for 2.4 GHz signals, but don't know the numbers for
                    other frequencies.  Also there might be less interference
                    in the 2.4 GHz band than in other bands.  -emin
                    \_ what does it mean by "80Mhz of bandwidth for 2.4
                     GHz signals?  and why does microwave oven need to
                     shield the microwave from escaping while cell phone
                     uses signal in microwave region "openly"?
                     \_ Because microwaves in an 'oven' are specifically
                        tuned to vibrate water, which is in most living
                        things. But cellphone radiation supposedly is
                        on frequencies that do not affect living things.
                        Yeah, right.
                     \_ Well I'm no microwave expert but I'd say that
                        your roommate's parrot would heat a lot less quickly
                        with microwaves leaking out of your microwave
                        instead of reflecting inside.
                    \_ it means that you can transmit more signal per channel,
                       which means that you can use a higher bandwidth
                       modulation technique which is more robust to noise.
                       i think emin is actually right, and it has nothing
                       to do with reflections and transmissions. it's more
                       likely a bandwidth issue. -ali

           filtered water and the unfiltered one taste bad and there's not
           much difference.
           \_ Well, look on the bright side, at least Fremont is much more
              expensive than Oakland or Berkeley..  Hmm, wait...

9/15    What consumes more power, an empty refrigerator or
        a full refrigerator?
        \_ on startup from an unpowered condition, the full one does
           because you need to cool down a larger amount of stuff
           (most solids/liquids have a higher spec.heat than air)
           but say you have everything cooled down, a sort of steady
           state and you pull the power, then the full fridge will
           stay cooler longer due to the higher "heat mass"  One could
           similarly say that the full fridge requires less energy per
           unit time to maintain a low temperature as all the frozen
           veggies and meat and other things with high water content
           maintain their temperature much better than air.  Of course,
           if you dont plug either fridge in at all, then its a tie,
           though in a strict sense the full one will absorb more heat
           but will give up less heat given a rise or drop in temp. --jon

        \_ how often one opens and closes a refrigerator really affects how
           much power it uses, more than how much it contains.

        to go to the moon gave a tremendous push to computer technology.
        Is this true?

           Apollo workstations, which were (as you can probably guess from the

           control workstations developed for the unprecedented computing
           demands of the moon mission.  Apollo Computer was a public
           corporation run by NASA as a technology-transfer testbed until the

                   sell workstations & the inventor of the workstation market,
                   which they dominated for years until Sun finally caught up.
                   \_ Wait... so those Apollos weren't running OS/2 afterall?
                \_ Apollo was the first company to sell workstations and
                   basically created the workstation market, which they
                   dominated for years until Sun finally caught up.
                   \_ Oh, I once thought Sun was the first.  Never mind.
                        \_ Sun was the first UNIX workstation.  Apollo used
                                their own multics-based OS at first and added
                                a UNIX layer to it after they started losing
                                sales to Sun.
           \_ The Apollo DN4500 had a secret hidden switch (activated by a
              special key which could only be legally posessed by NASA
              employees and members of the UN "black helicopter" multinational
              response team) that, when flipped, upped its processing power to
              approximately that of a Cray Y-XMP.  Pretty snappy for a 1980s
              desktop machine.
                \_ The real reason Soda Mk I died was a booby trap set to
                   destroy the motherboard triggered when CSUA'ers decided
                   to try and activate this switch.
        \_ The government poured billions into the Apollo program not just
           so we could get stupid pride over "beating the russians" but to
           help finance major improvements in all sorts of technologies.
           \_ Little does the public know about the truth behind the "Space
              Race"... in fact, the United States waged war in space
              against the Russians until the late '70s when the 19th
              Stellar Fleet and the Russian 4th Fleet were destroyed by
              some unknown force.
              \_ Mojo Riser?
                \_ Tom is a patriot.  He was on the ground out of rotation
                   when the 19th was burned from the skies around Io.  Now
                   commander of the 32nd, Tom is burning both Russians and
                   the Alien Menace from space on a daily basis.  Quoted
                   recently in Space Marines (issue 5, vol 3), Tom says,
                   "We're going to doosh those bastards til there's nothing
                   left to doosh and then we're going to doosh 'em some more!
                   SB+25 at Rom!"  -tom #1 Fan

1/20    What the fuck is Nasa wasting money sending John Glenn
        into the orbit again?
        \_ To study the effect of old men having heart attack in space?
        \_ To see how much more sex urge an old man has in space?
        \_ Give it to me!  Give it to me!
           \_ the money or John Glenn?
                \_ The heart attack.

5/1     Support supersonic transport! If one thought the Concorde was an
        awsome display of technology, wait until one sees what NASA has to
        offer now.
        \_ Space Shuttle Challenger?
        \_ The Concorde was an awesome display of government hubris.  There's
           a REASON it's on the cover of a book called "Great Planning
           Disasters."

        In article <gwh-forger-j773@agate.berkeley.edu> you write:

        >along hot and cold water copper plumbing.

        Could you elaborate on this?  Do you actually mean that they
        used the pipes as signal wires?
