2009/12/2-9 [Science/Physics] UID:53557 Activity:nil | 12/2 Looking for a "LHC and Higgs bosom for Dummies" equivalent site.
I'd like to learn more but most sites out there are just way
beyond me. Is there a dummy's version for it?
\_ W = weak force, EM = electromagnetic force, S = strong force,
G = gravity. They're the four forces, and the holy grail of
physics is to unify them all in a single theory -- the Grand

2007/5/29-6/3 [Science/GlobalWarming] UID:46783 Activity:moderate | 5/29 Global Warming: It's not just a prediction anymore!
\_ It's not. I was shocked to see tangible effects when I was
in S. America last year. Most people will also confirm pretty
drastic climate change over the last few years there. -John
\_ Climate changes. That is not in dispute. The issue is if the
climate is changing mostly to due human activity or if it is

2006/5/11-17 [Science/Physics] UID:43023 Activity:nil | 5/11 Physics question. Why doesn't the Weak Nuclear Force fall off
inversely proprotionally to the square of distance?
\- Oh hello, this is a good question and "why is the weak force not
like the em force or gravity" is one of the great results of
THE STANDARD MODEL. I am going to assume you have taken a little
bit of quantum mechantics but not quantum field theory, so this

2005/9/22-23 [Science/Disaster, Science/GlobalWarming] UID:39815 Activity:moderate | 9/22 Question for motd:
A day ago I think there was a link explaining the downsides of
using a nuclear bomb to try to disperse forming hurricanes/tropical
storms. I have two questions, does a thermonuclear (fusion) bomb
have the same fallout effects as a nuclear bomb, and two, if not,
wouldn't it be a great solution to the problem? Just go nuke these

Ok can some physics person explain this:
"the light signal travelled faster than 300 million meters a
second. And even though this seems to violate all sorts of cherished
physical assumptions, Einstein needn't move over -- relativity isn't
called into question, because only a portion of the signal is affected"

2005/8/20-22 [Science/Physics] UID:39203 Activity:nil | 8/19 [ Thread deleted out of frustration. I can't seem to explain my
own question, so people just show up to chew the fat about QM.
Not a single person gave me an account of what an 'observation'
exactly is. I know what the slit experiment is. I know what all
the conventional interpretations of QM say. Doesn't it bother anybody
that the standard interpretation of QM is based on an apparently

2005/8/10-13 [Science/Space, Science/GlobalWarming] UID:39088 Activity:low | 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
