7/6     In arithmetic, repeated "plus" is "times", while repeated "times" is
        "to the power".  Is there an operation that stands for repeated "to
        the power"?  My kid asked me and I have no idea.  Thx.
        \- yes, see "up arrow notation". there is a little field of math
           dealing with "rapidly increaseing sequences". from UCB CS you
           may be familar with the POWER of the ACKERMAN FUNCTION for example.
           you also may be interested in RAMSEY THEORY but that is beyond the
           scope of this motd post. UMESH's ex-student Scott Aaronson has a
           good writeup on the WOB about the constrution large numbers.
           \_ Thanks.  -- OP

12/15   I'm planning on traveling to Europe and I was wondering if there's
        any reason I shouldn't be able to use a US power tap/strip (no surge
        suppression) with just a plug adaptor (i.e., no voltage conversion).
        This would be for use with electronics that accept 100V-240V. While
        the power strip is intended for use at 120V, it's just wires, right?
        (Also, this power strip has no power LED or similar.) If anything,

11/6    Four more years!
        \_ Yay! I look forward to 4 more years of doing absolutely nothing.
           It's a much better outcome than the alternative, which is 4 years
           of regress.
           \_ Can't argue with that.

8/29    OC turning liberal, maybe there is hope for CA afterall:
        http://www.nytimes.com/2010/08/30/us/politics/30orange.html
        \_ and the state is slowly turning conservative. Meg 2010!
           \_ We will see. Seems unlikely.
        \_ Yeah, because CA sure has a problem with not enough dems in power!
           If only dems had been running the state for the last 40 years!

2/20    Ok serious question, NOT political.  This is straight up procedural.
        Has it been declared that we didn't find WMD in iraq? (think so).
        So why did we go into iraq (what was the gain), and if nobody really
        knows, why is nobody looking for the reason?
        \_ Political stability, military strategy (Iran), and to prevent
           Saddam from financing terrorism.
