Friday night…

…and I’m sitting in a cafe, drinking coffee and trying to understand K-theory. It’s probably a sign that I’m a geek, that this seems to be one of the most wonderful ways possible to spend a Friday night.

Incidentally, since I know there are other geeks out there: Does anyone happen to have a good intuition for Bott periodicity, in any context whatsoever? (Topological K-theory, algebraic K-theory, cohomology, something else…) I’m feeling very stuck in not having a good intuition for why it works.

    sounds like a great way to spend a Friday night. 🙂
    I think, however, that I am going to turn in early tonight since I have no reason (TDS) to stay up late.

    I have no idea what you’re talking about 🙂
    But Chris wants to talk math with you… check your stanford email.

    K’s theory – Don’t make it any harder than it has too be! 0:-)

    Oh, you mean that other K’s theory? 😀

    Hmm… has G developed a K-theory? Does it work reliably? 🙂

    How about:
    There is no system of disorder that K cannot, given necessary time and materials, render into order, often with an indexed inventory and maintenance schema to be employed in case of entropy.

    Odd you should say that… the K-theory I’m buried in is a generalization of Index theory. 🙂
