Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Well, where do you think I got this stuff from? You think I invented it?
  • "A lot of quantum mechanics" omits squaring the result to get a probability.
  • There are more Rigs that just the nonnegative reals, basically subsets (closed under addition and multiplication) of matrices with nonnegative real entries.
  • No, I intend to say that the mathematical structure of flow in networks, of minimal paths in networks, of statistical mechanics at finite and zero temperature, and quantum mechanics, is that of combinatorics on Rigs.
  • I have no idea whether complex numbers are necessary for quantum mechanics, but given their algebraic completeness once you have characteristic zero you might as well assume your Rig consists of matrices with complex entries. I guess, for convenience.
  • Where do you keep reading about mathematical structures you can't remotely claim to understand?
  • There will always be people who identify with her over the other candidates.
BTW, did you get my e-mail?

It'd be nice if the battle were only against the right wingers, not half of the left on top of that — François in Paris
