Questions about gnuplot and AquaTerm

Filed under: Uncategorized — cjohnson @ 3:45 pm

I’m hoping someone out there can help me understand this:  I want to install gnuplot on my Mac, and I’ve already installed AquaTerm.  I can’t find a binary for gnuplot anywhere, so I’m installing it through MacPorts.  However, in doing so MacPorts is downloading a lot of Xorg stuff, as well as AquaTerm.  Why can’t it use the AquaTerm I already have installed?  Why’s it need all of the Xorg stuff if I already have Apple’s X11 installed?

Quick Questions

Filed under: Uncategorized — cjohnson @ 3:07 pm

toad and I were talking on IRC, and he brought up some questions I don’t know the answers to, so maybe someone reading this can help.

  1. What complete fields are there besides the real line and complex plane?
  2. Is every finite field complete in a metric other than the discrete metric?
  3. What about matrices over a finite field?  Since a matrix is a linear operator we can give it in a norm, but does being in a finite field screw with things?
