Group Problems
Random Information
Hyperbolic Angles and Lorentz
Boosts
Some pages of handwritten notes that go through the connection of
hyperbolic angles and hyperbolic rotations to Lorentz
Transformations. These suck. Please don't read them. I'll make
better ones at some point.
GNU Octave
This is a matrix/math/numerical software package that works on
Linux and Unix, and claims to work on Windows with Cygwin. I used to
use Euler
for this sort of thing, but for some reason have decided that the time
has come for me to learn Octave.
Maxima
A free computer algebra program. I am not terribly familiar with
it, but hope to become more familiar with it. All I know is that this
made me happy:
(%i1) integrate(exp(-x^2/2),x,-inf,inf);
(%o1) sqrt(2) sqrt(%pi)
