I once sat down and tried to read about Category Theory. I got almost
nowhere though; I cannot for the life of my figure out how the
definition of "category" is actually different from the definition of
"set". Or how a "functor" is any different than a "function". Or...
actually, none of it made sense.
It didn't sound terribly interesting anyway. I'll stick to group theory...
