oh cool. I had a professor at Hampshire College (well, I WANTED HIM as a professor but his classes were always full) was a topology nut and I’d read the amazing clippings he posted to his door as I could never get into his classes. [I was going to do quantum mechanics and wanted the topology and fractal studies. Just as well though – took child psychology instead and learned what I wanted on my own through the years without the math tongue emoticon ] Loved wrapping my brain around the things on an intuitive level. Folding in particular I find fascinating even more than torus stuff.
