Beyond the Third Dimension: Chapter 7

Maybe it's because of spring fever or the full moon, but I had a hard time grasping the finer points of this chapter. I did enjoy the fact that it had practical applications, though. It was comforting to see that one of my professors from last semester (Gould) and even a choreographer could find a use for dimensionality.

I also liked that the issue of time as a fourth dimension was addressed, although I'm not sure I understood the real difference between a geometrical fourth dimension and one that acts like time (something about subtraction in the pythagorean theorem?)

Perhaps I will try to write more when I feel less looney and we've discussed matters a bit more.
