My problem isn't mathematical or even philosophical as in Curtis' case. I
can do differentials, and integrals with ease, matrix algebra and discrete
logic don't bother me a bit. My problem is I simply don't "get" it. The
intuitive leap that everyone keeps talking about, just doesn't happen. I can
follow the math, I just don't _believe_ it.

Actually the geometric interpretation was somewhat easier to understand.
When I get a little more time on my hands (ha ha), I intend to get Steve,
Timothy and Zenon to help me out here....
