I love calculus too!
Math is fun, one of my favorite things is when I learn something that I had always been taught was true turns out to not be true.

For instance:

(0) x (X) = 1 , what does X equal? There IS an answer. It turns out that not everything multiplied by zero equals zero.

Here's another one:

I had always been taught in calculus that the derivative of a discontinuity is 'undefined'. It turns out that isn't exactly true either.

10 e-donuts to whomever can answer either of the above!

HINT: They're both related.

In my opinion "real" math ends when you can understand Maxwell's equations using 3-dimensional vector calculus. Everything after that is just mental masturbation.

Prove it. :) ... seriously.
