The information density is incredible. A 2x2 matrix (Jordan constants) containing enough information to produce a slice of a hyperbolic paraboloid. Leaves me mesmerized...

It's funny, at the end of each lecture I just want to yell... "NO! Don't stop! I must see how this ends!"

Very similar to when I stop our children's movie and tell them to go take a bath.

I guess nobody knows all of math and it is constantly a learning process, but things like "Jordan constants" which defines proper nouns to thousands upon thousands of math concepts, symbols, theorems and approaches just makes it a even harder to memorize the whole shebang. Fascinating but sometimes overly complex.
