Meep's Math Matters 14: Infinity is NOT a number 2: the rationals

[tekn04life]

this is so good! everyone's brain works differently but it finally clicked after watching your first 2 videos. can't wait to see the rest of them! is this set theory or number theory or what?

When you are trying to say something about how many elements are in a set (which is what I'm doing here), it's essentially set theory.

That said, it's not as if all mathematical areas are clearly defined with no overlap -- of course, there's =lots= of overlap. Once a person gets into uncountable infinity, you start getting into real analysis.

I think it's more helpful to think of math as a whole, and not as a bunch of disconnected bits. Don't get hung up on the name.
