Coho Course #6, A Quick Detour Into Combinatorics

We take a brief break from set theory to explore some fundamental concepts in Combinatorics – the art of counting things.  We'll get back on the set theory train in...

Coho Course #5, Russell's Paradox

Our most exciting stop so far on our mathematical journey! We've already gotten far enough to see – completely rigorously – the infamous Russell's Paradox that had the math world shook...

Coho Course #4, Sets Part 4

One of the most interesting realizations in set theory is that sets themselves are things, and can therefore be elements of sets – i.e., we can talk about sets of...

Coho Course #3, Sets Part 3

It's time to introduce a very important character in mathematics — the empty set.  Despite its emptiness, this set has many important roles to play.
