We all have down days but what if all of your days are down? Why do some people have difficulty with their daily activities just because of their brain? This class explores some of the science of depression and the human aspect of what to do if you or a friend is having trouble.

Does a set of all sets exist? How can we define numbers using only sets? Are all the elements of the empty set tap-dancing elephants? How big is infinity? We will discuss the foundations of math with axiomatic set theory, and motivating examples, including Russel's Paradox, vacuous truth, the Banach-Tarski Theorem, and the Axiom of Choice. Given time, we will also discuss some issues with the usual model of sets, ZFC.
