Special Seminar: Paradoxes and Infinity

In this class we'll explore several popular paradoxes and attempt to wrap our brains around the world of infinity. For example, we'll discover a hotel that's never full: somehow, this hotel can always add another guest, or two, or three. We'll also run into paradoxes about goats, haystacks, pop-quizzes and more. If you're interested in mind-bending ideas and theories and have a background in basic algebra, this class is for you!

This class dramatically enhanced my ability to solve Olympiad-level geometry problems, as well as my problem solving skills in general. The instruction was some of the best I've ever seen. Not only did the class explain the techniques for solving various problems, but it also gave the motivation for thinking of a particular technique for a problem. I can now complete problems that used to take me weeks to solve in a couple hours!
