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!

I really enjoyed the material covered in this class. I not only learned how to do a variety of problems,but also I discovered quicker methods of solving problems I already knew how to do. I also was thrilled by the difficulty on these problems; in most other non-AOPS courses I get problems that I can do in 2 seconds. Another thing I found fantastic is that the course instructors answered all of my problems,questions,and concerns.
