Voting Theory

November 12 — taught by Adam Dormier

Have you ever heard that you shouldn't vote for a third-party candidate in the US? Why is that? And why doesn't Australia have that problem? Come to think of it, what does it mean (mathematically) to "take a vote?" Join us as we explore a number of different voting systems, learn some mathematical ways to analyze their strengths and shortcomings, and search for a system that is provably, perfectly fair.

Going Far Beyond Infinity

November 19 — taught by Matt Benet

Answer questions like "Is infinity a number?" and "Why can't we divide by zero?". Recommended for students who are curious about how infinity works, puzzling over some popular paradoxes like Hilbert's Hotel, and challenging ourselves with some harder questions in mathematics.

Cryptology Crash Course

November 26 — taught by Stro Palastro

Can you keep a secret? How easy is it to hack my wireless connection? Why do so many websites ask for 2-factor-authentication? What's a cryptocurrency? Come learn the answers to these questions as we survey the history, mathematics, modern impact, and future of secrets. Recommended for all students.

Chemistry Fire Experiments

December 3 — taught by Matt Benet

What is fire, exactly? Why is it usually orange? Could fire be different colors? Can we make fire with different colors at home? Can I set something on fire without damaging it? Watch me and (if your parents allow you to) follow along yourself as we perform 🔥chemistry experiments, and even extinguish the flame we make using chemistry!

The Evolution of Evolution

December 10 — taught by Isabel Mormile

The scientific consensus is that living organisms evolve over time. But how does this process happen? Science's understanding of evolution has also changed over time, thanks to centuries of debate and new discoveries. In our two hours, we'll explore how the theory of evolution... has evolved!

Fair Division

December 17 — taught by Adam Dormier

Everybody always wants the piece of cake with the frosting flower on it, right? We'll try to answer the question of what it means to divide something "fairly," and look at a few strategies for doing so. We recommend this lecture for students who are interested in exactly what it means to be fair.
