Do you know what $$\infty$$ means? Want to learn some math they won't teach you in high school? We'll talk about sets, how to count numbers, different kinds of infinity, and a thing called Hilbert's Hotel.

Geologists are happy people and you can be one too! We'll talk about rocks and the structure of the Earth and see some cool maps. Did you know that ancient volcanoes are buried under Massachusetts?

The Supreme Court makes a lot of news. Did you know you can skip the news blurbs and read argument transcripts and legal orders yourself? We'll give a quick overview of the American justice system and discuss some key branches of the law. Then we'll jump in and look at some decisions!

Geologists are happy people and you can be one too! We'll show some cool rock samples from New England and beyond and talk about why silicates, carbonates, and halides make the kinds of materials they do. We'll also discuss the Earth's formation. Did you know the core is made of iron because iron is heavy and it sunk to the center?! Obligatory joke: rock on!

Public transportation: subways, buses, ferries, trolleys, railroads. But also paratransit, bicycle sharing, and commuter vans. We'll discuss case studies of recent failures: Boston's Green Line Extension, the Washington Metro, and the Bay Area BART system. Our question: what is transit today, and what should it be? We'll see a brief history of public transportation in America, its financing, and the origin of the word "commuter."

Always wanted to do computer programming, but didn't know how to get started? We'll learn how to think the way computers do. Then we'll program some cool graphics/animation programs in Processing. Not for you if you have substantial programming experience.

Ever leave an art museum feeling like you didn't see anything cool? Fact: if you know more about how people have cranked out art through the centuries, then you'll notice more about it. We'll do some drawing exercises and take a whirlwind tour of art over the last thousand years.

Computers, in theory but not in practice.

Learn how to play Mao! (It's a card game.) When we say you have to learn how to play the game, we really mean you have to learn it. We won't be giving you any of the rules! For the full experience of Mao, please don't go and search up the rules before coming to class. That just spoils the fun. Don't worry though; at the end you'll take back a sheet containing the basic rules, so even if you haven't figured out the rules by then, you' know how to play the game.

How many bubbles are there in a bubble bath? How many carbon atoms in a person? Learn the basics of Fermi Questions, then test your powers of estimation in the Fermi Derby!

Ever leave an art museum feeling like you didn't see anything cool? Fact: if you know more about how people have cranked out art through the centuries (yes, at multiple times in history that's a pretty accurate description), then you'll notice more about it. We'll do some drawing exercises and take a whirlwind tour of art over the last thousand years.
