The Fibonacci sequence is one of the most well-known sequences in mathematics. The way you can generate the sequence is simple, but there is a lot of theory behind the sequence and its terms. In this class, we'll explore some of the properties of the Fibonacci sequence, along with a few spinoff sequences and if time allows, some linearly recursive sequences.

BIG BROTHER IS WATCHING. Governments across the world, tech companies, advertisers, fraudsters, scammers—they're all doing their best to track your every step on the Internet. Some of them want to "increase consumer engagement". Others want to "monitor criminal activity". All of them want to infringe on your Right to Privacy. In this class, you'll learn how to protect your privacy online. You might be surprised at how easy it is to get started. Although we can't guarantee complete freedom from surveillance, by the end of this class, you'll know much, much more than the average Internet user about how to easily and *legally* reclaim your Internet privacy. We'll also send out an extensive list of resources after the class that you can share with friends and family, as well as a free ebook about digital privacy and surveillance!

You're in the palace of an Ancient and Powerful King, and the Master of Knowledge has just asked you an artful riddle to test your worth. You're smart: you deliver an impeccable answer in seconds. Of course, it is but courteous to return the exchange by posing a riddle of your own... oh. You don't know any. Now what? It has to be challenging, but solvable. It has to be majestically poetic, but not cringy. Its lines should resound in the halls and minds of the palace and thrust an irresistibly fascinating mystery upon them. Come learn the Art of Riddling.

Why do musicians like 'thirds', 'fourths', and 'fifths'? Why does the same note played on a violin and a trombone sound so different? Are all pianos secretly out of tune? What is a polyrhythm? How can a trumpet produce all the notes with only three valves? Come learn about the *mathematics of music* behind all these questions. A little bit of music theory and math can go a long way in understanding the structure of music in a totally new way. Expect to do a lot of careful listening as you develop your musical mind!

How do languages evolve? How do we know whether languages are related? What differentiates a language from a dialect? This is a class where we discuss these questions, learn about language study and classification, and see how history, language, and culture work together with each other.

Come sing with the MIT-Wellesley Toons! We'll start with some warmups and fun exercises and learn an entire song by the end of the class. We're an a capella group, which means there are no instruments or accompaniments, just all of our voices (beatboxers welcome!). (The Toons are MIT and Wellesley's only cross-campus a capella group. We're a group of friends that enjoy singing a wide variety of music together.)

Music theory, in our eyes, is a way to understand the structure of music in a totally new way. Come to this class to learn why (secretly) all pianos are out of tune, why musicians care so much about "fifths" and "fourths" and "octaves," why a violin and a flute playing the same note sound different, and some other cool tricks musicians play behind-the-scenes!

Learn about the human eye, how to see stereograms, how to take a look at your own retina, and more! There's a lot going on when you look out at the world and most of it isn't... in plain sight. We will have some eye-opening demos looking at how our eyes work. Come and see!

We’re the MIT-Wellesley Toons! Want to learn how to read and sing an a cappella arrangement, or want to sing a bunch of fun rounds? Come sing and jam with us! No a cappella/singing experience necessary :)

Learn about the human eye, how to see stereograms, and more! Stereograms are 2D images that look 3D with the power of the Magic Eye, after some training and practice. There's a lot going on when you look out at the world and most of it isn't... in plain sight. Our eyes are our primary sense organs and looking at how they work can be... eye-opening. Come and see!

Come sing with the MIT-Wellesley Toons, the only (and best) cross-campus a capella group! We'll be doing fun little songs and rounds that won't take more than 5–10 minutes to learn, so drop by whenever you want. If you enjoy singing (doesn't matter if you're any good at it) this walk-in is for you!

Have you ever wondered what a 'proof' really is? How can you be sure that all of mathematics is 'correct', if all you can use to prove it is more mathematics? Come find out in this class! Together, we'll perform and discuss some math leading up to a famous result known as Gödel's Incompleteness Theorems.

How One Man Broke Math Last Winter" A fast run-through of Gödel's Incompleteness Theorems, including some history, just enough basic math and logic to understand them, an outline of their proofs (they aren't so hard!), and what they *really* mean. Come have your mathematical intuitions knocked askew!
