Do you use the Internet? Own a smartphone? Every click you make and step you take produces data about you, much of which can paint a very personal picture of your life. This data is stored and used by many organizations, both governments and companies, some of which you probably don't even know the names of. In this class, you'll learn what data exists about you and what it says about you. We'll discuss what privacy means in today's age.

Attracted to acoustics? Disinterested in the treble clef? Then this class is for you! Get a crash course in the science of sound. Most examples will involve the lower end of the frequency spectrum.

Step 1: Get teachers. Step 2: Get students. Step 3: ??? Step 4: SPLASH! Want to know what the ”???” is? Come find out how we make Splash happen! Presented by the directors of several past Splashes.

Steer yourself on over! We'll give you a tour of the cow from head to tail and show you how to cook (and eat) it all. We'll moove from the science of preparing meat to useful tools and techniques for preparing beef. Well-done classes are rare, so it would be a missteak to miss this one. Lots of delicious beef will be served.

Want to try a different type of exercise? Ever considered joining the track team but never had the time? Then this class is for you! Hit the ground running at Spark, quite literally, with a 5K race--that's 5 kilometers long, or about 3.1 miles. The race is open to anyone, whether you run high-altitude ultramarathons backwards or you still can't tie your sneakers. One important thing: This class moves very quickly, and it will be easy to fall behind. Show up on time--if you're late, it could be very difficult to catch up.

Writing computer programs is easy. Writing secure programs is not. Through demonstrations and real-life stories, we'll explore the ways in which computer systems break, and discuss what security means to the Internet as a whole. Take this class to learn what "cybersecurity" is all about!

Learn to code with an application you already know!! We will cover using message boxes to interact with the user, take in data,and automate data manipulation and formatting. Intended for complete beginners, but can benefit anyone. The language is Visual Basic for Applications.

Like ice cream? Watch us make it using liquid nitrogen, and learn about some cool properties of LN2 along the way. Served steaming cold!

9000? The number of atoms in the universe? A <a href="http://en.wikipedia.org/wiki/Googolplex">googolplex</a>? Those are tiny. You'll learn how to write down numbers bigger than you've ever dreamed of--some so large that they're uncomputable.

Steer yourself on over! By the end of this class, you'll have learned how to cook (and eat!) a perfect steak. We'll moove from the science of cooking meat to useful tools and techniques for preparing beef. Classes this well done are rare, so it would be a missteak to miss this.

Why is your tap water safe to drink? How do we protect the environment from our sewage? What happens to all of the rain after a storm? Where does your water come from, anyway, and how will we manage it in a world in which it's more scarce? Come learn about the past, present, and future of water and sewage, from Ancient Rome to California.

Why is the South African national anthem so hard to sing? What has caused conflict and bloodshed around the world since the French Revolution? And why, when watching the Olympics, do we cheer for Americans we've never met from places we've never visited? In this class, we'll learn what a nation is-- it's not the same as a state or country--and why it's important. Then we'll explore how different nations see themselves by listening to some national anthems.

Learn about current developments across math, science, and computing! Every week, a different guest speaker will talk about their current research. Find out some of the cool things that MIT students spend their time working on.

Want to learn how to keep secrets from your little sister or a well-funded intelligence agency? Why the last digit of $$7^{7^{7^{7^7}}}$$ is $$3$$, or what's wrong with the number $$37$$? How to count to infinity, and then some? Then sign up for this whirlwind tour of math! You'll learn about something completely different each week from a series of 7 speakers. The exact list of topics is TBD and may depend on class interests.

A puzzle is a problem that somehow has a word or short phrase as an answer. The puzzle can come in many forms, including a list of clues, a page of images, and a bag of broken pasta. There are usually no instructions: it's up to the cleverness of the solver to figure out how to get to an answer. In this class, you'll learn how puzzles work and get practice solving them!

Steer yourself on over! By the end of this class, you'll have herd how to cook a delicious prime steak. We'll moove from the science of cooking meat to useful tools and techniques for preparing beef. Classes this well done are rare, so it would be a missteak to miss this.

Learn about current developments across math, science, and computing! Every week, a different guest speaker will talk about their current research.

Topology is geometry without measurements. Learn what it means for functions to be continuous and spaces to be connected or compact. Then find out how this makes proving some well-known theorems easy.

The four color theorem tells us that we can color every country on a map with only four colors, such that no two bordering countries have the same color. It took 140 years to prove. We're going to prove the 5-color theorem instead! We'll learn about graph theory and draw lots of pictures.

You and your friend have several piles of Goldfish and alternate turns. When it's your turn, you pick a nonempty pile and eat some Goldfish from it. If all the Goldfish are gone, you lose. Discover how to beat your friends at this game and eat lots of Goldfish in the process!

Here's a math problem that 85% of doctors get wrong: 1% of women at age forty who participate in routine screening have breast cancer. 80% of women with breast cancer will get positive mammographies. 9.6% of women without breast cancer will also get positive mammographies. A woman in this age group had a positive mammography in a routine screening. What is the probability that she actually has breast cancer? Bayes' theorem is an incredibly important result that tells us how to change what we believe based on data. We will learn how to use it to solve this problem and others. We'll also talk about why much of the statistics used in science today is wrong!

Your math teacher has talked about "real numbers." You can add, subtract, multiply, and divide them, or you can put them in order. But you can do those with other sets of numbers, like the rationals, too! Is there an additional property the reals have that makes them really different from any other set? In fact, how do we know the reals exist at all--are they for real? Thankfully, the answer to both of these questions is "yes." We're going to show why by building the reals with our bare hands.

Watch as absurd sentences become absurd pictures, and vice versa!
