What is sound? How do our ears hear the information in sound and send it to our brain to be processed into language? And how might we teach a computer to do the same thing? We'll investigate all of this by diving into phonology and phonetics, the study of the audible components of language. We'll explore what sound is, and look at some ways it can be visualized. We'll talk about all of the different sounds that human languages can use, in English and beyond. Finally, we'll look at patterns in sounds by converting them into pictures called spectrograms. With this tool at our disposal, we can investigate how both computer systems and human brains might tackle the problem of speech recognition. Come learn what you never knew you never knew about sounds!

Is that an orchid, or a mantis? What's the difference between a bug and a beetle? Why does EVERYTHING seem to want to pretend to be an ant? Why do bees cooperate with each other like that? Come learn about insects, the fascinating animals with more than a million species on Earth and a majority of ALL the species we know about! This class will present a whirlwind tour of insects of all sorts. You'll learn how each group is related and how to recognize each group's unique features, as well as some random cool examples of camouflage, symbiosis, and parasitism among insects. As we go, you'll apply your newly-learned identification skills to identify insects yourself!

Do you enjoy unraveling logic puzzles, want to learn about other languages, or crave the feeling of a good riddle? Come solve fun problems from the Linguistics Olympiads, NACLO and IOL! A variety of languages, problem styles, and difficulty levels will be provided for you to solve. Logic and reasoning are your main weapon here – no prior linguistics knowledge required!

What can philosophers learn from computer scientists? Even though computer science is an applied discipline, its theoretical foundations are rich and fascinating. For example, many problems are *impossible* to solve by writing a computer program. Why are these problems unsolvable? I'll prove it to you -- and along the way we'll learn some unexpected facts about infinity. In order to talk about computer science formally, we'll learn about Turing machines. We'll decide on what it means for something to be powerful enough to be called a "computer", and we'll investigate whether systems such as Minecraft or the Game of Life make the cut. Finally, we'll discuss some philosophical puzzles and paradoxes relating to the study of minds and machines and artificial intelligence. Come learn about uncomputability, about Turing machines, and about code that loops forever. We will explore the limit of the mathematically possible.

This class will be a blast from the past. Okay, sure, we're traveling back in time to learn about Ancient Egypt. But that's not the only time travel we'll be doing. In this class, we'll also be traveling back in time – to first grade. Imagine that you are a young Ancient Egyptian scribe-to-be, going through the equivalent of Ancient Egyptian elementary school. You need to learn reading, writing, and ... arithmetic. What happens when two separate cultures independently discover the ideas of mathematics? Are there other ways we can multiply numbers, and other ways we can think about decimals and fractions? The answer is yes, and the details are strange and fascinating! Through a variety of hands-on exercises, we will cover how the Ancient Egyptians wrote down their numbers, carried out addition and subtraction, represented multiplication and division, and manipulated fractions. Inspired by the book "Count Like an Egyptian" by David Reimer.

Interested in science fiction, futuristic engineering, artificial intelligence or interplanetary empires? Ever wondered what would happen if people lived forever? What would happen if the world split in two every time you had to make a choice, and both options happened? What would happen if there was a center of time where time stood still? Come read a few of the short stories of Isaac Asimov, one of the most prolific science fiction writers of all time. We'll spend an hour devouring tales of robots, space, and time!

You've got a TI calculator. It does math. Yet, somehow, that's always felt... unsatisfying. Only math? You want it to do more! With only 27 basic variables available to you, TI-BASIC is one of the more Fun(TM) programming languages out there. Yet, with certain tricks, you can wield the awesome power of lists, graphing, matrices, and more in order to write your own programs for any purpose. As an appetizer, we'll cover the basics of TI-BASIC in class. For our main course, we will use the concept of a "stack" in order to implement recursion in your TI calculator. This is the same way recursion is done by code running on real computers! With this tool in hand, our ultimate goal will be to create a program to draw fractals on the calculator's screen. There will be opportunities to write and run code in class -- so if you have a TI calculator, please bring it. If you do not, you can download a TI calculator emulator to your phone (yes, there's an app for that) or to your computer, or you can write code with paper and pencil -- you'll still be able to follow along and learn.

Whether you're new to programming or have experience, we'll help you learn new things and get better! This will be a self-paced programming workshop, where you get to work on whatever you want -- either pursue your own idea, or let us suggest a project. We'll be here to guide you if you get stuck. If you've never programmed before, we'll have suggestions for resources to use to get started. We'll be in a computer lab, but feel free to bring your own laptop (just make sure to keep an eye on it – Splash is hectic, and it's easy to lose things!).
