In this class we learn about several of the most important topics in cryptography, including: - encryption, private-key and public-key encryption - MACs - zero-knowledge - differential privacy This course is unique in that it doesn't require advanced math and computer science knowledge beforehand, because for each concept, we will use real-life puzzles. Afterwards, we will learn the actual computer science versions, introducing basic concepts from modular arithmetic and complexity theory. Most importantly this is a PROBLEM SOLVING CLASS-- we will solve problems together in class, and you will be expected to contribute and participate.

Sign languages are sophisticated, natural, full-fledged languages that are entirely visual. Though there are many sign languages in the world, American Sign Language (ASL) is the native language to Deaf people and their families in North America. I have a lot of experience teaching ASL. After this class you'll know the basics of ASL, including the manual alphabet, basic sentence structure, and enough vocabulary and patterns to introduce yourself, ask/answer questions, and a base for continuing to learn sign. Learning sign language is EXTREMELY fun. You're not just learning a language, but you're learning how to think and communicate VISUALLY in a completely different language. There's no talking at all in this class- from the second you walk in, we will be signing and communicating visually. You may have never experienced a setting like this, so embrace the challenge. Shut off your ears, open yours eyes, and focus on thinking and communicating visually. Please learn the manual alphabet BEFORE class. We'll go over it quickly, but it is important that you learn the manual alphabet BEFORE coming to class so that we have time to learn the actual language and talk to each other in it!
