Welcome to CS22!

CS22 is all about giving you the tools to solve interesting problems. You will learn to see the world differently, no longer accepting what is presented to you but instead questioning, building and exploring. Ever wanted to construct a solid, bullet-proof argument? Felt the need to count really large things? Wondered about the math behind spam filters and RSA cryptography? If so, join us in a looney adventure as we dive into Probability, Combinatorics, Logic, Graph Theory and more!

Class will be held in Metcalf Auditorium from 9:00am to 9:50am on Monday, Wednesday, and Friday. You can learn more about the course in the missive.

That's all, folks!

The course missive has been updated to reflect all of this information.

Feb 1 - Highly Recommend Reading on Writing Good Proofs

Homework in CS 22 will become increasingly proof-based as the semester progresses, so it's important to work on your proof-writing skills. Here's an excellent guide on how to write good proofs, and why proof-writing is such an important skill: Proof Tips (from the text used at MIT's course 6.042, written by Lehman, Leighton, and Meyer).

Jan 30 - Homework 1

Homework 1 has been released, and you can find it on the Assignments page. Homework is due on Tuesday, Feb 5, by 10 pm in the CS22 handin bin on the second floor of the CIT. Come to hours if you have any questions or concerns!

Jan 28 - Problem Session Location

Problem sessions will be held in the Motorola Auditorium (CIT 165). The first problem session will be held on Thursday, January 31. The same materials will be covered on both Thursday and Sunday, so you will only need to attend one session.
