Mathematics has profoundly changed our world, from the way we communicate with each other and

listen to music, to banking and computers. This course is designed for those without college

mathematics who want to understand the mathematical concepts behind important modern applications.

The course consists of individual modules, each focusing on a particular application (e.g., digital

music, sending secure emails, and using statistics to explain, or hide, facts). The emphasis is on

ideas, not on sophisticated mathematical techniques, but there will be substantial problem-set

requirements. Students will learn by doing simple examples.

In past semesters there have been modules on the following topics:

- Cryptography
- Error correction & compression
- Probability & Statistics
- Birth, Growth, Death & Chaos
- Graph Theory
- Voting & Social Choice
