Computer science
Learn select topics from computer science - algorithms (how we solve common problems in computer science and measure the efficiency of our solutions), cryptography (how we protect secret information), and information theory (how we encode and compress information).
Did you know? You can learn how to program
on Khan Academy and create your own programs.

computer programming
subject to get started.
Algorithms
We've partnered with Dartmouth college professors Tom Cormen and Devin Balkcom to teach introductory computer science algorithms, including searching, sorting, recursion, and graph theory. Learn with a combination of articles, visualizations, quizzes, and coding challenges.
Journey into cryptography
How have humans protected their secret messages through history? What has changed today?
Journey into information theory
We've always been communicating.... as we moved from signal fires, to alphabets & electricity the problems remained the same.
Internet 101
Thanks to our partners at Code.org, you can learn how the internet works - everything from WiFi and IP addresses to cybersecurity and crime.
