Research a mainstream Computer Science concept (for example, artificial intelligence, Algorithms, cryptography, programming languages, etc.), then write a Medium post that explains what your learned to a mainstream audience. Browse Medium and choose an article of interest to get a sense of how Medium posts are written: The most insightful stories about Computer Science - Medium (Note: This link can be found in the Activities & Assignments section of this module). A strong submission will match the style, scope, and tone of these articles.
