What aspects of the real world involve chance? What does mathematical probability tell about about those aspects? What concepts from mathematical probability can be illustrated by interesting contemporary real data? This web site records my efforts to articulate some answers to such questions. It is aimed at readers who have either read some “popular science” style account of probability, or taken a college course involving probability. So I won’t explain very basic stuff, and I mostly avoid discussing material easily found elsewhere.
