Worth noticing: The stated format moves from a hands-on demo to puzzles, a real problem, and a one-page field card for each idea.

Field notes

The page lays out a consistent learning sequence: a plain-language introduction and demo, practice through games or puzzles, application to a real problem, and a one-page field card. It says each idea takes about 20 minutes across three levels. Five mental models and six philosophical topics are marked ready to play; physics simulations and the current-world systems section are labeled coming soon.
