Interactive simulations of real physics
Understand the mechanism. Then hand it to AI.
AI is a sword: decisive in a ninja’s hands, a danger to an amateur’s — the blade is the same. What differs is what the hand already knows. Every lesson here is a working model of a real system you can operate, so that what you bring to AI is deep.
Pick a system
Or follow the reading order →What a lesson is
A mechanism you operate
Not a diagram of the thing — the thing. Move a parameter and watch the system react, including into the states where the usual advice stops working.
Built around one wrong belief
Every lesson names the specific misconception it exists to delete. The expensive bugs are not in what engineers find hard; they are in what engineers are sure they already understand.
Checked against the source
Claims are verified against the project’s code, RFCs and papers, and every number in the prose is produced by the simulation on the page. Lessons that turn out wrong come down.
