Educational Physics Simulations

Physics you can feel

Every topic starts as a story with a question. You call it, the real physics runs, and the moments that surprise you are the ones that stay.

How it works

Start with a story. End with the click.

01 · Predict
You call it
Before anything moves, you pick. Not a guess. A committed position on what the physics will do, locked before the world runs.
02 · First Run
The world runs
One button. Your prediction stays visible on screen. The sim runs exactly what physics says, not what you expected.
03 · The click
It stays with you
The moment the physics settles it, one way or the other, becomes yours. That event is the memory the concept rides on.
