Turn the knobs. Push it past where it should go. Every simulation here computes real physics — so whatever you try, the answer you get is the one the universe would give you.
Not a topic — a misconception. Each entry below names the specific wrong idea it was built to dismantle, so you can pick the one your class actually needs.
Built by a researcher who also teaches, with one mission: to make science communication better — physics shown as the real apparatus, with real numbers and the working on screen.
Nothing here is faked: planet positions come from real J2000 orbital elements solved through Kepler’s equation, periods are measured by integrating Newton’s law rather than looked up, and every number on screen is checked against the closed-form physics before it ships.
Each simulation is one HTML file — no install, no account, no ads, no tracking. It works offline on a locked-down school Chromebook and makes zero network requests after load.
