How it works

Every lab is a real simulation, checked against the formulas.

01 · PREDICTCommit to an answerGuess before you see. Wrong guesses are where learning starts.
02 · RUNWatch the physicsEvery number on screen comes from the simulation, not an animation.
03 · MASTERLevel up3–5 challenge levels per lab, from reading a graph to hitting a target.
