Kepler is an AI scientist that doesn't guess. You film a physics experiment with your phone; Kepler tracks the object, writes candidate laws of physics as code, fits each law on the start of the film and judges it on the part it never saw, then bets on what happens next. The prediction is sealed (sha256) before reality checks it. Filmed at home: Kepler predicted 7.6 s of a pendulum's motion 3.5 mm off on average, rejected free fall for a falling paper bowl and found air drag, and called a ball's landing spot (39.8 cm) seven minutes before the throw - it landed in the basket. No number comes from a language model: every number is computed and checkable.
