Ask what happens when you change a physical system. Fieldglass turns that question into an executable investigation: define the measurement, fit competing models, save forecasts before retrieving the new observations, measure the outcome, and revise the fit. Using nine real pendulum recordings, it predicted a complete swing at a shorter length. The square-root forecast was 0.999 seconds; three separate sensor recordings measured 1.023 seconds. The measurement fell inside that model’s original tolerance; it fell outside the two alternatives’ ranges. Judges can reveal the historical outcome, verify the calculations, change the length, and compare original and revised models in a credential-free browser experience. A separately authored yacht investigation ran on the same frozen executor and keeps its less successful result visible. Our ambition is to make physical investigation something a person can ask for, inspect, and reuse.
