How the big ideas of physics were really discovered: a guess, a test, a failure, a better model. Each title walks one concept through history, with a working simulation at every step and links to the original papers.
From Kanada's paramanu and Democritus's atomos to quarks and the Higgs boson. A clickable timeline of 31 models, discoveries and experiments, each with its own simulation: fire alpha particles at Thomson's atom, watch Rutherford's atom collapse, see why only some electron orbits fit.
Start the journey →The same journey format for other big ideas of physics. Each volume follows the evidence: what people believed, the experiment that broke it, and the model that replaced it.
