  1. Step1🌞CopernicusEuropean HistoryHe dared publish On the Revolutions only on his deathbed: the Sun to the center, Earth made a planet — the revolution began with a swap of seats.See this figure →
  2. Step2🪐KeplerEuropean HistoryHe showed the planets travel ellipses, not "perfect circles" — for the first time, the truth of the heavens bowed to data rather than to aesthetics.See this figure →
  3. Step3🔭GalileoEuropean HistoryA telescope aimed at Jupiter revealed four moons orbiting it — "everything circles Earth" went bankrupt on the spot. It also brought him to his knees before the Inquisition.See this figure →
  4. Step4🔍DescartesPhilosophyPhilosophy took the baton: rebuilding the foundations of all knowledge from "I think, therefore I am" — the new science needed a new account of what counts as knowing.See this figure →
  5. Step5🍎NewtonEuropean HistoryThe Principia closed the arc: the same law drops the apple and holds the Moon in orbit — heaven and earth, under one mathematics at last.See this figure →
