https://img.youtube.com/vi/IsAPxUpKdzs/0.jpg Three hours on how people worked out the rules of the physical world, from the first watchers of the sky to the instruments that now feel the ripples of colliding black holes.
It covers the hammer and the feather dropped on the Moon; the astronomers of Babylon and the Greek thinkers from Thales to Aristotle; Ibn al-Haytham's experiments with light and the compass of China; Copernicus, Kepler and Galileo; Newton's laws and universal gravitation; Torricelli's vacuum, Harrison's sea clocks and Rømer's measurement of the speed of light; steam engines, Carnot, Clausius, Boltzmann and the arrow of time; Galvani's frogs, Volta's pile, Faraday's lines of force and Maxwell's waves; Edison, Tesla and the current wars; the wave theory of light; X-rays, Becquerel, Marie Curie and radioactivity; the age of the Earth, from Kelvin to Rutherford; Einstein's year of miracles and general relativity; Planck, Bohr, Heisenberg and Schrödinger and the quantum; Feynman's sum over every path; Lise Meitner, Fermi and the splitting of the atom; Hiroshima and the nuclear age; Tsiolkovsky, Goddard, Gagarin and the Moon landings; Henrietta Leavitt, Hubble and Lemaître and the expanding universe; Schwarzschild, Chandrasekhar and Hawking and the black holes; the particles of the Standard Model and the Higgs boson; transistors, lasers and the clocks of GPS; the metre and the kilogram; Eunice Foote, Tyndall and Arrhenius and the warming air; and the questions still open, from dark matter and dark energy to a theory that joins gravity and the quantum.
