"On March 13, 1964, Feynman delivered a lecture to the Caltech freshman class, \"The Motion of Planets Around the Sun\"why the planets move elliptically instead of in perfect circles. For reasons unknown, most probably for his own amusement, he chose to make the argument using mathematics no more advanced than high-school plane geometry. Isaac Newton had pulled off much the same trick nearly 300 years earlier in his masterpiece, the Principia. Feynman, unable to follow Newton's obscure proof, invented his own original, geometrical proof in the Caltech lecture." . . . . . . . . . .
