Feynman Says: “Newton implies Kepler, No Calculus Needed!”
|
Abstract: We recapitulate Feynman's demonstration that Kepler's laws follow from Newton's laws plus ordinary plane geometry: no calculus required. No differential equations, no conservation laws, no dynamics, no angular momentum, no constants of integration. This is Feynman at his best: reducing something seemingly big, complicated, and difficult to something small, simple, and easy. Issue: Volume 1 Pages: 57 - 72 |
