This review is from: Feynman's Lost Lecture: The Motions of Planets Around the Sun: Motion of Planets Around the Sun (Paperback)
Ingenious and imaginative proof of the Kepler's law of elipses, as first described by Isaac Newton, explained in terms of high school geometry by Richard Feynman. Readable and understandable whilst lightly challenging.
