 But, in the midst of all these vicissitudes, the length of the major axes and the mean motions of the planets remain permanently independent of secular changes. They are so connected by Kepler's law, of the squares of the periodic times being proportional...  Mechanism of the Heavens - Page xivby Mary Somerville - 1831 - 621 pagesFull view - About this book
