Powder Puff Principles

This seven volume set, published for the first time in paperback, is intended to give in as complete a form as possible the correspondence of Isaac Newton. The project to bring Newton's correspondence to the public domain began in 1947 when the Newton Letters Committee was founded at the Royal Society, with the following principles being adopted for the work: to include all letters written by Newton; all letters addressed to Newton (both to be published in extenso); extracts from contemporary letters referring to Newton; and shorter memorabilia illustrating the life of Newton, particularly minor and hitherto unpublished manuscripts of Newton. To supplement the correspondence, there are notes throughout the series which provide connecting links relating to any given letter, as well as those of a biographical and bibliographical nature. There are also elucidatory notes that contain explanations of language, symbols and obscurities. Mathematical formulæ are also explored, showing a richne

Newton's Principia is perhaps the second most famous work of mathematics, after Euclid's Elements. Originally published in 1687, it gave the first systematic account of the fundamental concepts of dynamics, as well as three beautiful derivations of Newton's law of gravitation from Kepler's laws of planetary motion. As a book of great insight and ingenuity, it has raised our understanding of the power of mathematics more than any other work. This heavily annotated translation of the third and final edition (1726) of the Principia will enable any reader with a good understanding of elementary mathematics to easily grasp the meaning of the text, either from the translation itself or from the notes, and to appreciate some of its significance. All forward references are given to illuminate the structure and unity of the whole, and to clarify the parts. The mathematical prerequisites for understanding Newton's arguments are given in a brief appendix.
