Newton & astrology

Are you sure that Newton spent much time on astrology? I read all 900 pages of Westfall (but admittedly 20 years ago) and I don't remember that. Of course, Newton spent lots of time on alchemy and theology, but that is a different story. --Paul Wormer 02:15, 28 November 2007 (CST)

Orbit

The Oxford dictionary states 1548 as the year of first appearance of "orbit" and mentions the track of the moon as one of its meanings. What is your answer to this, dr. Jensen? :-) --Paul Wormer 02:34, 28 November 2007 (CST)

I think I meant alchemy for Newton, not astrology. As for orbits, I relied on this major article: Bernard R. Goldstein, and Giora Hon, "Kepler's Move from Orbs to Orbits: Documenting a Revolutionary Scientific Concept. Perspectives on Science 2005 13(1): 74-111.
