[edit] question about Kepler's law

I thnik that your comment about the Kepler's law deserve to be included in the article, that is that these laws have been used by Newton to derive the law of gravitation. I would like to know and understand how Kepler, thanks to his observations, found his laws, and then which derivations Newton used. THanks --Nicop 19:23, 21 Oct 2004 (UTC)
