Newton's achievement was certainly built on that of others, Hooke included, but it was his mathematical formulation of the proofs that gave him primacy, and established the subsequent quantitative approach of all scientific proof.<br /><br />Feynman did indeed give up on the Principia, but being Feynman he went off and developed his own proof as documented in <a href="http://www.amazon.com/gp/product/0393039188/ref=as_li_ss_tl?ie=UTF8&tag=thpsfibl-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=0393039188" rel="nofollow">Feynman's Lost Lecture: The Motion of Planets Around the Sun</a>.timarrhttp://www.blogger.com/profile/06254802085744425067noreply@blogger.comtag:blogger.com,1999:blog-7366878066073177705.post-25889256965259680362012-01-26T21:05:53.948+00:002012-01-26T21:05:53.948+00:00Newton's second law is not easily implied from...Newton's second law is not easily implied from his Principia. I think you are thinking too highly of someone who used infinitesimals and then set them to zero. It took a lot of work to justify mathematically Newton's ideas, which were implanted in him by Hook mainly. Euler basically derived the second law. Newton's law of gravity was known for a while but nobody coudld prove it. Eevn Feynman admitted that he could not follow Newton's proof.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7366878066073177705.post-91310233251248819612009-12-03T22:47:29.705+00:002009-12-03T22:47:29.705+00:00good work!good work!Oscarhttp://www.gnarustyche.blogspot.comnoreply@blogger.com
