This marked the beginning of severe arguments between the two. In 1672 Hooke attempted to prove that the Earth moves in an ellipse round the Sun and six years later proposed that inverse square law of gravitation to explain planetary motions. Hooke wrote to Newton in 1679 asking for his opinion:- ... of compounding the celestiall motions of the planetts of a direct motion by the tangent (inertial motion) and an attractive motion towards the centrall body ... my supposition is that the Attraction always is in a duplicate proportion to the Distance from the Center Reciprocall ... =================================================================== Hooke claimed priority over the inverse square law and this led to a bitter dispute with Newton who, as a consequence, removed all references to Hooke from the Principia. =================================================================== Frequent bitter disputes with fellow scientists occurred throughout Hooke's life. On the other hand, we should note that he was on very good terms with some colleagues, particularly Boyle and Wren. Historians have described Hooke as a difficult and unreasonable man but in many ways this is a harsh judgement. There is no doubt that Hooke genuinely felt that others had stolen ideas which he had been first to put forward. " =================================================================== http://www-gap.dcs.st-and.ac.uk/~history/Mathematicians/Newton.html Newton The mechanics of the Copernican astronomy of Galileo attracted him and he also studied Kepler's Optics. >From his law of centrifugal force and Kepler's third law of planetary motion, Newton deduced the inverse-square law. After his 1679 correspondence with Hooke, Newton, by his own account, found a proof that Kepler's areal law was a consequence of centripetal forces, and he also showed that if the orbital curve is an ellipse under the action of central forces then the radial dependence of the force is inverse square with the distance from the centre. This discovery showed the physical significance of Kepler's second law. =================================================================== --- Kind regards, Aleksandr Timofeev http://www.friends-partners.org/~russeds/unknown/astrochem/oldeng.htm
