Ofer Gal History and Philosophy of Science, University of Sydney How to make a mathematical law of nature: the (non-)discovery of the inverse square law of gravity Wednesday 18th October 14:05-14:55pm, Carslaw Building Room 373. The inverse square law of gravity (ISL) is the classic example for a mathematical law of nature, and much ink was shed debating whether it is Isaac Newton or Robert Hooke who deserves credit for its discovery. I will tell the real story of the establishment of the ISL, a story which involves no 'discoveries', have no place for priority disputes, runs in surprising routes, and shed very interesting light on what was new and exciting in the theory of universal gravity.
