This lively collection of lectures presented at the symposium by prominent scholars was collected and edited by Marcia Stayer with the assistance of Boris Castel. The chapters outline the influence of the Principia on the work of Newton's contemporaries - such as Adam Smith - and on many areas of present-day science: particle physics, optics, astronomy, and non-mechanical fields such as computer theory. Contributors include A.P. French, Werner Israel, W.H. Newton-Smith, David Raphael, Stephen Smale, Steven Weinberg, Richard S. Westfall, and Denys Wilkinson. This book will be of interest to both general readers and students of science.
