Celestial Encounters is for anyone who has ever wondered about the foundations of chaos In 1888 the 34yearold Henri Poincar submitted a paper that was to change the course of science but not before it underwent significant changes itself The ThreeBody Problem and the Equations of Dynamics won a prize sponsored by King Oscar II of Sweden and Norway and the journal Acta Mathematica but after accepting the prize Poincar found a serious mistake in his work While correcting it he discovered the phenomenon of chaosStarting with the story of Poincars work Florin Diacu and Philip Holmes trace the history of attempts to solve the problems of celestial mechanics first posed in Isaac Newtons Principia in 1686 In describing how mathematical rigor was brought to bear on one of our oldest fascinationsthe motions of the heavensthey introduce the people whose ideas led to the flourishing field now called nonlinear dynamicsIn presenting the modern theory of dynamical systems the models underlying much of modern science are described pictorially using the geometrical language invented by Poincar More generally the authors reflect on mathematical creativity and the roles that chance encounters politics and circumstance play in it.
