La Correspondance D'Henri Poincare: Mecanique Celeste

The letters in this volume cover Poincar 's multifaceted career in astronomy in its entirety, extending from the time of his first publications in 1880 to the end of his life in 1912. At a tender age, Poincar established his authority in questions of celestial mechanics, and his views were soon sought after on a vast array of questions by the leading astronomers and geodesists of his time, including C.V.L. Charlier, G.H. Darwin, H. Faye, F.R. Helmert, G. W. Hill, A. Lindstedt, A.M. Liapunov, N. Lockyer, S. Newcomb, K. Schwarzschild, and F. Tisserand. Poincar and his correspondents take up topics ranging from the three-body problem and perturbation theory to the determination of the geoide and the equilibrium figures of rotating fluid masses. The volume also sheds light on Poincar 's three terms as president of the Bureau of Longitudes, where he guided French astronomy and geodesy through ambitious projects, such as the measurement of an arc of meridian near Quito.

Les lettres du troisi me volume de la Correspondance de Poincar scandent toute son oeuvre astronomique, allant de ses premiers m moires sur les courbes d finies par une quation diff rentielle (1881), jusqu'aux analyses des hypoth ses cosmogoniques (1911). Encore tr s jeune, Poincar s'est fait remarquer pour sa ma trise des questions de la m canique c leste, de tel sorte que les astronomes et les g od siens l'ont souvent interpell , y compris O. Callandreau, C.V.L. Charlier, G.H. Darwin, F.R. Helmert, A. Lindstedt, A.M. Lyapunov, Simon Newcomb, Karl Schwarzschild et F. Tisserand.
