""A Treatise On The Analytical Dynamics Of Particles And Rigid Bodies: With An Introduction To The Problem Of Three Bodies"" is a comprehensive book written by E. T. Whittaker in 1917. The book provides an in-depth analysis of the principles of analytical dynamics, which is the study of the motion of particles and rigid bodies under the influence of forces. The book covers a wide range of topics, including the laws of motion, the principle of virtual work, Lagrange's equations, Hamilton's equations, and the theory of small vibrations.The book also includes an introduction to the problem of three bodies, which is a classic problem in celestial mechanics. This problem involves the study of the motion of three celestial bodies, such as planets or stars, under the influence of their mutual gravitational attraction. The problem of three bodies is notoriously difficult to solve and has been the subject of much research over the years.Whittaker's book is considered a classic in the field of analytical dynamics and has been widely used as a textbook in universities around the world. The book is written in a clear and concise style, making it accessible to both students and researchers in the field. It is an essential resource for anyone interested in the study of the motion of particles and rigid bodies, as well as the problem of three bodies in celestial mechanics.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
