Mathematical Tracts On Physical Astronomy, The Figure Of The Earth, Precession And Nutation, And The Calculus Of Variations is a book written by George Biddell Airy in 1826. The book is a collection of mathematical tracts that explore various topics related to physical astronomy, including the figure of the Earth, precession and nutation, and the calculus of variations. The first part of the book focuses on the figure of the Earth, including discussions on the shape of the Earth and the measurement of its dimensions. Airy also explores the effect of the Earth's rotation on its shape and the resulting gravitational forces. The second part of the book delves into precession and nutation, which are the changes in the orientation of the Earth's rotational axis over time. Airy discusses the causes of these changes and their impact on astronomical observations. Finally, the book concludes with a section on the calculus of variations, which is a mathematical field that deals with finding the optimal solution to a problem with multiple possible solutions. Airy applies this concept to celestial mechanics, exploring how it can be used to solve problems related to the motion of planets and other celestial bodies. Overall, Mathematical Tracts On Physical Astronomy, The Figure Of The Earth, Precession And Nutation, And The Calculus Of Variations is a comprehensive and detailed exploration of various mathematical concepts related to physical astronomy. It is a valuable resource for anyone interested in this field of study.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
