Mathematical Tracts On Physical Astronomy, The Figure Of The Earth, Precession And Nutation, And The Calculus Of Variations (1826)

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 and published in 1826. The book is a collection of mathematical tracts that explore various topics related to physical astronomy, the figure of the earth, precession and nutation, and the calculus of variations.The first tract in the book is dedicated to physical astronomy and discusses the motion of the planets, the theory of the moon's motion, and the calculation of eclipses. The second tract focuses on the figure of the earth and includes discussions on the shape of the earth, the measurement of its circumference, and the determination of its density.The third tract explores precession and nutation, which are the periodic changes in the orientation of the earth's rotational axis. Airy discusses the causes and effects of these phenomena and provides mathematical formulas for calculating them.The final tract in the book is dedicated to the calculus of variations, which is a branch of mathematics that deals with finding the optimal solution to a problem. Airy applies this concept to the problem of determining the shape of the earth's surface and provides a mathematical solution.Overall, Mathematical Tracts On Physical Astronomy, The Figure Of The Earth, Precession And Nutation, And The Calculus Of Variations is a comprehensive and insightful book that explores various mathematical concepts related to astronomy and the earth's physical properties. It is a valuable resource for anyone interested in the history of science and mathematics.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
