The Mathematics of Navigation is a comprehensive guide to the mathematical principles and techniques used in navigation, written by Edward Jones Willis and first published in 1921. The book covers a wide range of topics, including the geometry of the earth, the principles of spherical trigonometry, the use of logarithms and slide rules, and the calculation of latitude and longitude. It also includes detailed explanations of the use of navigational instruments such as the sextant and the chronometer, as well as practical advice on how to apply these techniques in real-world situations. The Mathematics of Navigation is a valuable resource for anyone interested in the history of navigation or the mathematics behind it, as well as for sailors, pilots, and other navigators who want to deepen their understanding of the subject.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
