Science of Mechanics 6 Revised edition

-From the Introduction by Karl Menger "Ernst Mach's book..., one of the great scientific achievements of the last century, remains a model for the presentation of the development of ideas in any field.... It is an inspiration to philosophers of science, a valuable source of information for historians of physics, and a splendid help to teachers of mechanics. Its first half is a most stimulating introduction of unsurpassed clarity and depth for beginners."
