Originally published in 1904, as part of the Cambridge Physical Series, this book was written to provide an accessible introduction to the principles of mechanics. The text analyses the principles as they developed in chronological order and places them in their historical context, with discussion of pioneering figures. Examples are included, but only where necessary and not in such abundance that they would confuse the reader. Illustrative figures are also incorporated throughout. This book will be of value to anyone with an interest in mechanics, physics and the history of science.
