The book has 584 pages (16 x 22.5 cm), with the original illustrations and tables.

The Principia is considered one of the most important works in the history of science. For many, it is the start of the Mathematics, Physics and Astronomy of the modern era. This is the most important book of Newton and is a must have for the libraries of any scientist even in the 21st century.

This book is a re-print of the 1st edition and it is the original work photographed as it was, with all the imperfections and difficulties a book of its age can present. Our aim is the preservation of these fine examples of creative human thinking in print.
