What goes up . . . Newton now online
An original manuscript containing Isaac Newton's famous laws of motion is among historic works of the great scientist being made publicly available online.
Cambridge University has published more than 4,000 pages of Mr Newton's most important works on a new digital library website.
They include the scientist's own annotated copy of 'Philosophiae Naturalis Principia Mathematica'.
First published in July 1687, 'Principia' not only contains the laws of motion but also Mr Newton's law of universal gravitation. It is widely regarded as one of the most significant works in the history of science.
Over the next few months the university library will upload thousands more pages, making almost the whole of its Newton collection available for anyone to view and download.
Work on the Cambridge Digital Library began in 2010, with the Newton collection being photographed last summer. Log on to http://cudl.lib.cam.ac.uk.
Digitisation of the Newton papers was made possible by a £1.5m (€1.75m) gift from the Polonsky Foundation, which supports education and the arts.
