Welcome to the Newton Project
The Newton Project is a non-profit organization dedicated to publishing in full an online edition of all of Sir Isaac Newton’s (1642–1727) writings — whether they were printed or not. The edition presents a full (diplomatic) rendition of all the amendments Newton made to his own texts, but also offers more readable (normalized) version. We will also make available translations of his most important religious and scientific texts.
Although Newton is best known for his theory of universal gravitation and discovery of calculus, his interests were much broader than is usually appreciated. In addition to his celebrated natural philosophical writings and mathematical works, Newton also wrote many religious texts and alchemical tracts.
Over 5.2 million words are currently online and more are on the way.
