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 featuring all the amendments Newton made to his own texts or a more readable (normalised) version. We also make available translations of his most important Latin religious 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 scientific and mathematical writings, Newton also wrote many alchemical and religious texts.
We have published over four million words of text since January 2008, and have created a special section for reviewers working for the UK Research Excellence Framework (REF). This provides a list of every document published during the current REF cycle, along with key Research Inputs, Translations of major Latin texts and podcasted interviews with historians. Reviewers should refer to the main site in order to understand the way in which the documents have been classified and arranged within the site as a whole.
