A selection of Sir Isaac Newton’s Papers have been made available online by Cambridge University Library. The initial selection which is now available concentrates on his mathematical work in the 1660’s and includes his Waste Book where he developed much of his work on calculus. There is also Newton’s annotated copy of Philosophiae Naturalis Principia Mathematica, laying out his laws of motion and gravity.
You can access this fantastic resource here. More manuscripts will be added over the next few months.
Newton’s Trinity College Notebook is featured in BBC Radio 4’s ‘In Our Time’ discussing how the invention of writing made the scientific revolution of the Enlightenment possible, which you can listen to here.
