Isaac Newton’s Principia Book 2
In the Principia, Book Two, Lemma II, Newton describes what is essentially the Product Rule for differentiation, applying it to calculate the `moments’ of quantities that are expressed as products of powers of other quantities whose moments are known.
One of the most readable of all the great classics of physical science, Opticks presents a comprehensive survey of 18th-century knowledge of light. Newton describes his experiments with spectroscopy, colors, lenses, reflection, refraction, and more, in language lay readers can easily follow.

The Newton Project Created in 1998, the Newton Project seeks to make facsimiles and transcriptions of Newton’s manuscripts available in electronic form and to display their original connections, along with full documentation relating to Newton’s reading such as written notes and annotations.
