AI Summary

A new book by Caltech historians Jed Buchwald and Mordechai Feingold examines Isaac Newton’s life during the twenty years before he published *Principia Mathematica* in 1687. The authors used newly digitized scans of Newton’s early writings to build a portrait of the young scholar. Their research shows Newton as a curious, social figure whose interests shifted frequently, contrasting with the usual image of a solitary, egotistical genius. The book focuses on the period when Newton was 44 and highlights how his varied pursuits shaped his later work.
