||1671/72: 1671/72 Newton’s first publication appears as a letter in the Philosophical Transactions. It deals with his new theory of light, showing that a prism separates white light into its component colors. Huygens, Hooke and others objected so strongly that he vowed not to publish again. Fortunately that vow was not kept. *VFR The full text of that publication is here.  https://pballew.blogspot.com/2019/02/on-this-day-in-math-february-19.html
