Notes to Isaac Newton 1. Of the many biographies of Newton, two
stand out: Westfall 1980 provides the most thorough intellectual
biography, and Hall 1992 is meticulous in not overreaching what
we truly know about him. Also helpful are Feingold 2004 and
Iliffe 2007. 2. This treatise was published in English
translations in 1736 and 1737, the latter under the title, “A
Treatise of the Method of Fluxions and Infinite Series, With its
Application to the Geometry of Curve Lines” (reprinted in [W, I,
27-137]; see also [M, III, 32-372] for a fully annotated version
of the Latin text with translation). 3. This specific statement
of the problem occurs in Hooke's last letter to Newton during
this exchange, a letter of 17 January 1680 that itself followed
an unanswered letter of 6 January. See [C, II, 313]. 4.
