Identifier: Coll-33/Quarto A [25]
Scope and Contents
David Gregory's solution to Sir Edmund Halley's problem, proposed during Gregory's composition of the "Tract on Fluxions", of finding the rotary motion in a sphere struck by another sphere. (Halley's solution is in Coll-33/Quarto A [7].) It is built on some basic lemmas and includes a reference (possibly after the date given) to proposition 40 of the "Tract on Fluxions".
