In the frontispiece for Isaac Newton’s Method of Fluxions (1736), the ancient philosophers contemplate the principles of motion while the contemporary, seventeenth century gentlemen hunters utilize them in the quest for a moving target. The situation depicted is similar to modern day trap-shooting. The Latin inscription above the illustration reads, “The sensible measure of velocity.”
The title page for Newton’s The Method of Fluxions and Infinite Series; with its Applications to the Geometry of Curved-Lines. The work was completed in 1671, but Newton’s reluctance to publish resulted in it appearing posthumously in 1736 in a translation by John Colson (1680-1760), the fifth Lucasian Professor of Mathematics at Cambridge. (Newton was the second Lucasian Professor.) As Colson noted in the Preface:
I thought it highly injurious to the memory and reputation of the great author, as well as invidious to the glory of our own nation, that so curious and useful a piece should be any longer suppress'd.
A discussion of fluents and fluxions (in modern terms, a discussion of functions and their derivatives)
On pages 44 and 45 of his Method of Fluxions, Newton considered the determination of maximum and minimum points for a curve.
A discussion of finding the center of curvature of a given curve
