His Major Contribution to Fluid Dynamics

Essai d’une Nouvelle Theorie de la Résistance des Fluides.

Two folding engraved plates. xlvi, 212 pp. 4to, cont. mottled calf (lower cover with a small abrasion), spine gilt, red morocco lettering piece on spine. Paris: David, 1752.

First edition of d’Alembert’s major contribution to fluid dynamics, in which “the differential hydrodynamic equations were first expressed in terms of a field and the hydrodynamic paradox was put forth…the essay was an important contribution. Hunter Rouse and Simon Ince have said that d’Alembert was the first ‘to introduce such concepts as the components of fluid velocity and acceleration, the differential requirements of continuity, and even the complex numbers essential to modern analysis of the same problem’.”–D.S.B., I, p. 115.

Nice copy. From the library of Marchese Giulio Stanga Carlo Trecco (d. 1832), amateur mathematician and physicist who formed a large collection of scientific instruments, with his shelfmark label at head of spine.
