‎---- EDITON ORIGINALE ---- BEL EXEMPLAIRE ---- "By virtue of the spirit of his research J. Boussinesq can be considered one of the last figures of classical science in the nineteenth century... Although he approached mathematics only in order to apply it practically, he was led to some interesting analyses in seeking the solution of particular problems. In the field of elasticity he obtained some intuitive results when considering certain potentials (logarithmic potentials with three variables, spherical potentials with four variables). In 1880, Boussinesq came upon nonanalytic integrals of hydrodynamic equations. He also found some asymptotic solutions of differential equations corresponding to cases of physical indetermination...". (DSB II pp. 355/356) ---- Cajori pp. 462, 469 & 471**9046/M4‎
