By Ronald S. Calinger, what a beautiful book, clearly written, conceptual in nature, placing Euler in the broader history of mathematics, the funding of science, and the Enlightenment, all in a mere 536 pp. of text. Here is one bit:
At midcentury Leonard Euler was at the peak of his career. Johann I (Jean I) Bernoulli had saluted him as “the incomparable L. Euler, the prince among mathematicians” in 1745, and Henri Poincaré’s later description of him as the “god of mathematics” attests to his supremacy in the mathematical sciences. Euler continued to center his research on making seminal contributions to differential and integral calculus and rational mechanics, and producing substantial advances in astronomy, hydrodynamics, and geometrical optics; the state projects of Frederick II required attention especially to hydraulics, cartography, lotteries, and turbines. At midcentury, when d’Alembert and Alexis Claude Clairaut in Paris, Euler in Berlin, Colin Maclaurin in Scotland, and Daniel Bernoulli in Basel dominated the physical sciences, Euler was their presiding genius.
Nor had I known that Rameau sent his treatise on the fundamental mathematics of music to Euler for comments.
Definitely recommended, you can order it here.
