EULER & COURNOT, Lettres de L. Euler à une Princesse d'Allemagne, 1842

Leonhard Euler (1707-1783) was one of the most prolific and influential mathematicians in history. His Letters to a German Princess are a collection of pedagogical correspondences that popularize topics in physics and philosophy for the Princess of Anhalt-Dessau. This 1842 edition is particularly notable for including a eulogy by Condorcet and annotations by Antoine-Augustin Cournot, a renowned French philosopher and mathematician. These annotations add a layer of analysis and context to the original text, making this work a valuable resource for the history of science and ideas.
