Letters of Euler, on Different Subjects in Natural Philosophy Addressed to a German Princess, With Notes, and a Life of Euler, Vol. 2 of 2 is the latter half of a series publishing the letters of mathematician Leonhard Euler. The intended recipient of these letters was Friederike Charlotte of Brandenburg-Schwedt and her younger sister Louise, all of which were written between 1760 and 1762. The letters were initially published as a result of the insistence of Catherine II who believed that they were treasures the general public deserved access to. Since Euler was a mathematician, first and foremost, the letters often begin with basic explanations of size and mathematics. As the letters progress, however, Euler introduces other subjects of import such as science, politics, history, physics and philosophy. Ever the gentleman, he consistently attempts to infuse his letters with engaging information and personal touches that allow the recipient (and by proxy the reader) a sense of his own feelings on the logical concepts and intricate social and political topics he typically discusses. His passion for these topics flows through the text and makes these subjects interesting even to readers who might be put off by the suggested topics. Truly a master of discourse, Euler proves on every page that his ability to captivate any audience (even a royal one) does not diminish with time. Letters of Euler, on Different Subjects in Natural Philosophy Addressed to a German Princess, With Notes, and a Life of Euler, Vol. 2 of 2 is the second half of an exciting compilation of letters written by Leonhard Euler. These letters provide a unique glimpse into historic Switzerland and Germany as Euler provides information about both countries in his correspondences.
