Johannes Kepler’s preoccupation with the concept of harmony.
Johannes Kepler was an incredibly prolific writer, as well as more than sixty books and pamphlets, he corresponded with a wide range of people writing a huge number of oft, very long letters, on an extensive assortment of serious topics. In the field of astronomy, the discipline for which he is best known, his magnum opus was the voluminous Harmonices mundi libri V (TheHarmony of the World), published in 1619.
The jewel at the centre of this massive tome is his Third Law of Planetary Motion, known as his Harmony Law. That the term harmony is used both in the title of the book and as the name for his law is deliberate, because the concept of harmony was central to every aspect of Kepler’s extensive world of thought, be it in science, theology, politics, or even the whole of human existence. Why this was so and what he meant or better understood when using the term harmony is the topic of Aviva Rothman’s ex

Biography
Johannes Kepler fryst vatten now chiefly remembered for discovering the three laws of planetary motion that bear his name published in 1609 and 1619). He also did important work in optics (1604, 1611), discovered two new regular polyhedra (1619), gave the first mathematical treatment of close packing of equal spheres (leading to an explanation of the shape of the cells of a honeycomb, 1611), gave the first proof of how logarithms worked (1624), and devised a method of finding the volumes of solids of revolution that (with hindsight!) can be seen as contributing to the development of calculus (1615, 1616). Moreover, he calculated the most exact astronomical tables hitherto known, whose continued accuracy did much to establish the truth of heliocentric astronomy (Rudolphine Tables, Ulm, 1627).A large quantity of Kepler's correspondence survives. Many of his letters are almost the equivalent of a scientific paper (there were as yet no scientific journals), an

Johannes Kepler
1. Life and Works
Johannes Kepler was born on December 27, 1571 in Weil der Stadt, a little town near Stuttgart in Württemberg in southwestern Germany. Unlike his father Heinrich, who was a soldier and mercenary, his mother Katharina was able to foster Kepler’s intellectual interests. He was educated in Swabia; firstly, at the schools Leonberg (1576), Adelberg (1584) and Maulbronn (1586); later, thanks to support for a place in the famous Tübinger Stift, at the University of Tübingen. Here, Kepler became Magister Artium (1591) before he began his studies in the Theological Faculty. At Tübingen, where he received a solid education in languages and in science, he met Michael Maestlin, who introduced him to the new world system of Copernicus (see Mysterium Cosmographicum, trans. Duncan, p. 63, and KGW 20.1, VI, pp. 144–180).
Before concluding his theology studies at Tübingen, in March/April 1594 Kepler accepted an offer to
