Johannes Kepler

Life and Works Johannes Kepler was born on December 27, 1571 in Weil der Stadt, a little town near Stuttgart in Württenberg 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. Before concluding his theology studies at Tübingen, in March/April 1594 Kepler accepted an offer to teach mathematics as the successor to Georg Stadius at the Protestant school in Graz (in Styria, Austria).

On August 3, 1611 Kepler's wife, Barbara Müller, died. In pursuit of an accurate printer for the Tabulae Rudolphinae, he moved to Ulm near the end of 1626 and remained there until the end of 1627. 2. 3. Kepler biography.

Kepler biography

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). A large quantity of Kepler's correspondence survives. Childhood. Johannes Kepler. Johannes Kepler (1571-1630) Johannes Kepler was born in Weil der Stadt in Swabia, in southwest Germany.

Johannes Kepler

His paternal grandfather, Sebald Kepler, was a respected craftsman who served as mayor of the city; his maternal grandfather, Melchior Guldenmann, was an innkeeper and mayor of the nearby village of Eltingen. His father, Heinrich Kepler, was "an immoral, rough and quarrelsome soldier," according to Kepler, and he described his mother in similar unflattering terms. From 1574 to 1576 Johannes lived with his grandparents; in 1576 his parents moved to nearby Leonberg, where Johannes entered the Latin school.

In 1584 he entered the Protestant seminary at Adelberg, and in 1589 he began his university education at the Protestant university of Tübingen. KEPLER, Johannes. Johannes Kepler.

Kepler is best known for his theories explaining the motion of planets. Kepler was born on December 27, 1571, in Weil der Stadt, Germany. As a university student, he studied the Polish astronomer Nicolaus Copernicus' theories of planetary ordering. Copernicus (1473-1543) believed that the sun, not the earth, was the center of the solar system, a theory that contradicted the prevailing view of the era that the sun revolved around the earth. In 1600, Kepler went to Prague to work for Danish astronomer Tycho Brahe, the imperial mathematician to Rudolf II, emperor of the Holy Roman Empire. Kepler's research was slow to gain widespread traction during his lifetime, but it later served as a key influence on the English mathematician Sir Isaac Newton (1643-1727) and his law of gravitational force.

Johannes Kepler, (born December 27, 1571, Weil der Stadt, Württemberg [Germany]—died November 15, 1630, Regensburg), German astronomer who discovered three major laws of planetary motion, conventionally designated as follows: (1) the planets move in elliptical orbits with the Sun at one focus; (2) the time necessary to traverse any arc of a planetary orbit is proportional to the area of the sector between the central body and that arc (the “area law”); and (3) there is an exact relationship between the squares of the planets’ periodic times and the cubes of the radii of their orbits (the “harmonic law”).

Qui ne le sait aujourd'hui ? Mais combien celui qui les découvrit est méconnu ! Il ne faut pas accuser trop vite l'ingratitude de l'histoire. Kepler écrivit la pièce maîtresse de son œuvre comme aucun créateur ne le fit jamais : il confia au livre imprimé les méandres de ses démarches. Il fut presque illisible. Sans doute, l'homme qui eut ce rôle décisif et qui marqua de son empreinte d'autres domaines de la physique fut-il reconnu par les plus grands promoteurs de la science rationnelle nouvelle, et c'est à lui que Descartes rapporte en particulier l'inspiration de sa Dioptrique.

Johannes Kepler

Savant génial et obstiné, il est l'un des fondateurs de l'astronomie moderne. Sa découverte, purement empirique, des lois du mouvement des planètes a bouleversé la pensée de son époque et ouvert la voie à Newton. Une enfance dure, mais une intelligence précoce.
