Johannes Kepler
Michael Fowler, UVa Physics Link to Physics 109N Home Page and Other Topics! Link to Previous Lecture (Tycho Brahe) As a seven-month child, Kepler was sickly from birth, and contracted smallpox when very young. His vision was severely defective, and he had various other illnesses fairly constantly, some of which may have been hypochondria. He took twice as long as normal children to get through elementary latin. He did a little better when he got to the higher school at Maulbronn, a school which only half a century earlier was haunted by the ill-famed Dr. Faustus (ref 2). While lecturing to his math class in Graz, contemplating some geometric figure involving concentric circles and triangles on the blackboard, Kepler suddenly realized that figures of the type shown here determine a definite fixed ratio between the sizes of the two circles, provided the triangle has all sides equal, and a different ratio of sizes will occur for a square between the two circles, another for a regular pentagon, and so on. Mysterium Cosmographicum the mystery of the universe (explained). The crucial illustration from his book is shown below, the outer sphere being the orbit of Saturn, and the central part is shown magnified at top right.

Johannes Kepler is 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).

Johannes Kepler
The German astronomer Johannes Kepler, b. Dec. 27, 1571, d. Nov. 15, 1630, was the first strong supporter of the heliocentric theory of Copernicus and the discoverer of the three laws of planetary motion. He attended seminaries at Adelberg and Maulbronn before studying theology, philosophy, and mathematics at the University of Tubingen. At Tubingen, Kepler's scientific ability attracted the notice of the astronomer Michael Maestlin. Through Maestlin, Kepler became a supporter of the Copernican theory, although his teacher continued to expound officially the old Ptolemaic system. Kepler had planned to enter religious life, but he accepted a chair in mathematics and astronomy at Graz. At the age of 24, Kepler published Mysterium cosmographicum (Cosmographic Mystery, 1596), in which he defended the Copernican theory and described his ideas on the structure of the planetary system. Influenced by the Pythagoreans, Kepler viewed the universe as being governed by geometric relationships that conform to the inscribed and circumscribed circles of the five regular polygons. Although he was not a Copernican himself, Tycho Brahe, the mathematician at the court of Emperor Rudolph II at Prague, was so impressed with Kepler's work that in 1600 he invited Kepler to come to Prague as his assistant. Confronted with the Catholic persecution of the Protestant minority in Graz, Kepler gladly accepted. When Brahe died the following year, Kepler was appointed his successor and thus inherited Brahe's scientific legacy.

Johannes Kepler
27 Dec. 1571 in Weil der Stadt (near Leonberg) - 15 Nov. 1630 in Regensburg Johannes Kepler discovered that planets move round the Sun in elliptical orbits. He gave three mathematical laws of planetary motion. Kepler was a devout, but not completely orthodox, Lutheran. He was a convinced Platonist, which is to say that he looked for mathematical relationships in the observable universe. Kepler attended the University of Tübingen, where his mathematical ability was noticed by his astronomy teacher Michael Maestlin. Officially Maestlin taught geocentric (Ptolemaic) astronomy, but able pupils, among them Kepler, were also introduced to the heliocentric astronomy of Copernicus (published in 1543). Kepler originally intended to become a priest, but was persuaded to take up a post teaching mathematics at Graz. In 1596, Kepler published his Mysterium Cosmographicum, which argues for the truth of the Copernican system by giving a mathematical explanation of its structure (in terms of regular polyhedra). In 1600, Kepler went to Prague, as assistant to Tycho Brahe. Brahe died in 1601, but Kepler went on to use his observations to calculate planetary orbits of unprecedented accuracy.

Johannes Kepler (1571-1630) Johannes Kepler was born on December 27, 1571 in Weil der Stadt, Germany. Kepler's grandfather was supposedly from a noble background, and once Mayor of Weil. However, Kepler's father became a mercenary who narrowly avoided the gallows. Kepler's mother, Katherine, was raised by an aunt who was eventually burned as a witch. In later years, Katherine herself was accused of Devil worship, and barely escaped from being burned at the stake. Kepler had six brothers and sisters, three of which, died in infancy. In his youth, Johannes was described as: "...a sickly child, with thin limbs and a large, pasty face surrounded by dark curly hair. He was born with defective eyesight-myopia plus anocular polyopy (multiple vision). His stomach and gall bladder gave constant trouble; he suffered from boils, rashes, and possibly from piles, for he tells us that he could never sit still for any length of time..." (Koestler, p 24) From this inauspicious start, Johannes Kepler began his fascinating journey as a pioneer in astronomy.

Johannes Kepler wurde am 27. Dezember 1571 in der deutschen Kleinstadt Weil der Stadt in Württemberg geboren. Seine Mutter weckte Keplers Interesse für Astronomie: Sie zeigte ihm den Kometen von und die Mondfinsternis von . Trotz bescheidener familiärer Verhältnisse und einer kränklichen Natur konnte er ein Theologiestudium am Evangelischen Stift in Tübingen beginnen. An dieser Universität hörte er von den astronomischen Ideen des Nikolaus Kopernikus . Kepler wollte ursprünglich protestantischer Geistlicher werden, er nahm jedoch auf Grund seiner mathematischen Begabung im Jahre einen Lehrauftrag für Mathematik an der Universität Graz an.

Kepler interrupted his theological studies in 1594 to take up an appointment as mathematics teacher at the Lutheran school in Graz. He was dismissed from this position in September 1600, as all Lutherans were ordered out of the district. Earlier that year, Kepler had worked with Tycho Brahe Brahe died in 1601, and Kepler succeeded him as imperial

Johannes Kepler (1571-1630)
Johannes Kepler (1571-1630). Born on 27 December 1571 in Weil der Stadt, near Stuttgart, in a modest family. He graduated at age 20 from the University of Tuebingen, where he studied mathematics and astronomy under Michael Maestlin (1550-1631), an early supporter of the Copernican system. In 1594, while engaged in the final year of his studies in theology, he was given the chair of mathematics at Graz, where he became increasingly absorbed in astronomy. He was formally expelled from town in 1600 on account of his open adherence to the Protestant faith. He first came to Prague in 1599 to work as an assistant to Tycho Brahe , and upon Tycho's untimely death in 1601 inherited his massive stock of accurate planetary observations, as well as his job as Imperial Mathematician to Rudolf II. In 1612, following the downfall of Rudolf II he moved to Linz, in 1621 to Ulm, and in 1627 to Sagan. On the move again because of religious persecution, he fell ill, and died on 15 November 1630 in Regensburg. Through a quarter century of painstaking calculations Kepler brought the Copernican system to its modern form by replacing Copernicus circular heliocentric orbits by ellipses, with the Sun at one focus. The process through which he arrived at his justly famous Laws of Planetary Motion was often a contorted one, as Kepler's peculiar mixture of physical insight and mystical inclinations lead him to seek

A Short Biography to study for the Lutheran ministry . There he was introduced to the ideas of Copernicus and delighted in them. In 1596, while a mathematics teacher in Graz, he wrote the first outspoken defense of the Copernican system, the Mysterium Cosmographicum Kepler's family was Lutheran and he adhered to the Augsburg Confession a defining document for Lutheranism. However, he did not adhere to the Lutheran position on the real presence and refused to sign the Formula of Concord . Because of his refusal he was excluded from the sacrament in the Lutheran church. This and his refusal to convert to Catholicism left him alienated by both the Lutherans and the Catholics. Thus he had no refuge during the Thirty-Years War.
The Holy Roman Empire of German Nationality at the Time of Kepler Kepler was forced to leave his teaching post at Graz due to the counter Reformation because he was Lutheran and moved to Prague to work with the renowned Danish astronomer, Tycho Brahe. He inherited Tycho's post as Imperial Mathematician when Tycho died in 1601. Using the precise data that Tycho had collected, Kepler discovered that the orbit of Mars was an ellipse. In 1609 he published
