Friedrich Johannes Kepler (of 1571-1630 ) He was a German philosopher, evangelical theologian, mathematician, astronomer, astrologer, and opticians.
Kepler discovered the planetary movements.
1594: Did he at the age of 23, a lecturer in mathematics at the
Protestant seminary in Graz. He also published at that time a paper on the "Kepler telescope. Already since 1590, he was in correspondence contact with Galileo Galilei.
1600: Ching Kepler to Prague and was the imperial court mathematician. During this time he began developing the first astronomical system. The published works of his later " Astronomia nova" contained the first and second law of Kepler (= laws of planetary motion).
1612: he moved to Linz. In the same year he lost his wife and his sons. In Linz Kepler taught as a mathematician, and married again. At the same time Kepler had also to his mother, who was accused of witchcraft to fight. With much effort and you got a legal opinion from the University of Tübingen He released his mother. Plagued by financial worries, Kepler was forced to flee with his family in Ulm.
1627: In Albrecht von Wallenstein, Kepler found a new supporter who asked him reliable horoscopes.
1630 : dies at the age of 58 years, Kepler in Leipzig.
summarized his works:
- "Astronomia nova": it describes Kepler, that the orbit of Mars around the Sun is not a circle but an ellipse (= first Kepler's law), and the farther a planet away from the sun is, the slower it moves (= second Kepler's law).
- "De Stella Nova": Kepler observed in 1604, the birth of a supernova. He challenged the prevailing view that the stellar vault is unchangeable.
- "Dioptrice" With this work, Kepler laid the groundwork for the appearance.
- "Stereometria": the so-called Kepler's Kepler Fassregel created the basis for calculating the volume of wine barrels.
- "Harmonices Mundi: This work contains the third" Kepler's Law "
- J. Kepler wrote other works, including an essay to the symmetry of snowflakes, various mathematical and technical activities, But above all, his "Rudolfinian Tables" (which later formed the basis for the theory of gravity) and other works with astrological and mystizistischem content
