Johannes KeplerThe Harmonies of the WorldBy the study of the orbit of Mars, we must either arrive at the secrets of astronomy or forever remain in ignorance of them. Johannes KeplerBiographyKepler, Johannes (1571-1630) who was a German astronomer and natural philosopher is noted for coming up with and verifying the three laws of planetary motion. These laws are now known as Kepler’s laws of Planetary Motion. Johanne was born on December 27, 1571.
ChildhoodJohanne was born in Weil der Stadt in Swabia and moved to nearby Leonberg with his parents in 1576. His father was a mercenary soldier and his mother was the daughter of an innkeeper. He was their first child. His father left home for the last time when Johannes was five, and is believed to have died in a war in the Netherlands. Whenever he was a child, Kepler lived with his mother in his grandfather’s inn.
Sources said that he used to help by serving in the inn. Customers were amused by the child’s unusual competence at math. Kepler’s early education was in a local school and then at a nearby seminary, from which, intending to be ordained, he went on to enroll at the University of Tbingen, a bastion of Lutheran orthodoxy. Johannes KeplerLeaving Prague for Linz Johannes years in Prague were peaceful, and scientifically productive. In fact, even when things went badly, he never seemed to have allowed external circumstances to prevent him from getting on with his work.
Things began to go very badly in late 1611. His seven year old son died. Kepler wrote to a friend that this death was particularly hard because the child reminded him so much of himself at that age. Then his wife died. Emperor Rudolf, whose health was failing, was forced to abdicate in favor of his brother Matthias, who, like Rudolf, was a Catholic but (unlike Rudolf) did not believe in tolerance of Protestants.
Kepler had to leave Prague. Before he departed he had his wife’s body moved into the son’s grave, and wrote a Latin epitaph for them. He and his remaining children moved to Linz (now in Austria). Marriage and Wine Barrels Johanne seemed to have married his first wife, Barbara, for love (though the marriage was arranged through a broker). The second marriage, in 1613, was a matter of practical necessity.
He needed someone to look after the children. Kepler’s new wife, Susanna, had a crash course in Kepler’s character. A dedicatory letter to the resultant book explains that at the wedding celebrations he noticed that the barrels of wine barrels were estimated by means of a rod slipped in diagonally through a hole, and he began to wonder how that could work. The result was a study of the volumes of solids of revolution (New Stereometry of wine barrels, Nova stereometria doliorum, Linz, 1615) in which Kepler, basing himself on the work of Archimedes, used a resolution into ‘indivisibles’.
This method was later developed by Bonaventura Cavalieri (c. 1598 – 1547) and is part of the ancestry of the infinitesima. Development of LawsHe was influenced by a mathematics professor, Michael Maestlin, an advocate of the heliocentric theory of planetary motion first developed by Nicolaus Copernicus. Kepler accepted the Copernican Theory immediately.
He believed that the simplicity of Copernican planetary ordering must have been God’s plan. In 1594, when Kepler left Tbingen for Graz, Austria, he worked out a complex geometric hypothesis to account for distances between the planetary orbits. Orbits that he mistakenly assumed were circular. (Kepler later found that planetary orbits are elliptic; nevertheless, these preliminary calculations agreed with observations to within 5 percent. ) Kepler then proposed that the sun emits a force that diminishes inversely with distance and forces the planets around in their orbits.
Kepler published his account in a treatise entitled Mysterium Cosmographicum (Cosmographic Mystery) in 1596. This work is significant because it presented the first comprehensive and cogent account of the geometrical advantages of Copernican theory. Kepler held the chair of astronomy and mathematics at the University of Graz from 1594 until 1600, when he became assistant to the Danish astronomer Tycho Brahe in the observatory near Prague. Kepler assumed his position as imperial mathematician
