Johannes is said to have been a rather sickly child, but was impossibly brilliant and excelled through his schooling, despite constant bullying and teasing by the other pupils. Somewhat of a loner, Johannes considered himself as an outsider, and tended to keep to himself during his childhood years.
Kepler was introduced to mathematics and astrology at a young age, and began attending the University of Tbingen in 1587. There he concentrated solely on his studies, proving himself as a superb mathematician. He graduated from there in 1591 and went on pursuing various different studies, until April of 1594, when he was offered the position of teacher of mathematics and astronomy at the Protestant school in Graz, Austria - he immediately accepted.
In April 1597, Kepler married Barbara Mller, and together they had three children: Susanna (1602), Friedrich (1604-1611), and Ludwig (1607-1663). It was in that same year in which he married that he published his first significant piece of work, The Cosmographic Mystery, in which he explained his argument on the relative distances of the planets from the Sun in the Copernican System. It was in this work which he defended the Copernican theory that the Sun, rather than the Earth, was at the center of the solar system. ...Show more
