He tested this intuition using two-dimensional plane figures - the triangle, square, pentagon, etc. In a flash of inspiration, he saw the orbits of all the planets around the Sun arranged so that regular geometric figures would fit neatly between them. He realised that the ratio of the two circles replicated the ratio of the orbits of Jupiter and Saturn. In preparation for a geometry class he had drawn a figure on the blackboard of an equilateral triangle within a circle with a second circle inscribed within it. On 19th July 1595 (NS), a sudden revelation changed the course of Kepler's life. When both predictions proved correct, he unexpectedly gained a reputation as a prophet. In his first almanac he predicted an exceptionally cold winter and a Turkish incursion into Austria. There were no clear distinctions between astronomy and astrology amongst his duties as 'mathematicus' Kepler was expected to issue an annual almanac of astrological predictions. Before taking his final examinations, however, he was recommended for the vacant post of teacher of mathematics and astronomy at the Protestant school at Graz in Austria, which he took up in April 1594, aged 23.

He intended to become a clergyman and when he graduated in 1591 he entered the TГјbingen faculty of theology. The idea of a Sun-centred universe had a mystical appeal. At that time Kepler was not particularly interested in astronomy. He also became an advocate of the controversial Copernican theory of the solar system, which he often defended in public debates. In 1587 Kepler went to TГјbingen University where he proved to be an excellent mathematician.

He turned to the world of ideas for escape and found solace in an abiding religious conviction. He considered himself physically repulsive (admitting to 'a dog-like horror of baths'), thoroughly unlikeable, an outsider. His know-all cleverness irritated his classmates, who frequently beat him up. His schooldays, though academically successful, were thoroughly miserable. With a view to recruiting the brightest minds for the Protestant clergy, a system of grants and scholarships was available to promising (male) children of poor families, and despite his ill health, Johannes was precociously brilliant. He spent a solitary, unhappy childhood, but at least he was fortunate in that the ruling Dukes of WГјrttemburg had created a relatively enlightened system of education in Swabia. His mother, an inn-keeper's daughter, had a reputation for witchcraft.Д«orn prematurely, Johannes was weak and sickly. His father was a bullying adventurer who earned a precarious living as a mercenary soldier and deserted the family when Johannes was 17. His grandfather had been mayor of the town but the Kepler family fortunes were in decline. Johannes Kepler was born on 6th January 1572 (NS) at Weil-der-Stadt in the German province of Swabia. Perceived not by the ear but by the intellect, are nothing but a continuous song for several voices, 27x27 (the square of the time) gives 729.
