Johannes Kepler (27 December, 1571–15 November, 1630) was a prominent German astronomer, mathematician as well as a brilliant astrologer. Kepler had contributed to a great degree in the scientific revolution during the 17th century. He is very famous for the eponymous laws of planetary motion, which had been later codified by many astronomers. His exceptional work endowed a key foundation for Isaac Newton’s theory based on the universal gravitation. He also assisted Tycho Brahe who was a great astronomer. He even taught mathematics in Linz at Austria and played the role of an advisor for Genera Wallenstein. He had discovered the superior edition of refracting telescope that is known as the Keplerian Telescope. This great personality also talked about the telescopic inventions of Galileo.
Kepler had initiated the comprehensive research on the optics law. He also focused on Chronology, which was about dating all the essential events that took place in the lifetime of Jesus.
