German astronomer Johannes Kepler’s 448th birth anniversary today

Today is the 448th birth anniversary of German astronomer Johannes Kepler, who understood that the planets orbit the sun elliptically and most popular for his laws of planetary motion.

Johannes Kepler was born on December 27th in the German city of Weil der Stadt in what is at present Baden-Württemberg in 1571, to a mercenary father and a mother who was a healer and herbalist and was at one point pursued withchcraft.

Johannes Kepler was a German astronomer, mathematician, and astrologer. He is a key figure in the 17th-century scientific revolution, most popular for his laws of planetary motion, and his books Astronomia nova, Harmonices Mundi, and Epitome Astronomiae Copernicanae. These works likewise gave one of the establishments to Newton’s theory of universal gravitation.

Johannes Kepler was a mathematics teacher at a seminary school in Graz, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to the astronomer Tycho Brahe in Prague and the long run the supreme mathematician to Emperor Rudolf II and his two successors Matthias and Ferdinand II. He likewise showed mathematics in Linz and was a consultant to General Wallenstein.

Johannes Kepler had an early interest in cosmology, watching the Great Comet of 1577 and the lunar eclipse of 1580. After seminary, he studied philosophy at the University of Tübingen. He was an extraordinary mathematician and a skilled astrologer, providing individual students with regular horoscopes.

Furthermore, Johannes Kepler did principal work in the field of optics, designed an improved version of the refracting (or Keplerian) telescope, and was referenced in the telescopic disclosures of his contemporary Galileo Galilei. He was a relating individual from the Accademia dei Lincei in Rome.

Johannes Kepler lived in a period when there was no reasonable differentiation between astronomy and astrology, however, there was a strong division between astronomy (a branch of mathematics within the liberal arts) and physics (a branch of natural philosophy).

Johannes Kepler’s investigation into astronomy was likewise inspired by religious fervor: he believed that he was near finding God’s geometrical plan for the universe.

Johannes Kepler likewise joined religious arguments and reasoning into his work, motivated by the religious conviction and belief that God had made the world as per an intelligible plan that is open through the natural light of reason.

Johannes Kepler portrayed his new astronomy as “celestial physics”, as “an excursion into Aristotle’s Metaphysics”, and as “a supplement to Aristotle’s On the Heavens”, changing the ancient tradition of physical cosmology by regarding stargazing as a feature of a universal mathematical physics.

In 1604, while studying the orbit of Mars, Johannes Kepler understood that an elliptical orbit fit this information. He inferred that all planets move in ellipses, which is Kepler’s first law of planetary motion. His discoveries were printed in Astronomia Nova, which was published in 1609.

Johannes Kepler died on November 15 in 1630.
