His mother, Katharina, was accused of witchcraft inleading to a protracted and traumatic legal battle. Kepler fought tirelessly to defend her, and she was eventually acquitted in The ordeal, however, took a significant toll on Kepler and his family. Despite these hardships, Kepler continued his scientific work. He spent his later years in Linz and Ulm, producing a series of ephemerides and almanacs used for practical purposes like navigation and astrology.

These tables remained the most accurate astronomical data available for many years. Kepler's personal life also included two marriages. He married his second wife, Susanna Reuttinger, inwith whom he had six children, though only three survived to adulthood. Johannes Kepler died on November 15,in Regensburg, Germany, while on a journey to collect an outstanding debt.

He was buried in an unmarked grave, the exact location of which remains unknown due to the destruction caused by subsequent wars. Kepler's legacy is profound and enduring. His laws of planetary motion revolutionized our understanding of the solar system and provided a foundation for modern astronomy and physics. Kepler's work in optics paved the way for advancements in telescope design and the study of light.

He affirmed himself as an advocate of Copernicus and began defending his stance against other students. Although he desired to be a minister, Kepler was suggested by his superiors that he become a teacher of mathematics at Graz. It was here that he published his first major work, Mysterium Cosmographicum, in which he outlined the movement of the planets described by Platonic solids and defended the Copernican system.

It was the first work published to support Copernicus. His work gained significant ground in the academic community at the time, and Kepler sought to continue his work in astronomy. It was published in 3 volumes. Kepler also wrote a story about a trip to the Moon called The Dream, which was published after his death, in It could be called the first science fiction story.

Johannes Kepler died of fever on 15 November He was buried in Regensburg. There is a crater on the Moon named after Kepler. Previous post. Next post. The great discovery by Kepler In while he was trying to calculate the orbit of Mars Kepler realized it moved in an ellipse. Meanwhile, in Kepler calculated that Jesus was born in 4 BC.

In other words, even before discovering the johannes kepler biography referati law, Kepler had abandoned uniform circular motion as a physical principle.

Kepler contended that rotating massive bodies communicate their rotation to their satellites, so that the satellites are swept around the central body; thus the rotation of the Sun drives the revolutions of the planets and the rotation of the Earth drives the revolution of the Moon. In Kepler's era, no one had any evidence of Jupiter's rotation.

However, Kepler argued that the force by which a central body causes its satellites to revolve around it, weakens with distance; consequently, satellites that are farther from the central body revolve slower. Kepler noted that Jupiter's moons obeyed this pattern and he inferred that a similar force was responsible. However, this relation was approximate: the periods of Jupiter's moons were known within a few percent of their modern values, but the moons' semi-major axes were determined less accurately.

Kepler discussed Jupiter's moons in his Summary of Copernican Astronomy : [ 75 ] [ 76 ] 4 However, the credibility of this [argument] is proved by the comparison of the four [moons] of Jupiter and Jupiter with the six planets and the Sun.
