INVENTOR FAMOUS PERSON👨🏻‍💻

 hello everyone🙌🏻 welcome back in my blog🤩

Today i want to share about inventor famous person 

The inventor famous person is JOHANNES KEPLER

okay, sure you guys are patient, let's see my blog😉

                         JOHANNES KEPLER

Johannes Kepler was born on December 27, 1571 in the city of Well der Stadt, which was then occupied by the Roman Empire, and is now Germany.

The German astronomer Johannes Kepler was a real giant in his field. Born in Weil der Stadt, he studied theology at the University of Tubingen, later transitioned to mathematics, and became a teacher in 1593. As part of his university assignments, Kepler created an annual calendar and almanac. It uses a sun-centered planetary system because it makes the calculations easier.

In 1596, Kepler published The Cosmic Mystery. With this work, Kepler became the first famous scientist to publicly support Copernicus. Johannes Kepler proposed that the sun pushes the planets in their respective orbits with a force that decreases according to the square of their distance. However, Kepler's calculations failed to predict the events in the sky satisfactorily. It needs more recent observations of the planets.

The great Danish astronomer Tycho Brahe (1546-1601) had a lot of planetary data, but had not yet prepared his observations for publication. In 1600, Kepler fled to Prague to escape religious persecution. He heard that Brahe had left Denmark and founded a new observatory outside Prague. So Kepler became Brahe's assistant; it was he who edited Brahe's data and prepared it for publication. As part of his task, Kepler is trying to determine the orbit of Mars. Brahe died the following year, but Kepler continued to work on the problem for six years. Success came when Kepler overcame his mistake - which most astronomers also make - that the planets move in a combination of circular motions.

Kepler analyzed the measurements Brahe had collected. His analysis of the data yielded several important findings. In 1609, Kepler summarized his findings in The New Astronomy. His book contains two of his three laws of planetary motion: (1) The planet follows a path, or orbit, which is elliptical. The sun is at one focus of its ellipse. (2) A line connecting a planet to the sun sweeps an equal area in equal time intervals. In other words, the planets do not move at a uniform speed, but rather move fastest when they are closest to the sun.

Kepler is also well known for the third law of astronomy. The third law, published in Harmony of the Worlds (1619), says: the power of three of a planet's distance from the sun divided by the square of its revolutionary period is a constant and the same for all the planets. This law means that the distance of a planet from the sun can be calculated if the period of its revolution is known.

Kepler published Brahe's data as Rudolphine Tables (1625). These tables have remained their best for several decades. It was Kepler's discoveries, which were taken from Brahe's data, which were the basis for Isaac Newton's law of universal gravity and at the end of his life Kepler died in 1630 in Regensburg, Bavaria.
