Johannes Kepler was born the son of a poor mercenary solider in 1571 in Weil der Stadt, Wurttemburg in the Holy Roman Empire. He began his education in Wurttemburg through a scholarship program designed to produce teachers and Lutheran pastors. In 1589, Kepler entered the theological seminary at the University of Tubingen. It was here that he first learned of Copernican astronomy from Michael Maestlin. The University of Tubingen awarded Kepler his MA in 1591. In 1594 Kepler interrupted his theological studies and accepted an appointment as a mathematics teacher at the Lutheran school in Graz, however, he was later dismissed from the position in 1600 due to religious persecution and a standing order for all Lutherans to leave the district. Earlier that year, Kepler temporarily worked with the Emperor Rudolf II's Imperial Mathematician, Tycho Brahe. . Kepler later traveled to Prague to join Brahe and work as his assistant until Brahe's death in 1601, whereby Kepler was appointed successor as The Imperial Mathematician. The appointment was the most prestigious honor in all of Europe for mathematics during his time.

While working as Brahe's assistant, Kepler was given the task of studying and attempting to understand the orbit for planet Mars. The orbit of Mars was particularly difficult because Copernicus had correctly placed the Sun at the center of the Solar System, but had erred in his assumption of circular planetary orbits. After numerous experiments and mathematical calculations, he finally realized the obits of the planets were in fact not circular as Aristotle had previously insisted and Copernicus assumed correct, but in fact were more elliptical in shape. The fact that Mars has the most elliptical of all orbits that Kepler had data on lead to Kepler eventually formulating the correct theory for the Solar System. After Brahe's death Kepler was able to obtain all of Brahe's data and observations. Utilizing the voluminous and precise data...

...On this day 442 years ago one of the greatest astronomically skilled mathematicians were born, his name was JohannesKepler. He was born around one o'clock in the afternoon. His parents were Katharina Kepler, and Heinrich Kepler. He grew up in a very poor family with his father being a soldier, and his mom an herbalist, or healer. He suffered from smallpox at the age of four and his father past away when he was five.

JohannesKepler was born on December 27, 1571 in Germany. He was a mathematician, astronomer, and astrologer. He was most famous for his eponymous laws of planetary motion. Based on his work on Astronomia nova, Harmonicies Mundi, and Epitome of Copernican Astronomy it provided a foundation for Issac Newton’s theory of universal gravitation.

...JohannesKepler was born December 27, 1571. He was a German mathematician, astronomer, astrologer, and a key figure in the seventeenth century. He is best known for his eponymous laws of planetary motion. He believed that God had created the world according to an intelligible plan that through the natural light of reason.
Kepler's first major astronomical work, Mysterium Cosmographicum, was the first published defense of the Copernican system. On July nineteenth...

...Context
JohannesKepler was born in the midst of an exciting and confusing time for Europe. The continent was entering the Renaissance, a reawakening of thought across the continent. By the time of Kepler's birth, the Renaissance had reinvigorated European culture, politics, philosophy, religion, literature, and science. The authority of the Catholic Church was challenged for the first time in centuries by the reformer Martin Luther, who pointed out the wrongs...

...Kepler: Scripture vs. Astronomy
JohannesKepler was one of the first natural philosophers that defended the design of the cosmos created by Nicolas Copernicus. Kepler argued that Copernicus’s system of the universe was not only the correct structure that man had been searching for, but also that by knowing this, he was able to more fully understand the thinking of his Creator. In this paper I will demonstrate how Kepler...

...In what ways did Tycho Brahe and Kepler break with the worldview of the Schoolmen?
Tycho Brahe had a very distinct need for accuracy. He did not believe that the Heavens were unchanging as established by Aristotle, but schoolmen did. Schoolmen believed in scholastics which was a form of Christian philisophy, which was vastly popular during Tycho's time of the 16th century. Part of the schoolmen's philosophy was that there was a realm outside of Earth called the Heavens. In...
