Copernicus, Kepler and Galileo challenge Church ideas about earth's place in the heavens. These two colorful characters made crucial contributions to our understanding of the universe: Tycho's observations were accurate enough for Kepler to discover. Johannes Kepler (). Johannes Kepler was born in Weil der Stadt in Swabia, in southwest Germany. His paternal grandfather, Sebald Kepler, was a.

Men like Copernicus, Kepler, Galileo, and Descartes had all helped develop a new view of nature. When Newton went to Cambridge, everyone was still studying the old nature.
- Tycho Brahe and Johannes Kepler
Isaac Newton was born on Christmas Day,the same year Galileo died. He did much of his greatest work during a two year period from to when he was at the village of Woolsworth to escape the Great Plague which was ravishing London. His life was troubled by angry conflicts and bitter feuds with colleagues and friends. Twice these feuds led to breakdowns; other times they led to bursts of brilliant new achievements.
He died inat the age of Years later it was discovered that much of his erratic behavior may have been caused by mercury poisoning. Recent samples of his hair showed he had forty times the level of mercury considered normal. Newton discovered the origin of color. He discovered the nature of gravity. He invented the first reflecting telescope. He wrote and published the book Mathematica Principia, which provided a detailed explanation of the laws of gravity and motion, particularly as they applied to astronomy.
Tycho Brahe and Johannes Kepler
He was knighted as Sir Isaac Newton and became president of the Royal Society, a post he held until his death. He was one of the most creative geniuses the world has ever seen and to many people the greatest scientist who ever lived. While Galileo's discoveries brought humankind to the brink of a new age, Newton took it the rest of the way. Kepler discovered that Mars was moving about the sun not in a perfect circle but in an ellipse — contradicting Plato's belief about perfection and the heavens.
Kepler proposed that laws about materiality that applied to things on earth applied also to the heavens. Around the yearin Holland, the telescope was invented — a tube with a convex lens at one end and a concave lens on the other.
The invention has been described as a collaboration between two makers of spectacles and a third person who was a mathematician. A 35 year-old scientist named Galilei Galileo, from Pisa Italy, heard about the invention, and in he made his own telescope, with a magnifying power of eight. The telescope as the writer Steven Johnson points out was part of a chain of developments connected to printing, the rise of literacy and lens-making for eye glasses.
And now lenses would contribute to science regarding what was viewed as the heavens and eventually to science regarding the microscopic.
The Galileo Project | Science | Johannes Kepler
Galileo was a Catholic and a progressive thinker. Aristotle's views, previously considered radical in Europe, had become the conservative point of view, and, like Francis Bacon, Galileo was opposed to Aristotelian ideology.
Galileo was interested in the mechanics of motion, and he was at odds with Aristotelian professors talking of things sinking or floating according to their will or essential natures and of things falling because they wanted to return home, as if the inanimate contained spirit and will. Galileo had grasped the idea of force as mechanical. He drew revolutionary conclusions that in the 20th century would seem common sense: His views annoyed theologians, but his ideas interested those wanting to measure the flight of cannon balls.
Inwith his telescope, Galileo discovered the moons of Jupiter, and soon afterward he found spots on the sun and the hills and valleys on the surface of the moon.
Copernicus, Kepler and Galileo
This ability to see where others could not got him into trouble with the Church, whose authorities put ideology ahead of scientific, or empirical discovery.
Their theology was deemed correct, and it was for Galileo to conform to it, not for the Church to adopt the science of Galileo or anyone else's science.
Galileo had demonstrable evidence that Copernicus had been correct. And among some of the Aristotelians of the old scholastic school of thought — who forgot Aristotle's admonition to investigate — came condemnation of the telescope.
InGalileo visited Rome and exhibited the wonders of the telescope to the pontifical court. He tried to produce scriptural confirmation of the view that the earth went around the sun.
The Church warned him that he should limit himself to study of the physical world and to avoid applying his ideas to theology. In the Church condemned as absurd and heretical the view that the earth moved around the sun, and the Church made expressions of this view forbidden reading. Pope Paul V instructed Galileo to refrain from teaching the doctrine, and Galileo promised to obey.
The Church, meanwhile, had been burning a few at the stake for their heresies. Giordano Bruno had been burned to death in Rome for his Pantheism. Another Pantheist, Lucilio Vanini, was condemned as an atheist and burned at the stake in in Toulouse, in southern France.Copérnico, Galileo, Kepler y Newton
