John Kepler was one of the most significant scientists of the scientific revolution of the Middle Ages. Kepler was a German-born astronomer and mathematician. It showed the entire orbit of the planet around the sun and not the sun orbiting the earth. Kepler formulated three laws, in which he defined the motion that governs the planets. He dedicated himself passionately to clubs. Kepler also became the founder of modern optics. His work in developing the Laws of Planetary Motion supersedes all discoveries in celestial mechanics. His successes demonstrated many things that modern scientists use today. Kepler revealed one of the most famous discoveries in astronomy. Planets orbit the sun in predictable patterns. The sun does not orbit the planets. Kepler posed the question of planetary motion. Later, Newton took the answer. Kepler also traced the paths of the planets transversely; their path was elliptical, not circular. The planets move in ellipses with the sun at one focus and prior to this in 1602, Kepler discovered, trying to understand the position of the Earth in its orbit, that as it sweeps an area defined by the Sun and the Earth's orbital path that the radius vector labels equal areas at equal times. This idea became very popular during the Scientific Revolution, as it stimulated much research. Kepler created the three laws of planetary motion. The primary law is that the planets designate elliptical orbits with the sun. This law was announced in 1605, after his major discovery about how the planet's orbit moves. The next law is: the line joining the planet closest to the sun extends in equal areas at equal times. In order for an object along an elliptical orbit to sweep the area with a uniform speed, the object moves q...... in the center of the paper ......, but also of modern optics. Kepler was the first to investigate image creation with a pinhole camera. He clarified the process of vision by refraction with the eye. Kepler was the first to design glasses designed for nearsightedness and farsightedness. He was also the first to explain how a telescope works and the principles of thought. John Kepler contributed to the scientific revolution so we can say that he made history. His findings may have changed the way we learn science. Kepler played a role in the historical improvement of astronomy and natural philosophy. He well defined planetary movement using three laws created by him. Thanks to him, modern optics was also simplified. Kepler wrote many informative books in which he thoroughly defines each of his topics. It includes details and explanations that scientists still refer to today.
