During the Middle Ages, there was a golden era for science and technology where the scientific revolution took place. The scientific knowledge began to grow by leaps and bounds. Scientists did many experiments and they concluded through their observations. Among the greatest scientists, Copernicus, Kepler and Galileo involved in a major role.
Firstly, Nicolas Copernicus, who was a Polish scientist, studied and checked status about motion of heavenly objects. He mentioned after analyzing the observation that we should be in a heliocentric solar system.He also rejected the geocentric theory which the catholic church believed. Heliocentric theory means all the other planets rotate around the sun instead of the earth. Copernicus didn't have clear evidence to prove his claims. Afterwards, he kept it with his until he gets a mathematical and physical proof.
Secondly, Johanna Kepler who was a German mathematician, astronomer and astrologer, studied about most significant applications of physics laws which were related to astronomy. He was able to prove that planets rotate in a elliptical orbits. However, he failed to conclude about the structure about the solar system. He was given many honors for his contribution to the science and technology. Some of the honors are Kepler's law of planetary motion, Kepler asteroid, Kepler's star, and Kepler's crater on the moon.
Thirdly,Galileo Galilee was an Italian scientist. He was a physicist, mathematician, astronomer and a philosopher. Moreover, he is called as father of modern observational astronomy, father of modern physics, father of science and father of modern science. He illustrated that gravity accelerated all objects towards the earth at the same rate. Furthermore, he accepted Copernicus on heliocentric theory. Galileo published Dialogue on the Two Chief Systems in the World which conveys more on heliocentric theory of the universe. He proved his claims with evidence taken from the study of physics.In addiction, he invented the telescope in order to look at the sky.
To sum up, many scientists contributed to this world in numerous ways. Among those characters, Copernicus, Kepler and Galileo play a vital role.They have done their responsibility as scientists.
