Many people have made their great contributions to science. Some had the wrong ideas, or their theories were wrong, or perhaps they weren't asking the right questions. Others had some facts right and some wrong. Many of the great minds in science made discoveries that went against the beliefs of many, which angered people, but their discoveries still had a great influence in the world of science and their ideas are still used in science today. But even some of the greatest minds in science have made mistakes. I am about to tell you about the contributions and successes of Nicolaus Copernicus, who faced many of the same challenges faced by many great discoverers in the past. I will also tell you about some of the mistakes made by Nicolaus Copernicus. Early life of Nicolaus Copernicus: Nicolaus Copernicus is the Latin name of the real name of this famous astronomer. His real name was Mikolaj Koppernigk, but in this essay we remain faithful to Nicolaus Copernicus. He was born in Torun, Poland on February 19, 1473. Copernicus was born into a wealthy family. His father was a merchant and his mother also came from a wealthy family. But after his father's death he lived with his uncle Lukasz Watzenrode who was a Catholic bishop. He went to college at a college called Krakow University. where he studied Latin, mathematics, geography, philosophy and astronomy, but not the kind of astronomy you might think, it was not really a scientific course in the modern sense. They were mathematics courses that taught students Aristotle and Ptolemy's view of the universe, and also had to calculate the dates of public holidays, and also courses in navigating among the stars at sea. In his “Astronomy” class, they also taught… halfway down the paper… logic that Ptolemy's system lacked. But the problem with Copernicus' heliocentric model was that it showed that the planets moved on circular paths at the same speed. Conclusion: Nicolaus Copernicus certainly changed the world forever. In particular, it has changed the way not only scientists think, but the way everyone thinks or sees the world or universe. It may have taken Copernicus a long time to publish his work, but in the end people still knew about him and his work. He had brought the world closer to understanding the solar system. There were many great minds like Nicolaus Copernicus in his time who would also make contributions to science, and many more who would come later, perhaps even influenced by Copernicus' work. Just as Sir Isaac Newton said: “If I have seen further, it is by standing on the shoulders of giants”.
