Many people have made great contributions to science. Some had bad ideas, or their theories were wrong, or maybe they weren't asking the right questions. Others had some facts true and others false. Many great scientific minds have made discoveries that went against the beliefs of most people, which angered people, but their discoveries have always had great influence in the scientific world and their ideas are still used in science today. But even some of the greatest scientific minds have made mistakes. I'm about to tell you about the contributions and achievements of Nicolaus Copernicus, who faced many of the same challenges as many great discoverers of 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 let's stick with Nicolaus Copernicus in this essay. He was born in Torun, Poland on February 19, 1473. Copernicus was born into a wealthy family. His father was a trader and his mother also came from a wealthy family. But after his father's death, he lived with his uncle Lukasz Watzenrode, a Catholic bishop. He went to university at a college called University of Krakow. where he studied Latin, mathematics, geography, philosophy and astronomy, but not the type of astronomy you might think, it was not really a science course in the modern sense. These included mathematics courses that taught students Aristotle's and Ptolemy's view of the universe, and also had to calculate the dates of holy days, as well as courses in navigating the stars at sea. In his course "Astronomy", they also taught...... middle of paper ...... a logic that Ptolemy's system lacked. But the problem with Copernicus' heliocentric model was that it showed that the planets moved in circular paths at the same speed. Conclusion: Nicolaus Copernicus certainly changed the world forever. It particularly changed the way of thinking not only of scientists, but also the way everyone thinks or perceives the world or the universe. It may have taken Copernicus a long time to publish his work, but people still knew him and his work in the end. It allowed the world to better understand the solar system. There were many great minds like Nicolaus Copernicus in his time who also made contributions to science, and many others who came after, perhaps even influenced by Copernicus's work. As Sir Isaac Newton said: “If I have seen further, it is by standing on the shoulders of giants ».”.
