Nicolaus Copernicus

Nicolaus Copernicus was a man who brought change into the scientific world. He made a model of the solar system different from all the rest. Scientists before Copernicus like Ptolemy looked at the solar system as the Earth is in the center and all the other planets are revolving around it. This was called the geocentric theory. But during the Renaissance a new idea came to mind by Nicolaus Copernicus.

Copernicus was born in 1473 in Poland. When he was younger he did receive good education and took part in many subjects such as, science and math. While he was learning he also had many jobs outside of school.

He later created a manuscript explaining all about his new theory. He showed all of the people he knew. Copernicus’s theory states that the Earth is not at the center, the sun is the center of the solar system and all of the other planets revolve around it. This was called the heliocentric theory.

Nicolaus decided to get his manuscript published. Unfortunately, during the process of getting it published he suffered paralysis and internal bleeding. This happened in 1543 before his magnificent theory was published.

This is the difference between the two theories:

Ptolemy's Theory

Copernicus's Theory

Unfortunately, there was some controversy on Copernicus’s theory. Not many people believed in his idea. But a man named Galileo did believe in his new theory. Because Galileo was following in the footsteps of Nicolaus, he got put under house arrest. Sooner or later they did agree with Copernicus that his theory was correct.
