Introduction
Have you ever heard of Nicolaus Copernicus, “The Father of Modern Astronomy”? Well Nicolaus Copernicus wasn’t just a Polish mathematician and astronomer, he took classes in medical and law. It was very hard for Copernicus to spread out his ideas because nobody believed him. Copernicus is very important today because of his accomplishments of the Heliocentric Theory.

“We ourselves are not sufficiently safeguarded to repel… an attack and we fear lest the enemy, who is already so near, should besiege us also… Therefore, we humbly appeal to Your Holy Majesty to… come to our aid as quickly as possible and to support us. For we are completely devoted to Your Majesty, even if we perish.
