Imagine that you are Nicolaus Copernicus. Write a short autobiographical statement that talks about who you are, where you’re from, and some of your important contributions.

My name is Nicolaus Copernicus and I am a mathematician and astronomer. I helped formulate a model of the universe that claimed that the Sun, not the earth was at the center of the universe.

I was born in Royal Prussia which was a part of Polish territory. I could speak quite a number of languages such as German, Latin, Polish, Greek, Italian, a little bit of Hebrew, and had good knowledge on a number of topics.

I helped derive a quantity theory of money and also formulated an important economic principle which was known as Gresham's law.

the great wall of china worked as a defense for the feudal states of the zhou dynasty to the north. during the warring states period more walls were put up to defend the borders of the different kingdoms. it was semi successful because despite the wall, the mongols eventually conquered china also the great wall provided protection to the economic development and cultural progress, safeguarded the trading routes such as the silk road, and secured transmission of information and transportation. @jayxboof
