RPC History 4 L90

Hello! Here is my essay from Mr.Livingston: Summarize each of the inventions you studied this week and how they impacted history. Also, explain the most interesting thing you learned this week, and why.

The four inventors and inventions I learned about this week are: The Heliocentric Theory in lesson 86,
in Lesson 87 I learned about Nicolaus Copernicus,
in Lesson 88I learned about the great Andreas Vesalius,
and in Lesson 89 I probably learned about one of the greatest inventions of all time the pencil.

The Heliocentric Theory. In 1543, Nicolaus Copernicus detailed his radical theory of the Universe in which the Earth, along with the other planets, rotated around the Sun. … Galileo discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter.

Nicolaus Copernicus. Polish astronomer Copernicus is born. On February 19, 1473, Nicolaus Copernicus is born in Torun, a city in north-central Poland on the Vistula River. The father of modern astronomy, he was the first modern European scientist to propose that Earth and other planets revolve around the sun.

Andreas Vesalius. Andreas Vesalius (1514-1564) Andreas Vesalius was born on 31 December 1514 in Brussels, Belgium, then part of the Holy Roman Empire. He came from a family of physicians and both his father and grandfather had served the holy Roman emperor.

The Pencil. The modern pencil was invented in 1795 by Nicholas-Jacques Conte, a scientist serving in the army of Napoleon Bonaparte. The magic material that was so appropriate for the purpose was the form of pure carbon that we call graphite.

That’s it hope you enjoyed!
