Homework Quiz

What I learned about the life of Galileo is that he was born in the late 1500s and died around 1650.Galileo was critically acclaimed for inventing the telescope but in fact he was not the first to build it. Through the construction of his telescope he began to discover that the sun was actually the center of the solar system. When Galileo began to promote his theory he was tried for heresy under the Catholic Church because they still believed that the earth was the center of the solar system. With his life at risk Galileo had a choice, die or publicly announce that his theory was false he chose the safe way out.

Sir Isaac Newton known as one of the best scientists of all time was born in 1642 and died 1727.Newton was best known for his work with physics and calculus specifically motion, gravity, and light. Newton attended college at Trinity College Cambridge and received his Bachelor’s degree in 1665 and began teaching as a professor in 1669.Newton was a brilliant man but he was a very nervous man too, when it came to publishing his work he would never want to because he was afraid that he was going to be wrong, which caused him to have two mental breakdowns in his life. After the publication of his discoveries he was knighted in 1705.

Engines are an invention we use on a daily basis for transportation, electricity, and harvesting food. The first steam engine is said to be traced back to the first century A.D by a Greek man named Hero and he created a toy looking machine called an aeliopile that was powered by steam. Steam power did not become big until about 1,500 years later when the source of power was human and animal muscle and wind and water power it was then Denis Papin created the idea of steam moving a piston when suppressed in a cylinder. Then Savery and Newcomen used that invention and put it to good use by pumping water out of a mine shaft. With that came many more engines and eventually a advancement in the world like we see today.
