RPC History Week 17 3-13-15

Today in this essay I will talk a little bit about one Greek philosopher, one Greek mathematician, and one Greek scientist. So first I will talk about a Greek philosopher, Thales.

Thales was the first philosopher of natural science and believed that everything came from water. Also Thales invented something called Thales’ Theorem. Thales’ Theorem is a famous mathematical principle that if A, B, and C are points in a circle, where the line AC is the diameter of the circle, then the angle ABC is a right angle.

Now I am going to talk about Archimedes a Greek mathematician. Archimedes is well-known as a brilliant mathematician who could solve almost every single problem. He invented the water screw, exponents, pulleys, levers, and several war machines.

Finally Hipparchus a Greek scientist cataloged and named 850 different stars using longitude and latitude to record their locations.
