Archimedes was born on 287 BC - 212 BC. His full name was Archimedes of Syracuse. He doesn’t have his full name shown; this is is because we haven’t found documents of his real full name. To everyone he is known as Archimedes of Syracuse. He was a Greek man. The things he was known for were mathematician, physicist, engineering, inventing, and astronomy. Archimedes also made several different types of things that were useful at that time period. He is considered to be the greatest mathematician of antiquity and one of the greatest of all time. He used the method of exhaustion to calculate the area under the arc of a parabola with the summation of an infinite series. He also gave a good estimate of pi.

An important reason why Archimedes is an important person is because of his discovery on the relationship between the surface and volume of a sphere and its circumscribing cylinder. He is known for his formulation of a hydrostatic, which is best known as Archimedes principle. Also he made a device for raising water which is still used in some developing countries. That is called the archimedes screw. Some other important utilities and tools he made were and still important today. For example, one thing was the lever. The lever was used to lift or pull objects. The lever is still used today. This an example of why Archimedes was an important man.

The biggest reason why Archimedes is still known today and is important is because of his math. Archimedes produced formulas to calculate the areas of regular shapes, using a revolutionary method of capturing new shapes by using shapes he already understood. For example, to estimate the area of a circle, he constructed a larger polygon outside the circle and a smaller one inside it. He first enclosed the circle in a triangle, then in a square, pentagon, hexagon, etc, each time approximating the area of the circle more closely. By this so-called “method of exhaustion” , he effectively homed in on a...
