Archimedes also invented weapons, including a device which used mirrors to focus the Sun’s rays at enemy ships, setting fire to them. In modern times, it has also been used as a method of generating electricity when connected to a generator. He famously stated “Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.” He is famous for the invention of the Archimedes screw, a simple machine that can be used to move water efficiently. The earliest mathematical descriptions of a lever are from Archimedes. He also produced a large amount of work in the field of mechanics. This principle explains how ships and boats float on water. The principle states that the upward force of buoyancy is equal to the weight of the liquid that is displaced by the object. The Archimedes principle is important as it can describe buoyancy. As well as this work he also produced other ideas in the field of hydrostatics. He could use this idea to measure the volume of the crown to calculate the crown’s density and compare this to the known density of gold. This made him realized that the increase in the volume of the water in the bath is equal to the volume of the object submerged. While taking a bath, he notice that the water rose when he got in. Archimedes struggled to devise a way to measure the volume of the crown, which he needed to calculate the density. There were suspicions that the goldsmith had mixed the gold with other metals in an attempt to save money. The king allegedly asked to investigate whether one of his crowns was pure gold or not. At his request there was a sculpture of a cylinder and a sphere on his tomb, as this was his favorite mathematical proof. Most famously, he wrote two volumes on the geometry of the sphere and the cylinder he proved that the volume of a sphere was two thirds that of a cylinder. He moved to Alexandria to study mathematics, but returned to Syracuse where he spend the rest of his life.Īrchimedes produced a large amount of work in math, especially in geometry. He was born in Syracuse, Sicily in 287 BC. Archimedes of Syracuse was a Greek mathematician, inventor and scientist.
