Archimedes, (287*-212 BC) is a Greek mathematician, physicist, and inventor. Archimedes was born in Syracuse, Sicily, a Greek colony, at some time near 287 BC. He invented many things, including the Archimedes screw, which can be used to bilge or transfer water from rivers to canals, or to irrigate fields. He also was a great mathematician and scientist, stating that if you dropped some amount of mass in a body of water, the water would be displaced by the amount of mass there wthis Emailas in the object. Archimedes also stated that you could multiply work efficiency by placing things on a lever, hence Archimedes favorite saying “Give me a place to stand on, and I will move the Earth.” Another theory he made was the surface area of a circle is 2/3 of the surface area of a cylinder the same height and diameter. He had a diagram of this in his tomb at his request. He also published many works, and was one of the most important people in history. He died in the Second Punic War, during the capture of Syracuse, when a soldier killed him against his commander’s orders. His last known words were “Do not disturb my circles!”, said to the Roman soldier who had come to ask him to go see the Roman commander Marcus Marcellus. Archimedes I. Introduction II. Biography a.

 * According to reports

Archimedes was an important part of the world’s development, and he is often placed as one of the worlds most important scientists. He developed many inventions and the great ship //Syracrusia//. Take a look at Archimedes many inventions and stories. Archimedes was born in Syracruse, a colony at the time, in 287 B.C. He died during the siege of Syracruse by Romans in 212 B.C. during the second Punic War by a Roman soldier. He reportedly said “Do not disturb my circles.” when a soldier barged into his room. The Roman killed Archimedes, despite his orders not to harm him from his commander, Marcellus. On his tomb is a sphere with a cylinder the same height and diameter as the circle at his request. Very few biographies still exist about him, despite all the popularity he gained, and the number of biographies made about him. Archimedes contributed many things to mathematics, including the most accurate estimation of pi at the time. Another important discovery he made was that the surface area of a sphere can be measured by measuring the surface area of a cylinder with the same height and size, then multiplying that by 2/3. Archimedes also made the law of buoyancy, and did a lot of work with levers, stating the famous phrase, “Give me a fulcrum, and I will move the earth.” among many other inventions. Archimedes also invented many important inventions, some of which are still used in developing countries. The Archimedes screw, for example, was made so that the //Syracrusia// would not take on too much water. It consisted of a screw inside a tube. It can be used to irrigate fields and transfer river water to canals. It also has been noted that it is like the irrigation system used in the Hanging Gardens of Babylon. Archimedes invented the Claw of Archimedes; a grappling hook connected to a crane that, when a ship stared to dock, picked up a ship and dropped it, capsizing the ship. This was used in the siege of Syracruse. Archimedes also invented an improvement to the catapult, which dropped a ball into a basket for every mile the projectile would travel. With every great person there is, there are great stories. This is true for Archimedes as well, like when the king asked Archimedes to make something akin to a cruise ship, and so Archimedes did. The ship he made, the //Syracrusia//, was capable of holding 600 people and had a gym, an altar to Aphrodite, and garden decorations. Another story is during the siege of Syracruse; Archimedes took some mirrors and men, and focused the mirrors on one single point on a Roman ship, the ship caught on fire, and they repeated the process many times. The last story is said when Archimedes was asked to determine if the king’s crown was solid gold. When Archimedes was taking a bath, he realized as he got in that the water level rose. He then got up shouting, “Eureka! I‘ve got it!” In his excitement he had forgot to put on his clothes, so he ran to the palace naked. You have now seen many famous parts of Archimedes life, and you have a better understanding of what he did to make himself immortal to the masses. Archimedes indeed was one of the brightest minds in history.
