By: MaryKate MacDonald Archimedes, 6 October 2010http://www.thedailymind.com
Born 287 B.C. in Greek colony of Syracuse on the island of Sicily
Archimedes father was Phidias who was a worthy astronomer.
Was related by blood to King of Syracuse, Hieron II.
First expedition was to the city of Alexandria, Egypt
First invention of his was Archimedes screw pump - made while he was in Egypt
Spent some time in Spain to aid the Spanish during the English Maritime War.
Early Life
Archimedes screw, 7 October 2010www.mech.upatras.gr
Returned home started to work for Hieron II
Discovered volume when King Hieron II wanted to know if his crown was pure gold. Archimedes discovered solution while taking a bath from how much water overflowed the tub.
During second Punic war in 214BC, King Hieron II asked Archimedes to make inventions of war-machines for defense against Roman general Marcellus(second Punic War laid siege to Syracuse)
Archimedes was unsure about helping because he didn’t want to hurt anyone but in the end agreed to the job.
Back in Syracuse

Archimedes claw (utilizing pulley system) – a type of crane with a hook that was able to life attacking ships partly out of the water.
Burning mirrors- Archimedes figured out you can use mirrors to concentrate the sun’s rays onto a small area and cause exposed areas to start to burn. Used to ketch attacking ships on fire.
Compound Pulley- Which is a rope, belt, or cable that runs over a wheel in a groove. They are used to change the direction of an applied force or transmit rotational motion.
Made improvements to Leonardo Da Vinci’s steam cannon, Zhang Heng’s Water clock, and the ancient catapult system
Odometer- indicates distance traveled
Inventions for the Second Punic War

Mathematics DiscoveriesOne of the first people to relate mechanics and mathematics
Discovered Powers
Determined exact value of pi between 3 10/71 and 3 1/7
Archimedes made many contributions to geometry through his work on the area of plane figures and areas and volumes of curved surfaces.
His methods started idea for calculus

Science DiscoveriesFigured out every object has a center of gravity
Discovered density and volume
Created new theorems for law of buoyancy
Archimedes Principle- an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object
Made first planetarium Archimedes Planetarium, 7 October 2010 www.cs.drexel.edu

Death A Roman Soldier killed Archimedes after the siege of Syracuse
because Archimedes would not follow the Soldier’s orders. When Marcellus, Roman commander, herd about Archimedes death, he
ordered a monument be put up in Archimedes honor.
