Mathematician:Archimedes of Syracuse

Mathematician
Known as Archimedes of Syracuse.

Greek mathematician, physicist, astronomer, engineer and general all-round inventor.

Perfected the method of exhaustion. Considered by many (with some justification) to be the greatest mathematician, inventor and physicist of the ancient world.

Other achievements:
 * Discovered the principle of the lever
 * Originated the concept of the center of gravity, and found them for several plane figures
 * With his machines, he held off several attacks by the Romans under Marcellus

Nationality
Greek

History

 * Born: c. 287 BCE in Syracuse in Magna Graecia (in Sicily, now part of Italy)
 * Died: c. 212 BCE in the Second Punic War. Supposed to have been by a drunken Roman soldier because either:
 * He was contemplating a problem in geometry and was unwilling to be disturbed to answer a summons from the Roman general who had captured the city;
 * He was killed trying to surrender to the Romans, and a soldier killed him to plunder his mathematical instruments, which the soldier thought were valuable.

 * (which includes the calculation of the volume of a sphere)
 * On the Sphere and Cylinder (2 books)
 * On Conoids and Spheroids
 * On Spirals
 * On Floating Bodies (2 books)
 * Measurement of a Circle
 * On Sphere-making (now lost, believed to have dealt with the techniques for building his solar system model)
 * On Sphere-making (now lost, believed to have dealt with the techniques for building his solar system model)

The following works appear no longer to be with us:
 * A work on semi-regular polyhedra, mentioned by
 * A work on the number system proposed in (mentioned by Archimedes himself)
 * On balances and levers mentioned by
 * A treatise about mirrors, mentioned by

Commentaries of On Plane Equilibriums, On the Sphere and Cylinder and Measurement of a Circle were written by.

Notable Quotes

 * Give me a place to stand on, and I can move the earth.


 * Eureka, eureka!


 * Do not disturb my circles.


 * I do not want to be thought to have uttered vain words, but equally because I am persuaded that it will be of no little service to mathematics; for I apprehend that some, either of my contemporaries or of my successors, will, by means of the method when once established, be able to discover other theorems in addition, which have not yet occurred to me.
