**Born:** Syracuse, Italy

**Died:** Syracuse, Italy

**Nationality:** Greek

**Parents:** Phidias

**Fields:** Mathematics, Physics, Engineering, Astronomy, Invention

**Known for:** Archimedes’ principle, Archimedes’ screw, hydrostatics, levers, infinitesimals, Neuseis constructions

- Archimedes was born in the Greek city of Syracuse, on the island of Sicily, in 287 B.C. He was the son of Phidias, the astronomer and mathematician.
- What we know of Archimedes’ life comes from his extent writings, and from the histories authored by Plutarch, Cicero, and other historians several centuries after his death.
- Due to the length of time between Archimedes’ death and his biographers’ accounts, as well as inconsistencies among their writings, details of his life must remain subject to question.
- Plutarch records that Archimeds was relative of King Hieron, but Cicero claims he was of low birth. It is believed he obtained his early schooling in Syracuse, then traveled to Alexandria to study with Conon, the Eygyptian mathematician and astronomer.
- Archimedes’ contributions to mathematical knowledge were diverse.
- On the subject of plane geometry three of the treatises he wrote havesurvived, Measurment of a Circle, Quadrature of the Parabola, and On Spirals.
- Archimedes dealt with the topic of solid geometry in his writings On the Sphere and Cylinderand On Conoids and Spheroids.
- On the Sphere and Cylinder contains several famous proofs, including his demonstration that the volume of a sphere is equal to 4/3 r3.
- On the subject of arithmetic Archimedes wrote several essays, of which only The Sand Reckoner remains.
- Archimedes was famous for another complicated arithmetic puzzle called the Cattle Problem, in which one had to determine the number of bulls and cows of various colors, given that each cattle color was represented in a particular ratio to the others. There are an infinite number of possible solutions to the problem, but deriving them was especially challenging to the ancient Greeks, who had no knowledge of algebra.
- According to the ancient historians, Archimedes was frequently called upon by King Hieron to solve practical problems.
- Archimedes recognized the mechanical advantage that could be gained by using levers, and it is said he boasted that with a long enough lever he could move the Earth.
- He determined the inverse mathematical relationship between the effort required to raise a load with a lever and the distance of the load from the lever’s pivot point or fulcrum.

Archimedes was also interested in astronomy and made several accomplishments in this field. He built a device to estimate the size of the sun and constructed a model plametarium to demonstrate the motion of the planets.
