## Archimedes

Archimedes of Syracuse was a Greek scientist. He was an inventor, an astronomer, and a mathematician. He was born in the town of Syracuse in Sicily. His father was Phidias, an astronomer, and he may have been in the family of a king of Syracuse. Syracuse was a rich Greek city, on the seashore in Sicily. When Archimedes was about ten years old, he left Syracuse to study in Alexandria, Egypt. He was in the school of Euclid, a famous mathematician. Not much is known about the personal life of Archimedes, for example, whether he was married or if he had children. When the Romans invaded Syracu ...

## Archimedean solid

In geometry, an Archimedean solid is a convex shape which is composed of polygons. It is a polyhedron, with the following properties: The shape is neither a platonic solid, nor a prism, nor an antiprism. All the corners of the shape look the same Each face is made of a regular polygon Depending on the way there are counted, there are thirteen or fifteen such shapes. Of two of these shapes, there are two versions, which cannot be made congruent using rotation. The Archimedean solids are named after the Ancient Greek mathematician Archimedes, who probably discovered them in the 3rd century B ...

## Archimedes number

The Archimedes number is named after the Greek Archimedes. In viscous fluid dynamics, the Archimedes number Ar is used when the motion of fluids is affected by density differences. It is a dimensionless number, the ratio of gravitational forces to viscous forces. The relationship and has the form: A r = g L 3 ρ ℓ ρ − ρ ℓ μ 2 {\displaystyle \mathrm {Ar} ={\frac {gL^{3}\rho _{\ell }\rho -\rho _{\ell }}{\mu ^{2}}}} where: ρ ℓ {\displaystyle \rho _{\ell }} is the density of the fluid, kg/m 3, g {\displaystyle g} is the local external field for example gravitational acceleration, m/s 2, ρ {\dis ...

## Archimedes principle

Archimedes principle is named after Archimedes of Syracuse, the first to discover this law. When he did, he ran naked out of his bathtub. Archimedes principle relates buoyancy to displacement.
