The Answer is Archimedes (c. 287 BC – c. 212 BC) was an ancient Greek mathematician, physicist, engineer, inventor, and astronomer. He is considered one of the greatest mathematicians of all time and has made significant contributions to the fields of mathematics, physics, engineering, and astronomy. Some of his most notable contributions include:

1. Archimedes' Principle: This principle states that a body submerged in a fluid experiences a buoyant force equal to the weight of the fluid it displaces. This principle is fundamental in hydrostatics and has numerous applications, including the design of ships and submarines.

2. Archimedes' Screw: This is a machine historically used for transferring water from a low-lying body of water into irrigation ditches. The screw consists of a helical surface surrounding a central cylindrical shaft. As the shaft turns, the bottom end scoops up a volume of water, which is then transferred to the top and out of the device.

3. Mathematical Discoveries: Archimedes made significant contributions to geometry, including the method of exhaustion for calculating areas and volumes, and he provided an accurate approximation of pi. He also worked on the geometry of spheres and cylinders and established the relationship between the surface area and volume of a sphere and its circumscribing cylinder.

4. Archimedes' Claw: Also known as the "ship shaker," this was a weapon designed to defend the city of Syracuse from naval attack. It purportedly consisted of a crane-like arm from which a large metal grappling hook was suspended. When the claw was dropped onto an attacking ship, the arm would lift the ship out of the water, causing it to capsize or be otherwise damaged.

5. Contributions to Mechanics: Archimedes is credited with formalizing the concept of the lever and is famously quoted as saying, "Give me a place to stand, and I shall move the Earth with it." This is a reference to the principle of leverage, which he described in his work "On the Equilibrium of Planes."

Archimedes' work laid the foundation for many areas of modern science and engineering, and his methods anticipated the integral calculus 2,000 years before Newton and Leibniz developed it. His inventions and mathematical theorems have had a lasting legacy, and his name is synonymous with inventive genius and the power of scientific inquiry.
