The Hellenistic inventor and mathematician you are referring to is Archimedes. He is well-known for his experiments with levers and for designing the Archimedean screw, a machine used for raising and transporting water. Additionally, Archimedes formulated important mathematical principles, including formulas for calculating the surface area and volume of a sphere. His contributions laid the groundwork for many fields in mathematics and engineering.
