AS EARLY AS BCE, the Babylonians had dating martin d18 a sexagesimal number system based on writing numbers in multiples of 60 and the principle of position where numbers in different positions represent different orders of magnitude.
By BCE they sometimes used a marker to indicate a null value zero. The screw pump or Archimedes Screw is a cylindrical pump with a central shaft surrounded dating martin d18 inner blades in the shape of a spiral and encased in wood.

Reduced pressure on the opposite side opens the valve to let more water in. He developed this idea to produce the Ctesibian device, a two-chamber force pump that used pistons attached to a rocker to create pressure. With the chambers of the device immersed in water, the rocker was moved up and down, alternately sucking water into one chamber and forcing it out of the other. Another inventor, and philosopher, Archimedes — BCE was also one of the greatest mathematicians of ancient Greece.
In On the Measurement of a Circle he presented a method for calculating the area and reduced pressure shuts outlet valve
