Archimedes' screw, also called the Archimedean screw or screwpump, is a machine historically used for transferring water from a low-lying body of water into irrigation ditches. The screw pump is commonly attributed to Archimedes on the occasion of his visit to Egypt, but this tradition may reflect only that the apparatus was unknown to the Greeks before Hellenistic times and introduced in his lifetime by unknown Greek engineers. Some writers have suggested that the device may have been in use in Assyria some 350 years earlier.
Archimedes' screw was operated by hand and could raise water efficiently

The son of a salesman who later operated an electrochemical factory, Einstein was born in the German Empire, but moved to Switzerland in 1895, forsaking his German citizenship the following year. Specializing in physics and mathematics, he received his academic teaching diploma from the Swiss Federal Polytechnic School in Zürich in 1900. The following year, he acquired Swiss citizenship, which he kept for his entire life. After initially struggling to find work, from 1902 to 1909 he was employed as a patent examiner at the Swiss Patent Office in Bern. (Full article...)
Classical physics is usually concerned with everyday conditions: speeds are much lower than the speed of light, sizes are much greater than that of atoms, yet very small in astronomical terms. Modern physics, however, is concerned with high velocities, small distances, and very large energies.
