In the 3rd century B.C., Archimedes (A) building on the work of Thales, Pythagoras, Euclid, and all the famous mathematicians of the Ancient Greece, invented arithmetic, the geometry of forces and movement – mechanics – and a method: experimental research.
(B) He discovered the famous number π (3,1416….). His work bears indications of a certain foreknowledge of integral calculus, which was to be put into use nearly twenty centuries later. Above all, Archimedes listed and gave a full description of the five “Simple machines” known at the time: the lever, the wedge (or inclined plane), the pulley, the screw and the winch. (C) He developed the Archimedean (or hydraulic) screw and produced that other invention of vital importance, the bolt and nut.
A few years later, Ctesibius of Alexandria conceived the first gears and made a revolution counter, the ancestor of our modern speedometer.
Energy accumulators already existed, in a primitive form, the Greeks knew in 400 B.C. how to harness the forces of torsion and tension for their war machines. The Counterweight was not used until much later.
At the beginning of the 16th century, Leonardo da Vinci sketched a good many other simple machines: transmission belts and chains, conical and helical gears, as well as the universal joint.
Science seeks to learn that can be learnt while engineering seeks to do that must be done.
Department of Science & Humanities in K.G. Engineering Institute saw the light of day together with the introduction of first course in Licentiate in Engineering, that is, Licentiate in Civil Engineering in 1949.
