| Quanta Who1 #722510 A quantum (a Latin word meaning "how many") is the smallest indivisible unit which can be gained, lost or exchanged, regarding energy, movement quantity or mass. The concept is fundamental in quantum theory, which was introduced in the early 20th century and led to quantum mechanics. This theory opposes the classical mechanics, which states that energy and other physical properties can be exchanged in arbitrarily small amounts. | |
