The concept of Atomicity is widespread in between atomic transactions and atomic functions, but they are frequently related to diverse domains.

The atoms are in ceaseless motion through the bordering void and collide with one another like billiard balls, very like the fashionable kinetic theory of gases. Having said that, the necessity to get a void (or vacuum) concerning the atoms elevated new questions that would not be very easily answered. For this reason, the atomist photo was rejected by Aristotle along with the Athenian school in favour with the notion that issue is continuous.
