The atoms are in ceaseless motion from the surrounding void and collide with each other like billiard balls, very similar to the trendy kinetic principle of gases. Nevertheless, the requirement for the void (or vacuum) in between the atoms lifted new queries that could not be quickly answered. Because of this, the atomist photograph was rejected by Aristotle plus the Athenian college in favour of your notion that subject is continuous. The theory Nonetheless persisted, and it reappeared four hundred decades later from the writings from the Roman poet Lucretius, in his get the job done De rerum natura
