What is Democritus atomos theory?
His famous disciple, Democritus of Abdera, named the building blocks of matter atomos, meaning literally “indivisible,” about 430 bce. Democritus believed that atoms were uniform, solid, hard, incompressible, and indestructible and that they moved in infinite numbers through empty space until stopped.
What is Democritus believe?
The theory of Democritus held that everything is composed of “atoms,” which are physically, but not geometrically, indivisible; that between atoms, there lies empty space; that atoms are indestructible, and have always been and always will be in motion; that there is an infinite number of atoms and of kinds of atoms.
What was Democritus known for?
Democritus, known in antiquity as the ‘laughing philosopher’ because of his emphasis on the value of ‘cheerfulness,’ was one of the two founders of ancient atomist theory. He elaborated a system originated by his teacher Leucippus into a materialist account of the natural world.

What was the conclusion of Democritus experiment?
Also experimented with the pressure of gasses. Conclusion: The positive charge in an atom comes from a small dense nucleus. The nucleus only has a positive charge. The negative charge comes from electrons that orbit the nucleus, each at an equal distance but on their own path.
Did Democritus break seashells?
400 B.C. Democritus He took a seashell and broke it in half. He then took half of it and broke it in half over and over and over again until he was finally left with a fine powder.
