    Democritus
    The theory of Democritus held that everything is composed of "atoms",
    1. Which are physically, but not geometrically, indivisible
    2. That between atoms, there lies empty space
    3. That atoms are indestructible, and have always been and always
    will be in motion
    4. That there is an infinite number of atoms and of kinds of atoms,
    which differ in shape and size
