may 31, 465 BC - 465 BC:
A Greek philosopher, Democritus,
also known as the father, of atomic
thought came up of a theory in
465BC. He hypothesized that
the universe is composed of two
elements: the atoms and the
void in which they exist and move.
He deduced that all matter is made of
an infinite amount of invisible atoms
that vary in size, density, shape, and temperature.
