3 août 1899 - -Max Planck was a German Theoretical Physicist
and considered the father of quantum theory,
as he created it in 1900. By discovering that
energy did not flow evenly but rather in packets
(which he called "quanta.") Planck created an
equation to predict this phenomenon, which
includes a constant now known as "Planck's
constant." Planck's discovery ended what many
people now call "classical physics" and began
the study of quantum physics.
