In
physics,
Planck's law describes the
spectral density of
electromagnetic radiation emitted by a
black body in
thermal equilibrium at a given
temperature T, when there is no net flow of
matter or
energy between the body and its environment.

At the end of the 19th century, physicists were unable to explain why the observed spectrum of
black-body radiation, which by then had been accurately measured, diverged significantly at higher
frequencies from that predicted by existing theories. In 1900, German physicist
Max Planck heuristically derived a formula for the observed spectrum by assuming that a hypothetical electrically charged
oscillator in a cavity that contained black-body radiation could only change its
energy in a minimal increment, E, that was proportional to the frequency of its associated
electromagnetic wave. This resolved the problem of the
ultraviolet catastrophe predicted by
classical physics. This discovery was a pioneering insight of
modern physics and is of fundamental importance to
quantum theory.}
You really are jaw droppingly stupid!
