energy on the atomic and sub atomic
level. The nature and behavior of
matter and energy at that level is sometimes
referred to as quantum
physics and quantum mechanics. In 1900,
physicist Max_Planck presented
his quantum theory to the German
Physical Society. Planck had sought to
discover the reason that radiation from a
glowing body changes in color from
red, to orange, and, finally, to blue as its
temperature rises. He found that by
making the assumption that energy
existed in individual units in the same
way that matter does, rather than just as a
constant electromagnetic wave - as had been
formerly assumed - and was
therefore quantifiable, he could find the
answer to his question. The existence of
these units became the first assumption
of quantum theory. Planck wrote a
mathematical equation
involving a figure to represent these
individual units of energy, which he
called quanta . The equation explained the
phenomenon very well; Planck
found that at certain discrete
temperature levels (exact multiples of a
basic minimum value), energy from a glowing
body will occupy different
areas of the color spectrum. Planck
assumed there was a theory yet to
emerge from the discovery of quanta,
but, in fact, their very existence implied
a completely new and fundamental
understanding of the laws of nature.
Planck won the #Nobel_Prize in Physics
for his theory in 1918, but
developments by various scientists
over a thirty-year period all contributed
to the modern understanding of quantum
theory. *The Development of Quantum Theory-

radiation itself was quantized in the

conditions, like either particles or waves. In

complementary values - such as the
position and momentum of a

measured, the more flawed will be
the measurement of the other value. This
theory became known as the uncertainty
principle, which prompted #Albert_Einstein's
famous
comment, "God does not play dice."
