Authors: J. Bar-Sagi The electromagnetic wave quantum-energy
depends only on its frequency, not on the emitting system's
radiation power. The proportionality constant between the
frequency and the quantumenergy of the electromagnetic wave, the
Planck's constant is in the essence of quantum mechanics. This
constant is known experimentally but till now there was no clue
for calculating its value on a theoretical basis. In the present
work a methodology for calculating a lower bound for Planck's
constant is presented, based on simple principles. In order to
get a reasonable good lower bound it is necessary to have a
model of a relativistic oscillator whose period is independent
of its energy and which efficiently radiates electromagnetic
energy. It is highly desired that the mathematics involved is
simple enough to enable good insight into the results. Such a
model can also be used for other investigations, and therefore,
in this work a potential that conserves the vibration period of
symmetric oscillators at re
