The actual state of our knowledge is always provisional and … there must be, beyond what is actually known, immense new regions to discover.

Louis de Broglie (15 August 189219 March 1987) was a French physicist became a Nobel laureate in 1929 for his theory on wave–particle duality.

It seems a little paradoxical to construct a configuration space with the coordinates of points which do not exist.

  • The history of science shows that the progress of science has constantly been hampered by the tyrannical influence of certain conceptions that finally came to be considered as dogma. For this reason, it is proper to submit periodically to a very searching examination, principles that we have come to assume without any more discussion.
  • Two seemingly incompatible conceptions can each represent an aspect of the truth ... They may serve in turn to represent the facts without ever entering into direct conflict.

    • Assuming that the particle has an internal vibration which allows to assimilate it to a small clock, I supposed that the clock was traveling with the wave in such a way that its internal vibration remained constantly in phase with the wave's : this is the phase matching postulate.
