Louis de Broglie Quotes

Nobel laureate credited to pioneer the discovery of wave character of matter (1892–1987)

Louis de Broglie (15 August 1892 – 19 March 1987) was a French aristocrat and physicist who made groundbreaking contributions to quantum theory. In his 1924 PhD thesis, he postulated the wave nature of electrons and suggested that all matter has wave properties. This concept is known as the de Broglie hypothesis, an example of wave–particle duality, and forms a central part of the theory of quantum mechanics. De Broglie won the Nobel Prize for Physics in 1929, after the wave-like behaviour of matter was first experimentally demonstrated in 1927.

La nouvelle dynamique des quanta (1928), translation by

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.

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.

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

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