Louis de Broglie Quotes

Louis Victor Pierre Raymond de Broglie, 7th duc de Broglie was a French 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.

The 1925 pilot-wave model, and the wave-like behaviour of particles discovered by de Broglie was used by Erwin Schrödinger in his formulation of wave mechanics. The pilot-wave model and interpretation was then abandoned, in favor of the quantum formalism, until 1952 when it was rediscovered and enhanced by David Bohm.Louis de Broglie was the sixteenth member elected to occupy seat 1 of the Académie française in 1944, and served as Perpetual Secretary of the French Academy of Sciences. De Broglie became the first high-level scientist to call for establishment of a multi-national laboratory, a proposal that led to the establishment of the European Organization for Nuclear Research .

Famous Louis de Broglie Quotes

“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.”

Will Quantum Physics Remain Indeterministic, in
Context: 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.

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

La nouvelle dynamique des quanta (1928), translation by [Bacciagaluppi, G., Valentini, A., Quantum Theory at the Crossroads: Reconsidering the 1927 Solvay Conference, Cambridge University Press, 2009, 0521814219, 380]

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

Foreword of book by [David Bohm, Causality and Chance in Modern Physics, Routledge, 1984, 0415174406, x]

“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.”

Admettant que la particule possède une vibration interne qui permet de l'assimiler à une petite horloge, je supposais que cette horloge se déplaçait dans son onde de façon que sa vibration interne reste constamment en phase avec celle de l'onde : c'est le postulat de l'accord des phases.
Sur les véritables idées de base de la mécanique ondulatoire, Louis de Broglie, C. R. Acad. Sci., 277, série B, 1973, p. 71-73.
