From the Broglie family , whose name is taken from a small town in Normandy , have come high-ranking soldiers, politicians, and diplomats since the 17th century. Incidentally, this rejection of the hypothesis of a massless photon enabled him to doubt the hypothesis of the expansion of the universe. When Boltzmann and his continuators developed their statistical interpretation of Thermodynamics, one could have considered Thermodynamics to be a complicated branch of Dynamics. Sir Isaac Newton, English physicist and mathematician, who was the culminating figure of the scientific…. The de Broglie—Bohm theory is today the only interpretation giving real status to matter-waves and representing the predictions of quantum theory.

In his later career, de Broglie worked to develop a causal explanation of wave mechanics, in opposition to the wholly probabilistic models which dominate quantum mechanical theory; it was refined by David Bohm in the s. With the ds of the First World War inhe offered his services to the army in the development of radio communications. De Broglie thesi awarded a post as counselor to the French High Commission of Atomic Energy in for his efforts to bring industry and science closer together.

The fact that, following Einstein ‘s introduction of photons in light ghesis, one knew that light contains particles which are concentrations of energy incorporated into the wave, suggests that all particles, like the electron, must be transported by a wave into which it is incorporated See de Broglie wave.

This theory set the basis of wave mechanics. Physics Curiosities, Oddities, and Novelties. Incidentally, this rejection of the hypothesis of a massless photon enabled him to doubt the hypothesis of the expansion of the universe.

However, this generalization was statistical and was not approved of by de Broglie, who said “that the particle dee be the seat of an internal periodic movement and that it must move in a wave in order to remain in phase with it was ignored by the actual physicists [who are] wrong to consider a wave propagation without localization of the particle, which was quite contrary to my original ideas. The de Broglie pilot wave theory and the further development and new insights arising out of itFoundations of Physics, volume 12, number 10,Appendix: Afterwards he turned his attention toward mathematics and physics and received a degree in thhesis.

While attempts at verifying the internal clock hypothesis and measuring clock frequency are so far not conclusive, [17] recent experimental data is at least compatible with de Broglie’s conjecture.

My essential idea was to extend to all particles the coexistence of waves and particles discovered by Einstein in in the case of light and photons. The de Broglie—Bohm theory is today the only interpretation giving real status to matter-waves and representing the predictions of quantum theory. The notion that matter on the atomic scale might have the properties of a wave was rooted in a proposal Einstein had made 20 years before.

That idea seems to match the continuous—discontinuous duality, since its dynamics could be the limit of its thermodynamics when transitions to continuous limits are postulated. In addition, he believed that the true mass of particles is not boglie, but variable, and that each particle can be represented as a thermodynamic machine equivalent to a cyclic integral of action.

Originally, de Broglie thought that real wave i. Duke of Broglie — That a photon is not quite massless is imposed by the coherence of his theory.

De Broglie’s final idea was the hidden thermodynamics of isolated particles. Einstein had suggested that light of short wavelengths might under some conditions be observed to behave as if it were composed of particles, bgoglie idea that was confirmed in Biographical Memoirs of Fellows of the Royal Society.
