He inspired the formation of the International Academy of Quantum Molecular Science and was an early member. This theory set the basis of wave mechanics. This theory, which dates from , introduces the idea that the photon is equivalent to the fusion of two Dirac neutrinos. Internet URLs are the best. Retrieved 30 June De Broglie derived the formula for their wavelength, which showed that, for example, for electrons accelerated by 60, volts or 60 kilovolts….

In addition to strictly scientific work, de Broglie thought and wrote about the philosophy of science , including the value of modern scientific discoveries. However, until the end of his life de Broglie returned to a direct and real physical interpretation of matter-waves, following the work of David Bohm. This article needs additional citations for verification. This theory, which dates from , introduces the idea that the photon is equivalent to the fusion of two Dirac neutrinos. Thank you for your feedback. Unfortunately, our editorial approach may not be able to accommodate all contributions. With the outbreak of the First World War in , he offered his services to the army in the development of radio communications.

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.

This theory, which dates fromintroduces the idea that the photon is equivalent to the fusion of two Dirac neutrinos. Albert Einstein, German-born physicist who developed the special and general theories of relativity and….

It shows thesos the movement of the center of gravity of these two particles obeys the Maxwell equations —that implies that the neutrino and the photon both have rest masses that are non-zero, though very low. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. Any text you add should be original, not copied from other sources.

This included the wave—particle duality theory of matter, based on the work of Max Planck and Albert Einstein on light. Louis occasionally joined his brother in his work, but it was the purely conceptual side of physics that attracted him. Hestenes, OctoberThe Zitterbewegung interpretation of quantum mechanics, Foundations of Physics, vol.

We welcome suggested improvements to any of our articles. In this thesis de Broglie 19224 his revolutionary theory of electron waves, which he had published earlier in scientific journals. The central question for him was whether the statistical considerations that are fundamental to atomic physics reflect an ignorance of underlying causes or whether they express all nroglie there is to be known; the latter would be the case if, as some believe, the act of measuring affects, and is inseparable from, what is measured.

From a philosophical viewpoint, this theory of matter-waves has contributed greatly to the ruin of the atomism of the past. History at your fingertips.

I think that, of all the ideas that I’ve introduced in quantum theory in these past years, it’s that idea that is, by far, the most important and the most profound. He became the 7th duc de Broglie in upon the death without heir of his older brother, Maurice, 6th duc de Brogliealso a physicist. De Broglie had intended a career in humanitiesand received his first degree in history. Bulletin of the Atomic Scientists. Help us improve this article! As a consequence of its great impact, this theory brings back the uncertainty principle to distances around rboglie of action, distances corresponding to reductions in entropy.


It is an attempt to bring together the three furthest principles of physics: Please help improve this article by adding citations to reliable sources. Retrieved 30 June Thank You for Your Contribution! For other members of the family, see House of Broglie. This concept is known as the de Broglie hypothesis, an example of wave—particle dualityand forms a central part of the theory of quantum mechanics.

After a period of severe conflict, he declined the research project in French history that he had been assigned and chose for his doctoral thesis a subject in physics. By using this site, you agree to the Terms of Use and Privacy Policy.

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. In addition to winning the Nobel Prize for Physics, de Broglie received, inthe Kalinga Prize, awarded by the United Nations Economic and Social Councilin recognition of his writings on science for the general public.
