This theory, which dates from , introduces the idea that the photon is equivalent to the fusion of two Dirac neutrinos.
It shows that 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. De Broglie's final idea was the hidden thermodynamics of isolated particles. It is an attempt to bring together the three furthest principles of physics: the principles of Fermat, Maupertuis, and Carnot. In this work, action becomes a sort of opposite to entropy , through an equation that relates the only two universal dimensions of the form:. As a consequence of its great impact, this theory brings back the uncertainty principle to distances around extrema of action, distances corresponding to reductions in entropy.

Experiments came later and established the correctness of your view. His lecture notes were beautifully written, but he was deemed an uninspiring lecturer, preferring to read monotonously from his notes, although his weekly seminar in theoretical physics proved more popular. He continued his research in the field of wave mechanics, which gave rise to various applications, including the development of electron microscopes.
He later tried to develop a causal model to replace the probabilistic models of quantum mechanics, which was refined by David Bohm in the s and known as the de Broglie-Bohm theory. And he became the 7th duc de Broglie in when his brother Maurice died.
He never married, and died in Louveciennes on March 19, ; his title passed to a distant cousin. But his mark on physics remains. Historic Sites Initiative Locations and details of historic physics events.

Maurice, who was also a physicist and made notable contributions to the experimental study of the atomic nucleus, kept a well-equipped laboratory in the family mansion in Paris. Incidentally, this rejection of the hypothesis of a massless photon enabled him to doubt the hypothesis of the expansion of the universe. This included the wave—particle duality theory of matter, based on the work of Max Planck and Albert Einstein on light.
