Louis+de+Broglie



=Biography= Louis de Broglie was born to a noble family in Dieppe, France on August 15, 1895. He had originally intended on a career in humanities and ahead a degree in history. He later became interested in math and science and studied for a science degree. Earned his doctorate for his work on the wave-particle duality theory of matter. He won a Nobel Prize for for his research from the de Broglie hypothesis

=Contributions to Chemistry= Matter and Wave-Particle Duality: "The fundamental idea of [my 1924 thesis] was the following: The fact that, following Einstein's introduction of photons in light waves, 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... My essential idea was to extend to all particles the coexistence of waves and particles discovered by Einstein in 1905 in the case of light and photons." "With every particle of matter with mass **m** and velocity **v** a real wave must be 'associated'", related to the momentum by the equation: 

Duality of the Laws of Nature: Far from claiming to make "the contradiction disappear" which Max Born thought could be achieved with a statistical approach, de Broglie extended wave–particle duality to all particles (and to crystals which revealed the effects of diffraction) and extended the principle of duality to the laws of nature.

His last work made a single system of laws from the two large systems of thermodynamics and of mechanics.

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. It is also close to that of Leibniz who posited the necessity of "architectonic principles" to complete the system of mechanical laws.

However, according to him, there is less duality, in the sense of opposition, than synthesis (one is the limit of the other) and the effort of synthesis is constant according to him, like in his first formula, in which the first member pertains to mechanics andthe second to optics:
