But why is this reduction to discrete bits necessary. The first, which follows on directly from the famous doctoral thesis by L.

In this sense, if it were not for relativistic effects, quantum wave mechanics would not exist. A Critical Study, Elsevier, Amsterdam, Rest energy plus kinetic energy in the kinematic sense p the momentum, displaystyle gamma the Lorentz factor, c the speed of light, and the speed as a fraction.

But in the account of quantum mechanics, a 'point' refers to a configuration of the system at an instant of time, every particle of the system being in a sense present in every 'point' of configuration space, each particle at such a 'point' being located possibly at a different position in ordinary physical space.

He has been a member of the Bureau des Longitudes since 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. During this period he was stationed at the Eiffel Tower, where he devoted his spare time to the study of technical problems.

When Boltzmann and his continuators developed their statistical interpretation of Thermodynamics, one could have considered Thermodynamics to be a complicated branch of Dynamics. The ideas set out in that work, which first gave rise to astonishment owing to their novelty, were subsequently fully confirmed by the discovery of electron diffraction by crystals in by Davisson and Germer; they served as the basis for developing the general theory nowadays known by the name of wave mechanics, a theory which has utterly transformed our knowledge of physical phenomena on the atomic scale.

At these temperatures, the thermal de Broglie wavelengths come into the micrometre range. The Current Interpretation of Wave Mechanics: One option is to go against the mathematical grain and to simply look at the problem the other way round, thus reversing the order of derivation here: It was not translated into English until nearly 80 years later.

During this period he was stationed at the Eiffel Tower, where he devoted his spare time to the study of technical problems. Nothing happens; there is being but no becoming.

The angular dependence of the diffracted electron intensity was measured, and was determined to have the same diffraction pattern as those predicted by Bragg for x-rays. If one wishes to calculate the probabilities of excitation and ionization of atoms. Duality of the laws of nature[ edit ] 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.

It was later edited and republished in Nobel Lectures. In truth, however, a complete unification of the two conceptions has not yet been achieved. Generalization of the principle of least action[ edit ] In the second part of his thesis, de Broglie used the equivalence of the mechanical principle of least action with Fermat's optical principle: Therefore, the presence of any diffraction effects by matter demonstrated the wave-like nature of matter.

Using the same notation as above. In addition, he believed that the true mass of particles is not constant, but variable, and that each particle can be represented as a thermodynamic machine equivalent to a cyclic integral of action.

He has made major contributions to the fostering of international scientific co-operation. Physical objects are not in space, but these objects are spatially extended.

While taking an interest in the experimental work carried out by his elder brother, Maurice, and co-workers, he specialized in theoretical physics and, in particular, in the study of problems involving quanta.

Louis de Broglie was born to a noble family in Dieppe, Seine-Maritime, younger son of Victor, 5th duc de Broglie. He became the 7th duc de Broglie in upon the death without heir of his older brother, Maurice, 6th duc de Broglie, also a physicist.

Louis de Broglie hypothesized that any particle should also exhibit such a duality. De Broglie, in his PhD thesis, proposed that just as light has both wave-like and particle-like properties, electrons also have wave-like properties.
