De broglie thesis english translation

But this is a description of the general algebraic procedure, no matter whether an image is used to assist the procedure or not. After the maintaining of his thesis and while continuing to publish original work on the new mechanics, Louis de Broglie took up teaching duties.

Originally, de Broglie thought that real wave i. Its circuits set up, for a specific calculation task. The physical reasoning for this was first recognized by Einstein. Nothing happens; there is being but no becoming. In contrast, these ideas are so expressed in the classical wave account, through the Green's functionthough it is inadequate for the observed quantal phenomena.

He has been a member of the Bureau des Longitudes since Read more Debroglie thesis where v is the velocity of the particle regardless of wave behavior. He has been a member of the Bureau des Longitudes since Sincetogether with young colleagues, Louis de Broglie has resumed the study of an attempt which he made in under the name of the theory of the double solution to give a causal interpretation to wave mechanics in the classical terms of space and time, an attempt which he had then abandoned in the face of the almost universal adherence of physicists to the purely probabilistic interpretation of BornBohrand Heisenberg.

At the same time George Paget Thomson at the University of Aberdeen was independently firing electrons at very thin metal foils to demonstrate the same effect. This conceptual difference entails that, in contrast to de Broglie's pre-quantum mechanical wave description, the quantum mechanical probability packet description does not directly and explicitly express the Aristotelian idea, referred to by Newton, that causal efficacy propagates through ordinary space by contact, nor the Einsteinian idea that such propagation is no faster than light.

This hypothesis is the basis of our theory. There is no explicit definite indication that, at an instant, this particle is 'here' and that particle is 'there' in some separate 'location' in configuration space.

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: Yet others propose some intermediate entity that is neither quite wave nor quite particle but only appears as such when we measure one or the other property.

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 this sense, if it were not for relativistic effects, quantum wave mechanics would not exist.


A Critical Study, Elsevier, Amsterdam, In short, wherever we succeed in giving a mechanical explanation, we observe a fairly strict parallelism between the physiological and the psychological series, and we need not be surprised at it, since explanations of this kind will assuredly not be met with except where the.

Some theories treat either the particle or the wave aspect as its fundamental nature, seeking to explain the other as an emergent property. It was not translated into English until nearly 80 years later. To view the animations, click on one of the images below. His last work made a single system of laws from the two large systems of thermodynamics and of mechanics: These ideas may be expressed in ordinary language as follows.

Atom optics Experiments with Fresnel diffraction [8] and an atomic mirror for specular reflection [9] [10] of neutral atoms confirm the application of the de Broglie hypothesis to atoms, i. The surface passing through the centre of gravity of the weights would be a plane oscillating up and down.

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.

Displaystyle lambda frac hpfrac hmv. However, this generalization was statistical and was not approved of by de Broglie, who said "that the particle must 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.

More recent experiments prove the quantum nature of molecules made of atoms and with a mass of 10, amu. This wavefunction gives an appearance of wave behavior to matter, without making real physical waves appear.

Ordinary physical waves are characterized by undulating real-number 'displacements' of dimensioned physical variables at each point of ordinary physical space at each instant of time.

Prince Louis-Victor Pierre Raymond de Broglie

All matter can exhibit wave -like behavior. During this period he was stationed at the Eiffel Tower, where he devoted his spare time to the study of technical problems. Davisson—Germer experiment and Electron diffraction In at Bell Labs, Clinton Davisson and Lester Germer fired slow-moving electrons at a crystalline nickel target.

In the account of ordinary physical waves, a 'point' refers to a position in ordinary physical space at an instant of time, at which there is specified a 'displacement' of some physical quantity. He was then conscripted for military service and posted to the wireless section of the army, where he remained for the whole of the war of All the weights on springs have the same period; let us set them in motion with identical amplitudes and phases.

However, sometimes it is hard to recognize the value of a friend and see. Henri Bergson's doctoral thesis was published in France inand much later translated into English under the title Time and Free contained basic ideas that Bergson developed further in Matter and Memory and Creative Evolution especially his idea of duration.

Mar 19,  · The concept that matter behaves like a wave is also referred to as the de Broglie hypothesis () due to having been proposed by Louis de Broglie in De Broglie's thesis started from the hypothesis, English translation by A.F.

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.
