			==Criticisms and developments from researchers on this wiki==

			De Broglie's matter waves are a live subject of re-examination among researchers catalogued here — both as to their physical basis and as to whether the standard derivation is well founded:

			* ''[[Derivation of de Broglie's Relations from Newton?s Second Law\|Derivation of de Broglie's Relations from Newton's Second Law]]'' and ''[[Origin of the Compton and de Broglie Relations]]'' — seek classical or mechanical foundations for relations usually presented as irreducibly quantum.
			* ''[[The de Broglie Relations: Lorentz Invariance and Photons]]'' — examines how the relations behave under Lorentz transformation.
			* ''[[De Broglie Wave Physics]]'' and ''[[On Universal Fliuds and De Broglie Waves]]'' — treat the matter wave as a real disturbance in a physical medium rather than a probability amplitude.
			* ''[[The Aarau Question and the de Broglie Wave]]'' — revisits the wave concept through the thought experiment that preoccupied the young Einstein.
			* ''[[Laboratory-Scale Test of de Broglie?s Tired-Photon Model\|Laboratory-Scale Test of de Broglie's Tired-Photon Model]]'' — proposes an experimental test of a photon-energy-loss model in de Broglie's tradition.
			* ''[[Quantum Mechanics Differential Equations Based on the Focal-Radius Of A Particle Instead of the De Broglie Wavelength]]'' — proposes replacing the de Broglie wavelength as the basic quantity.

			The recurring theme is that de Broglie's own realist instinct — that the wave is something physically present, not merely a calculational device — remains the more promising line, and that it was set aside prematurely along with his pilot-wave programme. See [[De Broglie–Bohm theory]] and [[Quantum mechanics]].

'''Louis Victor Pierre Raymond, 7th duc de Broglie''' (15 August 1892 – 19 March 1987) was a French theoretical physicist who, in his 1924 doctoral thesis, proposed that all matter has wave properties — the '''de Broglie hypothesis''', which established wave–particle duality as a central feature of quantum theory. After the wave behaviour of electrons was confirmed experimentally in 1927, he was awarded the '''Nobel Prize in Physics in 1929'''.

De Broglie is of particular interest to the critical-thinkers community documented on this wiki because of his lifelong search for a '''causal''', physically intelligible account of quantum mechanics — an alternative to the probabilistic Copenhagen interpretation that remains the mainstream view.

==Matter waves==

De Broglie's thesis extended to matter the wave–particle duality that Einstein had proposed for light, associating with every particle a wavelength inversely proportional to its momentum. The idea was quickly vindicated by electron-diffraction experiments and became foundational to wave mechanics, directly influencing Schrödinger's formulation.

==The pilot wave and the double solution==

At the 1927 Solvay Conference, de Broglie presented a '''pilot-wave''' interpretation, in which particles are real entities guided by an associated physical wave — a causal picture in which quantum outcomes are not irreducibly random. Faced with strong criticism, he set the approach aside for some years.

After David Bohm independently revived a causal, hidden-variable interpretation in 1952, de Broglie returned to the programme, developing it further as his '''theory of the double solution'''. In this later work he collaborated closely with his assistant [[Jean Pierre Vigier]], who went on to become a leading proponent of a stochastic, causal interpretation of quantum mechanics in his own right. This lineage — de Broglie, Bohm, Vigier — is the principal alternative tradition to the Copenhagen interpretation, and much of the work catalogued on this wiki descends from it.

==Legacy==

De Broglie was a member and later Perpetual Secretary of the French Academy of Sciences. The '''Fondation Louis de Broglie''' was established in his honour, and its journal, ''[[Annales de la Fondation Louis de Broglie]]'', remains an important venue for foundational and dissident work in physics; a number of papers catalogued on this wiki were published there.
