	Wave Mechanics; Prince Louis de Broglie
		De Broglie noted that relativity theory predicts that, when such a particle is set in motion, its total relativistic energy will increase, tending to infinity as the speed of light is approached.
		A consequence of de Broglie's reasoning is that a phase wave, often referred to as the "pilot" wave, appears to accompany the particle.
		Given de Broglie's assumptions, quantum mechanics, which is to say the study of the behavior and interpretation of the phase wave, is the study of an inherently relativistic phenomenon.

	De Broglie hypothesis - Wikipedia, the free encyclopedia
		The angular dependence of the reflected electron intensity was measured, and was determined to have the same diffraction pattern as those predicted by Bragg for X-Rays.
		Before the acceptance of the De Broglie hypothesis, diffraction was a property that was only exhibited by waves.
		When the De Broglie wavelength was inserted into the Bragg condition, the observed diffraction pattern was predicted, thereby experimentally confirming the De Broglie hypothesis.

	Louis, 7th duc de Broglie - Wikipedia, the free encyclopedia
		Louis-Victor-Pierre-Raymond, 7th duc de Broglie, generally known as Louis de Broglie (August 15, 1892–March 19, 1987), was a French physicist and Nobel Prize laureate.
		In his later career, Louis de Broglie worked to develop a causal explanation of wave mechanics, in opposition to the wholly probabilistic models which dominate quantum mechanical theory.
		Louis de Broglie became a member of the Académie des sciences in 1933, and was the academy's perpetual secretary from 1942.

		The fall of Napoleon restored peace, and de Broglie, returning to his diocese, was received amid the rejoicings of his clergy and flock.
		De Broglie with the Bishops of Namur and Tournai, and the Vicars-General of Mechlin and Liege took up the defence of the Catholic cause, and issued a pastoral instruction and, later on, a doctrinal judgment on the required oath to the Constitution.
		In 1819, de Broglie printed a protest concerning the state of religious affairs in Belgium, which was addressed to the Emperors of Austria and Russia and to the King of Prussia.

		De Broglie was best known for his particle-wave duality theory that matter has the properties of both particles and waves.
		De Broglie's theory of electron matter waves was later used by Schrödinger to develop wave mechanics.
		The central question in de Broglie's life was whether the statistical nature of atomic physics reflects an ignorance of the underlying theory or whether statistics is all that can be known.

	Planck, Einstein, and de Broglie
		Louis de Broglie proposed that Planck's energy-frequency relationship be extended to all kinds of particles.
		De Broglie's hypothesis was inspired by the fact that wave frequency and wavenumber are components of the same four-vector according to the theory of relativity, and are therefore closely related to each other.
		Planck, Einstein, and de Broglie had extensive backgrounds in classical mechanics, in which the concepts of energy, momentum, and mass have precise meaning.

		Louis-César-Victor-Maurice de Broglie, known as Maurice, was a distinguished physicist who made many contributions to the study of X-rays.
		This was the first observation of an absorption edge (de Broglie, 1913), though some further experiments were required to correctly interpret the absorption edges.
		Maurice thus set a precedent of scientific work in the de Broglie family, which was followed by his younger brother, Louis (born in 1892, seventeen years after Maurice).

	DE BROGLIE PARADOX
		It appears that De Broglie was attempting to give at least some structural answer to the question by saying that somehow mass should be viewed as a spatially localized circulating energy.
		(De Broglie - Bohm) The problem with these companion waves is that they are then seen to travel with a speed greater than c, so the "physical velocity" of the particle is then actually equated to the group velocity.
		As the electron energy is varied, there is an 8% dip in the forward scattering within a 0.5% bandwidth of a resonance energy of 80.874 MeV that corresponds to the de Broglie proper frequency as the frequency of atomic collisions.

	The Wave Nature of Matter
		At first, de Broglie had no idea what he meant by matter being waves, either; it was just a mathematical construct that unexpectedly turned out to be very helpful.
		What de Broglie did was to assume that any particle--an electron, an atom, a bowling ball, whatever--had a "wavelength" that was equal to Planck's constant divided by its momentum...
		According to de Broglie, the wavelength is equal to Planck's constant divided by the object's momentum; Planck's constant is very, very, very tiny, and the momentum of a bowling ball, relatively speaking, is huge.

		After the death of the mother, who died young, he was brought up by the Baroness Auguste de Staël, née Vernet; this aunt, although also a Protestant, exerted herself "to make a large-minded Christian of him in the Church to which she did not belong" (Monseigneur d'Hulst in "Le Correspondant", 25 May, 1895).

	The de Broglie Wavelength of a Packet of Light
		In his 1924 doctoral dissertation the French physicist Louis de Broglie suggested that a wavelength is associated with any particle, and it was found that on a quantum level particles like electrons do indeed exhibit wavelike phenomena such as interference and diffraction.
		Sebastião de Pádua and his colleagues at Federal University of Minas Gerais in Brazil were able to verify this prediction for the two-photon case (abiphoton) by performing a clever experiment that measures the interference effects of the wave packet after it was sent through a simple double slit.
		By preparing the two-photon light state in different ways, they were able to measure the de Broglie wavelength of the two-photon packet as a whole or of its constituent quanta.
