A suggestion from Louis De Broglie, a physicist in France, showed us that these electrons are not point particles but waves.

* De Broglie – Bohm theory

A sodium atom traveling at about 30, 000 m / s would have a De Broglie wavelength of about 50 pico meters.

De Broglie deduced that if the duality equations already known for light were the same for any particle, then his hypothesis would hold.

For example, the electrons in a CRT display have a De Broglie wavelength of about 10 < sup >− 13 </ sup > m. To prevent the wave function for such a particle being spread over all space, de Broglie proposed using wave packets to represent particles that are localized in space.

De Broglie was awarded the Nobel Prize for Physics in 1929 for his hypothesis.

De Broglie himself had proposed a pilot wave construct to explain the observed wave – particle duality.

De Broglie had intended a career in humanities, and received his first degree in history.

De Broglie thus created a new field in physics, the mécanique ondulatoire, or wave mechanics, uniting the physics of energy ( wave ) and matter ( particle ).

De Broglie became a member of the Académie des sciences in 1933, and was the academy's perpetual secretary from 1942.

De Broglie was awarded a post as counselor to the French High Commission of Atomic Energy in 1945 for his efforts to bring industry and science closer together.

De Broglie – Bohm theory is based on the following:

In the formulation of the De Broglie – Bohm theory, there is only a wave function for the entire universe ( which always evolves by the Schrödinger equation ).

De Broglie – Bohm theory gives the same results as quantum mechanics.

De Broglie – Bohm theory is a theory that applies primarily to the whole universe.

De Broglie – Bohm theory deals with this by noting that spin is not a feature of the particle, but rather that of the wavefunction.

De Broglie – Bohm theory, from this perspective, chooses the position observable as a favored observable rather than, say, the momentum observable.

De Broglie – Bohm theory is often referred to as a " hidden variable " theory.

De Broglie – Bohm theory highlighted the issue of nonlocality: it inspired John Stewart Bell to prove his now-famous theorem, which in turn led to the Bell test experiments.

De Broglie – Bohm theory has been derived many times and in many ways.

De Broglie – Bohm theory has a history of different formulations and names.

The Schrödinger equation was developed principally from the De Broglie hypothesis, a wave equation that would describe particles, and can be constructed in the following way.

De Broglie relations: Einstein's light quanta hypothesis ( 1905 ) states that the energy E of a photon is proportional to the frequency ν ( or angular frequency, ω = 2πν ) of the corresponding quantum wavepacket of light:

Psychologists have been intrigued by De Palma's fascination with pathology, by the aberrant behavior aroused in characters who find themselves manipulated by others.

The Boulevard De La Madeleine, the Boulevard Malesherbes, and the Rue Royale ran to it with graceful flattery, bearing tidings of the Age of Reason.

Granted, the cosmological, philosophical, and cultural reverberations initiated by the De Revolutionibus were felt with increasing violence during the 300 years to follow.

The result was the `` Gross Report '', prepared by Gross, as chairman, with the assistance of two U.N. Under Secretaries, Constantin Stavropoulos and Philippe De Seynes.

Boniface was later to explain to the English that Robert of Burgundy and Guy De St.-Pol were easy enough to do business with ; ;

By 1913, Ferdinand Lot could begin an article subtitled `` La Conquete De La Grande-Bretagne par Les Saxons '' with the words, `` Il est difficile aujourd'hui d'entretenir des illusions sur la valeur du recit traditionnel de la conquete de la Grande-Bretagne.

`` There's a big boat anchored near the Place De La Concorde, with a swimming pool in it -- didn't you notice it??

Alex's instruction was rapid, for the doctor had to go off to the Rue Ecole De Medecine to hear more speeches with only time for one sip of wine to sustain him through them all.

We have recently entered into an agreement with Compagnie Generale De Telegraphie Sans Fil ( CSF ) of France for the exclusive exchange of technical information on thermoelectric materials.

This happy, always smiling lad with the sunny disposition is our new Junior Mr. Canada -- Henri De Courcy.

So with four complete Push-Pull Super-Sets No. 1, four of No. 2, four of No. 3 and four to six sets of the Incline Bench Press, you can see that Henri De Courcy has had a terrific mass-building, muscle-shaping, torso-defining workout that cannot be improved upon.

And it is thought by many who think about such things that Quasimodo is the logical culmination of a school that started with Monet, progressed through Kandinsky and the cubist Picasso, and blossomed just recently in Pollock and De Kooning.

A Bureau De La Demographie ( A. Romaniuk, Director ) was formed under AIMO in the Congo, to work in close rapport with the Section Statistique of the Secretariat General.

A member of the IRSAC staff ( E. Van De Walle ) was recently delegated to cooperate with AIMO in the development of demographic statistics in this territory.

As usual, he made no attempt to get in touch with Carmine G. De Sapio, the Manhattan leader.

Diario De La Marina was the oldest and most influential paper in Cuba, with a reputation for speaking out against tyranny.

It was won by Georges Bouton of the De Dion-Bouton Company, in a car he had constructed with Albert, the Comte de Dion, but as he was the only competitor to show up it is rather difficult to call it a race.

" is attributed to his son William De Morgan, but a family friend John Thomas Graves was prolific, and a manuscript with over 2, 800 has been preserved.

The proper form of the name is evidently Abrasax, as with the Greek writers, Hippolytus, Epiphanias, Didymus ( De Trin.

Several of Alexander's works were published in the Aldine edition of Aristotle, Venice, 1495 – 1498 ; his De Fato and De Anima were printed along with the works of Themistius at Venice ( 1534 ); the former work, which has been translated into Latin by Grotius and also by Schulthess, was edited by J. C. Orelli, Zürich, 1824 ; and his commentaries on the Metaphysica by H. Bonitz, Berlin, 1847.
