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 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:

De Broglie – Bohm theory tries to solve the measurement problem very differently: this interpretation contains not only the wavefunction, but also the information about the position of the particle ( s ).

Bohm developed Pilot Wave Theory into what is now called the De Broglie-Bohm theory.

In fact, the first two thirds of De Veritate are devoted to an exposition of Herbert's theory of knowledge.

* 1684 – Isaac Newton's derivation of Kepler's laws from his theory of gravity, contained in the paper De motu corporum in gyrum, is read to the Royal Society by Edmund Halley.

His anatomical reports, based mainly on dissection of monkeys and pigs, remained uncontested until 1543, when printed descriptions and illustrations of human dissections were published in the seminal work De humani corporis fabrica by Andreas Vesalius where Galen's physiological theory was accommodated to these new observations.

Galen's theory of the physiology of the circulatory system endured until 1628, when William Harvey published his treatise entitled De motu cordis, in which he established that blood circulates, with the heart acting as a pump.

Enumerative graph theory then rose from the results of Cayley and the fundamental results published by Pólya between 1935 and 1937 and the generalization of these by De Bruijn in 1959.

As a physical basis, Kepler drew by analogy on William Gilbert's theory of the magnetic soul of the Earth from De Magnete ( 1600 ) and on his own work on optics.

In his treatise De pictura ( 1435 ) he explains the theory, of the accumulation of people, animals, and buildings, which create harmony amongst each other, and " hold the eye of the learned and unlearned spectator for a long while with a certain sense of pleasure and emotion ".

According to De Leonist theory, militant industrial unions ( specialized trade unions ) are the vehicle of class struggle.

Augustus De Morgan and George Boole improved the exposition of the theory.

His works include the early and very influential De Inventione ( On Invention, often read alongside the Ad Herennium as the two basic texts of rhetorical theory throughout the Middle Ages and into the Renaissance ), De Oratore ( a fuller statement of rhetorical principles in dialogue form ), Topics ( a rhetorical treatment of common topics, highly influential through the Renaissance ), Brutus ( Cicero ) ( a discussion of famous orators ) and Orator ( a defense of Cicero's style ).

Brazzaville hereby became the capital of the so-called Free French in Africa, ruled in theory by a Conseil de défense de l ' Empire set up by De Gaulle on 27 October 1940.

* Critics of sedevacantism argue that this also means that the theory advanced by the seventeenth-century theologian and Doctor of the Church Robert Bellarmine that a pope who fell into heresy would automatically forfeit his office and could be formally deposed has been overruled by Church authority by Benedict XIV in " De Synodo Dioecesano " ( 10, 1, 5 ) and by the 1917 Code of Canon Law, Can.

The original use of the term was as a form of praxis rather than theory – a term used as a convention to refer to something that otherwise cannot be discussed in words – and early writings such as the Dao De Jing and the I Ching make pains to distinguish between conceptions of Dao ( sometimes referred to as " named Dao ") and the Dao itself ( the " unnamed Dao "), which cannot be expressed or understood in language.

* Christiaan Huygens writes the first book to be published on probability theory, De ratiociniis in ludo aleae (" On Reasoning in Games of Chance ").

In relation to this discrepancy in the frequency of Lucretius ' reference to the apparent subject of his poem, Kannengiesse advances the theory that Lucretius wrote the first version of De rerum natura for the reader at large, and subsequently revised in order to write it for Memmius.

" According to De Forest, it was thanks to Gibbs that he realized early on " that the leaders in electrical development would be those who pursued the higher theory of waves and oscillations and the transmission by these means of intelligence and power.

De Stijl was also linked by Gino Severini to Cubist theory through the writings of Albert Gleizes.

Boole's initial involvement in logic was prompted by a current debate on quantification, between Sir William Hamilton who supported the theory of " quantification of the predicate ", and Boole's supporter Augustus De Morgan who advanced a version of De Morgan duality, as it is now called.

* December 10 – Isaac Newton's derivation of Kepler's laws from his theory of gravity, contained in the paper De motu corporum in gyrum, is read to the Royal Society by Edmund Halley.

After Blaise Pascal encouraged him to do so, Huygens wrote the first book on probability theory, De ratiociniis in ludo aleae (" On Reasoning in Games of Chance "), which he had published at 5: 56 pm on April 10, 1657.

In the theological field he produced his Chrysopassus ( Augsburg, 1514 ), in which he developed a Semi-Pelagian theory of predestination, while he obtained some fame as commentator on the Summulae of Peter of Spain and on Aristotle's De caelo and De anima.
