Pair of letters written and signed by Louis de Broglie, University of Paris, 1952-53.

Specifications: Each letter is [4] pages long, on the letterhead of the University of Paris. 21x13 cm. The letter was written and signed by Prof. Louis de Broglie. French.

De Broglie's letters testify to the close cooperation between theoretical physicists in the development of the quantum theory.

* The letter from 1952 presents physics formulas that connect various theories and explain their relationship. He explains the wave function as something probabilistic and explains its relationship with physical reality, as shown by the measurements of the waves.
Later on, he discusses the theories of Vigia and Albert Einstein regarding the movement of particles and discusses the significance of chemical movement of the atoms at the edges of material. He grapples with Einstein's questions on Bohm's theories and comments that he intends on publishing a book with notes that he wrote together with Vigia between 1924-1927. At the end of the letter, he asks Bohm about his work and expresses his hope that Vigia's transfer to Brazil will promote his research.

* In the letter written in 1953, De Broglie writes about his efforts to secure funding for research by Vigia, who had returned from Brazil.

He continues grappling with Einstein's claims and the explanations he gave for Bohm's theories. De Broglie notes that the quantum theory is very subjective, and explains what he means.
He then discusses the influence of Jung's theory on his outlook on physics and how they helped him understand wave mechanics, which he developed in 1923-1926.
He concludes by noting Bohm's impending visit to France and notes that he hopes to take advantage of the time for research studies.

Background: Louis-Victor-Pierre-Raymond, 7e duc de Broglie (1892-1987) was a French physicist who studied and taught in the University of Paris. In 1929, he won the Nobel Prize for his study regarding the wave nature of electrons. His studies regarding electromagnetic radiation and his work on the de Broglie–Bohm theory strongly promoted the theory of quantum mechanics.

Condition: Very fine. Minimal aging stains.
