André-Marie Ampère was a French physicist and mathematician who was one of the founders of the science of classical electromagnetism, which he referred to as "electrodynamics". He is also the inventor of numerous applications, such as the solenoid and the electrical telegraph. As an autodidact, Ampère was a member of the French Academy of Sciences and professor at the École polytechnique and the Collège de France.
Wave–particle duality is the concept in quantum mechanics that quantum entities exhibit particle or wave properties according to the experimental circumstances. It expresses the inability of the classical concepts such as particle or wave to fully describe the behavior of quantum objects. During the 19th and early 20th centuries, light was found to behave as a wave, and then later discovered to have a particulate character, whereas electrons were found to act as particles, and then later discovered to have wavelike aspects. The concept of duality arose to name these contradictions.
Jules Henri Poincaré was a French mathematician, theoretical physicist, engineer, and philosopher of science. He is often described as a polymath, and in mathematics as "The Last Universalist", since he excelled in all fields of the discipline as it existed during his lifetime. Due to his scientific success, influence and his discoveries, he has been deemed the "the philosopher par excellence of modern science."
Adrien-Marie Legendre was a French mathematician who made numerous contributions to mathematics. Well-known and important concepts such as the Legendre polynomials and Legendre transformation are named after him. He is also known for his contributions to the method of least squares, and was the first to officially publish on it, though Carl Friedrich Gauss had discovered it before him.
Louis Victor Pierre Raymond, 7th Duc de Broglie was a French physicist and aristocrat who made groundbreaking contributions to quantum theory. In his 1924 PhD thesis, he postulated the wave nature of electrons and suggested that all matter has wave properties. This concept is known as the de Broglie hypothesis, an example of wave–particle duality, and forms a central part of the theory of quantum mechanics.
Charles-Augustin de Coulomb was a French officer, engineer, and physicist. He is best known as the eponymous discoverer of what is now called Coulomb's law, the description of the electrostatic force of attraction and repulsion. He also did important work on friction.
Laurent-Moïse Schwartz was a French mathematician. He pioneered the theory of distributions, which gives a well-defined meaning to objects such as the Dirac delta function. He was awarded the Fields Medal in 1950 for his work on the theory of distributions. For several years he taught at the École polytechnique.
Élie Joseph Cartan was an influential French mathematician who did fundamental work in the theory of Lie groups, differential systems, and differential geometry. He also made significant contributions to general relativity and indirectly to quantum mechanics. He is widely regarded as one of the greatest mathematicians of the twentieth century.
Pierre Maurice Marie Duhem was a French theoretical physicist who worked on thermodynamics, hydrodynamics, and the theory of elasticity. Duhem was also a historian of science, noted for his work on the European Middle Ages, which is regarded as having created the field of the history of medieval science. As a philosopher of science, he is remembered principally for his views on the indeterminacy of experimental criteria.
Jean-Pierre Vigier was a French theoretical physicist, known for his work on the foundations of physics, in particular on his stochastic interpretation of quantum physics.
Rudolf Friedrich Alfred Clebsch was a German mathematician who made important contributions to algebraic geometry and invariant theory. He attended the University of Königsberg and was habilitated at Berlin. He subsequently taught in Berlin and Karlsruhe. His collaboration with Paul Gordan in Giessen led to the introduction of Clebsch–Gordan coefficients for spherical harmonics, which are now widely used in quantum mechanics.
Léon Nicolas Brillouin was a French physicist. He made contributions to quantum mechanics, radio wave propagation in the atmosphere, solid-state physics, and information theory.
Bernard d'Espagnat was a French theoretical physicist, philosopher of science, and author, best known for his work on the nature of reality. Wigner-d'Espagnat inequality is partially named after him.
Jean Cavaillès was a French philosopher and logician who specialized in philosophy of mathematics and philosophy of science. He took part in the French Resistance within the Libération movement and was arrested by the Gestapo on 17 February 1944 and shot on 4 April 1944.
The International League of Antiquarian Booksellers is a non-profit umbrella organization of bookseller associations, with its legal location in Geneva, Switzerland. It federates 22 National Associations of Antiquarian Booksellers, representing nearly 2000 dealers in 32 countries. Antiquarian booksellers affiliated to the League adhere to the ILAB Code of Ethics, and the League aims to server as a global network for the rare book trade.
Michel Bitbol is a French researcher in philosophy of science.
In physics, a quantum is the minimum amount of any physical entity involved in an interaction.
Andreas Jaszlinszky was the Slovak-born author of the early physics textbooks Institutiones physicae pars prima, seu physica generalis and Institutiones physicae pars altera, seu physica particularis.
Jacques Solomon was a French physicist and Marxist who played a central role in the debate over quantum mechanics in France in the 1930s and 1940s. He was killed by firing squad at Fort Mont-Valérien in 1942.
