Maurice Lévy (physicist)
Maurice Marc Lévy (7 September 1922 – 13 April 2022) was a French physicist and teacher. He was president of the CNES from 1973 to 1976. Education Maurice Lévy obtained his Baccalauréat at the Lycée Bugeaud in Algiers, and then graduated in mathematics and physics from the University of Algiers. He then obtained a graduate degree in optics and entered the CNRS in 1945. He left Algeria for France and joined the Physical Research Laboratory of the Sorbonne ( LRPS), directed by Jean Cabannes. After a brief stay at the University of Leiden, he defended his thesis in 1949 under the supervision of Jean Cabannes. Louis de Broglie participated in his thesis examination. Career In 1949, he visited the University of Manchester to work under the direction of Léon Rosenfeld. In 1950, he joined the Institute for Advanced Study in Princeton, directed by J. Robert Oppenheimer. He returned to France in 1952, became senior researcher at the CNRS and worked in the physics departme ...

CNES
The (CNES; French: ''Centre national d'études spatiales'') is the French government space agency (administratively, a "public administration with industrial and commercial purpose"). Its headquarters are located in central Paris and it is under the supervision of the French Ministries of Defence and Research. It operates from the Toulouse Space Centre and the Guiana Space Centre, but also has payloads launched from space centres operated by other countries. The president of CNES is Philippe Baptiste. CNES is a member of Institute of Space, its Applications and Technologies. It is Europe's largest and most important national organization of its type. History CNES was established under President Charles de Gaulle in 1961. It is the world's third oldest space agency, after the Soviet space program (Russia), and NASA (United States). CNES was responsible for the training of French astronauts, until the last active CNES astronauts transferred to the European Space Agency ...

Léon Rosenfeld
Léon Rosenfeld (; 14 August 1904 in Charleroi – 23 March 1974) was a Belgian physicist and Marxist. Rosenfeld was born into a secular Jewish family. He was a polyglot who knew eight or nine languages and was fluent in at least five of them. Rosenfeld obtained a PhD at the University of Liège in 1926, and he was a close collaborator of the physicist Niels Bohr. He did early work in quantum electrodynamics that predates by two decades the work by Paul Dirac and Peter Bergmann. Rosenfeld contributed to a wide range of physics fields, from statistical physics and quantum field theory to astrophysics. Along with Frederik Belinfante, he derived the Belinfante–Rosenfeld stress–energy tensor. He also founded the journal ''Nuclear Physics'' and coined the term lepton. In 1933, Rosenfeld married Yvonne Cambresier, who was one of the first women to obtain a Physics PhD from a European university. They had a daughter, Andrée Rosenfeld (1934–2008) and a son, Jean Rosenfeld. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
