Maurice Lévy (physicist)
Maurice Marc Lévy (7 September 1922 – 13 April 2022) was a French theoretical physicist known for his work on the Sigma model in particle physics. He was president of the CNES from 1973 to 1976. Education Lévy was born in Tlemcen of the French Algeria. He 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, Lévy visited the University of Manchester to work under the direction of Léon Rosenfeld. In 1950, he joined the Institute for Advanced Study in Princeton, New Jersey, Princeton, directed by J. Robert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Space Agency
CNES () is the French national space agency. Headquartered in central Paris, the agency is overseen by the ministries of the Armed Forces, Economy and Finance and Higher Education, Research and Innovation. It operates from the Toulouse Space Centre and the Guiana Space Centre. The president of CNES is Philippe Baptiste. CNES is a member of Institute of Space, its Applications and Technologies. It is Europe's largest 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 in 2001. , CNES is working with Germany and a few other governments to start a modest research effort with the hope to propose a LOX/methane reusable launch vehicle by mid-2015. If built, flight testing wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chiral Symmetry Breaking
In particle physics, chiral symmetry breaking generally refers to the dynamical spontaneous breaking of a chiral symmetry associated with massless fermions. This is usually associated with a gauge theory such as quantum chromodynamics, the quantum field theory of the strong interaction, and it also occurs through the Brout-Englert-Higgs mechanism in the electroweak interactions of the standard model. This phenomenon is analogous to magnetization and superconductivity in condensed matter physics - where, for example, chiral symmetry breaking is the mechanism by which disordered 3D magnetic systems have a finite transition temperature. The basic idea was introduced to particle physics by Yoichiro Nambu, in particular, in the Nambu–Jona-Lasinio model, which is a solvable theory of composite bosons that exhibits dynamical spontaneous chiral symmetry when a 4-fermion coupling constant becomes sufficiently large. Nambu was awarded the 2008 Nobel prize in physics "for the discovery o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Il Nuovo Cimento
''Nuovo Cimento'' is a series of peer-reviewed scientific journals of physics. The series was first established in 1855, when Carlo Matteucci and Raffaele Piria started publishing ''Il Nuovo Cimento'' as the continuation of ''Il Cimento'', which they established in 1844. In 1897, it became the official journal of the Italian Physical Society. Over time, the journal split into several sub-journals: * ''Nuovo Cimento A'' (1965–1999): Focused on particle physics. The journal ended when it was merged into the ''European Physical Journal'', in 1999. * ''Nuovo Cimento B'' (1965–2010): Focused on relativity, astronomy, and mathematical physics. As of 1 January 2011 it continues publication as the '' European Physical Journal Plus''. * ''Nuovo Cimento C'' (1978–present): Focuses on geophysics, astrophysics, and biophysics. * ''Nuovo Cimento D'' (1982–1998): Focuses on solid state physics, atomic physics, and molecular biology. The journal ended when it was merged into the ''Euro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Murray Gell-Mann
Murray Gell-Mann (; September 15, 1929 – May 24, 2019) was an American theoretical physicist who played a preeminent role in the development of the theory of elementary particles. Gell-Mann introduced the concept of quarks as the fundamental building blocks of the strongly interacting particles, and the renormalization group as a foundational element of quantum field theory and statistical mechanics. He played key roles in developing the concept of chirality in the theory of the weak interactions and spontaneous chiral symmetry breaking in the strong interactions, which controls the physics of the light mesons. In the 1970s he was a co-inventor of quantum chromodynamics (QCD) which explains the confinement of quarks in mesons and baryons and forms a large part of the Standard Model of elementary particles and forces. Murray Gell-Mann received the 1969 Nobel Prize in Physics for his work on the theory of elementary particles. Life and education Gell-Mann was bo ...

John Iliopoulos
John (Jean) Iliopoulos (Greek language, Greek: Ιωάννης Ηλιόπουλος; 1940) is a Greeks, Greek physicist. He is the first person to present the Standard Model of particle physics in a single report. He is best known for his prediction of the charm quark with Sheldon Glashow and Luciano Maiani (the "Standard Model (mathematical formulation)#The GIM mechanism and the CKM matrix, GIM mechanism"). Iliopoulos is also known for demonstrating the cancellation of Anomaly (physics), anomalies in the Standard model. He is further known for the Fayet–Iliopoulos D-term formula, which was introduced in 1974. He is currently an honorary member of Laboratory of theoretical physics of École Normale Supérieure, École normale supérieure, Paris.

Cargèse
Cargèse (; or ; ; ) is a village and '' commune'' in the Corse-du-Sud department of France on the west coast of the island of Corsica, 27 km north of Ajaccio. , the commune had a population of 1,325. The village was established at the end of the 18th century by the descendants of a group of immigrants from the Mani Peninsula of the Greek Peloponnese who had first settled in Corsica a hundred years earlier. The economy of the village is now based around tourism. Cargèse is noted for having two 19th-century churches that face one another across a small valley overlooking the harbour and the sea. One was built by the descendants of the Greek immigrants and the other by native Corsicans. History Paomia 1676 to 1731 In the second half of the 17th century there was a substantial emigration from the Mani Peninsula of the Greek Peloponnese. This was mainly driven by the wish to escape from the control of the Ottoman Turks but was also prompted by the lack of arable land and ...

Yves Rocard
Yves-André Rocard (; 22 May 1903 – 16 March 1992) was a French physicist who helped develop the atomic bomb for France. Lifes Rocard was born in Vannes. After obtaining a double doctorate in mathematics (1927) and physics (1928) he was awarded a professorship in electronic physics at the École normale supérieure in Paris. As a member of a Resistance group during the Second World War he flew to the UK in a small plane as part of a dangerous mission and was able to provide British intelligence with invaluable information. There he met up with Charles de Gaulle who named him Director of Research in the Forces navales françaises libres (the Navy of Free France). He became particularly interested in the detection of solar radio emissions by British Radar, which were causing military problems by jamming detection during periods of high emission, and was able to create a new radio navigational beam station. As research director, Rocard followed the French troops entering Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Institute For Advanced Study
The Institute for Advanced Study (IAS) is an independent center for theoretical research and intellectual inquiry located in Princeton, New Jersey. It has served as the academic home of internationally preeminent scholars, including Albert Einstein, J. Robert Oppenheimer, Emmy Noether, Hermann Weyl, John von Neumann, Michael Walzer, Clifford Geertz and Kurt Gödel, many of whom had emigrated from Europe to the United States.
