Kastler–Brossel Laboratory
The Kastler–Brossel Laboratory, (formerly the Laboratory of Hertzian Spectroscopy) located in Paris, France, is a research laboratory specializing in fundamental physics of quantum systems. Founded in 1951 by Alfred Kastler and Jean Brossel, it is a joint research unit (French UMR 8552) operated by the French National Centre for Scientific Research (CNRS), the École normale supérieure, the Sorbonne University and the Collège de France. Brief history The laboratory was founded in 1951 by Alfred Kastler (Nobel Prize in Physics in 1966) and Jean Brossel on the theme of the interaction between light and matter. The initial name of laboratory was the « Laboratoire de spectroscopie Hertzienne de l'ENS » (Laboratory of Hertzian Spectroscopy). It is located in the Department of Physics of École normale supérieure. In 1967, a second site opened on the Jussieu campus. In 1994, the laboratory changed its name to « Laboratoire Kastler Brossel » in honor of its two founders. Now ...

Fundamental Physics
In physics, the fundamental interactions, also known as fundamental forces, are the interactions that do not appear to be reducible to more basic interactions. There are four fundamental interactions known to exist: the gravity, gravitational and electromagnetism, electromagnetic interactions, which produce significant long-range forces whose effects can be seen directly in everyday life, and the strong interaction, strong and weak interactions, which produce forces at subatomic scale, minuscule, subatomic distances and govern nuclear interactions. Some scientists hypothesize that a fifth force might exist, but these hypotheses remain speculative. Each of the known fundamental interactions can be described mathematically as a ''field (physics), field''. The gravitational force is attributed to the curvature of spacetime, described by Albert Einstein, Einstein's general theory of relativity. The other three are discrete quantum field theory, quantum fields, and their interactions ...

Research Institutes In France
Research is "creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economic ...

Physics Laboratories
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. ...

Christophe Salomon
Christophe Salomon (born in 1953) is a French physicist. Specialist in quantum optics and cold atoms, Christophe Salomon is interested in the superfluidity of quantum gases and in the measurement of time using atomic clocks. A pioneer in this disciplinary field, he has helped to give France a world leadership position in the field. Biography From 1973 to 1976, he was a student at the École centrale des arts et manufactures in Paris. He then defended his postgraduate thesis in 1979. He joined the CNRS in 1980 as a research fellow at the Laser Physics Laboratory, University of Paris-Nord. In 1984, he completed a thesis in high-resolution laser spectroscopy and then embarked on a post-doctoral fellowship at JILA, University of Colorado (USA). Fascinated by the first work in the United States on the manipulation of objects and atoms by laser, Christophe Salomon was introduced to these new techniques at the University of Colorado, before joining the first research group in France o ...

French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal, since no statutes had as yet been laid down for the institution. In contrast to its Brit ...
