Jean Brossel
Jean Brossel (15 August 1918 – 4 February 2003) was a French physicist known for his work on quantum optics. He was born and died in Périgueux. Brossel passed the entrance exam for l'École normale supérieure (ENS) 1938, but then was for two years a soldier. From 1941 to 1945 he studied at the ENS under Alfred Kastler and then went to the group of Samuel Tolansky in Manchester where he spent the years 1945–1948 before moving in 1948 to Francis Bitter at Massachusetts Institute of Technology, MIT. In 1951 for work done at MIT, Brossel received his PhD in Paris under Kastler with a thesis on the application of double resonance methods (developed by Kastler and him) to the study of the excited states of Mercury (element), Hg. After completing his PhD, Brossel was attaché des recherches and then Maître de Recherches at Centre national de la recherche scientifique, CNRS. In 1955 he became a professor at the Faculté des Sciences in Paris (and later a professor at the Universi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portrait De Jea0 -Brossel
A portrait is a portrait painting, painting, portrait photography, photograph, sculpture, or other artistic representation of a person, in which the face is always predominant. In arts, a portrait may be represented as half body and even full body. If the subject in full body better represents personality and mood, this type of presentation may be chosen. The intent is to display the likeness, Personality type, personality, and even the mood of the person. For this reason, in photography a portrait is generally not a Snapshot (photography), snapshot, but a composed image of a person in a still position. A portrait often shows a person looking directly at the painter or photographer, to most successfully engage the subject with the viewer, but portrait may be represented as a profile (from aside) and 3/4. History Prehistorical portraiture Plastered human skulls were reconstructed human skulls that were made in the ancient Levant between 9000 and 6000 BC in the Pre-Pottery Ne ...

1918 Births
The ceasefire that effectively ended the First World War took place on the eleventh hour of the eleventh day of the eleventh month of this year. Also in this year, the Spanish flu pandemic killed 50–100 million people worldwide. In Russia, this year runs with only 352 days. As the result of Julian to Gregorian calendar switch, 13 days needed to be skipped. Wednesday, January 31 ''(Julian Calendar)'' was immediately followed by Thursday, February 14 ''(Gregorian Calendar)''.

People From Périgueux
The term "the people" refers to the public or Common people, common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of Person, persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Declaration on the Rights of Indigenous Peoples, Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independence, independent sovereignty and therefore secession.

Prix Ampère
Prix was an American power pop band formed in Memphis, Tennessee, in 1975 by Tommy Hoehn and Jon Tiven. The group ended up primarily as a studio project. Its recordings were produced by Tiven along with former Big Star member Chris Bell, who also played guitar and sang backup vocals. Prix is also famous for its use of banjo. Alex Chilton also participated in the recordings, along with session drummer Hilly Michaels. Although the group generated some major record label interest—notably from Mercury Records and Columbia/CBS Records—it ultimately only released a double A-side single on Ork Records in 1977 and a single on Miracle Records in 1978. Its only live performance came at a CBS Records showcase in 1976. In 1977, just as Ork Records released the first single and booked the group at CBGB, Prix broke up due both to Hoehn's unwillingness to remain in New York and to creative differences. In 1978, two of the songs recorded during the Prix sessions were included on ''Losing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Académie Des Sciences
The French Academy of 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 method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the academy), it is one of the five Academies of the . __TOC__ 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 nationale de France, Bibliothèque Nationale, 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 ins ...

Holweck Prize
The Fernand Holweck Medal and Prize is a major European prize for Physics awarded jointly every year by the British Institute of Physics (IOP) and the Société Française de Physique (SFP). It is one of the four Grand Prix of the SFP and one of the four International Bilateral Awards of the IOP, consisting of a gold medal and a 3000€ cash prize. History The prize was established in 1945 as a memorial to Fernand Holweck and other French physicists who were persecuted or killed by the Nazis during the German occupation of France during World War II, from 1940 to 1945. It was originally a £150 prize. It is awarded for distinguished work in experimental physics (which reflects Holweck's scientific interest) or in theoretical physics which is closely related to experimentation. The Holweck Prize is awarded every year, alternately to a French physicist and a British or Irish physicist. In 1974 two awards were made to mark the centenaries of the two societies.

Optical Pumping
Optical pumping is a process in which light is used to raise (or "pump") electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction to pump the active laser medium so as to achieve population inversion. The technique was developed by the 1966 Nobel Prize winner Alfred Kastler in the early 1950s. Page 56. Optical pumping is also used to cyclically pump electrons bound within an atom or molecule to a well-defined quantum state. For the simplest case of coherent two-level optical pumping of an atomic species containing a single outer-shell electron, this means that the electron is coherently pumped to a single hyperfine sublevel (labeled m_F\!), which is defined by the polarization of the pump laser along with the quantum selection rules. Upon optical pumping, the atom is said to be ''oriented'' in a specific m_F\! sublevel, however, due to the cyclic nature of optical pumping, the bound electron will actually be unde ...

Périgueux
Périgueux (, ; or ) is a commune in the Dordogne department, in the administrative region of Nouvelle-Aquitaine, southwestern France. Périgueux is the prefecture of Dordogne, and the capital city of Périgord. It is also the seat of a Roman Catholic diocese. History The name ''Périgueux'' comes from Petrocorii, a Latinization of Celtic words meaning "the four tribes" – the Gallic people that held the area before the Roman conquest. Périgueux was their capital city. In 200 BC, the Petrocorii came from the north and settled at Périgueux and established an encampment at La Boissière. After the Roman invasion, they left this post and established themselves on the plain of L'Isle, and the town of Vesunna was created. This Roman city was eventually embellished with amenities such as temples, baths, amphitheatres, and a forum. At the end of the third century AD, the Roman city was surrounded by ramparts, and the town took the name of Civitas Petrocoriorum. In the ...
