Institut D'optique Graduate School
The Institut d'optique Graduate School ("Institute of optics"), nicknamed SupOptique or IOGS, is one of the most prestigious French Grandes Ecoles and the leading French ''grande école'' in the field of Optics and its industrial and scientific applications, and a graduate school of the prestigious Paris-Saclay University and ParisTech. History Armand de Gramont, a rich industrialist and friend of Marcel Proust, was the man who had the idea to create the Institut d'Optique. In 1916, Gramont and Henri Chrétien (a French astronomer) were working together at the French Technical Aeronautics Section. Chrétien was working at the time on calculations for optical instruments. They both decided to create the project of building an institute dedicated to teaching Optics. That same year, Gramont became part of a committee that examined inventions that could interest the ministry of Defense. That is where he met Charles Fabry, who had previously become famous thanks to his experimental ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grande école
A ''grande école'' () is a specialised university that is separate from, but parallel and often connected to, the main framework of the French public university system. The grandes écoles offer teaching, research and professional training in single academic fields such as engineering, architecture, business administration, academic research, or public policy and administration. The schools only admit students through an extremely competitive examination process; a significant proportion of their graduates occupy senior positions in French business, academia, civil service and civil society. Grandes écoles primarily admit students based on their national ranking in competitive written and oral exams called ''concours,'' which are organised annually by the French central government. While anyone can register for ''concours'', successful candidates have almost always completed two or three years of dedicated preparatory classes (''classes preparatoires'') prior to admission. ...

Classe Préparatoire Aux Grandes écoles
The ''classes préparatoires aux grandes écoles'' (CPGE) (English: Higher School Preparatory Classes), commonly called ''classes prépas'' or ''prépas'', are part of the French post-secondary education system. They consist of two years of study (extendable to three or exceptionally four years) which act as an intensive preparatory course (or cram school) with the main goal of training students for enrolment in one of the ''grandes écoles''. The workload is one of the highest in Europe(29 to 45 contact hours a week, with up to 10 hours of guided tutorials and oral exam sessions). Unlike most students in France who enroll in public universities directly after receiving a high school diploma, students from CPGE have to take national competitive exams to be allowed to enroll in one of the ''grandes écoles''. These ''grandes écoles'' are higher education establishments (graduate schools) delivering master's degrees and rarely doctorates. They include science and engineering sch ...

Rubidium
Rubidium is the chemical element with the symbol Rb and atomic number 37. It is a very soft, whitish-grey solid in the alkali metal group, similar to potassium and caesium. Rubidium is the first alkali metal in the group to have a density higher than water. On Earth, natural rubidium comprises two isotopes: 72% is a stable isotope 85Rb, and 28% is slightly radioactive 87Rb, with a half-life of 48.8 billion years—more than three times as long as the estimated age of the universe. German chemists Robert Bunsen and Gustav Kirchhoff discovered rubidium in 1861 by the newly developed technique, flame spectroscopy. The name comes from the Latin word , meaning deep red, the color of its emission spectrum. Rubidium's compounds have various chemical and electronic applications. Rubidium metal is easily vaporized and has a convenient spectral absorption range, making it a frequent target for laser manipulation of atoms. Rubidium is not a known nutrient for any living organisms. However, r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helium
Helium (from el, ἥλιος, helios, lit=sun) is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling and melting point are the lowest among all the elements. It is the second lightest and second most abundant element in the observable universe (hydrogen is the lightest and most abundant). It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and in Jupiter, due to the very high nuclear binding energy (per nucleon) of helium-4, with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, the vast majority of which was formed during t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bose–Einstein Condensate
In condensed matter physics, a Bose–Einstein condensate (BEC) is a state of matter that is typically formed when a gas of bosons at very low densities is cooled to temperatures very close to absolute zero (−273.15 °C or −459.67 °F). Under such conditions, a large fraction of bosons occupy the lowest quantum state, at which point microscopic quantum mechanical phenomena, particularly wavefunction interference, become apparent macroscopically. A BEC is formed by cooling a gas of extremely low density (about 100,000 times less dense than normal air) to ultra-low temperatures. This state was first predicted, generally, in 1924–1925 by Albert Einstein following and crediting a pioneering paper by Satyendra Nath Bose on the new field now known as quantum statistics. In 1995, the Bose-Einstein condensate was created by Eric Cornell and Carl Wieman of the University of Colorado at Boulder using rubidium atoms; later that year, Wolfgang Ketterle of MIT produc ...

Strontium 88 MOT At IOGS
Strontium is the chemical element with the symbol Sr and atomic number 38. An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly chemically reactive. The metal forms a dark oxide layer when it is exposed to air. Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table, calcium and barium. It occurs naturally mainly in the minerals celestine and strontianite, and is mostly mined from these. Both strontium and strontianite are named after Strontian, a village in Scotland near which the mineral was discovered in 1790 by Adair Crawford and William Cruickshank; it was identified as a new element the next year from its crimson-red flame test color. Strontium was first isolated as a metal in 1808 by Humphry Davy using the then newly discovered process of electrolysis. During the 19th century, strontium was mostly used in the production of sugar from sugar beets (see strontian proc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
