Ali Javan
Ali Javan ( fa, علی جوان, Ali Javān; December 26, 1926 – September 12, 2016) was an Iranian-American physicist and inventor. He was the first to propose the concept of the gas laser in 1959 at the Bell Telephone Laboratories. A successful prototype, constructed by him in collaboration with William R. Bennett, Jr., W. R. Bennett, Jr., and Donald R. Herriott, D. R. Herriott was demonstrated in 1960. His other contributions to science have been in the fields of quantum physics and spectroscopy. Life and career Ali Javan was born in Tehran to Iranian Azerbaijanis, Iranian Azerbaijani parents originally from Tabriz. He attended a school conducted by Zoroastrians.''Smithsonian (magazine), Smithsonian April 1971 (Volume 2, Number 1)'', ''Ali Javan and his 40 lasers'', Francis E. Wylie He graduated from Alborz High School, and started his university studies at the School of Science at the University of Tehran for a year.

Iranian-American
Iranian Americans are United States citizens or nationals who are of Iranian ancestry or who hold Iranian citizenship. Iranian Americans are among the most highly educated people in the United States. They have historically excelled in business, academia, science, the arts, and entertainment. Most Iranian Americans arrived in the United States after 1979, as a result of the Iranian Revolution and the fall of the Persian monarchy, with over 40% settling in California, specifically Los Angeles. Unable to return to Iran, they have created many distinct ethnic enclaves, such as the Los Angeles Tehrangeles community. The Iranian American community has become successful, with many becoming doctors, engineers, lawyers, and tech entrepreneurs. Based on a 2012 announcement by the National Organization for Civil Registration, an organization of the Ministry of Interior of Iran, the United States has the highest number of Iranians outside the country. In 2021 the Ministry of Fore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles H
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed i ...

Alborz High School
Mandegar Alborz High School ( fa, دبیرستان ماندگار البرز) is a college-preparatory high school located in the heart of Tehran, Iran. It is one of the first modern high schools in Asia and the Middle East, named after the Alborz mountain range, north of Tehran. Its place in the shaping of Iran's intellectual elite compares with that of Eton College in England and institutions such as Phillips Academy, Phillips Exeter Academy, and Milton Academy in the United States. History The school was founded as an elementary school in 1873 by a group of American Presbyterian missionaries led by James Bassett. This was in the 26th year of the reign of Nasereddin Shah Qajar, 22 years after Amir Kabir founded the Dar ul-Funun school in Tehran, and 33 years before the Constitutional Revolution in Persia (as it was known back then; later it became "Iran" during the Reza Shah Era). When Dr. Samuel Jordan arrived in Persia in 1898, he instituted change; subsequently, Alborz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smithsonian (magazine)
''Smithsonian'' is the official journal published by the Smithsonian Institution in Washington, D.C. The first issue was published in 1970. History The history of ''Smithsonian'' began when Edward K. Thompson, the retired editor of ''Life'' magazine, was asked by the then-Secretary of the Smithsonian, S. Dillon Ripley, to produce a magazine "about things in which the Smithsonian nstitutionis interested, might be interested or ought to be interested." Thompson would later recall that his philosophy for the new magazine was that it "would stir curiosity in already receptive minds. It would deal with history as it is relevant to the present. It would present art, since true art is never dated, in the richest possible reproduction. It would peer into the future via coverage of social progress and of science and technology. Technical matters would be digested and made intelligible by skilled writers who would stimulate readers to reach upward while not turning them off with jargon ...

Tabriz
Tabriz ( fa, تبریز ; ) is a city in northwestern Iran, serving as the capital of East Azerbaijan Province. It is the sixth-most-populous city in Iran. In the Quru River valley in Iran's historic Azerbaijan region between long ridges of volcanic cones in the Sahand and Eynali mountains, Tabriz's elevation ranges between above sea level. The valley opens up into a plain that gently slopes down to the eastern shores of Lake Urmia, to the west. With cold winters and temperate summers, Tabriz is considered a summer resort. It was named World Carpet Weaving City by the World Crafts Council in October 2015 and Exemplary Tourist City of 2018 by the Organisation of Islamic Cooperation. With a population of over 1.7 million (2016), Tabriz is the largest economic hub and metropolitan area in northwest Iran. The population is bilingual, speaking Azerbaijani and Persian.

Spectroscopy
Spectroscopy is the field of study that measures and interprets the electromagnetic spectra that result from the interaction between electromagnetic radiation and matter as a function of the wavelength or frequency of the radiation. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory (LIGO) In simpler terms, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum. Historically, spectroscopy originated as the study of the wavelength dependence of the absorption by gas phase matter of visible light dispersed by a prism. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structure an ...

Quantum Physics
Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics, the collection of theories that existed before the advent of quantum mechanics, describes many aspects of nature at an ordinary ( macroscopic) scale, but is not sufficient for describing them at small (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic) scale. Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a bound system are restricted to discrete values ( quantization); objects have characteristics of both particles and waves (wave–particle duality); and there are limit ...

Donald R
Donald is a masculine given name derived from the Gaelic name ''Dòmhnall''.. This comes from the Proto-Celtic *''Dumno-ualos'' ("world-ruler" or "world-wielder"). The final -''d'' in ''Donald'' is partly derived from a misinterpretation of the Gaelic pronunciation by English speakers, and partly associated with the spelling of similar-sounding Germanic names, such as '' Ronald''. A short form of ''Donald'' is '' Don''. Pet forms of ''Donald'' include ''Donnie'' and ''Donny''. The feminine given name ''Donella'' is derived from ''Donald''. ''Donald'' has cognates in other Celtic languages: Modern Irish ''Dónal'' (anglicised as ''Donal'' and ''Donall'');. Scottish Gaelic ''Dòmhnall'', ''Domhnull'' and ''Dòmhnull''; Welsh '' Dyfnwal'' and Cumbric ''Dumnagual''. Although the feminine given name '' Donna'' is sometimes used as a feminine form of ''Donald'', the names are not etymologically related.
