Nikolai Borisovich Delone
Nikolai Delaunay, Jr. (aka Delone, Nikolai Borisovich; 22 May 1926 – 11 September 2008) was a Soviet physicist born in Leningrad, USSR (now Saint Petersburg, Russia). Life Delone was born in Leningrad on 22 May 1926. He was the son of Boris Delone, a mathematician. He graduated from the Moscow Engineering Physics Institute in 1951, and obtained his Ph.D at the Lebedev Physical Institute in the late 1950s. Delone is recognized for the first observations of multiphoton ionization, in 1965. : English translation in Delone, along with Maxim Ammosov and Vladimir P. Krainov, developed the ADK formula, relating tunneling ionization in laser fields. He was also a lecturer at the Moscow Institute of Physics and Technology. After the dissolution of the Soviet Union, he travelled abroad and worked on international collaborations on multiphoton physics. His son was Vadim Delaunay, a poet and dissident, who participated in the 1968 Red Square demonstration of protest against mili ...

Laser Field
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light which is ''coherent''. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum. Alternatively, temporal coherence can be used to produce ultrashort pulses of light wit ...

Scientists From Saint Petersburg
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have Terminal degree, advanced degrees in an area of science and pursue careers in various Sector (economic), sectors of the economy such as Academy, academia, Private industry, industry, Government sci ...

Scientific Paper
: ''For a broader class of literature, see Academic publishing.'' Scientific literature comprises scholarly publications that report original empirical and theoretical work in the natural and social sciences. Within an academic field, scientific literature is often referred to as the literature. Academic publishing is the process of contributing the results of one's research into the literature, which often requires a peer-review process. Original scientific research published for the first time in scientific journals is called the primary literature. Patents and technical reports, for minor research results and engineering and design work (including computer software), can also be considered primary literature. Secondary sources include review articles (which summarize the findings of published studies to highlight advances and new lines of research) and books (for large projects or broad arguments, including compilations of articles). Tertiary sources might include encycl ...

Prague Spring
The Prague Spring ( cs, Pražské jaro, sk, Pražská jar) was a period of political liberalization and mass protest in the Czechoslovak Socialist Republic. It began on 5 January 1968, when reformist Alexander Dubček was elected First Secretary of the Communist Party of Czechoslovakia (KSČ), and continued until 21 August 1968, when the Soviet Union and most of Warsaw Pact members invaded the country to suppress the reforms. The Prague Spring reforms were a strong attempt by Dubček to grant additional rights to the citizens of Czechoslovakia in an act of partial decentralization of the economy and democratization. The freedoms granted included a loosening of restrictions on the media, speech and travel. After national discussion of dividing the country into a federation of three republics, Bohemia, Moravia-Silesia and Slovakia, Dubček oversaw the decision to split into two, the Czech Socialist Republic and Slovak Socialist Republic. This dual federation was the only for ...

It was a protest by eight demonstrators against the Soviet invasion of Czechoslovakia (1968), invasion of Czechoslovakia on the night of 20–21 August 1968 by the Soviet Union and its Warsaw Pact allies, crushing the Prague spring, Prague Spring, the challenge to centralised planning and censorship by Communist Party of Czechoslovakia, communist leader Alexander Dubček. The protest took place at the Lobnoye Mesto (Place of Proclamation) on Red Square next to the Kremlin, to avoid any accusation of a violation of public order. It was a non-violent, sit-down demonstration. However, all but one of the protestors was quickly and roughly arrested by police and plainclothes KGB men. The protest, 25 August The protest began at noon as eight protesters (Larisa Bogoraz, Konstantin Babitsky, Vadim Delaunay, Vladimir Dremliuga, Pavel Litv ...

His grandfather, Boris Delaunay, was a prominent Soviet mathematician and creator of the Delaunay triangulation. Among his ancestors was marquis Bernard-René de Launay, the last governor of the Bastille, murdered by the attackers on that castle. Delaunay studied at Moscow matshkola ("Mathematical School") No. 2, one of the best in the country at that time, then at the Department of Philology at the Moscow Pedagogical Institute. As a student, he also work ...
