Arkadiy Migdal
Arkady Beynusovich (Benediktovich) Migdal (russian: Арка́дий Бе́йнусович (Бенеди́ктович) Мигда́л; Lida, Russian Empire, 11 March 1911 – Princeton, United States, 9 February 1991) was a Soviet physicist and member of the USSR Academy of Sciences. He developed the formula that accounts for the Landau–Pomeranchuk–Migdal effect, a reduction of the bremsstrahlung and pair production cross sections at high energies or high matter densities. Biography Arkady Migdal, whose father was a Jewish pharmacist, graduated from secondary school in Petrograd. In 1927 he published his first physics paper. He studied at Leningrad State University but was expelled in 1931 for his "non-proletarian origin". In 1933 he was arrested and imprisoned for 70 days. He graduated from Leningrad State University in 1936 with a Russian Candidate of Sciences degree (Ph.D.). His thesis advisor was Vladimir Fock. Migdal was a postdoc at the Leningrad Institute of Physics a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lida
Lida ( be, Лі́да ; russian: Ли́да ; lt, Lyda; lv, Ļida; pl, Lida ; yi, לידע, Lyde) is a city 168 km (104 mi) west of Minsk in western Belarus in Grodno Region. Etymology The name ''Lida'' arises from its Lithuanian name ''Lyda'', which derives from ''lydimas'', meaning "slash-and-burn" agricultural method or a plot of land prepared in this way. Names in other languages are spelled as pl, Lida and yi, לידע. History Early history, Grand Duchy of Lithuania and the Polish–Lithuanian Commonwealth There are passing mentions of Lida in chronicles from 1180. Until the early 14th century, the settlement at Lida was a wooden fortress in Lithuania proper. In 1323, the Grand Duke of Lithuania Gediminas built a brick fortress there. The generally considered founding year of Lida is 1380. The fortress withstood Crusader attacks from Prussia in 1392 and 1394 but was burned to the ground in 1710. Following the death of Gediminas, when Lithuania was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Neutron Star
A neutron star is the collapsed core of a massive supergiant star, which had a total mass of between 10 and 25 solar masses, possibly more if the star was especially metal-rich. Except for black holes and some hypothetical objects (e.g. white holes, quark stars, and strange stars), neutron stars are the smallest and densest currently known class of stellar objects. Neutron stars have a radius on the order of and a mass of about 1.4 solar masses. They result from the supernova explosion of a massive star, combined with gravitational collapse, that compresses the core past white dwarf star density to that of atomic nuclei. Once formed, they no longer actively generate heat, and cool over time; however, they may still evolve further through collision or accretion. Most of the basic models for these objects imply that neutron stars are composed almost entirely of neutrons (subatomic particles with no net electrical charge and with slightly larger mass than protons); the electro ...

Nagasaki
is the capital and the largest city of Nagasaki Prefecture on the island of Kyushu in Japan. It became the sole port used for trade with the Portuguese and Dutch during the 16th through 19th centuries. The Hidden Christian Sites in the Nagasaki Region have been recognized and included in the UNESCO World Heritage List. Part of Nagasaki was home to a major Imperial Japanese Navy base during the First Sino-Japanese War and Russo-Japanese War. Near the end of World War II, the American atomic bombings of Hiroshima and Nagasaki made Nagasaki the second and, to date, last city in the world to experience a nuclear attack (at 11:02 am, August 9, 1945 'Japan Standard Time (UTC+9)'). , the city has an estimated population of 407,624 and a population density of 1,004 people per km2. The total area is . History Nagasaki as a Jesuit port of call The first contact with Portuguese explorers occurred in 1543. An early visitor was Fernão Mendes Pinto, who came from Sagres ...

Hiroshima
is the capital of Hiroshima Prefecture in Japan. , the city had an estimated population of 1,199,391. The gross domestic product (GDP) in Greater Hiroshima, Hiroshima Urban Employment Area, was US$61.3 billion as of 2010. Kazumi Matsui has been the city's mayor since April 2011. Hiroshima was founded in 1589 as a castle town on the Ōta River delta. Following the Meiji Restoration in 1868, Hiroshima rapidly transformed into a major urban center and industrial hub. In 1889, Hiroshima officially gained city status. The city was a center of military activities during the imperial era, playing significant roles such as in the First Sino-Japanese War, the Russo-Japanese War, and the two world wars. Hiroshima was the first military target of a nuclear weapon in human history. This occurred on August 6, 1945, at 8:15 a.m., when the United States Army Air Forces (USAAF) dropped the atomic bomb "Little Boy" on the city. Most of Hiroshima was destroyed, and by the end of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Abram Alikhanov
Abram Isaakovich Alikhanov (; russian: Абрам Исаакович Алиханов, born Alikhanian; 8 December 1970) was a Soviet Armenian experimental physicist who specialized in particle and nuclear physics. He was one of the Soviet Union's leading physicists. Alikhanov studied X-rays and cosmic rays before joining the Soviet atomic bomb project. Between 1945 and 1968 he directed the Institute for Theoretical and Experimental Physics (ITEP) in Moscow, which was named after him in 2004.

Landau Institute For Theoretical Physics
The L. D. Landau Institute for Theoretical Physics (russian: link=no, Институт теоретической физики имени Л. Д. Ландау (ИТФ)) of the Russian Academy of Sciences is a research institution, located in the small town of Chernogolovka near Moscow (there is also a subdivision in Moscow, on the territory of the P. L. Kapitza Institute for Physical Problems). History The Landau Institute was formed in 1964 to keep the ''Landau school'' alive after the tragic car accident of Lev D. Landau. Since its foundation, the institute grew rapidly to about one hundred scientists, becoming one of the worldwide best-known and leading institutes for theoretical physics. Unlike many other scientific centers in Russia, the Landau Institute had the strength to cope with the crisis of the nineties in the last century. Although about one half of the scientists accepted positions at leading scientific centers and universities abroad, most of them kept ties with ...
