8694-429: The end of the 1920s. A new anti-religious campaign, launched in 1929, coincided with the collectivization of peasants; the destruction of churches in the cities peaked around 1932. In 1937 letters were written to the Central Committee of the Communist Party of the Soviet Union to rename Moscow to "Stalindar" or "Stalinodar". Stalin rejected this suggestion. During World War II, the Soviet State Committee of Defence and

8820-431: The expanding city in the later 19th century and was developed into a public municipal park in 1878. The suburban Savyolovsky Rail Terminal was built in 1902. In January 1905, the institution of the City Governor, or Mayor , was officially introduced, and Alexander Adrianov became Moscow's first official mayor. When Catherine II came to power in 1762, the city's filth and the smell of sewage were depicted by observers as

8946-425: The first major Russian computer, Relay Computer RVM-1 , though he liked to say his colleague N.I. Bessonov was the sole inventor. At the Moscow Institute for Theoretical and Experimental Physics (ITEF or ITEP) during 1950–1955 Kronod collaborated with physicists, among them Isaak Pomeranchuk and Lev Landau . For providing theoretical physics with numerical solutions he received the Stalin Prize and an Order of

In 2010s Moscow's Administration has launched some long duration projects like

9324-546: The government, and from 20 October the city was declared to be in a siege. Its remaining inhabitants built and manned antitank defenses, while the city was bombarded from the air. On 1 May 1944, a medal "For the defence of Moscow" and in 1947 another medal "In memory of the 800th anniversary of Moscow" was instituted. German and Soviet casualties during the battle have been debated, as sources provide different estimates. Total casualties between 30 September 1941, and 7 January 1942, are estimated to be between 248,000 and 400,000 for

9450-768: The greenest cities in the world. The city's name is thought to be derived from the Moskva River . Theories of the origin of the name of the river have been proposed. The most linguistically well-grounded and widely accepted is from the Proto-Balto-Slavic root * mŭzg -/ muzg - from the Proto-Indo-European * meu - "wet", so the name Moskva might signify a river at a wetland or marsh. Its cognates include Russian : музга , muzga "pool, puddle", Lithuanian : mazgoti and Latvian : mazgāt "to wash", Sanskrit : májjati "to drown", Latin : mergō "to dip, immerse". In many Slavic countries Moskov

9576-535: The lab has historically been a major wide area network hub. CERN is also the birthplace of the World Wide Web . The convention establishing CERN was ratified on 29 September 1954 by 12 countries in Western Europe. The acronym CERN originally represented the French words for Conseil Européen pour la Recherche Nucléaire ('European Council for Nuclear Research'), which was a provisional council for building

9702-518: The lab was being used for game playing, when the division was writing the Crazy Eights card game and chess trying to teach a machine to think. When the Communist Party reprimanded him in 1968 for cosigning a letter with many mathematicians in defense of the mathematician and logician Alexander Esenin-Volpin , a son of the poet Sergei Yesenin , the physicists were able to oust him from ITEP. He

9828-562: The laboratory, established by 12 European governments in 1952. During these early years, the council worked at the University of Copenhagen under the direction of Niels Bohr before moving to its present site near Geneva. The acronym was retained for the new laboratory after the provisional council was dissolved, even though the name changed to the current Organisation européenne pour la recherche nucléaire ('European Organization for Nuclear Research') in 1954. According to Lew Kowarski ,

9954-427: The latter forms came the modern Russian name Москва , Moskva , which is a result of morphological generalization with the numerous Slavic ā -stem nouns . The form Moskovĭ has left traces in other languages, including English: Moscow ; German : Moskau ; French : Moscou ; Portuguese : Moscou, Moscovo ; and Spanish : Moscú . Moscow has acquired epithets , such as The Third Rome . Moscow

Moscow serves as the reference point for the time zone used in most of European Russia , Belarus and

10206-540: The main Meyrin site, also known as the West Area, which was originally built in Switzerland alongside the French border, but has been extended to span the border since 1965. The French side is under Swiss jurisdiction and there is no obvious border within the site, apart from a line of marker stones. The SPS and LEP/LHC tunnels are almost entirely outside the main site, and are mostly buried under French farmland and invisible from

10332-459: The majority of Moscow's indigenous population. The first known reference to Moscow was in 1147, as a meeting place of Yuri Dolgorukiy and Sviatoslav Olgovich . At the time it was a minor town on the western border of Vladimir-Suzdal Principality. In 1156, Dolgorukiy fortified the town by creating a wooden wall; this structure became the Kremlin. In the course of the Mongol invasion of Kievan Rus' ,

10458-407: The medicine on himself. Kronrod had no medical degree but he was well-informed in medicine. Milil was a last resort for seriously ill patients and was administered by physicians in one case in a hospital ward A.A. Vishnevskiy reserved for treatments by Kronrod's method. Kronrod himself never gave the drug to patients and through physicians gave it away free. The drug was unapproved and a criminal case

10584-519: The medieval Muscovy state). He began fighting the Tatars, enlarged the territory of Muscovy, and enriched his capital city. By 1500 it had a population of 100,000 and was one of the largest cities in the world. He conquered the far larger principality of Novgorod to the north, which had been allied to the hostile Lithuanians. Thus he enlarged the territory sevenfold, from 430,000 to 2,800,000 square kilometres (170,000 to 1,080,000 square miles). He took control of

The road connecting Moscow with St. Petersburg, now the M10 highway , was completed in 1746, its Moscow end following the old Tver road, which had existed since the 16th century. It became known as Peterburskoye Schosse after it

10836-589: The most powerful cities in Russia. In 1380, prince Dmitry Donskoy of Moscow led a united Russian army to an important victory over the Mongols in the Battle of Kulikovo . Afterward, Moscow took the leading role in liberating Russia from Mongol domination. In 1480, Ivan III had finally broken the Russians free from Tatar control, and Moscow became the capital of an empire that would eventually encompass all of Russia and Siberia , and parts of many other lands. In 1462 Ivan III became Grand Prince of Moscow (then part of

10962-472: The name is reconstructed as * Москы , * Mosky , hence it was one of a few Slavic ū -stem nouns . As with other nouns of that declension, it had been undergoing a morphological transformation at the early stage of the development of the language, as a result, the first written references in the 12th century were Московь , Moskovĭ ( accusative case ), Москви , Moskvi ( locative case ), Москвe/Москвѣ , Moskve/Moskvě ( genitive case ). From

11088-477: The population doubled from 100,000 to 200,000, and it expanded beyond its ramparts in the latter part of the century. In the middle of the 17th century, 20% of Moscow suburb's inhabitants were from the Grand Duchy of Lithuania , being driven from their homeland by Muscovite invaders. By 1682, there were 692 households established north of the ramparts, by Ukrainians and Belarusians abducted from their hometowns in

11214-523: The population grew tenfold over the remaining duration of the Russian Empire, reaching 1.8 million by 1915. The 1770–1772 Russian plague killed up to 100,000 people in Moscow. By 1700, the building of cobbled roads had begun. In 1730, permanent street lights were introduced, and by 1867 many streets had a gaslight. In 1883, near the Prechistinskiye Gates, arc lamps were installed. In 1741 Moscow

From 1283 he acted as the ruler of an independent principality alongside Dmitry, who became Grand Duke of Vladimir . Daniel has been credited with founding the first Moscow monasteries, dedicated to the Lord's Epiphany and to Saint Daniel. Daniel ruled Moscow as Grand Duke until 1303 and established it as

11466-567: The research being performed there. At the sixth session of the CERN Council in Paris from 29 June to 1 July 1953, the convention establishing the organization was signed, subject to ratification, by 12 states. The convention was gradually ratified by the 12 founding Member States: Belgium, Denmark, France, the Federal Republic of Germany , Greece, Italy, the Netherlands, Norway, Sweden, Switzerland,

11592-464: The role of gender in computing. He employed women in ITEP's coding and card punching groups, believing that female computing staff members are more accurate than males. He also believed that in order to think, the male scientists qualified to use the computers needed to be free from operating them. The women did the input and quality assurance side by side with the men and for each month without an error received

11718-497: The search for the Higgs boson . When the 7 TeV experimental period ended, the LHC increased to 8 TeV (4 TeV per proton) starting March 2012, and soon began particle collisions at that energy. In July 2012, CERN scientists announced the discovery of a new sub-atomic particle that was later confirmed to be the Higgs boson . In March 2013, CERN announced that the measurements performed on the newly found particle allowed it to conclude that it

They have surface sites at points around them, either as the location of buildings associated with experiments or other facilities needed to operate the colliders such as cryogenic plants and access shafts. The experiments are located at the same underground level as the tunnels at these sites. Three of these experimental sites are in France, with ATLAS in Switzerland, and some of

12474-558: The theoretical description of the Higgs mechanism in the year after the Higgs boson was found by CERN experiments. CERN pioneered the introduction of TCP/IP for its intranet , beginning in 1984. This played an influential role in the adoption of the TCP/IP in Europe (see History of the Internet and Protocol Wars ). In 1989, the World Wide Web was invented at CERN by Tim Berners-Lee . Based on

12600-415: The time, instead of students merely reporting on the content of courses, Kronrod made his students undertake training exercises, even proving basic theorems themselves. The preparation required for this reduced the numbers of participants, but those who remained, including Robert Minlos and Anatoli Vitushkin , derived great benefit. Vitushkin described him as "witty and friendly". At his own request, Kronrod

12726-411: The two beams so that they smashed into each other. This is like "firing two needles across the Atlantic and getting them to hit each other" according to Steve Myers, director for accelerators and technology. On 30 March 2010, the LHC successfully collided two proton beams with 3.5 TeV of energy per proton, resulting in a 7 TeV collision energy. This was enough to start the main research program, including

12852-436: The urban area covers 5,891 square kilometers (2,275 sq mi), and the metropolitan area covers over 26,000 square kilometers (10,000 sq mi). Moscow is among the world's largest cities , being the most populous city in its entirety in Europe, the largest urban and metropolitan area in Europe, and the largest city by land area on the European continent. First documented in 1147, Moscow grew to serve as

12978-597: The wake of Russia's failures in the Crimean War in 1855–56, confidence in the ability of the state to maintain order in the slums eroded, and demands for improved public health put it back on the agenda. In 1903 the Moskvoretskaya water supply was completed. In November 1917, upon learning of the uprising in Petrograd , Moscow's Bolsheviks began their uprising .

Associate Members, Candidates: Three countries have observer status: Also observers are the following international organizations: Non-Member States (with dates of Co-operation Agreements) currently involved in CERN programmes are: CERN also has scientific contacts with

13860-526: Was accepted. He served twice, and was injured twice. He was awarded several medals, including Order of the Red Star . The second injury in 1943 hospitalised him for a year and he was discharged from the army in 1944. This injury made him an invalid of sorts for life. Kronrod was married and about this time his son was born. During next four years he continued his studies at the University, simultaneously working at

13986-541: Was also fired from his professorship. He then directed the mathematics laboratory at the Central Scientific Research Institute of Patent Information (CNIIPI) where he proposed patent reform to stimulate inventions. After gaining support he lost this position to an unsympathetic director. His last position was heading a Central Geophysical Expedition laboratory that processed drilling data where he made calculations for gas and oil exploration , but he

14112-420: Was awarded to Carlo Rubbia and Simon van der Meer for the developments that resulted in the discoveries of the W and Z bosons. The 1992 Nobel Prize for Physics was awarded to CERN staff researcher Georges Charpak "for his invention and development of particle detectors, in particular the multiwire proportional chamber ". The 2013 Nobel Prize for Physics was awarded to François Englert and Peter Higgs for

14238-490: Was brought against him. He regained his research records when a relative of the plaintiff required milil for treatment and the case was dismissed. He slowly recovered when a stroke took his speech and ability to read and write but was forced to resign at the Central Geophysical Expedition and stop all work on math. He saved his own life by asking to be soaked in a tub of very hot water for several hours after

14364-511: Was built in 1505–08 and augmented to its present height in 1600. A trading settlement, or posad , grew up to the east of the Kremlin, in the area known as Zaradye .

The Rurikids maintained large landholdings by practicing primogeniture , whereby all land was passed to the eldest sons. By 1304, Yury of Moscow contested with Mikhail of Tver for the throne of the principality of Vladimir . Ivan I eventually defeated Tver to become

14742-468: Was called simply "Sasha" by his students. He was considered to be a prophet in his field. The Kronod circle met between 1946 and 1953. Kronrod's position was formally at the Institute of Physics, which meant that his students had to register with other advisers, accounting for the decline of the circle into a series of friendly meetings. When he defended thesis in 1949, his committee including Mstislav Keldysh , Andrey Kolmogorov and Dmitrii Menshov bypassed

14868-505: Was endorsed by the four main LHC collaborations ( ALICE , ATLAS , CMS and LHCb ). The open data policy complements the open access policy, addressing the public release of scientific data collected by LHC experiments after a suitable embargo period. Prior to this open data policy, guidelines for data preservation, access and reuse were implemented by each collaboration individually through their own policies which are updated when necessary. The European Strategy for Particle Physics,

14994-507: Was erected around the city, including an area on the right bank of the Moscow River. As an outermost line of defense, a chain of strongly fortified monasteries was established beyond the ramparts to the south and east, principally the Novodevichy Convent and Donskoy , Danilov , Simonov , Novospasskiy , and Andronikov monasteries, most of which now house museums. From its ramparts, the city became poetically known as Bielokamennaya ,

15120-421: Was established in Moscow. Vladimir Lenin , fearing invasion, moved the capital back to Moscow on 12 March 1918. The Kremlin once again became the seat of power, political centre of the new state. With the change in values imposed by communist ideology , the tradition of preserving cultural heritage was broken. Independent preservation societies, even those that defended only secular landmarks, were disbanded by

15246-538: Was lowered down a special shaft at in March 2005. The LHC has begun to generate vast quantities of data, which CERN streams to laboratories around the world for distributed processing, making use of a specialized grid infrastructure, the LHC Computing Grid . In April 2005, a trial successfully streamed 600 MB/s to seven different sites across the world. In August 2008, the initial particle beams were injected into

A policy said finished programs had to be re-examined if they ran for more than ten minutes. program written by (a male name) coded by (a female name) coding checked by (a female name) punched by (a female name) punching checked by (a female name) Typical appearance of a program-writing form in Kronrod's department at ITEP, as remembered by Landis and Yaglom . Kronrod rewarded accuracy. He held what today are controversial views on

15498-517: Was not challenged by this work. He re-examined his goals and soon changed course. Kronrod decided that his best work was to help others and most importantly the terminally ill. He spent his fortune developing milil from a sour milk extract for cancer patients, to fill a shortage of anabol , an expensive drug developed in small quantities by his acquaintance Bogdanov in Bulgaria. He was promised but never acquired an animal testing laboratory so he tested

15624-559: Was officially named Новая Москва (New Moscow). Moscow is situated on the banks of the Moskva River , which flows for just over 500 km (311 mi) through the East European Plain in central Russia, not far from the natural border of the forest and forest- steppe zone. 49 bridges span the river and its canals within the city's limits. The elevation of Moscow at the All-Russia Exhibition Center (VVC), where

When Napoleon invaded Russia in 1812, the Moscovites were evacuated. The Moscow fire was principally the effect of Russian sabotage. Napoleon's Grande Armée was forced to retreat and nearly annihilated by the devastating Russian winter. In 1813, following

15876-616: Was surrounded by a barricade 40 kilometres (25 mi) long, the Kamer-Kollezhskiy barrier, with 16 gates at which customs tolls were collected. Its line is traced today by several streets called val ("ramparts"). In the early 19th century, the Arch of Konstantino-Elenensky gate was paved with bricks, but the Spassky Gate was the main front gate of the Kremlin and used for royal entrances. From this gate, wooden and stone bridges stretched across
