Fast Universal Digital Computer M-2
The M-2 () was a computer developed at the Laboratory of Electrical Systems in the Institute of Energy of the USSR Academy of Sciences The Academy of Sciences of the Soviet Union was the highest scientific institution of the Soviet Union from 1925 to 1991, uniting the country's leading scientists, subordinated directly to the Council of Ministers of the Soviet Union (until 1946 .... The successor to the M-1, it was developed in 1952 by a team of engineers led by I.S. Brook (or Bruk). The computer was developed and assembled in the period between April and December 1952. In 1953 M-2 became fully operational and was used for solving applied problems on round-the-clock basis, mostly having to do with nuclear fission and rocket design. M-2 was the basis for several other Soviet computers, some of them developed at other research institutes.

Russian Alphabet
The Russian alphabet (russian: ру́сский алфави́т, russkiy alfavit, , label=none, or russian: ру́сская а́збука, russkaya azbuka, label=none, more traditionally) is the script used to write the Russian language. It comes from the Cyrillic script, which was devised in the 9th century for the first Slavic literary language, Old Slavonic. Initially an old variant of the Bulgarian alphabet, it became used in the Kievan Rusʹ since the 10th century to write what would become the Russian language. The modern Russian alphabet consists of 33 letters: twenty consonants (, , , , , , , , , , , , , , , , , , , ), ten vowels (, , , , , , , , , ), a semivowel / consonant (), and two modifier letters or "signs" (, ) that alter pronunciation of a preceding consonant or a following vowel. Letters : An alternative form of the letter El () closely resembles the Greek letter lambda (). Historic letters Letters eliminated in 1917–18 * — Identical ...

Unicode
Unicode, formally The Unicode Standard,The formal version reference is is an information technology Technical standard, standard for the consistent character encoding, encoding, representation, and handling of Character (computing), text expressed in most of the world's writing systems. The standard, which is maintained by the Unicode Consortium, defines as of the current version (15.0) 149,186 characters covering 161 modern and historic script (Unicode), scripts, as well as symbols, emoji (including in colors), and non-visual control and formatting codes. Unicode's success at unifying character sets has led to its widespread and predominant use in the internationalization and localization of computer software. The standard has been implemented in many recent technologies, including modern operating systems, XML, and most modern programming languages. The Unicode character repertoire is synchronized with Universal Coded Character Set, ISO/IEC 10646, each being code-for-code id ...

English Alphabet
The alphabet for Modern English is a Latin-script alphabet consisting of 26 letters, each having an upper- and lower-case form. The word ''alphabet'' is a compound of the first two letters of the Greek alphabet, '' alpha'' and '' beta''. The alphabet originated around the 7th century CE to write Old English from Latin script. Since then, letters have been added or removed to give the current letters: The exact shape of printed letters varies depending on the typeface (and font), and the standard printed form may differ significantly from the shape of handwritten letters (which varies between individuals), especially cursive. English Vowels and English Consonants. The English alphabet has 6 vowels and 20 consonants. Written English has a large number of digraphs (e.g., ''would'', ''beak'', ''moat''); it stands out (almost uniquely) as a European language without diacritics in native words. The only exceptions are: * a diaeresis (e.g., "coöperation") may be us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USSR Academy Of Sciences
The Academy of Sciences of the Soviet Union was the highest scientific institution of the Soviet Union from 1925 to 1991, uniting the country's leading scientists, subordinated directly to the Council of Ministers of the Soviet Union (until 1946 – to the Council of People's Commissars of the Soviet Union). In 1991, by the decree of the President of the Russian Soviet Federative Socialist Republic, the Russian Academy of Sciences was established on the basis of the Academy of Sciences of the Soviet Union. History Creation of the Academy of Sciences of the Soviet Union The Academy of Sciences of the Soviet Union was formed by a resolution of the Central Executive Committee and the Council of People's Commissars of the Soviet Union dated July 27, 1925 on the basis of the Russian Academy of Sciences (before the February Revolution – the Imperial Saint Petersburg Academy of Sciences). In the first years of Soviet Russia, the Institute of the Academy of Sciences was perceived ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Digital Computer M-1
The project to build the M-1 or Automatic Digital Computer (ADC) M-1 () was completed at the end of 1951, at the Energetics Institute of the USSR Academy of Sciences. Overview In charge of the Laboratory of Electrosystems was Isaak Semenovich Brook (or Bruk), who obtained the first domestic patent with the title "Digital Computer with Common Bus" in 1948. Work to build the computer based on Brook's design began in 1950. Parts were very difficult to get due to postwar rationing. On the other hand, due to availability of copper oxide diodes which were brought as trophies from Germany, the machine had the lowest lamp count of contemporary designs, at 730. The memory was based on an original invention of an electrostatic memory using the ordinary oscilloscope cathode-ray tube. Each tube was capable of holding 32 words, 25 bit each. The computer had 8 such tubes for a total fast memory of 256 machine words. The computer turned out to work rather reliably and was immediately put to ...

Nuclear Fission
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay. Nuclear fission of heavy elements was discovered on Monday 19 December 1938, by German chemist Otto Hahn and his assistant Fritz Strassmann in cooperation with Austrian-Swedish physicist Lise Meitner. Hahn understood that a "burst" of the atomic nuclei had occurred. Meitner explained it theoretically in January 1939 along with her nephew Otto Robert Frisch. Frisch named the process by analogy with biological fission of living cells. For heavy nuclides, it is an exothermic reaction which can release large amounts of energy both as electromagnetic radiation and as kinetic energy of the fragments (heating the bulk material where fission takes place). Like nuclear fusion, for fission to produce energy, the total binding energy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Computer Systems
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk (Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government that ...
