Foucault Pendulum
The Foucault pendulum or Foucault's pendulum is a simple device named after French physicist Léon Foucault, conceived as an experiment to demonstrate the Earth's rotation. A long and heavy pendulum suspended from the high roof above a circular area was monitored over an extended time period, showing that the plane of oscillation rotated. The pendulum was introduced in 1851 and was the first experiment to give simple, direct evidence of the Earth's rotation. Foucault pendulums today are popular displays in science museums and universities. Original Foucault pendulum The first public exhibition of a Foucault pendulum took place in February 1851 in the Meridian of the Paris Observatory. A few weeks later, Foucault made his most famous pendulum when he suspended a brass-coated lead bob (physics), bob with a wire from the dome of the Panthéon, Paris. The proper period of the pendulum was approximately 2\pi\sqrt\approx 16.5 \,\mathrm. Because the latitude of its location was \ph ...

Museums In Kyiv Oblast
A museum ( ; plural museums or, rarely, musea) is a building or institution that cares for and displays a collection of artifacts and other objects of artistic, cultural, historical, or scientific importance. Many public museums make these items available for public viewing through exhibits that may be permanent or temporary. The largest museums are located in major cities throughout the world, while thousands of local museums exist in smaller cities, towns, and rural areas. Museums have varying aims, ranging from the conservation and documentation of their collection, serving researchers and specialists, to catering to the general public. The goal of serving researchers is not only scientific, but intended to serve the general public. There are many types of museums, including art museums, natural history museums, science museums, war museums, and children's museums. According to the International Council of Museums (ICOM), there are more than 55,000 museums in 202 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mars 6
Mars 6 (), also known as 3MP No.50P was a Soviet spacecraft launched to explore Mars. A 3MP bus spacecraft launched as part of the Mars program, it consisted of a lander, and a coast stage with instruments to study Mars as it flew past. Spacecraft The Mars 6 spacecraft carried an array of instruments to study Mars. The lander was equipped with a thermometer and barometer to determine the surface conditions, an accelerometer and radio altimeter for descent, and instruments to analyse the surface material including a mass spectrometer. The coast stage, or bus, carried a magnetometer, plasma traps, cosmic ray and micrometeoroid detectors, and an instrument to study proton and electron fluxes from the Sun. Built by Lavochkin, Mars 6 was the first of two 3MP spacecraft launched to Mars in 1973 and was followed by Mars 7. Two orbiters, Mars 4 and Mars 5, were launched earlier in the 1973 Mars launch window and were expected to relay data for the two landers. However, Mars 4 failed to ...

Soyuz 23
Soyuz 23 (russian: Союз 23, ''Union 23'') was an October, 1976, Soviet crewed space flight, the second to the Salyut 5 space station. Cosmonauts Vyacheslav Zudov and Valery Rozhdestvensky arrived at the station, but an equipment malfunction did not allow docking and the mission had to be aborted. The crew returned to Earth, but landed on partially frozen Lake Tengiz, the first crewed splashdown in the Soviet space program. While there was no concern about any immediate threat to the crew, the capsule sank under the surface of the frozen lake, and recovery took nine hours owing to fog and other adverse conditions. The landing marked the only example of an unintentional splashdown of a crewed spacecraft to date. Crew Backup crew Reserve crew Mission highlights Soyuz 23 was launched 14 October 1976 with an estimated 73- to 85-day mission planned aboard the orbiting Salyut 5 space station.

Space Suit
A space suit or spacesuit is a garment worn to keep a human alive in the harsh environment of outer space, vacuum and temperature extremes. Space suits are often worn inside spacecraft as a safety precaution in case of loss of cabin pressure, and are necessary for extravehicular activity (EVA), work done outside spacecraft. Space suits have been worn for such work in Earth orbit, on the surface of the Moon, and en route back to Earth from the Moon. Modern space suits augment the basic pressure garment with a complex system of equipment and environmental systems designed to keep the wearer comfortable, and to minimize the effort required to bend the limbs, resisting a soft pressure garment's natural tendency to stiffen against the vacuum. A self-contained oxygen supply and environmental control system is frequently employed to allow complete freedom of movement, independent of the spacecraft. Three types of space suits exist for different purposes: IVA (intravehicular activity) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minsk Family Of Computers
''Minsk'' family of mainframe computers was developed and produced in the Byelorussian SSR from 1959 to 1975. Models The MINSK-1 was a vacuum-tube digital computer that went into production in 1960. The MINSK-2 was a solid-state digital computer that went into production in 1962. The MINSK-22 was a modified version of Minsk-2 that went into production in 1965. The MINSK-23 went into production in 1966. The most advanced model was ''Minsk-32'', developed in 1968. It supported COBOL, FORTRAN and ALGAMS (a version of ALGOL). This and earlier versions also used a machine-oriented language called ''AKI'' (''AvtoKod "Inzhener"'', i.e., " Engineer's Autocode"). It stood somewhere between the native assembly language ''SSK'' (''Sistema Simvolicheskogo Kodirovaniya'', or "System of symbolic coding") and higher-level languages, like FORTRAN. The word size was 31 bits for Minsk-1 and 37 bits for the other models. At one point the Minsk-222 (an upgraded prototype based on the most popu ...
