Amfibia
Amfibia (often spelled "Amphibia" or "Amphibian") is a Soviet watch that in the West would be called a Dive watch. Produced in large quantities for the Soviet and Russian military, these watches gained significant popularity worldwide. The Vostok watch factory created the first Soviet Amphibia watch in 1967. Around the same time, Raketa also started producing a diving watch. Poljot followed with their own version in 1972. History The Amphibia creation was led by Vostok's chief of their new design bureau. The objectives were to create a watch that was competitive with contemporary diving watch such as the Blancpain 50 Fathoms, the Rolex Submariner and the watches using the compressor case, and to create a watch that could operate reliably at the temperature and pressure of 20 atmospheres(and later 30 atmospheres). The chief designers were Mikhail Fedorovich Novikov and Vera Fedorovna Belova. According to Mikhail Novikov, the name “Amphibia” was chosen in a contest among ...

Vostok Watches
Vostok Watch Makers, Inc. (russian: Восток; literally meaning "East") is a Russian watchmaker based in Chistopol, Tatarstan, Russia. The company produces mainly rugged military and amfibia mechanical watches. It also makes clocks and watch movements for other watch brands. History The Vostok Watch Makers company was founded in 1942 when one of the Moscow watch-making plants of the First Moscow Watch Factory was evacuated to Chistopol, a small town located on the Kama River in Tatarstan.''International Watch'' magazine, Nov. 2006, pg. 187 Only defence equipment was produced during the war years, but as soon as the war was over, the company started making mechanical wristwatches. In 2006, Vostok Watch Makers began marketing another line of watches branded "Amphibia". Despite the introduction of the new lines of ''Komandirskie'' and ''Amphibia'', the "classic" models (mostly designed in the 1960s and 1970s) of these lines were still in production (as of 2021).

Salyut 4
Salyut 4 (DOS 4) (russian: Салют-4; English translation: Salute 4) was a Salyut space station launched on December 26, 1974 into an orbit with an apogee of 355 km, a perigee of 343 km and an orbital inclination of 51.6 degrees. It was essentially a copy of the DOS 3 (or Kosmos 557), and unlike its ill-fated sibling it was a complete success. Three crews attempted to make stays aboard Salyut 4 ( Soyuz 17 and Soyuz 18 docked; Soyuz 18a suffered a launch abort). The second stay was for 63 days duration, and an unmanned capsule, called Soyuz 20, remained docked to the station for three months, proving the system's long-term durability despite some deterioration of the environmental system during Soyuz 18's mission. Salyut 4 was deorbited February 2, 1977, and re-entered the Earth's atmosphere on February 3. Description Salyut 4 represented the second phase of DOS civilian space station. Although the basic design of Salyut 1 was retained, it switched to three large sol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watch Models
A watch is a portable timepiece intended to be carried or worn by a person. It is designed to keep a consistent movement despite the motions caused by the person's activities. A wristwatch is designed to be worn around the wrist, attached by a watch strap or other type of bracelet, including metal bands, leather straps or any other kind of bracelet. A pocket watch is designed for a person to carry in a pocket, often attached to a chain. Watches were developed in the 17th century from spring-powered clocks, which appeared as early as the 14th century. During most of its history the watch was a mechanical device, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. These are called ''mechanical watches''. In the 1960s the electronic ''quartz watch'' was invented, which was powered by a battery and kept time with a vibrating quartz crystal. By the 1980s the quartz watch had taken over most of the market from the mechani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Life Aquatic With Steve Zissou
''The Life Aquatic with Steve Zissou'' is a 2004 American adventure comedy-drama film written by Wes Anderson and Noah Baumbach and directed by Anderson. It is Anderson's fourth feature-length film and was released in the United States on December 25, 2004. The film stars Bill Murray as Steve Zissou, an eccentric oceanographer who sets out to exact revenge on the "jaguar shark" that ate his partner Esteban. Zissou is both a parody of and homage to French diving pioneer Jacques Cousteau, to whom the film is dedicated. The film also features Owen Wilson, Cate Blanchett, Willem Dafoe, Michael Gambon, Jeff Goldblum, Anjelica Huston and Bud Cort. Seu Jorge has a minor part, but contributes heavily to the film's soundtrack. It was filmed in and around Naples, Ponza, and the Italian Riviera. The film was released to mixed reviews and was a box office flop. In the decade following its release it has garnered a cult following, and is now viewed more positively by both critics ...

Elasticity (physics)
In physics and materials science, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. Solid objects will deform when adequate loads are applied to them; if the material is elastic, the object will return to its initial shape and size after removal. This is in contrast to ''plasticity'', in which the object fails to do so and instead remains in its deformed state. The physical reasons for elastic behavior can be quite different for different materials. In metals, the atomic lattice changes size and shape when forces are applied (energy is added to the system). When forces are removed, the lattice goes back to the original lower energy state. For rubbers and other polymers, elasticity is caused by the stretching of polymer chains when forces are applied. Hooke's law states that the force required to deform elastic objects should be directly proportional to the distance of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lucite
Poly(methyl methacrylate) (PMMA) belongs to a group of materials called engineering plastics. It is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Plexiglas, Acrylite, Astariglas, Lucite, Perclax, and Perspex, among several others ( see below). This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can also be used as a casting resin, in inks and coatings, and for many other purposes. Although not a type of familiar silica-based glass, the substance, like many thermoplastics, is often technically classified as a type of glass, in that it is a non-crystalline vitreous substance—hence its occasional historic designation as ''acrylic glass''. Chemically, it is the synthetic polymer of methyl methacrylate. It was developed in 1928 in several different laboratories by many chemists, such as William Chalmers, Otto Röhm, and Walter Bauer, and first brought t ...

Compressor Case
A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. The main distinction is that the focus of a compressor is to change the density or volume of the fluid, which is mostly only achievable on gases. Gases are compressible, while liquids are relatively incompressible, so compressors are rarely used for liquids. The main action of a pump is to pressurize and transport liquids. Many compressors can be staged, that is, the fluid is compressed several times in steps or stages, to increase discharge pressure. Often, the second stage is physically smaller than the primary stage, to accommodate the already compressed gas without reducing its pressure. Each stage further compresses the gas and increases its pressure and also temperature (if inter cooling between sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmosphere (unit)
The standard atmosphere (symbol: atm) is a unit of pressure defined as Pa. It is sometimes used as a ''reference pressure'' or ''standard pressure''. It is approximately equal to Earth's average atmospheric pressure at sea level. History The standard atmosphere was originally defined as the pressure exerted by 760 mm of mercury at and standard gravity (''g''n = ). It was used as a reference condition for physical and chemical properties, and was implicit in the definition of the Celsius temperature scale, which defined as the boiling point of water at this pressure. In 1954, the 10th General Conference on Weights and Measures (CGPM) adopted ''standard atmosphere'' for general use and affirmed its definition of being precisely equal to dynes per square centimetre (). This defined both temperature and pressure independent of the properties of particular substance. In addition, the CGPM noted that there had been some misapprehension that it "led some physicists to believe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
