Robert Hanbury Brown
Robert Hanbury Brown, AC FRS (31 August 1916 – 16 January 2002) was a British astronomer and physicist born in Aruvankadu, India. He made notable contributions to the development of radar and later conducted pioneering work in the field of radio astronomy. With Richard Q. Twiss he developed the Hanbury Brown and Twiss effect leading to the creation of intensity interferometers.

States And Territories Of India
India is a federal union comprising 28 states and 8 union territories, with a total of 36 entities. The states and union territories are further subdivided into districts and smaller administrative divisions. History Pre-independence The Indian subcontinent has been ruled by many different ethnic groups throughout its history, each instituting their own policies of administrative division in the region. The British Raj mostly retained the administrative structure of the preceding Mughal Empire. India was divided into provinces (also called Presidencies), directly governed by the British, and princely states, which were nominally controlled by a local prince or raja loyal to the British Empire, which held ''de facto'' sovereignty ( suzerainty) over the princely states. 1947–1950 Between 1947 and 1950 the territories of the princely states were politically integrated into the Indian union. Most were merged into existing provinces; others were organised into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intensity Interferometer
An intensity interferometer is the name given to devices that use the Hanbury Brown and Twiss effect. In astronomy, the most common use of such an astronomical interferometer is to determine the apparent angular diameter of a radio source or star. If the distance to the object can then be determined by parallax or some other method, the physical diameter of the star can then be inferred. An example of an optical intensity interferometer is the Narrabri Stellar Intensity Interferometer. In quantum optics, some devices which take advantage of correlation and anti-correlation effects in beams of photons might be said to be intensity interferometers, although the term is usually reserved for observatories. An intensity interferometer is built from two light detectors, typically either radio antenna or optical telescopes with photomultiplier tubes (PMTs), separated by some distance, called the baseline. Both detectors are pointed at the same astronomical source, and intensity measureme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nilgiri Tea
Nilgiri tea is a drink made by infusing leaves of ''Camellia sinensis'' that is grown and processed in the Nilgiris district in Tamil Nadu, India. The leaves are processed as black tea, though some estates have expanded their product offerings to include leaves suitable for making green, white and oolong teas. It is generally described as being a brisk, fragrant and full-bodied tea. The region produces both rolled and crush, tear, curl tea and it is predominantly used for blending. Nilgiri tea is also used for making iced tea and instant tea. ''Camellia sinensis var. sinensis'' was introduced to Nilgiri Mountains by the British in 1835 from seeds shipped from China. Commercial production commenced in the 1860s, where the industry would evolve to include a mixture of many small growers with a few large corporate estates and the government-owned Tamil Nadu Tea Plantation established for the purpose of assisting in repatriating Indian Tamils from Sri Lanka. Its fertile soils loc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cordite
Cordite is a family of smokeless propellants developed and produced in the United Kingdom since 1889 to replace black powder as a military propellant. Like modern gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance. These produce a subsonic deflagration wave rather than the supersonic detonation wave produced by brisants, or high explosives. The hot gases produced by burning gunpowder or cordite generate sufficient pressure to propel a bullet or shell to its target, but not so quickly as to routinely destroy the barrel of the gun. Cordite was used initially in the .303 British, Mark I and II, standard rifle cartridge between 1891 and 1915; shortages of cordite in World War I led to the creation of the "Devil's Porridge" munitions factory (HM Factory, Gretna) on the English-Scottish border, which produced 800 tonnes of cordite per annum. The UK also imported some United States–developed smokeless powders for us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
