Lovell Telescope
The Lovell Telescope is a radio telescope at Jodrell Bank Observatory, near Goostrey, Cheshire in the north-west of England. When construction was finished in 1957, the telescope was the largest steerable dish radio telescope in the world at 76.2 m (250 ft) in diameter; it is now the third-largest, after the Green Bank telescope in West Virginia, United States, and the Effelsberg telescope in Germany. It was originally known as the "250 ft telescope" or the Radio Telescope at Jodrell Bank, before becoming the Mark I telescope around 1961 when future telescopes (the Mark II, III, and IV) were being discussed.Lovell, ''The Jodrell Bank Telescopes'' It was renamed to the Lovell Telescope in 1987 after Sir Bernard Lovell, and became a Grade I listed building in 1988. The telescope forms part of the MERLIN and European VLBI Network arrays of radio telescopes. Both Bernard Lovell and Charles Husband were knighted for their roles in creating the telescope.

Radio Telescope
A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky. Radio telescopes are the main observing instrument used in radio astronomy, which studies the radio frequency portion of the electromagnetic spectrum emitted by astronomical objects, just as optical telescopes are the main observing instrument used in traditional optical astronomy which studies the light wave portion of the spectrum coming from astronomical objects. Unlike optical telescopes, radio telescopes can be used in the daytime as well as at night. Since astronomical radio sources such as planets, stars, nebulas and galaxies are very far away, the radio waves coming from them are extremely weak, so radio telescopes require very large antennas to collect enough radio energy to study them, and extremely sensitive receiving equipment. Radio telescopes are typically large parabolic ("dish") antennas similar to those employed in tracking an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winter Hill (Lancashire)
Winter Hill is a hill on the border of the boroughs of Chorley, Blackburn with Darwen and Bolton, in the historic county of Lancashire in North West England. It is located on Rivington Moor, Chorley and is high. Part of the West Pennine Moors, it is a popular walking area, and has been the site of mining activity, aeroplane disasters and murders. Its prominent position made it the ideal site for the Winter Hill TV Mast, transmitting to a large part of North West England. There is also a number of other telecommunication masts and towers around the summit and side of the hill for mobile phones, Professional Mobile Radio users and emergency services. Lancashire Constabulary was the first to use the site for one of their base stations in 1950; they had to build the road and it is said to have been built by policemen. Paths to the summit lead from Belmont (in Blackburn with Darwen), Rivington (in Chorley borough), and Horwich and Blackrod (in Bolton borough). The summit can al ...

Bogie
A bogie ( ) (in some senses called a truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used. ...

Department Of Scientific And Industrial Research (United Kingdom)
The Department of Scientific and Industrial Research was a department of the British Government responsible for the organisation, development, and encouragement of scientific and industrial research. At the outbreak of the First World War "Britain found ... it was dangerously dependent on enemy industries". At the request of the Board of Trade, the Board of Education prepared a White Paper under the chairmanship of Sir William McCormick. The DSIR was set up to fill the roles that the White Paper specified: "to finance worthy research proposals, to award research fellowships and studentships n universities and to encourage the development of research associations in private industry and research facilities in university science departments. trapidly assumed a key role in coordinating government aid to university research. It maintained these roles until 1965. The annual budget during its first year, 1915, was £1,000,000. History Before the twentieth century, the government was ...

HMS Royal Sovereign (05)
HMS ''Royal Sovereign'' (pennant number 05) was a (also known as ''Royal Sovereign'' and R-class) battleship of the Royal Navy displacing and armed with eight guns in four twin-gun turrets. She was laid down in January 1914 and launched in April 1915; she was completed in May 1916, but was not ready for service in time to participate in the Battle of Jutland at the end of the month. She served with the Grand Fleet for the remainder of the First World War, but did not see action. In the early 1930s, she was assigned to the Mediterranean Fleet and based in Malta. Unlike the s, ''Royal Sovereign'' and her sisters were not modernised during the interwar period. Only minor alterations to her anti-aircraft battery were effected before the outbreak of World War II in September 1939. Assigned to the Home Fleet, the ship was tasked with convoy protection until May 1940, when she returned to the Mediterranean Fleet. ''Royal Sovereign'' was present during the Battle of Calabria in Jul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Revenge (06)
HMS ''Revenge'' (pennant number: 06) was the lead ship of five super-dreadnought battleships built for the Royal Navy during the First World War in the mid-1910s. The ships were developments of the s, with reductions in size and speed to offset increases in armour protection whilst retaining the same main battery of eight guns. She was laid down in 1913, launched in 1915 and commissioned in February 1916, early enough to be worked up to see action with the Grand Fleet at the Battle of Jutland in May that year. During the engagement, she engaged German battlecruisers, damaging two of them before being forced to turn away to avoid torpedoes that damaged her squadron flagship and caused the squadron to lose contact with the rest of the fleet. ''Revenge'' emerged from the battle unscathed, but she saw no further action during the war, as the British and German fleets turned to more cautious strategies owing to the risk of submarines and naval mines. During the 1920s and 1930s, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was List of wars and anthropogenic disasters by death toll, one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific Ocean, Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in Genocides in history (World War I through World War II), genocides within the Ottoman Empire and in the Spanish flu, 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising French Third Republic, France, Russia, and British Empire, Britain) and the Triple A ...

BL 15 Inch Mk I Naval Gun
The BL 15-inch Mark I succeeded the BL 13.5-inch Mk V naval gun. It was the first British 15-inch (381 mm) gun design and the most widely used and longest lasting of any British designs, and arguably the most successful heavy gun ever developed by the Royal Navy. It was deployed on capital ships from 1915 until 1959 and was a key Royal Navy gun in both World Wars. Design Gun This gun was an enlarged version of the successful BL 13.5-inch Mk V naval gun. It was specifically intended to arm the new s as part of the British response to the new generation of Dreadnought battleships Germany was building, during the naval arms race leading up to World War I. Due to the urgency of the times, the normally slow and cautious prototype and testing stages of a new gun's development were bypassed, and it was ordered straight from the drawing board. Despite its hurried development process, the gun met all expectations and was a competitive battleship main armament throughout both World ...

Transit Telescope
In astronomy, a transit instrument is a small telescope with extremely precisely graduated mount used for the precise observation of star positions. They were previously widely used in astronomical observatories and naval observatories to measure star positions in order to compile nautical almanacs for use by mariners for celestial navigation, and observe star transits to set extremely accurate clocks ( astronomical regulators) which were used to set marine chronometers carried on ships to determine longitude, and as primary time standards before atomic clocks. The instruments can be divided into three groups: meridian, zenith, and universal instruments. Types Meridian instruments For observation of star transits in the exact direction of South or North: * Meridian circles, Mural quadrants etc. * Passage instruments (transportable, also for prime vertical transits) Zenith instruments * Zenith telescope * Photozenith tube (PZT) * zenith cameras * Danjon astrolabe, Ze ...

Peak District
The Peak District is an Highland, upland area in England at the southern end of the Pennines. Mostly in Derbyshire, it extends into Cheshire, Greater Manchester, Staffordshire, West Yorkshire and South Yorkshire. It includes the Dark Peak, where moorland is found and the geology is dominated by gritstone, and the White Peak, a limestone area with valleys and gorges. The Dark Peak forms an arc on the north, east and west sides; the White Peak covers central and southern tracts. The historic Peak District extends beyond the National Park, which excludes major towns, quarries and industrial areas. It became the first of the national parks of England and Wales in 1951. Nearby Manchester, Stoke-on-Trent, Derby and Sheffield send millions of visitors – some 20 million live within an hour's ride. Inhabited from the Mesolithic era, it shows evidence of the Neolithic, Bronze Age, Bronze and Iron Ages. Settled by the Roman Britain, Romans and Anglo-Saxons, it remained largely agricultur ...
