9000-550: The city, which is also the home of two professional football teams: Notts County , recognised as the world's oldest professional league club, and Nottingham Forest , famously two-time winners of the UEFA European Cup under Brian Clough and Peter Taylor in 1979 and 1980 . The city has professional rugby, ice hockey and cricket teams; it also hosts the Aegon Nottingham Open , an international tennis tournament on
9125-461: The city. Electric trams were introduced to the city in 1901; they served the city for 35 years until 1936. Trams were reintroduced after 68 years when a new network opened in 2004. In the sporting world, Nottingham is home to the world's oldest professional football club, Notts County , which was formed in 1862. The town's other football club, Nottingham Forest , had a period of success between 1977 and 1993 under manager Brian Clough , winning
9250-554: The concept of a programmable computer. Considered the " father of the computer ", he conceptualized and invented the first mechanical computer in the early 19th century. After working on his difference engine he announced his invention in 1822, in a paper to the Royal Astronomical Society , titled "Note on the application of machinery to the computation of astronomical and mathematical tables". He also designed to aid in navigational calculations, in 1833 he realized that
9375-627: The core of general-purpose devices such as personal computers and mobile devices such as smartphones . Computers power the Internet , which links billions of computers and users. Early computers were meant to be used only for calculations. Simple manual instruments like the abacus have aided people in doing calculations since ancient times. Early in the Industrial Revolution , some mechanical devices were built to automate long, tedious tasks, such as guiding patterns for looms . More sophisticated electrical machines did specialized analog calculations in
9500-552: The county town of Nottinghamshire even though the county hall is in the neighbouring town of West Bridgford where the county council is based. The city also has a Lord Mayor who is selected by city councillors from among themselves. The position is largely ceremonial but the Lord Mayor also acts as Chair of Full Council meetings. The City of Nottingham's boundaries are tightly drawn and exclude several suburbs and towns that are usually considered part of Greater Nottingham . Unlike
9625-493: The data signals do not have to travel long distances. Since ENIAC in 1945, computers have advanced enormously, with modern SoCs (such as the Snapdragon 865) being the size of a coin while also being hundreds of thousands of times more powerful than ENIAC, integrating billions of transistors, and consuming only a few watts of power. The first mobile computers were heavy and ran from mains power. The 50 lb (23 kg) IBM 5100
9750-507: The decision of the British Government to cease funding. Babbage's failure to complete the analytical engine can be chiefly attributed to political and financial difficulties as well as his desire to develop an increasingly sophisticated computer and to move ahead faster than anyone else could follow. Nevertheless, his son, Henry Babbage , completed a simplified version of the analytical engine's computing unit (the mill ) in 1888. He gave
9875-419: The decline of traditional industries. Once the principal engine of Nottingham's growth, the Lace Market powered a hosiery industry with 25,000 mostly female workers at its peak in the 1890s. Lace declined as technology changed and the working population fell below 5,000 in the 1970s with many of the factories becoming derelict and the area falling into decline. The Lace Market has undergone a renaissance and become
10000-435: The development of new public and private housing estates and new urban centres, which have engulfed former rural villages such as Bilborough, Wollaton, Gedling and Bramcote. South of the river there has also been expansion with new areas such as Edwalton and West Bridgford, adding to Nottingham's urban sprawl . Although this growth slowed towards the end of the century, the modern pressures for more affordable and council housing
10125-454: The direction of John Mauchly and J. Presper Eckert at the University of Pennsylvania, ENIAC's development and construction lasted from 1943 to full operation at the end of 1945. The machine was huge, weighing 30 tons, using 200 kilowatts of electric power and contained over 18,000 vacuum tubes, 1,500 relays, and hundreds of thousands of resistors, capacitors, and inductors. The principle of
10250-479: The doll is at the Musée d'Art et d'Histoire of Neuchâtel , Switzerland , and still operates. In 1831–1835, mathematician and engineer Giovanni Plana devised a Perpetual Calendar machine , which through a system of pulleys and cylinders could predict the perpetual calendar for every year from 0 CE (that is, 1 BCE) to 4000 CE, keeping track of leap years and varying day length. The tide-predicting machine invented by
10375-475: The early 11th century. The astrolabe was invented in the Hellenistic world in either the 1st or 2nd centuries BCE and is often attributed to Hipparchus . A combination of the planisphere and dioptra , the astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy . An astrolabe incorporating a mechanical calendar computer and gear -wheels
10500-399: The early 20th century. The first digital electronic calculating machines were developed during World War II , both electromechanical and using thermionic valves . The first semiconductor transistors in the late 1940s were followed by the silicon -based MOSFET (MOS transistor) and monolithic integrated circuit chip technologies in the late 1950s, leading to the microprocessor and
10625-473: The exact definition of the term "microprocessor", it is largely undisputed that the first single-chip microprocessor was the Intel 4004 , designed and realized by Federico Faggin with his silicon-gate MOS IC technology, along with Ted Hoff , Masatoshi Shima and Stanley Mazor at Intel . In the early 1970s, MOS IC technology enabled the integration of more than 10,000 transistors on a single chip. System on
10750-421: The filming location of Saturday Night and Sunday Morning , was demolished in 2003 to make way for the University of Nottingham Jubilee Campus 's expansion. In 2015, Nottingham was ranked in the top 10 UK cities for job growth (from 2004 to 2013), in the public and private sectors. and in the same year, it was revealed that more new companies were started in Nottingham in 2014–15 than in any other UK city, with
10875-503: The first Colossus. After a functional test in December 1943, Colossus was shipped to Bletchley Park, where it was delivered on 18 January 1944 and attacked its first message on 5 February. Colossus was the world's first electronic digital programmable computer. It used a large number of valves (vacuum tubes). It had paper-tape input and was capable of being configured to perform a variety of boolean logical operations on its data, but it
11000-725: The first attested use of computer in the 1640s, meaning 'one who calculates'; this is an "agent noun from compute (v.)". The Online Etymology Dictionary states that the use of the term to mean " 'calculating machine' (of any type) is from 1897." The Online Etymology Dictionary indicates that the "modern use" of the term, to mean 'programmable digital electronic computer' dates from "1945 under this name; [in a] theoretical [sense] from 1937, as Turing machine ". The name has remained, although modern computers are capable of many higher-level functions. Devices have been used to aid computation for thousands of years, mostly using one-to-one correspondence with fingers . The earliest counting device
11125-409: The form of conditional branching and loops , and integrated memory , making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete . The machine was about a century ahead of its time. All the parts for his machine had to be made by hand – this was a major problem for a device with thousands of parts. Eventually, the project was dissolved with
11250-494: The heart of the world's lace industry during the days of the British Empire , it is full of impressive examples of 19th-century industrial architecture and thus is a protected heritage area. It was never a market in the sense of having stalls, but there were salesrooms and warehouses for storing, displaying and selling the lace. Most of the area is typical Victorian , with densely packed 4–7 storey red-brick building lined streets. Iron railings, old gas lamps and red phone boxes
11375-515: The highest concentration of higher education providers in the East Midlands . A community existed in what is now Nottingham's city centre before the Anglo-Saxon settlement of Britain . This community was recorded under the name Tigguo Cobauc ( Brythonic : Tig Guocobauc ) by the ninth century cleric Asser , in his work The Life of King Alfred . This original name survives as Y Tŷ Ogofog ,
11500-462: The integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958. In his patent application of 6 February 1959, Kilby described his new device as "a body of semiconductor material ... wherein all the components of the electronic circuit are completely integrated". However, Kilby's invention was a hybrid integrated circuit (hybrid IC), rather than
11625-411: The integration. In 1876, Sir William Thomson had already discussed the possible construction of such calculators, but he had been stymied by the limited output torque of the ball-and-disk integrators . In a differential analyzer, the output of one integrator drove the input of the next integrator, or a graphing output. The torque amplifier was the advance that allowed these machines to work. Starting in
11750-553: The late 18th century was the German traveller C. P. Moritz , who wrote in 1782, "Of all the towns I have seen outside London, Nottingham is the loveliest and neatest. Everything had a modern look, and a large space in the centre was hardly less handsome than a London square. A charming footpath leads over the fields to the highway, where a bridge spans the Trent. … Nottingham … with its high houses, red roofs and church steeples, looks excellent from
11875-480: The late medieval period Nottingham alabasters were exported as far afield as Iceland, and may be one reason why a small number of Icelandic immigrants lived in Nottingham during the 15th century. The town became a county corporate in 1449 giving it effective self-government, in the words of the charter, "for eternity". The Castle and Shire Hall were expressly excluded and remained as detached Parishes of Nottinghamshire . One of those highly impressed by Nottingham in
12000-479: The legends of Robin Hood , Nottingham Castle is the scene of the final showdown between the Sheriff and the hero outlaw. King John of England (formerly Prince John) visited Nottingham in 1199 and 1202. Later King Henry III of England held a court in Nottingham. By the 15th century Nottingham had established itself as a centre of a thriving export trade in religious sculpture made from Nottingham alabaster . During
12125-569: The machine did make use of valves to generate its 125 kHz clock waveforms and in the circuitry to read and write on its magnetic drum memory , so it was not the first completely transistorized computer. That distinction goes to the Harwell CADET of 1955, built by the electronics division of the Atomic Energy Research Establishment at Harwell . The metal–oxide–silicon field-effect transistor (MOSFET), also known as
12250-452: The modern computer was proposed by Alan Turing in his seminal 1936 paper, On Computable Numbers . Turing proposed a simple device that he called "Universal Computing machine" and that is now known as a universal Turing machine . He proved that such a machine is capable of computing anything that is computable by executing instructions (program) stored on tape, allowing the machine to be programmable. The fundamental concept of Turing's design
12375-403: The more famous Sir William Thomson. The art of mechanical analog computing reached its zenith with the differential analyzer , built by H. L. Hazen and Vannevar Bush at MIT starting in 1927. This built on the mechanical integrators of James Thomson and the torque amplifiers invented by H. W. Nieman. A dozen of these devices were built before their obsolescence became obvious. By the 1950s,
12500-571: The parishes of St Mary, St Nicholas and St Peter. It was expanded in 1877 by adding the parishes of Basford , Brewhouse Yard, Bulwell , Radford , Sneinton , Standard Hill, and parts of the parishes of West Bridgford , Carlton , Wilford (North Wilford). In 1889 Nottingham became a county borough under the Local Government Act 1888 . City status was awarded as part of the Diamond Jubilee celebrations of Queen Victoria, being signified in
12625-577: The parliamentary constituency boundaries do not align with the boundaries of the council districts of which they share their name. Nottingham is situated on an area of low hills along the lower valley of the River Trent , and is surrounded by the Sherwood Forest in the north, the Nottinghamshire, Derbyshire and Yorkshire Coalfield in the west, and the Trent and Belvoir Vales in the east and south. Within
12750-559: The perimeter of the town. A short length of the wall survives, and is visible at the northern end of Maid Marian Way, and is protected as a Scheduled Monument. On the return of King Richard the Lionheart from the Crusades in 1194, the castle was occupied by supporters of Prince John , including the Sheriff of Nottingham . It was besieged by Richard and, after a sharp conflict, was captured. In
12875-486: The practical use of MOS transistors as memory cell storage elements, leading to the development of MOS semiconductor memory , which replaced earlier magnetic-core memory in computers. The MOSFET led to the microcomputer revolution , and became the driving force behind the computer revolution . The MOSFET is the most widely used transistor in computers, and is the fundamental building block of digital electronics . The next great advance in computing power came with
13000-482: The results of operations to be saved and retrieved. It was not until the mid-20th century that the word acquired its modern definition; according to the Oxford English Dictionary , the first known use of the word computer was in a different sense, in a 1613 book called The Yong Mans Gleanings by the English writer Richard Brathwait : "I haue [ sic ] read the truest computer of Times, and
13125-575: The same time that digital calculation replaced analog. The engineer Tommy Flowers , working at the Post Office Research Station in London in the 1930s, began to explore the possible use of electronics for the telephone exchange . Experimental equipment that he built in 1934 went into operation five years later, converting a portion of the telephone exchange network into an electronic data processing system, using thousands of vacuum tubes . In
13250-478: The stored-program computer was laid out by Alan Turing in his 1936 paper. In 1945, Turing joined the National Physical Laboratory and began work on developing an electronic stored-program digital computer. His 1945 report "Proposed Electronic Calculator" was the first specification for such a device. John von Neumann at the University of Pennsylvania also circulated his First Draft of a Report on
13375-443: The success of digital electronic computers had spelled the end for most analog computing machines, but analog computers remained in use during the 1950s in some specialized applications such as education ( slide rule ) and aircraft ( control systems ). Claude Shannon 's 1937 master's thesis laid the foundations of digital computing, with his insight of applying Boolean algebra to the analysis and synthesis of switching circuits being
13500-446: The target sectors of their economic development strategy would include low-carbon technologies; digital media ; life sciences ; financial and business services; and retail and leisure. The city formerly had a major bicycle manufacturing industry sector. Raleigh Bicycle Company was established in 1886 and Sturmey-Archer , the developer of three-speed hub gears, was also founded in the city. Raleigh's factory on Triumph Road, famous as
13625-477: The town of Bingham . Nottingham has three UK parliamentary constituency seats within its boundaries. Nottingham North has been represented since 2017 by Labour Member of Parliament (MP) Alex Norris , Nottingham East since 2019 by Labour MP Nadia Whittome and Nottingham South since 2010 by Labour MP Lilian Greenwood . Each of the outer districts (Broxtowe, Ashfield, Gedling and Rushcliffe) are also parliamentary constituencies in their own right although

13875-406: Was a 16-transistor chip built by Fred Heiman and Steven Hofstein at RCA in 1962. General Microelectronics later introduced the first commercial MOS IC in 1964, developed by Robert Norman. Following the development of the self-aligned gate (silicon-gate) MOS transistor by Robert Kerwin, Donald Klein and John Sarace at Bell Labs in 1967, the first silicon-gate MOS IC with self-aligned gates
14000-614: Was an early example. Later portables such as the Osborne 1 and Compaq Portable were considerably lighter but still needed to be plugged in. The first laptops, such as the Grid Compass , removed this requirement by incorporating batteries – and with the continued miniaturization of computing resources and advancements in portable battery life, portable computers grew in popularity in the 2000s. The same developments allowed manufacturers to integrate computing resources into cellular mobile phones by
14125-461: Was built in 1865. King and Queen Streets are home to striking Victorian buildings designed by such architects as Alfred Waterhouse and Watson Fothergill . The Canal-side to the south of the city is adjacent to Nottingham railway station and home to multiple repurposed (as bars and restaurants) 19th-century industrial buildings. The eastern third of the city contains Hockley Village , with specialist and independent shops. The Victoria Centre
14250-530: Was built with 2000 relays , implementing a 22 bit word length that operated at a clock frequency of about 5–10 Hz . Program code was supplied on punched film while data could be stored in 64 words of memory or supplied from the keyboard. It was quite similar to modern machines in some respects, pioneering numerous advances such as floating-point numbers . Rather than the harder-to-implement decimal system (used in Charles Babbage 's earlier design), using
14375-450: Was delivered to the University of Manchester in February 1951. At least seven of these later machines were delivered between 1953 and 1957, one of them to Shell labs in Amsterdam . In October 1947 the directors of British catering company J. Lyons & Company decided to take an active role in promoting the commercial development of computers. Lyons's LEO I computer, modelled closely on
14500-443: Was developed by Federico Faggin at Fairchild Semiconductor in 1968. The MOSFET has since become the most critical device component in modern ICs. The development of the MOS integrated circuit led to the invention of the microprocessor , and heralded an explosion in the commercial and personal use of computers. While the subject of exactly which device was the first microprocessor is contentious, partly due to lack of agreement on
14625-825: Was developed in the late 16th century and found application in gunnery, surveying and navigation. The planimeter was a manual instrument to calculate the area of a closed figure by tracing over it with a mechanical linkage. The slide rule was invented around 1620–1630, by the English clergyman William Oughtred , shortly after the publication of the concept of the logarithm . It is a hand-operated analog computer for doing multiplication and division. As slide rule development progressed, added scales provided reciprocals, squares and square roots, cubes and cube roots, as well as transcendental functions such as logarithms and exponentials, circular and hyperbolic trigonometry and other functions . Slide rules with special scales are still used for quick performance of routine calculations, such as
14750-529: Was formed in 2017, by the amalgamation of Central College Nottingham and New College Nottingham (which had both previously formed from the merger of smaller FE colleges); and the Confetti Institute of Creative Technologies , owned by Nottingham Trent University, is a further education college that specialises in media. The city has dozens of sixth form colleges and academies, providing education and training for adults aged over sixteen. Nottingham also has
14875-449: Was invented by Abi Bakr of Isfahan , Persia in 1235. Abū Rayhān al-Bīrūnī invented the first mechanical geared lunisolar calendar astrolabe, an early fixed- wired knowledge processing machine with a gear train and gear-wheels, c. 1000 AD . The sector , a calculating instrument used for solving problems in proportion, trigonometry , multiplication and division, and for various functions, such as squares and cube roots,
15000-477: Was made of germanium . Noyce's monolithic IC was fabricated using the planar process , developed by his colleague Jean Hoerni in early 1959. In turn, the planar process was based on Carl Frosch and Lincoln Derick work on semiconductor surface passivation by silicon dioxide. Modern monolithic ICs are predominantly MOS ( metal–oxide–semiconductor ) integrated circuits, built from MOSFETs (MOS transistors). The earliest experimental MOS IC to be fabricated
15125-630: Was most likely a form of tally stick . Later record keeping aids throughout the Fertile Crescent included calculi (clay spheres, cones, etc.) which represented counts of items, likely livestock or grains, sealed in hollow unbaked clay containers. The use of counting rods is one example. The abacus was initially used for arithmetic tasks. The Roman abacus was developed from devices used in Babylonia as early as 2400 BCE. Since then, many other forms of reckoning boards or tables have been invented. In
15250-497: Was named one of the UK's six science cities in 2005 by the then Chancellor of the Exchequer Gordon Brown . Among the science-based industries within the city is BioCity . Founded as a joint venture between Nottingham Trent University and the University of Nottingham, it is the UK's biggest bioscience innovation and incubation centre, housing around 80 science-based companies. In 2010, Nottingham City Council announced that
15375-434: Was not Turing-complete. Nine Mk II Colossi were built (The Mk I was converted to a Mk II making ten machines in total). Colossus Mark I contained 1,500 thermionic valves (tubes), but Mark II with 2,400 valves, was both five times faster and simpler to operate than Mark I, greatly speeding the decoding process. The ENIAC (Electronic Numerical Integrator and Computer) was the first electronic programmable computer built in
15500-637: Was originally confined to the area today known as the Lace Market and was surrounded by a substantial defensive ditch and rampart, which fell out of use following the Norman Conquest and was filled by the time of the Domesday Book (1086). Following the Norman Conquest the Saxon settlement developed into the English Borough of Nottingham and housed a Town Hall and Law Courts. A settlement also developed around
15625-447: Was reported that Nottingham was one of a number of UK cities that broke WHO air pollution guidelines for the maximum concentration of small particulate matter; the pollution in part being caused by harmful wood-burning stoves. Nottingham is bounded by a green belt area, provisionally drawn up from the 1950s. Completely encircling the city, it extends for several miles into the surrounding districts, as well as towards Derby. Like most of
