The town name is seen as 'Darby' or 'Darbye' on early modern maps, such as that of Speed (1610).
Modern research into the history and archaeology of Derby has shown that the Vikings and Anglo-Saxons probably co-existed, occupying two areas of land surrounded by water. The Anglo-Saxon Chronicle (c. 900) says that "Derby is divided by water". These areas of land were known as Norþworþig and Deoraby, and were at the "Irongate" (north) side of Derby.
In World War I, Derby was targeted by German Zeppelin air bombers. They killed five people in a 1916 raid on the town.
All Saints Church was designated as a cathedral in 1927. That showed that the town was ready for city status.
In the 1920s and 1930s, slums were cleared out and people were moved to new council estates in the suburbs. There were also houses for sale there. Rehousing, council house building and private housing developments continued on a large scale for some 30 years after the end of World War II in 1945.
Derby became a high profile town internationally in sport following the appointment of Brian Clough as manager of Derby County F.C. in 1967. Promotion to the Football League First Division was achieved in 1969, and County won of the English league three years later. Following the Clough's resignation in 1973, his successor guided County to another league title in 1975, but this is the club's last major trophy to date; relegation followed in 1980 and top flight status was not regained until 1987, since when Derby have spent a total of 10 seasons (across two spells) in the top flight. The club moved from its century-old Baseball Ground in 1997 to the new Pride Park Stadium.
Derby was awarded city status on 7 June 1977 by Queen Elizabeth II. Until then, Derby had been one of the few towns in England with a cathedral but not city status.
Despite its strategic industries (rail and aero-engine), Derby suffered comparatively little damage in both world wars (contrast Bristol and Filton). This may in part have been due to the jamming of the German radio-beam navigations systems (X-Verfahren and Knickebein), camouflage and decoy techniques ('Starfish sites') were built, mainly south of the town, e.g. out in fields near Foremark.
Derby has several sports clubs.
Derby's main football club is Derby County who've won the FA Cup and the Football League. There are also three senior non-league football clubs based in the city. Derby also had a short lived baseball team, which played at Derby's former ground.
Arthur Keily the marathon runner and Olympian was born in Derbyshire in 1921 and has lived his whole life in Derby. In Rome in 1960 he broke the English Olympic record, recording a time of 2hours 27mins.
Derby has the first public park in the country to have an arboretum, which is south of the city centre. The arboretum was set up by the philanthropic landowner and industrialist Joseph Strutt in 1840. The arboretum's website states that the arboretum's design was the inspiration for the vision of great urban parks in the USA, notably Central Park in New York City.
There are four museums: Derby Museum and Art Gallery; Pickford's House Museum; The Silk Mill and The Royal Crown Derby Museum.
Stereo
Stereophonic sound, also simply called stereo, is the reproduction of sound using two or more audio loudspeakers. This creates a pleasant and natural sound heard from various directions, as in natural hearing.
The word "stereophonic" comes from Greek "stereos" = "solid" and "phōnē" = "sound". It was coined by Western Electric.
In popular usage, stereo usually means two-channel sound recording and sound reproduction using data from two speakers. The electronic device for playing back stereo sound is often called "a stereo".
Ely, Cambridgeshire
Ely (; , rhyming with "freely") is a cathedral city in the East Cambridgeshire district of Cambridgeshire in the east of England and north north-east of Cambridge.
Ely has been called a city for a long time because it has a cathedral. However, the Royal Charter making it a city was only issued in 1974. Ely's population was 15,102 in 2001. This means Ely is the third smallest city in England. Only after Wells in Somerset and the City of London which are smaller.
The University of Cambridge rowing team has a boathouse on the bank of the river and train there for the annual Boat Race against the University of Oxford.
The 1944 Boat Race was raced on the River Great Ouse near Ely, the only time it has not been held on the River Thames. The race was won by Oxford despite Cambridge being ahead early in the contest.
Ely is built on an clay which is one of the highest points in the Fens. This is very different to the West of Cambridgeshire which is made up of limestone. The river Great Ouse runs through the city, and is one of the longest rivers in the UK with many others flowing into it. The drainage area of the rivers that form the Great Ouse is around 6000 square miles (16,000 square kilometres). This is five times larger than the Fens itself The landscape was a large marsh until the 18th century, when much of the Fens was drained, making Ely no longer an island. Because of this, the ground around the city is very fertile and most of the region is used for farming. The marshes also had many different animals in them such as the Eel, which the city is named after.
Cambridgeshire is one of the driest counties in Britain. It is protected from coastal wind from the east. It gets an average of 24 inches (600mm) of rain per year. Because of this, Cambridgeshire is warm in summer and cold and frosty in winter.
Tube sound
Tube sound (or valve sound) is the sound produced by a vacuum tube-based audio amplifier. All amplifiers distort to some degree; some audiophiles prefer the sound produced by tube amplifiers. The reasons for the difference in sound between tube and solid state electronic devices is a continuing debate among audiophiles.

Sound recording and reproduction
Sound recording and reproduction is the storage of sound and playing it back so that a person can hear the same sound more than once. It is a process wherein sound waves are captured by a machine. The machine converts the waves into electrical signals or digital data, that are then stored on recording media (such as gramophone records, cassette tapes, compact discs or computer hard drives). The sound can then be played back by reversing the process.
Most recordings are of music, people speaking or singing, and sound effects. They are usually used for entertainment (fun), or for scientific and historical reasons.
Sound is recorded onto a medium by different methods. The ways that recordings are made have changed a lot since sound was first recorded.
