South East England is one of the nine official regions of England that are in the top level category for statistical purposes. It consists of the nine counties of Berkshire, Buckinghamshire, East Sussex, Hampshire, the Isle of Wight, Kent, Oxfordshire, Surrey and West Sussex. South East England is the third-largest region of England, with a land area of km2, and is also the most populous with a total population of in .

South East England contains eight legally chartered cities: Brighton and Hove, Canterbury, Chichester, Milton Keynes, Oxford, Portsmouth, Southampton and Winchester. Officially it does not include London, which is a separate region. The geographical term for "South East England" may differ from the official definition of the region; for example, London, Bedfordshire, Hertfordshire and Essex are sometimes colloquially referred to as being in the south east of England. This article only considers the South East as being the official statistical region.

In medieval times, South East England included much of the Kingdom of Wessex, which was the precursor to the modern state of England. Winchester was the capital of England after unification of the various states, including the kingdoms of Kent, Sussex and Mercia. Winchester stopped being the administrative capital of England some time in the 13th century as its influence waned while the City of London dominated commerce. The last monarch to be crowned at Winchester was Richard II in 1377, although the last monarch to be crowned by the Bishop of Winchester was Queen Mary I in 1553.

Today, the region's close proximity to London has led to South East England becoming a prosperous economic hub with the largest economy of any region in the UK, after London. The region is home to Gatwick Airport (the UK's second busiest airport). The coastline along the English Channel provides numerous ferry crossings to mainland Europe. South East England is also known for its countryside, which includes two national parks: the New Forest and the South Downs, as well as the North Downs, the Chiltern Hills and part of the Cotswolds. The River Thames flows through the region and its basin is known as the Thames Valley.

It is also the location of a number of internationally known places of interest, such as HMS Victory in Portsmouth, Cliveden in Buckinghamshire, Thorpe Park and RHS Wisley in Surrey, Blenheim Palace in Oxfordshire, Windsor Castle in Berkshire, Leeds Castle, the White Cliffs of Dover and Canterbury Cathedral in Kent, Brighton Palace Pier, and Hammerwood Park in East Sussex, and Wakehurst Place in West Sussex. The region has many universities; the University of Oxford is the oldest in the English-speaking world, and ranked among the best in the world.

South East England is host to various sporting events, including the annual Henley Royal Regatta, Royal Ascot and The Derby, and sporting venues include Wentworth Golf Club and Brands Hatch. Some of the events of the 2012 Summer Olympics were held in the south east, including the rowing at Eton Dorney and part of the cycling road race in the Surrey Hills.

History

The Meonhill Vineyard, near Old Winchester Hill in east Hampshire on the South Downs south of West Meon on the A32, is an example of a site where the Romano-British grew Roman grapes.

Second World War

Much of the Battle of Britain was fought in this region, especially in Kent. RAF Bomber Command was based at High Wycombe. RAF Medmenham at Danesfield House, west of Marlow in Buckinghamshire, was important for aerial reconnaissance. Operation Corona, based at RAF Kingsdown (at West Kingsdown next to Brands Hatch in Kent, between the A20 and M20), was implemented to confuse German night fighters with native German-speakers, and coordinated by the RAF Y service.

Bletchley Park in north Buckinghamshire was the principal Allied centre for codebreaking. The Colossus computer, arguably the world's first, began working on Lorentz codes on 5 February 1944, with Colossus 2 working from June 1944. The site was chosen, among other reasons, because it is at the junction of the Varsity Line (between Oxford and Cambridge) and the West Coast Main Line. The Harwell computer (Dekatron), now at the National Museum of Computing at Bletchley, was built in 1949 and is believed to be the oldest working digital computer in the world.

Scientific heritage

John Wallis of Kent introduced the symbol for infinity and the standard notation for powers of numbers in 1656. Thomas Bayes was an important statistician from Tunbridge Wells; his theorem (of probability theory) is used for spam filters and Google's search.

Sir David N. Payne at the University of Southampton's Optoelectronics Research Centre invented the erbium-doped fibre amplifier, a type of optical amplifier, in the mid-1980s, which became essential for the internet. Henry Moseley at Oxford in 1913 discovered his Moseley's law of X-ray spectra of chemical elements that enabled him to be the first to assign the correct atomic number to elements in periodic table; he did not receive any Nobel Prize as it is not awarded posthumously (he was killed in 1915 at Gallipoli with the Royal Engineers). Carbon fibre was invented in 1963 at the RAE in Farnborough by a team led by William Watt. The Apollo LCG space-suit cooling system originated mostly from work done at RAE Farnborough in the early 1960s.

Donald Watts Davies invented packet switching in the late 1960s at the National Physical Laboratory in Teddington. Packet-switching was taken up by the Americans to form the ARPANET, the precursor to the Internet.

Surrey's Alec Reeves invented pulse-code modulation (PCM) in 1937 (at ITT's research laboratories in Paris), the standard for digital audio recordings.

Sir John Herschel, son of the astronomer, from Kent, invented the term photography in 1839, meaning light writing.

and discovered the first photographic fixer, sodium thiosulphate, known as hypo, also in 1839.

GLEEP was Britain's first nuclear reactor, in August 1947 at the Atomic Energy Research Establishment (AERE) at Harwell, it would stay operational until 1990.

William Harvey of Folkestone, in Kent, discovered the circulation of blood. The Lilly Research Centre in Windlesham, Berkshire, part of Eli Lilly, developed Olanzapine in 1996 (for bipolar disorder, selling around $5bn worldwide annually). Beecham Research Laboratories at Brockham Park in 1959 discovered meticillin (or methicillin), the first semi-synthetic penicillin (beta-lactamase stable), deriving from their discovery in 1958 of 6-APA, the core constituent; the team, led by Prof George Rolinson, won the Mullard Award in 1971. Bipyridine compounds (Paraquat-Gramoxone and Diquat) were discovered for herbicide use in 1954 by William Boon at ICI's Plant Protection division at Jealott's Hill, being released onto the market in 1958. AZT/Retrovir (zidovudine) was first manufactured by Wellcome in 1987 in Kent; they also introduced Zovirax (aciclovir), and the naturally occurring digoxin, a cardiac glycoside. After a plane crashed near his house in Oxford in 1940, Sir Peter Medawar helped the injured pilot, and in the process discovered homograft rejection, leading to organ transplantation using azathioprine. Viagra (Sildenafil) was synthesized at Pfizer in Sandwich, Kent.

Industrial heritage

Transport and communications

Sir Francis Pettit Smith of Kent invented the screw propeller.

On 3 May 1830 the world's first passenger train service, the Canterbury and Whitstable Railway (6 miles or 10 km) began. It was built by George Stephenson and hauled by the locomotive Invicta. It introduced the world's first railway season ticket in 1834.

Maidenhead Railway Bridge, known for its flat arch, was built in 1839 with 39-metre spans.

The Military Vehicles and Engineering Establishment, in Chertsey, developed Chobham armour.

On 12 April 1903, the world's first bus service was by Eastbourne Buses from Eastbourne railway station to Meads.

The world's first submarine telephone cable was laid between England and France in 1891 by HMTS Monarch, enabling London-Paris calls from April 1891. On 3 December 1992, Neil Papworth of Reading, an engineer from Sema Group Telecoms at Vodafone in Newbury, sent the world's first text message from his computer to an Orbitel 901 handset of Richard Jarvis, Vodafone's technical director.

The first public automatic telephone exchange in the UK was at Epsom telephone exchange from 18 May 1912. It was introduced as standard across the UK's 6,700 telephone exchanges in 1922, lasting for around 70 years; it could handle up to 500 lines. It used the Strowger design and was made by Automatic Telephone Manufacturing Company of Liverpool. The world's first automatic telephone exchange had opened in La Porte, Indiana in November 1892.

UK-Belgium 5, laid in 1986 from Kent, was the world's first optical fibre submarine cable, and is 36 miles long.

ThrustSSC, the fastest car in the world in 1997, was built in Aldingbourne, West Sussex, by G-Force Engineering, designed by Ron Ayers, with further work done by the Defence Evaluation and Research Agency at Farnborough.

The BritNed 1000MW power-supply submarine cable from Isle of Grain to Rotterdam, was built in 2009. The HVDC Cross-Channel (2000MW) submarine cable was built in 1986. This is the world's highest-capacity submarine HVDC cable; it goes from France and lands near Folkestone, with the large transformer station (built by GEC) squeezed between the CTRL and the M20 in Aldington and Smeeth, made of eight 270 kV cables.

Aviation

On 16 October 1908 the British Army Aeroplane No 1, flown by the American Samuel Franklin Cody, was the first aircraft flown in the UK, at Farnborough; on 14 May 1909 he flew it for more than a mile. On 13 August 1909, his wife was the first woman in the UK to fly in a plane, also at Farnborough.

The first human airborne ejection seat firing took place on 24 July 1946 over Chalgrove Airfield, Oxfordshire, in a Meteor, piloted by Bernard Lynch; the first dummy ejection had been 10 May 1945 over RAF Oakley in west Buckinghamshire (today near the M40); on 13 March 1962, the first in-flight rocket-powered ejection took place by Peter Howard, an RAF doctor based at Farnborough's Institute of Aviation Medicine in Meteor WA364 at 250 ft over Chalgrove, with the rocket giving a maximum force of 16G. The Miles M.52, designed at Woodley Aerodrome in Berkshire by Miles Aircraft, was an advanced design of aircraft which had the innovation of the flying tail or all-moving tail also known as a stabilator; this would solve the problem of stability and aircraft control at supersonic speeds, and its design was taken wholesale into the American Bell X-1, the first supersonic aircraft.

The first Harrier aircraft XV738 flew on 28 December 1967; this was the first aircraft of the RAF to have a head-up display avionics system. The first two-seat Harrier XW174 flew on 24 April 1969, later crashing at Larkhill in June 1969. The British Aerospace Sea Harrier XZ450 first flew on 20 August 1978; on 4 May 1982 this aircraft was hit by anti-aircraft fire at Goose Green, killing the pilot with 800 Naval Air Squadron from HMS Hermes; the aircraft had no radar warning receiver (RWR), due to testing the Sea Eagle, so could not detect the Skyguard radar had locked on to it. It was destroyed with the Oerlikon GDF (35mm) of GADA 601; it was the first Sea Harrier lost in the Falklands campaign.

Royston Instruments of Byfleet developed the world's first multi-channel flight data recorders in 1965.

Although the Comet is generally accepted as the world's first production-run jet airliner, the first jet airliner ever built (individual) was a Nene-powered Vickers VC.1 Viking on 6 April 1948 from Wisley Airfield; the world's first turboprop airliner would fly from there on 16 July 1948 by Mutt Summers. In 1939 at Cowes (Northwood) John Godeck invented the plan position indicator method of radar display as most commonly known ever since; the site became Plessey Radar in 1965, and currently is run by BAE Systems. Sperry Gyroscope in Bracknell produced the guidance systems for Britain's 1960s space rockets.

Other industries

The Wealden iron industry in the Weald was the site of the first blast furnace in Britain in 1491, and produced much of Britain's cast iron until the 1770s.

Portsmouth Block Mills were the site of the world's first metal machine tools, built for the manufacture of wooden pulleys, invented by Henry Maudslay, and the site of the world's first industrial assembly line in 1803.

South Foreland Lighthouse on 8 December 1858 was the world's first lighthouse with electric light, with the first type of industrial electrical generator made by Frederick Hale Holmes, from work he had carried out with Floris Nollet of Belgium, and 36 permanent magnets. By 1880, of the ten lighthouses with electric light, five were in the UK. From the lighthouse in 1899, the first international radio broadcast to France was made. Zénobe Gramme of Belgium made a much better design in 1870 with self-excitation of magnets, and the first modern dynamo. North Foreland Lighthouse was the UK's last-staffed lighthouse until 1998.

Portland cement was developed in Northfleet, Kent, by William Aspdin, son of Joseph Aspdin. The development was to heat the ingredients to around 1450 °C, producing clinker. Previously, temperatures were taken to only 800 °C, which was not enough. The first ever cement kiln is still in Northfleet today in a cardboard factory. In the late 1800s, the rotary kiln made the process much more efficient. Concrete, effectively human-made stone, is the most widespread human-made material. 5% of all carbon emissions worldwide are from concrete production.
