John Roger Arnold
John Arnold (1736 – 11 August 1799) was an English watchmaker and inventor. John Arnold was the first to design a watch that was both practical and accurate, and also brought the term "chronometer" into use in its modern sense, meaning a precision timekeeper. His technical advances enabled the quantity production of marine chronometers for use on board ships from around 1782. The basic design of these has remained, with a few modifications unchanged until the late twentieth century. His legacy includes, together with Abraham-Louis Breguet, as one of the inventors of the modern mechanical watch. One of his most important inventions, the overcoil balance spring is still used in most mechanical wristwatches. It was from around 1770 that Arnold developed the portable precision timekeeper, almost from the point where John Harrison ended his work in this field. But, compared to Harrison's complicated and expensive watch, Arnold's basic design was simple whilst consistently accurate ...

Bodmin
Bodmin () is a town and civil parish in Cornwall, England, United Kingdom. It is situated south-west of Bodmin Moor.

Board Of Longitude
The Commissioners for the Discovery of the Longitude at Sea, or more popularly Board of Longitude, was a British government body formed in 1714 to administer a scheme of prizes intended to encourage innovators to solve the problem of finding longitude at sea. Origins Navigators and scientists had been working on the problem of not knowing a ship's longitude. The establishment of the Board of Longitude was motivated by this problem and by the 1707 grounding of four ships of Vice-Admiral Sir Cloudesley Shovell's fleet off the Isles of Scilly, resulting in heavy loss of life. Established by Queen Anne the Longitude Act 1714 named 24 Commissioners of Longitude, key figures from politics, the Navy, astronomy and mathematics. However, the Board did not meet until at least 1737 when interest grew in John Harrison's marine timekeeper. The Board administered prizes for those who could demonstrate a working device or method. The main longitude prizes were: *£10,000 for a method that co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nevil Maskelyne
Nevil Maskelyne (; 6 October 1732 – 9 February 1811) was the fifth British Astronomer Royal. He held the office from 1765 to 1811. He was the first person to scientifically measure the mass of the planet Earth. He created the ''British Nautical Almanac and Astronomical Ephemeris for the Meridian of the Royal Observatory at Greenwich'' using Johann Tobias Mayer's corrections for Euler's ''Lunar Theory'' tables. Biography Maskelyne was born in London, the third son of Edmund Maskelyne of Purton in Wiltshire, and his wife, Elizabeth Booth. Maskelyne's father died when he was 12, leaving the family in reduced circumstances. Maskelyne attended Westminster School and was still a pupil there when his mother died in 1748. His interest in astronomy had begun while at Westminster School, shortly after the eclipse of 14 July 1748. Maskelyne entered St Catharine's College, Cambridge in 1749, graduating as seventh wrangler in 1754. Ordained as a minister in 1755, he became a fellow o ...

Astronomer Royal
Astronomer Royal is a senior post in the Royal Households of the United Kingdom. There are two officers, the senior being the Astronomer Royal dating from 22 June 1675; the junior is the Astronomer Royal for Scotland dating from 1834.

The Astronomer Royal was director of the Royal Observatory Greenwich from the establishment of the post in 1675 until 1972. The Astronomer Royal became an honorary title in 1972 without executive responsibilities and a separate post of Director of the Royal Greenwich Observatory was created to manage the institution. The Astronomer Royal today receives a stipend of 100 GBP per year and is a member of the Royal Household, under the general authority of the Lord Chamberlain. After the separation of the two offices, the position of Astronomer Royal has been largely honorary, though the ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

La Chaux-de-Fonds
La Chaux-de-Fonds () is a Swiss city in the canton of Neuchâtel. It is located in the Jura mountains at an altitude of 1000 m, a few kilometers south of the French border. After Geneva, Lausanne and Fribourg, it is the fourth largest city located in the Romandie, the French-speaking part of the country, with a population () of . The city was founded in 1656. Its growth and prosperity is mainly bound up with the watch-making industry. It is the most important centre of the watch-making industry in the area known as the Watch Valley. Partially destroyed by a fire in 1794, La Chaux-de-Fonds was rebuilt following a grid street plan, which was and is still original among Swiss cities, the only exception being the easternmost section of the city, which was spared by the fire. This creates an interesting and obvious transition from the old section to the newer section. The roads in the original section are very narrow and winding, which then open up to the grid pattern near the town ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strand, London
Strand (or the Strand) is a major thoroughfare in the City of Westminster, Central London. It runs just over from Trafalgar Square eastwards to Temple Bar, where the road becomes Fleet Street in the City of London, and is part of the A4, a main road running west from inner London. The road's name comes from the Old English ''strond'', meaning the edge of a river, as it historically ran alongside the north bank of the River Thames. The street was much identified with the British upper classes between the 12th and 17th centuries, with many historically important mansions being built between the Strand and the river. These included Essex House, Arundel House, Somerset House, Savoy Palace, Durham House and Cecil House. The aristocracy moved to the West End during the 17th century, and the Strand became known for its coffee shops, restaurants and taverns. The street was a centre point for theatre and music hall during the 19th century, and several venues remain on the St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hertfordshire
Hertfordshire ( or ; often abbreviated Herts) is one of the home counties in southern England. It borders Bedfordshire and Cambridgeshire to the north, Essex to the east, Greater London to the south, and Buckinghamshire to the west.

Holland
Holland is a geographical regionG. Geerts & H. Heestermans, 1981, ''Groot Woordenboek der Nederlandse Taal. Deel I'', Van Dale Lexicografie, Utrecht, p 1105 and former province on the western coast of the Netherlands. From the 10th to the 16th century, Holland proper was a unified political region within the Holy Roman Empire as a county ruled by the counts of Holland. By the 17th century, the province of Holland had risen to become a maritime and economic power, dominating the other provinces of the newly independent Dutch Republic. The area of the former County of Holland roughly coincides with the two current Dutch provinces of North Holland and South Holland into which it was divided, and which together include the Netherlands' three largest cities: the capital city (Amsterdam), the home of Europe's largest port (Rotterdam), and the seat of government (The Hague). Holland has a population of 6,583,534 as of November 2019, and a population density of 1203/km2. The name '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
