John Harrison
John Harrison ( – 24 March 1776) was a self-educated English Carpentry, carpenter and clockmaker who invented the marine chronometer, a long-sought-after device for solving the History of longitude, problem of calculating longitude while at sea. Harrison's solution revolutionized navigation and greatly increased the safety of long-distance sea travel. The problem he solved was considered so important following the Scilly naval disaster of 1707 that the Parliament of Great Britain, British Parliament offered financial rewards of up to £20,000 (equivalent to £ in ) under the 1714 Longitude Act. In 1730, Harrison presented his first design, and worked over many years on improved designs, making several advances in time-keeping technology, finally turning to what were called sea watches. Harrison gained support from the Board of Longitude, Longitude Board in building and testing his designs. Toward the end of his life, he received recognition and a reward from Parliament. Harri ...

Longitude Rewards
The longitude rewards were the system of inducement prizes offered by the British government for a simple and practical method for the precise determination of a ship's longitude at sea. The rewards, established through an Act of Parliament (the Longitude Act) in 1714, were administered by the Board of Longitude. This was by no means the first reward to be offered to solve this problem. Philip II of Spain offered one in 1567, Philip III in 1598 offered 6,000 ducats and a pension, whilst the States General of the Netherlands offered 10,000 florins shortly after. In 1675 Robert Hooke wanted to apply for a £1,000 reward in England for his invention of a spring-regulated watch. However, these large sums were never won, though several people were awarded smaller amounts for significant achievements. Background: the longitude problem The measurement of longitude was a problem that came into sharp focus as people began making transoceanic voyages. Determining latitude was relativ ...

Scilly Naval Disaster Of 1707
The Scilly naval disaster of 1707 was the loss of four warships of a Royal Navy fleet off the Isles of Scilly in severe weather on 22 October 1707. Between 1,400 and 2,000 sailors lost their lives aboard the wrecked vessels, making the incident one of the worst maritime disasters in British naval history.The earliest reports of the disaster appeared in the ''Daily Courant'', and were rather brief. The account for 1 November 1707 read: "an Account, that Sir Cloudsly Shovel with about 20 Sail of Men of War coming from the Streights, having made an Observation the 21st, lay the 22d from 12 to about 6 in the Afternoon; but the Weather being very hazy and rainy and Night coming on dark, the Wind being S.S.W, they Stearing E by N, supposing they had the Channel open, were some of them upon the Rocks to the Westward of Scilly before they were aware, about 8 a Clock at Night. Of the Association not a Man was sav’d ... The Captain and 24 Men of the Firebrand Fire-Shop were saved, as were ...

Conducting
Conducting is the art of directing a musical performance, such as an orchestral or choral concert. It has been defined as "the art of directing the simultaneous performance of several players or singers by the use of gesture." The primary duties of the conductor are to interpret the score in a way which reflects the specific indications in that score, set the tempo, ensure correct entries by ensemble members, and "shape" the phrasing where appropriate. Conductors communicate with their musicians primarily through hand gestures, usually with the aid of a baton, and may use other gestures or signals such as eye contact. A conductor usually supplements their direction with verbal instructions to their musicians in rehearsal. The conductor typically stands on a raised podium with a large music stand for the full score, which contains the musical notation for all the instruments or voices. Since the mid-19th century, most conductors have not played an instrument when conducting, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Music
Music is generally defined as the art of arranging sound to create some combination of form, harmony, melody, rhythm or otherwise expressive content. Exact definitions of music vary considerably around the world, though it is an aspect of all human societies, a cultural universal. While scholars agree that music is defined by a few specific elements, there is no consensus on their precise definitions. The creation of music is commonly divided into musical composition, musical improvisation, and musical performance, though the topic itself extends into academic disciplines, criticism, philosophy, and psychology. Music may be performed or improvised using a vast range of instruments, including the human voice. In some musical contexts, a performance or composition may be to some extent improvised. For instance, in Hindustani classical music, the performer plays spontaneously while following a partially defined structure and using characteristic motifs. In modal jazz ...

Watch
A watch is a portable timepiece intended to be carried or worn by a person. It is designed to keep a consistent movement despite the motions caused by the person's activities. A wristwatch is designed to be worn around the wrist, attached by a watch strap or other type of bracelet, including metal bands, leather straps or any other kind of bracelet. A pocket watch is designed for a person to carry in a pocket, often attached to a chain. Watches were developed in the 17th century from spring-powered clocks, which appeared as early as the 14th century. During most of its history the watch was a mechanical device, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. These are called ''mechanical watches''. In the 1960s the electronic ''quartz watch'' was invented, which was powered by a battery and kept time with a vibrating quartz crystal. By the 1980s the quartz watch had taken over most of the market from the mechani ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Smallpox
Smallpox was an infectious disease caused by variola virus (often called smallpox virus) which belongs to the genus Orthopoxvirus. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making it the only human disease to be eradicated. The initial symptoms of the disease included fever and vomiting. This was followed by formation of ulcers in the mouth and a skin rash. Over a number of days, the skin rash turned into the characteristic fluid-filled blisters with a dent in the center. The bumps then scabbed over and fell off, leaving scars. The disease was spread between people or via contaminated objects. Prevention was achieved mainly through the smallpox vaccine. Once the disease had developed, certain antiviral medication may have helped. The risk of death was about 30%, with higher rates among babies. Often, those who survived had extensive scarring of their ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Clock
A clock or a timepiece is a device used to measure and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month and the year. Devices operating on several physical processes have been used over the millennia. Some predecessors to the modern clock may be considered as "clocks" that are based on movement in nature: A sundial shows the time by displaying the position of a shadow on a flat surface. There is a range of duration timers, a well-known example being the hourglass. Water clocks, along with the sundials, are possibly the oldest time-measuring instruments. A major advance occurred with the invention of the verge escapement, which made possible the first mechanical clocks around 1300 in Europe, which kept time with oscillating timekeepers like balance wheels., pp. 103–104., p. 31. Traditionally, in horology, the term ''clock'' was used for a stri ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Barrow Upon Humber
Barrow upon Humber is a village and civil parish in North Lincolnshire, England. The population (including Barrow Hann) at the 2011 census was 3,022. The village is situated near the Humber, about east from Barton-upon-Humber. The small port of Barrow Haven, north, on the railway line from Cleethorpes and Grimsby to Barton-upon-Humber handles timber from Latvia and Estonia. History Barrow contains the site of a late Anglo-Saxon monastery, which has been fully excavated. The location is now built over, but is marked by a plaque in the village. King Wulfhere gave land to Caedda (Saint Chad) in the 7th century at ''Ad Barvae'' (at the wood). It was on this site that the monastery was developed. The street adjacent to the monastery site is still known as St. Chad. A windmill, known as Rigg's Mill, was located on the western side of the village but was largely demolished in 1928. A limestone quarry existed on the south side of the village. Limestone was baked in retorts during t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Blue Plaque
A blue plaque is a permanent sign installed in a public place in the United Kingdom and elsewhere to commemorate a link between that location and a famous person, event, or former building on the site, serving as a historical marker. The term is used in the United Kingdom in two different senses. It may be used narrowly and specifically to refer to the "official" scheme administered by English Heritage, and currently restricted to sites within Greater London; or it may be used less formally to encompass a number of similar schemes administered by organisations throughout the UK. The plaques erected are made in a variety of designs, shapes, materials and colours: some are blue, others are not. However, the term "blue plaque" is often used informally to encompass all such schemes. The "official" scheme traces its origins to that launched in 1866 in London, on the initiative of the politician William Ewart, to mark the homes and workplaces of famous people. It has been administe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nostell Priory
Nostell Priory is a Palladian house in Nostell, West Yorkshire, England, near Crofton on the road to Doncaster from Wakefield. It dates from 1733, and was built for the Winn family on the site of a medieval priory. The Priory and its contents were given to the National Trust in 1953 by the trustees of the estate and Rowland Winn, 3rd Baron St Oswald. History Monastic history The priory was a 12th-century Augustinian foundation, dedicated to St Oswald, supported initially by Robert de Lacy of Pontefract, and Thurstan of York. By about 1114, Aldulf, confessor to Henry I of England, was prior of a group of regular canons at Nostell. It is probable that Scone Abbey was founded by monks from Nostell. Sir John Field, the first Copernican Astronomer of note in England, is believed to have studied at Nostell in his youth under the tutelage of Prior Alured Comwn. As part of the Dissolution of the Monasteries, the priory was seized and depredated in 1540 and granted to Dr Thomas Le ...
