Joseph Harris (astronomer)
Joseph Harris (1703 – 1764) was a British blacksmith, astronomer, navigator, economist, natural philosopher, government adviser and King's Assay Master at the Royal Mint. ''Of Joseph Harris, the eldest, who married one of the daughters, and heiress, of Thomas Jones, of Tredustan, little has been recorded beyond the information derived from his monument in the church. His talents were highly respectable, and indeed pre-eminent. But though he wrote several astronomical treatises, which are highly thought of, and was esteemed by the learned and great of his day, no biographer has written his life: no anecdotes of him have been preserved; nor have his virtues or talents been recorded farther than as they appear in his works, which in general are anonymous. Indeed, that ''modesty'', which is so amiable in him, seems to have descended to his posterity where he was born, for after all the enquiries I have made with respect of him, instead of learning any other particulars of ...

Trefeca
Trefeca (also Trefecca, Trevecca, and Trevecka), located between Talgarth and Llangorse Lake in what is now south Powys in Wales, was the birthplace and home of the 18th-century Methodist leader Howell Harris ( cy, Hywel Harris, italic=no). It was also the site of two Calvinistic Methodist colleges at different times; the first sponsored by Selina, Countess of Huntingdon (an English methodist leader) in the late eighteenth century; the second supported by the Welsh Calvinistic Methodist Connexion in the later nineteenth century. Teulu Trefeca In 1752, Harris, who was born in Trefeca and was one of the foremost leaders of the Welsh Methodist revival, established a Christian community there known as ''Teulu Trefeca'' ('the Trefeca Family'), modelled on the Moravian Herrnhutt community of Count von Zinzendorf. John Wesley preached for Harris's 'family' when visiting Trevecca in August 1769 for the first anniversary of Trevecca College. The additions to Harris's family house were ...

Joiner
A joiner is an artisan and tradesperson who builds things by joining pieces of wood, particularly lighter and more ornamental work than that done by a carpenter, including furniture and the "fittings" of a house, ship, etc. Joiners may work in a workshop, because the formation of various joints is made easier by the use of non-portable, powered machinery, or on job site. A joiner usually produces items such as interior and exterior doors, windows, stairs, tables, bookshelves, cabinets, furniture, etc. In shipbuilding a ''marine joiner'' may work with materials other than wood such as linoleum, fibreglass, hardware, and gaskets. The terms ''joinery'' and ''joiner'' are in common use in the UK, Australia, and New Zealand. The term is not in common use in North America, although the main trade union for American carpenters is called the United Brotherhood of Carpenters and Joiners of America. In the UK, an apprentice of wood occupations could choose to study ''bench joinery'' or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orrery
An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model. It may also represent the relative sizes of these bodies; however, since accurate scaling is often not practical due to the actual large ratio differences, a subdued approximation may be used instead. Though the Greeks had working planetaria, the first orrery that was a planetarium of the modern era was produced in 1704, and one was presented to Charles Boyle, 4th Earl of Orrery – hence the name. They are typically driven by a clockwork mechanism with a globe representing the Sun at the centre, and with a planet at the end of each of the arms. History Ancient versions The Antikythera mechanism, discovered in 1901 in a wreck off the Greek island of Antikythera in the Mediterranean Sea, (it now resides in the National Archaeological Museum of Athens) and extensively studied, exhibited the diu ...

Portobelo, Colón
Portobelo (Modern Spanish: "Puerto Bello" ("beautiful port"), historically in Portuguese: Porto Belo) is a historic port and corregimiento in Portobelo District, Colón Province, Panama, Central America, with a population of 4,559 . Located on the northern part of the Isthmus of Panama, it is northeast of the modern port of Colón now at the Atlantic entrance to the Panama Canal. It functions as the seat of Portobelo District. Established in 1597 during the time of the Spanish empire due to its deep natural harbor, it served as one of the two ports (together with Veracruz to the northwest) through which Spanish treasure was shipped from the mines of Peru (via Panama City on the Pacific side of the Isthmus and overland to Portobelo) back to Spain. The city was repeatedly captured by British privateers and pirates, culminating in a successful siege by the Royal Navy in 1739, during the War of Jenkin's Ear. Its economy received a major boost in the late-19th century during the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Veracruz, Veracruz
Veracruz (), known officially as Heroica Veracruz, is a major port city and municipal seat for the surrounding municipality of Veracruz on the Gulf of Mexico in the Mexican state of Veracruz. The city is located along the coast in the central part of the state, southeast of the state capital Xalapa along Federal Highway 140. It is the state's most populous city, with a population that is greater than the municipality's population, as part of the city of Veracruz extends into the neighboring Boca del Río Municipality. At the 2010 census, the city had 554,830 inhabitants, 428,323 in Veracruz Municipality and 126,507 in Boca del Río Municipality.2010 census tables: INEGI Developed during Spanish colonization, Veracruz has been Mexico's oldest, largest, and historically most significant port.

South Sea Company
The South Sea Company (officially The Governor and Company of the merchants of Great Britain, trading to the South Seas and other parts of America, and for the encouragement of the Fishery) was a British joint-stock company founded in January 1711, created as a public-private partnership to consolidate and reduce the cost of the national debt. To generate income, in 1713 the company was granted a monopoly (the Asiento de Negros) to supply African slaves to the islands in the "South Seas" and South America. When the company was created, Britain was involved in the War of the Spanish Succession and Spain and Portugal controlled most of South America. There was thus no realistic prospect that trade would take place, and as it turned out, the Company never realised any significant profit from its monopoly. However, Company stock rose greatly in value as it expanded its operations dealing in government debt, and peaked in 1720 before suddenly collapsing to little above its ...

Gulf Of Mexico
The Gulf of Mexico ( es, Golfo de México) is an oceanic basin, ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexico, Mexican States of Mexico, states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan, and Quintana Roo; and on the southeast by Cuba. The Southern United States, Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are often referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific Ocean, Pacific coasts). The Gulf of Mexico took shape approximately 300 million years ago as a result of plate tectonics.Huerta, A.D., and D.L.

John Senex
John Senex (1678 in Ludlow, Shropshire – 1740 in London) was an English cartographer, engraver and explorer. He was also an astrologer, geologist, and geographer to Queen Anne of Great Britain, editor and seller of antique maps and most importantly creator of the pocket-size map of the world. He owned a business on Fleet Street in London, where he sold maps. Importance He was one of the principal cartographers of the 18th century. He started his apprenticeship with Robert Clavell, at the Stationers Company, in 1692. Senex is famous for his maps of the world, some of which have added elevations, and which feature minuscule detailed engravings. Many of these maps can be found in museum collections; rarely, copies are available for private sale. Some copies are held in the National Maritime Museum; many of his maps are now in the possession of Trinity College Dublin. Having worked and collaborated with Charles Price, Senex created a series of engravings for the London Almanac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 post was created by King Charles II in 1675, at the same time as he founded the Royal Observatory Greenwich. He appointed John Flamsteed, instructing him "." 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] |
Quadrant (astronomy)
A galactic quadrant, or quadrant of the Galaxy, is one of four circular sectors in the division of the Milky Way Galaxy. Quadrants in the galactic coordinate system In actual astronomical practice, the delineation of the galactic quadrants is based upon the galactic coordinate system, which places the Sun as the pole of the mapping system. The Sun is used instead of the Galactic Center for practical reasons since all astronomical observations (by humans) to date have been based on Earth or within the Solar System. Delineation Quadrants are described using ordinals—for example, "1st galactic quadrant" "second galactic quadrant," or "third quadrant of the Galaxy."M. Lampton ''et al''An All-Sky Catalog of Faint Extreme Ultraviolet Sources''The Astrophysical Journal Supplement Series ''. 1997 Viewing from the north galactic pole with 0 degrees (°) as the ray that runs starting from the Sun and through the galactic center, the quadrants are as follows (where is galactic lo ...

Edmond Halley
Edmond (or Edmund) Halley (; – ) was an English astronomer, mathematician and physicist. He was the second Astronomer Royal in Britain, succeeding John Flamsteed in 1720. From an observatory he constructed on Saint Helena in 1676–77, Halley catalogued the southern celestial hemisphere and recorded a transit of Mercury across the Sun. He realised that a similar transit of Venus could be used to determine the distances between Earth, Venus, and the Sun. Upon his return to England, he was made a fellow of the Royal Society, and with the help of King Charles II, was granted a master's degree from Oxford. Halley encouraged and helped fund the publication of Isaac Newton's influential ''Philosophiæ Naturalis Principia Mathematica'' (1687). From observations Halley made in September 1682, he used Newton's laws of motion to compute the periodicity of Halley's Comet in his 1705 ''Synopsis of the Astronomy of Comets''. It was named after him upon its predicted return in 1758, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
