1773 Phipps Expedition Towards The North Pole
The 1773 Phipps expedition towards the North Pole was a British Royal Navy expedition in which two ships under the commands of Constantine John Phipps and Skeffington Lutwidge sailed towards the North Pole in the summer of 1773 and became stuck in ice near Svalbard. Background In January 1773, on the initiative of its vice president Daines Barrington, the Secretary of the Royal Society, Matthew Maty, sent a letter to Lord Sandwich, the First Lord of the Admiralty, suggesting a voyage to the North Pole. Barrington had been influenced by the writings of the Swiss geographer Samuel Engel, who had suggested in his 1765 book the existence of a vast empty sea near the North Pole. Engel's explanation for the sea ice found in the Arctic was that most of it came from rivers, and so would only be found close to land. Sandwich, a friend of Daines Barrington, proposed the expedition to King George III, "which his Majesty was pleased to direct should be immediately undertaken". Preparat ...

A Voyage Towards The North Pole - Undertaken By His Majesty's Command, 1773 (1774) (14783478845)
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it f ...

Seven Years' War
The Seven Years' War (1756–1763) was a global conflict that involved most of the European Great Powers, and was fought primarily in Europe, the Americas, and Asia-Pacific. Other concurrent conflicts include the French and Indian War (1754–1763), the Carnatic Wars and the Anglo-Spanish War (1762–1763). The opposing alliances were led by Great Britain and France respectively, both seeking to establish global pre-eminence at the expense of the other. Along with Spain, France fought Britain both in Europe and overseas with land-based armies and naval forces, while Britain's ally Prussia sought territorial expansion in Europe and consolidation of its power. Long-standing colonial rivalries pitting Britain against France and Spain in North America and the West Indies were fought on a grand scale with consequential results. Prussia sought greater influence in the German states, while Austria wanted to regain Silesia, captured by Prussia in the previous war, and to contain Pruss ...

Evaporator (marine)
An evaporator, distiller or distilling apparatus is a piece of ship's equipment used to produce fresh drinking water from sea water by distillation. As fresh water is bulky, may spoil in storage, and is an essential supply for any long voyage, the ability to produce more fresh water in mid-ocean is important for any ship. Early evaporators on sailing vessels Although distillers are often associated with steam ships, their use pre-dates this. Obtaining fresh water from seawater is a theoretically simple system that, in practice, presented many difficulties. While there are numerous effective methods today, early desalination efforts had low yields and often could not produce potable water. At first, only larger warships and some exploratory ships were fitted with distilling apparatus: a warship's large crew naturally needed a large supply of water, more than they could stow on board in advance. Cargo ships, with their smaller crews, merely carried their supplies with them. A s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chip Log
A chip log, also called common log, ship log, or just log, is a navigation tool mariners use to estimate the speed of a vessel through water. The word ''knot'', to mean nautical mile per hour, derives from this measurement method. History All nautical instruments that measure the speed of a ship through water are known as logs. This nomenclature dates back to the days of sail, when sailors tossed a log attached to a rope knotted at regular intervals off the stern of a ship. Sailors counted the number of knots that passed through their hands in a given time to determine the ship's speed. Today, sailors and aircraft pilots still express speed in knots. Construction A chip log consists of a wooden board attached to a line (the log-line). The log-line has a number of knots at uniform intervals. The log-line is wound on a reel so the user can easily pay it out. Over time, log construction standardized. The shape is a quarter circle, or quadrant with a radius of or , and thi ...

Pierre Bouguer
Pierre Bouguer () (16 February 1698, Croisic – 15 August 1758, Paris) was a French mathematician, geophysicist, geodesist, and astronomer. He is also known as "the father of naval architecture". Career Bouguer's father, Jean Bouguer, one of the best hydrographers of his time, was Regius Professor of hydrography at Le Croisic in lower Brittany, and author of a treatise on navigation. He taught his sons Pierre and Jan at their home, where he also taught private students. In 1714, at the age of 16, Pierre was appointed to succeed his deceased father as professor of hydrography. In 1727 he gained the prize given by the French Academy of Sciences for his paper ''On the masting of ships'', beating Leonhard Euler; and two other prizes, one for his dissertation ''On the best method of observing the altitude of stars at sea'', the other for his paper ''On the best method of observing the variation of the compass at sea''. These were published in the Prix de l'Académie des Science ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Arnold (watchmaker)
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 ...

He was living with his parents in St Clement Danes at the time. Jeffreys created a pocket watch for John Harrison, who later used ideas from pocket watches in his H4 chronometer. Kendall set up his own business in 1742, working with Thomas Mudge to make watches, working for the watch and clock maker George Graham. In 1765 he was one of six experts selected by the Board of Longitude to witness the operation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Horatio Nelson, 1st Viscount Nelson
Vice-Admiral Horatio Nelson, 1st Viscount Nelson, 1st Duke of Bronte (29 September 1758 – 21 October 1805) was a British flag officer in the Royal Navy. His inspirational leadership, grasp of strategy, and unconventional tactics brought about a number of decisive British naval victories during the French Revolutionary and Napoleonic Wars. He is widely regarded as one of the greatest naval commanders in history. Nelson was born into a moderately prosperous Norfolk family and joined the navy through the influence of his uncle, Maurice Suckling, a high-ranking naval officer. Nelson rose rapidly through the ranks and served with leading naval commanders of the period before obtaining his own command at the age of 20, in 1778. He developed a reputation for personal valour and firm grasp of tactics, but suffered periods of illness and unemployment after the end of the American War of Independence. The outbreak of the French Revolutionary Wars allowed Nelson to return to service, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olaudah Equiano
Olaudah Equiano (; c. 1745 – 31 March 1797), known for most of his life as Gustavus Vassa (), was a writer and abolitionist from, according to his memoir, the Eboe (Igbo) region of the Kingdom of Benin (today southern Nigeria). Enslaved as a child in Africa, he was shipped to the Caribbean as a victim of the Atlantic slave trade and sold as a slave to a Royal Navy officer. He was sold twice more but purchased his freedom in 1766. As a freedman in London, Equiano supported the British abolitionist movement. He was part of the Sons of Africa, an abolitionist group comprised of Africans living in Britain, and he was active among leaders of the anti-slave trade movement in the 1780s. He published his autobiography, ''The Interesting Narrative of the Life of Olaudah Equiano'' (1789), which depicted the horrors of slavery. It went through nine editions in his lifetime and helped obtain passing of the British Slave Trade Act 1807, which abolished the slave trade. Equiano married a ...

Philippe D'Auvergne
} Philippe d'Auvergne (13 November 1754 – 18 September 1816) was a British naval officer and the adopted son of Godefroy de La Tour d'Auvergne the sovereign Duke of Bouillon. He chose a career in the Royal Navy that spanned a period of history where Great Britain was at the centre of wars and empire building and took him from Boston and the War of Independence to espionage with French Royalists; prisoner of war to shipwrecked; all this whilst hoping to become a Walloons, Walloon ruler or, at least, heir to a princely fortune. Early life Philippe D'Auvergne was born in Jersey, where his family had lived for four centuries. His mother Elizabeth, the daughter of Philip Le Geyt, died giving birth to him. His father, Charles, was an ex-British Army officer, advisor to British Cabinet Committees and aide-de-camp to various Governors; they included John Huske, Governor from 1749 to 1761, who left Charles £2,000 when he died in January 1761.

Israel Lyons
Israel Lyons the Younger (1739–1775), mathematician and botanist, was born at Cambridge, the son of Israel Lyons the elder (died 1770). He was regarded as a prodigy, especially in mathematics, and Robert Smith, master of Trinity College, took him under his wing and paid for his attendance. Biography Due to his Ashkenazi Jewish origins, Lyons was not permitted to become an official member of the University of Cambridge. Nevertheless, his brilliance resulted in his publication ''Treatise on Fluxions'' at the age of 19, and his enthusiasm for botany resulted in a published survey of Cambridge flora a few years later. An Oxford undergraduate, Joseph Banks, paid Lyons to deliver a series of botany lectures at the University of Oxford. Lyons was selected by the Astronomer Royal to compute astronomical tables for the Nautical Almanac. Later, Banks secured Lyons a position as the astronomer for the 1773 North Pole voyage led by Constantine Phipps, 2nd Baron Mulgrave. Lyons married, ...
