George Adams (scientist, Died 1795)
George Adams the younger (1750–1795) was an English scientist, optician and scientific writer. He was mathematical instrument maker to King George III of Great Britain, succeeding his father George Adams in the post. He also made globes. Around 1770, Adams invented the lucernal microscope, a type of projection microscope where the image is projected on a screen by a large oil lamp, as to make it easier to draw or trace the image. In politics Adams was a Tory, and as such was received with favour at court by George III. He died 14 August 1795, at Southampton, and was succeeded in his business and in the post of mathematical instrument maker to the king by his brother, Dudley Adams. Works Adams wrote elementary scientific works, and on the use of mathematical instruments. He often combined religious with a scientific content, against, according to the ''Gentleman's Magazine ''The Gentleman's Magazine'' was a monthly magazine founded in London, England, by Edward Cave i ...

George III
George III (George William Frederick; 4 June 173829 January 1820) was King of Great Britain and of Ireland from 25 October 1760 until the union of the two kingdoms on 1 January 1801, after which he was King of the United Kingdom of Great Britain and Ireland until his death in 1820. He was the longest-lived and longest-reigning king in British history. He was concurrently Duke and Prince-elector of Brunswick-Lüneburg ("Hanover") in the Holy Roman Empire before becoming King of Hanover on 12 October 1814. He was a monarch of the House of Hanover but, unlike his two predecessors, he was born in Great Britain, spoke English as his first language and never visited Hanover. George's life and reign were marked by a series of military conflicts involving his kingdoms, much of the rest of Europe, and places farther afield in Africa, the Americas and Asia. Early in his reign, Great Britain defeated France in the Seven Years' War, becoming the dominant European power in North America ...

Tories (British Political Party)
The Tories were a loosely organised political faction and later a political party, in the Parliaments of England, Scotland, Ireland, Great Britain and the United Kingdom. They first emerged during the 1679 Exclusion Crisis, when they opposed Whig efforts to exclude James, Duke of York from the succession on the grounds of his Catholicism. Despite their fervent opposition to state-sponsored Catholicism, Tories opposed exclusion in the belief inheritance based on birth was the foundation of a stable society. After the succession of George I in 1714, the Tories were excluded from government for nearly 50 years and ceased to exist as an organised political entity in the early 1760s, although it was used as a term of self-description by some political writers. A few decades later, a new Tory party would rise to establish a hold on government between 1783 and 1830, with William Pitt the Younger followed by Robert Jenkinson, 2nd Earl of Liverpool. The Whigs won control of Parl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gentleman's Magazine
''The Gentleman's Magazine'' was a monthly magazine founded in London, England, by Edward Cave in January 1731. It ran uninterrupted for almost 200 years, until 1922. It was the first to use the term ''magazine'' (from the French ''magazine'', meaning "storehouse") for a periodical. Samuel Johnson's first regular employment as a writer was with ''The Gentleman's Magazine''. History The original complete title was ''The Gentleman's Magazine: or, Trader's monthly intelligencer''. Cave's innovation was to create a monthly digest of news and commentary on any topic the educated public might be interested in, from commodity prices to Latin poetry. It carried original content from a stable of regular contributors, as well as extensive quotations and extracts from other periodicals and books. Cave, who edited ''The Gentleman's Magazine'' under the pen name "Sylvanus Urban", was the first to use the term ''magazine'' (meaning "storehouse") for a periodical. Contributions to the magazi ...

B21438559
B, or b, is the second letter of the Latin-script alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is '' bee'' (pronounced ), plural ''bees''. It represents the voiced bilabial stop in many languages, including English. In some other languages, it is used to represent other bilabial consonants. History Old English was originally written in runes, whose equivalent letter was beorc , meaning "birch". Beorc dates to at least the 2nd-century Elder Futhark, which is now thought to have derived from the Old Italic alphabets' either directly or via Latin . The uncial and half-uncial introduced by the Gregorian and Irish missions gradually developed into the Insular scripts' . These Old English Latin alphabets supplanted the earlier runes, whose use was fully banned under King Canute in the early 11th century. The Norman Conquest popularised the Carolingian half-uncial forms which lat ... [...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 ...

Year 175 ( CLXXV) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar.
