David Gregory (mathematician)
David Gregory (originally spelt Gregorie) FRS (3 June 1659 – 10 October 1708) was a Scottish mathematician and astronomer. He was professor of mathematics at the University of Edinburgh, and later Savilian Professor of Astronomy at the University of Oxford, and a proponent of Isaac Newton's '' Principia''. Biography The fourth of the fifteen children of David Gregorie, a doctor from Kinnairdy, Banffshire, and Jean Walker of Orchiston, David was born in Upper Kirkgate, Aberdeen. The nephew of astronomer and mathematician James Gregory, David, like his influential uncle before him, studied at Aberdeen Grammar School and Marischal College (University of Aberdeen), from 1671 to 1675. The Gregorys were Jacobites and left Scotland to escape religious discrimination. Young David visited several countries on the continent, including the Netherlands (where he began studying medicine at Leiden University) and France, and did not return to Scotland until 1683. On 28 November 1683, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aberdeen
Aberdeen (; sco, Aiberdeen ; gd, Obar Dheathain ; la, Aberdonia) is a city in North East Scotland, and is the third most populous city in the country. Aberdeen is one of Scotland's 32 local government council areas (as Aberdeen City), and has a population estimate of for the city of Aberdeen, and for the local council area making it the United Kingdom's 39th most populous built-up area. The city is northeast of Edinburgh and north of London, and is the northernmost major city in the United Kingdom. Aberdeen has a long, sandy coastline and features an oceanic climate, with cool summers and mild, rainy winters. During the mid-18th to mid-20th centuries, Aberdeen's buildings incorporated locally quarried grey granite, which may sparkle like silver because of its high mica content. Since the discovery of North Sea oil in 1969, Aberdeen has been known as the offshore oil capital of Europe. Based upon the discovery of prehistoric villages around the mouths of the rivers ...

Scottish Mint
There were a number of mints in Scotland, for the production of the Scottish coinage. The most important mint was in the capital, Edinburgh, which was active from the reign of David I (1124–1153), and was the last to close, in the 19th century. Carlisle was probably the first Scottish mint in 1136. According to Bateson, David I began to mint coins after capturing the city.Bateson: ''Scottish Coins'' Mints at Bamburgh and Corbridge in Northumberland, under the control of David's son Henry, Earl of Northumberland, later returned to English control. Under Alexander III (1249–1286) there were 16 mints. In the reign of James IV (1488–1513), the sole mint was located at Edinburgh. After this time, the only other active mint was at Stirling, where bawbees were minted under Queen Mary. In 1581 the mint in Edinburgh was relocated to the environs of Cardinal David Beaton's lodging, which then belonged to Archibald Stewart. The buildings became the property of the mint master Thoma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Of 1707
The Acts of Union ( gd, Achd an Aonaidh) were two Acts of Parliament: the Union with Scotland Act 1706 passed by the Parliament of England, and the Union with England Act 1707 passed by the Parliament of Scotland. They put into effect the terms of the Treaty of Union that had been agreed on 22 July 1706, following negotiation between commissioners representing the parliaments of the two countries. By the two Acts, the Kingdom of England and the Kingdom of Scotlandwhich at the time were separate states with separate legislatures, but with the same monarchwere, in the words of the Treaty, "United into One Kingdom by the Name of Great Britain". The two countries had shared a monarch since the Union of the Crowns in 1603, when King James VI of Scotland inherited the English throne from his double first cousin twice removed, Queen Elizabeth I. Although described as a Union of Crowns, and in spite of James's acknowledgement of his accession to a single Crown, England and Scotland ...

Royal College Of Physicians Of Edinburgh
The Royal College of Physicians of Edinburgh (RCPE) is a medical royal college in Scotland. It is one of three organisations that sets the specialty training standards for physicians in the United Kingdom. It was established by Royal charter in 1681. The college claims to have 12,000 fellows and members worldwide. History The RCPE was formed by a royal charter, granted in 1681, with Sir Robert Sibbald recognised as playing a key part in the negotiations. Three applications preceded this and had been unsuccessful. There were 21 original Fellows, eleven of whom were graduates or students of the University of Leiden. The Universities (Scotland) Act 1858 resulted in several items from the College's Charter becoming obsolete, and they obtained a further charter on 31 October 1861. In 1920 the College enacted changes that allowed women to be admitted on the same terms as men. The charter was amended on 7 May 2005.

Achromatic Lens
An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue) into focus on the same plane. The most common type of achromat is the achromatic doublet, which is composed of two individual lenses made from glasses with different amounts of dispersion. Typically, one element is a negative (concave) element made out of flint glass such as F2, which has relatively high dispersion, and the other is a positive (convex) element made of crown glass such as BK7, which has lower dispersion. The lens elements are mounted next to each other, often cemented together, and shaped so that the chromatic aberration of one is counterbalanced by that of the other. In the most common type (shown), the positive power of the crown lens element is not quite equalled by the negative power of the flint lens element. Together they form a weak positive lens that will b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromatic Aberration
In optics, chromatic aberration (CA), also called chromatic distortion and spherochromatism, is a failure of a lens to focus all colors to the same point. It is caused by dispersion: the refractive index of the lens elements varies with the wavelength of light. The refractive index of most transparent materials decreases with increasing wavelength. Since the focal length of a lens depends on the refractive index, this variation in refractive index affects focusing. Chromatic aberration manifests itself as "fringes" of color along boundaries that separate dark and bright parts of the image. Types There are two types of chromatic aberration: ''axial'' (''longitudinal''), and ''transverse'' (''lateral''). Axial aberration occurs when different wavelengths of light are focused at different distances from the lens (focus ''shift''). Longitudinal aberration is typical at long focal lengths. Transverse aberration occurs when different wavelengths are focused at different positions i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The System Of The World
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a ...

Leiden University
Leiden University (abbreviated as ''LEI''; nl, Universiteit Leiden) is a Public university, public research university in Leiden, Netherlands. The university was founded as a Protestant university in 1575 by William the Silent, William, Prince of Orange, as a reward to the city of Leiden for its Siege of Leiden, defence against Spanish attacks during the Eighty Years' War. As the oldest institution of higher education in the Netherlands, it enjoys a reputation across Europe and the world. Known for its historic foundations and emphasis on the social sciences, the university came into particular prominence during the Dutch Golden Age, when scholars from around Europe were attracted to the Dutch Republic due to its climate of intellectual tolerance and Leiden's international reputation. During this time, Leiden became the home to individuals such as René Descartes, Rembrandt, Christiaan Huygens, Hugo Grotius, Baruch Spinoza and Baron d'Holbach. The university has seven academic f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacobitism
Jacobitism (; gd, Seumasachas, ; ga, Seacaibíteachas, ) was a political movement that supported the restoration of the senior line of the House of Stuart to the Monarchy of the United Kingdom, British throne. The name derives from the first name of James II and VII, which in Latin translates as ''Jacobus (name), Jacobus''. When James went into exile after the November 1688 Glorious Revolution, the Parliament of England argued that he had abandoned the Kingdom of England, English throne, which they offered to his Protestant daughter Mary II, and her husband William III of England, William III. In April, the Convention of Estates (1689), Scottish Convention held that he "forfeited" the throne of Scotland by his actions, listed in the Articles of Grievances. The Revolution thus created the principle of a contract between monarch and people, which if violated meant the monarch could be removed. Jacobites argued monarchs were appointed by God, or Divine right of kings, divine right, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aberdeen Grammar School
Aberdeen Grammar School is a state secondary school in Aberdeen, Scotland. It is one of thirteen secondary schools run by the Aberdeen City Council educational department. It is the oldest school in the city and one of the oldest grammar schools in the United Kingdom, with a history spanning more than 750 years. Founded around 1257, the year used in official school records, it began operating as a boys' school.
