John Playfair
John Playfair FRSE, FRS (10 March 1748 – 20 July 1819) was a Church of Scotland minister, remembered as a scientist and mathematician, and a professor of natural philosophy at the University of Edinburgh. He is best known for his book ''Illustrations of the Huttonian Theory of the Earth'' (1802), which summarised the work of James Hutton. It was through this book that Hutton's principle of uniformitarianism, later taken up by Charles Lyell, first reached a wide audience. Playfair's textbook ''Elements of Geometry'' made a brief expression of Euclid's parallel postulate known now as Playfair's axiom. In 1783 he was a co-founder of the Royal Society of Edinburgh. He served as General Secretary to the society 1798–1819. Life Born at Benvie, slightly west of Dundee to Margaret Young (1719/20 – 1805) and Reverend James Playfair (died 1772), the kirk minister of Liff and Benvie. Playfair was educated at home until the age of 14, when he entered the University of St Andrews ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Raeburn
Sir Henry Raeburn (; 4 March 1756 – 8 July 1823) was a Scottish portrait painter. He served as Portrait Painter to King George IV in Scotland. Biography Raeburn was born the son of a manufacturer in Stockbridge, on the Water of Leith: a former village now within the city of Edinburgh. He had an older brother, born in 1744, called William Raeburn. His ancestors were believed to have been soldiers, and may have taken the name "Raeburn" from a hill farm in Annandale, held by Sir Walter Scott's family. Orphaned, he was supported by William and placed in Heriot's Hospital, where he received an education. At the age of fifteen he was apprenticed to the goldsmith James Gilliland of Edinburgh, and various pieces of jewellery, mourning rings and the like, adorned with minute drawings on ivory by his hand, still exist. When the medical student Charles Darwin died in 1778, his friend and professor Andrew Duncan took a lock of his student's hair to the jeweller whose apprentice, Rae ...

Church Of Scotland
The Church of Scotland ( sco, The Kirk o Scotland; gd, Eaglais na h-Alba) is the national church in Scotland. The Church of Scotland was principally shaped by John Knox, in the Reformation of 1560, when it split from the Catholic Church and established itself as a church in the reformed tradition. The church is Calvinist Presbyterian, having no head of faith or leadership group and believing that God invited the church's adherents to worship Jesus. The annual meeting of its general assembly is chaired by the Moderator of the General Assembly of the Church of Scotland. The Church of Scotland celebrates two sacraments, Baptism and the Lord's Supper, as well as five other rites, such as Confirmation and Matrimony. The church adheres to the Bible and the Westminster Confession of Faith, and is a member of the World Communion of Reformed Churches. History Presbyterian tradition, particularly that of the Church of Scotland, traces its early roots to the church foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marischal College
Marischal College ( ) is a large granite building on Broad Street in the centre of Aberdeen in north-east Scotland, and since 2011 has acted as the headquarters of Aberdeen City Council. However, the building was constructed for and is on long-term lease from the University of Aberdeen, which still uses parts of the building to store its museum collections. Today, it provides corporate office space and public access to council services, adjacent to the Town House, the city's historic seat of local government. Many Aberdonians consider Marischal College to be an icon of the "Granite City" and to symbolise the zenith of Aberdeen's granite-working industry. The construction of the modern college building began in 1835, following the demolition of previous buildings on the site, and was completed in its present form in the early 1900s. It is the second largest granite building in the world. Formerly the seat of the Marischal College and University of Aberdeen founded in 1593, the b ...

Edinburgh University
The University of Edinburgh ( sco, University o Edinburgh, gd, Oilthigh Dhùn Èideann; abbreviated as ''Edin.'' in Post-nominal letters, post-nominals) is a Public university, public research university based in Edinburgh, Scotland. Granted a royal charter by King James VI and I, James VI in 1582 and officially opened in 1583, it is one of Scotland's Ancient universities of Scotland, four ancient universities and the List of oldest universities in continuous operation, sixth-oldest university in continuous operation in the English-speaking world. The university played an important role in Edinburgh becoming a chief intellectual centre during the Scottish Enlightenment and contributed to the city being nicknamed the "Etymology of Edinburgh#Athens of the North, Athens of the North." Edinburgh is ranked among the top universities in the United Kingdom and the world. Edinburgh is a member of several associations of research-intensive universities, including the Coimbra Group, Le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kirk Minister
A Church of Scotland congregation is led by its minister and elders. Both of these terms are also used in other Christian denominations: see Minister (Christianity) and Elder (Christianity). This article discusses the specific understanding of their roles and functions in the Scottish Church. Terminology The Greek term , used in the New Testament as a designation for the leaders of the Early Church (e.g. Acts 11.30), has three different equivalents in English: ''elder'', ''presbyter'' and ''priest''. ''Priest'' is the oldest, a borrowing into Old English via Latin, ''elder'' (first attested 1526) is a translation of the underlying meaning of the Greek word, and ''presbyter'' (1597) is learned correction of the loan-word. However, the semantics of ''priest'' are complicated by the fact that it is traditionally used also as the translation of a different New Testament Greek word, , which refers to those who perform sacrificial rites in the Jerusalem temple and in pagan ...

Dundee
Dundee (; sco, Dundee; gd, Dùn Dè or ) is Scotland's fourth-largest city and the 51st-most-populous built-up area in the United Kingdom. The mid-year population estimate for 2016 was , giving Dundee a population density of 2,478/km2 or 6,420/sq mi, the second-highest in Scotland. It lies within the eastern central Lowlands on the north bank of the Firth of Tay, which feeds into the North Sea. Under the name of Dundee City, it forms one of the 32 council areas used for local government in Scotland. Within the boundaries of the historic county of Angus, the city developed into a burgh in the late 12th century and established itself as an important east coast trading port. Rapid expansion was brought on by the Industrial Revolution, particularly in the 19th century when Dundee was the centre of the global jute industry. This, along with its other major industries, gave Dundee its epithet as the city of "jute, jam and journalism". Today, Dundee is promoted as "One ...

Parallel Postulate
In geometry, the parallel postulate, also called Euclid's fifth postulate because it is the fifth postulate in Euclid's ''Elements'', is a distinctive axiom in Euclidean geometry. It states that, in two-dimensional geometry: ''If a line segment intersects two straight lines forming two interior angles on the same side that are less than two right angles, then the two lines, if extended indefinitely, meet on that side on which the angles sum to less than two right angles.'' This postulate does not specifically talk about parallel lines; it is only a postulate related to parallelism. Euclid gave the definition of parallel lines in Book I, Definition 23 just before the five postulates. ''Euclidean geometry'' is the study of geometry that satisfies all of Euclid's axioms, ''including'' the parallel postulate. The postulate was long considered to be obvious or inevitable, but proofs were elusive. Eventually, it was discovered that inverting the postulate gave valid, albeit diffe ...

Euclid
Euclid (; grc-gre, Εὐκλείδης; BC) was an ancient Greek mathematician active as a geometer and logician. Considered the "father of geometry", he is chiefly known for the '' Elements'' treatise, which established the foundations of geometry that largely dominated the field until the early 19th century. His system, now referred to as Euclidean geometry, involved new innovations in combination with a synthesis of theories from earlier Greek mathematicians, including Eudoxus of Cnidus, Hippocrates of Chios, Thales and Theaetetus. With Archimedes and Apollonius of Perga, Euclid is generally considered among the greatest mathematicians of antiquity, and one of the most influential in the history of mathematics. Very little is known of Euclid's life, and most information comes from the philosophers Proclus and Pappus of Alexandria many centuries later. Until the early Renaissance he was often mistaken for the earlier philosopher Euclid of Megara, causing his biogr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Lyell
Sir Charles Lyell, 1st Baronet, (14 November 1797 – 22 February 1875) was a Scottish geologist who demonstrated the power of known natural causes in explaining the earth's history. He is best known as the author of ''Principles of Geology'' (1830–33), which presented to a wide public audience the idea that the earth was shaped by the same natural processes still in operation today, operating at similar intensities. The philosopher William Whewell termed this gradualistic view "uniformitarianism" and contrasted it with catastrophism, which had been championed by Georges Cuvier and was better accepted in Europe. The combination of evidence and eloquence in ''Principles'' convinced a wide range of readers of the significance of "deep time" for understanding the earth and environment. Lyell's scientific contributions included a pioneering explanation of climate change, in which shifting boundaries between oceans and continents could be used to explain long-term variations ...

Uniformitarianism (science)
Uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle, is the assumption that the same natural laws and processes that operate in our present-day scientific observations have always operated in the universe in the past and apply everywhere in the universe., "''The assumption of spatial and temporal invariance of natural laws is by no means unique to geology since it amounts to a warrant for inductive inference'' which, as Bacon showed nearly four hundred years ago, is ''the basic mode of reasoning in empirical science. Without assuming this spatial and temporal invariance, we have no basis for extrapolating from the known to the unknown'' and, therefore, no way of reaching general conclusions from a finite number of observations." It refers to invariance in the metaphysical principles underpinning science, such as the constancy of cause and effect throughout space-time, but has also been used to describe spatiotemporal invariance of physical ...
