David Steuart Erskine, 11th Earl of Buchan (12 June 174219 April 1829), styled Lord Cardross between 1747 and 1767, was a Scotland, Scottish antiquarian, founder of the Society of Antiquaries of Scotland in 1780, and patron of the arts and sciences. Background and education Erskine was the second but eldest surviving son of Henry Erskine, 10th Earl of Buchan, by Agnes, daughter of Sir James Steuart, 7th Baronet. He was the brother of Henry Erskine (lawyer), Henry Erskine and Thomas Erskine, 1st Baron Erskine, Lord Erskine.

Maclaurin's Inequality
In mathematics, Maclaurin's inequality, named after Colin Maclaurin, is a refinement of the inequality of arithmetic and geometric means. Let ''a''1, ''a''2, ..., ''a''''n'' be positive number, positive real numbers, and for ''k'' = 1, 2, ..., ''n'' define the averages ''S''''k'' as follows: :S_k = \frac. The numerator of this fraction is the elementary symmetric polynomial of degree ''k'' in the ''n'' variables ''a''1, ''a''2, ..., ''a''''n'', that is, the sum of all products of ''k'' of the numbers ''a''1, ''a''2, ..., ''a''''n'' with the indices in increasing order. The denominator is the number of terms in the numerator, the binomial coefficient \scriptstyle. Maclaurin's inequality is the following chain of inequality (mathematics), inequalities: :S_1 \geq \sqrt \geq \sqrt[3] \geq \cdots \geq \sqrt[n] with equality if and only if all the ''a''''i'' are equal. For ''n'' = 2, this gives the usual ... [...More Info...] [...Related Items...] 

Glendaruel
Glendaruel is a glen in the Cowal peninsula in Argyll and Bute, Scotland. The main settlement in Glendaruel (Scottish Gaelic, Gaelic: ''Gleann Dà Ruadhail'') is the Clachan of Glendaruel. Features The present Kilmodan Church was built in the Clachan of Glendaruel in 1783. The Clachan of Glendaruel is the current location of Kilmodan Primary School, and the ground of ColGlen Shinty Club. The ruined Dunans Castle is also located in Glendaruel, while Glendaruel Wood and Crags and the Ruel Estuary are both included in the List of Sites of Special Scientific Interest in Mid Argyll and Cowal. As the nearest Hospital is some miles away in Dunoon, a disused phone box in the village was converted to house a defibrillator. Just weeks before the installation, a tourist in Glendaruel had died from a heart attack. Decline The community is home to around 188 people as of 2008 and has been subject to a general decline in the late 20th century continuing into the early 21st century. Th ...

Scottish People
The Scots ( sco, Scots Fowk; gd, Albannaich) are a nation and ethnic group native to Scotland. Historically, they emerged in the Scotland in the Early Middle Ages, early Middle Ages from an amalgamation of two Celtic languages, Celticspeaking peoples, the Picts and Gaels, who founded the Kingdom of Scotland (or ''Kingdom of Alba, Alba'') in the 9th century. In the following two centuries, the Celticspeaking Hen Ogledd, Cumbrians of Kingdom of Strathclyde, Strathclyde and the Germanicspeaking AngloSaxons, Angles of north Northumbria became part of Scotland. In the Scotland in the High Middle Ages, High Middle Ages, during the 12thcentury Davidian Revolution, small numbers of Normans, Norman nobles migrated to the Lowlands. In the 13th century, the NorseGaels of the Kingdom of the Isles, Western Isles became part of Scotland, followed by the Norse of the Northern Isles in the 15th century.

Trisectrix Of Maclaurin
In geometry, the trisectrix of Maclaurin is a cubic plane curve notable for its trisectrix property, meaning it can be used to trisect an angle. It can be defined as locus of the point of intersection of two lines, each rotating at a uniform rate about separate points, so that the ratio of the rates of rotation is 1:3 and the lines initially coincide with the line between the two points. A generalization of this construction is called a sectrix of Maclaurin. The curve is named after Colin Maclaurin who investigated the curve in 1742. Equations Let two lines rotate about the points P = (0,0) and P_1 = (a, 0) so that when the line rotating about P has angle \theta with the ''x'' axis, the rotating about P_1 has angle 3\theta. Let Q be the point of intersection, then the angle formed by the lines at Q is 2\theta. By the law of sines, : = \! so the equation in polar coordinates is (up to translation and rotation) :r= a \frac = \frac = (4 \cos \theta  \sec \theta)\!. The curve is th ...

Braikenridge–Maclaurin Theorem
In geometry, the , named for 18th century British mathematicians William Braikenridge and Colin Maclaurin, is the converse to Pascal's theorem. It states that if the three intersection points of the three pairs of lines through opposite sides of a hexagon lie on a line ''L'', then the six vertices of the hexagon lie on a conic ''C''; the conic may be degenerate, as in Pappus's theorem. The Braikenridge–Maclaurin theorem may be applied in the Braikenridge–Maclaurin construction, which is a synthetic geometry, synthetic construction of the conic defined by five points, by varying the sixth point. Namely, Pascal's theorem states that given six points on a conic (the vertices of a hexagon), the lines defined by opposite sides intersect in three collinear points. This can be reversed to construct the possible locations for a sixth point, given five existing ones. References Theorems about polygons Conic sections {{elementarygeometrystub ...
