Murdoch Mackenzie (cartographer)
Murdoch Mackenzie, FRS (1712–1797) was a Scottish hydrographer and cartographer. He is known for his survey of the Orkney Islands: the subsequent maps, known as the Mackenzie Charts are still in use. He is also credited with the invention of thstation pointer a navigational and survey tool used to plot the horizontal angle fixes made with a sextant onto charts. Career Born in Orkney and employed by the Royal Navy, he became the first person to accurately chart the coastline around North Ronaldsay where many vessels had come to grief. He created a measured baseline and established station points along the shore to perform the triangulation equations for the survey. His calculations of latitude were very accurate despite the use of primitive methods compared to today. His work led to the construction of a lighthouse at Dennis Head on North Ronaldsay and his charts are still in use by shipping today. Mackenzie's survey of Orkney was featured in a 2005 episode of ''Map Man'', prese ...

Minehead
Minehead is a coastal town and civil parish in Somerset, England. It lies on the south bank of the Bristol Channel, north-west of the county town of Taunton, from the boundary with the county of Devon and in proximity of the Exmoor National Park. The parish of Minehead has a population of approximately 11,981, making it the most populous town in the western part of the Somerset West and Taunton local government district, which in turn, is the worst area in the country for social mobility. This figure includes Alcombe and Woodcombe, suburban villages which have been subsumed into Minehead. There is evidence of human occupation in the area since the Bronze and Iron Ages. Before the Norman conquest, it was held by Ælfgar, Earl of Mercia and after it by William de Moyon and his descendants, who administered the area from Dunster Castle, which was later sold to Sir George Luttrell and his family. There was a small port at Minehead by 1380, which grew into a major trading centre d ...

People From Orkney
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

1712 Births
Year 171 ( CLXXI) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Severus and Herennianus (or, less frequently, year 924 ''Ab urbe condita''). The denomination 171 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Marcus Aurelius forms a new military command, the ''praetentura Italiae et Alpium''.

The Orcadian
''The Orcadian'' is the oldest newspaper in Orkney, Scotland, first published in 1854. At first a monthly paper, it soon became a weekly. The newspaper is based in Kirkwall but printed in Glasgow for sale every Thursday. It is part of the Orkney Media Group, formed out of a partnership with a competing newspaper, ''Orkney Today'', in 2007. History The newspaper was first founded in 1854 as ''A Literary and Commercial Advertiser for Orkney and Zetland'' by James Urquhart Anderson, who established the first printing press on the island in the 1820s, and his son of the same name. The first issues were written by James, while his son printed the issues on hand set type. The Andersons were joined by Ayrshire journalist and editor W.H. Mackintosh when he married into the family in 1877, and since then, the newspaper has been owned by the Anderson-Mackintosh family. During the Second World War, ''The Orcadian'' published a special armed forces newspaper titled ''Orkney Blast.'' A c ...

Hadley's Quadrant
The octant, also called a reflecting quadrant, is a reflecting instrument used in navigation. Etymology The name ''octant'' derives from the Latin ''octans'' meaning ''eighth part of a circle'', because the instrument's arc is one eighth of a circle. ''Reflecting quadrant'' derives from the instrument using mirrors to reflect the path of light to the observer and, in doing so, doubles the angle measured. This allows the instrument to use a one-eighth of a turn to measure a quarter- turn or quadrant. Origin of the octant Newton's reflecting quadrant Isaac Newton's reflecting quadrant was invented around 1699. A detailed description of the instrument was given to Edmond Halley, but the description was not published until after Halley's death in 1742. It is not known why Halley did not publish the information during his life, as this prevented Newton from getting the credit for the invention that is generally given to John Hadley and Thomas Godfrey. One copy of this inst ...

Hydrograph
A hydrograph is a graph showing the rate of flow ( discharge) versus time past a specific point in a river, channel, or conduit carrying flow. The rate of flow is typically expressed in cubic meters or cubic feet per second (cms or cfs). It can also refer to a graph showing the volume of water reaching a particular outfall, or location in a sewerage network. Graphs are commonly used in the design of sewerage, more specifically, the design of surface water sewerage systems and combined sewers. Terminology ;Discharge: the rate of flow (volume per unit time) passing a specific location in a river, or other channel. The discharge is measured at a specific point in a river and is typically time variant. ;Approach Segment: the river flow before the storm (antecedent flow). ;Rising limb: The rising limb of the hydrograph, also known as concentration curve, reflects a prolonged increase in discharge from a catchment area, typically in response to a rainfall event. ;Peak discharge:'the hig ...
