Edward Sang
Edward Sang FRSE FRSSA LLD (30 January 1805 – 23 December 1890) was a Scottish mathematician and civil engineer, best known for having computed large tables of logarithms, with the help of two of his daughters. These tables went beyond the tables of Henry Briggs, Adriaan Vlacq, and Gaspard de Prony. Personal life Sang was born in Kirkcaldy on 30 January 1805, the son of Jean Nicol and Edward Sang, Provost of Kirkcaldy. He attended the Subscription School in Kirkcaldy and from there went on to study at the University of Edinburgh. In the 1830s he is listed as a teacher of mathematics living at 32 St Andrew Square in Edinburgh. He was elected a Fellow of the Royal Society of Edinburgh in May 1836. In 1884 he was awarded their Makdougall-Brisbane Prize. He served as their Vice President 1883 to 1885. In 1841 he took the role of Professor of Mechanical Science at Manchester New College. In 1854 he briefly served as Professor of Mechanical Science in Constantinople. He returned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FRSSA
The Royal Scottish Society of Arts is a learned society in Scotland, dedicated to the study of science and technology. It was founded as The Society for the Encouragement of the Useful Arts in Scotland by Sir David Brewster in 1821 and dedicated to ''"the promotion of invention and enterprise"''. The Society was granted a Royal Charter in 1841. Background For many years the promotion of invention and improvements of all sorts was the main business of the Society, and its meetings were the focus of a large and active cross-section of Edinburgh society - academics, gentry, professionals such as civil engineers and lawyers, and skilled craftsmen such as instrument makers, engravers and printers. The Society's published Transactions provide a record of changes in technology, and the Society's archive is held by the National Library of Scotland, and is a valuable resource to researchers. In more recent times, the Society's meeting programme has been based on lectures given by expert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Makdougall-Brisbane Prize
The Royal Society of Edinburgh is Scotland's national academy of science and letters. It is a registered charity that operates on a wholly independent and non-partisan basis and provides public benefit throughout Scotland. It was established in 1783. , there are around 1,800 Fellows. The Society covers a broader selection of fields than the Royal Society of London, including literature and history. Fellowship includes people from a wide range of disciplines – science & technology, arts, humanities, medicine, social science, business, and public service. History At the start of the 18th century, Edinburgh's intellectual climate fostered many clubs and societies (see Scottish Enlightenment). Though there were several that treated the arts, sciences and medicine, the most prestigious was the Society for the Improvement of Medical Knowledge, commonly referred to as the Medical Society of Edinburgh, co-founded by the mathematician Colin Maclaurin in 1731. Maclaurin was unhappy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monthly Notices Of The Royal Astronomical Society
''Monthly Notices of the Royal Astronomical Society'' (MNRAS) is a peer-reviewed scientific journal covering research in astronomy and astrophysics. It has been in continuous existence since 1827 and publishes letters and papers reporting original research in relevant fields. Despite the name, the journal is no longer monthly, nor does it carry the notices of the Royal Astronomical Society. History The first issue of MNRAS was published on 9 February 1827 as ''Monthly Notices of the Astronomical Society of London'' and it has been in continuous publication ever since. It took its current name from the second volume, after the Astronomical Society of London became the Royal Astronomical Society (RAS). Until 1960 it carried the monthly notices of the RAS, at which time these were transferred to the newly established ''Quarterly Journal of the Royal Astronomical Society'' (1960–1996) and then to its successor journal ''Astronomy & Geophysics'' (since 1997). Until 1965, MNRAS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John West (mathematician)
Frontpage of ''Treatises'' (1838) John West (1756-1817) was a mathematician and priest from Scotland. Life and work Fourth child of Samuel West and Margaret Mein, his father died in 1766. West matriculated in the University of Saint Andrews in 1769 thanks to financial help of the presbytery clerk Dr. Adamson. He, like his brothers, studied mathematics under professor Nicolas Vilant. He was assistant of professor Vilant, who had poor health, but lacking of prospects in his native land, he emigrated to Jamaica, in 1784, the same year that ''Elements of Mathematics'' and ''A System of Shorthand'' were published. In Jamaica, West was initially teacher in the Manning's Free School at Savanna-la-Mar in Westmoreland Parish. In 1790 he was appointed rector of Saint Thomas in Morant Bay Morant Bay is a town in southeastern Jamaica and the capital of the parish of St. Thomas, located about 25 miles east of Kingston, the capital. The parish has a population of 94,410. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skew Arch
A skew arch (also known as an oblique arch) is a method of construction that enables an arch bridge to span an obstacle at some angle other than a right angle. This results in the faces of the arch not being perpendicular to its abutments and its plan view being a parallelogram, rather than the rectangle that is the plan view of a regular, or "square" arch. In the case of a masonry skew arch, the construction requires precise stonecutting, as the cuts do not form right angles, but once the principles were fully understood in the early 19th century, it became considerably easier and cheaper to build a skew arch of brick. The problem of building skew arch masonry bridges was addressed by a number of early civil engineers and mathematicians, including Giovanni Barbara (1726), William Chapman (1787), Benjamin Outram (1798), Peter Nicholson (1828), George Stephenson (1830), Edward Sang (1835), Charles Fox (1836), George W. Buck (1839) and William Froude (''c.'' 1844). History ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Georg Hagen
Johann (John) Georg Hagen (March 6, 1847 – September 6, 1930) was an Austrian Jesuit priest and astronomer. After serving as Director of the Georgetown University Observatory he was called to Rome by Pope Pius X in 1906 to be the first Jesuit director of the new Vatican Observatory. Father Hagen was also the spiritual director of Maria Elizabeth Hesselblad (1870-1957), who was baptized by him on August 15, 1902 and eventually was canonized on June 5, 2016 by Pope Francis. Early life Johann Georg Hagen was born in Bregenz, Austria on 6 March 1847, the son of a school teacher. Entering the Jesuit Order Johann entered the Society of Jesus, commonly known as the Jesuits, in Gorheim, Germany in 1863. He attended the Jesuit College Stella Matutina in Feldkirch, Austria and also studied mathematics and astronomy at the University of Bonn and the University of Münster.

Foucault's Pendulum
''Foucault's Pendulum'' (original title: ''Il pendolo di Foucault'' ) is a novel by Italian writer and philosopher Umberto Eco. It was first published in 1988, and an English translation by William Weaver appeared a year later. ''Foucault's Pendulum'' is divided into ten segments represented by the ten Sefiroth. The satirical novel is full of esoteric references to Kabbalah, alchemy, and conspiracy theory—so many that critic and novelist Anthony Burgess suggested that it needed an index. The pendulum of the title refers to an actual pendulum designed by French physicist Léon Foucault to demonstrate Earth's rotation, which has symbolic significance within the novel. Some believe that it refers to Michel Foucault, noting Eco's friendship with the French philosopher, but the author "specifically rejects any intentional reference to Michel Foucault"—this is regarded as one of his subtle literary jokes.

Planimeter
A planimeter, also known as a platometer, is a measuring instrument used to determine the area of an arbitrary two-dimensional shape. Construction There are several kinds of planimeters, but all operate in a similar way. The precise way in which they are constructed varies, with the main types of mechanical planimeter being polar, linear and Prytz or "hatchet" planimeters. The Swiss mathematician Jakob Amsler-Laffon built the first modern planimeter in 1854, the concept having been pioneered by Johann Martin Hermann in 1814. Many developments followed Amsler's famous planimeter, including electronic versions. The Amsler (polar) type consists of a two-bar linkage. At the end of one link is a pointer, used to trace around the boundary of the shape to be measured. The other end of the linkage pivots freely on a weight that keeps it from moving. Near the junction of the two links is a measuring wheel of calibrated diameter, with a scale to show fine rotation, and worm gearing for ...
