David Brewster
Sir David Brewster Knight of the Royal Guelphic Order, KH President of the Royal Society of Edinburgh, PRSE Fellow of the Royal Society of London, FRS Fellow of the Society of Antiquaries of Scotland, FSA Scot Fellow of the Scottish Society of Arts, FSSA Member of the Institution of Civil Engineers, MICE (11 December 178110 February 1868) was a British scientist, inventor, author, and academic administrator. In science he is principally remembered for his experimental work in physical optics, mostly concerned with the study of the Polarization (waves), polarization of light and including the discovery of Brewster's angle. He studied the birefringence of crystals under compression and discovered photoelasticity, thereby creating the field of optical mineralogy.A. D. Morrison-Low (2004) "Brewster, Sir David (1781–1868)" in ''Oxford Dictionary of National Biography'' For this work, William Whewell dubbed him the "father of modern experimental optics" and "the Johannes Kepler of o ...

Jedburgh
Jedburgh ( ; ; or ) is a town and former royal burgh in the Scottish Borders and the traditional county town of the Shires of Scotland, historic county of Roxburghshire. History Jedburgh began as ''Jedworð'', the "worth" or enclosed settlement on the Jed. Later the more familiar word "burgh" was substituted for this, though the original name survives as Jeddart/Jethart. Bishop Ecgred of Lindisfarne founded a church at Jedburgh in the 9th century, and King David I of Scotland made it a priory between 1118 and 1138, housing Augustinians, Augustinian monks from Beauvais in France. The abbey was founded in 1147, but border wars with England in the 16th century left it a ruin. The deeply religious Scottish king Malcolm IV of Scotland, Malcolm IV died at Jedburgh in 1165, aged 24. His death is thought to have been caused by Paget's disease of bone. David I built a Jedburgh Castle, castle at Jedburgh, and in 1174 it was one of five fortresses ceded to England. It was an occasiona ...

Photoelasticity
In materials science, photoelasticity describes changes in the optical properties of a material under mechanical deformation. It is a property of all dielectric media and is often used to experimentally determine the stress distribution in a material. History The photoelastic phenomenon was first discovered by the Scottish physicist David Brewster, who immediately recognized it as stress-induced birefringence. That diagnosis was confirmed in a direct refraction experiment by Augustin-Jean Fresnel. * Reprinted in H. de Senarmont, E. Verdet, and L. Fresnel (eds.), ''Oeuvres complètes d'Augustin Fresnel'', vol. 1 (1866)pp. 713–18* Translated as Experimental frameworks were developed at the beginning of the twentieth century with the works of E.G. Coker and L.N.G. Filon of University of London. Their book ''Treatise on Photoelasticity'', published in 1930 by Cambridge Press, became a standard text on the subject. Between 1930 and 1940, many othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

President Of The Royal Society Of Edinburgh
The Royal Society of Edinburgh (RSE) 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 range of fields than the Royal Society of London, including literature and history. The Fellowship includes people from a wide range of disciplines: science and 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 un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knight Of The Royal Guelphic Order
The Royal Guelphic Order (), sometimes referred to as the Hanoverian Guelphic Order, is a Kingdom of Hanover, Hanoverian order of chivalry instituted on 28 April 1815 by the Prince Regent (later King George IV). It takes its name from the House of Guelph, of which the House of Hanover was a branch. Since Hanover and the United Kingdom personal union, shared a monarch until 1837, the order was frequently bestowed upon British subjects. History Until 1837 the order was frequently awarded to officers in the British Royal Navy, Navy and British Army, Army, although it was still classed as a foreign order, with British members of the order not entitled to style themselves as "Sir" unless they were also created Knights Bachelor, as many were. The British link ended in 1837 when Kingdom of Hanover, Hanover's royal union with Great Britain ended, with Ernest Augustus, King of Hanover, Ernest Augustus becoming King of Hanover and Queen Victoria ascending the British throne.

Scottish Society Of Arts
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 ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Medal
The Royal Medal, also known as The Queen's Medal and The King's Medal (depending on the gender of the monarch at the time of the award), is a silver-gilt medal, of which three are awarded each year by the Royal Society. Two are given for "the most important contributions to the advancement of natural knowledge," and one for "distinguished contributions in the applied sciences", all of which are done within the Commonwealth of Nations. Background The award was created by George IV and awarded first during 1826. Initially there were two medals awarded, both for the most important discovery within the year previous, a time period which was lengthened to five years and then shortened to three. The format was endorsed by William IV and Victoria, who had the conditions changed during 1837 so that mathematics was a subject for which a Royal Medal could be awarded, albeit only every third year. The conditions were changed again during 1850 so that: ... the Royal Medals in each year sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keith Prize
The Keith Medal was a prize awarded by the Royal Society of Edinburgh, Scotland's national academy, for a scientific paper published in the society's scientific journals, preference being given to a paper containing a discovery, either in mathematics or earth sciences. The Medal was inaugurated in 1827 as a result of a gift from Alexander Keith of Dunnottar, the first Treasurer of the Society. It was awarded quadrennially, alternately for a paper published in: Proceedings A (Mathematics) or Transactions (Earth and Environmental Sciences). The medal bears the head of John Napier of Merchiston. The medal is no longer awarded.

Stereoscope
A stereoscope is a device for viewing a stereoscopy, stereoscopic pair of separate images, depicting left-eye and right-eye views of the same scene, as a single three-dimensional image. A typical stereoscope provides each eye with a lens that makes the image seen through it appear larger and more distant and usually also shifts its apparent horizontal position, so that for a person with normal binocular depth perception the edges of the two images seemingly fuse into one "stereo window". In current practice, the images are prepared so that the scene appears to be beyond this virtual window, through which objects are sometimes allowed to protrude, but this was not always the custom. A divider or other view-limiting feature is usually provided to prevent each eye from being distracted by also seeing the image intended for the other eye. Most people can, with practice and some effort, view stereoscopic image pairs in 3D without the aid of a stereoscope, but the physiological dept ...
