York
York is a cathedral city with Roman origins, sited at the confluence of the rivers Ouse and Foss in North Yorkshire, England. It is the historic county town of Yorkshire. The city has many historic buildings and other structures, such as a minster, castle, and city walls. It is the largest settlement and the administrative centre of the wider City of York district. The city was founded under the name of Eboracum in 71 AD. It then became the capital of the Roman province of Britannia Inferior, and later of the kingdoms of Deira, Northumbria, and Scandinavian York. In the Middle Ages, it became the northern England ecclesiastical province's centre, and grew as a wool-trading centre. In the 19th century, it became a major railway network hub and confectionery manufacturing centre. During the Second World War, part of the Baedeker Blitz bombed the city; it was less affected by the war than other northern cities, with several historic buildings being gutted and restore ...

Sir William Crookes
Sir William Crookes (; 17 June 1832 – 4 April 1919) was a British chemist and physicist who attended the Royal College of Chemistry, now part of Imperial College London, and worked on spectroscopy. He was a pioneer of vacuum tubes, inventing the Crookes tube which was made in 1875. This was a foundational discovery that eventually changed the whole of chemistry and physics. He is credited with discovering the element thallium, announced in 1861, with the help of spectroscopy. He was also the first to describe the spectrum of terrestrial helium, in 1865. Crookes was the inventor of the Crookes radiometer but did not discern the true explanation of the phenomenon he detected. Crookes also invented a 100% ultraviolet blocking sunglass lens. For a time, he was interested in spiritualism and became president of the Society for Psychical Research. Biography Crookes' life was one of unbroken scientific activity that extended over sixty-seven years. He was considered remarkable for ...

British Institute Of Radiology
The British Institute of Radiology (BIR) is a radiology society and charity based in London, United Kingdom. It is the oldest institute of its kind in the world, forming on 2 April 1897. History The society can be traced back to two separate institutes, "The X-Ray Society" in April, 1897, and "The Röntgen Society"; both were formed in the wake of the discovery of X-rays by Wilhelm Röntgen in 1895. The latter was founded by Dr John Macintyre in 1897. He had been the first person in Britain to use X-rays, using equipment created by William Thomson, Lord Kelvin at Glasgow Royal Infirmary on 5 February 1896. The formalisation of the BIR occurred in 1927 upon the merger of the two societies. The BIR became a registered charity in 1963. Among other publications, the BIR publishes several journals including the ''British Journal of Radiology'' (BJR), and ''Dentomaxillofacial Radiology'' (the official journal of the International Association of Dentomaxillofacial Radiology, IADMF ...

Clinical Society Of London
The Clinical Society of London was founded in London in 1868 and merged in 1907 with the Royal Society of Medicine. The founding of the Clinical Society was mainly due to Drs. Edward Headlam Greenhow and John Burdon Sanderson who convened a meeting to discuss the formation of a society "''for the cultivation and promotion of practical medicine and surgery by the collection of cases, especially such as bear upon undetermined questions in pathology and therapeutics''". Sir Thomas Watson was appointed first president and some 110 members recruited and the first general meeting held on 10 January 1868. Ordinary meetings were then held twice a month from October to May, at which short papers were submitted and discussed. The specific medical cases discussed were drawn from all branches of medicine. An annual general meeting was held at which officers were elected. Presidents served for two years. In 1896 the society invited Professor Silvanus Phillips Thompson to demonstrate the new x-r ...

Coaxial Cable
Coaxial cable, or coax (pronounced ) is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric ( insulating material); many coaxial cables also have a protective outer sheath or jacket. The term ''coaxial'' refers to the inner conductor and the outer shield sharing a geometric axis. Coaxial cable is a type of transmission line, used to carry high-frequency electrical signals with low losses. It is used in such applications as telephone trunk lines, broadband internet networking cables, high-speed computer data busses, cable television signals, and connecting radio transmitters and receivers to their antennas. It differs from other shielded cables because the dimensions of the cable and connectors are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a transmission line. Coaxial cable was used in the first (1858) and followin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Röntgen
Wilhelm Conrad Röntgen (; ; 27 March 184510 February 1923) was a German mechanical engineer and physicist, who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays, an achievement that earned him the inaugural Nobel Prize in Physics in 1901.Novelize, Robert.

Royal Institution Christmas Lectures
The Royal Institution Christmas Lectures are a series of lectures on a single topic each, which have been held at the Royal Institution in London each year since 1825, missing 1939–1942 because of the Second World War. The lectures present scientific subjects to a general audience, including young people, in an informative and entertaining manner. Michael Faraday initiated the Christmas Lecture series in 1825, at a time when organised education for young people was scarce. Faraday presented nineteen series of lectures in all. History The Royal Institution's Christmas Lectures were first held in 1825, and have continued on an annual basis since then except for four years during the Second World War. They have been hosted each year at the Royal Institution itself, except in 1929 and between 2005–2006, each time due to refurbishment of the building. They were created by Michael Faraday, who later hosted the lecture season on nineteen occasions. The Nobel laureate Sir William B ...

University College, Bristol
University College, Bristol was an educational institution which existed from 1876 to 1909. It was the predecessor institution to the University of Bristol, which gained a royal charter in 1909. During its time the college mainly served the middle classes of Bristol, and catered for young men who had entered a family business and needed a greater understanding of scientific topics. Origins The history of University College, Bristol and ultimately the University of Bristol can be traced as far back as 1872 and the attempts of John Percival, a local educationalist and headmaster of Clifton College, to press for the creation of a college. Percival was a supporter of the education of women, having founded an Association for the Promotion of the Higher Education of Women in 1868, and an Association for the Promotion of Evening Classes a year later. Percival's strong Christian religious views (he later became a bishop) influenced his views on education, in that he believed that ...
