Leslie Fleetwood Bates
Leslie Fleetwood Bates, CBE, FRS (7 March 1897 – 20 January 1978) was an English physicist known for his contributions to ferromagnetism. He was Lancashire-Spencer Professor of Physics at the University of Nottingham from 1936 until his retirement in 1964. Early life, undergraduate studies and the War Born on 7 March 1897 in Kingswood, Bristol, Bates was the eldest son of William Fleetwood Bates, originally from Bletchley, Buckinghamshire, who worked as a clerk in a boot manufacturing company, and his wife, Henrietta Anne, ''née'' Pearce, from Kingswood, Bristol. Despite being raised an Anglican, he decided to attend the Moravian Church from the age of 7. He attended Hanham Road Boys' School until 1909, when he started at the Merchant Venturers' Secondary School with the aid of a bursary and scholarship. In 1913, he won a City of Bristol Scholarship to study physics at the University of Bristol; he was influenced by his father's pacifism and did not enlist to fight in World ...

Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service. It was established on 4 June 1917 by King George V and comprises five classes across both civil and military divisions, the most senior two of which make the recipient either a knight if male or dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order. Recommendations for appointments to the Order of the British Empire were originally made on the nomination of the United Kingdom, the self-governing Dominions of the Empire (later Commonwealth) and the Viceroy of India. Nominations continue today from Commonwealth countries that participate in recommending British honours. Most Commonwealth countries ceased recommendations for appointments to the Order of the British Empire when they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiographer
Radiographers, also known as radiologic technologists, diagnostic radiographers and medical radiation technologists are healthcare professionals who specialize in the imaging of human anatomy for the diagnosis and treatment of pathology. Radiographers are infrequently, and almost always erroneously, known as ''x-ray technicians.'' In countries that use the title ''radiologic technologist'' they are often informally referred to as ''techs'' in the clinical environment; this phrase has emerged in popular culture such as television programmes. The term ''radiographer'' can also refer to a ''therapeutic radiographer'', also known as a radiation therapist. Radiographers are allied health professionals who work in both public healthcare and private healthcare and can be physically located in any setting where appropriate diagnostic equipment is located, most frequently in hospitals. The practice varies from country to country and can even vary between hospitals in the same country ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinium
Actinium is a chemical element with the symbol Ac and atomic number 89. It was first isolated by Friedrich Oskar Giesel in 1902, who gave it the name ''emanium''; the element got its name by being wrongly identified with a substance André-Louis Debierne found in 1899 and called actinium. Actinium gave the name to the actinide series, a group of 15 similar elements between actinium and lawrencium in the periodic table. Together with polonium, radium, and radon, actinium was one of the first non-primordial radioactive elements to be isolated. A soft, silvery-white radioactive metal, actinium reacts rapidly with oxygen and moisture in air forming a white coating of actinium oxide that prevents further oxidation. As with most lanthanides and many actinides, actinium assumes oxidation state +3 in nearly all its chemical compounds. Actinium is found only in traces in uranium and thorium ores as the isotope 227Ac, which decays with a half-life of 21.772 years, predominantly e ...

Thorium
Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90. Thorium is silvery and tarnishes black when it is exposed to air, forming thorium dioxide; it is moderately soft and malleable and has a high melting point. Thorium is an electropositive actinide whose chemistry is dominated by the +4 oxidation state; it is quite reactive and can ignite in air when finely divided. All known thorium isotopes are unstable. The most stable isotope, 232Th, has a half-life of 14.05 billion years, or about the age of the universe; it decays very slowly via alpha decay, starting a decay chain named the thorium series that ends at stable 208 Pb. On Earth, thorium and uranium are the only significantly radioactive elements that still occur naturally in large quantities as primordial elements. Thorium is estimated to be over three times as abundant as uranium in the Earth's crust, and is chiefly refined from monazite sands as a by-product of extracti ...

Radium
Radium is a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) upon exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are radioactive, the most stable isotope being radium-226 with a half-life of 1600 years. When radium decays, it emits ionizing radiation as a by-product, which can excite fluorescent chemicals and cause radioluminescence. Radium, in the form of radium chloride, was discovered by Marie and Pierre Curie in 1898 from ore mined at Jáchymov. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later. Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1911. In nature, radium is found ...

Alpha Particle
Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways. Alpha particles are named after the first letter in the Greek alphabet, α. The symbol for the alpha particle is α or α2+. Because they are identical to helium nuclei, they are also sometimes written as or indicating a helium ion with a +2 charge (missing its two electrons). Once the ion gains electrons from its environment, the alpha particle becomes a normal (electrically neutral) helium atom . Alpha particles have a net spin of zero. Due to the mechanism of their production in standard alpha radioactive decay, alpha particles generally have a kinetic energy of about 5 MeV, and a velocity in the vicinity of 4% of the speed of light. (See discussion below for the limits of these figures in alpha decay.) They are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernest Rutherford
Ernest Rutherford, 1st Baron Rutherford of Nelson, (30 August 1871 – 19 October 1937) was a New Zealand physicist who came to be known as the father of nuclear physics. ''Encyclopædia Britannica'' considers him to be the greatest experimentalist since Michael Faraday (1791–1867). Apart from his work in his homeland, he spent a substantial amount of his career abroad, in both Canada and the United Kingdom. In early work, Rutherford discovered the concept of radioactive half-life, the radioactive element radon, and differentiated and named alpha and beta radiation. This work was performed at McGill University in Montreal, Quebec, Canada. It is the basis for the Nobel Prize in Chemistry he was awarded in 1908 "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances", for which he was the first Oceanian Nobel laureate, and the first to perform the awarded work in Canada. In 1904, he was elected as a member to the Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trinity College, Cambridge
Trinity College is a constituent college of the University of Cambridge.

Doctor Of Philosophy
A Doctor of Philosophy (PhD, Ph.D., or DPhil; Latin: or ') is the most common Academic degree, degree at the highest academic level awarded following a course of study. PhDs are awarded for programs across the whole breadth of academic fields. Because it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a Thesis, dissertation, and defend their work before a panel of other experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title ''Doctor (title), Doctor'' (often abbreviated "Dr" or "Dr.") with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society. Those who teach at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Department Of Scientific And Industrial Research (United Kingdom)
The Department of Scientific and Industrial Research was a department of the British Government responsible for the organisation, development, and encouragement of scientific and industrial research. At the outbreak of the First World War "Britain found ... it was dangerously dependent on enemy industries". At the request of the Board of Trade, the Board of Education prepared a White Paper under the chairmanship of Sir William McCormick. The DSIR was set up to fill the roles that the White Paper specified: "to finance worthy research proposals, to award research fellowships and studentships n universities and to encourage the development of research associations in private industry and research facilities in university science departments. trapidly assumed a key role in coordinating government aid to university research. It maintained these roles until 1965. The annual budget during its first year, 1915, was £1,000,000. History Before the twentieth century, the government was ...

Arthur Prince Chattock
Arthur Prince Chattock, FRS (14 August 1860 – 1 July 1934) was a British physicist. Career Chattock was educated at University College School and University College London. After a short time as an electrical engineer for Siemens he returned to University College, London to study under George Carey Foster. In 1885 he succeeded Silvanus P. Thompson at University College, Bristol as demonstrator in Physics. Chattock spent two years (1887-9) in Liverpool with Oliver Lodge where in February 1888 he worked on key experiments towards the understanding of radio waves. Later he returned to Bristol and took up the chair of Physics in 1893. Chattock had to leave the university in 1910 as it struggled with its new university status, the acting head of the physics department role being taken by Arthur Mannering Tyndall. After leaving Chattock became a chicken farmer in Crowcombe, Somerset. But Tyndall invited Chattock back after the war in 1919 where he carried out definitive experi ...
