William Penney, Baron Penney
William George Penney, Baron Penney, (24 June 19093 March 1991) was an English mathematician and professor of mathematical physics at the Imperial College London and later the rector of Imperial College London. He had a leading role in the development of High Explosive Research, Britain's clandestine nuclear programme that started in 1942 during the Second World War which produced the first British atomic bomb in 1952. As the head of the British delegation working on the Manhattan Project at Los Alamos Laboratory, Penney initially carried out calculations to predict the damage effects generated by the blast wave of an atomic bomb. Upon returning home, Penney directed the British nuclear weapons directorate, codenamed Tube Alloys and directed scientific research at the Atomic Weapons Research Establishment which resulted in the first detonation of a British nuclear bomb in Operation Hurricane in 1952. After the test, Penney became chief advisor to the new United Kingd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Right Honourable
''The Right Honourable'' (abbreviation: The Rt Hon. or variations) is an honorific Style (form of address), style traditionally applied to certain persons and collective bodies in the United Kingdom, the former British Empire, and the Commonwealth of Nations. The term is predominantly used today as a style associated with the holding of certain senior public offices in the United Kingdom, Canada, New Zealand, and, to a lesser extent, Australia. ''Right'' in this context is an adverb meaning 'very' or 'fully'. Grammatically, ''The Right Honourable'' is an adjectival phrase which gives information about a person. As such, it is not considered correct to apply it in direct address, nor to use it on its own as a title in place of a name; but rather it is used in the Grammatical person, third person along with a name or noun to be modified. ''Right'' may be abbreviated to ''Rt'', and ''Honourable'' to ''Hon.'', or both. ''The'' is sometimes dropped in written abbreviated form, but is ...

Life Peer
In the United Kingdom, life peers are appointed members of the peerage whose titles cannot be inherited, in contrast to hereditary peers. Life peers are appointed by the monarch on the advice of the prime minister. With the exception of the Dukedom of Edinburgh awarded for life to Prince Edward in 2023, all life peerages conferred since 2009 have been created under the Life Peerages Act 1958 with the rank of baron, and entitle their holders to sit and vote in the House of Lords so long as they meet qualifications such as age and citizenship. The legitimate children of a life peer appointed under the Life Peerages Act 1958 are entitled to style themselves with the prefix "The Honourable", although they cannot inherit the peerage. Prior to 2009, life peers of baronial rank could also be created under the Appellate Jurisdiction Act 1876 for senior judges, referred to as Law Lords, with functions then taken over by the new Supreme Court. Before 1887 The Crown, as '' foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Detonation
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction. The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device. Nuclear explosions are used in nuclear weapons and nuclear testing. Nuclear explosions are extremely destructive compared to conventional (chemical) explosives, because of the vastly greater energy density of nuclear fuel compared to chemical explosives. They are often associated with mushroom clouds, since any large atmospheric explosion can create such a cloud. Nuclear explosions produce high levels of ionizing radiation and radioactive debris that is harmful to humans and can cause moderate to severe skin burns, eye damage, radiation sickness, radiation-induced cancer and possible death depending ...

Atomic Bomb
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission or atomic bomb) or a combination of fission and fusion reactions (thermonuclear weapon), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. Nuclear bombs have had yields between 10 tons (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). Yields in the low kilotons can devastate cities. A thermonuclear weapon weighing as little as can release energy equal to more than 1.2 megatons of TNT (5.0 PJ). Apart from the blast, effects of nuclear weapons include firestorms, extreme heat and ionizing radiation, radioactive nuclear fallout, an electromagnetic pulse, and a radar blackout. The first nuclear weapons were developed by the Allied Manhattan Project during World War II. Their production continues to require a large scientific and industrial complex, primari ...

Blast Wave
In fluid dynamics, a blast wave is the increased pressure and flow resulting from the deposition of a large amount of energy in a small, very localised volume. The flow field can be approximated as a lead shock wave, followed by a similar subsonic flow field. In simpler terms, a blast wave is an area of pressure expanding supersonically outward from an explosive core. It has a leading shock front of compressed gases. The blast wave is followed by a blast wind of negative gauge pressure, which sucks items back in towards the center. The blast wave is harmful especially to objects very close to the center or at a location of constructive interference. High explosives that detonate generate blast waves. Sources High-order explosives (HE) are more powerful than low-order explosives (LE). HE detonate to produce a defining supersonic over-pressurization shock wave. Sources of HE include trinitrotoluene (TNT), C-4, Semtex, nitroglycerin, and ammonium nitrate fuel oil (ANFO). LE deflagra ...

Mathematical Optimization
Mathematical optimization (alternatively spelled ''optimisation'') or mathematical programming is the selection of a best element, with regard to some criteria, from some set of available alternatives. It is generally divided into two subfields: discrete optimization and continuous optimization. Optimization problems arise in all quantitative disciplines from computer science and engineering to operations research and economics, and the development of solution methods has been of interest in mathematics for centuries. In the more general approach, an optimization problem consists of maxima and minima, maximizing or minimizing a Function of a real variable, real function by systematically choosing Argument of a function, input values from within an allowed set and computing the Value (mathematics), value of the function. The generalization of optimization theory and techniques to other formulations constitutes a large area of applied mathematics. Optimization problems Opti ...

Manhattan Project
The Manhattan Project was a research and development program undertaken during World War II to produce the first nuclear weapons. It was led by the United States in collaboration with the United Kingdom and Canada. From 1942 to 1946, the project was directed by Major General Leslie Groves of the United States Army Corps of Engineers, U.S. Army Corps of Engineers. Nuclear physicist J. Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the bombs. The Army program was designated the Manhattan District, as its first headquarters were in Manhattan; the name gradually superseded the official codename, Development of Substitute Materials, for the entire project. The project absorbed its earlier British counterpart, Tube Alloys, and subsumed the program from the American civilian Office of Scientific Research and Development. The Manhattan Project employed nearly 130,000 people at its peak and cost nearly US$2 billion (equivalent to about $ b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Contribution To The Manhattan Project
Britain initiated the first research project to design an atomic bomb in 1941. Building on this work, Britain prompted the United States to recognise how important this type of research was, helped the U.S. to start the Manhattan Project in 1942, and supplied crucial expertise and materials that contributed to the project's successful completion in time to influence the end of the Second World War. Following the discovery of nuclear fission in uranium, scientists Rudolf Peierls and Otto Frisch at the University of Birmingham calculated, in March 1940, that the critical mass of a metallic sphere of pure uranium-235 was as little as , and would explode with the power of thousands of tons of dynamite. The Frisch–Peierls memorandum prompted Britain to create an atomic bomb project, known as Tube Alloys. Mark Oliphant, an Australian physicist working in Britain, was instrumental in making the results of the British MAUD Report known in the United States in 1941 by a visit in pers ...

Second World War
World War II or the Second World War (1 September 1939 – 2 September 1945) was a World war, global conflict between two coalitions: the Allies of World War II, Allies and the Axis powers. World War II by country, Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks in World War II, Tanks and Air warfare of World War II, aircraft played major roles, enabling the strategic bombing of cities and delivery of the Atomic bombings of Hiroshima and Nagasaki, first and only nuclear weapons ever used in war. World War II is the List of wars by death toll, deadliest conflict in history, causing World War II casualties, the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Allied-occupied Germany, Germany, Allied-occupied Austria, Austria, Occupation of Japan, Japan, a ...

Rector Of Imperial College London
The president of Imperial College London is the highest academic official of Imperial College London. The president is the chief executive and is elected by the council of the college and chairman of the senate. The position is currently held by Hugh Brady, who succeeded Alice Gast in August 2022. In 2012 the responsibilities were separated into two posts, the ''president & rector'' (later simplified to president) whose duty is to "promote Imperial's position as a global university" and '' provost'' who is "responsible for advancing and delivering the College's core academic mission - education, research and translation." From 2013, Alice Gast served as president & rector, while James Stirling became the first provost of Imperial College London in August 2013. The president's residence is a large house on Queen's Gate, at the southwest corner of the college's campus in South Kensington, London.

Mathematical Physics
Mathematical physics is the development of mathematics, mathematical methods for application to problems in physics. The ''Journal of Mathematical Physics'' defines the field as "the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories". An alternative definition would also include those mathematics that are inspired by physics, known as physical mathematics. Scope There are several distinct branches of mathematical physics, and these roughly correspond to particular historical parts of our world. Classical mechanics Applying the techniques of mathematical physics to classical mechanics typically involves the rigorous, abstract, and advanced reformulation of Newtonian mechanics in terms of Lagrangian mechanics and Hamiltonian mechanics (including both approaches in the presence of constraints). Both formulations are embodied in analytical mechanics and lead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medal Of Freedom
The Presidential Medal of Freedom is the highest civilian award of the United States, alongside the Congressional Gold Medal. It is an award bestowed by decision of the president of the United States to "any person recommended to the President for award of the Medal or any person selected by the President upon his own initiative", and was created to recognize people who have made "an especially meritorious contribution to (1) the security or national interests of the United States, or (2) world peace, or (3) cultural or other significant public or private endeavors." The award is not limited to U.S. citizens, and, while it is a civilian award, it can also be awarded to military personnel and worn on the uniform. It was established in 1963 by President John F. Kennedy, superseding the Medal of Freedom that was initially established by President Harry S. Truman in 1945 to honor civilian service. Occasionally, the medal award is further denoted as, "with distinction." There are no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
