Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

James Chadwick
Sir James Chadwick, (20 October 1891 – 24 July 1974) was an English physicist who was awarded the 1935 Nobel Prize in Physics for his discovery of the neutron in 1932. In 1941, he wrote the final draft of the MAUD Report, which inspired the U.S. government to begin serious atom bomb research efforts. He was the head of the British team that worked on the Manhattan Project during World War II. He was knighted in Britain in 1945 for his achievements in physics. Chadwick graduated from the Victoria University of Manchester in 1911, where he studied under Ernest Rutherford (known as the "father of nuclear physics"). At Manchester, he continued to study under Rutherford until he was awarded his MSc in 1913. The same year, Chadwick was awarded an 1851 Research Fellowship from the Royal Commission for the Exhibition of 1851. He elected to study beta radiation under Hans Geiger in Berlin. Using Geiger's recently developed Geiger counter, Chadwick was able to dem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GLEEP
GLEEP, which stood for Graphite Low Energy Experimental Pile, was a long-lived experimental nuclear reactor in Oxfordshire, England. Run for the first time on August 15, 1947, it was the first reactor to operate in western Europe. It was built at the Atomic Energy Research Establishment, a former Royal Air Force airfield, near Harwell in Oxfordshire (then in Berkshire), in an aircraft hangar. It was a graphite moderated, air-cooled reactor and used 11,500 natural uranium fuel aluminium-clad rods inserted into 676 horizontal fuel channels. With a normal power output of just 3 kilowatts, it was initially used for investigations into reactor design and operation, and later for the calibration of instruments for measuring neutron flux. It had an exceptionally long life for a reactor of 43 years, being shut down in 1990. The fuel was removed in 1994 and the control rods and external equipment the following year. A project to completely dismantle it was started in 2003 and completed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Van De Graaff Generator
A Van de Graaff generator is an electrostatic generator which uses a moving belt to accumulate electric charge on a hollow metal globe on the top of an insulated column, creating very high electric potentials. It produces very high voltage direct current (DC) electricity at low current levels. It was invented by American physicist Robert J. Van de Graaff in 1929. The potential difference achieved by modern Van de Graaff generators can be as much as 5 megavolts. A tabletop version can produce on the order of 100 kV and can store enough energy to produce visible electric sparks. Small Van de Graaff machines are produced for entertainment, and for physics education to teach electrostatics; larger ones are displayed in some science museums. The Van de Graaff generator was originally developed as a particle accelerator for physics research, as its high potential can be used to accelerate subatomic particles to great speeds in an evacuated tube. It was the most powerful type of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Cockcroft
Sir John Douglas Cockcroft, (27 May 1897 – 18 September 1967) was a British physicist who shared with Ernest Walton the Nobel Prize in Physics in 1951 for splitting the atomic nucleus, and was instrumental in the development of nuclear power.

RAF Harwell
Royal Air Force Harwell or more simply RAF Harwell is a former Royal Air Force station, near the village of Harwell, located south east of Wantage, Oxfordshire and north west of Reading, Berkshire, England. The site is now the Harwell Science and Innovation Campus which includes the Rutherford Appleton Laboratory. History The airfield was built by John Laing & Son Ltd at the junction of three parishes in 1935. The bulk lay within Chilton parish; about a third was in East Hendred; and the smallest portion was in Harwell. The first Commanding Officer, upon being asked what the name of the new airfield should be, responded that it should be named after the parish in which his house lay – and this happened to be Harwell. From its opening in February 1937 until March 1944, various bomber squadrons were stationed at the airfield. On the outbreak of the Second World War, it became part of No. 38 Group RAF, initially used for leaflet missions over France using Vickers ...

Ernest Lawrence
Ernest Orlando Lawrence (August 8, 1901 – August 27, 1958) was an American nuclear physicist and winner of the Nobel Prize in Physics in 1939 for his invention of the cyclotron. He is known for his work on uranium-isotope separation for the Manhattan Project, as well as for founding the Lawrence Berkeley National Laboratory and the Lawrence Livermore National Laboratory. A graduate of the University of South Dakota and University of Minnesota, Lawrence obtained a PhD in physics at Yale in 1925. In 1928, he was hired as an associate professor of physics at the University of California, Berkeley, becoming the youngest full professor there two years later. In its library one evening, Lawrence was intrigued by a diagram of an accelerator that produced high-energy particles. He contemplated how it could be made compact, and came up with an idea for a circular accelerating chamber between the poles of an electromagnet. The result was the first cyclotron. Lawrence went on to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark Oliphant
Sir Marcus Laurence Elwin Oliphant, (8 October 1901 – 14 July 2000) was an Australian physicist and humanitarian who played an important role in the first experimental demonstration of nuclear fusion and in the development of nuclear weapons. Born and raised in Adelaide, South Australia, Oliphant graduated from the University of Adelaide in 1922. He was awarded an 1851 Exhibition Scholarship in 1927 on the strength of the research he had done on mercury, and went to England, where he studied under Sir Ernest Rutherford at the University of Cambridge's Cavendish Laboratory. There, he used a particle accelerator to fire heavy hydrogen nuclei (deuterons) at various targets. He discovered the respective nuclei of helium-3 (helions) and of tritium (tritons). He also discovered that when they reacted with each other, the particles that were released had far more energy than they started with. Energy had been liberated from inside the nucleus, and he realised that this was a re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
