Robert Rathbun Wilson
Robert Rathbun Wilson (March 4, 1914 – January 16, 2000) was an American physicist known for his work on the Manhattan Project during World War II, as a sculptor, and as an architect of the Fermi National Accelerator Laboratory (Fermilab), where he was the first director from 1967 to 1978. A graduate of the University of California, Berkeley (BA and PhD), Wilson received his doctorate under the supervision of Ernest Lawrence for his work on the development of the cyclotron at the Berkeley Radiation Laboratory. He subsequently went to Princeton University to work with Henry DeWolf Smyth on electromagnetic separation of the isotopes of uranium. In 1943, Wilson and many of his colleagues joined the Manhattan Project's Los Alamos Laboratory, where Wilson became the head of its Cyclotron Group (R-1), and later its Research (R) Division. After the war, Wilson briefly joined the faculty of Harvard University as an associate professor, then went to Cornell University as professor ...

Sculpture
Sculpture is the branch of the visual arts that operates in three dimensions. Sculpture is the three-dimensional art work which is physically presented in the dimensions of height, width and depth. It is one of the plastic arts. Durable sculptural processes originally used carving (the removal of material) and modelling (the addition of material, as clay), in stone, metal, ceramic art, ceramics, wood and other materials but, since Modernism, there has been an almost complete freedom of materials and process. A wide variety of materials may be worked by removal such as carving, assembled by welding or modelling, or Molding (process), moulded or Casting, cast. Sculpture in stone survives far better than works of art in perishable materials, and often represents the majority of the surviving works (other than pottery) from ancient cultures, though conversely traditions of sculpture in wood may have vanished almost entirely. However, most ancient sculpture was brightly painted, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Todd Seminary For Boys
The Todd Seminary for Boys (1848–1954) was an independent preparatory school located in Woodstock, Illinois, Woodstock, in the U.S. state of Illinois. From 1930 it was called the Todd School for Boys. Under headmaster Roger Hill from 1929, it became a progressive school that provided students including Orson Welles with a creative educational environment that emphasized practical experience over traditional academics. Only one building, Rogers Hall, remains from the original campus. History The Todd School for Boys was founded by Reverend Richard K. Todd, who brought from his native Vermont, the New England philosophy of "plain living and high thinking, and in harmony with Puritan traditions".''Todd Seminary for Boys Prospectus''. Woodstock, Illinois: Todd Seminary for Boys, 1922. Reverend Todd moved to Woodstock, Illinois, from Vermont in 1847 to be pastor of a newly formed Presbyterian Church.

American Bison
The American bison (''Bison bison'') is a species of bison native to North America. Sometimes colloquially referred to as American buffalo or simply buffalo (a different clade of bovine), it is one of two extant species of bison, alongside the European bison. Its historical range, by 9000 BC, is described as the great bison belt, a tract of rich grassland that ran from Alaska to the Gulf of Mexico, east to the Atlantic Seaboard (nearly to the Atlantic tidewater in some areas) as far north as New York, south to Georgia and, according to some sources, further south to Florida, with sightings in North Carolina near Buffalo Ford on the Catawba River as late as 1750. Once roaming in vast herds, the species nearly became extinct by a combination of commercial hunting and slaughter in the 19th century and introduction of bovine diseases from domestic cattle. With a population in excess of 60 million in the late 18th century, the species was culled down to just 541 animals by 1889. ...

Beauvais Cathedral
The Cathedral of Saint Peter of Beauvais (french: Cathédrale Saint-Pierre de Beauvais) is a Roman Catholic church in the northern town of Beauvais, Oise, France. It is the seat of the Bishop of Beauvais, Noyon and Senlis. The cathedral is in the Gothic style, and consists of a 13th-century choir, with an apse and seven polygonal apsidal chapels reached by an ambulatory, joined to a 16th-century transept. It has the highest Gothic choir in the world: (48.50 m) under vault. From 1569 to 1573 the cathedral of Beauvais was, with its tower of 153 meters, the highest human construction of the world. Its designers had the ambition to make it the largest gothic cathedral in France ahead of Amiens. Victim of two collapses, one in the 13th century, the other in the 16th century, it remains unfinished today; only the choir and the transept have been built. The planned nave of the cathedral was never constructed. The remnant of the previous 10th-century Romanesque cathedral, known as t ...

Synchrotron
A synchrotron is a particular type of cyclic particle accelerator, descended from the cyclotron, in which the accelerating particle beam travels around a fixed closed-loop path. The magnetic field which bends the particle beam into its closed path increases with time during the accelerating process, being ''synchronized'' to the increasing kinetic energy of the particles. The synchrotron is one of the first accelerator concepts to enable the construction of large-scale facilities, since bending, beam focusing and acceleration can be separated into different components. The most powerful modern particle accelerators use versions of the synchrotron design. The largest synchrotron-type accelerator, also the largest particle accelerator in the world, is the Large Hadron Collider (LHC) near Geneva, Switzerland, built in 2008 by the European Organization for Nuclear Research (CERN). It can accelerate beams of protons to an energy of 6.5 tera electronvolts (TeV or 1012 eV). Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isotopes Of Uranium
Uranium (92U) is a naturally occurring radioactive element that has no stable isotope. It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the Earth's crust. The decay product uranium-234 is also found. Other isotopes such as uranium-233 have been produced in breeder reactors. In addition to isotopes found in nature or nuclear reactors, many isotopes with far shorter half-lives have been produced, ranging from 214U to 242U (with the exceptions of 220U and 241U). The standard atomic weight of natural uranium is . Naturally occurring uranium is composed of three major isotopes, uranium-238 (99.2739–99.2752% natural abundance), uranium-235 (0.7198–0.7202%), and uranium-234 (0.0050–0.0059%). All three isotopes are radioactive (i.e., they are radioisotopes), and the most abundant and stable is uranium-238, with a half-life of (close to the age of the Earth). Uranium-238 is an alpha emitter, decayi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electromagnetic Separation
Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes. The use of the nuclides produced is varied. The largest variety is used in research (e.g. in chemistry where atoms of "marker" nuclide are used to figure out reaction mechanisms). By tonnage, separating natural uranium into enriched uranium and depleted uranium is the largest application. In the following text, mainly the uranium enrichment is considered. This process is crucial in the manufacture of uranium fuel for nuclear power plants, and is also required for the creation of uranium-based nuclear weapons. Plutonium-based weapons use plutonium produced in a nuclear reactor, which must be operated in such a way as to produce plutonium already of suitable isotopic mix or ''grade''. While different chemical elements can be purified through chemical processes, isotopes of the same element have nearly identical chemical properties, which makes this type of separation ...

Henry DeWolf Smyth
Henry DeWolf "Harry" Smyth (; May 1, 1898September 11, 1986) was an American physicist, diplomat, and bureaucrat. He played a number of key roles in the early development of Nuclear power, nuclear energy, as a participant in the Manhattan Project, a member of the U.S. Atomic Energy Commission (AEC), and U.S. ambassador to the International Atomic Energy Agency (IAEA). Educated at Princeton University and the University of Cambridge, he was a faculty member in Princeton's Department of Physics from 1924 to 1966. He chaired the department from 1935 to 1949. His early research was on the ionization of gases, but his interests shifted toward nuclear physics beginning in the mid-1930s. During World War II he was a member of the National Defense Research Committee's Uranium Committee and a consultant on the Manhattan Project. He wrote the Manhattan Project's first public official history, which came to be known as the Smyth Report. On the AEC from 1949 to 1954, Smyth initially argu ...
