Robert F. Bacher
Robert Fox Bacher (August 31, 1905November 18, 2004) was an American nuclear physicist and one of the leaders of the Manhattan Project. Born in Loudonville, Ohio, Bacher obtained his undergraduate degree and doctorate from the University of Michigan, writing his 1930 doctoral thesis under the supervision of Samuel Goudsmit on the Zeeman effect of the hyperfine structure of atomic levels. After graduate work at the California Institute of Technology (Caltech) and the Massachusetts Institute of Technology (MIT), he accepted a job at Columbia University. In 1935 he accepted an offer from Hans Bethe to work with him at Cornell University in Ithaca, New York. It was there that Bacher collaborated with Bethe on his book ''Nuclear Physics. A: Stationary States of Nuclei'' (1936), the first of three books that would become known as the "Bethe Bible". In December 1940, Bacher joined the Radiation Laboratory at MIT, although he did not immediately cease his research at Cornell ...

Loudonville, Ohio
Loudonville is a village in Ashland and Holmes counties in the U.S. state of Ohio. The population was 2,641 at the 2010 census. Loudonville is nicknamed the "Canoe Capital of Ohio" for the many canoe liveries along the Mohican River. It is also home to Mohican State Park and Mohican-Memorial State Forest and Landoll's Mohican Castle. History Loudonville was laid out in 1814 by James Louden Priest, and named for him. A post office called Loudonville has been in operation since 1820. Loudonville was the long-time (1913–96) home of The Flxible Company, a manufacturer of motorcycle sidecars, commercial cars (hearses, ambulances, and flower cars), intercity coaches, and city-transit coaches. During World War II, Flxible interrupted its normal production and built instead a variety of war goods. A part of the former Flxible plant was in use as a parts depot and service point for the Motor Coach Industries until December 5, 2014, when all production was shut down. The town of Lo ...

Professor Emeritus
''Emeritus'' (; female: ''emerita'') is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In the description of deceased professors emeritus listed at U.S. universities, the title ''emeritus'' is replaced by indicating the years of their appointmentsThe Proto ...

Provost (education)
A provost is a senior academic administrator. At many institutions of higher education, they are the chief academic officer, a role that may be combined with being deputy to the chief executive officer. They may also be the chief executive officer of a university, of a branch campus of a university, or of a college within a university. Duties, role, and selection The specific duties and areas of responsibility for a provost vary from one institution to another, but usually include supervision and oversight of curricular, instructional, and research affairs. The various deans of a university's schools, colleges, or faculties typically report to the provost, or jointly to them and the institution's chief executive officer—which office may be called president, chancellor, vice-chancellor or rector. Likewise do the heads of the various interdisciplinary units and academic support functions (such as libraries, student services, the registrar, admissions, and information ...

President's Science Advisory Committee
The President's Science Advisory Committee (PSAC) was created on November 21, 1957, by President of the United States Dwight D. Eisenhower, as a direct response to the Soviet launching of the Sputnik 1 and Sputnik 2 satellites. PSAC was an upgrade and move to the White House of the Science Advisory Committee (SAC) established in 1951 by President Harry S. Truman, as part of the Office of Defense Mobilization (ODM). Its purpose was to advise the president on scientific matters in general, and those related to defense issues in particular. Eisenhower appointed James R. Killian as PSAC's first director. In 1961, President John F. Kennedy renamed the agency the Office of Science and Technology (OST). This lasted until Richard Nixon's administration in 1973. In 1976 the Office of Science and Technology Policy was established. First report The first report of the newly formed Science Advisory Committee, commonly known as the Killian Report (February 14, 1955, officially "Meeting ...

Los Alamos National Laboratory
Los Alamos National Laboratory (often shortened as Los Alamos and LANL) is one of the sixteen research and development laboratories of the United States Department of Energy (DOE), located a short distance northwest of Santa Fe, New Mexico, in the American southwest. Best known for its central role in helping develop the first atomic bomb, LANL is one of the world's largest and most advanced scientific institutions. Los Alamos was established in 1943 as Project Y, a top-secret site for designing nuclear weapons under the Manhattan Project during World War II.The site was variously called Los Alamos Laboratory and Los Alamos Scientific Laboratory. Chosen for its remote yet relatively accessible location, it served as the main hub for conducting and coordinating nuclear research, bringing together some of the world's most famous scientists, among them numerous Nobel Prize winners. The town of Los Alamos, directly north of the lab, grew extensively through this period. A ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Robert Oppenheimer
J. Robert Oppenheimer (; April 22, 1904 – February 18, 1967) was an American theoretical physicist. A professor of physics at the University of California, Berkeley, Oppenheimer was the wartime head of the Los Alamos Laboratory and is often credited as the "father of the atomic bomb" for his role in the Manhattan Project—the World War II undertaking that developed the first nuclear weapons. Oppenheimer was among those who observed the Trinity test in New Mexico, where the first atomic bomb was successfully detonated on July 16, 1945. He later remarked that the explosion brought to mind words from the '' Bhagavad Gita'': "Now I am become Death, the destroyer of worlds." In August 1945, the weapons were used in the atomic bombings of Hiroshima and Nagasaki. After the war ended, Oppenheimer became chairman of the influential General Advisory Committee of the newly created United States Atomic Energy Commission. He used that position to lobby for international control of nuc ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

General Electric
General Electric Company (GE) is an American multinational conglomerate founded in 1892, and incorporated in New York state and headquartered in Boston. The company operated in sectors including healthcare, aviation, power, renewable energy, digital industry, additive manufacturing and venture capital and finance, but has since divested from several areas, now primarily consisting of the first four segments. In 2020, GE ranked among the Fortune 500 as the 33rd largest firm in the United States by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE – Irving Langmuir (1932) and Ivar Giaever (1973) – have been awarded the Nobel Prize. On November 9, 2021, the company announced it would divide itself into three investment-grade public companies. On July 18, 2022, GE unveiled the brand names of the companies it wi ...

Radar
Radar is a detection system that uses radio waves to determine the distance ('' ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution ...

Cadmium
Cadmium is a chemical element with the symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in groups 3 through 11. Cadmium and its congeners in group 12 are often not considered transition metals, in that they do not have partly filled ''d'' or ''f'' electron shells in the elemental or common oxidation states. The average concentration of cadmium in Earth's crust is between 0.1 and 0.5 parts per million (ppm). It was discovered in 1817 simultaneously by Stromeyer and Hermann, both in Germany, as an impurity in zinc carbonate. Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production. Cadmium was used for a long time as a corrosion-resistant plating on steel, and cadmium compounds are used as red, ora ...

Neutron Cross Section
In nuclear physics, the concept of a neutron cross section is used to express the likelihood of interaction between an incident neutron and a target nucleus. The neutron cross section σ can be defined as the area in cm2 for which the number of neutron-nuclei reactions taking place is equal to the product of the number of incident neutrons that would pass through the area and the number of target nuclei. In conjunction with the neutron flux, it enables the calculation of the reaction rate, for example to derive the thermal power of a nuclear power plant. The standard unit for measuring the cross section is the barn, which is equal to 10−28 m2 or 10−24 cm2. The larger the neutron cross section, the more likely a neutron will react with the nucleus. An isotope (or nuclide) can be classified according to its neutron cross section and how it reacts to an incident neutron. Nuclides that tend to absorb a neutron and either decay or keep the neutron in its nucleus are neutron ...
