David. H. Frisch
David Henry Frisch (March 12, 1918 – May 23, 1991) was an American physicist who helped develop the atom bomb in World War II and later became active in the disarmament movement. He was also the husband of Rose Epstein Frisch. Biography Born in New York, Frisch grew up in San Antonio and graduated from Princeton in 1940. He was a graduate assistant at the University of Wisconsin–Madison from 1940 to 1942, and then worked at Los Alamos from 1943 to 1945. After the war he moved to MIT, beginning as a research associate in 1946, obtained his PhD in 1947 and was appointed an assistant professor in 1948, associate professor in 1952 and full professor in 1958. He retired in 1988. Frisch was a fellow of the American Physical Society and of the American Academy of Arts and Sciences. He was the recipient of Fulbright, Guggenheim, Alfred P. Sloan and National Science Foundation research fellowships. Frisch served on the Physics Advisory Committee of the National Science ...

University Of Wisconsin–Madison
A university () is an educational institution, institution of higher education, higher (or Tertiary education, tertiary) education and research which awards academic degrees in several Discipline (academia), academic disciplines. Universities typically offer both undergraduate education, undergraduate and postgraduate education, postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation ...

New Hampshire
New Hampshire is a U.S. state, state in the New England region of the northeastern United States. It is bordered by Massachusetts to the south, Vermont to the west, Maine and the Gulf of Maine to the east, and the Canadian province of Quebec to the north. Of the 50 U.S. states, New Hampshire is the List of U.S. states and territories by area, fifth smallest by area and the List of U.S. states and territories by population, tenth least populous, with slightly more than 1.3 million residents. Concord, New Hampshire, Concord is the state capital, while Manchester, New Hampshire, Manchester is the largest city. New Hampshire's List of U.S. state mottos, motto, "Live Free or Die", reflects its role in the American Revolutionary War; its state nickname, nickname, "The Granite State", refers to its extensive granite formations and quarries.

Mount Washington (New Hampshire)
Mount Washington is the highest peak in the Northeastern United States at and the most topographically prominent mountain east of the Mississippi River. The mountain is notorious for its erratic weather. On the afternoon of April 12, 1934, the Mount Washington Observatory recorded a windspeed of at the summit, the world record from 1934 until 1996. Mount Washington still holds the record for highest measured wind speed not associated with a tornado or tropical cyclone. The mountain is located in the Presidential Range of the White Mountains, in Coös County, New Hampshire. The mountain is in several unincorporated townships, with the summit in the township of Sargent's Purchase. While nearly the whole mountain is in the White Mountain National Forest, an area of surrounding and including the summit is occupied by Mount Washington State Park. The Mount Washington Cog Railway ascends the western slope of the mountain, and the Mount Washington Auto Road climbs to the summ ...

Muons
A muon ( ; from the Greek letter mu (μ) used to represent it) is an elementary particle similar to the electron, with an electric charge of −1 '' e'' and a spin of , but with a much greater mass. It is classified as a lepton. As with other leptons, the muon is not thought to be composed of any simpler particles; that is, it is a fundamental particle. The muon is an unstable subatomic particle with a mean lifetime of , much longer than many other subatomic particles. As with the decay of the non-elementary neutron (with a lifetime around 15 minutes), muon decay is slow (by subatomic standards) because the decay is mediated only by the weak interaction (rather than the more powerful strong interaction or electromagnetic interaction), and because the mass difference between the muon and the set of its decay products is small, providing few kinetic degrees of freedom for decay. Muon decay almost always produces at least three particles, which must include an electron o ...

Time Dilation
In physics and relativity, time dilation is the difference in the elapsed time as measured by two clocks. It is either due to a relative velocity between them ( special relativistic "kinetic" time dilation) or to a difference in gravitational potential between their locations ( general relativistic gravitational time dilation). When unspecified, "time dilation" usually refers to the effect due to velocity. After compensating for varying signal delays due to the changing distance between an observer and a moving clock (i.e. Doppler effect), the observer will measure the moving clock as ticking slower than a clock that is at rest in the observer's own reference frame. In addition, a clock that is close to a massive body (and which therefore is at lower gravitational potential) will record less elapsed time than a clock situated further from the said massive body (and which is at a higher gravitational potential). These predictions of the theory of relativity have been repeatedl ...

Pugwash Conferences On Science And World Affairs
The Pugwash Conferences on Science and World Affairs is an international organization that brings together scholars and public figures to work toward reducing the danger of armed conflict and to seek solutions to global security threats. It was founded in 1957 by Joseph Rotblat and Bertrand Russell in Pugwash, Nova Scotia, Canada, following the release of the Russell–Einstein Manifesto in 1955. Rotblat and the Pugwash Conference jointly won the Nobel Peace Prize in 1995 for their efforts on nuclear disarmament.Russell's exclusion is explained because the Nobel Prizes are never awarded posthumously. International Student/Young Pugwash groups have existed since founder Cyrus Eaton's death in 1979. Origin of the Pugwash Conferences The Russell–Einstein Manifesto, released July 9, 1955, called for a conference for scientists to assess the dangers of weapons of mass destruction (then only considered to be nuclear weapons). Cyrus Eaton, an industrialist and philanthropist, offe ...

Fermi National Accelerator Laboratory
Fermi National Accelerator Laboratory (Fermilab), located just outside Batavia, Illinois, near Chicago, is a United States Department of Energy national laboratory specializing in high-energy particle physics. Since 2007, Fermilab has been operated by the Fermi Research Alliance, a joint venture of the University of Chicago, and the Universities Research Association (URA). Fermilab is a part of the Illinois Technology and Research Corridor. Fermilab's Main Injector, two miles (3.3 km) in circumference, is the laboratory's most powerful particle accelerator. The accelerator complex that feeds the Main Injector is under upgrade, and construction of the first building for the new PIP-II linear accelerator began in 2020. Until 2011, Fermilab was the home of the 6.28 km (3.90 mi) circumference Tevatron accelerator. The ring-shaped tunnels of the Tevatron and the Main Injector are visible from the air and by satellite. Fermilab aims to become a world center in neutri ...

National Science Foundation
The National Science Foundation (NSF) is an independent agency of the United States government that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National Institutes of Health. With an annual budget of about $8.3 billion (fiscal year 2020), the NSF funds approximately 25% of all federally supported basic research conducted by the United States' colleges and universities. In some fields, such as mathematics, computer science, economics, and the social sciences, the NSF is the major source of federal backing. The NSF's director and deputy director are appointed by the President of the United States and confirmed by the United States Senate, whereas the 24 president-appointed members of the National Science Board (NSB) do not require Senate confirmation. The director and deputy director are responsible for administration, planning, budgeting and day-to-day operations of the foundation, while t ...
