Glen A. Rebka
Glen Anderson Rebka Jr. (September 19, 1931, CincinnatiJanuary 13, 2015, Laramie) was an American physicist. Biography Rebka attained a doctorate 1961 at Harvard, where he began study in 1953. Starting from 1961 he was at Yale University and starting from 1970 at the University of Wyoming, where he was from 1983 to 1991 department head of the physics faculty and is since 1997 professor emeritus. In addition to his academic career he did much work as an experimental elementary-particle physicist at Los Alamos National Laboratory. At the University of Wyoming he built up the astrophysics faculty. In 1960 Robert Pound carried out together with his assistant Glen Rebka an experiment, the Pound–Rebka experiment, using the Mössbauer effect to measure the gravitational redshift of the radiation from a gamma source in the gravitation field of planet Earth. Pound and Rebka used at Harvard University the Jefferson tower, which is only 22.6 meters tall. The work was part of Rebka's thesis ...

Cincinnati
Cincinnati ( ) is a city in the U.S. state of Ohio and the county seat of Hamilton County. Settled in 1788, the city is located at the northern side of the confluence of the Licking and Ohio rivers, the latter of which marks the state line with Kentucky. The city is the economic and cultural hub of the Cincinnati metropolitan area. With an estimated population of 2,256,884, it is Ohio's largest metropolitan area and the nation's 30th-largest, and with a city population of 309,317, Cincinnati is the third-largest city in Ohio and 64th in the United States. Throughout much of the 19th century, it was among the top 10 U.S. cities by population, surpassed only by New Orleans and the older, established settlements of the United States eastern seaboard, as well as being the sixth-most populous city from 1840 until 1860. As a rivertown crossroads at the junction of the North, South, East, and West, Cincinnati developed with fewer immigrants and less influence from Europe than Ea ...

Gravitation
In physics, gravity () is a fundamental interaction which causes mutual attraction between all things with mass or energy. Gravity is, by far, the weakest of the four fundamental interactions, approximately 1038 times weaker than the strong interaction, 1036 times weaker than the electromagnetic force and 1029 times weaker than the weak interaction. As a result, it has no significant influence at the level of subatomic particles. However, gravity is the most significant interaction between objects at the macroscopic scale, and it determines the motion of planets, stars, galaxies, and even light. On Earth, gravity gives weight to physical objects, and the Moon's gravity is responsible for sublunar tides in the oceans (the corresponding antipodal tide is caused by the inertia of the Earth and Moon orbiting one another). Gravity also has many important biological functions, helping to guide the growth of plants through the process of gravitropism and influencing the circul ...

Physics Experiments
Physics is the natural science that studies matter, its Elementary particle, fundamental constituents, its motion and behavior through Spacetime, space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental science, scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first und ...

Stalin states: "We are fifty or a hundred years behind the advanced countries. We must make good this distance in ten years. Either we do it, or they will crush us." The first five-year plan in the Soviet Union is intensified, for the industrialization and collectivization of agriculture. * February 10 †...

Gamma Radiation
A gamma ray, also known as gamma radiation (symbol γ or \gamma), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves, typically shorter than those of X-rays. With frequencies above 30 exahertz (), it imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation ''gamma rays'' based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power. Gamma rays from radioactive decay are in the energy range from a few kiloelectronvolts (keV) to approximately 8 megaelectronvolts (MeV), corresponding to the typical energy levels in nuclei with reasonably long lifeti ...

Laramie, Wyoming
Laramie is a city in and the county seat of Albany County, Wyoming, United States. The population was estimated 32,711 in 2019, making it the third-largest city in Wyoming after Cheyenne and Casper. Located on the Laramie River in southeastern Wyoming, the city is north west of Cheyenne, at the junction of Interstate 80 and U.S. Route 287. Laramie was settled in the mid-19th century along the Union Pacific Railroad line, which crosses the Laramie River at Laramie. It is home to the University of Wyoming, WyoTech, and a branch of Laramie County Community College. Laramie Regional Airport serves Laramie. The ruins of Fort Sanders, an army fort predating Laramie, lie just south of the city along Route 287. Located in the Laramie Valley between the Snowy Range and the Laramie Range, the city draws outdoor enthusiasts with its abundance of outdoor activities. In 2011, Laramie was named as one of the best cities in which to retire by ''Money Magazine'', which cited its scenic loc ...
