In his last few years, Hofstadter became interested in astrophysics and applied his knowledge of scintillators to the design of the EGRET gamma-ray telescope of the Compton Gamma Ray Observatory named for fellow Nobel Laureate in Physics ( 1927 ), Arthur Holly Compton.

The first was Hubble Space Telescope ; the second was the Compton Gamma Ray Observatory, launched in 1991 ; and the last is the Spitzer Space Telescope.

The second of NASA's Great Observatories, the Compton Gamma Ray Observatory, operated for nine years before re-entering the Earth's atmosphere in 2000.

Examples of Observatories of the first type are RXTE, the Chandra X-ray Observatory and the Compton Gamma Ray Observatory.

The Rosemary Hill Observatory ( RHO ) started observing 3C 279 in 1971, and was further observed by the Compton Gamma Ray Observatory in 1991, when it was unexpectedly discovered to be one of the brightest gamma ray objects in the sky.

STS-37, the eighth flight of the Space Shuttle Atlantis, was a six-day mission with the primary objective of launching the Compton Gamma Ray Observatory ( GRO ), the second of the Great Observatories program which included the visible-spectrum Hubble Space Telescope, the Chandra X-ray Observatory and the infrared Spitzer Space Telescope.

GRO science instruments were Burst and Transient Source Experiment ( BATSE ), Imaging Compton Telescope ( COMPTEL ), Energetic Gamma Ray Experiment Telescope ( EGRET ) and Oriented Scintillation Spectrometer Experiment ( OSSE ).

Five months after deployment, NASA renamed the satellite the Arthur Holly Compton Gamma Ray Observatory, or Compton Observatory, after the Nobel Prize-winning physicist who did important work in gamma ray astronomy.

The primary mission objective was the successful deployment of the Chandra X-ray Observatory, the third of NASA's Great Observatories after Hubble Space Telescope and the Compton Gamma Ray Observatory.

The on-orbit TDRS network was rearranged and included two fully operational spacecraft occupying the TDRS East and West slots, one on-orbit fully functional spare, TDRS-1, which was nearly depleted having exceeded its planned lifetime, and the partially operational TDRS-3 spacecraft dedicated to supporting the Compton Gamma Ray Observatory and providing coverage an area that can't be seen by the other satellites known as the Zone of Exclusion.

The Compton Gamma Ray Observatory ( CGRO ) was a space observatory detecting light from 20 KeV to 30 GeV in Earth orbit from 1991 to 2000.

Gamma rays would Compton scatter in a forward detector module, where the interaction energy E < sub > 1 </ sub >, given to the recoil electron was measured, while the Compton scattered photon would then be caught in one of a second layer of scintillators to the rear, where its total energy, E < sub > 2 </ sub >, would be measured.

Twenty-two books were dedicated to him between 1936 and 1998, including works by H. E. Bates, Edmund Blunden, C. Day Lewis, Ray Bradbury, Diana Cooper, Eric Linklater, Compton Mackenzie, Anthony Powell and Leon Edel.

Grunsfeld studied binary pulsars and energetic x-ray and gamma ray sources using the NASA Compton Gamma Ray Observatory, x-ray astronomy satellites, radio telescopes, and optical telescopes including the NASA Hubble Space Telescope.

His leadership of the Compton Gamma Ray Observatory and the Swift Mission has led to new insights into the extreme physics of active galactic nuclei and gamma ray bursts ".

This nuclear astronomy was predicted in 1969 as a way to confirm explosive nucleosynthesis of the elements, and that prediction played an important role in the planning for NASA's successful Compton Gamma-Ray Observatory.

Stanford University's Department of Physics credits Hofstadter with being " one of the principal scientists who developed the Compton Observatory.

These were the International Space Station, the Hubble Space Telescope, the Chandra X-Ray Observatory, and the Compton Gamma-Ray Observatory.

CGRO was named after Dr. Arthur Holly Compton ( Washington University in St. Louis ), Nobel prize winner, for work involved with gamma ray physics.

* The gamma-ray sky map in the energy range 3 to 10 MeV as measured with the imaging Compton telescope COMPTEL on board CGRO ( 1994 )

* The Compton Gamma Ray Observatory ( CGRO ) primarily observed gamma rays, though it extended into hard x-rays as well.

The Gamma Ray Observatory ( GRO ), renamed Compton Gamma-Ray Observatory ( CGRO ), was designed to take advantage of the major advances in detector technology during the 1980s.

Brought to light by NASA's Gerald Fishman in 1994 in an article in Science, these so-called terrestrial gamma-ray flashes ( TGFs ) were observed by accident, while he was documenting instances of extraterrestrial gamma ray bursts observed by the Compton Gamma Ray Observatory ( CGRO ).

It stars Jack Warner as an England cricketer playing the last Test of his career, which is the last of an Ashes series ; the film contains cameo appearances from cricketers, including Jim Laker and Denis Compton, who were part of England's 1953 triumph.

The quantum mass of an electron, the Compton wavelength, can be determined through various forms of spectroscopy and is closely related to the Rydberg constant, the Bohr radius, and the classical electron radius.

The von Neumann description of quantum measurement of an observable A, when the system is prepared in a pure state ψ is the following ( note, however, that von Neumann's description dates back to the 1930s and is based on experiments as performed during that time – more specifically the Compton – Simon experiment ; it is not applicable to most present-day measurements within the quantum domain ):

Although these semiclassical models contributed to the development of quantum mechanics, many further experiments starting with Compton scattering of single photons by electrons, first observed in 1923, validated Einstein's hypothesis that light itself is quantized.

Although it is often claimed that the photoelectric and Compton effects require a quantum description of the EM field, this is now understood to be untrue, and proper proof of the quantum nature of radiation is now taken up into modern quantum optics as in the antibunching effect.

Incidentally the name given to this process of a photon interacting with an electron in this way is Compton Scattering.

An example is Compton scattering, with an electron and a photon undergoing elastic scattering.

A variation of the " A Chorus Line " instrumental was used as the basis of Tim Dog's debut single, the Ced Gee-produced " Fuck Compton ", which became a modest hit and is credited with helping to spark the East coast / West coast feud of the mid ' 90s.

Whether objects heavier than the Planck mass ( about the weight of a large bacterium ) have a de Broglie wavelength is theoretically unclear and experimentally unreachable ; above the Planck mass a particle's Compton wavelength would be smaller than the Planck length and its own Schwarzschild radius, a scale at which current theories of physics may break down or need to be replaced by more general ones.

Old Compton Street is now the core of Soho's gay village.

This is known as the Compton effect, and the resulting electrons produce an electric current that is known as the Compton current.

Within the range of gamma ray deposition, simple laws no longer hold as the air is ionised and there are other EMP effects, such as a radial electric field due to the separation of Compton electrons from air molecules, together with other complex phenomena.

The X-ray continuum can arise from bremsstrahlung, black-body radiation, synchrotron radiation, or what is called inverse Compton scattering of lower-energy photons by relativistic electrons, knock-on collisions of fast protons with atomic electrons, and atomic recombination, with or without additional electron transitions.

In Magic Man, Blaine is shown traveling across the country, entertaining unsuspecting pedestrians in New York City, Atlantic City, Dallas, San Francisco, Compton, and the Mojave Desert recorded by a small crew with handheld cameras.

Compton scattering is inelastic scattering of a photon by a free charged particle, usually electron.

Compton scattering is an example of inelastic scattering, because the wavelength of the scattered light is different from the incident radiation.
