David Schramm (astrophysicist)
David Norman Schramm (October 25, 1945 – December 19, 1997) was an American astrophysicist and educator, and one of the world's foremost experts on the Big Bang theory. Schramm was a pioneer in establishing particle astrophysics as a vibrant research field. He was particularly well known for the study of Big Bang nucleosynthesis and its use as a probe of dark matter (both baryonic and non-baryonic) and of neutrinos. He also made important contributions to the study of cosmic rays, supernova explosions, heavy-element nucleosynthesis, and nuclear astrophysics generally. Biography David Schramm was born in St. Louis, Missouri and earned his master's degree in physics from the Massachusetts Institute of Technology in 1967, where he was also a member of the Delta Upsilon fraternity and the wrestling squad. He earned a Ph.D in physics at Caltech in 1971 under Willy Fowler and Gerry Wasserburg. After a brief time as faculty at the University of Texas at Austin where he als ...

Cosmic Rays
Cosmic rays are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, and from distant galaxies. Upon impact with Earth's atmosphere, cosmic rays produce showers of secondary particles, some of which reach the surface, although the bulk is deflected off into space by the magnetosphere or the heliosphere. Cosmic rays were discovered by Victor Hess in 1912 in balloon experiments, for which he was awarded the 1936 Nobel Prize in Physics. Direct measurement of cosmic rays, especially at lower energies, has been possible since the launch of the first satellites in the late 1950s. Particle detectors similar to those used in nuclear and high-energy physics are used on satellites and space probes for research into cosmic rays. Data from the Fermi Space Telescope (2013) have been interpreted as evidence ...

American Astronomical Society
The American Astronomical Society (AAS, sometimes spoken as "double-A-S") is an American society of professional astronomers and other interested individuals, headquartered in Washington, DC. The primary objective of the AAS is to promote the advancement of astronomy and closely related branches of science, while the secondary purpose includes enhancing astronomy education and providing a political voice for its members through lobbying and grassroots activities. Its current mission is to enhance and share humanity's scientific understanding of the universe as a diverse and inclusive astronomical community. History The society was founded in 1899 through the efforts of George Ellery Hale. The constitution of the group was written by Hale, George Comstock, Edward Morley, Simon Newcomb and Edward Charles Pickering. These men, plus four others, were the first Executive Council of the society; Newcomb was the first president. The initial membership was 114. The AAS name of the so ...

William Alfred Fowler
William Alfred Fowler ( ) was an American nuclear physicist, later astrophysicist, who, with Subrahmanyan Chandrasekhar, won the 1983 Nobel Prize in Physics. He is known for his theoretical and experimental research into nuclear reactions within stars and the energy elements produced in the process and was one of the authors of the influential BFH paper. Early life On , Fowler was born in Pittsburgh. Fowler's parents were John MacLeod Fowler and Jennie Summers Watson. Fowler was the eldest of his siblings, Arthur and Nelda. The family moved to Lima, Ohio, a steam railroad town, when Fowler was two years old. Growing up near the Pennsylvania Railroad yard influenced Fowler's interest in locomotives. In 1973, he travelled to the Soviet Union just to observe the steam engine that powered the Trans-Siberian Railway plying the nearly route that connects Khabarovsk and Moscow. Education In 1933, Fowler graduated from the Ohio State University, where he was a member of the Tau Kap ...

Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through 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 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 understanding the basic laws of physic ...
