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 ...

Executive Order 9981
Executive Order 9981 was issued on July 26, 1948, by President Harry S. Truman. This executive order abolished discrimination "on the basis of race, color, religion or national origin" in the United States Armed Forces, and led to the re-integration of the services during the Korean War (1950–1953). It was a crucial event in the post-World War II civil rights movement and a major achievement of Truman's presidency. Before Executive Order 9981 Black Americans in the military worked under different rules that delayed their entry into combat. They had to wait four years before they could begin combat training while a white American would begin training within months of being qualified. The Air Corps was deliberately delaying the training of African Americans even though it needed more manpower (Survey and Recommendations). The Women's Army Corps (WAC) reenlistment program was open to black women, but overseas assignments were not. Black soldiers stationed in Britain during Wor ...

Dogfights (TV Series)
''Dogfights'' is a military aviation themed TV series depicting historical re-enactments of air-to-air combat that took place in World War I, World War II, the Korean War, and the Vietnam War, as well as smaller conflicts such as the Gulf War and the Six-Day War. The program consists of former fighter pilots sharing their stories of actual dogfights in which they took part, combined with computer-generated imagery (CGI) to give the viewer a better perspective of what it is like to engage in aerial combat. Historical documentary format The show has simulated not only air combat, but also surface sea combat, as in the case of Taffy 3's stand against the Japanese Center Force, and the Royal Navy's pursuit and destruction of the , which included the Bismarck being hit by torpedo bombers. These episodes have been cited as a source for several English Wikipedia articles, such as the Battle of Leyte Gulf. Simulated models include views from the cockpit, pilots visible through canopies, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Naval Research Laboratory
The United States Naval Research Laboratory (NRL) is the corporate research laboratory for the United States Navy and the United States Marine Corps. It was founded in 1923 and conducts basic scientific research, applied research, technological development and prototyping. The laboratory's specialties include plasma physics, space physics, materials science, and tactical electronic warfare. NRL is one of the first US government scientific R&D laboratories, having opened in 1923 at the instigation of Thomas Edison, and is currently under the Office of Naval Research. As of 2016, NRL was a United States Navy Working Capital Fund, Navy Working Capital Fund activity, which means it is not a line-item in the US Federal Budget. Instead of direct funding from Congress, all costs, including overhead, were recovered through sponsor-funded research projects. NRL's research expenditures were approximately $1 billion per year.

Harry Diamond Laboratories
The Harry Diamond Laboratories (HDL) was a research facility of the Ordnance Development Division of the National Bureau of Standards and later the US Army, most notable for its work on proximity fuzes in World War II. The organization was founded in 1940, but was not named after its first director Harry Diamond until 1962. HDL was one of seven Army laboratories merged to form the new Army Research Laboratory in 1992. History In 1940, concerned about increasing warfare abroad, the National Defense Research Committee organized a group of scientists and engineers into the Ordnance Development Division of the National Bureau of Standards (NBS), to develop fuzes for non-rotating (fin-stabilized) munitions such as bombs, rockets and mortar shells. Harry Diamond, a pioneer radio engineer, was given technical direction of the program, a position he held until his death in 1948. Proximity fuzes were first used in combat in January 1943, and the U.S. War Department later described the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Langley Research Center
The Langley Research Center (LaRC or NASA Langley), located in Hampton, Virginia, United States of America, is the oldest of NASA's field centers. It directly borders Langley Air Force Base and the Back River on the Chesapeake Bay. LaRC has focused primarily on aeronautical research, but has also tested space hardware such as the Apollo Lunar Module. In addition, many of the earliest high-profile space missions were planned and designed on-site. Langley was also considered a potential site for NASA's Manned Spacecraft Center prior to the eventual selection of Houston, Texas. Established in 1917 by the National Advisory Committee for Aeronautics (NACA), the research center devotes two-thirds of its programs to aeronautics and the rest to space. LaRC researchers use more than 40 wind tunnels to study and improve aircraft and spacecraft safety, performance, and efficiency. Between 1958 and 1963, when NASA (the successor agency to NACA) started Project Mercury, LaRC served as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Positronium
Positronium (Ps) is a system consisting of an electron and its antimatter, anti-particle, a positron, bound together into an exotic atom, specifically an onium. Unlike hydrogen, the system has no protons. The system is unstable: the two particles annihilate each other to predominantly produce two or three gamma-rays, depending on the relative spin states. The energy levels of the two particles are similar to that of the hydrogen atom (which is a bound state of a proton and an electron). However, because of the reduced mass, the frequency, frequencies of the spectral lines are less than half of those for the corresponding hydrogen lines. States The mass of positronium is 1.022 MeV, which is twice the electron mass minus the binding energy of a few eV. The lowest energy orbital state of positronium is 1S, and like with hydrogen, it has a hyperfine structure arising from the relative orientations of the spins of the electron and the positron. The Singlet state, ''singlet' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM System/370
The IBM System/370 (S/370) is a model range of IBM mainframe computers announced on June 30, 1970, as the successors to the System/360 family. The series mostly maintains backward compatibility with the S/360, allowing an easy migration path for customers; this, plus improved performance, were the dominant themes of the product announcement. In September 1990, the System/370 line was replaced with the System/390. Evolution The original System/370 line was announced on June 30, 1970, with first customer shipment of the Models 155 and 165 planned for February 1971 and April 1971 respectively. The 155 first shipped in January 1971. System/370 underwent several architectural improvements during its roughly 20-year lifetime. The following features mentioned in Principles of Operation are either optional on S/360 but standard on S/370, introduced with S/370 or added to S/370 after announcement. *Branch and Save *Channel Indirect Data Addressing *Channel-Set Switching *Clear I/O *Co ...
