National Security Advisor (United States)
The assistant to the president for national security affairs (APNSA), commonly referred to as the national security advisor (NSA),The National Security Advisor and Staff: p. 1. is a senior aide in the Executive Office of the President, based at the West Wing of the White House. The national security advisor serves as the principal advisor to the president of the United States on all national security issues. The national security advisor participates in meetings of the United States National Security Council, National Security Council (NSC) and usually chairs meetings of the principals committee of the NSC with the United States Secretary of State, secretary of state and United States Secretary of Defense, secretary of defense (those meetings not attended by the president).

Surface Warfare
Surface warfare is naval warfare involving surface ships. It is one of the four operational areas of naval warfare, the others being underwater warfare, aerial warfare, and information warfare. Surface warfare is the oldest and most basic form of naval warfare, though modern surface warfare doctrine originated in the mid-20th century. Description Modern surface warfare dates from the mid-20th century, when surface, air, and submarine warfare components were blended together as a tactical unit to achieve strategic objectives. In United States Navy doctrine, the two most important strategic objectives are interdiction and sea control. * Interdiction is the process of intercepting an enemy transiting through a location. For example, German naval objectives against Britain during World War II's Battle of the Atlantic were primarily focused on preventing ships from arriving intact with their cargoes. * Sea control is the dominance of force over a given area that prevents other n ...

Rudolf Mössbauer
Rudolf Ludwig Mössbauer (; 31 January 1929 – 14 September 2011) was a German physicist who shared the 1961 Nobel Prize in Physics with Robert Hofstadter for his discovery of the Mössbauer effect, which is the basis for Mössbauer spectroscopy. Career Mössbauer was born in Munich, where he also studied physics at the Technical University of Munich. He prepared his Diplom thesis in the Laboratory of Applied Physics of Heinz Maier-Leibnitz and graduated in 1955. He then went to the Max Planck Institute for Medical Research in Heidelberg. Since this institute, not part of a university, had no right to award a doctorate, Mössbauer remained under the auspices of Maier-Leibnitz, his official thesis advisor, when he passed his PhD exam in Munich in 1958. In his PhD, he discovered the ''recoilless nuclear fluorescence of gamma rays in 191 iridium,'' the Mössbauer effect. His fame grew immensely in 1960 when Robert Pound and Glen Rebka used this effect to prove the red sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nobel Laureate
The Nobel Prizes (, ) are awarded annually by the Royal Swedish Academy of Sciences, the Swedish Academy, the Karolinska Institutet, and the Norwegian Nobel Committee to individuals and organizations who make outstanding contributions in the fields of chemistry, physics, literature, peace, and physiology or medicine. They were established by the 1895 will of Alfred Nobel, which dictates that the awards should be administered by the Nobel Foundation. An additional prize in memory of Alfred Nobel was established in 1968 by Sveriges Riksbank (Sweden's central bank) for outstanding contributions to the field of economics. Each recipient, a Nobelist or '' laureate'', receives a gold medal, a diploma, and a sum of money which is decided annually by the Nobel Foundation. Prize Different organisations are responsible for awarding the individual prizes; the Royal Swedish Academy of Sciences awards the Prizes in Physics, Chemistry, and Economics; the Swedish Academy awards the ...

Mössbauer Effect
The Mössbauer effect, or recoilless nuclear resonance fluorescence, is a physical phenomenon discovered by Rudolf Mössbauer in 1958. It involves the resonant and recoil-free emission and absorption of gamma radiation by atomic nuclei bound in a solid. Its main application is in Mössbauer spectroscopy. In the Mössbauer effect, a narrow resonance for nuclear gamma emission and absorption results from the momentum of recoil being delivered to a surrounding crystal lattice rather than to the emitting or absorbing nucleus alone. When this occurs, no gamma energy is lost to the kinetic energy of recoiling nuclei at either the emitting or absorbing end of a gamma transition: emission and absorption occur at the same energy, resulting in strong, resonant absorption. History The emission and absorption of X-rays by gases had been observed previously. It was expected that a similar phenomenon would be found for gamma rays, which are created by nuclear transitions (as opposed to X-ra ...

Nuclear Physics
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons. Discoveries in nuclear physics have led to applications in many fields such as nuclear power, nuclear weapons, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Such applications are studied in the field of nuclear engineering. Particle physics evolved out of nuclear physics and the two fields are typically taught in close association. Nuclear astrophysics, the application of nuclear physics to astrophysics, is crucial in explaining the inner workings of stars and the origin of the chemical elements.

Information Awareness Office
The Information Awareness Office (IAO) was established by the United States Defense Advanced Research Projects Agency (DARPA) in January 2002 to bring together several DARPA projects focused on applying surveillance and information technology to track and monitor terrorists and other asymmetric warfare, asymmetric threats to U.S. national security by achieving "Total Information Awareness" (TIA). It was achieved by creating enormous computer databases to gather and store the personal information of everyone in the United States, including personal e-mails, social networks, credit card records, phone calls, medical records, and numerous other sources, without any requirement for a search warrant. The information was then analyzed for suspicious activities, connections between individuals, and "threats".Total Information Aware ...
