Val Fitch
Val Logsdon Fitch (March 10, 1923 – February 5, 2015) was an American nuclear physicist who, with co-researcher James Cronin, was awarded the 1980 Nobel Prize in Physics for a 1964 experiment using the Alternating Gradient Synchrotron at Brookhaven National Laboratory that proved that certain subatomic reactions do not adhere to fundamental symmetry principles. Specifically, they proved, by examining the decay of K-mesons, that a reaction run in reverse does not retrace the path of the original reaction, which showed that the reactions of subatomic particles are not indifferent to time. Thus the phenomenon of CP violation was discovered. This demolished the faith that physicists had that natural laws were governed by symmetry. Born on a cattle ranch near Merriman, Nebraska, Fitch was drafted into the U.S. Army during World War II, and worked on the Manhattan Project at the Los Alamos Laboratory in New Mexico. He later graduated from McGill University, and completed his PhD in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subatomic
In physical sciences, a subatomic particle is a particle that composes an atom. According to the Standard Model of particle physics, a subatomic particle can be either a composite particle, which is composed of other particles (for example, a proton, neutron, or meson), or an elementary particle, which is not composed of other particles (for example, an electron, photon, or muon). Particle physics and nuclear physics study these particles and how they interact. Experiments show that light could behave like a stream of particles (called photons) as well as exhibiting wave-like properties. This led to the concept of wave–particle duality to reflect that quantum-scale behave like both particles and waves; they are sometimes called wavicles to reflect this. Another concept, the uncertainty principle, states that some of their properties taken together, such as their simultaneous position and momentum, cannot be measured exactly. The wave–particle duality has been shown to apply n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niels Bohr
Niels Henrik David Bohr (; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research. Bohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another. Although the Bohr model has been supplanted by other models, its underlying principles remain valid. He conceived the principle of complementarity: that items could be separately analysed in terms of contradictory properties, like behaving as a wave or a stream of particles. The notion of complementarity dominated Bohr's thinking in both science and philosophy. Bohr founded the Institute of Theoretical Physics at the University of Cope ...

Special Engineer Detachment
The Special Engineer Detachment (SED) was a US Army program that identified enlisted personnel with technical skills, such as machining, or who had some science education beyond high school. Those identified were organized into the Special Engineer Detachment, or SED. SED personnel began arriving at Los Alamos in October 1943. By August 1945, 1800 SED personnel worked at Los Alamos. These troops worked in all areas and activities of the Laboratory, including the Trinity Test, and were involved in overseas operations on Tinian Tinian ( or ; old Japanese name: 天仁安島, ''Tenian-shima'') is one of the three principal islands of the Commonwealth of the Northern Mariana Islands. Together with uninhabited neighboring Aguiguan, it forms Tinian Municipality, one of th ....

Army Specialized Training Program
The Army Specialized Training Program (ASTP) was a military training program instituted by the United States Army during World War II to meet wartime demands both for junior officers and soldiers with technical skills. Conducted at 227 American universities, it offered training in such fields as engineering, foreign languages, and medicine. The ASTP differed from the V-12 Navy College Training Program in producing technically trained personnel rather than officers as its primary goal, though recruits were told that they had the opportunity to become officers upon completion. The program was approved in September 1942 and implemented in December of that year. History Inception After the attack on Pearl Harbor sparked U.S. entry into the war, the Army suspended certain advanced elements of Reserve Officers' Training Corps (ROTC) training. This was a particularly problematic situation for the nation's numerous land-grant universities, whose constitutions include the legal agreemen ...

Valedictorian
Valedictorian is an academic title for the highest-performing student of a graduating class of an academic institution. The valedictorian is commonly determined by a numerical formula, generally an academic institution's grade point average (GPA) system, but other methods of selection may be used or factored in such as community service or extra-curricular activity. The term is an Anglicised derivation of the Latin ''vale dicere'' ("to say farewell"), historically rooted in the valedictorian's traditional role as the final speaker at the graduation ceremony commencement before the students receive their diplomas. The valedictory address, also known as the valediction, is generally considered a final farewell to classmates, before they disperse to pursue their individual paths after graduating. The term is not widely used or known outside the US, although some countries may award equivalent titles. In Australia, the title is sometimes awarded to a member of a graduating universit ...

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 ...
