Hoquiam, Washington
–
Hoquiam is a city in Grays Harbor County, Washington, United States. The town borders the city of Aberdeen at Myrtle Street, with Hoquiam to the west, the two cities share a common economic history in lumbering and exporting, but Hoquiam has maintained its independent identity. Aberdeen is more populated, but the two cities have a rivalry, especially in high school sports. Hoquiam was incorporated on May 21,1890 and its name comes from a Native-American word meaning hungry for wood, so named from the great amount of driftwood at the mouth of the Hoquiam River. In 2010 the population was 8,726, one of the first logging operations in Hoquiam was established by Ed Campbell in 1872. About 10 years later, Captain Asa M. Simpson, a Pacific Coast mariner and businessman in the industry from San Francisco. In 1881, Simpson sent his manager, George Emerson, to Hoquiam to establish a mill there, by September 1882, the Simpson mill was producing its first lumber products. In 1913, Frank J. Shields became the new manager at the mill at Hoquiam, the extension of the railroad from Aberdeen to Hoquiam, beginning in 1898, contributed to the continued importance of logging and lumber in Hoquiam. The importance of logging and related products continued to be relevant to Hoquiam’s economy, and in 1927, a year later, a Pennsylvania company- the Hammerhill Paper Company- became interested in Grays Harbor Pulp Company. When the Pennsylvania company bought stock in the Grays Harbor Pulp Company, in 1936, the Grays Harbor Pulp and Paper Company merged with Rayonier Incorporated, a company which used a certain kind of pulp to produce rayon. In 1907, Hoquiam was home to Industrial Workers of the World Industrial Union No.276. According to the United States Census Bureau, the city has an area of 15.60 square miles. Hoquiam experiences a Mediterranean climate that borders closely on an oceanic climate, outside of the mild and dry summer season, rainfall is generally very high and monthly totals of over 20 inches are not unknown. Snowfall is rare and indeed does not fall many years, however in the winter of 1964/1965 as much as 40.8 inches of snow fell in two storms. As of the census of 2010, there were 8,726 people,3,480 households, the population density was 967.4 inhabitants per square mile. There were 3,938 housing units at a density of 436.6 per square mile. The racial makeup of the city was 85. 5% White,0. 8% African American,3. 9% Native American,1. 1% Asian,0. 2% Pacific Islander,4. 2% from other races, and 4. 2% from two or more races. Hispanic or Latino of any race were 9. 5% of the population,30. 7% of all households were made up of individuals and 13. 6% had someone living alone who was 65 years of age or older

Pasadena /ˌpæsəˈdiːnə/ is a city in Los Angeles County, California, United States. As of 2013, the population of Pasadena was 139,731. Pasadena is the ninth-largest city in Los Angeles County, Pasadena was incorporated on June 19,1886, becoming one of the first cities be incorporated in what is now Los Angeles County, the only one being incorporated earlier being its namesake. It is one of the cultural centers of the San Gabriel Valley. The city is known for hosting the annual Rose Bowl football game, the original inhabitants of Pasadena and surrounding areas were members of the Native American Hahamog-na tribe, a branch of the Tongva Nation. They spoke the Tongva language and had lived in the Los Angeles Basin for thousands of years, Tongva dwellings lined the Arroyo Seco in present day Pasadena and south to where it joins the Los Angeles River and along other natural waterways in the city. The native people lived in thatched, dome-shape lodges and they lived on a diet of acorn meal, seeds and herbs, venison, and other small animals. They traded for fish with the coastal Tongva. They made cooking vessels from steatite soapstone from Catalina Island, the trail has been in continuous use for thousands of years. An arm of the trail is still in use in what is now known as Salvia Canyon. When the Spanish occupied the Los Angeles Basin they built the San Gabriel Mission and renamed the local Tongva people Gabrielino Indians, today, several bands of Tongva people live in the Los Angeles area. The Rancho comprised the lands of todays communities of Pasadena, Altadena, before the annexation of California in 1848, the last of the Mexican owners was Manuel Garfias who retained title to the property after statehood in 1850. Garfias sold sections of the property to the first Anglo settlers to come into the area, Dr. Benjamin Eaton, the father of Fred Eaton, much of the property was purchased by Benjamin Wilson, who established his Lake Vineyard property in the vicinity. Wilson, known as Don Benito to the local Indians, also owned the Rancho Jurupa and was mayor of Los Angeles and he was the grandfather of WWII General George S. Patton, Jr. and the namesake of Mount Wilson. Berry was an asthmatic and claimed that he had his best three nights sleep at Rancho San Pascual, to keep the find a secret, Berry code-named the area Muscat after the grape that Wilson grew. To raise funds to bring the company of people to San Pascual, Berry formed the Southern California Orange and Citrus Growers Association and sold stock in it. The newcomers were able to purchase a portion of the property along the Arroyo Seco and on January 31,1874. As a gesture of good will, Wilson added 2,000 acres of then-useless highland property, at the time, the Indiana Colony was a narrow strip of land between the Arroyo Seco and Fair Oaks Avenue

The University of Washington, commonly referred to as simply Washington, UW, or informally U-Dub, is a public flagship research university in Seattle, Washington, United States. Founded in 1861, Washington is one of the oldest universities on the West Coast, the university has three campuses, the oldest and largest in the University District of Seattle and two others in Tacoma and Bothell. Washington is a member of the Association of American Universities and is ranked among the top 15 universities in the world by a variety of international publications. In athletics, the university competes in the NCAA Division I Pac-12 Conference and its athletic teams are called the Huskies. Seattle was one of several settlements in the mid to late 19th century vying for primacy in the new Washington Territory, in 1854, territorial governor Isaac Stevens recommended the establishment of a university in Washington. Several prominent Seattle-area residents, chief among them Methodist preacher Daniel Bagley and they convinced early founder of Seattle and member of the territorial legislature Arthur A. Denny of the importance of Seattle winning the school. When no site emerged, the legislature, encouraged by Denny, in 1861, scouting began for an appropriate 10 acres site in Seattle to serve as the campus for a new university. Arthur and Mary Denny donated eight acres, and fellow pioneers Edward Lander and Charlie and this tract was bounded by 4th and 6th Avenues on the west and east and Union and Seneca Streets on the north and south. UW opened on November 4,1861, as the Territorial University of Washington, the following year, the legislature passed articles incorporating the University and establishing a Board of Regents. The school struggled initially, closing three times, in 1863 for lack of students, and again in 1867 and 1876 due to shortage of funds. However, Clara Antoinette McCarty Wilt became the first graduate of UW in 1876 when she graduated from UW with a degree in science. By the time Washington entered the Union in 1889, both Seattle and the University had grown substantially, enrollment increased from 30 students to nearly 300, and the relative isolation of the campus had given way to encroaching development. A special legislative committee headed by UW graduate Edmond Meany was created to find a new campus able to serve the growing student population. The committee selected a site on Union Bay northeast of downtown, the university relocated from downtown to the new campus in 1895, moving into the newly built Denny Hall. The regents tried and failed to sell the old campus, the University still owns what is now called the Metropolitan Tract. In the heart of the city, it is among the most valuable pieces of estate in Seattle. The original Territorial University building was torn down in 1908 and its former site houses the Fairmont Olympic Hotel. The sole surviving remnants of UWs first building are four 24-foot, white, hand-fluted cedar and they were salvaged by Edmond S. Meany—one of the Universitys first graduates and the former head of the history department

The California Institute of Technology is a private doctorate-granting university located in Pasadena, California, United States. The vocational and preparatory schools were disbanded and spun off in 1910, the university is one among a small group of Institutes of Technology in the United States which is primarily devoted to the instruction of technical arts and applied sciences. Caltech has six divisions with strong emphasis on science and engineering, managing $332 million in 2011 in sponsored research. Its 124-acre primary campus is located approximately 11 mi northeast of downtown Los Angeles, first-year students are required to live on campus, and 95% of undergraduates remain in the on-campus House System at Caltech. Although Caltech has a tradition of practical jokes and pranks. The Caltech Beavers compete in 13 intercollegiate sports in the NCAA Division IIIs Southern California Intercollegiate Athletic Conference, Caltech is frequently cited as one of the worlds best universities. There are 112 faculty members who have elected to the United States National Academies. In addition, numerous faculty members are associated with the Howard Hughes Medical Institute as well as NASA, according to a 2015 Pomona College study, Caltech ranked number one in the U. S. for the percentage of its graduates who go on to earn a PhD. Caltech started as a school founded in Pasadena in 1891 by local businessman and politician Amos G. Throop. The school was known successively as Throop University, Throop Polytechnic Institute, the vocational school was disbanded and the preparatory program was split off to form an independent Polytechnic School in 1907. At a time when research in the United States was still in its infancy, George Ellery Hale. He joined Throops board of trustees in 1907, and soon began developing it and he engineered the appointment of James A. B. Scherer, a literary scholar untutored in science but a capable administrator and fund raiser, scherer persuaded retired businessman and trustee Charles W. Gates to donate $25,000 in seed money to build Gates Laboratory, the first science building on campus. In 1910, Throop moved to its current site, arther Fleming donated the land for the permanent campus site. The promise of Throop attracted physical chemist Arthur Amos Noyes from MIT to develop the institution and assist in establishing it as a center for science, with the onset of World War I, Hale organized the National Research Council to coordinate and support scientific work on military problems. This institution, with its able investigators and excellent research laboratories, through the National Research Council, Hale simultaneously lobbied for science to play a larger role in national affairs, and for Throop to play a national role in science. During the course of the war, Hale, Noyes and Millikan worked together in Washington on the NRC, subsequently, they continued their partnership in developing Caltech. Under the leadership of Hale, Noyes and Millikan, Caltech grew to prominence in the 1920s

Uncertainty principle
–
The formal inequality relating the standard deviation of position σx and the standard deviation of momentum σp was derived by Earle Hesse Kennard later that year and by Hermann Weyl in 1928. Heisenberg offered such an effect at the quantum level as a physical explanation of quantum uncertainty. Thus, the uncertainty principle actually states a fundamental property of quantum systems, since the uncertainty principle is such a basic result in quantum mechanics, typical experiments in quantum mechanics routinely observe aspects of it. Certain experiments, however, may deliberately test a particular form of the uncertainty principle as part of their research program. These include, for example, tests of number–phase uncertainty relations in superconducting or quantum optics systems, applications dependent on the uncertainty principle for their operation include extremely low-noise technology such as that required in gravitational wave interferometers. The uncertainty principle is not readily apparent on the scales of everyday experience. So it is helpful to demonstrate how it applies to more easily understood physical situations, two alternative frameworks for quantum physics offer different explanations for the uncertainty principle. The wave mechanics picture of the uncertainty principle is more visually intuitive, a nonzero function and its Fourier transform cannot both be sharply localized. In matrix mechanics, the formulation of quantum mechanics, any pair of non-commuting self-adjoint operators representing observables are subject to similar uncertainty limits. An eigenstate of an observable represents the state of the wavefunction for a certain measurement value, for example, if a measurement of an observable A is performed, then the system is in a particular eigenstate Ψ of that observable. According to the de Broglie hypothesis, every object in the universe is a wave, the position of the particle is described by a wave function Ψ. The time-independent wave function of a plane wave of wavenumber k0 or momentum p0 is ψ ∝ e i k 0 x = e i p 0 x / ℏ. In the case of the plane wave, | ψ |2 is a uniform distribution. In other words, the position is extremely uncertain in the sense that it could be essentially anywhere along the wave packet. The figures to the right show how with the addition of many plane waves, in mathematical terms, we say that ϕ is the Fourier transform of ψ and that x and p are conjugate variables. Adding together all of these plane waves comes at a cost, namely the momentum has become less precise, One way to quantify the precision of the position and momentum is the standard deviation σ. Since | ψ |2 is a probability density function for position, the precision of the position is improved, i. e. reduced σx, by using many plane waves, thereby weakening the precision of the momentum, i. e. increased σp. Another way of stating this is that σx and σp have a relationship or are at least bounded from below

Medal for Merit
–
Since the proclamation of an emergency by the President on September 8,1939. The first medals were awarded to John C, garand and Albert Hoyt Taylor on March 28,1944. The first person to receive this medal who was not an American citizen was Edgar Sengier, Sengier was awarded the Medal for Merit on April 9,1946. The second foreign civilian to receive the medal was the Canadian spymaster William Stephenson in November 1946, Stephenson had the code name Intrepid during World War II. Some writers consider Stephenson to be one of the real life inspirations for the fictitious character James Bond, all proposed awards were considered by the Medal for Merit Board, consisting of three members appointed by the President, of whom one was appointed as the Chairman of the Board. The last medal of this type was awarded in 1952 after a delay in processing

Physicist
–
A physicist is a scientist who has specialized knowledge in the field of physics, the exploration of the interactions of matter and energy across the physical universe. A physicist is a scientist who specializes or works in the field of physics, physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists can also apply their knowledge towards solving real-world problems or developing new technologies, some physicists specialize in sectors outside the science of physics itself, such as engineering. The study and practice of physics is based on a ladder of discoveries. Many mathematical and physical ideas used today found their earliest expression in ancient Greek culture and Asian culture, the bulk of physics education can be said to flow from the scientific revolution in Europe, starting with the work of Galileo and Kepler in the early 1600s. New knowledge in the early 21st century includes an increase in understanding physical cosmology. The term physicist was coined by William Whewell in his 1840 book The Philosophy of the Inductive Sciences, many physicist positions require an undergraduate degree in applied physics or a related science or a Masters degree like MSc, MPhil, MPhys or MSci. In a research oriented level, students tend to specialize in a particular field, Physics students also need training in mathematics, and also in computer science and programming. For being employed as a physicist a doctoral background may be required for certain positions, undergraduate students like BSc Mechanical Engineering, BSc Electrical and Computer Engineering, BSc Applied Physics. etc. With physics orientation are chosen as research assistants with faculty members, the highest honor awarded to physicists is the Nobel Prize in Physics, awarded since 1901 by the Royal Swedish Academy of Sciences. The three major employers of career physicists are academic institutions, laboratories, and private industries, with the largest employer being the last, physicists in academia or government labs tend to have titles such as Assistants, Professors, Sr. /Jr. As per the American Institute for Physics, some 20% of new physics Ph. D. s holds jobs in engineering development programs, while 14% turn to computer software, a majority of physicists employed apply their skills and training to interdisciplinary sectors. For industry or self-employment. and also in science and programming. Hence a majority of Physics bachelors degree holders are employed in the private sector, other fields are academia, government and military service, nonprofit entities, labs and teaching

Princeton University is a private Ivy League research university in Princeton, New Jersey, United States. The institution moved to Newark in 1747, then to the current site nine years later, Princeton provides undergraduate and graduate instruction in the humanities, social sciences, natural sciences, and engineering. The university has ties with the Institute for Advanced Study, Princeton Theological Seminary, Princeton has the largest endowment per student in the United States. The university has graduated many notable alumni, two U. S. Presidents,12 U. S. Supreme Court Justices, and numerous living billionaires and foreign heads of state are all counted among Princetons alumni body. New Light Presbyterians founded the College of New Jersey in 1746 in order to train ministers, the college was the educational and religious capital of Scots-Irish America. In 1754, trustees of the College of New Jersey suggested that, in recognition of Governors interest, gov. Jonathan Belcher replied, What a name that would be. In 1756, the moved to Princeton, New Jersey. Its home in Princeton was Nassau Hall, named for the royal House of Orange-Nassau of William III of England, following the untimely deaths of Princetons first five presidents, John Witherspoon became president in 1768 and remained in that office until his death in 1794. During his presidency, Witherspoon shifted the focus from training ministers to preparing a new generation for leadership in the new American nation. To this end, he tightened academic standards and solicited investment in the college, in 1812, the eighth president the College of New Jersey, Ashbel Green, helped establish the Princeton Theological Seminary next door. The plan to extend the theological curriculum met with approval on the part of the authorities at the College of New Jersey. Today, Princeton University and Princeton Theological Seminary maintain separate institutions with ties that include such as cross-registration. Before the construction of Stanhope Hall in 1803, Nassau Hall was the sole building. The cornerstone of the building was laid on September 17,1754, during the summer of 1783, the Continental Congress met in Nassau Hall, making Princeton the countrys capital for four months. The class of 1879 donated twin lion sculptures that flanked the entrance until 1911, Nassau Halls bell rang after the halls construction, however, the fire of 1802 melted it. The bell was then recast and melted again in the fire of 1855, James McCosh took office as the colleges president in 1868 and lifted the institution out of a low period that had been brought about by the American Civil War. McCosh Hall is named in his honor, in 1879, the first thesis for a Doctor of Philosophy Ph. D. was submitted by James F. Williamson, Class of 1877. In 1896, the officially changed its name from the College of New Jersey to Princeton University to honor the town in which it resides

Thesis
–
A thesis or dissertation is a document submitted in support of candidature for an academic degree or professional qualification presenting the authors research and findings. In some contexts, the thesis or a cognate is used for part of a bachelors or masters course, while dissertation is normally applied to a doctorate, while in other contexts. The term graduate thesis is used to refer to both masters theses and doctoral dissertations. The required complexity or quality of research of a thesis or dissertation can vary by country, university, or program, the word dissertation can at times be used to describe a treatise without relation to obtaining an academic degree. The term thesis is used to refer to the general claim of an essay or similar work. The term thesis comes from the Greek θέσις, meaning something put forth, Dissertation comes from the Latin dissertātiō, meaning path. A thesis may be arranged as a thesis by publication or a monograph, with or without appended papers, an ordinary monograph has a title page, an abstract, a table of contents, comprising the various chapters, and a bibliography or a references section. They differ in their structure in accordance with the different areas of study. In a thesis by publication, the chapters constitute an introductory, Dissertations normally report on a research project or study, or an extended analysis of a topic. The structure of the thesis or dissertation explains the purpose, the research literature which impinges on the topic of the study, the methods used. Degree-awarding institutions often define their own style that candidates have to follow when preparing a thesis document. Other applicable international standards include ISO2145 on section numbers, ISO690 on bibliographic references, some older house styles specify that front matter uses a separate page-number sequence from the main text, using Roman numerals. They therefore avoid the traditional separate number sequence for front matter, however, strict standards are not always required. Most Italian universities, for example, have only general requirements on the size and the page formatting. A thesis or dissertation committee is a committee that supervises a students dissertation, the committee members are doctors in their field and have the task of reading the dissertation, making suggestions for changes and improvements, and sitting in on the defense. Sometimes, at least one member of the committee must be a professor in a department that is different from that of the student, all the dissertation referees must already have achieved at least the academic degree that the candidate is trying to reach. At English-speaking Canadian universities, writings presented in fulfillment of undergraduate coursework requirements are normally called papers, a longer paper or essay presented for completion of a 4-year bachelors degree is sometimes called a major paper. High-quality research papers presented as the study of a postgraduate consecutive bachelor with Honours or Baccalaureatus Cum Honore degree are called thesis

In a 1948 paper dealing with relativistic shock waves, he introduced a relativistic generalization of the Rankine-Hugoniot jump conditions across a shock, which is now known as the Taub Adiabat. He also introduced the Taub–NUT space in general relativity, Taub earned his doctorate at Princeton University in 1935, under the direction of the prominent relativist Howard P. Robertson. At Princeton, Taub was also influenced by Oswald Veblen, in 1948, Abe Taub went to the University of Illinois as the chief mathematician associated with a project to build a computer based on von Neumanns plans. The computer, called ORDVAC, was completed in 1952 and delivered to the Aberdeen Proving Grounds, a second copy of the computer, ILLIAC I, remained at Illinois and was the prototype for several other computers.

Mathematician
–
A mathematician is someone who uses an extensive knowledge of mathematics in his or her work, typically to solve mathematical problems. Mathematics is concerned with numbers, data, quantity, structure, space, models, one of the earliest known mathematicians was Thales of Miletus, he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, the number of known mathematicians grew when Pythagoras of Samos established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was All is number. It was the Pythagoreans who coined the term mathematics, and with whom the study of mathematics for its own sake begins, the first woman mathematician recorded by history was Hypatia of Alexandria. She succeeded her father as Librarian at the Great Library and wrote works on applied mathematics. Because of a dispute, the Christian community in Alexandria punished her, presuming she was involved, by stripping her naked. Science and mathematics in the Islamic world during the Middle Ages followed various models and it was extensive patronage and strong intellectual policies implemented by specific rulers that allowed scientific knowledge to develop in many areas. As these sciences received wider attention from the elite, more scholars were invited and funded to study particular sciences, an example of a translator and mathematician who benefited from this type of support was al-Khawarizmi. A notable feature of many working under Muslim rule in medieval times is that they were often polymaths. Examples include the work on optics, maths and astronomy of Ibn al-Haytham, the Renaissance brought an increased emphasis on mathematics and science to Europe. As time passed, many gravitated towards universities. Moving into the 19th century, the objective of universities all across Europe evolved from teaching the “regurgitation of knowledge” to “encourag productive thinking. ”Thus, seminars, overall, science became the focus of universities in the 19th and 20th centuries. Students could conduct research in seminars or laboratories and began to produce doctoral theses with more scientific content. According to Humboldt, the mission of the University of Berlin was to pursue scientific knowledge. ”Mathematicians usually cover a breadth of topics within mathematics in their undergraduate education, and then proceed to specialize in topics of their own choice at the graduate level. In some universities, a qualifying exam serves to test both the breadth and depth of an understanding of mathematics, the students, who pass, are permitted to work on a doctoral dissertation. Mathematicians involved with solving problems with applications in life are called applied mathematicians. Applied mathematicians are mathematical scientists who, with their knowledge and professional methodology. With professional focus on a variety of problems, theoretical systems

Physical cosmology
–
Physical cosmology is the study of the largest-scale structures and dynamics of the Universe and is concerned with fundamental questions about its origin, structure, evolution, and ultimate fate. These advances made it possible to speculate about the origin of the universe, a few researchers still advocate a handful of alternative cosmologies, however, most cosmologists agree that the Big Bang theory explains the observations better. Cosmology draws heavily on the work of many areas of research in theoretical. Areas relevant to include particle physics experiments and theory, theoretical and observational astrophysics, general relativity, quantum mechanics. Modern cosmology developed along tandem tracks of theory and observation, in 1916, Albert Einstein published his theory of general relativity, which provided a unified description of gravity as a geometric property of space and time. At the time, Einstein believed in a universe. This is because masses distributed throughout the universe gravitationally attract, however, he realized that his equations permitted the introduction of a constant term which could counteract the attractive force of gravity on the cosmic scale. Einstein published his first paper on relativistic cosmology in 1917, in which he added this cosmological constant to his equations in order to force them to model a static universe. However, this so-called Einstein model is unstable to small perturbations—it will eventually start to expand or contract, the Einstein model describes a static universe, space is finite and unbounded. It was later realized that Einsteins model was just one of a set of possibilities, all of which were consistent with general relativity. The cosmological solutions of general relativity were found by Alexander Friedmann in the early 1920s and his equations describe the Friedmann–Lemaître–Robertson–Walker universe, which may expand or contract, and whose geometry may be open, flat, or closed. In the 1910s, Vesto Slipher interpreted the red shift of spiral nebulae as a Doppler shift that indicated they were receding from Earth, however, it is difficult to determine the distance to astronomical objects. One way is to compare the size of an object to its angular size. Another method is to measure the brightness of an object and assume an intrinsic luminosity, due to the difficulty of using these methods, they did not realize that the nebulae were actually galaxies outside our own Milky Way, nor did they speculate about the cosmological implications. In 1929, Edwin Hubble provided a basis for Lemaîtres theory. Hubble showed that the nebulae were galaxies by determining their distances using measurements of the brightness of Cepheid variable stars. He discovered a relationship between the redshift of a galaxy and its distance and he interpreted this as evidence that the galaxies are receding from Earth in every direction at speeds proportional to their distance. Given the cosmological principle, Hubbles law suggested that the universe was expanding, two primary explanations were proposed for the expansion

Quantum mechanics
–
Quantum mechanics, including quantum field theory, is a branch of physics which is the fundamental theory of nature at small scales and low energies of atoms and subatomic particles. Classical physics, the physics existing before quantum mechanics, derives from quantum mechanics as an approximation valid only at large scales, early quantum theory was profoundly reconceived in the mid-1920s. The reconceived theory is formulated in various specially developed mathematical formalisms, in one of them, a mathematical function, the wave function, provides information about the probability amplitude of position, momentum, and other physical properties of a particle. In 1803, Thomas Young, an English polymath, performed the famous experiment that he later described in a paper titled On the nature of light. This experiment played a role in the general acceptance of the wave theory of light. In 1838, Michael Faraday discovered cathode rays, Plancks hypothesis that energy is radiated and absorbed in discrete quanta precisely matched the observed patterns of black-body radiation. In 1896, Wilhelm Wien empirically determined a distribution law of black-body radiation, ludwig Boltzmann independently arrived at this result by considerations of Maxwells equations. However, it was only at high frequencies and underestimated the radiance at low frequencies. Later, Planck corrected this model using Boltzmanns statistical interpretation of thermodynamics and proposed what is now called Plancks law, following Max Plancks solution in 1900 to the black-body radiation problem, Albert Einstein offered a quantum-based theory to explain the photoelectric effect. Among the first to study quantum phenomena in nature were Arthur Compton, C. V. Raman, robert Andrews Millikan studied the photoelectric effect experimentally, and Albert Einstein developed a theory for it. In 1913, Peter Debye extended Niels Bohrs theory of structure, introducing elliptical orbits. This phase is known as old quantum theory, according to Planck, each energy element is proportional to its frequency, E = h ν, where h is Plancks constant. Planck cautiously insisted that this was simply an aspect of the processes of absorption and emission of radiation and had nothing to do with the reality of the radiation itself. In fact, he considered his quantum hypothesis a mathematical trick to get the right rather than a sizable discovery. He won the 1921 Nobel Prize in Physics for this work, lower energy/frequency means increased time and vice versa, photons of differing frequencies all deliver the same amount of action, but do so in varying time intervals. High frequency waves are damaging to human tissue because they deliver their action packets concentrated in time, the Copenhagen interpretation of Niels Bohr became widely accepted. In the mid-1920s, developments in mechanics led to its becoming the standard formulation for atomic physics. In the summer of 1925, Bohr and Heisenberg published results that closed the old quantum theory, out of deference to their particle-like behavior in certain processes and measurements, light quanta came to be called photons

General relativity
–
General relativity is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics. General relativity generalizes special relativity and Newtons law of gravitation, providing a unified description of gravity as a geometric property of space and time. In particular, the curvature of spacetime is directly related to the energy and momentum of whatever matter, the relation is specified by the Einstein field equations, a system of partial differential equations. Examples of such differences include gravitational time dilation, gravitational lensing, the redshift of light. The predictions of relativity have been confirmed in all observations. Although general relativity is not the only theory of gravity. Einsteins theory has important astrophysical implications, for example, it implies the existence of black holes—regions of space in which space and time are distorted in such a way that nothing, not even light, can escape—as an end-state for massive stars. The bending of light by gravity can lead to the phenomenon of gravitational lensing, General relativity also predicts the existence of gravitational waves, which have since been observed directly by physics collaboration LIGO. In addition, general relativity is the basis of current cosmological models of an expanding universe. Soon after publishing the special theory of relativity in 1905, Einstein started thinking about how to incorporate gravity into his new relativistic framework. In 1907, beginning with a thought experiment involving an observer in free fall. After numerous detours and false starts, his work culminated in the presentation to the Prussian Academy of Science in November 1915 of what are now known as the Einstein field equations. These equations specify how the geometry of space and time is influenced by whatever matter and radiation are present, the Einstein field equations are nonlinear and very difficult to solve. Einstein used approximation methods in working out initial predictions of the theory, but as early as 1916, the astrophysicist Karl Schwarzschild found the first non-trivial exact solution to the Einstein field equations, the Schwarzschild metric. This solution laid the groundwork for the description of the stages of gravitational collapse. In 1917, Einstein applied his theory to the universe as a whole, in line with contemporary thinking, he assumed a static universe, adding a new parameter to his original field equations—the cosmological constant—to match that observational presumption. By 1929, however, the work of Hubble and others had shown that our universe is expanding and this is readily described by the expanding cosmological solutions found by Friedmann in 1922, which do not require a cosmological constant. Lemaître used these solutions to formulate the earliest version of the Big Bang models, in which our universe has evolved from an extremely hot, Einstein later declared the cosmological constant the biggest blunder of his life

Differential geometry
–
Differential geometry is a mathematical discipline that uses the techniques of differential calculus, integral calculus, linear algebra and multilinear algebra to study problems in geometry. The theory of plane and space curves and surfaces in the three-dimensional Euclidean space formed the basis for development of differential geometry during the 18th century, since the late 19th century, differential geometry has grown into a field concerned more generally with the geometric structures on differentiable manifolds. Differential geometry is related to differential topology and the geometric aspects of the theory of differential equations. The differential geometry of surfaces captures many of the key ideas, Differential geometry arose and developed as a result of and in connection to the mathematical analysis of curves and surfaces. These unanswered questions indicated greater, hidden relationships, initially applied to the Euclidean space, further explorations led to non-Euclidean space, and metric and topological spaces. Riemannian geometry studies Riemannian manifolds, smooth manifolds with a Riemannian metric and this is a concept of distance expressed by means of a smooth positive definite symmetric bilinear form defined on the tangent space at each point. Various concepts based on length, such as the arc length of curves, area of plane regions, the notion of a directional derivative of a function from multivariable calculus is extended in Riemannian geometry to the notion of a covariant derivative of a tensor. Many concepts and techniques of analysis and differential equations have been generalized to the setting of Riemannian manifolds, a distance-preserving diffeomorphism between Riemannian manifolds is called an isometry. This notion can also be defined locally, i. e. for small neighborhoods of points, any two regular curves are locally isometric. In higher dimensions, the Riemann curvature tensor is an important pointwise invariant associated with a Riemannian manifold that measures how close it is to being flat, an important class of Riemannian manifolds is the Riemannian symmetric spaces, whose curvature is not necessarily constant. These are the closest analogues to the plane and space considered in Euclidean and non-Euclidean geometry. Pseudo-Riemannian geometry generalizes Riemannian geometry to the case in which the metric tensor need not be positive-definite, a special case of this is a Lorentzian manifold, which is the mathematical basis of Einsteins general relativity theory of gravity. Finsler geometry has the Finsler manifold as the object of study. This is a manifold with a Finsler metric, i. e. a Banach norm defined on each tangent space. Riemannian manifolds are special cases of the more general Finsler manifolds. A Finsler structure on a manifold M is a function F, TM → [0, ∞) such that, F = |m|F for all x, y in TM, F is infinitely differentiable in TM −, symplectic geometry is the study of symplectic manifolds. A symplectic manifold is an almost symplectic manifold for which the symplectic form ω is closed, a diffeomorphism between two symplectic manifolds which preserves the symplectic form is called a symplectomorphism. Non-degenerate skew-symmetric bilinear forms can only exist on even-dimensional vector spaces, in dimension 2, a symplectic manifold is just a surface endowed with an area form and a symplectomorphism is an area-preserving diffeomorphism

Cosmology
–
Cosmology is the study of the origin, evolution, and eventual fate of the universe. The term cosmology was first used in English in 1656 in Thomas Blounts Glossographia, religious or mythological cosmology is a body of beliefs based on mythological, religious, and esoteric literature and traditions of creation and eschatology. Physical cosmology is studied by scientists, such as astronomers and physicists, as well as philosophers, such as metaphysicians, philosophers of physics, and philosophers of space and time. Because of this scope with philosophy, theories in physical cosmology may include both scientific and non-scientific propositions, and may depend upon assumptions that can not be tested. Cosmology differs from astronomy in that the former is concerned with the Universe as a whole while the latter deals with individual celestial objects. Theoretical astrophysicist David N. Spergel has described cosmology as a science because when we look out in space. Physics and astrophysics have played a role in shaping the understanding of the universe through scientific observation. Physical cosmology was shaped through both mathematics and observation in an analysis of the whole universe, cosmogony studies the origin of the Universe, and cosmography maps the features of the Universe. In Diderots Encyclopédie, cosmology is broken down into uranology, aerology, geology, metaphysical cosmology has also been described as the placing of man in the universe in relationship to all other entities. Physical cosmology is the branch of physics and astrophysics that deals with the study of the physical origins and it also includes the study of the nature of the Universe on a large scale. In its earliest form, it was what is now known as celestial mechanics, greek philosophers Aristarchus of Samos, Aristotle, and Ptolemy proposed different cosmological theories. The geocentric Ptolemaic system was the theory until the 16th century when Nicolaus Copernicus. This is one of the most famous examples of epistemological rupture in physical cosmology, when Isaac Newton published the Principia Mathematica in 1687, he finally figured out how the heavens moved. A fundamental difference between Newtons cosmology and those preceding it was the Copernican principle—that the bodies on earth obey the same laws as all the celestial bodies. This was a crucial advance in physical cosmology. Physicists began changing the assumption that the Universe was static and unchanging, in 1922 Alexander Friedmann introduced the idea of an expanding universe that contained moving matter. In parallel to this approach to cosmology, one long-standing debate about the structure of the cosmos was coming to a climax. This difference of ideas came to a climax with the organization of the Great Debate on 26 April 1920 at the meeting of the U. S. National Academy of Sciences in Washington, D. C

Redshift
–
In physics, redshift happens when light or other electromagnetic radiation from an object is increased in wavelength, or shifted to the red end of the spectrum. Some redshifts are an example of the Doppler effect, familiar in the change of apparent pitches of sirens, a redshift occurs whenever a light source moves away from an observer. Finally, gravitational redshift is an effect observed in electromagnetic radiation moving out of gravitational fields. However, redshift is a common term and sometimes blueshift is referred to as negative redshift. Knowledge of redshifts and blueshifts has been applied to develop several terrestrial technologies such as Doppler radar and radar guns, Redshifts are also seen in the spectroscopic observations of astronomical objects. Its value is represented by the letter z, a special relativistic redshift formula can be used to calculate the redshift of a nearby object when spacetime is flat. However, in contexts, such as black holes and Big Bang cosmology. Special relativistic, gravitational, and cosmological redshifts can be understood under the umbrella of frame transformation laws, the history of the subject began with the development in the 19th century of wave mechanics and the exploration of phenomena associated with the Doppler effect. The effect is named after Christian Doppler, who offered the first known physical explanation for the phenomenon in 1842, the hypothesis was tested and confirmed for sound waves by the Dutch scientist Christophorus Buys Ballot in 1845. Doppler correctly predicted that the phenomenon should apply to all waves, before this was verified, however, it was found that stellar colors were primarily due to a stars temperature, not motion. Only later was Doppler vindicated by verified redshift observations, the first Doppler redshift was described by French physicist Hippolyte Fizeau in 1848, who pointed to the shift in spectral lines seen in stars as being due to the Doppler effect. The effect is called the Doppler–Fizeau effect. In 1868, British astronomer William Huggins was the first to determine the velocity of a moving away from the Earth by this method. In 1871, optical redshift was confirmed when the phenomenon was observed in Fraunhofer lines using solar rotation, about 0.1 Å in the red. In 1887, Vogel and Scheiner discovered the annual Doppler effect, in 1901, Aristarkh Belopolsky verified optical redshift in the laboratory using a system of rotating mirrors. The word does not appear unhyphenated until about 1934 by Willem de Sitter, perhaps indicating that up to point its German equivalent. Beginning with observations in 1912, Vesto Slipher discovered that most spiral galaxies, Slipher first reports on his measurement in the inaugural volume of the Lowell Observatory Bulletin. Three years later, he wrote a review in the journal Popular Astronomy, Slipher reported the velocities for 15 spiral nebulae spread across the entire celestial sphere, all but three having observable positive velocities

Solar radiation
–
Solar irradiance is the power per unit area received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Irradiance may be measured in space or at the Earths surface after atmospheric absorption and it is measured perpendicular to the incoming sunlight. Total solar irradiance, is a measure of the power over all wavelengths per unit area incident on the Earths upper atmosphere. The solar constant is a measure of mean TSI at a distance of one astronomical Unit. Irradiance is a function of distance from the Sun, the solar cycle, Irradiance on Earth is also measured perpendicular to the incoming sunlight. Insolation is the received on Earth per unit area on a horizontal surface. It depends on the height of the Sun above the horizon, the solar irradiance integrated over time is called solar irradiation, solar exposure or insolation. However, insolation is often used interchangeably with irradiance in practice, the SI unit of irradiance is watt per square meter. An alternate unit of measure is the Langley per unit time, the solar energy industry uses watt-hour per square metre per unit time, the relation to the SI unit is thus 1 kW/m2 =24 kWh/m2/day =8760 kWh/m2/year. Irradiance can also be expressed in Suns, where one Sun equals 1000 W/m2 at the point of arrival, part of the radiation reaching an object is absorbed and the remainder reflected. Usually the absorbed radiation is converted to energy, increasing the objects temperature. Manmade or natural systems, however, can convert part of the radiation into another form such as electricity or chemical bonds. The proportion of reflected radiation is the objects reflectivity or albedo, insolation onto a surface is largest when the surface directly faces the sun. As the angle between the surface and the Sun moves from normal, the insolation is reduced in proportion to the angles cosine, see effect of sun angle on climate. In the figure, the angle shown is between the ground and the rather than between the vertical direction and the sunbeam, hence the sine rather than the cosine is appropriate. A sunbeam one mile wide arrives from directly overhead, and another at a 30° angle to the horizontal, the sine of a 30° angle is 1/2, whereas the sine of a 90° angle is 1. Therefore, the angled sunbeam spreads the light over twice the area, consequently, half as much light falls on each square mile. This projection effect is the reason why Earths polar regions are much colder than equatorial regions

Angular momentum
–
In physics, angular momentum is the rotational analog of linear momentum. It is an important quantity in physics because it is a conserved quantity – the angular momentum of a system remains constant unless acted on by an external torque. The definition of momentum for a point particle is a pseudovector r×p. This definition can be applied to each point in continua like solids or fluids, unlike momentum, angular momentum does depend on where the origin is chosen, since the particles position is measured from it. The angular momentum of an object can also be connected to the angular velocity ω of the object via the moment of inertia I. However, while ω always points in the direction of the rotation axis, Angular momentum is additive, the total angular momentum of a system is the vector sum of the angular momenta. For continua or fields one uses integration, torque can be defined as the rate of change of angular momentum, analogous to force. Applications include the gyrocompass, control moment gyroscope, inertial systems, reaction wheels, flying discs or Frisbees. In general, conservation does limit the motion of a system. In quantum mechanics, angular momentum is an operator with quantized eigenvalues, Angular momentum is subject to the Heisenberg uncertainty principle, meaning only one component can be measured with definite precision, the other two cannot. Also, the spin of elementary particles does not correspond to literal spinning motion, Angular momentum is a vector quantity that represents the product of a bodys rotational inertia and rotational velocity about a particular axis. Angular momentum can be considered an analog of linear momentum. Thus, where momentum is proportional to mass m and linear speed v, p = m v, angular momentum is proportional to moment of inertia I. Unlike mass, which only on amount of matter, moment of inertia is also dependent on the position of the axis of rotation. Unlike linear speed, which occurs in a line, angular speed occurs about a center of rotation. Therefore, strictly speaking, L should be referred to as the angular momentum relative to that center and this simple analysis can also apply to non-circular motion if only the component of the motion which is perpendicular to the radius vector is considered. In that case, L = r m v ⊥, where v ⊥ = v sin θ is the component of the motion. It is this definition, × to which the moment of momentum refers

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

National Defense Research Committee
–
Most of its work was done with the strictest secrecy, and it began research of what would become some of the most important technology during World War II, including radar and the atomic bomb. It was superseded by the Office of Scientific Research and Development in 1941, Bush managed to get a meeting with the President on June 12,1940, and took a single sheet of paper describing the proposed agency. Roosevelt approved it in ten minutes and that, in fact, is exactly what it was. One member was appointed by the Secretary of War and another by the Secretary of the Navy, Conant, President of Harvard University, Frank B. Jewett, President of the National Academy of Sciences and President of Bell Telephone Laboratories, Brigadier General George V. Strong, Tolman, Professor of Physical Chemistry and Mathematical Physics at California Institute of Technology. Strong was succeeded by Brigadier General R. C. Moore on January 17,1941, during its first meeting on July 2, the NDRC elected Tolman as its Vice-Chairman and appointed Irvin Stewart as its Secretary. The NDRC members met approximately once a month until September 1942, after which it met weekly or bi-weekly until the end of the war with Germany. The former grew to be the largest single activity of the NDRC, in the year of its autonomous existence, the NDRC received approximately $6,500,000 for research. The NDRCs most important project eventually became the Manhattan Project — the full-scale project to nuclear weapons by the United States. It was instructed in Roosevelts June 15 letter to report to the NDRC and Bush, during June 1940 Bush reorganized the Uranium Committee into a scientific body and eliminated military membership. No longer beholden to the military for funds, the NDRC had greater access to money for nuclear research, however, there was little impetus until the British MAUD Committees findings were presented in 1941. At Bushs insistence Roosevelt issued Executive Order No.8807 on June 28,1941, the NDRC technically still existed after the creation of the OSRD but its authority had been reduced from being able to actually fund research to becoming simply an advisory body to the OSRD. The NDRC ceased to exist officially after its last meeting on January 20,1947, when it became the NDRC of the OSRD, the committee membership and structure was re-organized. The NDRC of the OSRD membership consisted of Conant, Tolman, Adams, Compton, and Jewett, along with the Commission of Patents, the Committee on Uranium was reorganized as the S-1 Section and it stopped being part of NDRC jurisdiction during December 1941. The NDRC funded research into hundreds of different projects at different educational and industrial sites around the country. During early June 1941, shortly before it was superseded by the OSRD, its organization was as follows, Section B Section H Section S Section T Section E Division B – James B. Conant, Chairman Synthetic Problems — Roger Adams, Vice-Chairman Section A-1 Section A-2 Section A-3 Section A-4 Physical Chemical Problems – W. K, jolliffe, Hartley Rowe, R. D. Booth, and J. T.

United States Secretary of War
–
The Secretary of War was a member of the United States Presidents Cabinet, beginning with George Washingtons administration. A similar position, called either Secretary at War or Secretary of War, had appointed to serve the Congress of the Confederation under the Articles of Confederation between 1781 and 1789. Benjamin Lincoln and later Henry Knox held the position, when Washington was inaugurated as the first president under the Constitution, he appointed Knox to continue serving. The Secretary of War was the head of the War Department, at first, he was responsible for all military affairs, including naval affairs. In 1798, the Secretary of the Navy was created by statute, from 1886 onward, the Secretary of War was third in the line of succession to the presidency, after the Vice President of the United States and the Secretary of State. The office of Secretary at War was modelled upon Great Britains Secretary at War, the office of Secretary at War was meant replaced both the Commander-in-Chief and the Board of War, and like the President of the Board, the Secretary wore no special insignia. The Inspector General, Quartermaster General, Commissary General, and Adjutant General served on the Secretarys staff, however, the Army itself under Secretary Henry Knox only consisted of 700 men.

Supreme Headquarters Allied Expeditionary Force
–
Supreme Headquarters Allied Expeditionary Force was the headquarters of the Commander of Allied forces in north west Europe, from late 1943 until the end of World War II. General Dwight D. Eisenhower was in command of SHAEF throughout its existence, the position itself shares a common lineage with Supreme Allied Commander Europe and Atlantic, but they are different titles. Southwick House was used as a headquarters near Portsmouth. Its staff took the plan for Operation Overlord created by Lieutenant General Sir Frederick E. Morgan, COSSAC. Morgan, who had appointed chief of staff to the Supreme Allied Commander in mid-March 1943 began planning for the invasion of Europe before Eisenhowers appointment. And moulded it into the version, which was executed on 6 June 1944. That process was shaped by Eisenhower and the forces commander for the initial part of the invasion. SHAEF remained in the United Kingdom until sufficient forces were ashore to justify its transfer to France, at that point, Montgomery ceased to command all land forces but continued as Commander in Chief of the British 21st Army Group on the eastern wing of the Normandy bridgehead. The American 12th Army Group commanded by Lieutenant General Omar Bradley was created as the wing of the bridgehead. During the invasion of southern France, the 6 AG was under the command of the Allied Forces Headquarters of the Mediterranean Theatre of Operations, by December 1944, SHAEF had established itself in the Trianon Palace Hotel in Versailles, France. In February 1945, it moved to Rheims and on 26 April 1945, SHAEF commanded the largest number of formations ever committed to one operation on the Western Front, with American, French army of liberation, British and Canadian Army forces. Allied strategic bomber forces in the UK also came under its command during Operation Neptune, Bradley Lieutenant General Jacob L. Devers Air Forces Commander, Air Marshal Sir Trafford Leigh-Mallory Naval Forces Commander, Admiral Sir Bertram Ramsay. After the surrender of Germany, SHAEF was dissolved on 14 July 1945 and, with respect to the US forces, was replaced by US Forces, USFET was reorganized as EUCOM on 15 March 1947.

Office of the Secretary of Defense
–
The Office of the Secretary of Defense is a headquarters-level staff of the Department of Defense of the United States of America. All of these positions are Presidential appointments which require U. S. Senate confirmation, the Secretary and Deputy Secretary manage several Under Secretaries each of whom in turn manage several Assistant Secretaries of Defense. There are also several special officers reporting directly to Secretary of Defense, during the Obama administration, Congress has sought to clarify the organization of OSD, and has worked with the Department to move toward a standardization of official naming conventions. S. Levin was concerned that the proliferation of DUSDs at multiple levels of the organization could muddy lines of authority, subsequent legislation established five Senate-confirmed Principal Deputies, one for each Under Secretary of Defense. The FY10 NDAA gave the Department of Defense until January 1,2011, the FY11 NDAA extended this deadline to January 1,2015. During that time, the Secretary may, at his or her discretion, the USD appears to be maintaining at least three non-PAS DUSDs, although they have been renamed. The USD has maintained the non-PAS DUSD for Installations and Environment, though the FY11 NDAA recommended merging this post with the newly created ASD for Operational Energy Plans and Programs. The USD has maintained a non-PAS DUSD for Strategy, Plans, and Forces, though the FY11 NDAA recommended eliminating this position

Robertson Panel
–
The Robertson Panel was a scientific committee which met in January 1953 headed by Howard P. Robertson. The CIA review itself was in response to reports of unidentified flying objects, especially in the Washington. The panel was briefed on U. S. military activities, most UFO reports, they concluded, could be explained as misidentification of mundane aerial objects, and the remaining minority could, in all likelihood, be similarly explained with further study. This wider document is referred to as the Durant Report. In 1952 there was a significant increase in the number of UFO reports received by the USAF Blue Book project and this wave included widely reported incidents over Washington DC in July, over the weekends of July 19-20 and 26-27. CIA historian Gerald Haines noted “A massive build-up of sightings over the United States in 1952, especially in July, on 19 and 20 July, radar scopes at Washington National Airport and Andrews Air Force Base tracked mysterious blips. On 27 July, the blips reappeared, the Air Force scrambled interceptor aircraft to investigate, but they found nothing. The incidents, however, caused headlines across the country, the White House wanted to know what was happening…”. Although this office has maintained a continuing review of such reported sightings during the past three years, a study group has been formed to review this subject to date. D/CI will participate in the study with D/SI and a report should be ready about 15 August. ”This is the earliest written record of the CIA study which led to the Robertson Panel, the precise origins of the decision to establish the review are unclear. A claim that the study was initiated by a Presidential request to the National Security Council appears to be incorrect. No NSC meetings were held on the relevant dates and the President was in Kansas on the 27 and 28 July, resting after attending the Democratic Party convention on the 26th. The Ralph L Clark memo of the 29th July contains a reference to a meeting, “OSI, FCD. The decision appears to have been a decision taken outside of formal structures such as NSC meetings. However, it is important that there are many who believe in them and this whole affair has demonstrated that there is a fair proportion of our population which is mentally conditioned to acceptance of the incredible. Thus we arrive at two points which, in a situation of international tension, seem to have National Security implications. Air Force is aware of this and had investigated a number of the groups that have sprung up to follow the subject. One - the Civilian Saucer Committee in California has substantial funds, Air Force is watching this organization because of its power to touch off mass hysteria and panic

Unidentified flying object
–
An unidentified flying object, or UFO, in its most general definition, is any apparent anomaly in the sky that is not identifiable as a known object or phenomenon. Culturally, UFOs are associated with claims of visitation by extraterrestrial life or government-related conspiracy theories, UFOs are often identified after their sighting. Sometimes, however, UFOs cannot be identified because of the low quality of evidence related to their sightings, during the late 1940s and through the 1950s, UFOs were often referred to popularly as flying saucers or flying discs. The term UFO became more widespread during the 1950s, at first in technical literature, UFOs garnered considerable interest during the Cold War, an era associated with a heightened concern for national security. Various studies have concluded that the phenomenon does not represent a threat to national security nor does it contain anything worthy of scientific pursuit, the Oxford English Dictionary defines a UFO as An unidentified flying object, a flying saucer. The first published book to use the word was authored by Donald E. Keyhoe, the acronym UFO was coined by Captain Edward J. Ruppelt, who headed Project Blue Book, then the USAFs official investigation of UFOs. He wrote, Obviously the term flying saucer is misleading when applied to objects of every conceivable shape, for this reason the military prefers the more general, if less colorful, name, unidentified flying objects. Other phrases that were used officially and that predate the UFO acronym include flying flapjack, flying disc, unexplained flying discs, unidentifiable object, the phrase flying saucer had gained widespread attention after the summer of 1947. On June 24, a pilot named Kenneth Arnold reported seeing nine objects flying in formation near Mount Rainier. Arnold timed the sighting and estimated the speed of discs to be over 1,200 mph, at the time, he claimed he described the objects flying in a saucer-like fashion, leading to newspaper accounts of flying saucers and flying discs. In popular usage, the term UFO came to be used to refer to claims of alien spacecraft, between 5% and 20% of reported sightings are not explained, and therefore can be classified as unidentified in the strictest sense. The term Ufology is used to describe the efforts of those who study reports. UFOs have become a prevalent theme in culture, and the social phenomena have been the subject of academic research in sociology and psychology. Unexplained aerial observations have been reported throughout history, an example is Halleys Comet, which was recorded first by Chinese astronomers in 240 BC and possibly as early as 467 BC. Such sightings throughout history often were treated as supernatural portents, angels, or other religious omens. On January 25,1878, the Denison Daily News printed an article in which John Martin, Martin, according to the newspaper account, said it appeared to be about the size of a saucer, the first known use of the word saucer in association with a UFO. In April 1897, thousands of people reported seeing airships in various parts of the United States, scores of people even reported talking to the pilots. Thomas Edison was asked his opinion, and said, You can take it from me that it is a pure fake, the largest had an apparent size of about six Suns, he said

NATO
–
The North Atlantic Treaty Organization, also called the North Atlantic Alliance, is an intergovernmental military alliance based on the North Atlantic Treaty which was signed on 4 April 1949. The organization constitutes a system of collective defence whereby its member states agree to mutual defence in response to an attack by any external party, three NATO members are permanent members of the United Nations Security Council with the power to veto and are officially nuclear-weapon states. NATOs headquarters are located in Haren, Brussels, Belgium, while the headquarters of Allied Command Operations is near Mons. NATO is an Alliance that consists of 28 independent member countries across North America and Europe, an additional 22 countries participate in NATOs Partnership for Peace program, with 15 other countries involved in institutionalized dialogue programmes. The combined military spending of all NATO members constitutes over 70% of the global total, Members defence spending is supposed to amount to 2% of GDP. The course of the Cold War led to a rivalry with nations of the Warsaw Pact, politically, the organization sought better relations with former Warsaw Pact countries, several of which joined the alliance in 1999 and 2004. N. The Treaty of Brussels, signed on 17 March 1948 by Belgium, the Netherlands, Luxembourg, France, the treaty and the Soviet Berlin Blockade led to the creation of the Western European Unions Defence Organization in September 1948. However, participation of the United States was thought necessary both to counter the power of the USSR and to prevent the revival of nationalist militarism. He got a hearing, especially considering American anxiety over Italy. In 1948 European leaders met with U. S. defense, military and diplomatic officials at the Pentagon, marshalls orders, exploring a framework for a new and unprecedented association. Talks for a new military alliance resulted in the North Atlantic Treaty and it included the five Treaty of Brussels states plus the United States, Canada, Portugal, Italy, Norway, Denmark and Iceland. The first NATO Secretary General, Lord Ismay, stated in 1949 that the goal was to keep the Russians out, the Americans in. Popular support for the Treaty was not unanimous, and some Icelanders participated in a pro-neutrality, the creation of NATO can be seen as the primary institutional consequence of a school of thought called Atlanticism which stressed the importance of trans-Atlantic cooperation. The members agreed that an attack against any one of them in Europe or North America would be considered an attack against them all. The treaty does not require members to respond with military action against an aggressor, although obliged to respond, they maintain the freedom to choose the method by which they do so. This differs from Article IV of the Treaty of Brussels, which states that the response will be military in nature. It is nonetheless assumed that NATO members will aid the attacked member militarily, the treaty was later clarified to include both the members territory and their vessels, forces or aircraft above the Tropic of Cancer, including some Overseas departments of France. The creation of NATO brought about some standardization of allied military terminology, procedures, and technology, the roughly 1300 Standardization Agreements codified many of the common practices that NATO has achieved

Supreme Headquarters Allied Powers Europe
–
Supreme Headquarters Allied Powers Europe is the headquarters of the North Atlantic Treaty Organizations Allied Command Operations. Since 1967 it has been located at Casteau, north of the Belgian city of Mons, from 1951 to 2003, SHAPE was the headquarters of Allied Command Europe, ACE. Since 2003 it has been the headquarters of Allied Command Operations, SHAPE retained its traditional name with reference to Europe for legal reasons although the geographical scope of its activities was extended in 2003. At that time, NATOs command in Lisbon, historically part of the Atlantic command, was reassigned to ACO, an integrated military structure for NATO was first established after the Korean War raised questions over the strength of Europes defences against a Soviet attack. The first choice for commander in Europe was American General of the Army Dwight D, on December 19,1950, the North Atlantic Council announced the appointment of General Eisenhower as the first SACEUR. British Field Marshal Sir Bernard L, montgomery moved over from the predecessor Western Union Defence Organization to become the first Deputy SACEUR, who would serve until 1958. In establishing the command, the first NATO planners drew extensively on WUDO plans, General Eisenhower arrived in Paris on January 1,1951, and quickly set to work with a small group of planners to devise a structure for the new European command. The Planning Group worked in the Hotel Astoria in central Paris while construction of a permanent facility began at Rocquencourt, just west of the city, devising command arrangements in the Central Region, which contained the bulk of NATO’s forces, proved to be much more complicated. Drawing upon his World War II experience, General Eisenhower decided to retain overall control himself, instead there would be three separate C-in-Cs. In December 1950 it was announced that the forces initially to come under General Eisenhowers command were to be the U. S, on April 2,1951, General Eisenhower signed the activation order for Allied Command Europe and its headquarters at SHAPE. Headquarters, Allied Forces Central Europe was activated in Fontainebleau, France in 1953, on the same day, ACEs subordinate headquarters in Northern and Central Europe were activated, with the Southern Region following in June. By 1954 ACEs forces consisted of Allied Forces Northern Europe, at Oslo, Allied Forces Central Europe, Allied Forces Southern Europe, hodes, United States Army Allied Forces Southern Europe – Admiral R. P. M. Two 1952 central region exercises involved air-ground combined forces, equinox was a major air-ground exercise involving French-American tactical air units and a French airborne infantry unit under the command of Général dArmée Alphonse Juin, French Army. They maneuvered east of the Rhine River in the British Zone under the command of Lt. General Sir Richard Nelson Gale. Finally, Rosebud involved ground maneuvers by the U. S, seventh Army in the American Zone of Occupation of Allied-occupied Germany. The initial plans saw the defence of Western Europe from a Soviet invasion resting heavily on nuclear weapons, the conventional forces would attempt to hold this line while the allied strategic air forces defeated the Soviets and their allies by destroying their economy and infrastructure. What this strategy meant for the battle in the central region was described for publicity purposes in January 1954 by then-Supreme Allied Commander Europe General Alfred Gruenther as. An air-ground shield which, although still not strong enough, would force an enemy to concentrate prior to attack, in doing so, the concentrating force would be extremely vulnerable to losses from atomic weapon attacks

Seattle
–
Seattle is a seaport city on the west coast of the United States and the seat of King County, Washington. With an estimated 684,451 residents as of 2015, Seattle is the largest city in both the state of Washington and the Pacific Northwest region of North America. In July 2013, it was the major city in the United States. The city is situated on an isthmus between Puget Sound and Lake Washington, about 100 miles south of the Canada–United States border, a major gateway for trade with Asia, Seattle is the fourth-largest port in North America in terms of container handling as of 2015. The Seattle area was inhabited by Native Americans for at least 4,000 years before the first permanent European settlers. Arthur A. Denny and his group of travelers, subsequently known as the Denny Party, arrived from Illinois via Portland, the settlement was moved to the eastern shore of Elliott Bay and named Seattle in 1852, after Chief Siahl of the local Duwamish and Suquamish tribes. Logging was Seattles first major industry, but by the late-19th century, growth after World War II was partially due to the local Boeing company, which established Seattle as a center for aircraft manufacturing. The Seattle area developed as a technology center beginning in the 1980s, in 1994, Internet retailer Amazon was founded in Seattle. The stream of new software, biotechnology, and Internet companies led to an economic revival, Seattle has a noteworthy musical history. From 1918 to 1951, nearly two dozen jazz nightclubs existed along Jackson Street, from the current Chinatown/International District, to the Central District, the jazz scene developed the early careers of Ray Charles, Quincy Jones, Ernestine Anderson, and others. Seattle is also the birthplace of rock musician Jimi Hendrix and the alternative rock subgenre grunge, archaeological excavations suggest that Native Americans have inhabited the Seattle area for at least 4,000 years. By the time the first European settlers arrived, the people occupied at least seventeen villages in the areas around Elliott Bay, the first European to visit the Seattle area was George Vancouver, in May 1792 during his 1791–95 expedition to chart the Pacific Northwest. In 1851, a party led by Luther Collins made a location on land at the mouth of the Duwamish River. Thirteen days later, members of the Collins Party on the way to their claim passed three scouts of the Denny Party, members of the Denny Party claimed land on Alki Point on September 28,1851. The rest of the Denny Party set sail from Portland, Oregon, after a difficult winter, most of the Denny Party relocated across Elliott Bay and claimed land a second time at the site of present-day Pioneer Square, naming this new settlement Duwamps. For the next few years, New York Alki and Duwamps competed for dominance, david Swinson Doc Maynard, one of the founders of Duwamps, was the primary advocate to name the settlement after Chief Sealth of the Duwamish and Suquamish tribes. The name Seattle appears on official Washington Territory papers dated May 23,1853, in 1855, nominal land settlements were established. On January 14,1865, the Legislature of Territorial Washington incorporated the Town of Seattle with a board of managing the city

Bachelor of Science
–
A Bachelor of Science is an undergraduate academic degree awarded for completed courses that generally last three to five years. Whether a student of a subject is awarded a Bachelor of Science degree or a Bachelor of Arts degree can vary between universities. For one example, a degree may be given as a Bachelor of Arts by one university but as a B. Sc. by another. Some liberal arts colleges in the United States offer only the BA, even in the natural sciences, in both instances, there are historical and traditional reasons. Northwestern Universitys School of Communication grants B. Sc. degrees in all of its programs of study, including theater, dance, the first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. Prior to this, science subjects were included in the B. A. bracket, notably in the cases of mathematics, physics, physiology, in Argentina and Chile, most university degrees are given as a license in a field or discipline. For instance, besides the courses, biochemistry and biology require 1–2 years hands-on training either in a clinical laboratory plus a final exam or in a research laboratory plus a thesis defense. The degrees are term licenses in the field of study or profession i. e. biology, nutrition, physical therapy or kinesiology, etc. However, a masters degree requires 2-3 more years of specific training, engineering and medical degrees are also different and are six-year programs of specific classes and training starting immediately after high school. No intermediate degrees count towards the admission examination or even exist, medical degrees are complemented with a 3–4 years of hospital residence plus 1–2 years of specialization training. In Australia, the B. Sc. is generally a three-four year degree, an honours year or a Master of Science is required to progress on to the Doctor of Philosophy. In New Zealand, in cases, the honours degree comprises an additional postgraduate qualification. In South Africa, the B. Sc. is taken three years, while the postgraduate B. Sc. Entails an additional year of study, admission to the honours degree is on the basis of a sufficiently high average in the B. Sc. major, an honours degree is required for M. Sc. Level study, and admission to a doctorate is via the M. Sc, commonly in British Commonwealth countries and Ireland graduands are admitted to the degree of Bachelor of Science after having completed a programme in one or more of the sciences. These programmes may take different lengths of time to complete, note that in British English, no full stops are used in the title, hence BSc, not B. Sc. A Bachelor of Science receives the designation BSc or BS for a major/pass degree, in England, Wales and Northern Ireland an honours degree is typically completed over a three-year period, though there are a few intensified two-year courses. Bachelors degrees were typically completed in two years for most of the twentieth century, in Scotland, where access to university is possible after one less year of secondary education, degree courses have a foundation year making the total course length four years

Peter Ward Fay was a noted historian and authority on India and China. He was a professor at the California Institute of Technology from 1955 until his retirement in 1997, professor Fay received his bachelors degree from Harvard in 1947, where his studies were interrupted to serve in Italy during World War II. Afterwards, he attended Oxford University as a Rhodes Scholar and then returned to Harvard for his Ph. D. which he received in 1954, after a brief period teaching at Williams College, he came to Caltech, where he remained for the rest of his career. At Caltech, Fay taught a variety of courses in European history and also developed an interest in Asia, especially India and China. Among his books were the award-winning The Opium War, 1840-1842 and The Forgotten Army, Indias Armed Struggle for Independence and his two years spent at the Indian Institute of Technology during the 1960s helped form his interest in Indian history

Doctor of Philosophy
–
A Doctor of Philosophy is a type of doctoral degree awarded by universities in many countries. Ph. D. s are awarded for a range of programs in the sciences, engineering. The Ph. D. is a degree in many fields. The completion of a Ph. D. is often a requirement for employment as a university professor, researcher, individuals with an earned doctorate can use the title of Doctor with their name and use the post-nominal letters Ph. D. The requirements to earn a Ph. D. degree vary considerably according to the country, institution, a person who attains a doctorate of philosophy is automatically awarded the academic title of doctor. A student attaining this level may be granted a Candidate of Philosophy degree at some institutions. A Ph. D. candidate must submit a project, thesis or dissertation often consisting of a body of academic research. In many countries, a candidate must defend this work before a panel of examiners appointed by the university. Universities award other types of doctorates besides the Ph. D. such as the Doctor of Musical Arts, a degree for music performers and the Doctor of Education, in 2016, ELIA launched The Florence Principles on the Doctorate in the Arts. The Florence Principles have been endorsed are supported also by AEC, CILECT, CUMULUS, the degree is abbreviated PhD, from the Latin Philosophiae Doctor, pronounced as three separate letters. In the universities of Medieval Europe, study was organized in four faculties, the faculty of arts. All of these faculties awarded intermediate degrees and final degrees, the doctorates in the higher faculties were quite different from the current Ph. D. degree in that they were awarded for advanced scholarship, not original research. No dissertation or original work was required, only lengthy residency requirements, besides these degrees, there was the licentiate. According to Keith Allan Noble, the first doctoral degree was awarded in medieval Paris around 1150, the doctorate of philosophy developed in Germany as the terminal Teachers credential in the 17th century. Typically, upon completion, the candidate undergoes an oral examination, always public, starting in 2016, in Ukraine Doctor of Philosophy is the highest education level and the first science degree. PhD is awarded in recognition of a contribution to scientific knowledge. A PhD degree is a prerequisite for heading a university department in Ukraine, upon completion of a PhD, a PhD holder can elect to continue his studies and get a post-doctoral degree called Doctor of Sciences, which is the second and the highest science degree in Ukraine. Scandinavian countries were among the early adopters of a known as a doctorate of philosophy

David Hilbert
–
David Hilbert was a German mathematician. He is recognized as one of the most influential and universal mathematicians of the 19th, Hilbert discovered and developed a broad range of fundamental ideas in many areas, including invariant theory and the axiomatization of geometry. He also formulated the theory of Hilbert spaces, one of the foundations of functional analysis, Hilbert adopted and warmly defended Georg Cantors set theory and transfinite numbers. A famous example of his leadership in mathematics is his 1900 presentation of a collection of problems set the course for much of the mathematical research of the 20th century. Hilbert and his students contributed significantly to establishing rigor and developed important tools used in mathematical physics. Hilbert is known as one of the founders of theory and mathematical logic. In late 1872, Hilbert entered the Friedrichskolleg Gymnasium, but, after a period, he transferred to. Upon graduation, in autumn 1880, Hilbert enrolled at the University of Königsberg, in early 1882, Hermann Minkowski, returned to Königsberg and entered the university. Hilbert knew his luck when he saw it, in spite of his fathers disapproval, he soon became friends with the shy, gifted Minkowski. In 1884, Adolf Hurwitz arrived from Göttingen as an Extraordinarius, Hilbert obtained his doctorate in 1885, with a dissertation, written under Ferdinand von Lindemann, titled Über invariante Eigenschaften spezieller binärer Formen, insbesondere der Kugelfunktionen. Hilbert remained at the University of Königsberg as a Privatdozent from 1886 to 1895, in 1895, as a result of intervention on his behalf by Felix Klein, he obtained the position of Professor of Mathematics at the University of Göttingen. During the Klein and Hilbert years, Göttingen became the preeminent institution in the mathematical world and he remained there for the rest of his life. Among Hilberts students were Hermann Weyl, chess champion Emanuel Lasker, Ernst Zermelo, john von Neumann was his assistant. At the University of Göttingen, Hilbert was surrounded by a circle of some of the most important mathematicians of the 20th century, such as Emmy Noether. Between 1902 and 1939 Hilbert was editor of the Mathematische Annalen, good, he did not have enough imagination to become a mathematician. Hilbert lived to see the Nazis purge many of the prominent faculty members at University of Göttingen in 1933 and those forced out included Hermann Weyl, Emmy Noether and Edmund Landau. One who had to leave Germany, Paul Bernays, had collaborated with Hilbert in mathematical logic and this was a sequel to the Hilbert-Ackermann book Principles of Mathematical Logic from 1928. Hermann Weyls successor was Helmut Hasse, about a year later, Hilbert attended a banquet and was seated next to the new Minister of Education, Bernhard Rust

Richard Courant
–
Richard Courant was a German American mathematician. He is best known by the public for the book What is Mathematics. Courant was born in Lublinitz, in the Prussian Province of Silesia and his parents were Siegmund Courant and Martha Courant née Freund of Oels. Edith Stein was Richards cousin on the paternal side, during his youth his parents moved often, including to Glatz, then to Breslau and in 1905 to Berlin. He stayed in Breslau and entered the university there, then continued his studies at the University of Zürich and he became David Hilberts assistant in Göttingen and obtained his doctorate there in 1910. He was obliged to serve in World War I, but was wounded shortly after enlisting and he continued his research in Göttingen and then engaged a two-year period at the University of Münster as professor of mathematics. There he founded the Mathematical Institute, which he headed as director from 1928 until 1933, Courant left Germany in 1933, earlier than many Jewish escapees. In 1936, after one year at Cambridge, Courant accepted a professorship at New York University in New York City, there he founded an institute for graduate studies in applied mathematics. The Courant Institute of Mathematical Sciences is now one of the most respected research centers in applied mathematics, Courant and David Hilbert authored the influential textbook Methoden der mathematischen Physik which, with its revised editions, is still current and widely used since its publication in 1924. With Herbert Robbins he coauthored a popular overview of mathematics, intended for the general public. Courants name is attached to the finite element method, with his numerical treatment of the plain torsion problem for multiply-connected domains. This method is now one of the ways to solve differential equations numerically. Courant is a namesake of the Courant–Friedrichs–Lewy condition and the Courant minimax principle, Courant died in New Rochelle, New York.

Albert Einstein
–
Albert Einstein was a German-born theoretical physicist. He developed the theory of relativity, one of the two pillars of modern physics, Einsteins work is also known for its influence on the philosophy of science. Einstein is best known in popular culture for his mass–energy equivalence formula E = mc2, near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led him to develop his theory of relativity during his time at the Swiss Patent Office in Bern. Briefly before, he aquired the Swiss citizenship in 1901, which he kept for his whole life and he continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the theory of relativity to model the large-scale structure of the universe. He was visiting the United States when Adolf Hitler came to power in 1933 and, being Jewish, did not go back to Germany and he settled in the United States, becoming an American citizen in 1940. This eventually led to what would become the Manhattan Project, Einstein supported defending the Allied forces, but generally denounced the idea of using the newly discovered nuclear fission as a weapon. Later, with the British philosopher Bertrand Russell, Einstein signed the Russell–Einstein Manifesto, Einstein was affiliated with the Institute for Advanced Study in Princeton, New Jersey, until his death in 1955. Einstein published more than 300 scientific papers along with over 150 non-scientific works, on 5 December 2014, universities and archives announced the release of Einsteins papers, comprising more than 30,000 unique documents. Einsteins intellectual achievements and originality have made the word Einstein synonymous with genius, Albert Einstein was born in Ulm, in the Kingdom of Württemberg in the German Empire, on 14 March 1879. His parents were Hermann Einstein, a salesman and engineer, the Einsteins were non-observant Ashkenazi Jews, and Albert attended a Catholic elementary school in Munich from the age of 5 for three years. At the age of 8, he was transferred to the Luitpold Gymnasium, the loss forced the sale of the Munich factory. In search of business, the Einstein family moved to Italy, first to Milan, when the family moved to Pavia, Einstein stayed in Munich to finish his studies at the Luitpold Gymnasium. His father intended for him to electrical engineering, but Einstein clashed with authorities and resented the schools regimen. He later wrote that the spirit of learning and creative thought was lost in strict rote learning, at the end of December 1894, he travelled to Italy to join his family in Pavia, convincing the school to let him go by using a doctors note. During his time in Italy he wrote an essay with the title On the Investigation of the State of the Ether in a Magnetic Field

Werner Heisenberg
–
Werner Karl Heisenberg was a German theoretical physicist and one of the key pioneers of quantum mechanics. He published his work in 1925 in a breakthrough paper, in the subsequent series of papers with Max Born and Pascual Jordan, during the same year, this matrix formulation of quantum mechanics was substantially elaborated. In 1927 he published his uncertainty principle, upon which he built his philosophy, Heisenberg was awarded the Nobel Prize in Physics for 1932 for the creation of quantum mechanics. He was a principal scientist in the Nazi German nuclear weapon project during World War II and he travelled to occupied Copenhagen where he met and discussed the German project with Niels Bohr. Following World War II, he was appointed director of the Kaiser Wilhelm Institute for Physics and he was director of the institute until it was moved to Munich in 1958, when it was expanded and renamed the Max Planck Institute for Physics and Astrophysics. He studied physics and mathematics from 1920 to 1923 at the Ludwig-Maximilians-Universität München, at Munich, he studied under Arnold Sommerfeld and Wilhelm Wien. At Göttingen, he studied physics with Max Born and James Franck and he received his doctorate in 1923, at Munich under Sommerfeld. He completed his Habilitation in 1924, at Göttingen under Born, at the event, Bohr was a guest lecturer and gave a series of comprehensive lectures on quantum atomic physics. There, Heisenberg met Bohr for the first time, and it had a significant, Heisenbergs doctoral thesis, the topic of which was suggested by Sommerfeld, was on turbulence, the thesis discussed both the stability of laminar flow and the nature of turbulent flow. The problem of stability was investigated by the use of the Orr–Sommerfeld equation and he briefly returned to this topic after World War II. Heisenbergs paper on the anomalous Zeeman effect was accepted as his Habilitationsschrift under Max Born at Göttingen, in his youth he was a member and Scoutleader of the Neupfadfinder, a German Scout association and part of the German Youth Movement. In August 1923 Robert Honsell and Heisenberg organized a trip to Finland with a Scout group of this association from Munich, Heisenberg arrived at Munich in 1919 as a member of Freikorps to fight the Bavarian Soviet Republic established a year earlier. Five decades later he recalled those days as youthful fun, like playing cops and robbers and so on, from 1924 to 1927, Heisenberg was a Privatdozent at Göttingen. His seminal paper, Über quantentheoretischer Umdeutung was published in September 1925 and he returned to Göttingen and with Max Born and Pascual Jordan, over a period of about six months, developed the matrix mechanics formulation of quantum mechanics. On 1 May 1926, Heisenberg began his appointment as a university lecturer and it was in Copenhagen, in 1927, that Heisenberg developed his uncertainty principle, while working on the mathematical foundations of quantum mechanics. On 23 February, Heisenberg wrote a letter to fellow physicist Wolfgang Pauli, in his paper on the uncertainty principle, Heisenberg used the word Ungenauigkeit. In 1927, Heisenberg was appointed ordentlicher Professor of theoretical physics and head of the department of physics at the Universität Leipzig, in his first paper published from Leipzig, Heisenberg used the Pauli exclusion principle to solve the mystery of ferromagnetism. Slater, Edward Teller, John Hasbrouck van Vleck, Victor Frederick Weisskopf, Carl Friedrich von Weizsäcker, Gregor Wentzel, in early 1929, Heisenberg and Pauli submitted the first of two papers laying the foundation for relativistic quantum field theory

Karl Schwarzschild
–
Karl Schwarzschild was a German physicist and astronomer. He was also the father of astrophysicist Martin Schwarzschild, Schwarzschild accomplished this while serving in the German army during World War I. He died the year from the autoimmune disease pemphigus, which he developed while at the Russian front. Various forms of the disease particularly affect people of Ashkenazi Jewish origin, asteroid 837 Schwarzschilda is named in his honour, as is the large crater Schwarzschild, on the far side of the moon. Schwarzschild was born in Frankfurt am Main to Jewish parents and his father was active in the business community of the city, and the family had ancestors in the city dating back to the sixteenth century. Karl attended a Jewish primary school until 11 years of age and he was something of a child prodigy, having two papers on binary orbits published before he was sixteen. He studied at Straßburg and Munich, obtaining his doctorate in 1896 for a work on Henri Poincarés theories, from 1897, he worked as assistant at the Kuffner observatory in Vienna. From 1901 until 1909 he was a professor at the institute at Göttingen. Schwarzschild became the director of the observatory in Göttingen and he married Else Posenbach, the daughter of a professor of surgery at Göttingen, in 1909, and later that year moved to Potsdam, where he took up the post of director of the Astrophysical Observatory. This was then the most prestigious post available for an astronomer in Germany and he and Else had three children, Agathe, Martin, and Alfred. From 1912, Schwarzschild was a member of the Prussian Academy of Sciences, at the outbreak of World War I in 1914 he joined the German army despite being over 40 years old. He served on both the western and eastern fronts, rising to the rank of lieutenant in the artillery, while serving on the front in Russia in 1915, he began to suffer from a rare and painful skin disease called pemphigus. Nevertheless, he managed to three outstanding papers, two on relativity theory and one on quantum theory. Schwarzschilds struggle with pemphigus may have led to his death. Thousands of dissertations, articles, and books have since been devoted to the study of Schwarzschilds solutions to the Einstein field equations, while at Vienna in 1897, Schwarzschild developed a formula, now known as the Schwarzschild law, to calculate the optical density of photographic material. It involved an exponent now known as the Schwarzschild exponent, which is the p in the formula and this formula was important for enabling more accurate photographic measurements of the intensities of faint astronomical sources. Two points on two world lines contribute to the Lagrangian only if they are a zero Minkowskian distance, hence the term δ, the idea was further developed by Tetrode and Fokker in the 1920s and Wheeler and Feynman in the 1940s and constitutes an alternative/equivalent formulation of electrodynamics. Einsteins approximate solution was given in his famous 1915 article on the advance of the perihelion of Mercury, there, Einstein used rectangular coordinates to approximate the gravitational field around a spherically symmetric, non-rotating, non-charged mass

Martin Schwarzschild
–
Martin Schwarzschild was a German-born American astrophysicist. He was the son of German physicist Karl Schwarzschild and the nephew of the Swiss astrophysicist Robert Emden, Schwarzschild was born in Potsdam into a distinguished German Jewish academic family. In line with a request in his fathers will, his family moved to Göttingen in 1916, Schwarzschild studied at the University of Göttingen and took his doctoral examination in December 1936. He left Germany in 1936 for Norway and then the United States, Schwarzschild served in the US army intelligence. He was awarded the Legion of Merit and the Bronze Star for his wartime service, after returning to the US, he married fellow astronomer Barbara Cherry. In 1947, Martin Schwarzschild joined his friend, Lyman Spitzer at Princeton University. Spitzer died 10 days before Schwarzschild, with Fred Hoyle, he computed some of the first stellar models to correctly ascend the red giant branch by steadily burning hydrogen in a shell around the core. Schwarzschild’s 1958 book Structure and Evolution of the Stars taught a generation of astrophysicists how to apply computers to the computation of stellar models. In the 1950s and ’60s he headed the Stratoscope projects, which took instrumented balloons to unprecedented heights, in his later years he made significant contributions toward understanding the dynamics of elliptical galaxies. Schwarzschild was renowned as a teacher and held leadership positions in several scientific societies. In the 1980s, Schwarzschild applied his skills to building models for triaxial galaxies. Dr. Schwarzschild was the Eugene Higgins Professor Emeritus of Astronomy at Princeton University, merritt, Martin Schwarzschilds Contributions to Galaxy Dynamics Oral history interview with Martin Schwarzschild. Charles Babbage Institute, University of Minnesota, Minneapolis, Schwarzschild answers questions about the relationship between R. H. His final topic is the work during the 1950s he undertook on stellar interiors using the Institute for Advanced Study computer and he describes his experiences trying to use the computer for large scientific purposes, and recalls the reception of his computational research by the professional astronomy journals
