Description Einstein Dissertation eth Date 30 April Source http: Inhe was awarded a PhD by the University of Zurich. The same year, he published four groundbreaking papers during his renowned annus mirabilis miracle year which brought him to the notice of the academic world at the age of Einstein taught theoretical physics at Zurich between and before he left for Berlin, where he was elected to the Prussian Academy of Sciences.
Because of his Jewish background, Einstein did not return to Germany. Roosevelt alerting him to the potential development of "extremely powerful bombs of a new type" and recommending that the US begin similar research. This eventually led to the Manhattan Project. Einstein supported the Alliesbut he generally denounced the idea of using nuclear fission as a weapon.
He signed the Russell—Einstein Manifesto with British philosopher Bertrand Russellwhich highlighted the danger of nuclear weapons. Einstein published more than scientific papers and more than non-scientific works. And that is a very remarkable statement. The Einsteins were non-observant Ashkenazi Jewsand 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 now known as the Albert Einstein Gymnasiumwhere he received advanced primary and secondary school education until he left the German Empire seven years later. In search of business, the Einstein family moved to Italy, first to Milan and a few months later to Pavia.
When the family moved to Pavia, Einstein, then 15, stayed in Munich to finish his studies at the Luitpold Gymnasium. He later wrote that the spirit of learning and creative thought was what a resume in strict rote learning.
Einstein always excelled at math and physics from a young age, reaching a mathematical level years ahead of his peers. The twelve year old Einstein taught himself algebra and Euclidean geometry over a single summer.
Einstein also independently discovered his own original proof of the Pythagorean theorem at age He thereupon devoted himself to higher mathematics Soon the flight of his mathematical genius was so high I could not follow. He failed to reach the required standard in the general part of the examination,  but obtained exceptional grades in physics and mathematics.
Marie Winteler, who was a year older, moved to OlsbergSwitzerland, for a teaching post. She was the only woman among the six students in the mathematics and physics section of the teaching diploma course. InEinstein passed the exams in Maths and Physics and was awarded the Federal Polytechnic teaching diploma. In letters revealed inEinstein wrote to his early love Marie Winteler about his marriage and his strong feelings for her.
He wrote inwhile his wife was pregnant with their second child: He spoke about a "misguided love" and a "missed life" regarding his love for Marie.
Elsa was diagnosed with heart and kidney problems in and died in December PosinMaurice Solovineand Hitler and stalin ideology Wise.
After graduating inEinstein spent almost two frustrating years searching for a teaching post. He acquired Swiss citizenship in February but for medical reasons was not conscripted. Einstein evaluated patent applications for a variety of devices including a gravel sorter and an electromechanical typewriter.
Much of his work at the patent office related to questions about transmission of electric signals and electrical—mechanical synchronization of time, two technical problems that show up conspicuously in the thought experiments that eventually led Einstein to his radical conclusions about the nature of light and the fundamental connection between space and time. With a few friends he had met in Bern, Einstein started a small discussion group inself-mockingly named " The Olympia Academy ", which met regularly to discuss science and philosophy.
Byhe was recognized as a leading scientist and was appointed lecturer at the University of Bern. Einstein was appointed associate professor in From untilhe was professor of theoretical physics at the ETH Zurichwhere he taught analytical mechanics and thermodynamics. He also studied continuum mechanicsthe molecular theory of heat, and the problem of gravitation, on which he worked with mathematician and friend Marcel Grossmann.
Max Planck an essay on the development of christian doctrine Walther Nernst visited him the next week in Zurich to persuade him to join the academy, additionally offering him the post of director at the Kaiser Wilhelm Institute for Physicswhich was soon to be established.
He was officially elected to the academy on 24 July, and he accepted to move to the German Empire the next do my homework for cash. His decision to move to Berlin was also influenced by the prospect of living near his cousin Elsa, with whom he had developed a romantic affair.
He joined the academy and thus the Berlin University on 1 April The institute was established on 1 Octoberwith Einstein as its director. Inthat prediction was confirmed by Sir Arthur Eddington during the solar eclipse of 29 May Those observations were published in the international media, making Einstein world-famous.
On 7 Novemberthe leading British newspaper The Times printed a banner headline that read: Einstein visited New York City for the first time on 2 Aprilwhere he received an official welcome by Mayor John Francis Hylanfollowed by three weeks of lectures and receptions. He went on to deliver several lectures at Columbia University and Princeton Universityand in Washington he accompanied representatives of the National Academy of Science on a visit to the White House.
He also published an essay, "My First Impression of the U. The American is friendly, self-confident, optimistic, and without envy.
Inhis travels took him to Asia and later to Palestine, as part of a six-month excursion and speaking tour, as he visited SingaporeCeylon and Japanwhere he gave a series of lectures to thousands of Japanese. After his first public lecture, he met the emperor and empress at the Imperial Palacewhere thousands came to watch.
In a letter to his sons, he described his impression of the Japanese as being modest, intelligent, considerate, and having a true feel for art. In his place, the banquet speech was held by a German diplomat, who praised Einstein not only as a scientist but also as an international peacemaker and activist.
On his return voyage, he visited Palestine for 12 days in what would become his only visit to that region. He was greeted as if he were a head of state, rather than a physicist, which included a cannon salute upon arriving at the home of the British high commissioner, Sir Herbert Samuel. During one reception, the building was stormed by people who wanted to see and hear him.
From toEinstein was a member of the International Committee on Intellectual Cooperation of the League of Nations in Geneva with a few months of interruption in — a body created to promote international exchange between scientists, researchers, teachers, artists and intellectuals.
In DecemberEinstein visited America for the second time, originally intended as a two-month working visit as a research fellow at the California Institute of Technology. After the national attention he received during his first trip to the US, he and his arrangers aimed to protect his privacy. Although swamped with telegrams and invitations to receive awards or speak publicly, he declined them all. After arriving in New York City, Einstein was taken to various places and events, including Chinatowna lunch with the editors of The New York Timesand a performance of Carmen at the Metropolitan Operawhere he was cheered by the audience on his arrival.
During the days following, he was given the keys to the city by Mayor Jimmy Walker and met the president of Columbia University, who described Einstein as "the ruling monarch of the mind". His friendship with Millikan was "awkward", as Millikan "had a penchant for patriotic militarism," where Einstein was a pronounced pacifist.
This aversion to war also led Einstein to befriend author Upton Sinclair and film star Charlie Chaplinboth noted for writing a dissertation guide pacifism.
Carl Laemmlehead of Universal Studiosgave Einstein a tour of his studio and introduced him to Chaplin. They had an instant rapport, with Chaplin inviting Einstein and his wife, Elsa, to his home for dinner.
Chaplin speculated that it was "possibly used as kindling wood by the Nazis. While at American universities in earlyhe undertook his third two-month visiting professorship at the California Institute of Technology in Pasadena. He and his wife Elsa returned to Belgium by ship in March, and during the trip they learned that their cottage was raided by the Nazis and his personal sailboat confiscated.
Upon landing in Antwerp on 28 March, he immediately went to the German consulate and surrendered his passport, formally renouncing his German citizenship. In AprilEinstein discovered that the new German government had passed laws barring Jews from holding any official positions, including teaching at universities. I must confess that the degree of their brutality and cowardice came as something of a surprise.
Einstein was now without a permanent home, unsure where he would live and work, and equally worried about the fate of countless other scientists still in Germany. He rented a house in De Haan, Belgium, where he lived for a few months. In late Julyhe went to England for about six weeks at the personal invitation of British naval officer Commander Oliver Locker-Lampsonwho had become friends with Einstein in the preceding years.
To protect Einstein, Locker-Lampson had two assistants watch over him at his secluded cottage outside London, with a photo of them carrying shotguns and guarding Einstein, published in the Daily Herald on 24 July British historian Martin Gilbert notes that Churchill responded immediately, and sent his friend, physicist Frederick Lindemannto Germany to seek out Jewish scientists and place them in British universities. Locker-Lampson also submitted a bill to parliament to extend British citizenship to Einstein, during which period Einstein made a number of public appearances describing the crisis brewing in Europe.
In October Einstein returned to the US and took up a position at the Institute for Advanced Study,   noted for having become a refuge for scientists fleeing Nazi Germany. Einstein was still undecided on his future. He had offers from several European universities, including Christ Church, Oxford where he stayed for three short periods between May and June and was offered a 5-year studentship,   but in he arrived at the decision to remain permanently in the United States and apply for citizenship.
The two would take long walks together discussing their work. Bruria Kaufmanhis assistant, later became a physicist. During this period, Einstein tried to develop a unified field theory and to refute the accepted interpretation of quantum physicsboth unsuccessfully. The letter is believed to be "arguably the key stimulus for the U. For Einstein, "war was a disease Einstein became an American citizen in Not long after settling into his career at the Institute for Advanced Study in Princeton, New Jerseyhe expressed his appreciation of the meritocracy in American culture when compared to Europe.
He recognized the "right of individuals to say and think what they pleased", without social barriers, and as a result, individuals were encouraged, he said, to be more creative, a trait he valued from his own early education.
Du Bois and was prepared to testify on his behalf during his trial in In Einstein visited Lincoln University in Pennsylvania, a historically black collegewhere he was awarded an honorary degree.
Lincoln was the first university in the United States to grant college degrees to African Americans ; alumni include Langston Hughes and Thurgood Marshall. Einstein gave a speech about racism in America, adding, "I do not intend to be quiet about it.
Einstein was a figurehead leader in helping establish the Hebrew University of Jerusalemwhich opened inand was among its first Board of Governors. Earlier, inhe was asked by the biochemist and president of the World Zionist OrganizationChaim Weizmannto help raise funds for the planned university.
Among those, he advised first creating an Institute of Agriculture in order to settle the undeveloped land. Einstein developed an appreciation for music at an early age, and later wrote: I often think dissertation environmental science music.
I short articles my daydreams in music. I see my life in terms of music I get most joy in life out of music. His mother played the piano reasonably well and wanted her son to learn the violinnot only to instill in him a love of music but also to help him assimilate into German culture.
According to conductor Leon BotsteinEinstein began playing when he was 5, although he did not enjoy it at that age. He taught himself to play without "ever practicing systematically", he said, deciding that "love is a better teacher than a sense of duty. Music possessed an unusual meaning for this student. Although the idea of becoming a professional musician himself was not on his mind at any time, among those with whom Einstein played chamber music were a few professionals, and he performed for private audiences and friends.
Einstein was deeply impressed by Mahatma Gandhi. He exchanged written letters with Gandhi, and called him "a role model for the generations to come" in a letter writing about him.
Einstein spoke of his spiritual outlook in a wide array of original writings and interviews. And one life is enough for me. He served on the advisory board of the First Humanist Society of New York and was an honorary associate of the Rationalist Associationwhich publishes New Humanist in Britain. For the seventy-fifth anniversary of the New York Society for Ethical Culturehe stated that the idea of Ethical Culture embodied his personal conception of what is most valuable and enduring in religious idealism.
On 17 AprilEinstein experienced internal bleeding caused by the rupture of an abdominal aortic aneurysmwhich had previously been reinforced surgically by Rudolph Nissen in Einstein refused surgery, saying, "I want to go when I want.
It is tasteless to prolong life artificially. I have done my share; it is time to go. I will do it elegantly. Robert Oppenheimer summarized his impression of Einstein as a person: There was always with him a wonderful purity at once childlike and profoundly stubborn. Throughout his life, Einstein published hundreds of books and articles. These four works contributed substantially to the foundation of modern physics and changed views on spacetime, and matter.
The four papers are:. Two papers he published in — thermodynamics attempted to interpret atomic phenomena from a statistical point of view. These papers were the foundation for the paper on Brownian motion, which showed that Brownian movement can be construed as firm evidence that molecules exist. His research in and was mainly concerned with the effect of finite atomic size on diffusion phenomena. Einstein returned to the problem of thermodynamic fluctuations, giving a treatment of the density variations in a fluid at its critical point.
Ordinarily the density fluctuations are controlled by the second derivative of the free energy with respect to the density. At the critical point, this derivative is zero, leading to large fluctuations. The effect of density fluctuations is that light of all wavelengths is scattered, making the fluid look milky white. Einstein relates this to Rayleigh scatteringwhich is what happens when the fluctuation size is much smaller than the wavelength, and which explains why the sky is blue.
This paper predicted that, when measured in the frame of a relatively moving observer, a clock carried by a moving body would appear to slow downand the body itself would contract in its direction of motion. This paper also argued that the idea of a luminiferous aether —one of the leading theoretical entities in physics at the time—was superfluous.
Einstein originally framed special relativity in terms of kinematics the study of moving bodies. InHermann Minkowski reinterpreted special relativity in geometric terms as a theory of spacetime. General relativity GR is a theory of gravitation that was developed by Einstein between and According to general relativitythe observed gravitational attraction between masses results from the warping of space and time by those masses.
General relativity has developed into an essential tool in modern astrophysics. It provides the foundation for the current understanding of black holesregions of space where gravitational attraction is so strong that not even light can escape.
As Einstein later said, the reason for the development of general relativity was that the preference of inertial motions within special relativity was unsatisfactory, while a theory which from the outset prefers no state of motion even accelerated ones should appear more satisfactory. In that article titled "On the Relativity Principle and the Conclusions Drawn from It", he argued that free fall is really inertial motion, and that for a free-falling observer the rules of special relativity must apply.
This argument is called the equivalence principle. In the same article, Einstein also predicted the phenomena of gravitational time dilationgravitational red shift and deflection of light. InEinstein published another article "On the Influence of Gravitation on the Propagation of Light" expanding on the article, in which he estimated the amount of deflection of light by massive bodies. Thus, the theoretical prediction of general relativity could for the first time be tested experimentally.
InEinstein predicted gravitational waves  ripples in the curvature of spacetime which propagate as wavestraveling outward from the source, transporting energy as gravitational radiation.
The existence of gravitational waves is possible under general relativity due to its Lorentz invariance which brings the concept of a finite speed of propagation of the physical interactions of gravity with it. By contrast, gravitational waves cannot exist in the Newtonian theory of gravitationwhich postulates that the physical interactions of gravity propagate at infinite speed.
While developing general relativity, Einstein became confused about the gauge invariance in the theory. He formulated an argument that led him to conclude that a general relativistic field theory is impossible. He gave up looking for fully generally covariant tensor equations, and searched for equations that would be invariant under general linear transformations only. In Junethe Entwurf "draft" theory was the result of these investigations. As its name suggests, it was a sketch of a theory, less elegant and more difficult than general relativity, with the equations of motion supplemented by additional gauge fixing conditions.
After more than two years of intensive work, Einstein realized that the hole argument was mistaken  and abandoned the theory in November InEinstein applied the general theory of relativity to the structure of the universe as a whole.
As observational evidence for a dynamic universe was not known at the time, Einstein introduced a new term, the cosmological constantto the field equations, in order to allow the theory to predict a static universe. Following the discovery of the recession of the nebulae by Edwin Hubble inEinstein abandoned his static model of the universe, and proposed two dynamic models of the cosmos, The Friedmann-Einstein universe of   and the Einstein—de Sitter universe of In many Einstein biographies, it is claimed that Einstein referred to the cosmological constant in later years as his "biggest blunder".
The astrophysicist Mario Livio has recently cast doubt on this claim, suggesting that it may be exaggerated. For the density to remain constant, new particles of matter must be continually formed in the volume from space. It thus appears that Einstein considered a steady-state model of the expanding universe many years before Hoyle, Bondi and Gold. General relativity includes a dynamical spacetime, so it is difficult to see how to identify the conserved energy and momentum. Einstein argued that this is true for fundamental reasons, because the gravitational field could be made to vanish by a choice of how to write a good graduate admissions essay. He maintained that the non-covariant energy momentum pseudotensor was in fact the best description of the energy momentum distribution in a gravitational field.
This approach has been echoed by Lev Landau and Evgeny Lifshitzand others, and has become standard. InEinstein collaborated with Nathan Rosen to produce a model of a wormholeoften called Einstein—Rosen bridges. These solutions cut and pasted Math homework help videos black holes to make a bridge between two patches.
If one end of a wormhole was positively charged, the other end would be negatively charged. These properties led Einstein to believe that pairs of particles hamlet essay prompts antiparticles could be described in this way.
In order to incorporate spinning point particles into general relativity, the affine connection needed to be generalized to include an antisymmetric part, called the torsion. This modification was made by Einstein and Cartan in the s.
The theory of general relativity has a fundamental law—the Einstein equations which describe how space curves, the geodesic equation which describes how particles move may be derived from the Einstein equations. Since the equations of general relativity are non-linear, a lump of energy made out of pure gravitational fields, like a black hole, would move on a trajectory which is determined by the Einstein equations themselves, not by a new law.
So Einstein proposed that the path of a singular solution, like a black hole, would be determined to be a geodesic from general relativity itself. This was established by Einstein, Infeld, and Hoffmann for pointlike objects without angular momentum, and by Roy Kerr for spinning objects. In a paper,  Einstein postulated that light itself consists of localized particles quanta.
He does not say much more, because he is not sure how the particles are related to the wave.
But he does suggest that this idea would explain certain narrative writing help results, notably the photoelectric effect. InEinstein proposed a model of matter where each atom in a lattice structure is an independent harmonic oscillator.
In the Einstein model, each atom oscillates independently—a series of equally spaced quantized states for each oscillator. Einstein was aware that getting the frequency of the actual oscillations would be difficult, but he nevertheless proposed this theory because it was a particularly clear demonstration that quantum mechanics could solve the specific heat problem in classical mechanics.
Peter Debye refined this model. Throughout the s, quantum mechanics expanded in scope to cover many different systems. After Ernest Rutherford discovered the nucleus and proposed that electrons orbit like planets, Niels Bohr was able to show that the same quantum mechanical postulates introduced by Planck and developed by Einstein would explain the discrete motion of electrons in atoms, and the periodic table of the elements.
Einstein contributed to these developments by linking them with the arguments Wilhelm Wien had made. Wien had shown that the hypothesis of adiabatic invariance of a thermal equilibrium state allows all the blackbody curves at different temperature to be derived from one another by a simple shifting process.
Einstein noted in that the same adiabatic principle shows that the quantity which is quantized in any mechanical motion must be an adiabatic invariant. Arnold Sommerfeld identified this adiabatic invariant as the action variable of classical mechanics. InEinstein received a description of a statistical model from Indian physicist Satyendra Nath Bosebased on a counting method that assumed that light could be understood as a gas of indistinguishable particles.
Einstein also published his own articles describing the model and its implications, among them the Bose—Einstein condensate phenomenon that some particulates should appear at very low temperatures. Although the patent office promoted Einstein to Technical Examiner Second Class inhe had not given up on academia.
Inhe became a Privatdozent at the University of Bern. This paper english essays for secondary students the photon concept although the name photon was introduced later by Gilbert N.
Lewis in and inspired the notion of wave—particle duality in quantum mechanics. Einstein saw this wave—particle duality in radiation as concrete evidence for his conviction that physics needed a new, unified foundation.
In a series of works completed from toPlanck reformulated his quantum theory and introduced the idea of zero-point energy in his "second quantum theory".
Soon, this idea attracted the attention of Einstein and his assistant Otto Stern. Assuming the energy of rotating diatomic molecules contains zero-point energy, they then compared the theoretical specific heat of hydrogen gas with the experimental data. The numbers matched nicely.
However, after publishing the findings, they promptly withdrew their support, because they no longer had confidence in the correctness of the idea of zero-point energy. Inat the height of his work on relativity, Einstein published an article in Physikalische Zeitschrift that proposed the possibility of stimulated emissionthe physical process that makes possible the maser and the laser.
This paper was enormously influential in the later development of quantum mechanics, because it was the first paper to show that the statistics of atomic transitions had simple laws. In another major paper from this era, Einstein gave a wave equation for de Broglie waveswhich Einstein suggested was the Hamilton—Jacobi equation of mechanics.
Einstein was displeased with modern quantum mechanics as it had evolved after Contrary to popular belief, his doubts were not due to a conviction that God "is not playing at dice. Einstein believed that a physical reality exists independent of our ability to observe it. In contrast, Bohr dissertation sur la videosurveillance his followers maintained that all we can know are the results of measurements and observations, and that it makes no sense to speculate about an ultimate reality that exists beyond our perceptions.
The Bohr—Einstein debates were a series of public disputes about quantum mechanics between Einstein and Niels Bohrwho were two of its founders. Their debates are remembered because of their importance to online paper writers philosophy of science.
InEinstein returned quantum mechanics, in particular to the question of its completeness, in the "EPR paper". No matter how far the two particles were separated, a precise position measurement on one particle would result in equally precise knowledge of the position of the other particle; likewise a precise momentum measurement of one particle would result in equally precise knowledge of the momentum of the other particle, without needing to disturb the other particle in any way.
Einstein rejected this second possibility popularly called "spooky action at a distance". Bell had delineated in The results of these and subsequent experiments demonstrate that quantum physics cannot be represented by any version of the picture of physics in which "particles are regarded as unconnected independent classical-like entities, each one being unable to communicate with the other after they have separated.
Although Einstein was wrong about local realism, his clear prediction of the unusual properties of its opposite, entangled quantum stateshas resulted in the EPR paper becoming among the top ten papers published in Physical Review.
