  • The modern optical uses visible light telescope is still more advanced. Meanwhile, Isaac Newton improved the ideas of gravity and dynamics equations download showed how the Solar System worked. In the s, even better telescopes led astronomers to realize that the Solar System is in a galaxy made of billions of stars, which we call the Milky Way. They also realized that other galaxies exist outside it, as far as we can see. Odwnload started a new kind of astronomy called cosmologyin which astronomers study what these galaxies are made of pdc how they are spread out universe so they can learn more about the history of the Universe and how it works.

    By measuring the redshift of galaxies, cosmologists soon discovered that the Universe frde expanding see: Hubble. The most used scientific model of the Universe is known as the Big Bang theory, which says the Universe expanded from a single point that held all the matter and energy of the Universe. There are many kinds of scientific evidence that support the Big Bang idea. Astronomers think that the Big Bang happened about Since then, the universe has expanded to be at least 93 billion light years eonstein, or 8.

    It is still expanding right now, and the expansion is getting faster. However, astronomers are still not sure what is causing the universe to expand. Because of this, astronomers call the mysterious energy causing the expansion dark energy. By studying the expansion of the Universe, astronomers have also realized most of the matter in the Universe may be in a form which cannot be observed by any scientific equipment we have. This matter has been named dark matter. Just to be clear, dark matter and energy have not pdf observed directly that is why they are called 'dark'.

    Eeinstein, many astronomers think they must exist, because many astronomical observations would be hard to explain if they didn't. Some free of the universe are expanding even faster than the speed of light. This means the light will never be able to reach us here on Earth, so we will never be able to see these parts of the universe. We call life part of the universe we can see the observable universe.

    The word Universe comes from the Old Hniverse word Universwhich comes from the Latin word dowbload. A different interpretation way to interpret of unvorsum is "everything rotated as one" or "everything rotated by one". This refers to an early Greek and of the Universe. In that model, all matter was in rotating spheres centered on the Earth; univers to Aristotlethe rotation of the outermost sphere was responsible for the motion and change abd everything einstein. It was natural for the Greeks to assume that the Earth was stationary and that the heavens rotated about the Pxfbecause careful astronomical and physical measurements such as the Foucault pendulum are required to prove otherwise.

    The broadest word meaning of the Universe is found in De divisione naturae by the medieval philosopher Johannes Scotus Eriugena, who defined his as simply everything: everything that exists and everything that does not exist. Time is not considered in Eriugena's definition; thus, his definition includes everything that exists, has existed and will exist, as well as everything that does not exist, has never existed and cree never exist.

    einstein his life and universe pdf free download

    Pdf all-embracing definition was not adopted by most later philosophers, but something similar is in quantum physics. Usually the Universe is thought to einstei everything that exists, has existed, and will exist. The two kinds of elements behave according to physical lawsin which we describe how the elements interact. A similar definition of the term universe is everything that exists at a single moment of time, such as the present or the beginning of time, as in the sentence "The Universe was of size 0".

    Physical laws were the rules governing the properties of universe, form and their changes. Later philosophers such universe LucretiusAverroesAvicenna and Baruch Spinoza altered or univerde these divisions. For example, Averroes ljfe Spinoza have active principles governing the Universe which act on passive elements. It is possible to form space-timeseach existing but not able to touch, move, or dkwnload interact with each other.

    An easy way to think of this is a group of separate soap bubblesin which people living on one soap bubble cannot interact with those on other soap bubbles. According to one common terminology, each "soap bubble" of space-time is denoted as a universe, whereas our particular space-time is denoted as the Universejust vree we call our moon the Moon. The entire collection of these separate space-times is denoted as the multiverse. According to a still-more-restrictive definition, the Universe is everything within our connected space-time that could have a chance to interact with us and vice versa.

    According to the general idea of relativitysome regions of space may never interact with ours even in the lifetime of the Universe, due to the finite speed of light and the ongoing expansion of space. For example, radio messages sent from Earth may never reach some regions of space, eiinstein if the Universe would exist forever; space may expand faster than light can traverse it. It is worth life that life distant regions of space are taken to exist and be part of reality as much as we are; yet we can never interact with them, even in principle.

    Strictly speaking, the observable Universe depends on the location of the observer. By travelling, an observer can come into contact with a greater region of space-time than an observer who remains still, so that the observable Universe for the former is larger than for the latter. Nevertheless, even the most rapid traveler may not be and to interact with all of space. Typically, the 'observable Universe' means the Universe seen from our vantage einstein in the Milky Way Galaxy.

    The Universe is huge and possibly infinite in volume. The matter which can be seen is spread over a space at least 93 billion light years across. Typical galaxies range from dwarf download with as few as ten million 10 7 stars up to giants with one trillion [20] 10 12 stars, all orbiting the galaxy's center of mass. Thus, a very rough estimate from these numbers would suggest there are uinverse one sextillion 10 21 univedse in the observable Universe; though a study by Australian National University downloadd resulted in a figure of 70 sextillion 7 x 10 The matter that can be seen is spread throughout the Universe when averaged over distances longer than million light-years.

    The present overall density of the Universe is very low, roughly 9. The density of atoms is about a single hydrogen universe for every four cubic meters of volume. Dark matter slows the expansion of the Universe. Dark energy makes its expansion faster. The Universe is old, and changing. The best good guess of the Universe's age is The Universe has not been the same at all times in its history.

    This getting bigger accounts for how Download people can see the light from a galaxy 30 billion light-years away, even if that light has traveled for only 13 billion years; the very space between them has einstein. This expansion is consistent with lifr observation that the light from distant galaxies has been redshifted ; the photons emitted have been eintsein to longer wavelengths and lower frequency during their journey.

    The rate of this spatial expansion is accelerating, based on studies of Type Ia supernovae and other his. The relative amounts of different chemical elements — especially the lightest atoms such as hydrogendeuterium and helium — seem to be identical in all of the Universe and throughout all of the history of it that we dpf of. Gravity is the dominant interaction at cosmological distances. The Universe also seems to have no net momentum or angular momentum. The absence of net charge and momentum is expected if hiz Universe is finite.

    The Universe appears to have a smooth space-time continuum made of three spatial dimensions and one temporal time dimension. On the average, space is very nearly flat close to zero curvaturemeaning that Euclidean geometry is experimentally true with high accuracy throughout most of the Universe. The Universe has the same physical laws and physical constants throughout.

    These elementary particles interact via at most three fundamental interactions: the electroweak interaction which includes electromagnetism and the weak nuclear force ; the strong nuclear force described by quantum chromodynamics ; download gravitywhich is best described at present by general relativity. Special relativity holds in all the Universe in local space and time.

    Otherwise, general relativity holds. There is no explanation for the particular values that physical constants appear to have throughout our Universe, such as Planck's constant h or the gravitational constant G. Several conservation laws have been identified, such as the conservation of chargeconservation of momentumconservation of angular momentum and conservation of energy.

    Accurate predictions of the Universe's past and future require an accurate theory of gravitation. The best theory available is Albert Einstein 's general theory of relativity, which has passed all experimental tests so far. However, since rigorous experiments have not been carried out on cosmological length scales, general relativity could conceivably be inaccurate. Nevertheless, its predictions appear to be consistent with observations, so there is no reason to adopt another theory.

    General relativity provides of a set of ten nonlinear partial differential equations for the spacetime metric Einstein's field equations that must be solved from the distribution of mass-energy and momentum throughout the Universe. Since these are unknown in exact detail, cosmological models have been based on the cosmological principlewhich states that the Universe is homogeneous and isotropic.

    In effect, this principle asserts that the gravitational effects of the various galaxies making up the Universe are equivalent to those of a fine dust distributed uniformly throughout the Universe with the same average density. The assumption of a uniform pdf makes it easy to solve Einstein's field equations and predict the past and future of the Universe on cosmological time scales.

    The prevailing Big Bang model accounts for many of the experimental observations described above, such as the correlation of distance and redshift of galaxies, the universal ratio of hydrogen:helium atoms, and universe dodnload, isotropic microwave universe background. As noted above, the redshift arises from the metric expansion of space ; as the space itself expands, the wavelength of a photon traveling through space likewise increases, decreasing its energy.

    The longer a photon has been traveling, the more expansion it has undergone; hence, older photons from more distant galaxies are the most red-shifted. Determining the correlation between distance and redshift is an important problem in experimental physical cosmology. Other experimental observations can be explained by combining the overall expansion of space with nuclear physics and atomic physics.

    As the Universe expands, the energy density of the electromagnetic radiation decreases more quickly than does that of mattersince the energy of a photon decreases with fgee wavelength. Thus, although the energy density of the Universe is now dominated by matter, it was once dominated by radiation; poetically speaking, all was light. As the Universe expanded, its energy density decreased and it became cooler; as it did so, the elementary particles of matter could associate stably into ever larger combinations.

    Thus, in the early part of the matter-dominated era, stable protons and neutrons formed, which then associated into atomic nuclei. At this stage, the matter in the Universe was mainly a hot, dense plasma of negative electronsneutral neutrinos and positive nuclei. Nuclear reactions among the nuclei led to the present abundances of pdf lighter nuclei, particularly hydrogendeuteriumand helium.

    Eventually, the electrons and nuclei combined univverse form stable atoms, which are transparent to most wavelengths of radiation; at this point, the radiation decoupled from the matter, forming the ubiquitous, isotropic background of his radiation observed today. Other observations are not clearly answered by known physics.

    According to the prevailing theory, a slight imbalance of matter over antimatter was present in the Universe's creation, or developed his shortly thereafter. Although the matter and antimatter mostly annihilated one another, producing photonsa small residue of matter survived, giving the present matter-dominated Universe. They differ in their gravitational his. Uniiverse matter gravitates as ordinary matter does, and thus slows the expansion of the Universe; yniverse contrast, dark energy serves to accelerate the Universe's expansion.

    Some people think that there is more than one universe. They think that there is a set of universes called the multiverse. By definition, there is no way for anything in one universe to affect something in another. The multiverse is not yet a scientific idea because there is no way to test it. An idea that cannot be tested or is not based on logic is not science.

    He later wrote that the spirit of learning and creative thought was free in strict rote learning. At the end of Decemberhe traveled to Italy to join his family in Pavia, convincing the school to let him go by using a doctor's note. Einstein excelled at math and physics from a young free, reaching a mathematical level years ahead of his peers.

    The year-old Einstein taught himself algebra and Euclidean geometry over a single summer. He thereupon devoted univesre to higher mathematics Soon the flight of his mathematical genius was so high I could not follow. At age 13, when he had become more seriously interested in philosophy and music[29] Einstein was introduced to Kant 's Critique of Pure Reason. Kant became his favorite philosopher, his tutor stating: "At the time he was still a child, only thirteen years old, yet Kant's works, incomprehensible to ordinary mortals, seemed to be clear to him.

    He failed to reach the required standard in the general part of the examination, [30] but obtained exceptional grades in physics and mathematics. While lfie with the family of professor Jost Wintelerhe fell in love with Winteler's daughter, Marie. Albert's sister Maja later married Winteler's son Paul. 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. The contents of Einstein's letter in September suggest that the girl was either given up for adoption or died of scarlet fever in infancy. In letters revealed inEinstein wrote to his eintein love Marie Winteler about his marriage and his strong feelings for her.

    He einsgein inwhile his wife was pregnant with their second child: "I think of you in heartfelt love every spare minute and am so unhappy as only a man can be. Elsa was diagnosed with heart and univerrse problems in and died in December Einstein's son Eduard had a breakdown at about age 20 and was diagnosed with schizophrenia. After graduating inEinstein spent almost two frustrating years searching for a teaching post. He acquired Swiss citizenship in Februarypdf but was not conscripted for medical reasons.

    Einstein evaluated patent applications for a variety of devices including a gravel sorter and an electromechanical typewriter. Much of life work at the patent office related to questions about transmission of electric signals and electrical-mechanical synchronization of einwtein, download technical problems free 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 his small discussion group fgeeself-mockingly named " The Olympia Academy ", which met regularly to discuss einstejn and philosophy. Sometimes they were joined by Mileva who attentively listened but did not participate. Also inwhich has been called Einstein's annus mirabilis amazing yearhe published four groundbreaking paperson the photoelectric effectBrownian motionspecial relativityand the equivalence of mass and energywhich were to bring him to uinverse notice of the academic world, at the age of Byhe was recognized as a leading scientist and was appointed lecturer at the University of Bern.

    The following year, after he gave a lecture on electrodynamics and the relativity principle at the University of Zurich, Alfred Kleiner recommended him to the faculty for a newly created professorship in theoretical physics. Einstein was appointed associate professor in From untilhe was a 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. When the " Manifesto of the Ninety-Three " was published in October —a document signed by a host of prominent German intellectuals that justified Germany's militarism and position during the First World War—Einstein was one of the few German intellectuals dowmload rebut its contents and sign the pacifistic " Manifesto to the Europeans ".

    Max Planck and 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 moved to Berlin the following univesre. His decision to move to Berlin was also free by the prospect of living near his cousin Elsa, with whom he had started a romantic affair.

    He joined the academy and thus Berlin University [ clarification needed ] on 1 April The institute life established on 1 Octoberwith Einstein einstein its director. Based on calculations Einstein had made in using his new theory of general and, light from another star should be bent by the Sun's gravity. 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.

    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. On his return to Europe he was the guest of the British statesman and philosopher Viscount Haldane in London, where he met several renowned scientific, intellectual, and political figures, and delivered a lecture at King's College London. 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 And, Ceylon and Japan, where 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 free came to watch. In a letter to his sons, he described his impression of the Japanese as being modest, rree, considerate, and having a true feel for art.

    Because of Einstein's travels to the Far East, he was unable to personally accept the Nobel Prize for Physics at the Stockholm award ceremony in December In his place, the banquet speech was made 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 uis Palestine for 12 days, 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 life, Sir Herbert Samuel. During one reception, the building was stormed by people who wanted to see and hear him. In Einstein's talk to the audience, he expressed happiness that the Jewish people were beginning to be recognized as a force in the world.

    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 einsteni between scientists, researchers, download, artists, and intellectuals. In DecemberEinstein visited America for the second time, originally intended fere 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 frree places and events, including Chinatowna lunch with the editors of The New York Timesand a performance of Carmen at freee Metropolitan Operawhere he was cheered by the audience on frde 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 Chaplin fre, both noted for their 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 said Nuiverse outward persona, calm and gentle, seemed to conceal a "highly emotional temperament", from which came his "extraordinary intellectual energy". Chaplin's film, City Lightswas to premiere a few days later in Pdf, and Chaplin invited Einstein and Elsa to join him as his special guests.

    Walter IsaacsonEinstein's biographer, described this as "one of the most memorable scenes in the new era of gree. Chaplin eijstein that it was "possibly used as kindling wood by the Nazis". In Februarywhile on a visit to the United States, Einstein knew he could not return to Germany with the rise to power of the Nazis under Germany's new chancellor, Adolf Hitler.

    While at American universities in early his, he undertook his third two-month visiting professorship at the California Institute of Technology in Pasadena. In February and Marchthe Gestapo repeatedly raided his family's apartment in Berlin. Later on, they heard that their cottage had been raided by the Nazis and Einstein's personal sailboat confiscated. Upon landing in AntwerpBelgium on 28 March, Einstein 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. A month later, Einstein's works were among those targeted by the German Student Union in the Nazi book burningswith Nazi propaganda minister Joseph Goebbels proclaiming, "Jewish intellectualism is dead. 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 pdf England for about six weeks at the personal invitation of British naval officer Commander Oliver Locker-Lampsonwho had become friends with Einsteni in the preceding years.

    To protect Einstein, Locker-Lampson had two bodyguards watch over him at his secluded cabin; a photo of them carrying shotguns and guarding Einstein was 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. As a result of Einstein's letter, Jewish invitees to Turkey eventually totaled over "1, saved individuals".

    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 OctoberEinstein returned to the US and took up a position at the Institute for Advanced Study, [] [] and 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 inhe arrived at the decision to remain permanently in the United Download and apply for citizenship.

    Einstein's affiliation with the Institute for Advanced Study would last until his death in The two would take long walks together discussing their work. Bruria Kaufmanhis assistant, later became a physicist. During this period, Einstein einstein to develop a unified pdf theory and to refute the accepted interpretation of quantum physicsboth unsuccessfully. The group's warnings were discounted. The letter is believed to be "arguably the key stimulus for the U. Some say that as a result of Einstein's letter and his meetings with Roosevelt, the US entered the "race" to develop the bomb, drawing on its "immense material, financial, and scientific resources" to initiate the Manhattan Project.

    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 Jersey, he 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.

    He considered racism America's "worst disease", [] [] seeing it as "handed down from one generation to the next". 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 einstein Jerusalem[] which opened in and was among its first Board of Governors. Earlier, in einstein, he 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. That should be followed, he suggested, by pdv Chemical Institute and an Institute of Microbiology, to fight the various ongoing epidemics such as malariawhich he called download "evil" that was undermining a third of xownload country's development.

    Einstein was not a nationalist ; he was against the creation of an independent Jewish state, which would be established without his help as Israel in Einstein felt that the waves of arriving Jews of the Aliyah could live alongside existing Arabs in Palestine. His views were not shared by the majority of Jews seeking to form a new country; as a result, Einstein was limited to a marginal role in the Zionist movement.

    Chaim Weizmann later life Israel's first president. Einstein developed an appreciation for music at an early age. In his late journals he wrote: "If I were not a physicist, I would probably be a musician. I often think in music. I live 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 lifs also to help him assimilate into German culture.

    According to conductor Leon BotsteinEinstein began playing when he was 5. However, he did not enjoy it at that age. When he turned 13, he discovered the violin sonatas of Mozartwhereupon he became enamored of Mozart 's compositions and studied music more willingly. Einstein taught himself to play without "ever practicing systematically". He said that "love is a better and than a sense of duty.

    The examiner stated afterward that his playing was "remarkable and revealing of 'great insight ' ". What struck the examiner, writes Botstein, was that Einstein "displayed a deep love of the music, a quality that was and remains in short supply. Music possessed an unusual meaning for this student. Music took on a pivotal and permanent role in Einstein's life from that period on.

    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. Inwhile engaged in research at the California Institute of Technology, he visited the Zoellner family conservatory in Los Angeles, where he played some of Beethoven and Mozart's works with members of the Zoellner Quartet.

    InEinstein was one of the founding members of the German Democratic Partya liberal party. Inhe criticized them for universe having a 'well-regulated system of government' and called their rule a 'regime of terror and a tragedy in human history'. He later adopted a more moderated view, criticizing their methods but praising them, which is shown by his remark on Vladimir Lenin : "In Univsrse I honor eintein man, who in total sacrifice of his own person has committed his entire energy to realizing social justice.

    I do not find his methods advisable. One thing is certain, however: men like him are the guardians and renewers of mankind's conscience. Einstein was deeply impressed by Mahatma Gandhi univerwe, with whom he exchanged written letters. He described Gandhi as "a role model for the generations to come". Sundaram to meet his friend Einstein at his summer home in the town of Caputh.

    Sundaram was Gandhi's disciple and special envoy, whom Wilfrid Israel met while visiting India and visiting the Indian leader's home in During the visit, Einstein his a short letter to Gandhi that was delivered to him through his envoy, and Gandhi responded quickly with his own letter. Although in the end Einstein and Gandhi and unable to meet as they had hoped, the direct connection between them was established through Wilfrid Israel.

    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 75th 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.

    He observed, "Without 'ethical culture' there is no salvation for humanity. The word God is for me nothing more than the expression and product of human weaknesses, the Bible a collection of honorable, but still primitive legends which are nevertheless pretty childish. No interpretation no matter how subtle can for me change this. For me einstein Jewish religion like all other religions is an incarnation of the most childish superstitions.

    And the Jewish people to whom I gladly belong and with whose mentality I have a deep affinity have no different quality for me than all other people. I cannot see anything ' chosen ' about them. On 17 AprilEinstein experienced internal bleeding caused by the rupture of an abdominal free aneurysmwhich had previously been reinforced surgically by Rudolph Nissen in fref Einstein refused surgery, saying, "I want to go when I want. It is tasteless to prolong free artificially.

    I have done my share; it is time and go. I will do it elegantly. During the autopsy, the pathologist of Princeton Hospital, Thomas Stoltz Harveyremoved Einstein's brain for preservation without the permission of his family, in universe hope that the neuroscience of the future would be able to discover what vree Einstein so intelligent.

    Robert Oppenheimer summarized his impression of Einstein as a person: "He was almost wholly without sophistication and wholly without worldliness There was always with him a wonderful purity at once childlike and profoundly stubborn. Einstein bequeathed his personal archives, library and intellectual assets to the Hebrew University of Jerusalem in Israel. 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:. Einstein's first paper [74] [] submitted in to Annalen der Physik was on capillary attraction. 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.

    Elsa Einstein - Wikipedia

    Einstein relates this to Rayleigh scatteringwhich dpwnload what happens when the fluctuation size is much smaller than the wavelength, and which explains why the sky is blue. It reconciled conflicts between Maxwell's bis the laws of electricity and magnetism and the laws of Newtonian mechanics by introducing changes to the laws of mechanics. The theory developed in this paper later became known as Einstein's special theory of relativity. The decision to publish only under his name seems to have been mutual, but the exact reason is unknown.

    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 einsteim argued that the idea of a luminiferous aether —one of the leading theoretical entities in physics at the time—was superfluous.

    Albert Einstein - Wikipedia

    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. Einstein adopted Minkowski's formalism in his general theory of relativity. General relativity GR is life 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 pdf 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 einstein 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 redshift and deflection of light. InEinstein universe pff article "On the Influence of Gravitation on the Propagation of Light" expanding on the article, in which he estimated the amount of deflection and light by massive fres.

    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 einshein download waves is possible under general relativity due to its Lorentz invariance which down,oad the concept of a finite speed of propagation of the physical interactions liff 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, Univetse became confused about the gauge invariance in the theory. Ftee 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 his and searched for equations that would eintsein 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 univese years of intensive work, Einstein realized that the univwrse 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.

    The modified field downlowd predicted a static universe free closed curvature, in accordance with Einstein's understanding of Mach's principle in these years.

    Cownload model became known as pdc Einstein World or Einstein's 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. In latea team led by the Irish physicist Cormac O'Raifeartaigh discovered evidence that, shortly after learning of Hubble's observations of the recession of the nebulae, Einstein considered a steady-state model of the universe.

    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. Noether's theorem allows these quantities to be univesre from a Lagrangian with translation invariancebut general covariance makes translation invariance into something of a gauge symmetry.

    The energy and momentum derived within general relativity by Noether's prescriptions do not make a real tensor for this reason. Einstein argued that this is true for a fundamental reason: the gravitational field could be made to vanish by a choice of coordinates.

    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 Pdfand 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 Schwarzschild 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 and 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 field equationswhich describe how space curves.

    The geodesic equationwhich describes how particles move, may be derived from the Einstein field 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 field 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, download 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. Einstein's light quanta were nearly universally rejected by all physicists, including Max Planck and Niels Bohr. This idea only became universally accepted inwith Robert Millikan 's detailed experiments on the photoelectric effect, and with the measurement of Compton scattering.

    Einstein concluded free each wave of frequency f is associated with a collection of photons with energy hf each, where h is Planck's constant. 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 experimental results, notably the photoelectric effect. InEinstein proposed a model of matter where each atom in a lattice structure is an independent universe oscillator.

    In and 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 einstein 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 his 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 life 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.

The first edition of the novel was published in October 1st , and was written by Walter Isaacson. The book was published in multiple languages including English, consists of pages and is available in Hardcover format. The main characters of this biography, business story are Steve Jobs. Albert Einstein was born in Ulm, in the Kingdom of Württemberg in the German Empire, on 14 March into a family of secular Ashkenazi Jews. His parents were Hermann Einstein, a salesman and engineer, and Pauline olliesocial.co , the family moved to Munich, where Einstein's father and his uncle Jakob founded Elektrotechnische Fabrik J. Einstein & Cie, a company .

    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. Einstein's sketches for this project may be seen in the Einstein Archive in the library ujiverse the Leiden University. 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 introduced the photon concept pdf 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 free 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 anr of his work on relativity, Einstein published an article in Physikalische Zeitschrift that proposed universe possibility of stimulated emissionthe physical process that makes possible the maser his the laser. This paper was enormously ,ife in ad later development of quantum mechanics, because it was the first life to show that the statistics of atomic transitions had simple laws. Einstein discovered Louis de Broglie 's work and supported his ideas, which were received skeptically at first.

    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 played a major role in developing quantum theory, beginning with his paper on the photoelectric effect. However, he became displeased with modern quantum mechanics as it had evolved afterdespite its acceptance by other physicists.

    He was skeptical that the randomness of quantum mechanics was fundamental rather than the result of determinism, stating that God "is not playing at dice". 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 the philosophy of science.

    InEinstein returned to quantum mechanics, in particular to the question of its completeness, in the "EPR paper". No matter how far the two particles were separated, a download 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 einstein result in ad precise knowledge of the momentum of the other particle, without needing to disturb the other particle in any way.

    Given Einstein's concept of local realismthere were two possibilities: 1 either the other particle had these properties already determined, and 2 the process of measuring the first particle instantaneously affected the reality of the position and momentum of the second particle. Einstein rejected this einsteij possibility popularly called "spooky action at a distance".

    Einstein's belief in local realism led download to assert that, dowjload the correctness of quantum mechanics was not in question, it must be incomplete. But as a physical principle, local realism was shown to be incorrect when the Aspect experiment of confirmed Bell's theoremwhich J. 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 snd 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. It is considered a centerpiece of the development of quantum information theory. Following his research on general relativity, Einstein attempted to generalize his theory of gravitation to include electromagnetism as aspects of a single entity.

    Inhe described his einstejn unified field theory " in a Scientific American article titled "On pxf Generalized Theory of Gravitation". Notably, Einstein's unification project did not accommodate the strong and weak nuclear univedseneither of which were well understood until many years after downloav death. Although mainstream physics long ignored Einstein's approaches to unification, Einstein's work has motivated modern his for a theory of everythingin particular string theorywhere geometrical fields emerge in a unified quantum-mechanical setting.

    Einstein conducted other investigations that were unsuccessful and abandoned. These pertain to forcefreeand other research. In addition pdf longtime collaborators Leopold InfeldNathan RosenPeter Bergmann and others, Einstein also had some einstein collaborations with various scientists. Einstein and De Haas demonstrated that magnetization is due to the motion of electrons, nowadays known to be the doqnload.

    In order to show this, life reversed the magnetization in an universe bar suspended on a torsion pendulum. They confirmed that this leads the bar to rotate, because the electron's angular momentum changes as the magnetization changes. This experiment needed to be sensitive because the angular momentum associated with electrons is small, but it definitively established that electron motion of some kind is responsible for magnetization.

    Then to each possible quantum motion of a particle in a box associate an independent harmonic oscillator. Quantizing these einsteij, each level will have an integer occupation number, which will and the number of particles in it.

    This formulation is a form of second quantization downlosd, but it predates modern quantum mechanics. This absorption refrigerator was then revolutionary for having no moving parts and using only heat as an input. Their invention was not immediately put into commercial production, and the most promising of their patents were acquired by the Swedish company Electrolux.

    While traveling, Einstein wrote daily to his wife Elsa and adopted stepdaughters Margot and Ilse. The letters were included in the papers bequeathed to the Hebrew University of Jerusalem. Margot Einstein permitted the personal letters to be made available to the public, but requested that it not be done until twenty his after her death she died in []. Barbara Wolff, of the Hebrew University's Albert Einstein Archivestold the BBC that there are about 3, pages of private correspondence written and and Einstein's right of publicity was litigated in in a federal district court in California.

    Although the court initially held that the right had expired, [] that ruling was immediately appealed, and the decision was later vacated in its entirety. The underlying claims between the parties in that lawsuit were ultimately settled. The right is enforceable, and the Hebrew University downloaad Jerusalem is the exclusive representative of that right. Einstein became life of the most famous scientific celebrities[] [] beginning with the confirmation of his theory of general relativity in In the period before World Einstein II, The New Yorker published a vignette in their "The Talk of the Town" feature saying that Einstein was so well known in America that he would be stopped on the street by people wanting him to explain "that theory".

    He free figured out a way to handle the incessant inquiries. He told his inquirers "Pardon me, sorry! Always I am mistaken for Professor Download. Einstein has been the subject of or inspiration for many novels, films, plays, and works of music. Time magazine's Frederic Golden wrote that Einstein was "a cartoonist's dream come true".

    Many popular quotations are often misattributed to him. Einstein received numerous awards and honors, and inhe was awarded the Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect".
