There are no reviews yet. The modified field equations predicted a static universe of closed curvature, in accordance with Einstein's understanding of Mach's principle in these years.

This model became known as the Einstein World or Einstein's static universe. Following the discovery of the recession of the galaxies by Edwin Hubble in , Einstein 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", based on a letter George Gamow claimed to have received from him.

The astrophysicist Mario Livio has cast doubt on this claim. In late , a team led by the Irish physicist Cormac O'Raifeartaigh discovered evidence that, shortly after learning of Hubble's observations of the recession of the galaxies, 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 determined from a Lagrangian with translation invariance , but 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.

In , Einstein collaborated with Nathan Rosen to produce a model of a wormhole , often called Einstein—Rosen bridges. These solutions cut and pasted Schwarzschild black holes to make a bridge between two patches. Because these solutions included spacetime curvature without the presence of a physical body, Einstein and Rosen suggested that they could provide the beginnings of a theory that avoided the notion of point particles.

However, it was later found that Einstein—Rosen bridges are not stable. 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. In general relativity, gravitational force is reimagined as curvature of spacetime.

A curved path like an orbit is not the result of a force deflecting a body from an ideal straight-line path, but rather the body's attempt to fall freely through a background that is itself curved by the presence of other masses. A remark by John Archibald Wheeler that has become proverbial among physicists summarizes the theory: Spacetime tells matter how to move; matter tells spacetime how to curve.

The geodesic equation covers the former aspect, stating that freely falling bodies follow lines that are as straight as possible in a curved spacetime. Einstein regarded this as an "independent fundamental assumption" that had to be postulated in addition to the field equations in order to complete the theory. Believing this to be a shortcoming in how general relativity was originally presented, he wished to derive it from the field equations themselves.

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. Accordingly, Einstein proposed that the field equations would determine the path of a singular solution, like a black hole, to be a geodesic.

Both physicists and philosophers have often repeated the assertion that the geodesic equation can be obtained from applying the field equations to the motion of a gravitational singularity , but this claim remains disputed. 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 in , with Robert Millikan 's detailed experiments on the photoelectric effect, and with the measurement of Compton scattering. Einstein concluded that each wave of frequency f is associated with a collection of photons with energy hf each, where h is the Planck constant. He did not say much more, because he was not sure how the particles were related to the wave.

But he did suggest that this idea would explain certain experimental results, notably the photoelectric effect. Lewis in In , Einstein 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. In , Einstein received a description of a statistical model from Indian physicist Satyendra Nath Bose , based 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. Einstein's sketches for this project may be seen in the Einstein Archive in the library of the Leiden University. Although the patent office promoted Einstein to Technical Examiner Second Class in , he had not given up on academia.

In , he became a Privatdozent at the University of Bern. This paper introduced the photon concept 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 to , Planck 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.

In , at the height of his work on relativity, Einstein published an article in Physikalische Zeitschrift that proposed the possibility of stimulated emission , the 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.

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 observed that de Broglie waves could explain the quantization rules of Bohr and Sommerfeld. 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 after , despite 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 Bohr , who were two of its founders.

Their debates are remembered because of their importance to the philosophy of science. Einstein never fully accepted quantum mechanics. While he recognized that it made correct predictions, he believed a more fundamental description of nature must be possible. Over the years he presented multiple arguments to this effect, but the one he preferred most dated to a debate with Bohr in Einstein suggested a thought experiment in which two objects are allowed to interact and then moved apart a great distance from each other.

The quantum-mechanical description of the two objects is a mathematical entity known as a wavefunction. But because of what would later be called quantum entanglement , measuring one object would lead to an instantaneous change of the wavefunction describing the other object, no matter how far away it is. Moreover, the choice of which measurement to perform upon the first object would affect what wavefunction could result for the second object.

Einstein reasoned that no influence could propagate from the first object to the second instantaneously fast. Indeed, he argued, physics depends on being able to tell one thing apart from another, and such instantaneous influences would call that into question. Because the true "physical condition" of the second object could not be immediately altered by an action done to the first, Einstein concluded, the wavefunction could not be that true physical condition, only an incomplete description of it.

A more famous version of this argument came in , when Einstein published a paper with Boris Podolsky and Nathan Rosen that laid out what would become known as the EPR paradox. Then, no matter how far the two particles were separated, a precise position measurement on one particle would imply the ability to predict, perfectly, the result of measuring the position of the other particle.

Likewise, a precise momentum measurement of one particle would result in an equally precise prediction for of the momentum of the other particle, without needing to disturb the other particle in any way. They argued that no action taken on the first particle could instantaneously affect the other, since this would involve information being transmitted faster than light, which is forbidden by the theory of relativity.

They invoked a principle, later known as the "EPR criterion of reality", positing that: If, without in any way disturbing a system, we can predict with certainty i. From this, they inferred that the second particle must have a definite value of both position and of momentum prior to either quantity being measured. But quantum mechanics considers these two observables incompatible and thus does not associate simultaneous values for both to any system.

Einstein, Podolsky, and Rosen therefore concluded that quantum theory does not provide a complete description of reality. In , John Stewart Bell carried the analysis of quantum entanglement much further. He deduced that if measurements are performed independently on the two separated particles of an entangled pair, then the assumption that the outcomes depend upon hidden variables within each half implies a mathematical constraint on how the outcomes on the two measurements are correlated.

This constraint would later be called a Bell inequality. Bell then showed that quantum physics predicts correlations that violate this inequality. Consequently, the only way that hidden variables could explain the predictions of quantum physics is if they are "nonlocal", which is to say that somehow the two particles are able to interact instantaneously no matter how widely they ever become separated.

Despite this, and although Einstein personally found the argument in the EPR paper overly complicated, [ ] [ ] that paper became among the most influential papers published in Physical Review. It is considered a centerpiece of the development of quantum information theory. Encouraged by his success with general relativity, Einstein sought an even more ambitious geometrical theory that would treat gravitation and electromagnetism as aspects of a single entity.

In , he described his unified field theory in a Scientific American article titled "On the Generalized Theory of Gravitation". Although most researchers now believe that Einstein's approach to unifying physics was mistaken, his goal of a theory of everything is one to which his successors still aspire. Einstein conducted other investigations that were unsuccessful and abandoned.

These pertain to force , superconductivity , and other research. In addition to longtime collaborators Leopold Infeld , Nathan Rosen , Peter Bergmann and others, Einstein also had some one-shot collaborations with various scientists. In , Owen Willans Richardson predicted that a change in the magnetic moment of a free body will cause this body to rotate.

This effect is a consequence of the conservation of angular momentum and is strong enough to be observable in ferromagnetic materials. These measurements also allow the separation of the two contributions to the magnetization: that which is associated with the spin and with the orbital motion of the electrons. The Einstein-de Haas experiment is the only experiment concived, realized and published by Albert Einstein himself.

It was lost among the museum's holdings and was rediscovered in 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, but the most promising of their patents were acquired by the Swedish company Electrolux. Einstein also invented an electromagnetic pump, [ ] sound reproduction device, [ ] and several other household devices.

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 years after her death she died in [ ].

Barbara Wolff, of the Hebrew University's Albert Einstein Archives , told the BBC that there are about 3, pages of private correspondence written between 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 of Jerusalem is the exclusive representative of that right. Mount Einstein in the Chugach Mountains of Alaska was named in In , Einstein was named Time 's Person of the Century. In , a survey of the top physicists voted for Einstein as the "greatest physicist ever", while a parallel survey of rank-and-file physicists gave the top spot to Isaac Newton , with Einstein second.

Physicist Lev Landau ranked physicists from 0 to 5 on a logarithmic scale of productivity and genius, with Newton and Einstein belonging in a "super league", with Newton receiving the highest ranking of 0, followed by Einstein with 0. Physicist Eugene Wigner noted that while John von Neumann had the quickest and acute mind he ever knew, the understanding of Einstein was deeper than von Neumann's, stating that: [ ].

But Einstein's understanding was deeper than even Jancsi von Neumann's. His mind was both more penetrating and more original than von Neumann's. And that is a very remarkable statement. Einstein took an extraordinary pleasure in invention. Two of his greatest inventions are the Special and General Theories of Relativity; and for all of Jancsi's brilliance, he never produced anything so original.

No modern physicist has. The year was labeled the " World Year of Physics ", and was also known as "Einstein Year", in recognition of Einstein's " miracle year " in Einstein became one of the most famous scientific celebrities after the confirmation of his general theory of relativity in In the period before World War 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".

Eventually he came to cope with unwanted enquirers by pretending to be someone else: Pardon me, sorry! Always I am mistaken for Professor Einstein. 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 in , he 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. None of the nominations in met the criteria set by Alfred Nobel , so the prize was carried forward and awarded to Einstein in Einsteinium , a synthetic chemical element, was named in his honor in , a few months after his death.

Stachel, John ; Martin J. Klein; A. Kox; Michel Janssen; R. Schulmann; Diana Komos Buchwald; et al. The Collected Papers of Albert Einstein. His father, Hermann Einstein, was a salesman and engineer who, with his brother, founded Elektrotechnische Fabrik J. Einstein had one sister, Maja, born two years after him. Einstein attended elementary school at the Luitpold Gymnasium in Munich.

He also had what were considered speech challenges. However, he developed a passion for classical music and playing the violin, which would stay with him into his later years. Toward the end of the s, Max Talmud, a Polish medical student who sometimes dined with the Einstein family, became an informal tutor to young Einstein. Hermann relocated the family to Milan, Italy, in the mids after his business lost out on a major contract.

Einstein was eventually able to gain admission into the Swiss Federal Institute of Technology in Zurich, specifically due to his superb mathematics and physics scores on the entrance exam. He was still required to complete his pre-university education first and thus attended a high school in Aarau, Switzerland, helmed by Jost Winteler. Einstein later renounced his German citizenship and became a Swiss citizen at the dawn of the new century.

The maximum score of the current version is , with an IQ of or higher ranking in the 99 th percentile. Magazine columnist Marilyn vos Savant has the highest-ever recorded IQ at and was featured in the Guinness Book of World Records in the late s. However, Guinness discontinued the category because of debates about testing accuracy.

After graduating from university, Einstein faced major challenges in terms of finding academic positions, having alienated some professors over not attending class more regularly in lieu of studying independently. Einstein eventually found steady work in after receiving a referral for a clerk position in a Swiss patent office. While working at the patent office, Einstein had the time to further explore ideas that had taken hold during his university studies and thus cemented his theorems on what would be known as the principle of relativity.

Two focused on the photoelectric effect and Brownian motion. The theory explains that space and time are actually connected, and Einstein called this joint structure space-time. Einstein considered this theory the culmination of his life research. It also offered a more expansive, nuanced explanation of how gravitational forces worked. Today, the theories of relativity underpin the accuracy of GPS technology, among other phenomena.

Even so, Einstein did make one mistake when developing his general theory, which naturally predicted the universe is either expanding or contracting. His later theories directly contracted this idea and asserted that the universe could be in a state of flux. Then, astronomer Edwin Hubble deduced that we indeed inhabit an expanding universe. This equation suggested that tiny particles of matter could be converted into huge amounts of energy, a discovery that heralded atomic power.

Famed quantum theorist Max Planck backed up the assertions of Einstein, who thus became a star of the lecture circuit and academia, taking on various positions before becoming director of the Kaiser Wilhelm Institute for Physics today is known as the Max Planck Institute for Physics from to In , Einstein won the Nobel Prize in Physics for his explanation of the photoelectric effect, since his ideas on relativity were still considered questionable.

Einstein married Mileva Maric on January 6, While attending school in Zurich, Einstein met Maric, a Serbian physics student. In particular, he loved music. He wrote that if he had not been a scientist, he would have been a musician. Einstein played the violin to a high standard. I live my daydreams in music. I see my life in terms of music… I get most joy in life out of music.

Einstein died in , at his request his brain and vital organs were removed for scientific study. Citation: Pettinger, Tejvan. Updated 2nd March Albert Einstein — His Life at Amazon.
