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.

That way, he could wake up before hitting the second stage of sleep—a hypnagogic process believed to boost creativity and capture sleep-inspired ideas. Although sleep was important to Einstein, socks were not. He was famous for refusing to wear them.

According to a letter he wrote to future wife Elsa, he stopped wearing them because he was annoyed by his big toe pushing through the material and creating a hole. One of the most recognizable photos of the 20 th century shows Einstein sticking out his tongue while leaving his 72 nd birthday party on March 14, According to Discovery.

Tired from doing so all night, he refused and rebelliously stuck his tongue out at the crowd for a moment before turning away. UPI photographer Arthur Sasse captured the shot. Einstein was amused by the picture and ordered several prints to give to his friends. He was taken to the hospital for treatment but refused surgery, believing that he had lived his life and was content to accept his fate.

I have done my share, it is time to go. I will do it elegantly. He was able to photograph the office just as Einstein left it. However, during his life, Einstein participated in brain studies, and at least one biography claimed he hoped researchers would study his brain after he died. In keeping with his wishes, the rest of his body was cremated and the ashes scattered in a secret location.

According to The New York Times , the researchers believe it might help explain why Einstein was so intelligent. Rorke-Adams said she received the brain slides from Harvey. Einstein has also been portrayed on screen. Walter Matthau portrayed Einstein in the fictional comedy I. A much more historically accurate depiction of Einstein came in , when he was the subject of the first season of Genius , a part scripted miniseries by National Geographic.

Johnny Flynn played a younger version of the scientist, while Geoffrey Rush portrayed Einstein in his later years after he had fled Germany. Ron Howard was the director.

In this infamous equation, E stands for energy, m represents mass and c is the constant speed of light.

In , Einstein published four papers outlining his theory of general relativity, which updated Isaac Newton's laws of gravity by explaining that the force of gravity arose because massive objects warp the fabric of space-time. The theory was validated in , when British astronomer Arthur Eddington observed stars at the edge of the sun during a solar eclipse and was able to show that their light was bent by the sun's gravitational well, causing shifts in their perceived positions.

In , he won the Nobel Prize in physics for his work on the photoelectric effect, though the committee members also mentioned his "services to Theoretical Physics" when presenting their award. The decision to give Einstein the award was controversial because the brilliant physicist was a Jew and a pacifist.

Anti-Semitism was on the rise and relativity was not yet seen as a proven theory, according to an article from The Guardian. He renounced his German citizenship and moved to the United States to become a professor of theoretical physics at Princeton, becoming a U. During this era, other researchers were creating a revolution by reformulating the rules of the smallest known entities in existence.

The laws of quantum mechanics had been worked out by a group led by the Danish physicist Niels Bohr , and Einstein was intimately involved with their efforts. Bohr and Einstein famously clashed over quantum mechanics. Bohr and his cohorts proposed that quantum particles behaved according to probabilistic laws, which Einstein found unacceptable, quipping that " God does not play dice with the universe.

After he retired in , Einstein spent most of his later years trying to unify gravity with electromagnetism in what's known as a unified field theory. Einstein died of a burst blood vessel near his heart on April 18, , never unifying these forces. Einstein's body was cremated and his ashes were spread in an undisclosed location, according to the American Museum of Natural History.

But a doctor performed an unauthorized craniotomy before this and removed and saved Einstein's brain. Einstein's archetypal boffin persona, firmly lodged in popular culture, is well-earned. His ideas and theories were so shockingly revolutionary, he changed the way the Universe was imagined, not just once, but several times. Albert Einstein was proclaimed a genius while still in his 20s.

But his later work was dominated by a fruitless search for a unified theory and increasing isolation from mainstream physics. So why are we still obsessed with him? Aged just four, they sent him out to explore the local area on his own. Aged five, his father gave him a compass to play with. He was captivated by the motion of the needle. This was the genesis of his interest in science.

Much later, his theories would be used to explain that motion. After his parents moved to Italy for better job prospects, the teenage Einstein remained in Germany to finish his education. Despite his obvious capabilities in science and maths, his tendency to rebel against the prescriptive nature of school, where everything was unthinkingly memorised, led to some teachers giving him bad reports.

After failing the entrance exam for a Zurich technical college, Einstein studied a new syllabus at school, and entered college on his second attempt. Once there, he gained a reputation for missing classes and wasting time discussing science with friends in local cafes. At 17, he renounced his German citizenship in order to avoid military service.

For the next four years, Einstein was not the citizen of any country. This showed that measurements of space and time were relative to motion and subsequently forced physicists to re-evaluate some of their most basic concepts. Einstein would later be awarded the Nobel Prize for one of the other papers, where he explained photoelectric effect.

Brian Cox demonstrates time dilation, which is predicted by special relativity. It was not until that Einstein was finally offered an academic post — as a professor at the University of Zurich.
