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.

Archived from the original on 6 March Retrieved 7 March We have explained the new beginnings that Poland had experienced in the few years before this, and there were strong nationalist feelings in the country. There is no doubt that Tarski was strongly influenced by these feelings and wished to be a Pole and not a Jew.

Both the name change and the change of religion made him more Polish. There was also the realisation that anti-Semitic views in the country made it almost impossible for a Jew to be appointed to a university post and Tarski, nearing the end of his doctoral studies, certainly wished to follow an academic career. Tarski's first paper was published in when he was only 19 years old.

In this paper he investigated set theory questions, and in fact set theory would be a continuing research interest for Tarski throughout his life. His doctoral studies were supervised by Lesniewski and he submitted his doctoral thesis for examination in In Tarski graduated with a doctorate, and became the youngest person ever to be awarded the degree by the University of Warsaw.

Tarski's first major results were published in when he began building on the set theory results obtained by Cantor , Zermelo and Dedekind. He published a joint paper with Banach in that year on what is now called the Banach -Tarski paradox. This is not a paradox at all, the only reason that it is given this name is that it is counter-intuitive.

The result proves that a sphere can be cut into a finite number of pieces and then reassembled into a sphere of larger size, or alternatively it can be reassembled into two spheres of equal size to the original one. Tarski taught logic at the Polish Pedagogical Institute in Warsaw from to then in that year he was appointed Docent in mathematics and logic at the University of Warsaw.

Given Tarski's Polish patriotism which we mentioned above, it may be relevant to note that Maria was a Roman Catholic and she had worked as a courier for the army during Poland's fight for independence. This was a time when Tarski's international reputation continued to grow. He visited the University of Vienna in February where he lectured to Menger 's colloquium.

In Tarski published The concept of truth in formalized languages which is his now famous paper on the concept of truth Not only does this paper provide a mathematically rigorous articulation of several ideas that had been developing in earlier mathematical logic, it also presents foundations on which later logic could be built. Tarski was awarded a fellowship to allow him to return to Vienna in January and he worked with Menger 's research group until June.

The Vienna Circle of Logical Positivists which flourished, particularly in the s in Vienna, had led to the development of the Unity of Science group and this group met in Paris in Tarski presented his ideas on truth in a lecture at this meeting. Niiniluoto, in [ 47 ] argues In defending Tarski against some of his critics, I wish to show how this account of truth can be formulated, understood, and further developed in a philosophically satisfactory way.

Tarski published On the concept of logical consequence in In this he claimed that the conclusion of an argument will follow logically from its premises if and only if every model of the premises be a model of the conclusion. This work on logical consequence has had a profound influence and has been discussed by many authors; see for example [ 5 ] , [ 13 ] , [ 23 ] , [ 36 ] , [ 53 ] , [ 56 ] , and [ 70 ].

In he published another classic paper, this time on the deductive method, which presents clearly his views on the nature and purpose of the deductive method, as well as considering the role of logic in scientific studies. It is hard to be certain why one candidate may be preferred to another in a competition for a chair so it is impossible to say with certainty that anti-Semitism played a role in the decision.

However, it is certainly fair to say that by Tarski had an outstanding international reputation but was still forced to support himself by teaching mathematics in a high school. It is certainly reasonable to believe that changing one's name and religion would not allow Jews to escape from the discrimination which was widespread throughout Europe at this time.

At Tarski had been in the United States for two weeks at the time. It was extremely fortunate for him that he was not in Poland when the German armies attacked, for there is no doubt that despite the change of name and religion, he would still have qualified as a Jew as far at the Nazi regime were concerned. By this time Tarski had two children, a son Jan and a daughter Ina, and both his wife and children had remained in Poland when he travelled to the United States in Tarski was successful in obtaining permission to remain in the United States, and he then tried, with the help of many European friends, to arrange for his family to escape and join him in the United States.

He failed to achieve this but fortunately all three survived the war and were able to join Tarski in However, his father, mother, brother and sister-in-law all died at the hands of the Nazis during the war. Certainly Tarski's life was saved by being in the United States but he still had to secure a job. Permanent posts were not easy to obtain since many outstanding academics had fled from Europe to the United States in the years immediately prior to the outbreak of war.

A philosophical debate examines the extent to which Tarski's theory of truth for formalized languages can be seen as a correspondence theory of truth. The debate centers on how to read Tarski's condition of material adequacy for a true definition. That condition requires that the truth theory have the following as theorems for all sentences p of the language for which truth is being defined:.

A new English translation of this paper, Tarski , highlights the many differences between the German and Polish versions of the paper and corrects a number of mistranslations in Tarski This publication set out the modern model-theoretic definition of semantic logical consequence, or at least the basis for it. Whether Tarski's notion was entirely the modern one turns on whether he intended to admit models with varying domains and in particular, models with domains of different cardinalities.

John Etchemendy stimulated much of the discussion about Tarski's treatment of varying domains. Tarski ends by pointing out that his definition of logical consequence depends upon a division of terms into the logical and the extra-logical and he expresses some skepticism that any such objective division will be forthcoming. Tarski's "What are Logical Notions?

It became the most cited paper in the journal History and Philosophy of Logic. In the talk, Tarski proposed demarcation of logical operations which he calls "notions" from non-logical. The suggested criteria were derived from the Erlangen program of the 19th-century German mathematician Felix Klein. The Erlangen program classified the various types of geometry Euclidean geometry , affine geometry , topology , etc.

A one-to-one transformation is a functional map of the space onto itself so that every point of the space is associated with or mapped to one other point of the space. So, "rotate 30 degrees" and "magnify by a factor of 2" are intuitive descriptions of simple uniform one-one transformations. Continuous transformations give rise to the objects of topology, similarity transformations to those of Euclidean geometry, and so on.

As the range of permissible transformations becomes broader, the range of objects one is able to distinguish as preserved by the application of the transformations becomes narrower. Similarity transformations are fairly narrow they preserve the relative distance between points and thus allow us to distinguish relatively many things e. Continuous transformations which can intuitively be thought of as transformations which allow non-uniform stretching, compression, bending, and twisting, but no ripping or glueing allow us to distinguish a polygon from an annulus ring with a hole in the centre , but do not allow us to distinguish two polygons from each other.

Tarski's proposal [ which? By domain is meant the universe of discourse of a model for the semantic theory of logic. If one identifies the truth value True with the domain set and the truth-value False with the empty set, then the following operations are counted as logical under the proposal:. In some ways the present proposal is the obverse of that of Lindenbaum and Tarski , who proved that all the logical operations of Bertrand Russell 's and Whitehead 's Principia Mathematica are invariant under one-to-one transformations of the domain onto itself.

The present proposal is also employed in Tarski and Givant Feferman raises problems for the proposal and suggests a cure: replacing Tarski's preservation by automorphisms with preservation by arbitrary homomorphisms. In essence, this suggestion circumvents the difficulty Tarski's proposal has in dealing with a sameness of logical operation across distinct domains of a given cardinality and across domains of distinct cardinalities.

Feferman's proposal results in a radical restriction of logical terms as compared to Tarski's original proposal. In particular, it ends up counting as logical only those operators of standard first-order logic without identity. Vann McGee provides a precise account of what operations are logical in the sense of Tarski's proposal in terms of expressibility in a language that extends first-order logic by allowing arbitrarily long conjunctions and disjunctions, and quantification over arbitrarily many variables.
