John Forbes Nash Jr.(English) John Forbes Nash, Jr.; June 13, 1928, Bluefield, West Virginia - May 23, 2015, New Jersey) was an American mathematician who worked in the fields of game theory and differential geometry.

Winner of the Nobel Prize in Economics in 1994 "for his analysis of equilibrium in the theory of non-cooperative games" (together with Reinhard Selten and John Harsanyi). He is best known to the general public for the biographical drama A Beautiful Mind by Ron Howard. A Beautiful Mind) about his mathematical genius and struggle with schizophrenia.

Biography

John Nash was born June 13, 1928 in Bluefield, West Virginia to a strict Protestant family. Her father worked as an electrical engineer at Appalachian Electric Power, and her mother worked as a school teacher for 10 years before her marriage. I studied average at school, but I didn’t like mathematics at all - at school it was taught boringly. When Nash was 14 years old, Eric T. Bell's The Makers of Mathematics fell into his hands. “After reading this book, I was able to prove Fermat's little theorem on my own, without outside help,” Nash writes in his autobiography. So his mathematical genius declared itself. But that was only the beginning.

Studies

After school, he studied at the Carnegie Polytechnic Institute (now the private Carnegie Mellon University), where Nash tried to study chemistry, took a course international economy, and then finally established himself in the decision to do mathematics. In 1947, after graduating from the institute with two diplomas - a bachelor's and a master's degree - he entered Princeton University. Nash Institute professor Richard Duffin provided him with one of the most concise letters of recommendation. It had a single line: "This man is a genius" (Eng. This man is a genius).

Work

At Princeton, John Nash heard about game theory, then only introduced by John von Neumann and Oscar Morgenstern. Game theory captured his imagination, so much so that at the age of 20, John Nash managed to create the foundations of the scientific method, which played a huge role in the development of the world economy. In 1949, the 21-year-old scientist wrote a dissertation on game theory. Forty-five years later he got for this job Nobel Prize on economics. Nash's contribution was described as "for his fundamental analysis of equilibrium in the theory of non-cooperative games."

Neumann and Morgenstern were engaged in so-called zero-sum games, in which the gain of one side is equal to the loss of the other. Between 1950 and 1953, Nash published four, without exaggeration, revolutionary papers in which he provided an in-depth analysis of non-zero-sum games - a class of games in which the sum of winning participants is not equal to the sum of losses of losing participants. An example of such a game would be negotiations on wage increases between the trade union and the management of the company. This situation can end either in a long strike in which both sides suffer, or in reaching a mutually beneficial agreement. Nash saw the new face of competition by simulating what came to be known as the "Nash equilibrium" or "non-cooperative equilibrium" in which both parties use an ideal strategy to create a stable equilibrium. It is beneficial for the players to maintain this balance, since any change will only worsen their position.

In 1951, John Nash began working at the Massachusetts Institute of Technology (MIT) in Cambridge. There he wrote a number of articles on real algebraic geometry and the theory of Riemannian manifolds, which were highly appreciated by his contemporaries. But John's colleagues avoided - his work mathematically substantiated the theory of surplus value of Karl Marx, which was then considered heretical in the USA during the "witch hunt". Outcast John is left even by his girlfriend, nurse Eleanor Steer, who was expecting a child from him. Having become a father, he refused to give his name to the child to be entered on the birth certificate, and also to provide any financial support to his mother in order to protect them from persecution by the McCarthy commission.

Nash has to leave MIT, although he was a professor there until 1959, and he leaves for California to work for the RAND corporation, which is engaged in analytical and strategic development for the US government, which employed leading American scientists. There, again through his research in game theory, Nash became one of the leading cold war. Although the RAND Corporation is known as a haven for dissidents in opposition to Washington, even there John did not get along. In 1954, he was fired after the police arrested him for indecent behavior - changing clothes in the men's room on the beach in Santa Monica.

Disease

Soon John Nash met a student, a Colombian beauty Alicia Lard and in 1957 they got married. In July 1958, Fortune magazine named Nash America's Rising Star in "New Mathematics". Soon Nash's wife became pregnant, but this coincided with Nash's illness - he developed symptoms of schizophrenia. At this time, John was 30 years old, and Alicia - 26. Alicia tried to hide everything that was happening from friends and colleagues, wanting to save Nash's career. The deterioration of her husband's condition depressed Alicia more and more.

In 1959 he lost his job. Over time Nash was involuntarily committed to a private psychiatric clinic in the suburbs of Boston, McLean Hospital, where he was diagnosed with paranoid schizophrenia and subjected to psychopharmacological treatment. Nash's lawyer managed to secure his release from the hospital after 50 days. After being discharged, Nash decided to leave for Europe. Alicia left her newborn son with her mother and followed her husband. Nash tried to obtain political refugee status in France, Switzerland and the GDR and renounce American citizenship.

However, under pressure from the US State Department, these countries denied Nash asylum. In addition, the actions of Nash were monitored by the American naval attaché, who blocked his appeals to embassies. different countries. Finally, the US authorities managed to achieve the return Nash- he was arrested by the French police and deported to the USA. Upon their return, they settled in Princeton, where Alicia found work. But Nash's illness progressed: he was constantly afraid of something, spoke of himself in the third person, wrote meaningless postcards, called former colleagues. They patiently listened to his endless discussions about numerology and the state of political affairs in the world.

In January 1961, a completely depressed Alicia, John's mother, and his sister Martha made the difficult decision of placing John at Trenton State Hospital in New Jersey, where John underwent insulin therapy, a harsh and risky treatment, 5 days a week for two and a half months. After his release, Nash's colleagues from Princeton decided to help him by offering him a job as a researcher, but John again went to Europe, but this time alone. He sent only cryptic letters home. In 1962, after three years of confusion, Alicia divorced John. With the support of her mother, she raised her son by herself. Subsequently, he also developed schizophrenia.

Fellow mathematicians continued to help Nash- they gave him a job at the university and arranged a meeting with a psychiatrist who prescribed antipsychotic medication. Nash's condition improved and he began to spend time with Alicia and his first son, John David. “It was a very encouraging time,” recalls John's sister Martha. - It was quite a long period. But then everything started to change.” John stopped taking his medication, fearing that it might interfere with mental activity, and the symptoms of schizophrenia reappeared.

In 1970, Alicia Nash, being sure that she had made a mistake by betraying her husband, accepted him again, and this may have saved the scientist from a state of homelessness. In later years, Nash continued to go to Princeton, writing strange formulas on blackboards. Princeton students nicknamed him "The Phantom".

Then, in the 1980s, Nash became noticeably better - his symptoms subsided and he became more involved in surrounding life. The disease, to the surprise of the doctors, began to recede. In fact, Nash began to learn to ignore her and took up mathematics again. “Now I think quite rationally, like any scientist,” Nash writes in his autobiography. “I won’t say that it gives me the joy that anyone who recovers from a physical illness experiences. Rational thinking limits man's ideas about his connection with the cosmos.

Confession

On October 11, 1994, at the age of 66, John Nash received the Nobel Prize for his work on game theory.

However, he was deprived of the opportunity to give the traditional Nobel lecture at Stockholm University, as the organizers feared for his condition. Instead, a seminar was organized (with the participation of the laureate) at which his contribution to game theory was discussed. After that, John Nash was still invited to give a lecture at another university - Uppsala. According to Krister Kiselman, professor at the Mathematical Institute of the University of Uppsala, who invited him, the lecture was devoted to cosmology.

In 2001, 38 years after their divorce, John and Alicia remarried. Nash returned to his office at Princeton, where he continues to study mathematics.

In 2008, John Nash gave a talk on "Ideal Money and Asymptotically Ideal Money" at international conference Game Theory and Management in high school management of St. Petersburg State University.

In 2015, John Nash received the highest honor in mathematics, the Abel Prize, for his contributions to the theory of non-linear differential equations.

"Mind games"

In 1998, American journalist (and Columbia University economics professor) Sylvia Nazar wrote a biography of Nash called A Beautiful Mind: The Life of Mathematical Genius and Nobel Laureate John Nash. . The book became an instant bestseller.

In 2001, under the direction of Ron Howard, based on the book, the film A Beautiful Mind was filmed (in the Russian box office - A Beautiful Mind). The film won four Oscars (Best Picture, Best Adapted Screenplay, Director and Supporting Actress), a Golden Globe Award and was awarded several BAFTA awards (British Film Achievement Award).

On October 11, 1994, John Forbes Nash Jr. received the Nobel Prize for his pioneering work on game theory. Nash was 66 years old and suffered from paranoid schizophrenia for most of his adult life.

Nash began his Ph.D. work in 1948 at Princeton, when he was 20 years old. At the age of only 21, he wrote a 27-page doctoral dissertation on game theory, that is, on the mathematics of competition. The great John von Neumann, then at Princeton, was involved in win-lose competition. Now Nash has shown how to construct a mathematical scenario in which both sides win. He found stable scenarios in which neither player would benefit from continued rivalry.

Nash looked at the problem of rivalry with completely different eyes and attracted the attention of theoretical economists. They turned game theory into a tool. Thanks to this young genius, this area of ​​\u200b\u200bknowledge brought new fruits.

He got a job at MIT and for eight years astounded the mathematical world. He also worked within economic theory. He even invented the dice game sold by Parker Brothers. In 1957 he got married. The New York Times correspondent Sylvia Nazar tells how Fortune magazine in July 1958 selected him as the outstanding young star of "new mathematics". Fate smiled on John Nash.
And now, a disaster! He was stricken with mental illness. He began to hear voices. He amazed mathematicians with his incredible conclusions. However, now his results no longer make any sense, although this was not obvious at first glance. He began to look for secret messages in numbers. He disappeared for several days. According to Nazar, he "could no longer sort and interpret sensations or accept rational arguments and was unable to experience the full gamut of emotions."

According to the Freudian psychologists of the 1950s, his wife's pregnancy brought him to the brink. The joys of marital relations brought his illness to the limit. The marriage ended, but his wife took him in, and he lived here on a pension paid to him by Princeton.
For 25 years, John Nash suffered from mental illness. He became a spirit, roaming the halls of Princeton and languishing in his own personal hell. It wasn't until the mid-1980s that Nash finally learned to control this demon and started doing math again.

Meanwhile, game theory has become an essential tool in business and economic theory. All research in this area was based on the famous work of Nash. In the end, Nash won the Nobel Prize in Economics. Usually Nobel laureates have some political support somewhere in the back alleys. However, everything that Nash had was his personal merit.

Today he is working on new possibilities for using the computer. Princeton gave him an appropriate research position. Nash endured what seemed like death. And we can now look at mental illness more compassionately and much more realistically.

In 2015, John Nash received the highest award in mathematics, the Abel Prize, for his contributions to the theory of non-linear differential equations.

Everyone knows the life story of this man mainly thanks to movie "A Beautiful Mind". However, the real genius mathematician John Nash differed in many ways from the character portrayed on screen by Russell Crowe. It was an amazing life for an amazing person.

John Forbes Nash was the most ordinary American teenager who did not demonstrate exceptional success in any school subject, including mathematics. His life was turned upside down by the book The Mathematicians, written by the American popularizer of science Eric Temple Bell, which fell into his hands. This happened in 1942. John Nash was 14 at the time.

Law of balance

Mathematics for quite a long time remained for Nash more of a favorite pastime than a vocation. After school, he entered the Carnegie Polytechnic Institute, where he first studied chemistry, then tried to find himself in the field of international economics. But in the end he decided that numbers, formulas and theorems attracted him the most in the world.

In 1947, he went to continue his education at the legendary Princeton University. In his pocket he had a letter of recommendation from the institute teacher Richard Duffin: “I recommend Mr. John Nash, who applied for admission to Princeton. Mr. Nash is 19 years old and graduated from Carnegie Polytechnic Institute in June. He is a math genius."

At Princeton, Nash met with "game theory" - a mathematical method of searching best strategy. Already in 1949, a 21-year-old student submitted his dissertation to the Academic Council.

The concept of negotiation he formulated in the 1950s (mathematicians call it “Nash equilibrium”) seems to be extremely simple. In short, it boils down to the fact that during negotiations (whether political, economic or domestic) both parties must take into account the interests of each other.

Young John Nash

If negotiators strive to cooperate, and not harm each other, then all participants will ultimately benefit, and the overall effectiveness of negotiations will increase significantly.

It doesn't seem like such a difficult idea. But, being translated by Nash into the language of mathematical formulas, she was able to arrange a real revolution in the world economy. Previously, it was possible to respect the interests of the other side by referring to ethical or moral principles. Now, from a scientific point of view, the “Nash equilibrium” has demonstrated all the inefficiency and harm of wild capitalism, when everyone sought to “drown” a competitor by any means.

The Art of Encryption

In the early 1950s, John Nash was invited to freelance for the RAND Corporation, an organization that worked for the US government and US intelligence agencies on national security issues. What exactly John Nash was working on at this time is still a secret.

But, given that these were the years of the Cold War, most likely, he had to somehow come into contact with the topic of protection from the “red threat”. At the same time, Nash taught at the Massachusetts Institute of Technology.

More recently, it became known that in 1955, John Nash sent several letters to the Agency national security USA.

In them, he described in detail invented by him new approach to cryptography. Simplifying as much as possible, Nash's method boiled down to the fact that the longer the key to the cipher, the more difficult it is to break this cipher.

“The importance of this general hypothesis, assuming its truth, is easily seen,” wrote Nash. - It means that it becomes quite likely to create ciphers that will be virtually unbreakable. As the complexity of the cipher increases, the cipher-breaking game between skillful teams, etc., will become history.”

Cryptography methods like those proposed by Nash did not come into use until the mid-1970s.

So the mathematician was ahead of his time by at least 20 years. But then, in the 1950s, the letters went into the archives of the NSA, were strictly classified and were not actually used.

The fact is that Nash has already managed to gain a scandalous reputation as an eccentric, prone to incomprehensible antics and living in his own strange world. In general, many scientists who are too immersed in science are famous for such features.

But with Nash, it sometimes took on very strange forms. For the same reason, RAND quickly refused to cooperate with him.

Nevertheless, in 1950 until 1959, John Nash's life, one might say, went uphill. In 1957, he married the beautiful Alicia Lard. A year later, the influential Fortune magazine named him "the rising star of the new mathematics." But it soon became clear that his problems were something more than just distraction and eccentricity.

Struggling with schizophrenia

US legislation at that time was not distinguished by excessive liberalism, and therefore the mad scientist was soon placed for compulsory treatment in one of the Boston psychiatric clinics. To get out of there, he had to resort to the help of a lawyer.

Frightened and sick, John Nash left America and rushed around Europe for about a year, trying to get political asylum in several countries. However, the American government could not allow a person to emigrate who, albeit briefly, had access to classified information. Therefore, Nash was arrested in France and returned to the US.

There the disease came upon him. new force. He spoke about himself in the third person, constantly pestered his acquaintances phone calls, during which he confusingly and incoherently talked about numerology, then about international politics, then again about aliens.

In this state, he could neither work nor conduct a normal family life. Followed by new courses of treatment, which did not give any result. As a result, Alicia, with pain in her soul, divorced her insane husband and raised their son alone. It seemed that nothing could save this brilliant mind from complete disintegration.

Luckily Nash was not abandoned by his friends. They even helped him find a job at Princeton. There, Nash received the respectfully fearful nickname Phantom from students. For days on end, he wandered the corridors of the university, muttering something under his breath and periodically scribbling blackboards in classrooms with chains of absolutely incomprehensible formulas.

But over time, the disease began to recede. By the 1980s, Nash had almost completely recovered. His wife returned to him, and hallucinations and obsessions receded.

“Now I think quite rationally, like any scientist,” Nash said of himself. “I won’t say that it gives me the joy that anyone who recovers from a physical illness experiences. Rational thinking limits man's ideas about his connection with the cosmos.

John Nash could forever remain a little-known madman who put forward several
interesting theories, if in 1994 world recognition had not fallen upon him. The Nobel Committee awarded him a prize in economics.

For the very ideas about balance and negotiation tactics that he put forward as a very young man. Due to illness, Nash was unable to give the laureate's traditional lecture in Stockholm. But his authority as a mathematician since that time has become indisputable. The power of the mind turned out to be stronger than the stupefaction of reason.

His amazing fate attracted the attention of Hollywood screenwriters, and in 2001 the film A Beautiful Mind was released with Russell Crowe in the title role. The creators of the picture tactfully circumvented many facts of unfair treatment of the scientist by the American authorities. And instead of hunting for aliens, Nash was credited with spy mania.

The hallucinations, which in reality were only auditory, were portrayed as visual in the film. But, despite all these inaccuracies, the film earned a lot of positive ratings and received four Oscars and a Golden Globe. Nash himself, as far as is known, treated him with restraint and positive.

In 2015, John Nash was awarded the Nobel Prize in Mathematics. The American became the only person in the world to receive both this and the Nobel Prize. Alas, after just a month, the life of a genius was cut short as a result of a banal traffic accident.

Mathematician and Nobel laureate John Forbes Nash Jr. was born on June 14, 1928. John Nash is a mathematician who has worked in the fields of game theory and differential geometry. He shared the 1994 Nobel Prize in Economics with two other game theorists, Reinhard Selten and John Harsanyi.

V scientific world there are rumors that John was awarded the Nobel Prize for just one of his simplest works, and many of Nash's theories are simply beyond my understanding. The most interesting thing is that John Nash did not use the works of his predecessors, he simply created most of his theories about “out of nowhere”, without using ready-made materials and theory. During his studies, John Nash even refused to attend lectures, arguing that he would not learn anything new there, but would just lose precious time.

After a promising start to his mathematical career, John Nash began to develop schizophrenia in his 30s, a disease that the mathematician learned about 25 years later.

John Forbes Nash Jr. was born in Bluefield, West Virginia to John Nash Sr. and Virginia Martin. His father was an electrical engineer, his mother was a teacher. in English. As a teenager, John spent a lot of time reading books and doing various experiments in his room, which soon became a laboratory. At the age of 14, John Nash proved Fermat's Little Theorem on his own.

From June From 1945 to June 1948, John Nash attended Carnegie Polytechnic Institute in Pittsburgh, intending to become an engineer like his father. Instead, John fell deeply in love with mathematics and had a particular interest in topics such as number theory, the Diophantine equations of quantum mechanics, and the theory of relativity. Nash was especially fond of solving problems.

At Carnegie, Nash became interested in the "negotiation problem" that John von Neumann had left unresolved in his book Game Theory and Economic Behavior (1928).

After Pittsburgh, John Nash Jr. went to Princeton University, where he worked on the theory of equilibrium. He received his Ph.D. in 1950 with a thesis on non-cooperative games. The dissertation contained the definition and properties of what would later be called the "Nash Equilibrium", 44 years later, it would win him the Nobel Prize. His research on the subject led to three papers, the first titled "Points of Equilibrium in N-Number Games" published in Proceedings of the National Academy of Sciences (USA) (1950) and the rest in "Econometrics" on the problem of negotiation (April 1950) and "Non-cooperative games with two players" (January 1953) .

Summer 1950 John Nash worked for the RAND Corporation in Santa Monica, California, where he returned for shorter periods in 1952 and 1954. In 1950-1951, Nash taught calculus at Princeton, studied and managed to "slop down" military service. During this time, he proved the Nash theorem on regular embeddings, which is one of the most important in differential geometry on manifolds. From 1951-1952 John became a research assistant at the Massachusetts Institute of Technology in Cambridge, Massachusetts.

At the Massachusetts Institute of Technology, John Nash met Alicia Lard, a student from El Salvador, whom he married in February 1957. Their son John Charles Martin (born May 20, 1959) remained unnamed for a year, as Alicia, since John Nash was in psychiatric clinic, did not want to give a name to the child on her own. Following in his parents' footsteps, John became a mathematician, but like his father, he was diagnosed with paranoid schizophrenia. John Nash had another son, John David (born June 19, 1953) with Eleanor Steer, but he wanted nothing to do with them. Recognized as bisexual, Nash had relationships with men during this period.

Although Alicia and John divorced in 1963, they remarried in 1970. But according to Nash's biography, Sylvia Nazar, they lived "like two distant relatives under the same roof" until John Nash won the Nobel Prize in 1994 , then they resumed their relationship and married on June 1, 2001.

V 1958 John Nash began to show the first signs of his mental illness. He became paranoid and was admitted to McLean Hospital in April-May 1959, where he was diagnosed with paranoid schizophrenia. After a problematic stay in Paris and Geneva, Nash returned to Princeton in 1960. He wandered through psychiatric hospitals until 1970 and did research at Brandeis University from 1965 to 1967. Between 1966 and 1996, John Nash did not publish a single scientific paper. In 1978 he was awarded the John von Neumann Prize for "Equilibrium analysis in the theory of non-cooperative games".

The psychological state of John Nash slowly but gradually improved. His interest in mathematical problems is gradually returning, and with it his ability to logical thinking. In addition, he became interested in programming. 1990s his genius returned. In 1994, John Nash received the Nobel Prize in Economics as a result of his work on game theory at Princeton.

Since 1945 to 1996 Nash published 23 scientific work, plus the autobiography "Les Prix Nobel" (1994) .

A film called A Beautiful Mind starring Russell Crowe, released in December 2001 and directed by Ron Howard, showed some events from the biography of John Nash. It, (tentatively) based on the 1999 biography of the same name by Sylvia Nazar, won 4 Oscars in 2002. However, in this film, many events from John's life are embellished or even untruthful, as is the case in many film adaptations to create a greater effect on the audience. Unlike in the film, Nash's manifestations of schizophrenia did not consist of deciphering newspapers for spies. In fact, it seemed to John that encrypted messages from aliens periodically appeared in the newspapers, which only he could decipher. But all this is nonsense. In the film, John Nash is not cured of schizophrenia, which in turn is incurable. V real life everything is much more interesting. For thirty years, Nash was in various psychological clinics, from which he periodically escaped, but at one point, John was mysteriously cured. How this happened is still a mystery...

Mathematician and Nobel laureate John Nash died in a car accident in the US state of New Jersey at the age of 86. According to a local police spokesman on Sunday, May 24, Nash was in a taxi with his 82-year-old wife Alicia, who also died. According to the police, the driver lost control and crashed into a bump stop. According to preliminary data, both passengers were not wearing seat belts and died on the spot, reports dpa. The taxi driver was injured and was taken to the hospital.
