Who Was John Nash?
John Forbes Nash, Jr. was an American mathematician who made significant contributions to various fields, including game theory, real algebraic geometry, differential geometry, and partial differential equations. Born on June 13, 1928, Nash became renowned for his groundbreaking work and received numerous prestigious awards.
During his time as a graduate student in the Department of Mathematics at Princeton University, Nash introduced several fundamental concepts that are now considered central to game theory, such as Nash equilibrium and the Nash bargaining solution. These concepts have found applications in various scientific disciplines. Nash's work had a profound impact on the field of game theory and earned him recognition, including the Nobel Memorial Prize in Economics in 1994, which he shared with fellow game theorists John Harsanyi and Reinhard Selten. In 2015, he was also honored with the Abel Prize, along with Louis Nirenberg, for their contributions to the field of partial differential equations.
One of Nash's notable achievements during his graduate studies was his discovery and proof of the Nash embedding theorems. He successfully solved a system of nonlinear partial differential equations that had implications in Riemannian geometry. This work also involved a preliminary version of the Nash–Moser theorem. The American Mathematical Society recognized the importance of Nash's contributions by awarding him the Leroy P. Steele Prize for Seminal Contribution to Research. Additionally, Nash, along with Ennio De Giorgi, made significant strides in understanding elliptic and parabolic partial differential equations through their separate methods. Their collaborative result, known as the De Giorgi–Nash theorem, resolved a well-known open problem called Hilbert's nineteenth problem on regularity in the calculus of variations. This problem had remained unsolved for almost sixty years.
Unfortunately, in 1959, Nash began experiencing symptoms of mental illness, ultimately diagnosed as schizophrenia. He spent several years in psychiatric hospitals undergoing treatment for his condition. However, after 1970, Nash's mental health gradually improved, allowing him to resume his academic pursuits by the mid-1980s.
Nash's life story and his struggles with mental illness were chronicled in Sylvia Nasar's 1998 book, "A Beautiful Mind." The book brought attention to Nash's remarkable recovery and resilience. It later served as the basis for a film adaptation of the same name, directed by Ron Howard. In the film, Russell Crowe portrayed Nash, bringing his story to a wider audience.
John Nash's contributions to mathematics and his resilience in the face of mental illness continue to inspire and influence generations of mathematicians and researchers. His groundbreaking work in game theory and partial differential equations remains highly regarded in the scientific community.
What Did John Nash Discover?
Although John Nash did not publish extensively, his papers are highly regarded as landmarks in various fields. During his time as a graduate student at Princeton University, he made significant contributions to game theory and real algebraic geometry. Nash's foundational work on non-cooperative games and the definition of Nash equilibrium, which are crucial concepts in game theory, formed the basis of his PhD dissertation. This work, supervised by Albert W. Tucker, earned him his doctorate in 1950. His thesis was later published in the Annals of Mathematics.
In the realm of real algebraic geometry, Nash made a notable discovery in 1949. He presented his theorem, although without the complete proof, at the International Congress of Mathematicians in 1950. By October 1951, Nash had finalized his theorem and submitted it to the Annals of Mathematics. The theorem addressed the relationship between closed smooth manifolds and smooth functions on Euclidean space. Nash demonstrated that these functions could be represented as polynomials, which was a surprising and significant result. His proof introduced the concepts now known as Nash function and Nash manifold, which have since become the subject of extensive study in real algebraic geometry. Notably, Nash's theorem found applications in the study of dynamical systems, thanks to the work of Michael Artin and Barry Mazur, who combined Nash's polynomial approximation with Bézout's theorem.
In addition to his contributions to game theory and real algebraic geometry, Nash's interests expanded to the field of differential geometry during his postdoctoral fellowship at MIT. While his work in differential geometry was expressed in a geometric language, it primarily focused on the mathematical analysis of partial differential equations. Nash made significant progress in this area, proving the De Giorgi–Nash theorem, which resolved a form of Hilbert's nineteenth problem related to the smoothness of solutions to certain equations.
Apart from his mathematical achievements, in 2011, previously classified letters written by Nash in the 1950s were declassified by the National Security Agency. These letters revealed Nash's proposals for a new encryption-decryption machine, indicating his anticipation of concepts that would become fundamental in modern cryptography, based on computational hardness.
Overall, John Nash's contributions to mathematics spanned various fields, and his theorems and concepts continue to have a significant impact in their respective areas of study.
John Nash Interview
John Nash Wife
John Nash had two wives in his lifetime. His first wife was Eleanor Stier, whom he met while admitted as a patient and had a relationship with in the early 1950s. They had a son named John David Stier together. However, Nash left Stier after learning of her pregnancy. This aspect of Nash's personal life, including his relationship with Stier, was not portrayed in the film "A Beautiful Mind," which received criticism for omitting this part of his story.
Nash's second wife was Alicia Lardé Lopez-Harrison. They met not long after his separation from Stier. Alicia, a naturalized U.S. citizen from El Salvador, had studied physics and graduated from MIT. Nash and Alicia got married in February 1957, and their wedding ceremony took place in an Episcopal church, despite Nash being an atheist. They had a son named John Charles Martin Nash a few months after Nash resigned from his position at MIT in 1959.
The relationship between John Nash and Alicia faced significant challenges due to Nash's battle with mental illness. The stress of dealing with Nash's illness eventually led to their divorce in 1963. After his final hospital discharge in 1970, Nash moved back to Alicia's house and lived there as a boarder. This living arrangement seemed to provide stability for Nash and positively impacted his well-being. He learned to consciously reject his paranoid delusions during this time.
Nash and Alicia remained connected, and their relationship deepened in the 1990s. They remarried in 2001, showing a renewed commitment to one another. Their son, John Charles Martin Nash, went on to earn a PhD in mathematics from Rutgers University but later received a diagnosis of schizophrenia as an adult. Throughout the ups and downs of their relationship, Alicia played a significant role in supporting Nash and caring for him during his struggles with mental illness.
