John Forbes Nash Jr. was a renowned mathematician and economist who made significant contributions to the fields of game theory, differential geometry, and partial differential equations. Born on June 13, 1928, in Bluefield, West Virginia, Nash exhibited an early aptitude for mathematics and pursued his interests at Carnegie Mellon University and then at Princeton University, where he received his Ph.D. in 1950.

Throughout his career, Nash made numerous contributions to the field of mathematics and economics, including the development of the Nash equilibrium, a concept that has become fundamental to the study of game theory. The Nash equilibrium is a solution concept in which no player can gain an advantage by changing their own strategy, given the strategies of the other players. This concept has been applied to a wide range of fields, including economics, politics, and even biology.

Nash was also known for his work on differential geometry, which is the study of the properties of curves and surfaces in space. In the 1950s, he published several papers on the subject, including one that introduced the concept of isometric embedding, which has become an important tool in the study of manifolds.

In addition to his contributions to mathematics and economics, Nash was also known for his struggles with mental illness. He was diagnosed with paranoid schizophrenia in the late 1950s and spent much of the following decades in and out of hospitals and treatment programs. Despite his struggles, Nash continued to make important contributions to the fields of mathematics and economics, and in 1994, he was awarded the Nobel Prize in Economics for his work on game theory.

Nash passed away in 2015 at the age of 86 in a car accident, but his contributions to mathematics and economics continue to be recognized and celebrated. His life and struggles with mental illness were also the subject of the 2001 film "A Beautiful Mind," which starred Russell Crowe as Nash.

In conclusion, John Forbes Nash Jr. was a brilliant mathematician and economist whose contributions to the fields of game theory, differential geometry, and partial differential equations have had a lasting impact. Despite his struggles with mental illness, Nash persevered and made significant contributions to the field of economics, ultimately being recognized with the Nobel Prize. His legacy as a mathematician and economist will continue to be remembered and celebrated for years to come.

## Biography of John Forbes Nash Jr.

Of course, this sort of thing is in a way what is not supposed to happen. Due to Nash was solving classical mathematical problems, difficult problems, something that nobody else was able to do, not even to imagine how to do it. After the Nobel, Nash received numerous awards in recognition of work that he had done more than 40 years ago. One of Nash's students at MIT, Alicia Larde, became friendly with him and by the summer of 1955 they were seeing each other regularly. They had a son, John David Stier, but Nash left Stier when she told him of her pregnancy. Archived from PDF on April 20, 2015.
