JOHN C. HARSANYI (1920-) John C. HARSANYI is an American because he and two other mathematicians made pioneering work in the equilibrium analysis theory of non-cooperative games.

His contribution has had a significant impact on game theory and economics, and he won the Nobel Prize in Economics.

Introduction to John Forbes Nash John Forbes Nash Jr. (June 13, 1928 -), also translated as John Nash, is an American mathematician and former teaching assistant at the Massachusetts Institute of Technology. He mainly studies game theory and

Differential geometry.

In 1994, he and two other game theorists, John C. Harsanyi and Reinhard Selten***, won the Nobel Prize in Economic Sciences.

In 1950, Nash received a doctorate from the Institute for Advanced Study in Princeton, USA. In his doctoral thesis of only 27 pages, he proposed an important concept, which was later called the game theory of "Nash Equilibrium".

The Lonely Genius John Nash was born in 1928 to a wealthy family in Bluefield, an industrial city in West Virginia, USA.

His father was a well-educated electrical engineer and his mother was a Latin teacher.

Nash has been very withdrawn since he was a child. He would rather hide in a pile of books than go out and play with children of the same age.

But at that time, Nash's math scores were not good. Elementary school teachers often complained to his parents that Nash had problems with math because he often used some strange problem-solving methods.

In middle school, this situation became more frequent. According to Reinhard Selten, the teacher calculated the entire blackboard exercise on the blackboard, and Nash was able to solve the answer in just a few simple steps.

After graduating from high school, John Nash entered the chemical engineering department of Carnegie Institute of Technology in Pittsburgh.

In 1948, Nash, who was in his third year of college, was admitted to Harvard University, Princeton University, the University of Chicago and the University of Michigan at the same time. Princeton University was more enthusiastic. When Lefshetz, the chairman of the mathematics department of Princeton University, felt Nash's hesitation

, immediately wrote a letter urging him to choose Princeton, which prompted Nash to accept a scholarship of $1,150.

At that time, Princeton had become the center of mathematics in the world, and world-class masters such as Einstein gathered here.

In Princeton's free academic atmosphere, Nash was at home like a duck in water. He graduated with a doctorate at the age of 21 and was already famous before he was 30.

In 1958, Nash was named the most outstanding figure among the new generation of genius mathematicians by Fortune magazine for his outstanding work in the field of mathematics.

John Nah's most important theory is the "Nash equilibrium" that now appears widely in economics textbooks.

One of the most famous examples of "Nash Equilibrium" is the "Prisoner's Dilemma". The general idea is: two suspects in a case are interrogated separately. The police officer tells the two prisoners separately that if neither of them confesses, they will each be sentenced to one year in prison; if

If you confess but the other party does not, you will be sentenced to three months in prison and the other party will be sentenced to ten years in prison; if both confess, they will both be sentenced to five years in prison.

As a result, the two of them were caught in the dilemma of confessing or not confessing.

The choice for the two prisoners that is in their own interests is to confess. The originally beneficial strategy for both parties would not be possible if they did not confess and both were sentenced to one year in prison.

In this way, both of them chose the confession strategy and were sentenced to 5 years. This is called a "Nash equilibrium", also called a non-cooperative equilibrium.

"Nash Equilibrium" was his doctoral thesis at the age of 21, and it also laid the foundation for him to win the Nobel Prize in Economics decades later.

At that time, Nash was "as handsome as a god", 1.85 meters tall, weighing nearly 77 kilograms, with slender and elegant fingers, soft and beautiful hands, and the appearance of a British aristocrat.

His talent and charisma attracted a beautiful girl, Alicia, one of only two girls in the physics department of MIT at the time.

In 1957, they got married.

The long years that followed proved that this may be the most important thing in Nash's life than winning the Nobel Prize.

Just when he was enjoying success in career and love, Nash was also known as a "lonely genius" because he liked to be alone and solve torturous mathematical problems.

He is not a person who is good at dealing with others and is popular with most people. He has the pride and self-centeredness that geniuses often have.
