What is A Beautiful Mind about?

The unique story of John Forbes Nash Jr. is one of genius, insanity and recovery. The subject of the Oscar-winning film of the same name, A Beautiful Mind (1998) chronicles the remarkable life of a mathematical genius who, at the age of 30, was diagnosed with paranoid schizophrenia and had his world flipped upside down. Three decades later, after a miraculous recovery, he was awarded a Nobel Prize for his work in game theory.

Key idea 1 of 9

Even as a boy, John Forbes Nash Jr. seemed to be a mathematician in the making.

For one of the greatest mathematical minds of the twentieth century, John Nash’s origins were humble enough. He was born in Bluefield, West Virginia, on June 13, 1928. His father, John Sr., was an electrical engineer, and his mother, Margaret, was a schoolteacher.

We don’t know much about his early childhood, but it seems his family was loving and lived a comfortable enough life.

But Nash’s distinctive character soon marked him out. At elementary school, he was extremely socially awkward, always preferring books to people.

In fact, his parents were so worried about his lack of social skills that they enrolled him in socializing activities such as Sunday school and Boy Scouts. These had little effect.

When he was thirteen or fourteen, he began showing early signs of his future mathematical genius. Nash’s passion for mathematics seems to have been ignited by E. T. Bell’s Men of Mathematics, a volume devoted to the lives of great mathematicians.

The early signs of brilliance weren’t what you might expect. He got a B minus in fourth grade math, for instance. But he only got marked down because he wasn’t in the habit of showing his work. This would continue into high school; he’d simply write the answers out or solve the problem in his head using novel, or unorthodox methods.

He didn’t decide to become a mathematician proper until he entered university.

Initially, Nash had had aspirations to become an engineer like his father, so he’d enrolled with a full scholarship to study engineering at Carnegie Institute of Technology (CIT), in Pittsburgh, known today as Carnegie Mellon.

But Nash was bored by lab experiments and mechanical drawing. What he really liked were his mathematics courses.

His math professors were astounded: Nash’s methods for solving difficult mathematical puzzles were startlingly original, and they convinced him to switch majors in his second year.

Nash’s destiny was now fixed.

While a graduate student at Princeton, Nash’s true genius became evident.

Nash found that he could take his pick when it came to grad school. Princeton, Harvard, Chicago and Michigan had all made him offers. Initially, Harvard was his first choice. But Princeton offered him a better scholarship. Nash was swayed and so his nearly six-decade long association with the institution began.

What was special about Princeton was that it provided plenty of academic freedom for its mathematics students to develop intellectually. It was perfect for Nash.

Nash’s doctoral thesis on game theory later established him in the mathematical pantheon.

At Princeton, Nash studied under John von Neumann, the father of modern game theory.

In its essence, the task of game theory is to produce mathematical models of rational human decision-making. Specifically, these decisions take place within games that involve conflict or cooperation, such as poker or chess.

Nash left Princeton and took his mathematical ideas to MIT.

Nash’s thesis was astounding enough for him to earn wide recognition. It wasn’t enough, however, to land him his dream job: a professorship at Princeton. But this was pretty understandable – Nash’s misanthropy and eccentricity hardly made him an ideal candidate for a teaching position.

Nash was able to secure a post at the Massachusetts Institute of Technology (MIT), however. So, in June 1951, he moved to Boston to take up a position as an instructor hopefully on track for tenure.

Nash’s philandering almost cost him his career, but he finally married.

It wasn’t altogether clear what Nash hoped to achieve with his on-again, off-again relationship with Eleanor Stier and his son. Much less ambiguous was the crush that a young physics student, Alicia Larde, had on her professor, John Nash.

At the time, there were few female physics students enrolled at MIT, and, in this environment, it wasn’t uncommon for a young and attractive mathematical genius like Nash to be idolized. Nash finally asked Larde out in the spring of 1955, and they began intermittently dating.

Under immense stress, Nash’s behavior became increasingly erratic and abnormal.

In 1958, nearing 30, Nash found himself becoming increasingly anxious. He was consumed with worry because he hadn’t yet been given tenure at MIT, and also because he’d had no mathematical breakthroughs since his graduate thesis on the equilibrium.

Consequently, Nash decided to take on the Riemann hypothesis, a notoriously difficult unsolved problem related to the distribution of prime numbers.

Just as it seemed Nash’s career was turning a corner, he was diagnosed with schizophrenia.

The timing of Nash’s sudden degeneration of mental health could not have been worse.

He was on the point of being offered tenure at MIT and had even been offered a prestigious professorship at the University of Chicago.

In the 1960s, Nash entered a vicious cycle, followed by two decades of obscurity.

It took almost a year of wandering between American embassies in Europe, but, eventually, Nash was deported back to the United States.

But Nash's condition didn’t improve. Through much of the 1960s, he existed in a vicious cycle. He would be institutionalized, medicated and then seeming to recover, only to relapse and head once more to Europe.

Nash's seemingly unbelievable recovery was accompanied by even more rewards.

All seemed lost. But, miraculously, Nash began to recover from his illness.

It happened in stages, and it’s impossible to pinpoint exactly when the paranoid schizophrenia began to subside. It certainly took several years for others to notice that Nash was improving.
