It is indeed a rare occasion when a mathematician is the subject of a popular, award winning movie. John Nash was the subject of the recent hit movie, "A Beautiful Mind." However, that is almost totally due to the human interest aspects of his battle with paranoid schizophrenia rather than his mathematics. The focus of this book is on his advances in mathematics, done by reproducing his early papers.
Like so many excellent mathematicians, Nash also did some work in recreational mathematics, and he independently invented the game now known as Hex. Played on a board of hexagonal sections, the object is to create a continuous chain of your color from one side to the other. A short chapter explains the basis of the game, although it does not do justice to the complexity .
Nash's work in game theory is outstanding, and the reason why he won the Nobel prize in economics. The bulk of the book is a recreation of his seminal work in this area, with his Ph. D. thesis being presented twice. The first is a photocopy of the work and the second is the thesis in text form. In reading the material, it is easy to see why it has applications in so many areas.
Nash was also interested in computing and he wrote an imaginative paper on parallel computing, which is included in the book. Given the state of computing at the time it was written, it shows imagination and fundamental understanding of the basics of computing.
The last two papers in the book deal with manifolds. The first concerns real algebraic manifolds and the second examines abstract Riemannian manifolds. Once again, you can see aspects of genius in the papers and avenues for further exploration.
It is a mathematical tragedy that John Nash was almost totally unable to work for so many years. In fact, when it was announced that he had won the Nobel prize, many were surprised to hear that he was still alive. In reading these papers from the early years of his career, it is clear to see that had he not became ill, he would have had a shot at being labeled the best mathematician of the century. Long after memories of the movie have faded away, Nash's work will still be applied to the problems of the world.
