Part three - Natasha.

This is the biography of John Nash, a brilliant mathematician who at age thirty (before having a chance to realise his potential or even become a full professor) slipped into madness, complete with hearing voices, believing to receive messages from extraterrestrials, alternating between trying to establish a secret world government and trying to hide from it. The illness effectively ended his promising academic career, which started with an article about game theory (that earned him a Nobel Prize in Economics forty years later) and publications on difficult problems that no one else even knew how to start solving. The book, which details not only Nash's life but also the background of various other people and organisations he is involved with (Albert Einstein, John von Neumann, many mathematicians, various universities, and the RAND institute) has recently been turned into a major motion picture and as always in this case I am planning to get the DVD to see how the adaptation went.
