One of the greatest minds of the 20th C. and the subject of the Oscar winning film A Beautiful Mind. http://www.bbc.com/news/world-us-canada-32865248 Beautiful Mind' mathematician John Nash killed in crash US mathematician John Nash, who inspired the Oscar-winning film A Beautiful Mind, has died in a car crash with his wife, police have said. Nash, 86, and his 82-year-old wife Alicia were killed when their taxi crashed in New Jersey, they said. The mathematician is renowned for his work in game theory, winning the Nobel Prize for Economics in 1994. His breakthroughs in maths - and his struggles with schizophrenia - were the focus of the 2001 film. Russell Crowe, who played him in the film, tweeted: "Stunned... My heart goes out to John & Alicia & family. An amazing partnership. Beautiful minds, beautiful hearts." Alicia Nash helped care for her husband, and the two later became prominent mental health advocates. The two were thrown from their vehicle, police said. Media reports said the couple may not have been wearing seatbelts when they crashed. Their taxi driver, and a passenger in another car, were also injured. Nash married Alicia Larde in 1957, when he was a rising star in the maths world. But he developed severe schizophrenia soon after, and Alicia had him committed several times. The couple divorced in 1962. They stayed close, and his condition had begun to improve by the 1980s. They remarried in 2001. Earlier this week, Nash received the Abel Prize, another top honour in the field of mathematics. What is game theory? If you have ever tried to haggle over a price, you may have unknowingly engaged in some of the logic employed in game theory. The subject can be described as the mathematical study of decision-making, conflict and strategy in social situations. The "game" is an attempt to model the decision-making process, those making the choices and what those outcomes might be. It has huge applications, with everything from dating sites to auctions of sports rights using its ideas. The Nash Equilibrium, for which John Nash won his Nobel Prize, describes situations where it is of no benefit for players in a complex game to change strategy, when they consider others'. It helps explain evolutionary stability, for example.
My wife, along with Nash, hails from Bluefield, WV. There's a stretch of highway up there named for him which we used to travel on our visits. That was a great movie and an inspiring love story.
