I love going to the movies, even though it is no easy matter these days to find at the local multiplex thoughtful compositions that engage the Christian mind.

John Nash, as millions of people now know, was a brilliant graduate student at Princeton back in the 1940s, when, among other accomplishments, he invented an analytical tool now known as the "Nash equilibrium." This discovery, for which Nash received the Nobel Prize in 1994, turned out to be one of the foundations of modern game theory, with application to everything from arms control talks to pricing goods in a competitive market.
It is also consonant with profoundly Christian ideals.
Here's why: the Nash equilibrium posits that there are circumstances in which we are better off if we settle for something other than that which we most desire. This may be counterintuitive, but the mathematical proof (which is available for a general audience in William Poundstone's excellent book, Prisoner's Dilemma) is quite elegant.
