I love movies about great mathematicians, real or fictional. The Imitation Game and Good Will Hunting are great ones, but A Beautiful Mind is my favorite. This movie profiles John Nash, who became a pioneer in game theory and won a Nobel Prize along the way. Because of this, I paid quite a bit of attention to game theory in grad school and constantly looked for applications. Over time I became disappointed, as the models I experimented with didn’t work as well in the real world as in the “games.”
