The talk will be about the law of large numbers, in its various manifestations. This is a real cornerstone of probability and, in English, it says that a random system of a very large size is typically not random: its deterministic state is the one that has the largest probability to occur. Maximizing the probability to occur is a variational problem that can be analyzed and sometimes solved. As for any variational problem, there is always something special about the solution, which translates into special and beautiful forms created by pure luck of the draw.
