The power of mathematics as a language of science lies in the fact that it allows us to describe apparently different phenomena by means of a common pattern. In this lecture I explain the relationships between voting systems in the Council of Ministers of the European Union and the Brownian Motion. We show why some quantities (the voting power of a country in the 'fair' voting system, the mean distance of a diffusing particle from the origin) depend on others (population, time) as the square root.
