Abstract:
In 1908, Poincare’ asked: ”Why is it that storms seem to arise by chance, so that many people find it quite natural to pray for rain or good weather, while they consider it ridiculous to pray for an eclipse?” In other words, why are some physical systems very predictable and others very unpredictable? A hundred years later, we understand, to some extent, the answer to this question. I will give some historical background and describe some simple mathematical models that help us understand the nature and relationship between the concepts of determinism and randomness.
