Intermittency is a physical phenomenon for which there is still no precise mathematical definition and which appears in different fields, particularly in the field of fluid turbulence. It is therefore relevant to find good examples that mathematically can be understood in detail. In the talk I will present several of these examples that have in common the so-called Talbot effect. Intermittency is in all of them a consequence of how irrational numbers are approximated by rational ones.
