Some of the physical phenomena that we encounter in our daily lives are still not fully understood. A prime example is turbulence in fluids. The complexity of turbulence, which is described by the Navier-Stokes equations governing fluid dynamics, is one of the problems of the millennium. Another example of an open problem is the approach to thermodynamic equilibrium in isolated systems. A new collaborative study between SISSA and the University of Padua, published in Physical Review Letters, analyses in detail a previously unknown link between these two types of phenomena and could open up new avenues for understanding them.
