Greek philosophers said it as “panta rhei”, that is “all things flow”. The flow of a liquid through a bottleneck, the passage of grains (as, e.g., chickpeas) through a hole in a container, the exit of a crowd of people through the door of a room… these are different phenomena from different scientific domains. However, researchers are thinking about a common mathematical description to explain these flow phenomena, encountered in research fields as varied as physics, biology or the human sciences! The potential implications of the success of such an approach would be enormous: from the design of new materials, to the understanding and preservation of ecosystems, to the management of large masses of people in metropolitan environments. The question is: up to what extent do all things flow? Or, in other words, which way?
