A dance of particles and smoke

Abstract

As we move through the world, we are surrounded by an invisible dance: particles of air and matter silently in motion around us, their choreography dictated by rules of the universe, diffusion, and fluid dynamics. It may seem like we are overcomplicating and romanticising this process in equal measure, but understanding how this matter moves through our environment is an immensely complicated and important process for us to understand. From aerodynamics to public health, understanding how air and matter move through the world does matter to us, because it affects the behaviour of flying aircraft and the spread of airborne pollutants, just to give a few examples!
