The problem of describing the evolution, stability and equilibrium shapes of a fluid droplet immersed in another viscous fluid and subject to different forces has provided the scientific community, for more than three centuries, with an endless source of inspiration and challenges. The origin of this area of study dates back to the theories of Isaac Newton that explain the Earths shape as a self-gravitating mass of fluid rotating in space, and the experiments designed by the belgian physicist Plateau between 1843 and 1869 to validate Newtons work. Over the last decades, models for...
