Physicists discover simple propulsion mechanism for bodies in dense fluids

A team of researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), the University of Liège and the Helmholtz Institute Erlangen-Nürnberg for Renewable Energy have developed a microswimmer that appears to defy the laws of fluid dynamics: their model, consisting of two beads that are connected by a linear spring, is propelled by completely symmetrical oscillations. The Scallop theorem…
