Physics meets biology in art in this animated video from TED-Ed, in which physicist Aatish Bhatia explains how the world of a sperm is so fundamentally different from the world of sperm whale. He describes a big idea from fluid mechanics called the Reynolds number, and explains why size matters a LOT for a spermy swimmer.
