The math of shark skin

The rough surface of shark skin helps sharks move faster through the water. Mathematicians have developed an equation for how this roughness translates into less viscosity for a swimming shark. Emory University math professor Alessandro Veneziani has applied this knowledge to everything from swimsuit design to the study of human blood flowing through arteries to help doctors devise the best strategies for treating aneurisms.
