Test decodes dolphins’ math skills

Nonlinear mathematics may be behind the mammals’ ability to see through bubbles

Dolphins could teach humans a thing or two about finding Nemo. The aquatic mammals may pinpoint prey hidden in bubbles by using mental math.

By adjusting the volume of sonar clicks, then processing the incoming echoes, dolphins might have solved a problem that still stymies man-made sonar: how to peer through frothy water.
