This learn node is centered in the 2008 discovery at Rensselaer Polytechnic Institute of how the dolphin kicks with huge power — something that has been a mystery called Gray’s Paradox. Six nodes emerge from the open internet in this animation, providing connected places to learn about dolphins and their power kick.

The center node takes you to the work of Timothy Wei, professor and acting dean of Rensselaer’s School of Engineering, to see how he has solved Gray’s Paradox using his new state-of-the-art water flow diagnostic technology — Digital Particle Image Velocimetry DPIV — that measures the force a dolphin generates with its tail. Other nodes are about DPIV, how the US Navy trains dolphins (a retired Navy dolphin stars in the Rensselear video), general dolphin information (from the San Diego Zoo), and open courseware from Tufts University School of Veterinary Medicine on marine mammal medicine including care of dolphins, who are cetaceans.
