Big Picture Science

March 20

Whether they swim, slither, jump, or fly, animal locomotion is more than just an urge to roam: it’s necessary for survival.  Evolution has come up with ingenious schemes to get from here to there.  Hear how backbones evolved as a consequence of fish needing to wag their fins, and why no animals have wheels. 

Motion is more than locomotion. Test the physics of movement in your kitchen and find out what popping corn has in common with the first steam engine.
