Summary
In nature, some animals perform faster movements than the muscle contraction speed for their survival. Jumping of flea and locusts, shooting cavitation bubbles of snapping shrimps, biting or jumping of trap-jaw ants, and punching of mantis shrimps have attracted not only biologists, but also physicists and engineers. All of them are arthropods, and they utilize ‘exoskeletal springs’ to realize ballistic, extremely fast movements. Arthropods have relatively small brains—micro brains—in comparison with large brains of vertebrates including humans. Mantis shrimp’s strike is used for breaking open the shells of animals such as snails and other arthropods to eat them. I will give you a thought on how mantis shrimp are using ‘intelligently’ the nervous and exoskeletal spring system based on shishi-odoshi model—a mechanical thought model.
Before this seminar, Asli Colpan-san (2nd batch) will give a brief talk on her recent book project – Business Groups in the West.
