I remember watching a hammerhead swimming around a work boat from up on an oil rig in the Gulf of Mexico. What struck me the most was not how it swam through the water, but how it cut through the water. A couple hundred million years of evolution has made a very efficient eating machine.
Nothing in the world is more yielding and gentle than water. Yet it has no equal for conquering the resistant and tough. The flexible can overcome the unbending; the soft can overcome the hard. - Lao Tse
