Na­ture, our guru

Down to Earth - - LETTERS - A JA­GADEESH NEL­LORE

there is no such thing as waste—any­thing left over from one an­i­mal or plant be­comes food for an­other species. Hu­mans have looked at na­ture for an­swers to prob­lems through­out our ex­is­tence. This science is biomimet­ics. Hu­man en­gi­neers and de­sign­ers have con­tin­ued to look to­wards na­ture for so­lu­tions to mod­ern prob­lems. All mod­ern science that we look at with awe to­day has its ori­gin in biomim­ick­ing. For in­stance, cam­eras (from the eye), air­plane (from birds in flight), radar (from bats), desert cooler (from rab­bit ears), sy­ringe (from snake fangs) and dial­y­sis ma­chine (from kid­neys) are some of the ex­am­ples where mod­ern tech­nol­ogy has been de­rived by mim­ick­ing na­ture. Na­ture, then, is the great­est teacher. I be­lieve the fu­ture will throw up more dis­cov­er­ies and in­ven­tions hav­ing their ori­gins in biomimet­ics.
