So we've heard about how fluids can have different viscosities and Newtonian fluids have constant viscosities, where as non-Newtonian fluids have viscosities that change depending on the shear rate or speed with which the object lives through them. Okay, that makes sense.......Go Fish!
Apparently in the future we are going to have micro robots swimming around inside of us with the mission to rid us of bad things. One application discussed is the repair of our eyes. The micro-scallops will gleefully swim in our eye fluid and zap any distortions that they find on the eyeball. Take that Cataract!
We have travelled a long way since scracthing fleas from our hairy bodies on those hot summer nights around the camp fire on the African veldt. Kumbaya!
