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!
"The mahi-mahi or common dolphinfish (Coryphaena hippurus) is a surface-dwelling ray-finned fish found in off-shore temperate, tropical and subtropical waters worldwide. Also known widely as dorado, it is one of two members of the Coryphaenidae family, the other being the pompano dolphinfish.
The name mahi-mahi means very strong in Hawaiian. In other languages the fish is known as dorade coryphène, lampuga, llampuga, lampuka, lampuki, rakingo, calitos, or maverikos." - Mr. Wkipedia
The blacktip shark was first described by Valenciennes in Muller & Henle (1839) as Carcharias (Prionodon) limbatus. It has also appeared in the literature as Carcharias (Prionodon) pleurotaenia, Carcharias microps, Carcharias (Prionodon)muelleri, Carcharias maculipinna, Carcharias ehrenbergi, Carcharias aethlorus, Gymnorrhinus abbreviatus, Carcharias phorcys, and Carcharhinus natator. The currently valid scientific name is Carcharhinus limbatus (Müller and Henle 1839). The genus name Carcharhinus is derived from the Greek "karcharos" = sharpen and "rhinos" = nose. The species name "limbatus" originates from Latin, meaning bordered in reference to the black markings on its fins.
The blacktip shark gets its name from its distinctive black markings on the tips of its fins. It is also known as blackfin (Guam, Micronesia, Trinidad and Tobago), black-tipped (Papua New Guinea), small blacktip (Cuba, Leeward Islands), and spot-fin ground shark (UK).
Blacktip sharks are cosmopolitan in tropical to subtropical coastal, shelf, and island waters. In the Atlantic during their seasonal migration they range from Nova Scotia to Brazil, but their center of abundance is in the Gulf of Mexico and Caribbean Sea. They occur throughout the Mediterranean and along the central West coast of Africa. In the Pacific they range from Southern California to Peru, including the Sea of Cortez. They occur at the Galapagos Islands, Hawaii, Tahiti, and other South Pacific Islands, to the North coast of Australia. In the Indian Ocean they range from South Africa and Madagascar up to the Red Sea, Persian Gulf, throughout India's coast, and east to the coast of China.
I know it's a stretch, but let's try and class up this two bit joint with some art. (that doesn't mean dogs playing cards or shooting pool) Mind you, the painting above reminds me of some benders I've had.
