penguins!
fuckyeahfluiddynamics:
Penguins, already fluid dynamicists by nature, have developed clever methods of increasing their speed to escape from the leopard seals that prey on them. In the clip above, notice from 1:55 onward as the penguins swim for the surface and leap onto the ice - they leave a trail of bubbles in their wake. The penguins are using supercavitation to decrease their drag. When the penguins first dive in to the water, they splay their feathers out in the air and then lock them closed in the water, trapping pockets of air beneath them. When the need for a burst of speed arises, the penguin shifts its feathers to release the air, coating most of its body in a layer of bubbles. Because the drag in air is much less than the drag in water, this enables the bird to achieve much higher speeds than they normally do when swimming.

UC Berkeley Police attack peaceful student protesters. #occupycal
—The Story of Broke, is a response to the bogus forced austerity programs that the US and many other governments are forcing on our communities. We are being told that we can’t afford clean energy, and that environmental protection is too expensive because we’re broke. But we’re not broke! There is plenty of money to start building a better future, but that money is being hijacked.

Occupy Worcester (MA) Occupies a Home Foreclosure Auction
Just before 11 am today- November 8, 2011, members of the Worcester Anti-Foreclosure Team (WAFT), homeowners Pablo and Shirley Travieso and family, and members of Occupy Worcester lined up in front of the Traviesos’ two-story house at 24 Illinois St. — where the family has lived for 10 years — and drowned out the voice of auctioneer John Baker by chanting loudly, and blocked his entry to the property.
