What an Idea. And look what happened to the Infant mortality rate as a side effect.

Didn't know one could use horses to launch a sailplane. Makes sense, though, just never thought of doing it. I always dreamed of a bike that could fly and pedal around to wherever I wanted to when I was a kid. I guess that's slightly more feasible than wanting to be a dinosaur...nahhh http://framework.latimes.com/2013/05/21 ... sailplane/
I don't have to do anything. I just liked the pictures. And the 2007 APOD also says that the picture was taken as the plane was breaking the sound barrier.

Allegedly.

Real life heroes save little girl falling from window in China:
Aquaporins. Proteins in your cell membranes which facilitate rapid diffusion of water molecules through the membranes they're embedded in. http://www.ks.uiuc.edu/Research/aquaporins/
This is killing me, though. They supposedly let three billion water molecules through per second, which pretty much blows my mind into the same quasi-functional state it goes into when I try to read about quantum mechanics. Even though I believe it as a fact without seeing it happen I don't totally believe it because it seems impossible. I decided to try to calculate (note: I suck at this. I don't trust that the following is totally correct.) how fast the water molecules would have to be traveling in order to achieve that volume. Supposing the protein channel is 3 nm long, each molecule would have to move .9 m/s which is a far cry from the astronomically high velocity I was imagining. Hmm.

Well, to something the size of a water molecule, it may just be an astronomical speed, IF it could understand astronomical.
I suck worse than you at scientific calculations. But .9m/s is about 3-inches per second. For something as small as a water molecule to travel about 3-inches a second, would seem to me, comparatively speaking, to be an astronomical speed. But i could be all wet about it.
