This might be handy, if you happen to be dressed up as a ghost or flying superhero or bat, etc - the SCQ has a piece up today, that goes over the physics of learning to fly, a la Hitchhiker's Guide to the Galaxy. In other words, the piece takes a look at some of the Newtonian physics needed to "throw yourself at the ground and miss."
It's quite well done, because it goes through the premise a single concept at a time (the above image for instance noting how to do it to fly for 1 second, and noting the caveat that since you accelerate as you fall, you need some more thinking to work out how to fly "indefinitely."
Anyway, worth a look.
As well, note that today is the last day to submit a question for Bill Hick, the Science Prick, and possibly win a great children's book (we've only received about 15 questions, but odds are good).

This might be eligible for funding in the alternative fuels arena. Would certainly cut down on carbon emmissions. (I'm thinking of giant catapults...)
Well if you're into giant catapults...
