He's making a, kind of, cheek flapping sound.

My talk is Flapping Birds and Space Telescopes.

What does that mean for the origin of flapping flight?

And this is you can see this is a flapping bird.

And here he is, flapping with his ears and very gracefully going up.

They fly, not with rotating components, so they fly only by flapping their wings.

Most people think they know what origami is. It's this flapping birds, toys, cootie catchers, that sort of thing.

This issue continues to hinge on the training of some 600 security auxiliaries drawn from within the ranks of the FN.

We're working on projects now even wing flapping things the size of hawk moths DARPA contracts, working with Caltech, UCLA.

She stopped about 10 feet away from me, and she sat there with this penguin, the penguin's flapping, and she let's it go.

The technical questions are complex, and the proverbial devil really is in the countless details. But prospects for a deal will hinge on resolving three broad issues.

Attainment of the MDGs would largely hinge on how the productive sector was harnessed to enable it to generate the resources necessary to achieve the goals in question.

It is generally believed and there is a modicum of truth in it that success in nuclear disarmament does not hinge on technical issues, but is a matter of political will.

Did they not see the birds above them, stretching out, and flapping their wings. No one keeps them up in the sky except the Beneficent God. He certainly watches over all things.

The one final bit of sparkle we'll put in at the very end here is an utterly impractical flight vehicle, which is a little ornithopter wing flapping device that rubber band powered that we'll show you.

So we looked at the birds, and we tried to make a model that is powerful, ultralight, and it must have excellent aerodynamic qualities that would fly by its own and only by flapping its wings.

The EU must make it clear that it is ready to support Serbia and the region as a whole in realizing its European aspirations. European security is hinged on Serbian integration, just as Serbian aspirations hinge on the EU.

We have a long way to go, probably in a climate that will not turn favorable to immigration for many years. How much progress we can make will hinge on our ability to break through the myths about migration.

But, while the French election s outcome will hinge to a crucial extent on European crisis politics, Germany s government acts as if this were none of its concern. Instead, the main almost exclusive topic in Berlin is the upcoming election.

There are some larger regional consequences in all of this. The Association of Southeast Asian Nations (ASEAN) has tenaciously fought for its place as the geopolitical hinge between East and South Asia, and an important player in Asia Pacific economic and security diplomacy.

If the Round is to be completed by 2006, which is widely recognized as the only narrow window available, further progress will now hinge on the outcome of the 6th WTO Ministerial Conference, to be held in Hong Kong, China, in December 2005.

The possible existence of the organization's responsibility appears to hinge on whether the organization's binding decision actually requires the wrongful act to be done, or whether the act is just one of the ways that a member State may select when implementing the decision.

That said, the economic outlook can never be fully analyzed with conventional statistical models, for it may hinge on something that such models do not include our finding some way to replace one narrative currently a tale of out of control debt with a more inspiring story.

Plenty of robots can fly but none can fly like a real bird. That is, until Markus Fischer and his team at Festo built SmartBird, a large, lightweight robot, modeled on a seagull, that flies by flapping its wings. A soaring demo fresh from TEDGlobal 2011.

Lack of stimulation often leads to self stimulating behaviors like hand flapping, rocking back and forth, or aggression, and in some institutions, psychiatric drugs are used to control the behavior of these children, whilst in others, children are tied up to prevent them from harming themselves or others.

An insect's ability to fly is perhaps one of the greatest feats of evolution. Michael Dickinson looks at how a common housefly takes flight with such delicate wings, thanks to a clever flapping motion and flight muscles that are both powerful and nimble. But the secret ingredient the incredible fly brain.

Unless emerging market governments take advantage of the limited space provided by their foreign exchange reserves and floating currencies to enact vital structural reforms, the onus of adjustment will fall on interest rates, compounding the effects of slowing growth and the risks associated with bad debt. Whether this becomes a systemic issue affecting the entire global economy will hinge on China.

But attached to the base of the wing is a set of little, tiny control muscles that are not very powerful at all, but they're very fast, and they're able to reconfigure the hinge of the wing on a stroke by stroke basis, and this is what enables the fly to change its wing and generate the changes in aerodynamic forces which change its flight trajectory.

Another time, when our path took us by a tranquil stream, I saw a man sitting and watching his line, seemingly at peace with the world, while next to him, fish he had already caught were flapping helplessly and gasping in the air. My father told me that he could not understand how anyone could enjoy an afternoon spent taking fish out of the water and letting them die slowly.
