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 first one is that these little 18 month-old babies have already discovered this really profound fact about human nature, that we don't always want the same thing.
But if we turn to evolution for an answer to this puzzle of why we spend so much time taking care of useless babies, it turns out that there's actually an answer.
We're smarter, we're more flexible, we can learn more, we survive in more different environments, we migrated to cover the world and even go to outer space.
We need to redefine leadership as being about lollipop moments -- how many of them we create, how many we acknowledge, how many of them we pay forward and how many we say thank you for.
So even though we love publishing as an art, we very much know it's a business too, and that if we do our jobs right and get a little lucky, that great art can be great business.
That's one of the reasons so much of what we've come to think of as Western science and mathematics and engineering was really worked out in the first few centuries of the Common Era by the Persians and the Arabs and the Turks.
Evolution did not prepare us for this. We just don't have the bandwidth, and for people who say, oh, they're having a nice day, they're perfectly fine, they're more insane than the rest of us.
Our first project, the one that has inspired my first book, "Ripples from the Zambezi, " was a project where we Italians decided to teach Zambian people how to grow food.
私達がこれまで ― （拍手） 私達がこれまで 純真なアフリカの人々に 与えたガラクタを見てください
You should see the rubbish — (Applause) -- You should see the rubbish that we have bestowed on unsuspecting African people.
I shut up, and listen to them." (Laughter) So — (Applause) — So the government says, "Do it again." (Laughter) We've done it in 300 communities around the world.
We've done the research, and we have looked at the 100 iconic companies of the world -- Carnegie, Westinghouse, Edison, Ford, all the new companies, Google, Yahoo.
But now we want our partner to still give us all these things, but in addition I want you to be my best friend and my trusted confidant and my passionate lover to boot, and we live twice as long.
Because they weren't with us on the sidewalk, and they couldn't see the exchange that was happening between me and my crowd, an exchange that was very fair to us but alien to them.
So blogging and tweeting not just about my tour dates and my new video but about our work and our art and our fears and our hangovers, our mistakes, and we see each other.
What if you're only going to be anonymous for 15 minutes? (Laughter) Well, then, because of electronic tattoos, maybe all of you and all of us are very close to immortality, because these tattoos will live far longer than our bodies will.
(Laughter) We all create our own lives through this restless process of imagining alternatives and possibilities, and one of the roles of education is to awaken and develop these powers of creativity.
Well, it is the most important aspect of our lives for a very simple, logical reason, namely, it's a necessary condition on anything being important in our lives that we're conscious.
Watch. I decide consciously to raise my arm, and the damn thing goes up. (Laughter) Furthermore, notice this: We do not say, "Well, it's a bit like the weather in Geneva.
Okay, the second feature is this one that has been such a source of trouble to us, and that is, all of our conscious states have this qualitative character to them.
Dear brothers and sisters, we were striving for more rights for women, and we were struggling to have more, more and more space for the women in society.
While my daughter was on the verge of life and death, I whispered into the ears of my wife, "Should I be blamed for what happened to my daughter and your daughter?"
If you go back 50, 000 years to the Paleolithic era, to the early days of Homo sapiens, what we find is that the world was filled with danger, all of these forces working very, very hard to kill us.
You see, if the conditions are wrong, we are forced to expend our own time and energy to protect ourselves from each other, and that inherently weakens the organization.
We can try and render the chains of mass surveillance invisible or undetectable, but the constraints that it imposes on us do not become any less potent.
Maybe, because employers are coming to me and saying, "We have already raised a generation of young workers who can't get through the day without an award."
And her story highlights for me that when we seek the gaze of another, it isn't always our partner that we are turning away from, but the person that we have ourselves become.
Well, our genes are not our fate, and if we make these changes -- they're a predisposition -- but if we make bigger changes than we might have made otherwise, we can actually change how our genes are expressed.
But the point is, this is the same situation that can inflame the hostile imagination in some of us, that makes us perpetrators of evil, can inspire the heroic imagination in others.
And my brother and I were raised with all that you really need: love, strong values and a belief that with a good education and a whole lot of hard work, that there was nothing that we could not do.
And my mother, the most important role model in my life, who lives with us at the White House and helps to care for our two little daughters, Malia and Sasha.

Cruelty: I knew that the 10 billion animals we raise each year for meat are raised in factory farm conditions that we, hypocritically, wouldn't even consider for our own cats, dogs and other pets.
When we released that report, we did so three days after the new president, Kibaki, had decided to pal up with the man that he was going to clean out, Daniel arap Moi, so this report then became a dead albatross around President Kibaki's neck.
But there are legitimate secrets -- you know, your records with your doctor; that's a legitimate secret -- but we deal with whistleblowers that are coming forward that are really sort of well-motivated.
Should they come forward, that would be a tricky situation for us, but we're presumably acting in such a way that people feel morally compelled to continue our mission, not to screw it up.
And we got a report -- a sort of engineering analysis into what happened -- saying that, in fact, security guards from some rival, various competing oil firms had, in fact, parked trucks there and blown them up.
So what this means, this incredible freedom of choice we have with respect to work, is that we have to make a decision, again and again and again, about whether we should or shouldn't be working.
