or we could get the familiar old periodic solutions of one planet orbiting around another one. and most importantly, changing the starting position slightly wouldn't change the behavior. but add some more objects to the situation, and suddenly all bets were off. other wild, non-periodic behaviors could happen, and moreover, slight changes in the starting positions could have very different long-term effects, although roughly, the bodies would still move in approximately the same region of space. poincare's discovery was astounding, but even more, the way in which he made this discovery was at least as important as the discovery itself. his epiphany was that the system of equations could be approached visually. to understand what poincare did, we have to understand a bit more about the problem. in classical mechanics, an object's position is recorded using its location in three dimensions: the so-called x, y, and z coordinates. when that object is moving, its velocity along each of these axes is also noted: velocity x, velocity y, and velocity z. when a second object is added to

so in our case, it could be actually to another planet. starting from these lagrange points, or the equilibrium points, they generate families of periodic orbits. so these are orbits that close on themselves, and they surround the lagrange points and they get bigger, bigger, and bigger. and what happens, these are very special types of periodic orbits that are very sensitive, or people call them unstable. but this sensitive dependence is really the definition of chaos. the very first mission that used this type of very sensitive orbits, and it was called the isee-3, international sun-earth explorer 3, was launched in 1978. by using the sensitive dependence on slight changes, it was able to reorient itself, move away from the l1 lagrange point, and actually go to follow -- to study a comet. and so it's this type of sensitivity and energy savings that makes these orbits very, very powerful. here we are in the jpl space museum, and behind me is a life-size model of the galileo spacecraft. what's really exciting for me is that even though the

let's suppose you're on this planet, the earth. and you wanna jump to another planet. and you're gonna travel between planets at a speed greater than light. now you can't do that. but let's make believe. and let's suppose up in this other planet here, you have a tripod all set up and you can stand there and look through and look right down through the path. and here you are down here. you're in front of a great big clock like einstein had in his village square. and what you do is you jump and you say, boom, shazam , okay? all of a sudden you become super-something, okay? and you fly up here. well, here you go on your trip when you jump up. first, you get here, then you're here then you're here and then all of a sudden, you're up here, okay? what would a trip like that be like? let me ask you a question. what would you or who would you see in the telescope? think about that. who would you see? what would you see? if you could go faster than light, faster than light, i know you can't do that, lee. let's make believe, let's make believe. if you could go faster than light

we know that there are billions and billions of planets.here are habitable zones that life is incredibly tenacious and that the makings of life are out there in the interstellar medium and that just like it fell on earth it is falling and other planets. i think that in a way the artist kind of is on this side that argues against it because the logic is so strong in favor of it. and so if you folks have questions i would be happy to answer them. i would talk about a study. two studies. okay. all right. what kind of life? is et going to be out there? i don't think so. these are calls not peace. far more likely that you will find some of these. the kind of algal map like this to light. if you can find out. it is put up by nasa. the plants in entirely different colors. plants that are entirely black. photosynthesis would just kind of a whole different physics to it. and, okay, we're talking about microbial life. maybe plant life or, you know, he matured. here is a problem. but everyone really, really wants to know is intelligent life. microbes

let's suppose you're on this planet, the earth. and you wanna jump to another planet. and you're gonna travel between planets at a speed greater than light. now you can't do that. but let's make believe. and let's suppose up in this other planet here, you have a tripod all set up and you can stand there and look through and look right down through the path. and here you are down here. you're in front of a great big clock like einstein had in his village square. and what you do is you jump and you say, boom, shazam , okay? all of a sudden you become super-something, okay? and you fly up here. well, here you go on your trip when you jump up. first, you get here, then you're here then you're here and then all of a sudden, you're up here, okay? what would a trip like that be like? let me ask you a question. what would you or who would you see in the telescope? think about that. who would you see? what would you see? if you could go faster than light, faster than light, i know you can't do that, lee. let's make believe, let's make believe. if you could go faster than light

off to a distant planet over here. and people on this distant planet are gonna have a telescope all lined up here and they're gonna stand right here and they're gonna watch the flashes of light. and let's suppose a person here emits a flash of light every three minutes. this little flash, flash... i got a question for you. if there's no relative motion between the two planets, it's gonna take some time for that first flash to get up here. but under zero gravity here, boom, sees a flash. how long they're gonna have to wait for another one? three. - and the next one? - three. - and the next one? - three. they'll come at regularly spaced intervals, all right? now, let's suppose i have a rocket ship that's traveling at a very, very high speed between the two planets. now, this rocket ship is traveling away from the planet, the source of light. will that rocket ship see the flashes as often as three minutes apart or more compressed to more often than three minutes apart or kind of stretched out? check your neighbor. see, th

and totally black sky and seeing another planet, planet earth. planet earth is only four times as large as the moon. so you can really still put your thumb and your forefinger around it at that distance. so it makes it look beautiful. it makes it look lonely. it makes it look fragile. you think to yourself just imagine the millions of people living on that planet and don't realize how fragile it is. i think this is a feeling everyone has had and expressed it in one fashion or another. but that was an overwhelming feeling in seeing the beauty of the planet on the one hand but the fragility of it on the other. >> being alan shepard, of course, shortly after that golden moment, you decided to play a little golf. >> i didn't decide to play a little golf. that is a long story. woint tell the whole story. >> tell us what you think might be all right. it is a very famous story. i'm sure a lot of people would like to hear your version of it. >> well, as you know, so far i'm the only person to have hit a golf ball on the moon. probably will be for some ti

and they are giving us a very strong signal that the planet is warming.nd the glaciers are disappearing. like looking at an area like this. you may have known where you were, but... we first went to kilimanjaro in 1999. and in 2000, we had aerial photographs -- flown -- so that we could make a map of the ice on the mountain in 2000. and it's when we started comparing the results of that map with all the other maps that had been made from the mountain, going back to 1912, that you could really see the loss of ice that has occurred there. and some of the skeptics will look at a mountain like kilimanjaro, and they say, "well, how do you know that it's not land-use changes, "changes in moisture supply -- droughts and the like?" and the answer to that is that it's not just kilimanjaro. it's mount kenya. it's the ruwenzoris. it's all the glaciers in the andes of south america and throughout the himalayas that are giving the same message. so the confidence comes from this large scale evidence that all points in the same direction. to me -- and particularly the t

, a planet that is fundamentally different than the one we grew up on.egraded planet for our children and grandchildren. for me that is a problem of ethics. and so i think that's where i believe it, and i'm happy to open it up for questions now. thanks. >> anything. no holds barred. >> there are a lot of people who are detractors. does it seem like this research opens all source of opportunities for different kind of -- [inaudible] why has it been so difficult for people to see the opportunities because i don't know. it's frustrating because as we all know other countries are moving ahead of us. we are falling behind. china is investing or more in renewable energy technology, solar technology than we are, as were many other countries. europe, india. we are falling behind and the rest of the world realizes that the future is going to be in non-carbon-based sources of energy. and transitioning away from our current reliance on fossil fuels is a limited supply of fossil fuels. we know we are degrading the planet through our use of fossil fuel to the rest of

we have the one planet we have there nor more places to exploit. so from now on, our innovations have to be in the direction of efficiency, conservation of resources, recycling, and the development of renewables. and so i hope that crosses the contradiction you say. >> ron barren. two questions. number one, you haven't said anything about water. and number two, with the focus on cities, which makes a lot of sense, with respect to energy efficiency, in light of the arab spring, what would you anticipate in terms of political turbulence as a result of heavy concentration of people, particularly young people in cities. >> thank you. i actually did refer to water once. i talk about food, future food scarcity. and land scarcity, and the problem that most of the lands that now rain-fed is in use, and i worry about the future availability of water for irrigation, because of climate change. so water is a very big concern. absolutely. and providing water to cities is going to become an especially big concern. and i worry about the struggle we're going to ha

. >> only a few years ago, the nobel prize winning scientists of this planet joined together in a major statement in which they called on the religious leaders of the world. now these are incredibly sober minded, well informed scientists who don't-- are not hysterical types they are not persons who tend to exaggerate their claims, but they came together with one mind and they called upon the various religious and spiritual leaders of the world, to realize what a critical time we are in right now in the history of this planet. they pointed to a number of the problems which face us as a species and which threaten not only our existence, but the existence of all of the other species that are here with us. and they called upon the spiritual leaders to begin to corporate and find ways to become a united force for compassionate action toward a just and sustainable human future. now, this declaration by these nobel scientists was not widely publicized, and yet it shows i think for us in a nut shell that we are in a very decisive time in history. most of the well informed persons that i know, i

debt bomb explode across this planet and we find out there's a quadrillion dollars of notional value derivatives floating around the world that's going to choke this planet in debt the people like jamie diamond will sit there and say we're doing god's work we're doing the best we can do feel sorry for the people who are going to pay are the people who are paying now the fifty million people on food stamps the million who are close a year the people who are falling off the unemployment rolls after two years of the emergency unemployment benefits of people are becoming non-persons one point two million of them in the month of january coming off the participation rate we are the ones paying for this these people doing as god's work are standing before a camera and i think when that cameras are there slapping each other about on the back and say look we got away with yet another one and charlie you mentioned just a little bit ago that it's sort of a misnomer to think that this is a. a red problem versus a blue problem that that one of the two parties will come in and clean this up and sa

, a planet that is fundamentally different than the one i grew up on, integrated planet for childrenand grandchildren. and so, i think that is where i'll leave it. i'm happy to open it up for questions now. >> anything. no holds barred. [inaudible] >> it seems that this research had all sorts of opportunities in different ways. why is that so difficult for people to see the opportunity? >> other countries are moving ahead in were falling behind. china is investing far more in energy the energy technology, solar to elegy than we are. so are many other countries. europe, india. we are falling behind in the rest of the world realizes that the future is going to be in transitioning away from our current reliance on fossil fuels. there's a limited supply of fossil fills me know if they are degrading the planet to our use of fossil fuels. the rest of the world gets it and i think many here in the u.s. get it, too. it's just that it hasn't quite -- it hasn't seen through to the highest level of decision-making and our political process. you know, i think that there is this false choice that

you know why the planets are round? because if there are great, big cubes the corners could be pulled in by gravity, gravity pulls everything in until it gets round. the whole universe, it turns out the idea of gravity underlies our thinking about the universe. you guys hear about the big bang theory? the idea that about 14 to 20 billion years ago the whole universe was in one point and exploded out, all flying out. let's look at that in terms of the gravity bit here. let's suppose, here's the big bang and all these pieces are flying. now let's suppose that we knock the whole universe into four halves just to make the thinking easy. if we can understand the simple examples then maybe we can deal with complexities. here's part of the universe here, here's part of the universe here, part of the universe here and all are flying apart. there's nothing else that exist just this and there they go. any force of attraction between these phases? how many say, yeah? it turns out this would be attracted to here, this would be attr

we are wiping out the planet and the public is left holding the bag. we definitely need something completely different. putting the moral outrage aside for a second, this situation also puts cities at great risk. we've only gotten a taste of the destruction that -- disruption as possible with the numerous revolutions that broke out. the crisis will land hardest in cities. i see city's borrowing language from complexity theory, i see the boys and a critical state. it is a new situation. 50% of global population is urban, young, and connected by mobile phones. the young are the hardest hit here. in spain, the unemployment rate for young adults is around 50%. in the united states, college graduates are leaving school with an average of $24,000 in student loan debt into labor market for their age group that has not been as bad as it is today since the depression or the 1940's. the smallest thing can trigger a crisis now. it is a powder keg. on the other hand, along with this crisis is a powerful new set of tools that have arrived so breakthrough is also po

in this edition, we look at the business of powering the planet. we meet a group of overnight millionaires getting rich from gas dug out of rocks. we also take a look at the financial promise of an emerging science known as synthetic biology. and finally, we examine an alternative car fuel that you probably never heard of: laptop computer batteries. we begin with an unconventional process for extracting natural gas from shale, a dense rock formation two miles underground. it's being touted as the hope of the future, the answer to our energy problems. and if you're sitting on top of it, you may become a new american phenomenon: a shaleionaire. and yet, as we all know, exploring for energy has safety risks. but as we first reported in the fall of 2010, that can get lost in all the excitement. what's increasingly evident is that shale gas is overwhelmingly abundant right here in the usa. >> in the last few years, we've discovered the equivalent of two saudi arabias of oil in the form of natural gas in the united states. not one but two. >> we have twi

worth of everyone in the world consume less people in america than we need for planets to sustain to sustain that level of consumption which we don't have that and yet they only achieve in terms of wellbeing in terms of life satisfaction life expectancy the lower life expectancy faction than a country like costa rica which consumes one quarter of the resources so that gives you brings you know the dimension of efficiency so if there are some things that some countries are doing which is inefficient in terms of converting environmental resources into wellbeing that's something those countries need to be looking at christopher so let me let me pose it just way in light of what summer just said so britons of americans should consume a large large ok let's cut it in half what's got out seventy five percent of it or they could be happier people. i would very much doubt and i don't know people perceive happen isn't the people he expects to i have a better lifestyle than their parents did and we've been expecting that for several centuries thanks to consume a couple is making that possible

and by twenty fifty the planet isn't getting any bigger the amount of resources we're having is in fact getting less and we do need to start thinking a little bit more seriously about whether we have enough resources to achieve the kind of quality of life that some people at least have been enjoying in the in the beginning of this century and the last century and the evidence just that we don't have enough and that's one of the reasons why we do have to start thinking about the well being dated a bit more bit more seriously because we have to actually start thinking well there's a lot of people here who are consuming a lot of resource consuming a lot of resources so for example in the last the last ecological footprint analysis americans consume let's say four planet's worth of everyone in the world consume less people in america than we would need for planets to sustain to sustain that level of consumption which we don't have that and yet they only achieve in terms of wellbeing in terms of life satisfaction life expectancy the lower life expectancy faction than a country like costa ric

danger right it turns out the government agency was actually instrumental in helping the craven five planets terrorist bridge plot the entire event was provoked and orchestrated by agent provocateurs who supplied the motive and the means to carry out the plot now f.b.i. entrapment in terrorism cases is nothing new the agent currently has fifteen thousand undercover operatives in their ranks who get paid as much as one hundred thousand dollars per sign meant at least half of the latest five hundred prosecutions related to terrorism have involved f.b.i. entrapment so the question remains when the f.b.i. foils its own terrorist plots are they preventing terrorism or they just creating
