kinetic, yeah. kinetic energy, okay? and then we can talk about-- later on, we can talk about heat energy, sound energy. can anyone think of any other kinds of energy? how many said, "no, that's probably it, there's probably no more?" come on, gang, some more. light. light energy. - thermal? - tension? good, radiant energy. radiant, from radium, things like that, huh? - thermal. - good, thermal energy. good, nuclear energy. and turns out energy of being. it turns out everything has this quantity called energy. and that's given by einstein's celebrated equation. later in the course, we'll talk more about this, the idea that energy and mass are two sides, gang, of the same coin. you guys get mass, right? you know what your mass is? [makes sound] squashed up energy. you are all bits of energy all squashed up. and the more massive you are, the more energy you'll have. and sometimes you can convert from the inertia kind to the radiant kind. and that's what happens in the sun and the stars. and that's the energy of fusion. and

kinetic energy, very, very big down here. kinetic energy, very small up here. oh, it looks like the conservation of energy-- - what kind? - potential. potential, over here, very, very close. it's got a little small potential on over here. over here, very, very far, gotta big potential energy here. add these two up, you get a number, add these two up, you get a number. everybody in here know how this total number compared with this total number, right? 'ss' same, same. --ain't that neat? all along here, the total energy stays the same. yum? what happens when we hear that a russian satellite has crashed in australia or in canada, what really happens to the satellite? sometimes these satellites, they're falling all the time, by the way, but sometimes they fall and get closer. how come that happens? - air drag. - air drag. they drag their feet in the air. here's a satellite, i mean i say that not literally. here's satellite plowing through, okay? now it's way, way up there, maybe a couple of hundred miles high, no air drag. but maybe sometimes it's in kinda low orb

not a kinetic but a computer network type attack attitude.in computer network attack, that comes an area we need to focus on and have some specific targets to go after. now, is something, while we have the capability of doing that, we don't do that unless we get presidential authorization to do that. and that in its big sense has never really happened. adam: so our options as you said earlier, trade sanctions. but do we even have the ability, as the biggest trading partner with china, europe is their biggest trading partner, but such an important part of our economy, do we have the ability to do trade sanctions without hurting ourselves in the process? >> that is always part of the problem. there are certain good, for example, t-shirts or something like that, they will come in, you know, from china at a very cheap rate but there are other countries that produce the same kinds of goods. if you go after it. shirts, say get them from vietnam instead of china, then you have an alternative supplier and you can circumvent the chinese system. there

move of course the entire region i think all these advances though they're not one farm the other kinetically they're all part of a change i look at the situation now with france taking the lead in mali and with that cool if you knew the activity there so you have to see right now that you've gone from one combustible situation to another and while he sat there with these are being fueled by a horrendous horrible foreign policy coming out from the west and from the obama administration and the worst thing we're doing which is impacting the situation in turkey is working without qaeda in turkey for the overthrow in syria or for the overthrow of bashar assad but this is a very very dangerous policy and i believe this is directly connected other much you know evidence yet to what took place in turkey in the last twenty four hours all right lawrence freeman for me is that intelligence for your magazine thanks for i thank you. and more news still to come in a little more than a minute stay with us here on r.t. . here the reindeer is interesting for the herders. and when it suffers. people do their

striking and meet the drones, or whatever you do, kinetics strikes and things like that, because you can disrupt the organization and take out key leaders. i have never seen it where it isi have never seen where you can do enough drone strikes to destroy an entire network, or decapitate it enough so that new leaders do not rise. i hope that is not the whole. i think it has got to be a supporting efforts for other activities, hopefully by the government of yemen. what we have to understand about drone strikes is for every action there is an equal and opposite reaction. every time you shoot inside a country, there are some who are happy about it and some who are not. often, those who are not happy about it are not directly affected by it. if you look in pakistan right now, those who are most opposed to american drone strikes are not those who are close to the strikes. they are people in other parts, by the idea of sovereignty being violated. that is something we got to something. there is always a day after. and you will always deal with the long-term impact of what you do. i do not be

the kinetic energy, it's turned to heat. this is this enormous shockwave.w how fast the molecules are going between you and me right now? take a guess. >> cenk: i'm going to guess super fast. >> there is a round number that you can use. >> cenk: 1 million a second. >> it's the speed of sound. >> cenk: i feel like i'm back in physics class and getting every question wrong. >> this pushes on the molecules much faster than their natural speed, the speed of sound. there is a shockwave that is hot and high pressure and that's what blew out all the windows. so it's spread out quickly. then if the thing hits the ground then you have meteor created, and there was a meteor in iowa, if you've ever been in the united states. there is so corrosion wind, rain. >> cenk: i didn't know iowa had been hit. i thought it was only russia. >> have you heard of the tungusta event. >> cenk: 1908. >> yes. the air burst blew down all the trees in an instant. in an instant. >> cenk: i have more amazing facts. first of all 82 million trees were wiped out by that meteor according to 82

it is not just a kinetic solution. as we look at the sahel, this is an area where al qaeda can put down roots beyond the reaches of government. they have done this and it has been unattended because of the difficulties these countries have feeding their people. it is a different strategy -- but al qaeda -- and the force of islamic extremists that have preferred it are making some progress in areas that give me a real concern. that is why looking at syria and what is going on in that country, we cannot allow vast areas to be exported by al qaeda in these areas because it will be to our peril. >> i certainly agree with you on that, and in our testified hearing next week i will ask you about syria and also the iranian threat. i do not think those are appropriate in open session. just two final questions -- one has to do with priories that you have said. in recent years paramilitary operations had consumed a lot of resources, expertise, time, energy, and efforts at the cia. do you believe this has been at the expense of tr

that was a point where you avoid a cyber weapon that made, that had a kinetic effect that took out part of the nuclear processing facility. that's a very big deal and the word changed after that. >> rose: mike hayden has told me that the chinese spy on us more than any other country by far. >> sheer numbers that's probably true but again, you know, it's because they do both traditional spying and they do a vast vacuuming up of ideas from and research from corporations of just about every sort. it is a huge operation and a lot of data is being taken. there's a question, you know, it does raise some questions about how effectively that data can be used. some people say that the amount of theft is so bad that it's hard to imagine how you could process that amount of information usefully. >> rose: processing data has become a big question here. david brooks has written a couple columns about that. finally this, where do you go from here on this story? >> well, i personally, you know, in reporting on this, mike has actually done a lot more work than i have on this but i keep on asking for go

just had to wait until it faded away, the kinetic effect.an tell you it'll never fade for the memories of the families who lost their children and loved ones in connecticut. it'll never fade from the memories of those folks in the region. it'll never fade from the member riff the people of connecticut. and i've noticed, look what the legislature did in colorado. what it's about to do in new mexico. it's a different time, guys. it's a different time. >> the vice president talked to the national association of attorneys general today. continuing his tough push for stricter gun laws in the country. all this is going on as the senate judiciary committee is holding a hearing on gun violence. and the newly reintroduced assault weapons ban. i want to play an exchange between the milwaukee police chief edward flinn who was a proponent of the assault weapons ban and republican senator lindsay graham. take a listen. >> just for the record from my point of view, senator -- >> how many cases have you -- >> it doesn't matter. it's a paper thing. i want t

she's kinetic, exciting. she will bring the house down when she shows up there.t romney -- nobody has asked for an encore from him. but this regular crowd of newt gingrich, who seems to be freddie kruger, he will never go away. >> what's the definition of insanity, doing the same thing over and over and expecting a different result. this is what we're seeing at cpac. >> i think they say that at alcoholics anonymous too. >> well, cpac is the warm, emotional, beating heart of the republican party. not necessarily the brains. i don't mean they're stupid, i mean they're not looking for cool intellectualism here. they are looking for people who will appeal to the emotional heart strings -- >> would they rather win with a mitt romney? >> they would rather lose with a purist than win with a pragmatist. >> go with that, john. a lot of liberal democrats enjoyed add lie stevenson because they had the awareness he's a lot smarter than ike, although i'm not sure he was. would you rather win or be right, far right? >> there's no reason we can't be both. look at the governors

it's been a very fast paced kinetic activity, gunfire at this roadblock and at the cabin you see now. it is getting dark. that had been a concern for law enforcement. tom fuentes is joining us. from a law enforcement standpoint, the darkness was a concern all along. it would seem once they realized that there were not hostages inside, as we believe there were not, although that's not been confirmed, because the cabin was said to be empty when christopher dorner went in, it would seem as if the darken was a real concern. law enforcement wanted to try to move in as quickly as possible before darken fell. chris voss is a former hostage negotiator. do you think that's fair that darkness was a concern here? >> the main concern in terms of darkness is whether they've got their inner perimeter established. they're more concerned about getting that. it's tougher when it's dark. that's the real concern. if they establish their perimeter they're prepared to deal with the darkness. they've got counterterrorism training. they can handle that but it was making sure their perimeters are established

house is a lot of other state of the union addresses, there's some in history that have been very kineticortant going back to, you know, james monroe in 1823 with the whole monroe doctrine, protection of the western hemisphere was from the state of the union. lyndon johnson launched his war on poverty if his state of the union, and george w. bush famously with the axis of evil pointing out iraq, iran and north korea as being our seminal and main enemies. but there are moments when these states of the union matter, but this one is going to have to be focused on jobs, on employment, on how to get the economy going again. president obama did not touch on that theme during his inaugural address, so everybody's expecting he will try to make this a major economic statement and also deal with newtown and gun control as key components of this address. arthel: and the president is believed to, expected to rally the troops, get the americans involved in the democratic process. so how does he rally congress and get them engaged in the process of law making? >> well, you know, state of the unions hav

to fight for all the united states needs to maintain their nuclear security access, both human and kinetic. until such a time it is appropriate to move multi- laterally towards a nuclear 0. as you know, the president says that will take patience and persistence and it may not happen in his lifetime, and he's a lot younger than i am. i think that we have to keep in mind that we should not commit to an arsenal and a complex that congress is not willing to fund in a predictable and consistent way. maintaining a safe and secure deterrent requires consistent, steady funding from the congress, even in an austere environment. yet, the members of congress to take a truly significant interest in nuclear weapons continues to dwindle. for most members, there is no base constituency. most members are stretched thin to represent over 730,000 people. for those with a nuclear complex facilities, they need to be supported. they number less than a couple dozen and that is counting on the senator's. hardly a short march to the 218 votes needed in the house or 60 votes needed regularly in the senate. again a

that's the fear, making nonkinetic violence kinetic violence. is probably going too far with the cyber threat. >> david, have you, talking to your sources in washington, what is their thinking about this? is it as brandon says that they're ready to go hard if they get hit with the stuxnet type virus? >> i think i've heard something a little different. if you read the pentagon policy, it is that they would use proportional force and they have not said whether or not it would be a return cyber attack or whether it could go to conventional. i think they want to leave open the possibility that it could go conventional. the reality is that every cyber attack that i'm aware of that the united states has ordered against another state, and iran has been obviously the biggest case, there were some minor cases during the iraq war and i think a few uses in afghanistan, have had to go to the president. and in fact this is considered a weapon like nuclear weapons and to some degree like drone attacks, where the president has got to sign off on specific uses,

or ways because i'm not positive, but a large meeting recently said he expect good an opponent or kinetic effect to fade. he just had to wait until it floated away. george can tell you it will never fade from the members of the families who love their children and loved ones in connecticut. it will never fade from those folks in the region or the members and people in connecticut. but with the legislation did in colorado, what it's about to do in new mexico. it's a different time, guys. it's a different time. and that good news for you. it's not going to fade into memory as the american people. the nra and organized opponents are using a simple tactic they've used against me and others for years in the congressional gun policy. a gun policy does nothing but infringe on the second amendment. they serve question after question, not because they are looking for answers, not because they're driven by the facts are looking for a way forward, but because they are looking to build roadblocks. for example the president is recommending to the nation going after law-abiding citizens. we are not. th

isn't actually deterrents and static, but the questions of the behavior of the various actors in kinetic situations and escalation, control of escalation processes, and far too much has been focused on deterrents as a static process and much too little on escalation and die name is -- dynamics in various contexts. averting the nuclear middle east, i raised a question regarding confidence. i personally, from my experience in the middle east, i think that i -- american -- the confidence in the american nuclear deterrent towards a potential iranian nuclear threat to the countries of the middle east, in other words, confidence that the american extended deterrents is enough to prevent other countries from going nuclear is actually at the lowest level that it could be. there is no such confidence. i think that's it's a by gone conclusion that when iran is perceives as coming, finally close to a nuclear capability, then saudi arabia, turkey, egypt, and other countries will move forward. this will, of course, raise the question of israel's nuclear posture, which, according to foreign press isra

it is not just a kinetic solution. as we look at this hell -- at sahel, this is an area where al qaeda can put down roots beyond the reaches of government. they have done this and it has been unattended because of the difficulties these countries have feeding their people. it is a different strategy -- it has become prats of one, but al qaeda -- and the force of islamic extremists that have preferred it islam are making some progress in areas that give me a real concern. that is why look at syria and what is going on in that country, we cannot allow vast areas to be exported by al qaeda in these areas because it will be to our peril. >> i certainly agree with you on that, and in our testified hearing next week i will ask you about syria and also the iranian threat. i do not think those are corporate in open session. just two final questions -- one has to do with priories that .ou have said in recent years paramilitary operations had consumed a lot of resources, expertise, time, energy, and efforts at the cia. do you be

the question is the behavior of the various factors in kinetic situations and escalation -- control of escalation processes. far too much has been focused on deterrence as a static process and much too little on escalation and the dynamics of escalation in various contexts. i raised a question regarding competence. from my experience, i think that confidence in american nuclear deterrence toward a potential iranian nuclear threat to the countries of the middle east -- in other words, confidence that the american extended deterrence is enough to prevent other countries from going nuclear is actually at its lowest level that it could be. there is no such confidence. i think it is almost a bygone conclusion that when iran is perceived as coming finally close to a nuclear capability, then saudi arabia, turkey, egypt, and other countries will move forward. this will, of course, raise the question of israel's nuclear posture, which, according to foreign press history seems to that,- i don't know about of course. we tend to see nuclear weapons as something devastating, something totally last

actually, deterrence or static deterrence, the question is the behavior of the various actors in kineticsituations and escalation, control of escalation processes. and far too much has been focused on deterrence as a static process, and much too little on escalation and the dynamics of escalation in various contexts. so, first of all, the chances of averting a polynuclear middle east, i raised a question regarding confidence. i, personally, from my experience in the middle east i think that america -- the confidence in an american nuclear deterrence b towards a potential run yang nuclear threat to the countries of the middle east, in other words, confidence that the american extended deterrence is enough to prevent other countries from going nuclear is actually at the lowest level that it could be. there is no such confidence. i think that it's almost a bygone conclusion that when iran is perceived as coming finally close to a nuclear capability, a military nuclear capability then saudi arabia, turkey, egypt and other countries will move forward. this will, of course, raise the question

measures, but the nra a couple days ago called what happened in connecticut and the aftermath of the kinetic effect, i think is an unfortunate way to put it into the extent that the gun lobby thinks that the desire for gun-control is going to be saved, i think they are wrong. i hope we get it in the coming months, and an appetite for strengthening gun laws to protect kids and families for a long time. >> your fellow democrat from connecticut have issues and recommendations, working on gun issues. would you like to see the white house do and what the senate and the congress can relatively do? >> i think it is the strongest bill possible. i'll see any reason why they should be on the streets today. i don't think that any law- abiding citizen needs and magazine filled with 30 rounds for 100 rounds in order to go out and enjoy their sport. we need to say that weapons designed to kill people should stay in the hands of the military, weapons designed for that should be in private hands. that is part of the to do. in the background check side of the equation, but just as important as far as i'm con

it is not just a kinetic solution. as we look at the sahel, this is an area where al qaeda can put down roots beyond the reaches of government. they have done this and it has been unattended because of the difficulties these countries have feeding their people.it is- but al qaeda -- and the force of islamic extremists that have preferred it are making some real concern. that is why looking at syria and what is going on in that country, we cannot allow vast areas to be exported by al qaeda in these areas because it will be to our peril. >> i certainly agree with you on that, and in our testified hearing next week i will ask you about syria and also the iranian threat. i do not think those are appropriate in open session. just two final questions -- one has to do with priories that you have said. in recent years paramilitary operations had consumed a lot of resources, expertise, time, energy, and efforts at the cia. do you believe this has been at the expense of traditional cia responsibility collection, analysis? >> the
