mass. mass. and the nucleon will have more energy which is to say, equals-- which was easy to say will have more mass outside the nucleus than inside. and in there lies the secret of nuclear energy because the graph of the nucleons would be something like this. over here 92, there's the graph that really, really tells it. and it's a graph, mass per nucleon versus atomic. now, it's not the mass of the whole atom, mass of the whole nucleus, it's the mass of each nucleon in the nucleus. and you say, in hydrogen it has the most mass of all. none of its mass is bound up with energy or binding anything else with it, it's all by itself. and as you continue to go up the periodic table, you get varying amounts of mass per nucleon. the point is, how much mass you got? depends per nucleon, depends what nucleus you're in. let's look at the uranium fission in terms of this relationship. here's uranium right here. the uranium atom has nucleons which have about this much mass each, each, all right? what's gonna

so force per mass. now as you're pushing faster and faster and faster and the mass becomes more and more and more, what happens at the speed of light? at the speed of light, what would the mass be? see this little piece of chalk. what's the mass of this piece of chalk if i push it to the speed of light? i can use this equation to guide me. if v is the speed of light zero...infinity. this mass will be pushed to the infinite. now someone says, now that it has an infinite mass, which means an infinite resistance to any further change in motion. now if someone says, could you push it in hyperdrive, honey? hyperdrive, i've got an infinite resistance to any change in motion now. and so we find out in the universe as we understand it in the 20th centur you can't do that. at least with material particles there is a speed limit, the speed of light. so you get that down. one of the important parts of relativity is this. before we understood relativity, we understood that the human race, no matter how sophisticate

hamas in gaza because the syrians and both sides are paying the price for this confrontation is a mass deliberately sacrificing its own people by using civilians as human shields . i don't think about this is our place size difference. of what is going to really. have to a very in mind. the civilians in gaza strip for more than five years of blockade from a siege and the israeli occupation actually it's effectively israeli occupation kl call it for the civilians in gaza how many calories whole money food we consume this is not a normal situation the civilians in gaza really suffer from this continuing situation but you are sorry to interrupt i was saying. that there is a delay here you're saying that negotiations should be pursued but while the mass continues to fire rockets into israel doesn't israel have the right to defend itself what else should it be doing when it's still receiving these rocket attacks from that. well i believe really in the right of self defense for both sides you cannot emphasize the importance of. self defense right against missiles which hamas fired on israel

a lot of sentiment against out of total mass by people that are not sort of. his parties i guess immediate ideological range i mean he just had a general strike against him on the fourteenth of november that also drew nearly a million people into the streets so the problem with this is that between the the nationalist sort of sentiment and the anti austerity sort of majority view their opposition to a lot of the mass is either confused or doesn't really have a referential point in the form of a political party to vote against him so he sort of has the strongest group out of all the electoral formation well this election was called two years early all for a failure to convince the spanish prime minister to ease the tax burden on catalonia but this is the most prosperous region spain hell exasperated all the people that are actually with the financial crisis all they really that badly affected. they are strongly affected there is badly affected as most of the other regions in spain i mean the unemployment here is around that twenty five percent that is the unemp

i heard just in from the mass is still behind many of those rocket attacks though. yes the overwhelming majority of rocket attacks on israeli territory that pass through the green line down to hamas now where are you at the moment you said you heard some jets above you knowing that the media centers are safe so where you run oh yes well we're now in a makeshift media center in a car park here in west gaza city in what is meant to be the green zone but as you can just hopefully of hugs we said three or four explosions in the last one minute with you here we have sixteen drones continually flying above our heads here in west gaza city and what do you think those jets are aiming at at the moment you all obviously not far from where those explosions are can you have any indication as to what they're targeting. well they could be targeting for example political members of hamas they could be targeting people who israel thinks are responsible for supporting rocket fire sounds ready territory these are the supposed targets according to israel but earlier today we've seen a

what's the mass of an electron? zero. well, it's closer to zero than it is to one if one is the mass of a proton neutron. and this has got, like, about 2,0th the mass. that's closer to zero than to one. so we round off atomic mass number, anyway. this is zero. now, what does the thorium become? well, what do we got over here for an atomic number? 91 do you see it's 91? yeah. 91. and what's the mass gonna be? - 89. - now, what has 91? protactinium. - is it gonna be 91, gang? - yeah. let's check. - 91 minus 1 equals 90. - correct. it's 91. that's interesting. some people think that radioactive decay, you start with uranium and work down, down, down, down the periodic table approaching hydrogen. not true. when beta particles are emitted, you climb up the table, gang. you see that? what happens in that nucleus? you got all these particles in that nucleus. i'm not gonna draw them all, but we've got 90 of them, right? and take away from 234, the rest are neutrons, so you got a lot of neutrons. what happens is this. one of these

so, really mass transportation system is what saved the area longer. if there was an emergency evacuation, the mass transportation systems would be activated to get people out of the area. >> okay. and in terms of in the bay area, though, if that happened here. let's say for us, it probably would be, i don't have a crystal ball, but like a major earthquake that would all of a sudden, everything was on safety and you couldn't do it. is there a plan in place? >> absolutely. the metropolitan transportation commission has an emergency evacuation plan, emergency reaction plan. it was used in the 1989 earthquake. >> uh. >> and it was rephoned at that time. there are emergency plans. >> but. >> remember, the emergency plans rely heavily on mass transportation. >> right. >> the highways go down first. >> yeah, if the mass transportation is functioning to a certain point, at some point, if it all stopped as it has done because of sando the east coast, you said it will impact the economy. i would assume that we could not get everything up and running all of a su

what's its mass? - one. - one. those two things slam. and when they slam, boom, again, a proton pops up and leaves what? well, whatever it leaves, it'sotta be--what's the-- what it's goa be over here, gang? - six. - six. and what'she number gonna be? - 13 - 14. you see, it's 14. hey, this is not twice this. this is twe and then some. this atom here has extra neutrons. it turns out that atom is unstable. that atom is carbon 14. most of the carbon in your envinment is carbon 12, but somethe caon your environment is carbo14. and th carbon is radioactive. and that carbon emits a beta particle. could you tell me what is left? some people can. some people can't. most of you, of course-- begins with a c. can't. the shorter version of c. check your neighbor. what are the numbers gonna be, gang? what's the number gonna be over here? - seven. - seven? - is it seven? - yeah. - if it's seven, does it check? - yeah. seven minus one is six. what's seven? - nitrogen. - nitrogen. - what do we got for up here? - 14. what goes around comes around. nature

today we asked what mass incarceration means for our society.raises questions of race, class, and the meaning of justice. joining me, patricia williams. she a law professor at colombia university american work is to examine race in the american legal system. and michelle alexander, her book "the new jim crow" brought the conversation about mass incarceration to a wider johnson. and eugene jarecki, the filmmaker behind the movie requested the house i live inment. when we use the term "mass incarceration" what are we talking about? >> we're talking about a system that function primarily as a sufficiency racial and social control, rather than a system of crime prevention and control. you mentioned that there are more than 7 million people who are under correctional control-- in prisoner jail, on probation, parole. we now have the largest penal system in the world, a system unpose dented in world history. and although politicians may tell you the explosion in our prison population has been driven by crime or surging crime rates, it's actually not tr

protesters say they have no intention of leaving tahrir here for at least a week having announced a mass sit in the symbolic square people flooded the streets across the country angry at the president's decision to grant himself new powers to put in the power of other branches of government the opposition compared the move to a coup the latest comments from came from egypt's top judges who called it an unprecedented attack on the country's judiciary the demonstrations quickly turned violent as protesters clashed with security forces and probation activists ten years after the fact he believes that the opposition's concerns over the future of democracy in egypt have solid ground. what have mohamed morsi done mobarak in the height of his power could not even dream of achieving morsi is part of the muslim brotherhood and islam or fascist group do have control over their members and supporters it is very simple and the country was more than forty. five percent of its population are illiterate to control them in the name of religion gyptian is are now seeing clearly they have replaced the mil

is as are the claims that greg norman is making about how mass somehow a justification for mass murder by israel in the gaza strip whether in two thousand and eight two thousand and nine or today or in the next now peter you mentioned the seeds i mean there are underlying factors here there is the occupation there is the continuously deprived right of self-determination of the palestinian people and of course in more recent years there is a siege and blockade of the gaza strip that's the context what we're seeing now is a symptom of the cause rather than the cause itself. which i do replied i greg. sure the first of all the newspaper was al-hayat the second of all accusations of mass murder. you know unnecessary to make because what's happening is israel's defending itself now if you're asking why less israeli civilians have died then civilians in gaza it's because israel actually cares about its people and has developed active protection systems to make sure that those rockets that are being fired at israeli civilian targets israel just to. have some interest and no doubt. that the th

you don't want mass producing. today industrial 3d printers and my robot company, fantastic, at home we have makerbought and it is pretty crude mica dot matrix printer, the ones you buy at home take a filament in plastic, the same stuff you use for lego and melt it and squeeze it out and there are other ways, liquid resin, powder, etc.. you can go to a site where they have 3d printers and you cannot -- upload the same design, stainless steel, the quality is astounding. 3d prints, turbine blades for jet engines. there are limits to what you can do with a 3d printer but not many. the question is simply how long will it take? 15 years to get from dot matrix to photo quality ink jet on your desktop. we are not matrix phase right now, how long will it take? i don't think it will be 15 years. in part because it shares the same mechanical technology as an ink jet. the 3d printer is x why is the. interesting stuff gets into materials. right now in my printer we can do one, in plastic, pretty low resolution. the next one, t

you elected to mass have mass regime governs the strip whatever happens that's your problem now historically over the last few months and years have masses not been able to control many of the military operations of the different resistance groups here the gazans call them and so actually it's been all the time i've been hearing israel is targeting hamas but hamas is not gaza why are they targeting gaza hamas and gaza are not the same thing now speaking today there are massive reconciliation attempts reunification attempts rather excuse me in central gaza city between fatah between hamas between other factions p.f. lp for example as well so what's happened is seeing is these military operations against israel over the war over the water fairly unified they stood together the military groups and the militant groups now after the war they're now getting towards a political position of doing the same thing less less fragmented ok i mean it's very interesting this is the second time they've tried to destroy hamas and they have failed i mean. come out of this. well again i think precisely because

glaciers are large, long-lasting masses of ice which slowly flow across the land.hile most places periodically have temperatures cold enough for snow and ice to form, only in a few places do conditions permit the growth of glaciers. glaciers come from the accumulation of snow, either in polar regions or in high altitudes, or even at the equator at very high elevations at the tops of mountains. wherever you have precipitation in the form of snow, you can get a glacier. but there's one other requirement-- more snow has to fall in the winter than melts in the summer, so that in every 12-month period, some of the previous winter's snowfall is left over. so as snow accumulates year after year, a glacier begins to form. the actual manner in which snow is converted into glacial ice involves compaction and rearrangement of snow crystals. there's a process that goes on as each layer of snow is added year by year-- that's residual snow from the previous winter-- it compacts under the weight of new snowfall. and as that compaction takes place, the snow crystals are pressed cl

so you'll have to use a new set of mass production technology. so the good news is, i actually went back to 1972 -- it is probably more appropriate to go back to 1984 with the macintosh and the 1985 with the apple printer. we forget how mind blowing that was. it was desktop publishing. that was kind of amazing. people used to buy ink by the barrel and publishing was hard. now, you can put it on -- you can put on your it on your desktop with software and point and click. it's high-quality professional stuff, and that is super exciting. those printers spoke a language. that language was the same spoken by other printers in the world. you really could upload and publish and that was kind of exciting. and then we did the same thing with a web and you can write code on your desktop and now you can push code out of the whole world and you could distribute as well and now we are doing the same thing with physical goods. now we have g-code and others, it will drive the biggest things in the world. rather than 3-d printing it, it will do the inverse. it i
