a proton and neutron. i'm going to use the mathematical symmetry to explain why these two are so similar. he called it as you to read then we won't go where it went from there, but that section was wrong. that was taking mathematics that makes a lot of sense in your mind as a mathematician but has nothing to do with the real world and the sense of the protons and electrons. they look similar because of nature the mass of small. one of them is a lot heavier than the other in absolute terms, but we compare it to the math of the two. then you think they are really very similar. into century. of course you and i know that he went later. he did all kinds of things. the mathematics came back, but at that moment what you have is mathematics. yuri powerful and absolutely useless. i rest my case. [laughter] >> but it is a case that i agree with. what i would say is mathematics opens up the realm of possibility. thank you very much. and what the art of physics is, the art of physics is being able to sniff out which

well, the collider slams protons against protons at fantastically high speeds. and the math shows that in some of those collisions if there's enough energy, if they're moving fast enough, when the protons collide, they can create some debris that will get ejected off of our universe, off of our slice of bread. how would we know that? well, the debris would take away some energy with it. that means there'd be less energy left for our detectors to measure after the collision than before. there'd be some missing energy. people are looking for these missing energy signatures, and if energy's missing in the way that the math suggested it should be, this would be interesting evidence that this brane picture is correct suggesting there might be other -- >> have you been depressed recently? >> why do you ask? >> was you know that the lhc hasn't found something, so maybe they'll find it, but right now as a lot of people may have heard, the results are negative on that. and they're also negative on something else which i want to -- >> let me just respond to that too. you

. >> medications are very successful at controlling acid, but some called proton pump inhibitors haveeen linked to serious side effects such as wrist fractures, infection, osteoporosis and low magnesium. >> we are concerned about this and we continue to monitor the data as it comes in. >> gastroentrologist bob edomad says some sufferers are turning to a new procedure called tiff. >> about 80% of patients are finding complete symptom relief using this technique. roughly the same number of getting off their proton pump inhibitors. >> reporter: a tube-like device is inserted through the mouth into the esophagus as seen in this video provided by the company that makes the device. tightens the lower esophageal sphincter, creating a more effective barrier against acid. >> this is the least invasive so far of finding a way of repairing that valve. >> reporter: it requires an overnight hospital stay and, according to the doctor, about two to three weeks of recovery. >> the recovery was a little longer than i anticipated. >> reporter: he had the procedure in january. after suffering medication

together with united states ukraine russia and kazakhstan so then it will stay there forever the proton launch pad will be used until i'm terrified causes all five tests in the north which means at least ten launches and by tareq passes flight test in the south that will take almost chain years that's all three complexes will function for at least another ten years but they will be financed mainly by private investors rather than from the state budget. like a crew space center or is it a good example of international space cooperation. yes of course but only as far as carrier rockets are concerned i will the first to use take out from. european countries or recently announced it won't happen before august or even september first they're going to launch two galileo spacecraft for their navigation system and they won't be manufactured before august or september but construction works the crew have been finished. well today russia is an indisputable leader in space launches but also other countries are catching up what should russia do to keep its positions on the market. you know we const

well we have all these subatomic particles that we get by smashing atoms we smash apart protons we get quarks they get powers of subatomic particles and so we have a jigsaw puzzle this one piece missing in this case our puzzle and that's the higgs goes on that we hope to find with the large hadron collider we see string theory says that this jigsaw puzzle of particles is nothing but the lowest octave there's a higher octave the next octave of the string is called dark matter and dark matter we fake makes up most of the universe dark matter we think is ten times more plentiful than ordinary matter so every high school chemistry textbook is wrong every textbook says the universe is made out of adam's period end of story that's what the universe is made out of atoms we know realize that's wrong only four percent of the universe is made of atoms twenty three percent is made out of an invisible substance called dark matter which holds the galaxy together and invisible form of batter and beyond that seventy three percent of the universe is dark energy the energy of the big bang the energy th
