Benedict Marck Benedict Marck 6 years ago Professor Copeland, you're simply the personification of what/how a teacher really should be. 187 LiiMuRi LiiMuRi 10 years ago What I find especially amazing is how good questions you ask, Brady! It's a talent of it's own to know what to ask. 7 jimmyjazz240 jimmyjazz240 7 years ago I don't pretend to fully grasp what the Higgs field is, but Professor Ed really does explain things so that a layman can gain some limited understanding. 23 Mike Braithwaite Mike Braithwaite 10 years ago I could listen to Ed speak for hours. He speaks about things in such a clear way that even if you do not understand the terms, you understand the meaning. Also the way Roger just kind of rants about how difficult it all is to even begin to explain the Higgs is sobering! 2 Peter Trast Peter Trast 10 years ago Brilliant! Best explanation of Higgs I have heard to date, between the different professors. 2 Marvin Rock Marvin Rock 10 years ago I don't know how I missed this vid the first time around. I gotta say, I am getting a new appreciation for the difficult job Brady and the absolutely brilliant minds do when making these. I feel really blessed to be able to hear their input and interpretations of the subject matter at hand. One last observation: Brady, you are making videos of great historical significance here. How does that feel? skudzer1985 skudzer1985 8 years ago Damn Brady you have some amazing questions. I could never think of these questions in front of these great minds. 32 filszyp filszyp 9 years ago Thank you Brady for your awesome videos. Sure I can't understand everything but I still learn a lot. And of course thank you professors! :) 1 Pleiione Pleiione 10 years ago Excelent video, got my full attention for 50 minutes! Great questions asked and great answers given. Tkank you! I wish I have professors like that to teach me 1 Tyto Tyto 10 years ago This was a brilliant video and really helped my understanding on what the Higgs actually is, and does. Much more so than the edited down version. underdawg47 underdawg47 6 years ago That made me think of an interesting idea. Wonder if the entire universe was like an endless, motionless ocean of some semifluid with the constancy of Jello, and then suddenly an event happened causing a wave to ripple out in every direction in this space-time material. If mass is somehow some kind of standing wave propelled through this medium in the wave of the now moment, we could be like images of a movie projected upon a 3 D screen. Perhaps the Higgs Boson could be like the way water molecules give waves their shape, but the actual peaks could be what we actually perceive as mass, being that we supposedly live in a universe where everything is a wave. i suppose it would be hard for an actor on a movie projected onto a screen to actually observe the screen, if all you could detect was other waves such as yourself. because in the ocean, the individual little atoms don't travel along with the wave, it only contributes to the formation of the wave. 3 metadaptation metadaptation 10 years ago oh man, i love your intuition Brady! any other channel would have edited out some of this, but you were nice enough to give us a full 49 minutes, thank you! M S Islam M S Islam 3 years ago He can explain very simply and clearly...he has very deep understanding in theoretical physics.!! 1 PhilSentMe PhilSentMe 9 years ago My friend's son, a 3yo, once explained to me why birds fly in great detail. It had something to do with trees, colours, baby chipmunks, hopping up and down on one leg and spinning in a circle. These facts were so obvious to him and he was excited to share his knowledge. It was very amusing to listen to. I like being reminded of that. He's 4yo now, and more eager to listen and learn than to randomly make shit up. Still a very imaginative boy, but also smart. jeebersjumpincryst jeebersjumpincryst 10 years ago Brady, if Id seen this before the short version, I wouldve said there was no way it could be edited to anything shorter, but youve actually done a really really good job of it! Its also really good to have MrOldProf back! yay!!! Austin Duke Austin Duke 10 years ago This may be asking a bit much, but I for one would love to see piece looking at the higgs that gets into the core mathematics of. I recognize that the video risks a healthy chunk of viewers putting it off, but I think us maths savvy viewers would get a lot out of it, Thank you for the great work Brady and friends. We all appreciate it. teavea10 teavea10 10 years ago That was a massive video. Very good questions from Brady. Stuff like this boggles my mind. It seems like ultimate small scale reality is composed of a bunch of abstract mathematical entities interacting in abstract mathematical ways. It seems that "having substance" fades away at such scales. Red Pill Red Pill 4 years ago Whom ever is doing this interview really knows the questions to ask... great vid 8 Renshaw Renshaw 10 years ago All of these fellows are brilliant, engaging speakers. I've never watched a 49 minute video on YouTube before, and not only did I do that, but I enjoyed every second of it! akashashen akashashen 9 years ago Gravity, which is a force, is the attraction of masses, relative to their distances (inverse square law). Gravity is what happens AFTER a particle has mass. The Higgs boson is the energy exchanged between particles as we generally know them and the Higgs field. The Higgs field is a pervasive tensor, a fancy calculus term to mean it has value everywhere, but that value is just a value, and the interaction with the field is dependent on a second mechanism, hence "The Higgs Mechanism." CharLim ryanisflyboy ryanisflyboy 10 years ago @insomniac1893 It is a visual reference of the SMPTE time code. It shows (from the right) frames, seconds, minutes, hours. This looks like 24 frames per second (watch the frames counter as the seconds tick by). Since this is raw footage it has been included, partly to show time sequence changes and partly because it is easy and fast for the producer to export it that way. There are several important uses for time code such as cataloging footage and syncing edits. antonywilkins antonywilkins 10 years ago Fantastic video - best yet. Also the best explanation of the Higgs mechanism to the lay person I've heard skudzer1985 skudzer1985 8 years ago My life would be infinitely better if we could get more of these 40+ minute videos. akashashen akashashen 9 years ago The mechanism is the means by which a particle can interact with the Higgs field. More energy does not equate more interaction. For example, a proton is, subatomically speaking, a significant amount of energy; yet, its interaction with Higgs field is far less significant than that energy might suggest. For example, a top quark, a quark, mind you, something with less energy than the hadrons they make up (like protons), interacts as strongly with the Higgs field as a tungsten atom. miphisto55 miphisto55 10 years ago Thank you VERY very much Brady! I can't wait to watch this entire video :D! I just finished watching the shortened version and I've just made myself a nice hot cup of coffee so I can enjoy this video! Bas Bas 4 years ago Interesting what he said about the breaking of beautiful symmetry at earlier stages being necessary to move things forward. Reminds me of the Apollonian and Dionysian dichotomy in philosophy. 1 un2mensch un2mensch 10 years ago Excellent stuff, Señor Haran & all the physicists. I'm hoping to one day understand what influence interaction with the Higgs field has on mass/energy equivalence (E=mc²). Because when people talk about the Higgs field imparting mass, and when Ed says at 2:50 that particles were massless in the very early universe, surely that breaks this equivalence? Obviously there are different definitions for these terms that I don't know (and I know very little!) Martsen Martsen 10 years ago Not sure why I didn't see this until now, but a question I've had about the Higgs for a while: If it is many times more massive than a proton (apparently approx 125x, if the experiments prove statistically significant), how is it that it gives a proton a mass which is so much lower than itself? Cuboid Siren Cuboid Siren 9 years ago Actually, the particles get their mass by interacting with the Higgs Field, not the Higgs Boson. The boson is a virtual subatomic particle produced when particles collide against the Higgs Field with enough force. The reason why scientists are happy to have detected the boson is because this affirms the existence of the Higgs Field. UltimateSubZr0 UltimateSubZr0 8 years ago Now this is what I call extended. Good job. 2 Arik Arik 1 year ago Give more extended interviews, please!!! David David 9 years ago Consider that perturbations in the Higgs field results in a local energy field that manifests as gravity through mass. Then gravity is the (push) force that maintains mass. Gravity is a property of the Higgs field and not of matter per se. Gravity is then an interaction mediated by the Higgs boson. Hence this is a conceptual foundation for describing quantum gravity. Paul Singh Selhi Paul Singh Selhi 1 year ago The breaking of symmetry is absolutely vital for the creation of the universe we have today. Discord is the stuff of life not harmony. 2 Cindermellons Cindermellons 10 years ago So, am i thinking about this right - if we think about the universe as a massive CAKE - then the particles are like the water/egg, moving around freely and the Higgs Boson is the flour which binds everything up and gives it mass and hold it all together. Is that right? THANKS guys for giving your time to do these videos. I love them. Big fan. mceyekon mceyekon 10 years ago As most things in QED, this bosom is counterintuitive: particles need another particle to gain mass so that they can interract with eachother gravitationally. Well, the photon's mass is zero and it still interract with gravity: gravitational lensing! Could someone explain this appearent paradox? Marcos Alcazar mendoza Marcos Alcazar mendoza 5 years ago (edited) I can believe that there are physicists British professors from Nottingham using my Mexican sombrero as an illustration of a fundamental physics science as Higgs field is. it is just absolutely amazing!!! I wish I could have a professor like Prof. Copeland is awesome explaining things. Greetings from New Mexico :D Michael Jackson Michael Jackson 9 years ago Exactly. I have thought the same thing. I've also used the same concept to ask another question. String theory has been becoming more & more popular. People talk about it explaining so much about the universe. Well, inside atoms we have a nucleus. Inside the nucleus we have quarks, which scientists now say are made up of strings (either that or they're actually strings...I'm not a physicist). Well, what are the strings made up of? Let's imagine we get smaller & smaller, we can ALWAYS divide by 2 veggiet2009 veggiet2009 6 years ago I really like listening to these "unedited" videos 34 Onder Ozenc Onder Ozenc 1 year ago (edited) Higgs fields are formed during the energy-matter transformation under the strain of threshold energy. It is a bremstahlung process. jdawghatesyou jdawghatesyou 10 years ago The best way I have heard it described was the Higgs Field is like a tank of water, and the Higgs Bosons are the molecules of water. Depending on the particle moving through said tank of water depends on how much it interacts with the field. I fish interects very little so it has a low mass, and a fat man interacts heavily with the water so he has a large mass. tahir tahir 9 years ago The best video on the subject for a common person like me ... Thank u. Fuji Water Productions Fuji Water Productions 9 years ago All i could think of during this interview was of how a mass effect relay works. it reduces mass of an object and then shoots it across the galaxy to another mass relay akashashen akashashen 9 years ago Forces involve transition, as a result, there are only four forces recognized by the Standard Model: The Strong Force, the effect varies on quarks, reducing its effect after they get close enough (asymptotic freedom); The Weak Force, which can exchange and disrupt the structure of quarks; Electro-Magnetic Force, which uses charges to repel or attract charged particles. Gravity, and it is very importanty, Gravity...will be covered after the character limit. Krokonil Krokonil 10 years ago @Brady, A question, please, if it is possible ask some of the scientist at Nottingham. We know that all things with mass get more massive as they increase their speed and as close to the speed of light they get their mass incises more and more. That's why things with mass cannot move at the speed of light – their masses will become infinite. How this can be explained in the Higgs field? Is it moving faster means stronger interactions with the Higgs field and acquiring more and more mass? GabrielTranceSanchez GabrielTranceSanchez 9 years ago I know it's not simple. I've read and watched. For the most part, everything matches up and is all good. There's just some things that don't follow the rules or make sense. There has to be a better way to approach them than to just use our old/current ways. Yoda (Ghost) Yoda (Ghost) 8 years ago so if when the universe cools and the higgs field becomes nonzero for some particles, does that mean that other particles (eg. photons) will become massive? Michael Jackson Michael Jackson 9 years ago You sound like a logical individual & I LOVE rational minds. I would actually enjoying having a back & forth with you on this if you want but I'm starting to get annoyed with these 500-character limits because I find myself not being able to fully convey my thoughts & ideas. Based on your previous response I'm guessing that you're having the same trouble. If you'd like, we could have a debate on this via the private messages on YouTube. Let me know, if you prefer to talk here, I'll respond here. Peter Trast Peter Trast 10 years ago Is it remotely possible that the 21 grams of weight that some claim to be lost at death is related to Higgs and the gift of mass being reduced slightly? And how many more collisions before Higgs is abandoned and the Standard Model dies? We already know that E may not equal MC squared now that neutrinos appear to be faster than light. How might these be related? Lightful Lightful 9 years ago I tried working out what he said around 12:40. He said that the higgs would be ~125x the mass of a proton, and you'd need the e=mc^2 equivalent energy to create the mass. Well I worked out the energy to be 2.25x10^-8... Did I do some wrong calculation? Because that's really low energy to say they're slamming proton together just short of the speed of light and barely getting anything... Samiena Amien Samiena Amien 5 months ago Brian Cox is great at the big picture, and this guy with his quiet charisma is brilliant at explaining the minutiae. Wow.... Tony Mach Tony Mach 10 years ago Now Roger Bowley is a true scientist! I have the deepest respect for people who clearly say what they do NOT understand completely. Such a nice contrast to the storytelling braggarts that populate the media. Sandy McDonald Sandy McDonald 6 years ago From 35 minutes is an excellent explanation of the importance of blue sky research. Mohammad Rashid Mokhtar Mohammad Rashid Mokhtar 9 years ago How come Mr. Higgs can figure out the "thing" 50 years ago without spending billions, unlike these current scientists. Mickeyislowd Mickeyislowd 4 years ago I wish all sixty Symbols were longer like this one. 6 mins just isn't enough and just as I'm starting to enjoy it's finished. Tom Heal Tom Heal 9 years ago The mass required to completely turn light around is that of a black hole, so for this to be true every part of our own galaxy would have to weigh as much as a black hole. It's a neat idea but extremely unlikely This can also be disproven based on the fact that non symmetrical galaxies have been found Kev Kev 10 years ago never have I learned so much, yet felt so far from actually understanding .-. I thought watching the entire video would help lol, only left me with more questions 2 rightwraith rightwraith 9 years ago I'm not a physicist, but as far as I understand it; the massive particles have mass because they somehow interact with the Higgs field that pervades every place in the universe. The Higgs boson itself results from certain fluctuations in that field. It requires a huge amount of energy to fluctuate the Higgs field enough to actually create a Higgs boson. The Higgle boson itself interacts with the Higgs field in the same way that other particles do, giving it a mass. chromosome24 chromosome24 10 years ago @mceyekon a photon has zero inertial mass but its energy still contributes to a gravitational interaction. I remember there being research done at the University of Washington to measure differences, if any, between inertial mass and gravitational mass. ricktb ricktb 9 years ago so basically if there was only one large source of gravity in the entire universe, and a single photon of light flew past, it would change direction by some degrees and continue on a straight path, or would it arc in a parabola much like a comets path... oh you know i have to rethink my theory you made a good point especially since light always goes at light speed. Julian Gonzalez Julian Gonzalez 7 years ago One of my favorite professors 1 Erick Erick 9 years ago does this mean that when they try to detect Higgs bosons from collisions, they're creating massless particles (photons or something) or are they just exciting the field with the colliding masses? Alexandros Metallinos Alexandros Metallinos 4 years ago Thank you very much for these interviews. Cush Cush 1 year ago There should be a video about Nambu–Goldstone bosons and the relation to the Higgs field and bosons. 2 chris4072511 chris4072511 10 years ago If it wasn't for the bits with the hat I would be thinking that I had a vague grasp of it. Despite my inability to really get it, absolutely fascinating stuff. irob160614 irob160614 10 years ago have any theoretical physicist developed an explanation as to why some bosons have mass while photons dont or are any currently working on the problem? also do they know what it is about a particular particle that determines the strength of its interaction with the higgs field? Don Carlo di Vargas Don Carlo di Vargas 1 year ago What about building a higgs-particle vacuum cleaner to collect those small particles? If we empty an object for its higgs-particles it turns out to be weightless? Ty Ty 10 years ago So, my question then would be. If Higgs Boson particles give all other particles mass, why do Higgs Bosons have mass? (What would be giving the Higgs mass?) Tomasz Adamczyk Tomasz Adamczyk 1 year ago Could virtual particles break the symmetry? D D 9 years ago Gravity doesn't bend light back around like that though. It bends it like a pair of glasses bends light. It doesn't make a loop, it just bends it a little. We can look into different parts of the sky and see different galaxies at different distances, with different characteristics. Your theory may sound cool, but it is wrong. wtfpwnz0red wtfpwnz0red 1 year ago 0:15 merely seconds into the interview and he's already discussing human instrumentality jeebersjumpincryst jeebersjumpincryst 10 years ago i called in sick to work, just to watch this. and Im never sick. THANKYOU THANKYOU for all 49 mins 38 secs of this vid. this is what heaven would be like if there was one! BlokenArrow BlokenArrow 10 years ago Isn't it more likely the "particle" associated with the Higgs field is the graviton? John Krolikowski Jr John Krolikowski Jr 9 years ago this is greatness. sfsoma sfsoma 10 years ago Brady has learned to ask the most brill questions 35:11 David David 9 years ago Have you done any videos on String Theory and a Theory of Everthing? Would be interested in watching that ! chris4072511 chris4072511 10 years ago @Krokonil I'm not a scientist but I think that the increase in mass at relativistic speeds is just a consequence of regular time and space dilation in Relativity, regardless of the mechanism that actually makes the mass. 8nwidth 8nwidth 10 years ago Prof.Copeland is always on the beat like in his Police Days! :) Circadian Circadian 10 years ago So if everything was massless, does that mean things like protons had no mass, or that they didn't exist yet? Michal Klein Michal Klein 9 years ago I just found out that you cut those videos. Please upload extended versions of all of them. This is so much more fun. Best spent friday evening :)) 1 ricktb ricktb 9 years ago yeah you can divide by two and strings theory is about the smallest so far i think. I guess science is just trying to find the smallest structure out there that defines everything, and at some point you get to the smallest waveform or frequency or string and then theres nothing smaller but if you think about waves you can have a large low frequency wave mixed with small high frequency wave in the same wave form so small or large its all part of the same wave form that is eveyrything we know sfsoma sfsoma 10 years ago Brady has learned to ask the most brill questions 35:11 apburner1 apburner1 9 years ago Well.... gravity doesn't really bend light. Gravity distorts space and the light is traveling straight through space including the distortion. If you "unbent" the space you would see the path of the light is absolutely straight. KegPatcha KegPatcha 9 years ago I want Sheldon Cooper to explain to me physics: "It was a warm summer evening around 600 b.C...." 1 B D B D 10 years ago
