I love it when they're not afraid to show the mathematics!
pff, that's nothing
Good point and you are right 😊
Mathematics can explain science easily, So I love mathematics to :)
@@non-inertialobserver946 oh sure, those theories are nothing, pfft " im really smart I understand what i means and I can do more maf than all of u hehe im smart" stop being arrogant
@@chronicsnail6675 I was being sarcastic, don't get butthurt
Someday I'll understand what I just watched
lol soon
i like your optimism.
i will try too ..
It's not hard. Okay it's probably tremendously hard, but always remember that all these fancy symbols mostly just stand either for known constants or known formulas, there's nothing hidden there. All that needs to be known is what those formulas and constants mean/represent and how they interact together, all the rest is just pure math and logic.
Me too.
i like to thank this guy and all the mathematician and physicists for giving engineers the tools necessary to advance technology.
@@kriscurkovic9265 and stretch
@@kriscurkovic9265 Einstein... hasn't changed the world.. one bit? You're either too thick to understand the concepts he brought to the scientific community or you're ignorant of those concepts. I'd like to believe it's the latter and you're not actually that stupid.
You think they do this for your dumb technology to comfort your pathetic life. Nobody cares. They do it for understanding nature. Engineers however, are scumbags and think in terms of some paper. FK u all idiots.
@@briansanchez2322 he dum
I adore physics and math
That is a True Lie… detected. ;)
One day I will understand this. Well time to go relearn how to long divide...
Do you understand it finally all these years later?
I like it when people such as Rodger Penrose take the time to explain meanings of symbols in equations, regardless of your math skills it actually helps in understanding much of the written text as in his book," Shadows of the Mind ".
Explaining so non-mathmaticians can understand is fantastic and illustrates how truly knowledgable you are. Wish you could get NOVA to let you do a special on just this topic. A little history, how to understand it, and what does it mean moving forward.
Thanks Brian Greene, I feared that I would have to do a lot of work before Higgs Field stuff started making sense, but you explained it all much better than I had expected.
Brian Green's descriptions always makes me think i understand Maths, until the video is over and everything falls apart. Thank you Sir!
Wipes drool from chin.. I don't have a single fucking clue what I just watched lol. Happy to live in a world where other people have this gift though!
It's not a gift. Anyone can learn to think along these lines, given the opportunity and the motivation.
I have to disagree my friend. Not everyone has the mental capacity. No matter how hard I try I could never get this, and I'm an extremely motivated and curious person.. Everyone has their limitations.
michael e join the club.
michael e I was looking for a comment that I understood and agreed with and yours was the only one that I found. Now I shall take my blanky and rest a bit.
@@mdefp5168 I believe he was referencing Lie groups, and some of them are used to describe collections of continuous symmetries like the rotation of a sphere.
It's really not impossible for anyone to understand, there's just many layers of mathematics. Really the biggest gap is between modern physics and quantum mechanics. You could easily understand QM or general relativity in a year.
Wow, that actually helped me understand this a lot better. Symmetry and fractals are the most beautiful aspects of reality.
I always felt like reading physics books without equations with no different than reading a piece of literature and calling it history. Videos like this make everything fit into place and adds clarity to the science behind it as to why something is true. So thanks for this video, BG!
In the graphics, psi-bar doesn't have a bar over it.
Did they screw up that equation in the graphics? Where is the bar on top of psi?
LOL. I saw that too. Brian Greene needs to review after mograph is done.
I was curious why there was no bar either.
Yep. That's a typo
Those equations they're showing you are from quantum field theory, specifically, quantum electrodynamics. It's been a while, but the bar represents the complex conjugate of the psi (the wavefunction). I'm stating this because the "d" with the slash looks like a operator, on the regular wavefunction. Seconds later, when the show the two psis, I believe that's they're method of just stating the observable space of wavefunctions or the wavefunction squared.
andyiswonderful its a complex conjugate of a wave funtion
If think someone forgot to add the bar over the first psi ;)
The time has come to show equations more often, because most laypeople think we are only guessing around in physics and talk in pictures. And that is why many think popular books contain everything they need in order work on it themselves. They need to see the kind of complexity we are dealing with - the mathematics - so they can come to appreciate how deep we are going and how rigorous we are in our pursuit of the operations of the universe.
That's why I stopped watching Brian Greene and Tyson. Pointless documentaries where they NEVER go into detail, just rely on CG.
i wish we had teachers who could explain things like this back when we were at school.
Dear Kiddo, thanks for your question! It's such a pleasure to hear from someone who finally understands the science. Keep up the good work!
--Brian
Not in this case. Psi is a complex vector with 4 components, i.e. it consists of 4 complex numbers. Bar denotes the so-called Dirac conjugation which involves the transposition (row vector to column vector), the complex conjugation, and multiplication by a special matrix, usually called gamma_0. This matrix is one of the basis matrices which form a representation of the Clifford algebra. In quantum mechanics, simple complex conjugation is often denoted by the star, rather than by a bar.

Those of you who are interested in Geometry and Modern Physics I suggest you watch Atiyah's Lectures on RUclips.
There is one on Geometry and Physics but a very interesting one on 'What is a spinor?'
He obviously approaches the question from the perspective of a geometer but it is fascinating because one could offer a text book response; i.e. a section of a spin bundle blah....blah...or some variant of but Atiyah asks a more fundamental question; what is the geometry/topology behind such objects and maybe the answer will bring about a better understanding of this incredible marriage between modern physics and modern geometry.
I also recommend Lawson's etal Spin Geometry as well as Donaldson Kronheimer Geometry of 4 manifolds and if you can get a hold of( I believe Morgan) Seiberg Witten Equations!
Javed Singh is it the one from the Atiyah-Singer index theorem?
No and maybe yes! A general talk on Division Algebras over The Reals and Physics. I apologise I cannot recall the details;
real numbers= Electromagnetism
Complex numbers = Weak Nuc
Quartenions = Strong Nuc
Is it so that Octonions= Gravity??
The fact that these are the only ones comes from a proof in K Theory- see Husemoller
I think that's the jist.
Apologies for being vague
K Theory as in String Theory?
I got in here curious to hear something about the particle accelerator, and I got out astonished by how incredibly abstract and incomprehensible these people's jobs are.
Why did Brian Greene not check the symbols in the video? He would certainly have spotted the missing bar on the complex conjugate of psi.
The missing bar is really irritating
the bar does not exactly mean complex conjugation though, just saying
im a physics graduate student.. nd i want him as my professor😢😢😢😢
who doesn't
do you know whats the mass from H to the 118 elements? if not a will tell you its 17126.594 if you divide it/3.1416 = 5451.5514/ 6.472(1.618 x 4)= 842.3287/3.1416 =268.12092/89.28 = 3.0031465 - Know if tou add gravity of the eight planets of the disc you get 77.86/ks sq. and adding 274 of suns gravity you get to 351.86m/ks sq. and 351.86/31416 = 89.28 x 3 = 267.84 - 268.12092 = 0.28092
the universe is metric see 149.6 millions of kilometer to get to earth times 210 = 31416.
Yay for Brian Greene! I like it that he gives us all the math details.
says "psi bar", but don't see a bar above psi in graphic.
The Psi bar is the greek letter Psi with a line over it-it is the complex conjugate of Psil
eastwestcoastkid yes I know. But at time 1:30 he says "The new mathematical term...has a psi bar and a psi in it" but the graphic doesn't have a bar above the first psi. I've checked with wikipedia, and it seems this video's graphic is wrong there.
I think that the bar is so close that it looks like it is not there-at any rate I think we both know what he means by the phipsipsi-bar term.. That said that it might be good to revise the graphic.
Also suggests the idea that mass is associated with the Higgs field.
M always great fan of Mr.Green. (Y)
kind of good on talking weed science - he hits the highest on emotion that make you stay.
there is a fairly serious error in the equations displayed - he is saying 'psi-bar' but they are only displaying 'psi.' kind of surprising since mathematics are the subject of the video
Galen T actually physics is the subject of this video, not mathematics
moust off math is wrong we are a rainbow with 8 colors been the 8th the black or planetary
So, adding the mass term and the Higgs field term completes the equation and preserves the symmetry while doing it.
Thank you Brian that Is a beautiful and elegant description of everything, peace and love, Doug :).
For those of you saying 'I don't get it', its certainly not simple but its for sure doable. If you really want to learn it, you can.
He's saying "psi bar psi" but the graphic doesn't show psi bar psi; it shows psi psi. What's up with that? Also, it's just addition, subtraction, and multiplication with variables. The operations are not difficult at all. Most folks should be totally comfortable with distributive property or order of operations with simple arithmetic even if the variables are unknown.
YES ! Math should be included when great ideas are explained !!
-> The Higgs field is spread throughout the universe and it's given the mass of any particle to the interaction with Higgs filed
my question is - > How to Major Mass of New Born Baby in nasa Space Station (in zero gravity a space) ?
-> how to scientist find the mass of any material in a Space Station ?
This is an awesome way to explain it, but is there a 20 minute version of this where he takes the time to explain each term? It's fascinating to watch a physicist do this, and I would love to see more!
I didn't understand a single second of this video, yet I wanted it to go on for another 10 minutes
Brian Greene is brilliant. He writes very good books as well.
No, you just don't understand the terms that you're looking at. Since the wave function is multiplied by itself in all terms of the equation (which represents the 4-space position of the particle and it's orientation), certain reflections and rotations will cancel out and the equation remains consistent.
Thank you very much Brian Greene
Need more of this
Brian is a national treasure
So it's like algebra, except way more complicated?
***** I can only say how horribly funny that was.....
@@drmoroe Area 52 USA mathematical expressed dimensions dim 5682
Fuv is a tensor of rank 2 . There FuvF^uv is simply dot product.. that much I can understand.
yeah i dont get it , but i think someday i will make it goal to understand some of the math behind this , just for fun, i might not succeed but i will try
+Du Duu Just remember that learning math is sort of like learning a foreign language. It only seems too complex to understand because you don't know what the symbols mean. Once you learn all the meanings in the "language", it's a lot easier to understand what you are looking at. I say this to encourage you to keep pursuing it, because understanding math equations isn't a matter of intelligence, it's just a matter of study.
Consider that the only reason I can't speak Chinese is because I don't understand their symbols, not because I'm not intelligent enough to understand it. All I would need to do is put in the time to memorize what all those crazy symbols mean and I could understand Chinese, and all you would need to do is put in the time to memorize what all those crazy math symbols mean and you would understand the equation. Keep at it! :)
Thanks mate.
every thing is easier to untherstand when you find the universe is a rainbow no matter how you see it and maybe god is light after all but not like Wheelers : with out matter or gravity.
Congratulations for your work, I am a big fan of yours, from Brazil
Mostly layers of light subatomic particles make the gaps between electrons shell and nucleus. Symmetry and the disturbance gives shape. Light has four sublight particles called higgs field particles. Higgs boson is a trapper for creating subatomic particles. Higher ev than light.
symmetry is a lot more intricate than "add another term pls"
i'm not sure, but i think psi is a complex number, psi bar is it conjugate.
Beautiful!
Forgot to put bar on top of psi bar ....
Real life is continuous variable and represents by numbers which are discrete rather continuous variable. Interesting!
Thanks for the lesson in college algerbra.
You have to understand and never forget along the way, that you gave rise to mathematical analysis, and not the other way around.
Brilliant video. The math will keep trolls away. 0 dislikes.
Hats off to scientists!!!
Those equations that you have written as a sequence is the best fit algorithm of the cosmos and easy explained. Because you can't represent a cosmos in a single equation I mean describing only one force or matter or creation and destruction but the shell after shell is easy and how they switch over the the higher dimension is also practical.
Just start with Planks particles and getting the layers unraveled.
At each layer what forces come into existence and what energy density is expected and how the higher level forces interact with lower level forces and what kind of matter you expect to see. And how those mass particles interact.
Wow, this is one of the most difficult concepts, and he gave a very good explanation in 3min! Now ready, exercise one, let's solve the standard model lagrangian. :O
I don't understand what kind of symmetry it is.
So, to summarize, the first equation brought up @ 1:35 tried to add mass to the equation but could not create symmetry because it included a fixed amount of mass to the particles thus breaking the symmetry to the final formula. the fixed amount of mass could not be symmetrical with the rest of the formula....however if you add the new equation @ 2:00 it introduces a constant value of mass (m in the term) without making the mistake of being a natural mass term. this allows mass to be given to the particles in the formula but without compromising symmetry. Im not claiming that this is correct this is just my thoughts on the video, so if anyone can correct me please help me out in understanding this!
This was actually super helpful.
I was polite enough to provide you with some argumentation for my position. If you are just going to be hostile and trying to insult people, i (and undoubtedly anyone who will read your comment) will consider this your admitting that you don't have anything to support your standpoint.
I'm going to have to watch this at least one more time - or two. Not today.
Is it just me or Ephi is meant to be orthogonal and invariant under the translation of the symmetry. All you have to do is remove the degenerate adjoint by relativistic correction.
hi brian. have questions. how can we visualize higgs boson particle as a massless particle traveling the z axis with a measurable speed?..as a vector for example? also how can we sure we observe a new boson particle with a mass of 125.3 +/- 0.6 GeV @ 4.9 of significance (very high to be a probability) and last question ...i assume that higgs bosson have some effect on string theory isn't?
What was the middle thing????
Thank you!
Why don't they reveal mathematics everytime. I think this is the single video on youtube which tell the math of any physical theory i have searched so far
Do they want to keep it super secret?
the math is super complicated....would take hours to explain .....and those type problems even simple ones takes months to solve....like uf i told you to count the blades of grass in your front lawn.....
Can we have a lecture on this?
Okay.
Oh yeah, makes total sense.
Thank you
Big fleas have little fleas and so on little fleas on them, guess each can can be trapped in a mirror symmetric black box... if it is all about identity elements the symmetry remains but part of the picture we are beginning to out grow or find a higher level again... You got good response so your popular writings are doing a service for science but I found this beautiful yet not that deep, the fabric of it all and all. I await a future book that will knock our socks off raise bar for us.
Thank Brian
The symbols should be an accurate abstract of the term it represents. If I were trying to be clever with the psi( n) = sine value for wave mechanics or Cian for QCD
awesome description..
I thought I was sober for weeks. Now I just got drunk after watching this video lol
So you guys added something to keep things going, right? Like oil in an engine, or what. Help me
I would have preferred more time explaining the complex parts of the equation rather than the 30 second explanation of symmetry...
Awesome.
Nice Answer !
not a clue what all those symbols are... except that F is force right?
i have no idea but its fun to watch
Closed caption, please!
How do you know?
I am of the understanding that, more than the Higgs giving mass to matter, it is the Strong Nuclear Force which does so with more ferocity.....(capitalized for your pleasure :) )
Is there the full video?
yes that's what he's saying. theoretical physics is all about predicting the mechanisms of nature through mathematical models. The equations that arise from these theories are testable/falsifyable. Einstein described the relation between mass and energy, and it turned out to be right. Same goes for Newton's, Dirac's, and countless others. So yes, the atomic bomb (or nuclear power) wouldn't be here without that equation.
rather the other way aroung the higgs is an emerging property of the string level of reality.the higgs works by taking the vibration and frequency on the string level. the higher something vibrates the more widespread it's probability is and thus it is less and weighs less. While the models we have today do explain some things they are quite off with reality.
OK so you're leveling the relative energies of space to the space and anti space (matter), very intriguing.
dark matter is just a term we use for the phenomenon that causes observable objects to move the way they do, yet can't explain yet.
dark energy is also just a term, in this case the term we use to describe the mysterious force that causes the expansion of the universe to accellerate.
So dark energy doesn't have to have mass at all. As for dark matter: we just don't know.
The only way you can understand what Brain just said is by passing a course in quantum field theory. If you haven't, then this explanation is basically gibberish.
Particle physicists are a little too attached to the concept of symmetry. Symmetries exist in physics, but the laws of nature are under no obligation to be symmetric. They're certainly under no obligation to be symmetric just because theoretical physicists love the idea of Noether's Theorem. For example, it was discovered in the 1950's that parity is not always conserved in weak decays. It was previously simply assumed that parity was a symmetry of the universe, because the theory was more "beautiful" that way.
Symmetry when needed and non-symmetrical for everything else is how physics rolls.
zer0dahero >
What gives you that idea?
All I'm saying is that string theorists are misapplying the principles of Noether and Hilbert in an effort to solve some of the problems of the Standard Model. This has led them to nutty ideas like 11 dimensions, and the existence of a multiverse. Without a shred of empirical evidence to back it up .... Guys like Greene think they're as brilliant as Dirac. They're not.
Steven Weinberg says it well: "I don’t want to discourage string theorists, but there’s just the possibility that maybe that isn’t the way the world is, that the world is much more like we’ve always known, that is, the Standard Model and General Relativity"
And Feynman:
"The first principle is that you must not fool yourself - and you are the easiest person to fool"
And: "We are not to tell nature what she’s gotta be. … She's always got better imagination than we have"
That's all I'm trying to say .... OK, zero?
zer0dahero
Ok, fair enough. Where is the evidence for strings?
zer0dahero After viewing this video again, I now realize that Greene doesn't mention strings. I haven't seen this one in a while He's only discussing Higgs. My bad.
The reason I was harping on strings is that Greene has been their #1 proponent over the last 15 years. I assumed he was shilling for them here, or to promote one of his books.
Well, symmetries = conservation laws, and conservation laws are ultimately what it all boils down to. Particle physicists DID have to forcefully abandon a symmetry that looked perfectly natural at least one - aka the CP symmetry in electroweak interaction. But though I don't know the standard model well enough to tell, from a glance I'd say that the symmetry that would get broken here if the Higgs field wasn't there would be related to the Lorentz invariance of the equation... and considering that the whole starting point of QFT was to make QM Lorentz invariant, that would be a pretty big forfeit! And since the Higgs was actually found it does look like holding onto this symmetry argument was the right hunch here.
what do you mean by psi bar psi?
Is Higgs Boson need new collider to produce more mathematics like this?
Dont you love it when they use simple math like simplifying factors to describe something so complex
I guess u should know abt tensors,commutative groups and bit of axioms of quantum mechanics to know what that equations means
I've heard string theory is about done - the super-symmetry particles did not show up as expected at CERN and a probe of Mercury's orbit showed no variation in the gravitational constant G as string theory would have predicted - so these two things together spell trouble for string theory - of course these could be just rumors...
It would be useful if he told me what the symbols mean and why that one symbol is m + H, As far as I know any of those symbols could be a lemon meringue pie.
I understood the math and I felt really smart for a second, then I realized it was just super easy.
Who else loves watching these kind of videos even though you don't understand the equations 😂😁😁
I understand it
You know the gravity waves that were discovered this year that have backed up the theory of inflation? How does anyone know these waves are not the products of super novas?
So higgs feild is the key to symmetry and assuming that prevails the cosmos does it give a clue on multi verse.
Does higgs feild is the creation of the spin of the universe.
Something like if you have any surface and it is spinning and if you give a spin of any matter on that it affects any other matter.
That initial energy when big bang was created and set the universe spinning.
