Nice Video! A tiny mistake in one of the animations though: the annihilation of electrons and positrons produces TWO gamma photons (of 511keV each) in opposite directions. That's how we are able to create actual images in Positron Emission Tomography: we can paint a line between two photons detected at the same time and then overlay millions of those lines to form something similar to a "heat map".
@@ArvinAsh there is also a mistake at (9:32 ) . The h in the uncertainty formula written there is not planck constant that's [h dirac]. And h dirac = h(planck constant)/2pi. BTW...your explanations are too good.
Thank you! It wasn't until I saw the visualization here of the electron constantly switching its handedness from left to right due to its interaction with the Higgs field that I finally understood how the Higgs field gives a particle mass. As you explained, the rate at which a particle switches from left to right creates a certain amount of energy and that energy is where the particle's mass comes from.
Watch Lenny Susskinds' lecture about Higgs. It digs much deeper into this topic. Maybe it's confusing at the start because you don't see "higgsiness" there but at the end it all comes together. It's "Demystifying higgs boson with Leaonard Susskind". I tend to rewatch this lecturefrom time to time to jog my memory on this topic.
Please help me understand. If the oscillation of the electrons interacting with the higgs field produces energy and thus mass, then where did the original energy come from that allowed the elections to oscillate in the first place???
Dr. Ash, thank you! This video clearly explained several phenomena that had previously left my head aching -- how the Higgs field confers mass, why neutrinos don't interact with most matter, why gamma rays are very high energy photons, what flavors are in quantum contexts.
Neutrinos are Siamese twins who initially existed separately inside quarks creating fields from particles and steered fields in their crazy twisted way of life. When the twins were able to reach out and grab hands inside quarks they decided to conjoin and go on they fairy-wheel life shaking their own hands as they journey the cosmos searching for new experiences.
This is amazing. These videos uncover so many unanswered questions that I couldn't find anywhere else. For example, the only answer to how the Higgs field gives particles mass I've found was always "it drags particles" or analogies with crowded places. Not once have I heard a connection with chirality. Now I need more! Keep up the fantastic work!
Thank you for explaining how the Higgs field gives the electron it's mass. I have been looking for a clear, simple, and un silly-fied explanation for a long time. Love your videos. Well thought out and very beautiful. This was an even more clear explanation that Leo Suskind have.
Omg, that was brilliant Arvin!! I learnt BRAND NEW THINGS in that 12 minute video that I didn't know before. Like this idea of the "missing mass"; I didn't realise that it had been established that it wasn't the higgs field that gave neutrinos their mass. That is so intriguing. I must now go back and watch some of your other recent videos to catch up!! Thank you!
Arvin, I have watched this video several times. I have also watched 3 other neutrino explanations. Your video a a good balance of clear explanation and desnsity of information. Therefore it is a pleasant task to rewatch your work, you don't waste many words (except your necessary sponsor promotion).
Your videos make me want to become a particle physicist. Or at least keep learning all I can about particle physics. Please keep making these videos so I can continue to learn!!
Great video Dr. Ash! All info are correct and to the point, while precisely and clearly delivered without ambiguity. My compliments... Greetings, Anthony
Again this neutrino from Lima, dear Arvin. Thank you for your CLARITY & for sharing your BEING! Keep on showering us with your neutrinos! My love to you.
So, if I got it correctly, neutrinos are created in a process that is essential to our existence; however, as far as we know, neutrinos themselves seems pretty useless 😅 Hopefully we will learn more about these particles! Loved the video and the explanation about the Higgs mechanism!
Hi, first thank you very much for your great work. I would like to know if it'll be possible to do a video about the Kaluza-Klein theory ? It will be great to understand it's implication, how gravity and electromagnetism are viewed to be bind, what all of it means etc. Thank again, stay strong !
Awesome video Arvin. I think it would have been great to mention the DUNE project being built by Fermilab which will explore the neutrino oscillation phenomenon. Maybe this could have lead to a collaboration video with Dr. Don Lincoln who hosts the Fermilab UA-cam channel. Again, awesome video. Thanks again.
I live near Fermilab and they have days where they allow the public to come in there. They do presentations, explaining the work they do there, and afterward you can have snacks and talk to scientists. It’s great, I’ve done it several times. One of the presentations I sat in was about the neutrino detector they’re building.
Awesome video Arvin. What about neutrinos' interaction through gravity? If it has mass and produced in prodigious quantities it should have a large gravitational effect should it not? It should manifest right? Many thanks
They have so little mass, that even the large numbers don't amount to much. All the neutrinos in the universe amount to, at most, 1% of the energy of the universe.
Great Video. I was wondering what happens to all these neutrinos? If they are produced through beta decay, then is the total volume and mass of neutrinos in the universe increasing or are they consumed through some other process? Thanks again for making these. I truly enjoy them.
All the matter existing in this universe is decaying with time sir.. If the entropy of the universe keeps rising (which we don't know anything about yet), then we will be left with nothing but pure energy.. Even the neutrinos are destined to decay one day..
Definitely a great explanation of why we should be glad they exist. Didn't really go back to more information on the imaging discussed at the beginning, though. That was a letdown, I must say. 😕
Wow, that cleared up half-a-dozen questions I've had for years. You are one excellent teacher! Quite an enjoyable / inspirational program. I attended UCI and remember asking Frederick Reines if the neutrino discovery was inferred or an isolated event (like what we see at CERN with the Higgs field). He wasn't too happy with my question!
More like a Feather than a Cat! Neutrinos Are Best described as "Cosmic Fluff" but, They're so Ghostly it makes me wonder if maybe, Ghosts might actually be something Real! Quantum Physics Is Just plain Bizarre! This is the first Science Discussion that's Ever helped me to Think of These Things as something Tangible!
That bit about how the Higgs gives mass is mind blowing, what a strange reality this is, and the fact that some species of eukaryote from earth can create large scale symbolic abstractions of the very fundamentals of the reality which gave rise to them is just a miracle!
Great video as always….!!!❤But basically for me.. What is always most curious about is what the opposite properties of neutrinos and antineutrinos are…. Would you please let me know it?
Thanks Arvin for taking us to the very edges of modern physics every time. How else would I have known that the mass of a neutrino is an ongoing mystery. By the way I think I have some evidence. I am unable to shed the last 5 kilo off my body to reach the target weight. Been trying for years now. I thought it was pastries. But dang! now I know its the neutrinos :D
Great topic , thank you Arvin , been reading up on my neutrino knowledge past few months .... Imagine the clean energy if they could be captured like photons.
I remember Star Trek TNG Geordi's visor was capable of detecting neutrinos 😳🖖🤨🤓 The problem with Higgs mechanism is that explaining it in layman's terms is always incomplete of course. Anyways, the part about changing the electrons is a good idea with your animated graphics. I remember Riemann surfaces on books, phase space with top view, spirals 🥺 and now there are some great 3D art just by plotting those surfaces in, well, 3D
Without Neutrinos being momentarily trapped within a Supernova explosion adding their energy to the outward explosion life would have never started in the Universe
Reminds me of my grad-school days. Elementary particle physicists have a hard time saying, "I haven't got a clue." Or even, "Something is missing." Colors and Flavors always drove me nuts, searching for certainty in their uncertainty principles. I still don't understand what they mean.
They symbolize some types of interactions between the particles, that have no equivalent at our scale. It's not a matter of "not understanding what is happening, so let's just give it a fancy name". It's a matter of observing that some particles interact in some way, that can be modelized mathematically as a property of the particle following some precise rule. However, there is no object in the macroscopic world with such property, so we just put on it a name to differenciate the state that the particle can take -like we make up a name for any new thing we discover. We choose "color" for the strong force interaction because mathematically it's similar to how color additivity works, but that's all there is to it. And "flavor" because, well, they're just different types of the same things, so why not name it like that. The problem here is always the same : for an intuitive understanding of something, we need to borrow some similarity with something we already know of. We use analogies. However what happens at this scale is so strange, so different from what we are used to observe at the macroscopic scale, that sometimes no analogy can really help. But this doesn't mean we don't understand what's going on, in the sense that we are able to precisely describe, and predict, how these particles interact. And for a scientific theory, that's all that really matters.
@@theslay66 I've yet to see a coherent description of color and flavor. And gluon properties are one of the messiest ideas yet. How elementary particles undergo fluctuations in these properties is not well described at all. And because of that, they are not yet well understood. The properties of elementary particles are not at all elementary. Something gigantic is missing from this sub-nuclear story.
@@jamesraymond1158 I do molecular biology now. Got my PhD in both subjects. Solid state nuclear magnetic resonance of proteins, looking at the coupling between thermal stability and molecular dynamics. Now a huge range of things from DNA microarrays to new theories of enzyme kinetics to inflammation in cell cultures. I love physics. But saw my brightest friends graduate with PhDs in elementary particles and in general relativity and end up pumping gas and waiting tables. So I knew I had to do something else.
@@Earwaxfire909 But it works the same way as the electric charge, or mass. In what way do you have any coherent explanation for these properties ? The only difference is that they manifest at the macroscopic level, so you can somehow think you have a clear view of what they are. But when you try to examine what they really are at the quantum scale, it's no more or less alien than color or flavor. They all are interactions with some kind of fields. And what are fields ? Heck, what is space-time ? Nothing more than mathematical constructs we use to describe how reality works. I'm not saying that the theory is perfect, and that we're not missing something there. We obviously are. But it seems to me you're thinking so for the wrong reasons.
Thank you ! How was the maximum value of each mass (each neutrino type) measured / calculated? Is it more difficult to measure/ detect a muon or tau neutrino, since muons and tau have shorter lifetimes than electrons? If you get the chance and the time, could you, please, talk about the different types of neutrino detectors, and detection techniques.
google for K.A.T.R.I.N. experiment. They are measuring the energy of the electrons coming from beta decays. They know the exact total energy from this process. Interesting are the high energy electrons. The remaining energy is the mass and kinetic energy of the neutrino. So they can set an upper limit for the neutrino mass.
Thank you for this wonderful video. I never understood the science of the Nutrino. After this video I now have a clearer understanding. Again, Thanks !!! 🤯🤯🤯
The eggheads are getting above their station when they arrogantly dismiss this particle as useless. They appear useless because they don't understand and might never mentally grasp the part they play in the grand scheme of the cosmos
Isn't it interesting that in the agnostic field of particle physics we still ask ourselves questions like what the purpose of neutrinos are, defaulting to a mindset of intelligent design 🤷♂️
The answer you are looking for is quite obvious. The neutrino Must exist or else conservation of momentum fails in the case of beta emissions. The neutrino patches this hole. Without neutrinos the standard model is crap. There, now you understand the purpose of the neutrino.
Thank you so much for making this professional video introducing neutrino and the relevant information. It's so exciting for an incoming physics senior student!
Thank you Mr Ash! You really expanded my knowledge on how particles gain mass in a Higgs field and those graphics were brilliant! I just wish you and other science educators a lot of patience and persistence in making such videos. And since we really live in interesting times, i hope we will see many more videos like this one.
Arvin, I don't know what I'm talking about and I'm half remembering something. I seem to remember they have a neutrino trap many metres underground in an old mine in Victoria and I seem to remember that they rarely detect a neutrino. How did you take a 'photo' of the Sun's neutrinos looking down through the Earth that you show right at the start? :)
Sir you are great explainer of difficult concepts with due respect i want to point out a mistake or typo error @9:30 to 9:45 where increasing uncertainties are regarded as more precise .
Yes, there are many wierd issues discussed here. But there is wierder matter concerning this topic; inside every atomic nucleus there is a field called ''benign'' field which is responsible for control of any decay within the atom. Like in Beta decay the weak force is responsible for it but not for the control of it, so benign field is like an injector or a gate controling the amount of energy being dissipated in decay.
at 7:07 by the time a gamma ray makes it out of the core, it turns into visible light particles. how so? is this the compton scattering? or how can a single gamma ray turn to 10s of thousand visible light particles, this seems to violates angular momentum conservation. at 13:12 BUT WHY undergoes beta- decay AGAIN when beta+ decay is extremely hard to be? one thing for sure, there must be the same number of beta+ and beta- or the sun wouldnt be charge neutral
Good great video is blessing for social media users . Ash is very specified on supernovae .He is like a good teacher removed the dust and Ash from standard model table.. He also went beyond to Higgs mechanism to put the mystery of neutrino and generation. Though neutrinos are charge les handless unlike electron's family. Thank you they are every where.
Excellent! The complex topic is distilled into very understandable concepts and in a seemingly effortless manner, which is a testament to the teacher’s skill. Such clear, concise educational videos don’t happen by accident - there is a master at work here! 👍
Wait, neutrinos can change flavors because they move slower than the speed of light. Thus, time passes for them. But if in the perspective of photons, time doesn't exist, how they change wavelength. I know the change of neutrinos is more of a mass transformation, but the photons frequency is more of an energy transformation, from the momentum. But mass and energy as we know are linked
Also your kind of socratic style of rhetorical questioning structure feels natural, as students and teachers interactions in the classroom. At least this is what I am accustomed to.
When I learnt about neutrinos at uni, I kind of pictured them as little tiny particles of energy converted into mass in it's most neutral form. It helps visualise it and that's how I understand things.
I would love to hear your take on how it is we can know right-handed neutrinos don't exist. As far as I understand, neutrinos only interact via the weak force. Only left handed particles and right handed antiparticles carry isospin and participate in weak interactions. Assuming some mechanism, like Higgs, allows neutrinos to change chirality, it seems perfectly reasonable that right handed neutrinos could both exist and be for all practical purposes unobservable.
Nice Video! A tiny mistake in one of the animations though: the annihilation of electrons and positrons produces TWO gamma photons (of 511keV each) in opposite directions.

Thank you - that was incredible-
hard enough to understand or visualize-
but you made it great-
Another fine video, well illustrated.
Fantastic topic! I've been wondering what it's purpose is for such a long time! Thanks for your content!
Thank you Mr Ash!
You really expanded my knowledge on how particles gain mass in a Higgs field and those graphics were brilliant!
I just wish you and other science educators a lot of patience and persistence in making such videos.
And since we really live in interesting times, i hope we will see many more videos like this one.
Arvin, I don't know what I'm talking about and I'm half remembering something. I seem to remember they have a neutrino trap many metres underground in an old mine in Victoria and I seem to remember that they rarely detect a neutrino. How did you take a 'photo' of the Sun's neutrinos looking down through the Earth that you show right at the start? :)
There are better detectors now. The photo was taken over many months and the interactions were amplified.
Awesome video Arvin! please keep up your amazing work
We are with you Arvin. Amazing content
I love your way to explain difficult things. Thank you very much.
Sir you are great explainer of difficult concepts with due respect i want to point out a mistake or typo error @9:30 to 9:45 where increasing uncertainties are regarded as more precise .
Well.. your information so valuable and well presented. Congrats.
Beautiful, lucid exposition. Thank you!
One of your best videos, Arvin!
Thank you Arvin, for making video on Neutrinos 😊
Excellent explanation! It really clarified many things to me! I had some idea of these questions, but now I understand much better.
Superb explanation of what gives the energy due to Higgs field
Yes, there are many wierd issues discussed here. But there is wierder matter concerning this topic; inside every atomic nucleus there is a field called ''benign'' field which is responsible for control of any decay within the atom. Like in Beta decay the weak force is responsible for it but not for the control of it, so benign field is like an injector or a gate controling the amount of energy being dissipated in decay.
at 7:07 by the time a gamma ray makes it out of the core, it turns into visible light particles. how so? is this the compton scattering? or how can a single gamma ray turn to 10s of thousand visible light particles, this seems to violates angular momentum conservation.
at 13:12 BUT WHY undergoes beta- decay AGAIN when beta+ decay is extremely hard to be? one thing for sure, there must be the same number of beta+ and beta- or the sun wouldnt be charge neutral
I believe that type II core-collapse supernovae would stall without the massive neutrino flux which completes the unbinding of the star.
Truly appreciated video(s) from both a scientific and informative perspective. I thank you!
This one is a banger. Well done sir!
Good great video is blessing for social media users .
Ash is very specified on supernovae .He is like a good teacher removed the dust and Ash from standard model table..
He also went beyond to Higgs mechanism to put the mystery of neutrino and generation. Though neutrinos are charge les handless unlike electron's family.
Thank you they are every where.
Always a pleasure, thanks, and thanks those behind many helpful coments.
It would seem the smallest particles make the biggest impact. Great explanation of neutrinos, thanks Arvin . : )
Wow, this video was awesome!!! Please keep this up, GREAT WORK!!!
Excellent! The complex topic is distilled into very understandable concepts and in a seemingly effortless manner, which is a testament to the teacher’s skill. Such clear, concise educational videos don’t happen by accident - there is a master at work here! 👍
Many thanks! Glad you enjoy these videos
Thank you, Arvin. Nicely done.
To assume they have a purpose is to admit intention.. a creator. Good work!
Wait, neutrinos can change flavors because they move slower than the speed of light. Thus, time passes for them. But if in the perspective of photons, time doesn't exist, how they change wavelength. I know the change of neutrinos is more of a mass transformation, but the photons frequency is more of an energy transformation, from the momentum. But mass and energy as we know are linked
Thats the first time I've heard, and understood, about how photons are made. Love your channel.
neutrino helicity finally makes sense! thank you for your eloquent explanations
Also your kind of socratic style of rhetorical questioning structure feels natural, as students and teachers interactions in the classroom. At least this is what I am accustomed to.
Big ups. As a life long learner I say "thanks" it's pretty clear. Yet incomplete. PS: I am still trying to mine. 🥂🤔🤪😏🥂
Shouldn't the electron-positron collision create 2 photons ? For the momentum conservation.
Very well done Arvin.
Very educational.
They should allow such videos in schools for better understanding for the students.
When I learnt about neutrinos at uni, I kind of pictured them as little tiny particles of energy converted into mass in it's most neutral form. It helps visualise it and that's how I understand things.
I wish these videos could be more than 15 minutes long. I could listen to this stuff all night.
I would love to hear your take on how it is we can know right-handed neutrinos don't exist. As far as I understand, neutrinos only interact via the weak force. Only left handed particles and right handed antiparticles carry isospin and participate in weak interactions. Assuming some mechanism, like Higgs, allows neutrinos to change chirality, it seems perfectly reasonable that right handed neutrinos could both exist and be for all practical purposes unobservable.
That particle on 13:14 alongside electron is anti-neutrino, right?)
All these concepts pass right through my brain, just like neutrinos, without hitting a single neuron.
