For the first time in my life, a comprehensible explanation of why neutrinos are different and can change. Nobody else seems to bother with giving a comprehensible explanation. They say neutrinos have the same zero charge and mass and energy but yet they're different and they change with time. That's it. Not an explanation of how this is possible. But you have done an excellent job in figuring out a way to describe it. Thank you
first time on your youtube channel ,as everyone says "FIRST IMPRESSION IS THE LAST IMPRESSION" your way of teaching is very impressive. the way you explain things with examples and with jokes it makes your style perfect.in short we can say That we are learning Physics with Fun. Thank you so much for your efforts & carry on.
Thanks so much for this I am a physicist but not a particle physicist. This was a brilliant exposition of the neutrino oscillations! Hats off to you mate!
I can't help but really appreciate your approach! Thank you for making these videos. I want to make similar contribution into Greek someday soon! I have been teaching medical physics for some years now and the Greek literature is very poor. Your videos have the perfect amount of simplicity, similarly to what I do in my lectures and what I think that medical students need. Your work is very carefully planned and executed. Thank you for sharing!
Like others have said, I have too been looking at a few videos about this subject trying to wrap my head around it, and this has been the absolute best and most helpful one so far. Thank you so much!
Liked and subbed. Rare for science videos to communicate actual science to the herd. Usually just dumbed down, half witted descriptions that create more questions than they answer
This video is a wonderful exposition of how the neutrino problem indicates new physics. Larson's Reciprocal System postulates the three neutrino flavours as follows: The neutrino triple notation shows that the uncharged neutrino consist of both a magnetic and electric rotation and that collisions give these rotations a charge or rotational vibration. The magnetic charge is two dimensional and therefore takes 720% to complete compared to the electric vibration which is one dimensional and takes 360 degrees to complete. Larson explains that the uncharged neutrino is massless (because it has zero net displacement) and is carried by the progression as a form of radiation, but acquires mass from the magnetic charge which causes it to become trapped inside an atom whereby it imparts its magnetic charge to the atom as one unit of vibrational mass.
As mentioned by others, I finally get the concept. You really have a talent for making esoteric concepts comprehensible and I (we) appreciate it greatly. Your jokes are pretty bad, too, and that makes learning even better. Thank you.
I really appreciate the way you have explained the very basic things about neutrino oscillations. We have studied these concepts so many times but it was always confusing due to our less imaginative thinking.
Very, very, very helpful. Insightful, intuitive and comprehensible. I have to be honest, I was a bit discouraged when it was 20 minutes long. But after a minute into your video, the 20 minutes feels like nothing! I personally have trouble when my lecturer jumped to the math without going through the concept of it. For example, the matrix form you showed. I didn't understand it at first when I went through the notes, but after this video, things are much clearer. Also, I loved Wu experiment video so much! Thank you and may you be blessed with great health :)
Best physics channel.. This is the only video I've seen which gives a clear & intuitive explanation of neutrino oscillations 💯.. So now I'm binge watching all your videos 😁.. ☮️
Don't do comparison.. walter lewin is a legend in his own way... you can't say einstein is the second newton.... he is the 1st and one and only Dibya jyoti Das..
Hi, Hope you are doing good. Your videos are superbb so thought writing this. I had one request can you please make a video on Deuteron problem. What is its ground state and why it is called loosely bound system why it has no excited state. And how Deuteron led to discovery of Non central forces. Please looking forward to understand this topic. :)
Very rare to find such great physics teachers like you brother ( as I am elder to you I am avoiding Sir ) !! Wonderful explanation of Neutrino oscillations 🙏🙏
Yes. These experiments have been performed over 40-50 years because no one wanted to accept the oscillation theory. But at the end the evidence was overwhelming enough
Sir! With all due respect, I would like to entitle you as Dr. Feynman Vol. 2 !!! Great video... I want to have that level of knowledge, and that level of explaining complicated things so well and so easily, as you have. I want you to guide me to where you are...
Great lectures Sir I have been watching all ur lectures...for better understanding, but here I have a question..Have we put all 3 neutrino flavored detectors and then calculated the difference?? Sir what if the difference is still there..will this explanation be valid??
It is really an amazing lecture..Thank you sir for your effort...If You Could make a lecture on CP violation and Mixing Angle...That would be really helpful.. Thank you
What is the proposed mechanism by which this happens? Which of the 4 fundamental forces causes this to occur? Incredible video - just wondering this part.
If you understand Faraday rotation in the ionosphere, you're good to go neutrinos. the 2 circular polarizations are analogous to mass eigenstates the propagate at different speeds (at fixed energy) through the ionosphere, while linear polarizations are analogous to flavor eigenstate (what the reactions create). So if you transmit a certain power of H-pol from space to earth, that H, which is part right and part left handed circular polarization, will rotate (read: oscillate) from H to V and back as it propagates, so you may detect "missing H pol energy".
Thanks very much for another excellent (and easy to understand) video. What happens to the conservation of the Lepton numbers (from an earlier video)? Is this the new physics to which you were alluding (besides neutrinos having mass)?
Yes. Neutrino oscillations violates conservation of lepton number principle. As of yet standard model cannot account for either the mass of neutrinos or this kind of change in lepton identity
Well, this is interesting, but are these oscillations really "probabilistic" if the phase relations between the two sinusoidal functions follow a regular pattern or deterministic pattern. Or, put another way, is it really the measurement (not the fundamental oscillation process) that is probabilistic since we don't know what phase relations the two waves will have upon measurement?
Its a great explanation ! but how energy is conserved , as electron neutrino has less mass and meuon neutrino has more mass so there must be some external energy required for converting electron neutrino to meuon neutrino ( or may be energy of electron neutrino is converted to meuon neutrino and meuon travels bit slower than electron neutrino for energy conservation )
Each neutrino type has different mass. How neutrino gains and sheds mass to change its flavour? EM waves add and subtract. How a probability wave which is not a physical wave change neutrino mass? Is there any interaction which can change a particle's mass.
There is a fascinating children's toy called a "bullroarer" in north America, a flat piece of wood with a string attached at one end. Then when you spin it it begins to spin in 3 different axes or dimensions simultaneously. Much like neutrino. Spinning in all directions but without inflow/outflow=charge.
I am usually suspecting about Indian Videos, but from your this video, I really got the feeling that you do truly love physics. This is really amazing, but a question I thought the major process going inside our star is CNO cycle than pp process, I can be wrong but can you just confirm?
But WHY do they have this property? Is it just something quantum-mechanically fundamental we have to accept, like quantum spin? Could the other leptons also have this property, but in a way that we been able to detect yet?
I can't remember where but I saw a video that said that the difference between the favour of neutrinos is their mass and the particles they produce when interacted with This theory would contradic that has any neutrinos could produce an electron for example if given enough time to change its flavour Also would the change in mass violate conservation law?
@@FortheLoveofPhysics Funny enough I just started to watch your lepton video where it talks about this so the other video I saw wasn't wrong The only way I see this mass change would be through the weak hyper charge but I thought that would only be possible when a particle changes their spin
'In phase' and 'out of phase' is simply used as a visual representation. In essence, the flavour is the result of the mass-states combining in different proportions, u can say. For eg, ac to my example, if three waves = c1*sin(x1*t) + c2*sin(x2*t) +c3*sin(x3*t) then the "flavour" is a result of amplitudes (c1,c2,c3). So if electron neutrino is created by values (1,1,1), then muon neutrino has values (1,1,-1) and tau has values (1, -1/sqrt(2) , -1/sqrt(2)) acc to the representation n video
Though I understand each one of us has a paucity of time and have our own plans, still I would like to make an earnest request. Here it goes... It would be great if you can suggest about timings of upcoming video in advance and the topic.

Can we take a moment to appreciate the fact that he was staring at a blank board for the majority of the video. Respect Sir !
Was wondering the same thing. Extreme dedication levels...
A fantastic explanation combined with stunning visualizations. It's the clearest and most intuitive depiction of neutrinos I've encountered.

Does this solar neutrino deficit remain constant over large observation time?

Do neutrino oscillations affect neutrino speed due to constantly changing frequency and wavelength.

Or, put another way, is it really the measurement (not the fundamental oscillation process) that is probabilistic since we don't know what phase relations the two waves will have upon measurement?

What about other leptons? Could a similar idea explain the electron/muon/tau, or why not?
Itz crystal clear, thank u so much sir 🙏

I finnaly understand a bit about neutrino occilations thank man❤
Are existing detectors being modified, or new ones put in to detect mu and tau neutrinos?
Have scientists got new data to confirm this theory?
Mixing angle ka significance kya he ???
There is a fascinating children's toy called a "bullroarer" in north America, a flat piece of wood with a string attached at one end. Then when you spin it it begins to spin in 3 different axes or dimensions simultaneously.
Much like neutrino.
Spinning in all directions but without inflow/outflow=charge.
if the neutrino itself has infinitesimally small mass then what about the mass of mass eigenstates?🙃
Thanks sir

Electron neutrino in phase, mueon neutrino 180 °out of phase then what about tau neutrino? I didn't understand
'In phase' and 'out of phase' is simply used as a visual representation. In essence, the flavour is the result of the mass-states combining in different proportions, u can say.
For eg, ac to my example, if three waves = c1*sin(x1*t) + c2*sin(x2*t) +c3*sin(x3*t)
then the "flavour" is a result of amplitudes (c1,c2,c3). So if electron neutrino is created by values (1,1,1), then muon neutrino has values (1,1,-1) and tau has values (1, -1/sqrt(2) , -1/sqrt(2)) acc to the representation n video

If a single neutrino wave travels then what kind of neutrino will it be..?
