Seems to me... if you were wanting to convey a strict understanding of Noether's theorem then you would've gone heavy on the maths. But you were going for understanding a concept, so the only way I can truly consider your words to be "misleading" is if I'm just trying to be a ∆!¢k about it.

I'm lost beyond fuck. But mostly because I can't math. All those greek symbols are just scrambled eggs. It's still very interesting, the parts I understood.
Watch PBS Space Time episodes on Noether's theorem. Also, same show has a good episode on this topic, called, um, quantum invariance something something... you'll see it. Much more in depth.
I think it’s becoming expected because of the format that you can slow down, pause or repeat anything that is bothersome. UA-cam can let you experience it all at half the speed if you like :) I’m going to have to do that with some of the earlier videos to get a better grasp of what was presented here.
Yeah... this one's going to need several viewings! There has to be at least an hour's worth of material covered in under ten minutes. Still, I'm sure it's almost impossible to simplify this topic. Thank you for continuing to treat your audience as intelligent, rather than dumbing down for cheap view counts. Really appreciate that!
Yeah, this is a problem we all run into with quantum mechanics. If you remove the math from QM, there's barely anything left to talk about. That's basically all QM is.
@@ScienceAsylum breaking down the math into intuition is hard to do. I follow the formulas when you explain what they are doing. When they are applied to the EMF I become lost trying to find the connections between the formula's parts and what is going on inside of the model of the field. I probably have to rewatch it to understand it better. When I really follow what's going on, I can see why you're mind is blown because I definitely have those moments too. Thank you for sharing your knowledge, I appreciate your videos.
Great video To be pedantically precise, Noether's theorem says that every continuous symmetry is linked to the conservation of some charge, but not all conserved charges are due to symmetry. Some charges have topological nature (if there were magnetic monopoles, their charge would be topological and not a Noether's charge).
@@yashagnihotri6901, As far we know there are no fundamental particle with topological charge (like the magnetic monopole), but condensed matter have plenty of topological deffects with topological charges.
It was an astonishingly efficient way of breaking down the fundamentals of a very complex subject. The usage of analogies is truly enlightening, not to mention that the structure of categorization you implement is perfectly consistent. I cannot express the value of your work properly. Thank you, sir!
“We might not know what they are, but their behavior is described by waves of probability.” Exactly! I wish people would stop saying that electrons _are_ waves when the reality is that we don’t know _what_ they are. We do know how they _behave_ though, and that’s far more important.
idk electrons are electrons, and we use the mathematics of waves to describe their behavior. there is no need to figure out "what they are," only what their properties are. there is a sense in which it's not really meaningful to talk about "what they are" beyond excitations in a quantum field. At some level you reach brute facts, and you can only describe things in terms of their properties as mathematical objects but that's just the universe for ya.
@@josephlombardo1246 Yes, that's what I was saying. We don't _know_ what they are, but we do know how they _behave_ and that behavior is dictated by their properties. That knowledge is far more valuable.
All particles are vibrations in a quantum fabric. This fabric is a 3d+1 hyperfluid "something" The theories that describe this are called Quantum Field Theories. Particles have no actual distinct dimensions. They are not balls or any solid thing. Their physical trajectories are fuzzy and that creates probabilistic shapes that vary but the corpuscular view of elementary particles is just an illusion.
I can't believe I posted this only a month ago! Over the past couple weeks I've become convinced that electrons almost certainly _are_ actual physical waves in quantum fields. That's so ironic! I don't know that I've ever changed my mind about something so completely in such a short time (at least not something I've spent so much time thinking about.)
I had a hard time understand physics from solid objective prospective as a teen learning about science. My biggest issue is that each time you say a particle has an exact size and shape that begs the question. Well then what defines that object? More particles? At some point things must be vibrations or motions of some medium or fabric.
There's a lot to absorb in this video. Concepts explained clearly infer a deeper intuition that I'm honestly struggling to process without having to pause the video. I think this will prove to be a video that is worth returning to multiple times as you incorporate all the nuance from continued study with the goal of deeper, but also more intuitive understanding. Good job!
I have been here since you were at 10k subs and even commented that you are one of the most underrated science channels. This video again just proves my point and I will see u again once u hit a million😉
I think the cardboard look for some of those drawings is absolutely darling! Now, this video will need a couple of viewings to let it soak in, but with the rest of the explanations of electricity & how it works, it really helps, because it goes to the subject from a bit of a different perspective. Thanks so much for that!
@@Zeegoku1007 well, it IS nice that her work has become better known over recent times. Groundbreaking stuff at the time, and underpins much of physics that we now study.
PBS Spacetime is where I go to learn new things about physics. Science Asylum is where I go to learn that I have to relearn what I thought I knew about physics.
Definitely your most complicated video, but also fascinating. Thanks! And I remember that dreaded A vector from Electrodynamics. Makes me want to revisit it and give myself a better understanding.
Awe inspiring. Can't say I understood more than ~25%, but hey....I always felt there must be something that would pin down the "arbitary" extra functions on the electric scalar and magnetic vector potentials. I suppose quantum mechanics would have to come in somewhere....Keep up the great work.
It's inextricably good to understand for those like me who always trying to grasp Quantum Theory from it's root. Thanks for this magnificent contribution of Explanation.
That's a fantastic explanation of phase invariance. You covered a lot of ground in a single decaminute but I found it very electromagnetically illuminating. After the little teaser, I'm hoping for a video or two on relativistic QM - a fun challenge. :-) Thanks for all the energy you put into these videos. It's time well spent.
The quality of information and clarity despite being dificult topics (if one wants to truly understand them) is a great benefit to the youth. Thank you.
I loved the video but you just show the symbols. Show a little more of the maths. Like just putting the gauge function in and show that it doesn't do squat to the original function. And give things some more mathematical sense. We really can't appreciate these topics without the maths. But its great that you are actually covering such an important topic that others just take as a given or shrink at the requirement of explaining. I am your fan. You bring me real value and cover the best, most useful and complicated topics. Thank You.
Hi Nick, I m quite impressed by this video. I ve never come accross any vulgarization articles or videos about charge, phase invariance and EM gauge. This topic is thought to be too complex or mathematical to be explained. Many thanks for the effort of busting the white lies and dubious analogies we are told to simplify our understanding of physics. As a contrary I think the difficulties, the counter intuitive concepts and fine descriptions are the heart of seeing physics as logical system.
Nice way to precisely explain the fact that the charges of particles are really about relationships between the rotational motion of said particle & the overall motion of the local fields created by the particles.
Wow that’s a lot of mathematics covered in such a short time :O in my own videos I always end up abstracting the mathematics away a bit more for the sake of clarity, but it is honestly inspiring to see it not done like that, while still yielding a thorough and clear explanation! Awesome :D!
I don't normally have this much math in my videos. I've just been sitting on this video for a year now, tweaking it a little bit at a time and never being happy with it, so it was time to let it go. I needed to be done with it.
The Science Asylum I hope you are nonetheless happy with how the video ended up! Not sure if it helps, but I think it is impressive to see gauge invariance, Noether’s theorem and the physical implications compressed into 10 minutes. That’s everything but easy, especially while making the explanation as understandable as possible, but I think this video does a great job at that :-)
👽The State of the 5th DImension is "Action & Cause" AKA "Effect & Affect" of the Probability of Matter (5th Dimension Light 5th DImensional Matter). And this video explains it! Bravo! 💜
Your videos are great! I would love to see one covering the topic of why spin half particles follow Fermi statistics, and integer spin particles follow the Bose-Einstein statistics. Thanks in advance.
Fine video as always - but I have two simple questions about charge that I cannot find an answer to. 1. Why is the attraction from positive to negative, and never the other way around? 2. Why is the positive charge in the nucleus and the negative charge outside? Why isn't it the other way around?
1. If you ask "why" enough times, the answer will eventually be "because it is." That's where you are with this question. 2. It could just as easily have been the other way around. It just so happens that the more massive particles are positive (so they move less). In antimatter atoms, the negative charges are more massive so those are the ones in the nucleus.
Hey Nick! Iam really a big fan of you. I love your videos a lot. I always wanted a teacher like you. And the way of expressing the ideas is really awesome. I always wished to see you hit 1M and grow like veritasium and physics girl . So keep hope Nick . I'll see the day when u hit 1M very soon.
Here I go again, just a regular person , watch again to TRY to memorize terms and concepts, to start forming tiny ideas that combined with more memorizations and clarifications will result in the beginning of understanding what this video is about. Wish me perseverance
What another comment said should have been the end summary, in layman's terms this means the charge of a particle cannot change therefore the particles with charge are changing the field.
1:13 Once you corrected me with that hehe. Thanks. 3:37 It'd be great to watch a video on potentials, that was one of the most abstract ideas in electromagnetic theory courses.
I don't know how to make potentials interesting by themselves. This was my best attempt. I tried talking about why they're important. Abstract mathematics isn't really what I do on this channel.
@@ScienceAsylum Hi Nick! What about a video on voltage? I think you don't have a video on that. Perhaps it will require to talk about electric potentials. 🤔
Guitar pedals circuitry and why speakers have a phase switch is a good reason to try and grasp a basic understanding of this interesting topic. Thank you for the clarity and humour that can make these great clips easier to watch more than once. Who programs the backing music?
Aside from my three-second intro song (which I made), the rest of the music is from the UA-cam music library (because I know I won't get a copyright strike over it).
I have always thought, that one of the fascinating things about our universe, is that different observers will disagree about “components” of a system, but all observers will agree on the results. For instance, different observers will disagree about the total momentum of a system, but when forces are applied, all observers will agree on the results. So, while total momentum is not reference frame invariant, all observers will agree on the changes. Total energy is also not reference frame invariant. Different observers will also disagree on the changes is energy, but all observers will agree on the results.
I adore your channel, and *usually* I can follow. Not always 100%, not always first time through, but I can get it. This video, however... You need to make like four or ten videos unpacking each little bit. Please.
@5:17 you say something really interesting about how we don't know exactly what particles are, but we know they aren't spheres. I would love to see you make a video that explores what theories there are for physical properties of particles. Love your channel!
I watched it twice, maybe even thrice with so many segments I had to rewatch again and again (my mind tends to wander a lot), and I'm still sure I do not understand everything. But that's probably because you compressed a whole course on fundamental physics in a 10 mins. video. There's a lot of info on the fundaments of Reality in this short video: it's thus extremely hard for any non-specialized human being. I'll rewatch a few more times probably: it's extremely good: a very dense pack of knowledge. TY.
Yeah , being in 12th grade right now , obstructs my limited knowledge to understand the concept of 'Gauge' included in the video rest all was a bit easier to grasp. Probably today I will read about it (Guage or whatever it is )
At 8:03, assuming particle interaction with the em field is described by the Schrodinger-Pauli equation, how do you prove those things are equivalent? I can see how you can derive phase invariance from the form of the S-P equation, but can you go the other way around and deduce S-P from local phase invariance (and maybe say the basic Schrodinger equation) ?
In other words, local phase invariance alone corrects the Schrodinger equation into the Schrodinger-Pauli equation ? And what's a book that tackles the maths of that ?
I love all the videos on this channel but this one is the most obscure and hard to understand so @The Science Asylum if you ever consider a revisit or expand to one of your videos please choose this one! 😺
I only understood like 20% of this video but it makes me really excited for my first year in college next year as a physics major (hopefully it won’t be online)
That first "FUCK YEAH THERE IS" made a little bit of my drink spray out my nose! I just wasn't ready for it and didn't suspect it. I mean, I don't think it was objectively S-tier funny, but there was just something perfectly timed and placed about it. Always love seeing a new vid from you in the notifications. Great video sir.
You could have used QFT, and used nother's theorem for the quantized dirac field, to get conserved quantities like spin and charge based which index of QM stress energy tensor is 0. This would also be a great explanation for relativistic particles too.

@@davidhand9721 I think this one is better than what PBS spacetime did (and I think PBS did a good job). The lectures about this are usually terrible.
What are you doing knowing gauge invariance as a physics major lol
In what physics major are you learning gauge invariance? Seems like a graduate topic
I like how this channel goes into deep concepts. A lot of science channels scratches only the surface so that it's more digestible to the masses.
We had the meme:"Actually, Quantum Mechanics forbid this". Now, we have the new one!: "Quantum Mechanics requires this!"
I came to comment section as soon as I heard him saying that 😂
Yea he even made it into a meme format with the placement of the words and choice of fonts too!
Wasn't it Gell-Mann or someone like that who said something like "That which is not forbidden is mandatory" when referring to quantum mechanics...

I am happy to learn modern physics from your video.
I feel smarter and dumber after watching these videos. :)
Soo true
Relatable
You are the best Thank you ! Few months ago I saw Your video on The principal of least action and it got me so interested at your channel!
I think you are an 👽 alien send to help us grow. That explains the clones 👻
So complicated and also so simple(in some ways).I mean it's good to know what's around us and how it's work. Keep going ☺
Almost first... Yeah
Edit: Science, Mr White
Yeah science, bitch!
Excellent! Charisma and intellect and a good sense of humor
Would it be possible to get videos about coupling and symmetries of the strong and weak interactions?
This will happen eventually, yes. It's just a little more complicated than electric charge. Need to do more research first.
This video made a lot of sense about notions I didn't fully understood 10 years ago, back in grad school. Thanks.
Glad I could help 🙂
This video is packed with information and funny as heck. I am sure I will come back to this video many times.
Absolutely TRUE!!!!!!!!!!!!! In so many senses of the way! Brilliantly done! Brilliantly seen! Totally clear!
Like mass, electric and magnetic charge are are independent entities. The 3 join in specific ratio to make particles.
I've been searching for a video like this for a ton, nobody else on internet has talked about it, not even matt'o'dowd
Sapcetime did actually cover this, it just took a few videos to go over it. I think they have a playlist on QED
@@timh.6872 Really, well...sorry my bad, guess i wasn't good enough with my research...still happy that nick did something
This video was supposed to happen a whole year ago, but I decided it wasn't ready then.
Here I go again, just a regular person , watch again to TRY to memorize terms and concepts, to start forming tiny ideas that combined with more memorizations and clarifications will result in the beginning of understanding what this video is about. Wish me perseverance
What another comment said should have been the end summary, in layman's terms this means the charge of a particle cannot change therefore the particles with charge are changing the field.
1:13 Once you corrected me with that hehe. Thanks.
3:37 It'd be great to watch a video on potentials, that was one of the most abstract ideas in electromagnetic theory courses.
I don't know how to make potentials interesting by themselves. This was my best attempt. I tried talking about why they're important. Abstract mathematics isn't really what I do on this channel.
@@ScienceAsylum Hi Nick! What about a video on voltage? I think you don't have a video on that. Perhaps it will require to talk about electric potentials. 🤔
Nice explanation bro👍
Difficult to follow, but you’re excellent explaining! Thank you, Nick! Best regards from Brazil.
Guitar pedals circuitry and why speakers have a phase switch is a good reason to try and grasp a basic understanding of this interesting topic. Thank you for the clarity and humour that can make these great clips easier to watch more than once. Who programs the backing music?
Aside from my three-second intro song (which I made), the rest of the music is from the UA-cam music library (because I know I won't get a copyright strike over it).
You're amazing Doc
I have always thought, that one of the fascinating things about our universe, is that different observers will disagree about “components” of a system, but all observers will agree on the results. For instance, different observers will disagree about the total momentum of a system, but when forces are applied, all observers will agree on the results. So, while total momentum is not reference frame invariant, all observers will agree on the changes.
Total energy is also not reference frame invariant. Different observers will also disagree on the changes is energy, but all observers will agree on the results.
I adore your channel, and *usually* I can follow. Not always 100%, not always first time through, but I can get it.
This video, however... You need to make like four or ten videos unpacking each little bit. Please.
I agree. This needed an entire series. It's too compressed.
@5:17 you say something really interesting about how we don't know exactly what particles are, but we know they aren't spheres. I would love to see you make a video that explores what theories there are for physical properties of particles.
Love your channel!
I watched it twice, maybe even thrice with so many segments I had to rewatch again and again (my mind tends to wander a lot), and I'm still sure I do not understand everything. But that's probably because you compressed a whole course on fundamental physics in a 10 mins. video. There's a lot of info on the fundaments of Reality in this short video: it's thus extremely hard for any non-specialized human being. I'll rewatch a few more times probably: it's extremely good: a very dense pack of knowledge. TY.
Yeah , being in 12th grade right now , obstructs my limited knowledge to understand the concept of 'Gauge' included in the video rest all was a bit easier to grasp. Probably today I will read about it (Guage or whatever it is )
2:26 best part
can't say I understand anything any better, but you did a great job
1:43 More specifically, it is a number that stays the same throughout every possible interaction between the things involved.
At 8:03, assuming particle interaction with the em field is described by the Schrodinger-Pauli equation, how do you prove those things are equivalent? I can see how you can derive phase invariance from the form of the S-P equation, but can you go the other way around and deduce S-P from local phase invariance (and maybe say the basic Schrodinger equation) ?
In other words, local phase invariance alone corrects the Schrodinger equation into the Schrodinger-Pauli equation ? And what's a book that tackles the maths of that ?
man this is one of the best videos you have ever made
I love all the videos on this channel but this one is the most obscure and hard to understand so @The Science Asylum if you ever consider a revisit or expand to one of your videos please choose this one! 😺
I always love your quantum mechanics videos.
I only understood like 20% of this video but it makes me really excited for my first year in college next year as a physics major (hopefully it won’t be online)
I hope it’s in-person too! Good luck!
never seen
this deep version on charges and EM interaction
I can't express how nice this video is. Well done
Thanks! 😊
That first "FUCK YEAH THERE IS" made a little bit of my drink spray out my nose! I just wasn't ready for it and didn't suspect it. I mean, I don't think it was objectively S-tier funny, but there was just something perfectly timed and placed about it. Always love seeing a new vid from you in the notifications. Great video sir.
Everything gone over head...but enjoyed watching 😂😂😂
I appreciate your hard work for explaining deeply.😊
I will watch this a few more times. Thank you.
Excllent explanation of guage invariance
Thanks! This video was difficult to write.
@@ScienceAsylum yeah I bet it was, I will use that explanation and your video in future physics classes
You could have used QFT, and used nother's theorem for the quantized dirac field, to get conserved quantities like spin and charge based which index of QM stress energy tensor is 0. This would also be a great explanation for relativistic particles too.
can you talk about stephen wolfram theory of everything?
I havent watched you since you had like 3k subs im glad youre doing great and only on the rise.
Where have you been? 🤔 I hope everything is ok and it's just that UA-cam hasn't been showing you my videos.
Laughed heartily at the quarantine crack!!! 🤣😂🤣
