Thank you for this video. I’m tired of hearing these “celebrity” scientist talking about QM so abstractly. I understand that is their role (to develop interest to the general public) but us engineers and physicists, need this type of content as well. 🙏
I'm not a physicist or engineer, but I've developed a strong interest in physics, and have studied many math concepts to understand what certain expressions actually mean, and where certain conclusions come from. This kind of content is what I'm looking for too.
what's fascinating to me is that in classical mechanics, the potential seems to be able to take any mathematical function of (generalized) position and momentum, but the "potential term" in field theory is limited to powers of the field. No weird terms like exponent, log, or sine and cosine of the field
Amazing how simple the Higgs mechanism appears after you see this lecture. A real example of great teaching. I have seen a dozen other quote lectures and none can hold a candle to this one. If only there was an explanation of why the Higgs potential goes to zero as the energy increases.
Ack... sorry. Yup.. a typo. The main point is just to show that there are other lagrangians for different circumstances. Thanks for the comment. I'll try to make an annotation at some point...
Thankyou so much for this wonderful teaching. I have a question that I always had since I was undergraduate , how did scientists come up wth thise lagrangians? I mean does one just think of a langrangian that leads to a certain law and says ok this the lagrangian for KG eq, this for Dirac spinors, that is for QCD.....or is the thing much deeper?
I think it's like most other aspects of science: Come up with an idea that seems plausible and then see if it works. Of course, there's a lot of work that goes into developing an intuition about the kinds of things that tend to work, and how to formulate physically interesting terms, but in the end you don't know until you can measure the effects of the interactions to see if they match the predictions of the theory.
@ 17:38 Here I would have explicitly shown that phi is a function of spacetime-coordinates too. P.S. Isn't the "Ack"-exclamation pointing to the wrong term?

Hi, I was just wondering: why does the mass come out to be m = sqrt(2) M at 26:33? Is it just sqrt(2 x the coefficient) by comparison to the first Lagrangian? Thank you for a great video.
+HoboProber I'm glad you found it helpful! It's not profound really. My thinking was just that the original was (1/2)m^2 phi^2, but this one is M^2 eta^2, so M^2 is acting sorta like (1/2)m^2, so m~sqrt(2) M.
A theory is describing and explaining a phenomenon. It has to be testable. Otherwise it is becoming a kind of religion. So we can only talk about a string hypothesis.
@Asyam Abyan Over the last 50 years nobody could do anything useful with string theory. Because you can't test its predictions it is non-scientific (like religion).
@Asyam Abyan Proven wrong? You can't prove String "Theory" wrong. It can't be tested. It is intellectual power-lifting for the Happy Few. Listen to him for a minute: ua-cam.com/video/5EFWbPOVsL4/v-deo.html

I guess I am kinda randomly asking but do anybody know of a good place to watch new series online ?
I'm not a physicist or engineer, but I've developed a strong interest in physics, and have studied many math concepts to understand what certain expressions actually mean, and where certain conclusions come from. This kind of content is what I'm looking for too.
Wonderful lecture! Also, thank you for the shout out when presenting the SML in the beginning!
Thank you! Very kind of you.
Finally someone who explained it in a way that is understandable to a physics undergraduate! Wow!
what's fascinating to me is that in classical mechanics, the potential seems to be able to take any mathematical function of (generalized) position and momentum, but the "potential term" in field theory is limited to powers of the field.

This is amazing, please keep doing more!

this presentation is absolutely amazing!!!
29.10 Mind blowing!
Entertaining and educational!
Thank you very much Sir, Very nice explanation

Thank you so much for the video ❤️
thank you! Finally a good video about this with the math!
Yet I feel like Higgs boson was not pointed out where it showed up. right?

Im in school and trying to understand how this stupid world works. This is why I am here.

Cool !!!
Thanks... This really helped...

Thank you very much! That definitely makes sense and seems to be what's been done in the textbook I'm using.
So is 22:19 the standard model equation
In what year of uni does one learn these concepts ?
I would say mostly graduate school, but also Jr/Sr year sometimes if there's an advanced QM course.
Lecture should include flavors,other sm particle,su3,2,1 group operations,and more matter force interactions,otherwise it was good
Lesson 39 is 39 minutes long.
Vennisa Barfi oohhh that’s incredible! I probably couldn’t do that if I tried to do it on purpose.

@Asyam Abyan give other use of Chystofel symbol,other than relativity
@Asyam Abyan I think you mix up methodology and physics.
