I understand the connection between the Lagrangian and symmetry, but I don't know where the Lagrangian itself comes from. Why do we subtract the potential energy from the kinetic energy?
This video is so good I'm returning at it after 8 months or so. My 18th bday is on the same day as this channel's first anniversary haha. I'll probably comment something on that day too. I don't want to force anything to you Orla but I'm still waiting for a second video by you if you can. You are such a good explainer as well as SoME2 is coming soon haha. Anyway, hope you're having a great time!
Really really good video, thanks so much for making it! And to leave you with a bit of feedback: the only thing that could've been better is the recording or the pronunciation of the things you've said, sometimes it's not a hundred percent clear (but it was good enough, I understood it even though I'm German and English is not my first language) And I also get that audio equipment is expensive, recording stuff multiple times is not fun and all that stuff, I just wanted to leave some feedback, in case you would do another video and want to know things you can improve :)
Thanks a lot. Best explanation ever of this difficult stuff. I wish i could be part of your lecture auditorium... unfortunately i am not a student. Best wishes from Germany
Absolutely amazing video. I have a maths background, but only minimal knowledge in physics. I have already seen quite a few videos about Noether's Theorem, but this is the first one that really made sense to me.
Omg you made this so clear I literally slapped my forehead. I've always struggled to understand how symmetries were related to conservation laws and this just made it seem so obvious! Great job.
I never had the subject in such a efficient and clear way! Dissecting the equation of motion was really useful. Are cyclic coordinates like rings in algebra? Great work!

This is really an incredible video. I feel I understood at first go the simplified math behind Noether's theorem, and got the Euler-Lagrangian equation to boot.
Wow, looks like I've returned after 1 year again hahaha! This is my third time!
thank you so much for this video!!!
Amazing video! Only one tiny thing that botherd me is that the sound was way down. Maybe speak loudly next time please? Anyway amazing video
Excellent explanation.
oRLA ? are u from Brazil?
the speaker's accent sounds a bit Irish
Noether was the shit. Hands down one of the most impressive mathematicians our species has ever had the honor of producing.

Yes! I can ignore the content and still feel some form of meaning.

Thật tuyệt vời khi đến với định lý Noether
Im super surprised on simpler this is than i expected. Either that or you're a incredible teacher, nice video.

Very Interesting Great Job!
Will you make any more videos? This was so fun :)
Thanks. Such a nice explanation
Excellent!

Damn, these SoME videos just keep on giving, yet another really good one!
Such an enthusiastic narrator!!
Super lovely video .. but if u can slow down while u speaking cause from now on, u have non English speakers
Beautiful
“You can’t say anything useful about a foundational theorem of theoretical physics in five and a half minutes.” And then I was wrong.
Thanks a lot. Best explanation ever of this difficult stuff. I wish i could be part of your lecture auditorium... unfortunately i am not a student. Best wishes from Germany
I actually understand this now thank you
Nòther theorem accept
Nòther theorem accept
Make more video please. About intermediate stuff. Or intuitive stuff that are not clearly written in a book
Absolutely amazing video. I have a maths background, but only minimal knowledge in physics. I have already seen quite a few videos about Noether's Theorem, but this is the first one that really made sense to me.
Loved It
Good video. Please do more such interesting videos..
Omg you made this so clear I literally slapped my forehead. I've always struggled to understand how symmetries were related to conservation laws and this just made it seem so obvious! Great job.
You are amazing Orla !! Love from India ❤️
This is really nicely done out. For me Noether's theorem still remains the most interesting thing I've ever studied in physics.
Beautiful video! Can you point to an article where they prove the rest of the conservation laws?
Excellent job! I hope you make many more videos!
the best , faster , inuitive explanation I saw in my life on the topic. I hope you do more videos !!!!
Great video!
I never had the subject in such a efficient and clear way! Dissecting the equation of motion was really useful. Are cyclic coordinates like rings in algebra? Great work!
Thank you so much for sharing!
Wow! This video was spectacular
Wow, need to learn abstract algebra now to understand physics 😭
Expanding electrons cannot be destroyed; energy is now debunked- actually 19 years ago. Try to keep up.

There is a symmetry for the conservation of the Action?? (trying to relate the intuition of the video with the principle of Stationary Action)
that was such a good video! congrats from argentina!
thanks always wanted to understand the proof, and now i do just the right level
If 3b greeted, you know you are good..thanks...
Nicely done ...
Such a beautiful explanation, you just showed the essence of Noether's Theorem. Thank you very much <3
This is beautiful! Thank you
