Congratulations for the content. I have two questions and I hope somebody here can help me. First; what is the weight of the elctromagnetic field stregth tensor, T? I mean, if sqrt(-g) is a tensor density (or relative tensor) of some weight and J, the current density, is a vector, T must be a tensor density too? I've always been told that F is a rank two tensor. And second; regarding the gauge invariance of the J•A term in the lagrangian, is there an argument for gauge invariance without the requirement that A and J vanish at infinity? I get that this is sensible at spatial Infinity due to convergence, but imagine that you are solving the problem for a fixed interval of time; then the conditions on the current and potential are a bit wierd I would say. Maybe this is not so bad or there is an argument which does not requiere this assumptions.. Thanks in advance.
I don't provide the documents, because I want people to have to watch my videos. I only get any kind of reward for my effort when people actually watch my videos, so I am uninterested in spreading documents around that would make watching my videos unnecessary.
@@Terminator_420 I am interested in getting paid for my work. How is it fair for me to have to do all this work for free? I could just not go to the trouble at all.
Thank you for this derivation.
Superb explanation.
Thanks for the support!
can you please provide the these notes in pdf or word file..? Please
Most famous form of M.E. is the differential form I'd have to say
The Fermi Lagrangian is pretty neat.
Could you please give a link to share the script? many thanks
Are you only in the first year of grad school or are you currently pursuing PhD Research ?

For clarity: in the first question I'm looking at the second version if the inhomogeneous Maxwell equations we see in the video
The answer to your first question is 2. The answer to your second question is no.
@@schrodingerscat7218 Cool.
Can we get the notes in PDF sir
It would have been really awesome if you supplemented the video with the document file in the description.

@@DietterichLabs you can put the TH-cam link in the document and share. That would be better. People will eventually come to the video
@@DietterichLabs so your goal is not sharing knowledge? Instead gaining views?

Thanks!
Pls can you forward me the pdf
