How to derive Maxwell stress-energy tensor

AI Thread Summary
The discussion focuses on deriving the Maxwell stress-energy tensor in a vacuum, emphasizing the role of the Lorentz force in the interaction between mechanical systems and electromagnetic fields. A participant expresses uncertainty about how to begin the derivation after completing relevant chapters in Griffiths Electrodynamics. Another participant suggests reviewing the textbook chapters for guidance. The conversation highlights the importance of understanding the foundational concepts before attempting the derivation. Overall, the thread underscores the need for a solid grasp of the material to tackle complex derivations in electrodynamics.

The problem statement is:

Assuming that we are in vacuum, and that the only work done between mechanical systems and
electricity and magnetism comes from the Lorentz force, give a full, relativistic derivation of the
Maxwell stress-energy tensor.

Can you show us what you know and what you've done so far?

i know the answer should be this

But the question is "how to derive that", our class have finished Griffiths Electrodynamics chapter 12 (relativity in electrodynamics) and now doing chapter 8 (conservation law). I really don't know where to get started.

Well, my hint to you would be read the chapter... there you'll find a lot of help.
 
Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'
(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
