To whom it may concern:

Please, leave a certain user alone that used to regularly post on Physics Stack Exchange. Stop whining and crying about it, and act your chronological rather than your social age. The site is doing just fine without him, and new stars will always appear to replace the old ones. The site is meant for users of all levels from highschool to research level, so it's not being downgraded at all--unless you want it to be a physics equivalent of Math Over Flow.

If you find the place too painful and unhealthy then just leave. No one particularly cares about you, anymore than they do about me or anyone else. It's just a place where people can ask and answer physics questions.

OK? Good. May your time be filled with lashings of physics, topped with more physics delights. Have a nice day :)

comment Is there an analogue of a geodesic for the evolution of the electromagnetic field?
Yes, you can derive the first expression from a particle following a geodesic, so is it possible to do the same with the second expression? Is there a geodesic associated with the configuration space of the electromagnetic field?

comment Is there an analogue of a geodesic for the evolution of the electromagnetic field?
@JohnRennie that question is asking if electromagnetic forces affect space-time like gravity, causing particles to follow geodesics. I'm asking about the evolution of the electromagnetic fields themselves, not the particles affected by them.

comment Does the action and Lagrangian have identical symmetries and conserved quantities?
Thanks! I'll leave you to point this out as a comment to Josh's answer when you get your 50 rep, bearing in mind also that Noether only considered one dimensional curves in her paper.

comment What's the interpretation of Feynman's picture proof of Noether's Theorem?
-1: for stationary action, the start and end times remain fixed, and Feynman requires the distance travelled along paths AB and CD to be exactly the same, which means the velocites along AC and BD can't be finite

comment Veritasium - Firing bullet in block - along center and away from center
The system also needs to conserve angular momentum, so you can also get the final angular momentum about the center of mass.
