bhobba replied to the thread Intro: 18yo Physics enthusiast.Indeed welcome. Hang around, and you will be surprised by what you learn. Thanks Bill -
Welcome, Okabe.

Welcome Okabe. I read your post about QM (though I have no answers for you). I've asked the moderators to update the thread title to...

Hello everyone! I am an 18-year-old student from Delhi, India, currently waiting for my Class 12 board results. I've been doing a lot of...

bhobba replied to the thread Seeking clarity on the physical definition of an observer.It is surprising how much of what we discuss is, to a large extent, semantics. I know we don't discuss philosophy here, but many of...

Haha.
Is that like the difference between all dead and mostly dead? -
bhobba replied to the thread Seeking clarity on the physical definition of an observer.As an 18-year-old, QED has been suggested as a good place to start (and I agree). The following video suggests the next books to read...

Regarding questions 2 and 3, one suggestion is to read Feynman's book on QED:The Strange Theory of Light and Matter. It doesn't cover...

bhobba reacted to Paul Colby's post in the thread Graduate Gauge conditions in interaction theory with Like.
One is always free to change gauges. One is not free to violate charge conservation. Beyond that, I have no idea what you’re trying to...

I think you're missing Paul Colby's point. The EM field equations only make sense in the first place if the current ##J^\mu## satisfies...

The EOM you quote conserve charge, ##\partial_\mu J^\mu =0##. You then violate charge conservation with your assumption, ##K^\mu =...

Skeptical.
Inside of an atom the electron and proton are tightly packed together making thier magnetic fields more powerful while inside of a... -

Can you cite a credible textbook reference that supports those claims?

bhobba reacted to akhmeteli's post in the thread Undergrad On computing quantum waves exactly from classical action with Like.
Hossenfelder has blogged about the article, called it mathematically erroneous (actually, she was somewhat blunter :smile: ).
