Rrenormalize reacted to Meir Achuz's post in the thread Undergrad Does a Point Charge in Classical Electromagnetism Possess Self Energy? with
Haha.
Of course, I mistyped. It should have been, it IS there by absence. I did write, "This PDF shows that a point charge in classical... -
Rrenormalize replied to the thread Undergrad Does a Point Charge in Classical Electromagnetism Possess Self Energy?.Yet the very first sentence of your original post was: which contradicts the Feynman lecture I quoted and is clearly wrong. Are you...

Rrenormalize reacted to Kick-Stand's post in the thread Product of two boosts and then two inverse boosts is rotation matrix with
Like.
So only after Taylor expanding ##\gamma_v, v\gamma_v, \gamma_w, w\gamma_w## for ##v,w\ll 1## and only keeping terms up to second order... -
Rrenormalize replied to the thread Undergrad Does a Point Charge in Classical Electromagnetism Possess Self Energy?.What Jackson says there regarding discrete charge distributions is (my emphasis added): So the self-energy terms are there in principle...
-
Rrenormalize replied to the thread Undergrad Does a Point Charge in Classical Electromagnetism Possess Self Energy?.Absolutely. From Jackson, Classical Electrodynamics 2nd ed. pg. 28 (emphasis added by me): So by definition, the electrostatic field...

Rrenormalize replied to the thread Undergrad Does a Point Charge in Classical Electromagnetism Possess Self Energy?.Can you please clarify the citation by providing the author, title and page number of the text where this quotation appears? Thanks!
-
Rrenormalize replied to the thread Undergrad Does a Point Charge in Classical Electromagnetism Possess Self Energy?.In your attachment you assert: This is certainly true for a point "test charge" with infinitesimal ##q\,##, which by assumption does...

Rrenormalize reacted to Dale's post in the thread Undergrad A question about the origin of Coulomb's law and point charge divergence with
Like.
The phenomenological fit is something that should be demonstrated in the publication! We cannot help you with any part of the... -
Rrenormalize replied to the thread Undergrad A question about the origin of Coulomb's law and point charge divergence.How does this formula compare to the well-verified results from QED? In particular, where does Planck's constant ##h## enter it?
-
Rrenormalize replied to the thread Undergrad A question about the origin of Coulomb's law and point charge divergence.It's apparently hard to separate the possible structure of the electron from the characteristics of the EM field surrounding it. You...

Rrenormalize replied to the thread Undergrad A question about the origin of Coulomb's law and point charge divergence.How about non-linear electrodynamics? https://en.wikipedia.org/wiki/Born%E2%80%93Infeld_model
-
Rrenormalize replied to the thread Undergrad Can (ordo) Fermions convert to Bosons?.Can you explain what you mean by "(t)he system quantum state is conserved" and in what sense "photons are compressible"?
-
Rrenormalize replied to the thread On Progress Toward AGI.You state that "intelligence is based in incomplete, multi-valued logic from the get go". Is that simply an assertion or can you cite a...
