renormalize's latest activity

I think you meant to write:$$-\frac{\hbar^2}{2 m}\nabla^2\phi_n+V\phi_n=E_n\phi_n$$

I don't see that at all. Consider, e.g., Griffiths & Schroeter, Introduction to Quantum Mechanics (3rd ed.) in which the authors solve...

But elementary physics texts regularly use shorthand terms like "point mass" (not "point object with mass") and "point charge" (not...

Actually, it's another paper by a philosopher discussing quantum physics across 25 pages of dense verbiage and no math whatsoever. Could...

Not yet, here in Italy it was quite bedtime when I saw the email notification of the reply. I will probably write today, but before that...

Hello, I certainly searched (even with Google, that I normally avoid) but I used "lathe" as a search term (since it's the machine that...

Did you do any online searching before posting your question? The first link that comes up for me on Google for the search query...

Sure, but what's your point? Rather than EM energy, the gravitational energy of the big bang is much more likely to have produced the...

Yes, I definitely agree with that statement, since what we now called the "Schwinger effect"...

PS and electromagetic radiation can produce an electron-positron pair. See, for example...

Yes, your reasoning is correct. Take a look at: https://www.soapbubble.dk/en/articles/thin-film-interference which shows a half...

Ah, I did miss something out there. How about, for the last line: Because the power loss from heating in the lines ##P=I^2{R}## ...

Agreed, but also beware of answers that are too "hand-waving" or "dumbed-down". Again, quoting you: But by that logic one could just as...

Sure, but the OP specifically asked: That's the basic question I aimed to answer in my post #9.
