But you asked about the convergence of engineering and physics. Engineering is nearly always about devices. Otherwise you'll be stuck with purely theoretical physics, which is really different than the physics most people end up doing. There aren't too many jobs out there without the engineering...

Yes, that works for me. But the charges inside the wire (the waveguide part) are also involved. Ultimately it's a bit too complex to be described by simple phrases. There are some good Veritasium videos about this.

If you have a narrow resolution bandwidth you can use that to convert the spectral density into a voltage. You can assume the psd is flat and just multiply by the measurement BW squared sqrt(BW). Of course the BW measured may only be part of the time domain signal. For a more complex situation...

Lasers. Quantum Computing. Semiconductors.

These specifications like glide ratio, climb rate, etc. all assume you are operating the aircraft to maximize that particular performance metric or, like fuel burn rate, they have specified operating parameters. You can always make it worse, but usually not better.

I used to. The security issues mentioned would depend entirely on what your role is at the company. They employ a whole bunch of people, many of whom don't have any sensitive information. The simple fact that you work there really doesn't matter much. Anyway, I don't know what you are really...

A Dremel tool and an hour of patience. Yes, this is the last resort. I'll bet it's unnecessary.

1) Liquid wrench, or an equivalent penetrating oil (WD40 isn't one, but it's not a bad second choice), while you're reading our comments. 2) Everything @Baluncore said. 3) If you have an impact driver and a deep well socket, that would be a good approach. Align the two stop nuts as described...

Same at Caltech in the late 1970s, but I think EM was just Jackson.

Yes, our first step in troubleshooting PCBs was always a careful visual inspection. It will be obvious if a wire was supposed to be there. You would also have had a dangling wire, which is an unlikely design feature. Plus, it's in your hand, now's the time to see what else isn't quite right...

Or it might not. Here's a troubleshooting tip. If a device used to work but now doesn't, and it didn't ever have a wire attached to a specific point, you probably can't fix it by adding a wire that never was.

Oh, now I get it. I thought it was the long seams. Duh. I hereby completely rescind everything I said about tape. That would be nearly impossible to apply. How about a dollop of caulking applied to each screw head. Maybe with a caulking gun fashioned with an extra, extra long nozzle (after...

That's one reason I like my butyl tape idea. At least the edges will be straight (sort of). Still, if you're really careful with the roller, goop could look OK. I guess you could try clear silicone sealant at the seams from the bottom. I'm really not a big fan of silicon RTVs with any kind of...

Also, I kind of skipped over your point that some users force the underline by formatting their fonts. I guess that's a pretty good user workaround when you aren't in control. Still it is a slight PITA for the typist.

Oops! Now I think I do this too much. Thanks for the tip. It could be like this: Hyperlink formatting information (https://webaim.org/techniques/hypertext/link_text) is on the web. Or this: Hyperlink formatting information (link here) is on the web. For the really long ones. Which is...
