Einstein was in academia. He published in the professional scientific literature of his time. He was an academic that also worked as a...

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...

5 M frames per sec is not fast enough to capture the wave that travels down the wire starting from the switch, which takes just about a...

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...

Lasers. Quantum Computing. Semiconductors.

It's not a "holier than thou attitude", it's a true reality. That's not what I said. I said "near zero". It's certainly possible (not...

There's really no way around the fact that the barrier to entry (being educated in physics) is required for practical reasons. There's...

There are a lot of reasons to doubt that FRBs are deliberately engineered and fabricated. But their application for radar is especially...

These specifications like glide ratio, climb rate, etc. all assume you are operating the aircraft to maximize that particular...

I've never, ever seen any serious engineering work where just (school) education would suffice. It's always a long ride along senior...

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...

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

Screw two nuts lightly together near the top. Put a wrench on the top one when you try to turn the butterfly fastener and it should bite...

The reasoning is: A flat blade screwdriver is not the best for applying torque. You need a temporary head on the threaded fastener, to...
