I take this as a positive sign that the administration expects elections to continue... and that's where we're at.

I think I'm missing the part of that article that supports that.

I strongly suspect Russia doesn't intend for Ukraine to be around for a generation to come. Admirable work by Ukraine, however. Hopefully they can continue to disappoint Russian intentions.

This setup might be impractical for field use, due to the bulk of the interferometers and the requirement for sensitive calibration, but for your purposes it should be suitable.

You'd shown a Michaelson interferometer, but you might have better luck with a Mach-Zender interferometer.

If the beams are not too tightly grouped, and your target is in the right frequency range (not too low, not too high!) you could even calculate your target's position inside a room and filter to listen to exactly that source. This can all be done on recorded signal; doesn't have to be live.

If you are feeling especially ambitious, you could split your source beam into 3-4 tightly grouped, parallel sources and catch those with 3-4 interferometers, which would allow you to filter out vibrations in the plane of the mirror.

If you still have your lidar sensor, placing this near your interferometer's source laser and aiming it at the same surface could help you calculate where to look for the specular bounce. It'll get you both the distance to the surface and the normal of the surface!

Your plan was to do interferometry next, and I think that's absolutely the right direction. You should look into "quadrature interferometry" which doubles the resolution and adds direction to the displacement of your surface. Very useful for filtering noise!

People are complex, and we do ourselves a disservice by reducing them to simple representations, as gratifying as that might be sometimes.

"A shutdown would cause more chaos, and that would be worse". It's also one of the few ways to hold a would-be dictator accountable and put pressure on him to govern responsibly. If you want the chaos and consolidation of power to stop, you need to be willing to endure some chaos in the short-term.

Previous literature has determined that this partisanship effect disappears when subjects are given a financial incentive for identifying disinformation accurately.

The problem is that any Jedi living up to their reputation is necessarily an unbearably boring character. Aspirationally, it's a very dry and uninteresting order.
