Ever heard of Corvin Amendment (approved by Lincoln!) which would preserve slavery in states where it was legal? https://en.wikipedia.org/wiki/...

Basically it was offer to the South to keeep their slaves, if only they would not leave the Union!

They still fought the war to leave, so it was not "all about slavery", more about tariffs.

If you pay for anything you mention in pre-1965 90% silver coins, it would end up staying the same.
0.715 ozt of silver per $1 back then is $11.37 today ($15.90/ozt spot price).

Here is your 11x dollar devaluation since it got off silver standard.

Well, CRT face is (weakly) grounded, so e- kinetic energy can excite atom for subsequent photon emission, but its charge will happily leak into the ground.

There is no "ground" anywhere next to flying spacecraft!

Actually, on reading the preprint, yes, electrons come from under the Fermi level, get lost in the process and graphene foam (or, spacecraft carrying it) *will* become charged -- it was pointed out in the article as well, but I did miss it on quick read.

AC below actually paints a rather dramatic picture of what can happen next! :)

Where the heck those extra electrons came from? Absorbing photon momentum (more efficient solar sail) sounds feasible, but "accumulating electrons" from nowhere and then emitting them in one direction (where light came from) ... less so.

Your comment made my day! :)

It does not have to be a one-turn coil, 350 turns would require only a MA of current, or only about 10000 times more than a big car starter motor uses! :)

I can not see how this is a valid argument -- of course such data should be anonymized and not traceable to an *individual* patient (this is where privacy kicks in), but it is done in publicly published medical research anyway ("Patient A [not Sam Smith!] was responding to treatment... ").

As to temperature data -- if there is suspicion that it is tainted by "local political concerns" -- should we even consider it to be valid *scientific* data?

Paul B.

Just partially kidding...

My first though without even reading the summary:

Of course pointing it to the South would "catch" more integrated spectrum, but not all of that can be converted to electricity efficiently (they are more efficient for longer wavelength), so it should not *hurt* much to till them westwards (or eastwards), where/when blue light ("useless for") is filtered by the atmosphere...

By the way, blue light is still absorbed/heats/damages the cells, but not gets converted to voltage. Or some such... ;-)

Aligning with peak demand might make more sense though.

There is a reason we have two ears -- to be able to distinguish the direction the sound is coming from!

But it is not actively clicking and listening to the echo (though probably it would work much worse for a blind person who is also deaf on one ear!)...

Remind me to start a company specialising in generating 3D CAD models of custom dildos! :)

By the way, have they figured out how to print softer, rubber-like materials yet? I have an idea of a sister company too...

I would say that an entity that managed to get there and posess some mined material up the Earth gravity well can probably deal with attempts to de-legalize it rather efficiently. ;-)
