Comment Re: ballistic decay (Score 3, Informative) 33

A contradiction in terms, since something ballistic is implied to be acted on only by gravity and will not decay.

There is something called the "ballistic coefficient" (bstar in TLE speak) that, while also a contradiction in terms, refers to the drag coefficient multipled by the area-to-mass ratio of the object in orbit.

The decay of an object in the lower reaches of low earth orbit is dictated by the product of atmospheric density with the ballistic coefficient. A dense brick will last longer than a large sail of the same mass in the same orbit.

"Ballistic decay" is the above simplification simplified further by the well-known phb method.

If they're lower, they're *less* intrusive to optical telescopes. Lower altitude means they're sunlit over your head while it's dark enough for astronomy for a *shorter* time.

In the extreme case, a geostationary satellite is almost always sunlit all night long from anywhere on the planet.

The Moon is sunlit almost all the time except during a rare event called a lunar eclipse.

The higher the orbit, the larger the fraction of it that's outside the earth's shadow.

No congressional auth on that one either.

Either amend the constitution and live with the real possibility of a hobbled military response time in an emergency or win the argument at the ballot box.

Not sure congress and 3/4 of the states actually feel strongly enough about Maduro or Assad or whatever else had been going on on the DL the last few decades to actually push for an amendment.

Would be a lot easier to win the argument at the ballot box if your party isn't saddled with the baggage of its cultural extremism around its neck.

As I've said before, I'm neither for nor against this stuff in Venezuela on principle. Maduro and co were clearly not the good guys. Also clearly, Rubio is the driving impetus here, and my only statement is that I expect there to be a plan here that's more thought through than Iraq was.

If it's mostly subsistence agriculture, I would think it's logically a little hard to draw the distinction between work and not work in the sense of punching the clock and kicking back after 5.

I'm willing to be corrected here, but I'd assume back in 1830 is farmer bob and fam worked the soil so they could eat 70 hours a week and sold maybe a 10% surplus at market, they had a 7 hour work week.

If AI makes people more productive, it would stand to reason that it would create more wealth with the same amount of effort.

In such an environment, what exactly would be the incentive to work less given that you can get more from working the same?

Mechanization didn't shorten the work week. Automation didn't shorten the work week.

Why would AI be different?

No. Back in the Soviet days, we were all equally poor, except for the few animals who were more equal than the others.

Regular power and water cuts. Party line telephones (in a major city in 1989). Persistent shortages of one kind of foodstuff or another (retirees lining up at the state run dairy store at 5am to get their share before it ran out). Nearly decade-long waiting lists for automobiles and furniture.

We came here when I was 7 in the early 90s. Our first place here was an apartment across the street from a supermarket in Philadelphia. We went a day or two after we settled in and I'd never seen my mothers jaw drop so low when she saw all the food just there for purchase.

But equality!
