Check your residuals. A third degree polynomial doesn’t look particularly appropriate here.

Latinometrics is almost always about making Latin America look good. It’s a propaganda machine, not a data tool.

What is a space program other than a far future military research division? This research will eventually filter back to military applications and maintains the US hemomgeny.

It’s not really fiction in the library sense. Fiction is designed to be read mostly for pleasure. The bible would most likely end up in a non fiction reference section on religion and/or myth.

Non-fiction generally doesn’t mean “scientifically true”. It’s more about why someone would read a book. Especially down the lower end of the Dewey scale you will find a lot of odd ducks.

Ukraine doesn’t really matter in the negotiations. If the west stops providing Ukraine weapons and ends sanctions on Russia, Russia will win (eventually).

Now this is not going to happen. But it’s worth keeping straight who has the power in these plays.

Or just lag the pipes. Same principal as the electric blanket. Use a little bit of heat in the important places, no need to heat everything.

Yup. Plus Australia and China agreeing on anything these days is good click bait. We’ve been on the outs with China for a while in Australia.

Nope. Two stars close enough to have Oort clouds intersecting will be close enough to be directly orbiting each other. The gravitational weirdness of a binary system will clear out anything in the Oort cloud.

But all is not lost, it’s likely another Oort Cloud will form around the binary system.

I think we should tread carefully on this.

One of the huge advantages of oil extraction is that it has a low land use foot print. Using oil for chemical feedstocks generally doesn’t pump out much carbon (beyond energy use). So at this stage it still seems to be sensible.

On the other hand plant based feedstocks suck up a lot of land. This is land that can no longer be used for food production. Farmers switching land to biofuel was implicated as one of the causes of the 2008/09 food price crisis (although not the major one).

From a technical point it’s generally straight forward to dial up these processes on the factory side. But the land use side is hard to get around.

That’s interesting. We tend to think of Columbine as a watershed moment, however the graph shows otherwise. Guns on school grounds have been an issue for a long time.

On the other hand it also shows that your chances of actually being shot as a student is still minuscule.

While this is true in general terms, its not true for the post I was responding to.

Come on. This is a science sub.

We have never seen a FTL particle, ever. And we have looked for them.

We have no gaps in our theories of physics that would be effectively explained by allowing FTL.

And every known law of physics would turn out to be wrong if FTL was a thing.

None of that suggests that we will ever get to FTL.

Because we like causality.

Faster than light travel plus relativity means time travel. You would literally be able to travel backwards in time. Full on Michael J. Fox fall in love with your mother time travel.

Time travel introduces so many logical paradoxes that most scientists reject it out of hand. Even if you don’t reject it and allow time travel to be a thing, every known law of physics breaks down.

It’s not just a “go faster” thing. The speed of light is a fundamental limit to the universe.

You will always get less energy out of electrolysis in hydrogen than you put in as electricity. That’s how thermodynamics works. There is always waste energy in the form of heat.

So you won’t be saving any energy here.

The basic problem is that the sea water will corrode your electrodes (ie the exposed extension cord wire). On any sort of scale, electrodes become a huge cost and downtime factor. As a result most electrolysis plants use clean water.

Improved electrodes that are resistant to seawater corrosion means that we don’t need to use potable water to produce hydrogen. This is a big deal (if the tech ends up being scalable).

Australia, Canada, NZ, UK, Germany...

The US has some pretty high income inequality for the developed world. While rich Americans are generally doing extremely well, its generally a bad place to be poor.

It’s psychology, so yours is entirely possible. Historical psychological experimentation has been plagued with societal bias. And todays sometimes isn’t much better.

Not at all. There is still plenty of research into complete cures.

But in the meantime there is also opportunities to improve quality of life.

Another possibility is that the cultural contexts pilots came from and existed in changed over those thirty years. Human psychology isn’t a constant.
