What will happen at some point is that sites that require age verification will require some kind of verifiable token generate by the OS-level age verification. Rather than the myriad proliferating independent age verfication. But it's a legislative ratchet that is unlikely to move in the opposite direction. If you don't want OS level age verification, then likely you'll be confined to the part of the internet that doesn't require age verification.

Your assignment: Find out why reusable rockets are only useable for very specific launch envelopes. If you use them out of that launch envelope, there are just as disposable as the rockets you think are some sort of complete waste.

Interesting. I've never seen this claim made before; do you have a reference?

https://www.teslarati.com/spac... Forgive the link, it is a real rah-rah piece.

CEO Elon Musk says SpaceX has successfully expanded the envelope of orbital-class rocket recovery with its 50th booster landing, meaning that all Falcon boosters will have a better chance of safely returning to Earth from now on.

https://space-offshore.com/boo...
"Falcon 9 missions may need to land on a droneship instead of RTLS due to the weight of the payload or the overall mission profile."

I think you have academic access. Here is a good technical report on a lot of rockets that land after use. https://www.sciencedirect.com/.... You'll need academic credentials to download it. But it has a lot more info - and as part of the launch envelopes, there is constraint based on payload as well as direction. If you are going to land, there is a significant reduction in payload.

Looks interesting, I'll take a look when I get back in to work.

Comment Fluid versus crystallized (Score 2) 124

I think what is really going on is that is not 'fluid IQ', but regular, normal "IQ".

"Fluid" intelligence is the ability to think, reason, solve problems, and learn things. "Crystallized" intelligence is your amassed knowledge.

These are technical terms used in the literature.

Intelligence is nature's guess as to how complex your environment will be... but there's an out. People with low fluid intelligence have to work harder to understand things, but if they put in the work they can amass a body of knowledge that rivals that of people with high fluid intelligence.

And of course, lots of people with high intelligence stop learning in their mid twenties. At that point they've conquered their environment and are living successful lives (good job, married, kids &c) so there's no real reason to push themselves. Lots and lots of people, even smart people, haven't read a single book in the last year - and this observation was true in the 1970's before the internet.

(And nowadays this is probably more accurate due to the appalling quality of information found on the internet.)

That is, stupid people either do not realize the AI is wrong, or more likely, they are so used to being corrected by more intelligent people that they just assume the AI must be smarter than they are and do not challenge it.

It's a question of training. We're evolved to believe what people say, it's a way of reducing the cognitive load of learning things (by believing what someone else has already figured out). We're not used to questioning the logic of someone else's beliefs.

As an example of this, note that Warren Buffet has built a career on identifying fallacies in business, google "Warren Buffet fallacies" for a list.

None of these fallacies is taught in school, everyone has to find them and figure them out on their own. And then you have to use them in your daily lives.

Almost no one is used to doing that, which leads to the current problems with AI.

And yours is a monarchy, with the closest thing to a constitution only being a charter that only guarantees any rights at all to barons and nobles, whose descendants to this day still hold their titles and rights from ages past. The only thing it promises, but does not guarantee to you, is a jury trial. You guys sentenced Markus Meecham to jail and a fine en banc, putting a felony conviction over his head making him unemployable, over a youtube comedy that didn't involve any kind of violence or threats. The only way he makes a living at all is because he's paid by an American company to entertain his viewers.

And for voting...well...you don't even get to vote for your German head of state, who is not just for life, but by birthright to each successive generation he begets. Your prime minister legally only acts in an advisory role, who your king has the power to veto.

Anyway, how is ol' Boris doing?

I think starship is a better bet in the not too long term, and wish he wasn't involved with it.

Unlike you, I'm a strong believer in giving credit where credit is due, regardless of what else I think about whoever it goes to.

Without Elon there's no SpaceX. Full stop. He bet everything on it twice. And unlike you, it hasn't received *any* federal government subsidies either. The ESA, NASA, Rocketlab, Blue Origin, and many others were essentially betting against the idea of reusability, the ESA in particular making fun of the idea in a press statement, and Elon in particular who was the only one in the industry pushing hard for it, not only to the engineers, but investors. The rest is history.

Shit in one hand, wish in the other, and see which one fills up with what you consider to be edible faster.

Comment Re:Source term for Einstein's field equation (Score 1) 55

Your comment has nothing to do with the fact that mass is explicitly part of the source term in Einstein's field equations.

I'm not sure why you'd say this.

I'm saying this because mass is part of the source term of the Einstein field equations. Are you being deliberately obtuse because you want to extend this meaningless conversation infinitely long despite the lack of any content here?

You claim the T00 term is mass density, and seem to be claiming specifically that it is invariant mass density,

Huh? No, rho/c is just one term of the tensor. If you want it in some other frame, you can't just take one term out of a tensor, you have to use the full tensor.

If you label the T00 term energy density, it's not invariant either. One term out of a tensor is not invariant no matter what you label you put on it.

...
Mass is not a *fundamental* source for gravity.

Correct. The stress-energy tensor is the fundamental source for gravity. Which mass is a part of.

Correct. And you plug it in as the 00 term in the stress energy tensor.

I don't know what you think those quotes means, but I don't think either one is denying the existence of mass, nor saying that mass is not a source of gravity.
