I'm not talking about fuel that you need to get back, we're still at the "leaving Earth" case. The point is that you need, say, 1000 tons of fuel to leave the Earth. Your rocket then will weigh [weight of empty rocket] +

The first goals of Starship are putting a human on the Moon (this is what the US government is paying SpaceX for) and decreasing cost-to-orbit (primarily for SpaceX's own use with Starlink). Falcon 9 simply can't fly to the moon,

That was in response to the argument that I believe the GP was making by bringing into discussion this timeline. The typical way this is presented by adherents of Zionism is something like "the Jewish people are the original people who

While both sides have been engaged in crimes against humanity, only one is engaged in a violent occupation, by any stretch of the imagination.

No, not genetics, but heritage is a valid, and very commonly used, criterion. I.e., the following is, I believe, a reasonable argument: "I should have a right to live in this general patch of land, since my grand-parents lived here. Ma

The 2-3000 years of history are entirely and wholly irrelevant. Especially as history shows clearly that the Palestinians are just as much the descendants of the ancient Israelites as the Jewish diaspora that returned to their modern land a

They are almost entirely unrelated. When trying to leave the gravity well of a planet, the atmosphere is only a dragging force acting to reduce your thrust. It might be proportional to the surface area of the vehicle, but likely not - I thi

While there used to be resistance to coming up with new formal systems that played with loosening certain restrictions in long-used systems, I think this has not been true for a long time. If you want to come up with a new set of axioms of

I don't think trusting the Lean kernel is enough: you also need to trust that all of the Lean code is a valid translation of the informal proof. Given that the informal proof is already gigantic, and that there is no general mechanical

I think Linus Torvalds has been very explicit that he believes the GPL has been critical to the success of Linux - specifically, the copyright-enforced obligation to contribute back any modifications you make. In a world without copyright,

English also shows a remarkable variation in pronunciation of words even for a single person. I don't know of any other language where, even in careful formal speech, words can just change pronunciation drastically based on emphasis. F

I'm pretty sure even in the USA, you could still be held liable for breach of contract, if you made representations to your customers that you wouldn't share data under any circumstance. The fact that you made a promise you obviou

The point is not about superseding the law. The point is that if your company privacy policy says "we will not divulge this data to 3rd parties under any circumstance", and later they are served with a warrant to divulge that data

This is like claiming that there are fewer people who work in construction now than in the year 1000 because a machine can do what it would have literally taken 100 people to accomplish back then. But what has happened instead is that we ar

If I can build something in 100 hours paying 100$/hour, or 33 hours paying 400$/hour, I may well choose the 100 hours version. Which is why we hire interns in the first place, rather than only hiring senior architects for our comp

While I agree with the gist of your argument, you should also note that "organizations that hire outside consultancies for urgent issues" is a self-selecting set of orgs with terrible coding practices. There are probably many more

None of this matches the setup the paper describes, though of course you are right that bleeding heat into the Earth is a time-tested and known to function way to build such systems.

Sure, but then the temperature of the object has to increase. And as its temperature increases, it has to stop condensing water - at the very least, once it reaches ~100C, it will instantly boil off any extra water that it condenses.

Except we know that is impossible from simple thermodynamics, so there's no point in contemplating this "what if".

There is no way to make a passive, solid-state humidifier that doesn't involve some chemical reaction with water. Thermodynamics dictates that precipitating water from a non-saturated atmosphere must generate large amounts of heat (ass

So, is this new method less noisy and/or more energy efficient? The article doesn't really say.

Those exist, but, as the GP points out, they're called "dehumidifiers". Or sometimes clothes driers. The question was, what makes this new dehumidifier any better than existing dehumidifiers.
