I think one difficulty would be that the salt would not drop back into the ocean. As each droplet progressively evaporated and shrank, the salt would become more and more concentrated, leading eventually to tiny particles of salt that would be carried inland by the breeze for long distances. I would propose instead to combine your idea with solar stills to generate fresh water for your pumps, returning brine to the ocean. In such hot deserts, one almost invariably gets a daily onshore breeze after about 11am, due to the rising of hot air over over the desert drawing in cooler air from above the sea. This normally persists until just before sunset. So it would be a fairly reliable process, I think. But I have no idea whether enough evaporation could be achieved to change the climate this way. I think I read some years ago that another way is simply to use the fresh water for irrigation and promote the growth of plants which, by their transpiration, start to alter the climate that way - and generate moisture-retentive soil, by the detritus on the ground that they create.

A controlled application of the strong nuclear strong interaction would be a nuclear power station or the nuclear bomb. I rather think the weak interaction is also involved, along the way. I can't think of a controlled application of the weak interaction on its own, though. A controlled application of gravity could be a clock pendulum or the weight mechanism of a grandfather clock.

While it is true that UV does eventually weaken fabrics, this is usually noticeable only for things such as curtains and sofas that may be exposed to a lot of direct sunlight for hours every day, for years on end. For clothes and bed linen, i.e. the items on your washing line, you can usually ignore this, as the exposure time is a few hours per week at most. Most clothes wear out for other reasons. Regarding dryers, it is noticeable that a significant amount of fluff collects on the filter of a dryer every time you run it. This is no doubt partly human skin cells, but a lot is fibres from the fabric. My guess would be this will have more of a weakening effect than sunlight on a clothes line. In my opinion, clothes dried outside smell fresher - and of course it is more environmentally friendly as well. So personally I always dry clothes outside, when the weather permits. I make an exception for towels, which are much softer if dried in a dryer.

But there is friction in the oceans, in the tidal currents. This is spinning the earth down. However, angular momentum is a conserved quantity, so if one part of a system spins down due to friction, something else has to gain the angular momentum lost. In this case it is the moon, which is moving to a higher orbit - getting farther away - as a result.

OK. What do you think will be the mass of 0.1 moles of it?

What is the object of this exercise?

What's a "public towel" and why would anyone rub their genitals on one?

Yes, "a theoretical heatless pseudo-infinite energy source using bullshit and rapid spatial expansion" sounds far more rooted in the real world to me.😄

Looks to me as if “ blueshift” may have been a typo for “bullshit”.

Yes of course but so what? We know what effects are to be expected due to gravitational attraction. Massive bodies attract one another. But at level of individual atoms the effect is negligible and totally overridden by other interactions, chiefly electromagnetic.

"Nein." (W. Heisenberg)

Oh I see what you mean. The gravity actually at the surface will have lateral components, due to the fact the mass is not all lined up beneath one's feet, whereas as one climbs higher above the surface the force increasingly becomes all orientated downwards. So yes, I can now see that a more diffuse mass will have weaker surface gravity than a more concentrated body of the same mass. So, given that, at a large distance above the surface the gravity from both would tend toward the same value, that would imply the gravity falls off more slowly with the diffuse body than the more compact one.

Sure. But then that's just the way of the world generally: success has many fathers, but failure is an orphan. The important thing is to have a system that is effective. In my opinion, one of the most dangerous trends in modern politics is the belittling of expertise. "We've had enough of experts" is the road to ruin - as we can see around us.

This is the argument for offloading this sort of highly technical supervision to an independent regulator, whose office is composed of long term professionals and who can come to the legislators from time to time with requests for legislation to help enforcement as required. The problem then is the "small government" politicians will moan about "unelected bureaucrats" , when the whole point is to get people who are NOT elected to do the job, so that some degree of professional expertise can be brought to bear.

Does it? Surely it depends only on the the planet’s mass, per Newton’s law?

So, then, is the thread topic just that politicians have to deal with all the real issues? If so, I'm not sure that's true. "To govern is to choose", after all. They can't do everything all at once and they can't be everything to everyone.

So, nothing better than YouTube videos, eh? Wake me up when you have something worth discussing.

This seems on the face of it a very odd claim. Can you give some context or, best of all, refer us to a source or an internet link, in case that helps understand what is meant?

With all due respect that is a quite different issue from the one described in the BBC article that you linked in the OP. That BBC article is about people's addresses being falsely used as the legal registered company address, by scam companies. What you are now talking about is just one of the numerous internet scams, involving impersonation of a service provider in order to scam people. The scale of these scams is indeed shocking and well worthy of attracting far more vigorous action by law enforcement than it has received up to now. But it has nothing to do with Company registration or the operation of Companies House.

I read this. But what I can't see, from the report, is why it matters very much. OK so these people get some mail they have to return to sender. But that's about it, isn't it? They are not held liable for anything, just because their address has been used. There's nothing here to suggest they have suffered any loss as a result.

They are, but they also have an amine group.

No. A white surface reflects more incident radiation, but once the radiation has been absorbed by the black surface it is not transmitted through the material by radiation any more, but by intermolecular collisions, so colour is no longer relevant.

This looks like homework. What do you think happens, and why?

It just means that intellectual disciplines are a bit more complicated to master than sport, doesn't it? Why would everything be the same, just because some klutz pulls a "rule" out of his arse?

It seems there have been studies on this: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4881732/ Fumes from hot oil are not combustion products, but they do contain a lot of species chemically altered by heat -by thermal cracking, in effect. There are some details in the link, though that study was mainly concerned with the epidemiology of lung cancers.
