On a tangentially related note. (and I accept, it's a serious "tangent"), if I was minded to repeat Cavendish's experiment on weighing the Earth, What would be the best material from which to make the suspension wire?

Lead is hardly the only possible contaminant which would have people wearing masks etc. Have we ruled out asbestos, for example? By whom?

Could a combination of materials do for a piano frame what this does for the pendulum of a clock? https://en.wikipedia.org/wiki/Gridiron_pendulum Even better, could it change the length of the frame in such a way as to compensate for changes in both the length and the tension of the strings? That way, temperature wouldn't affect the tuning. The old joke about "it was in tune when I bought it" might become a thing of the past.

OK, so people seem to be saying that because the lead fell down and polluted the floor, it went up and polluted the sky. OK...

Can you cite examples, or have you made that up?

You can have photon emission noise too if you need a third option.

LOL If, in spite of the rules, you are going to call people stupid, at least get the grammar right. A lot of things, including the use of apostrophes.

If the question is "hwy don't proteins form perfect crystals" then the answer is "The same reason other things don't; the laws of thermodynamics". There's nothing special about proteins in this regard.

Practically no crystals are prefect. Proteins, and even entire viruses can form pretty good crystals. https://www.jstor.org/stable/231608?seq=1#page_scan_tab_contents So the opening post makes no sense. It's like saying " how come we can't build brick walls/" Andyet, rather than saying - "we can build them", people don't bother to check. They draw up elaborate explanations for things that are not actually true. Hence my questions Why do people insist on trying to explain things that don't actually happen ? Why do people insist on trying to explain why things that do happen, can't happen?

If it was completely Earth like, it would have completely Earth like temperatures.

This reminds me of the old joke about the boy who says he can't go to school because he's too busy. You know the one... There are 356 days in the year. But 104 of them are at weekends and there's no school then That leaves 365- 104 i.e. 252 days And I'm asleep for 8 hrs a day so that's a third of the time which is another 122 days. That only leaves 130 days. And so on... It adds up to an unreasonable total. And the reason it's silly is that he's double counting. It doesn't take account of the fact that you sleep at weekends etc. And the OP here is so enthusiastic about his point that he's overlooked all the double counting. For a start he's got factory workers and office workers on the list twice. (items 6,7 and 28,29 if I counted right) And then there's the fact that "office workers" and "factory workers" are typically in one or more of tehotehr groups. e.g.maintenance workers, other skilled people and blue collar workers, maintenance workers and so on are likely to be factory workers.

The use of "not once" is unhelpfully ambiguous. Do you mean zero times- which is "not once" or do you mean many times which of course is also "not once"?

The easy way is to sacrifice safety.

Have we ruled out trolling as the cause of the problem? Anyway, it seems that nearly everything can change- everything except Farid's mind.

If you are inside a conductor- like your power line workers- the pattern of voltages in the outside world can do as it pleases. None of them will affect you. They may induce currents in the suit when they change. In particular, no DC arrangement of potentials fields, or voltages outside the conductor will affect you if you are inside it. That's the sense in which a Faraday cage works just fine for DC and the sense in which the thing you're sure of is wrong. You were simply mistaken. It would have been better if you had asked for help, but you went off on some daft tangent about Now, what was that about rhetoric?

OK, fair point. I should have read it more carefully. However there's still a difference. An army of people have been trying very hard to find problems with GR- and they have not. (Not yet, if you insist) They have made measurements to lots of significant figures and GR seems to work. So, to the best of our (current) knowledge, GR gives the right answer. So, (to the best of our current understanding )anything that disagrees with GR by more than the tiny experimental uncertainty is wrong. So either those early papers agree, or they disagree by some tiny discrepancy, or they are wrong. In which case the answer to the OP's question is "they are subsumed (if they are right) or superseded (if they are wrong) or the difference is so small that we can't measure it"

So, when I address the dog from the Magic Roundabout, I risk having my message listened to by Google. What are the chances of that actually telling Google anything "interesting"? OK Dougal? https://en.wikipedia.org/wiki/Dougal_and_the_Blue_Cat

Cannabis is not typically considered a stimulant- rather the reverse. So, if your assertion is correct (and others have already questioned that) it suggests that bright people seek downers as much as uppers, so it's not necessarily stimulation they seek.

No. If I posted something like I'd still be criticised for being wrong. OK, here is some information that may be useful to people working in conductive suits on high voltage systems. Make sure that any holes in the suit are small. The exact definition of "small" depends on context. In the particular case of a hole with a wire running through it the value tends to zero. Because, in the case of a "faraday cage" with a wire leading through a hole in it, you don't have a faraday cage.

Still wrong.

At that time, the precession of Mercury would mean that the important first statement in the set "We know that GR has passed every test that it has ever been subject to." was untrue of Newtonian physics. And you seem to have missed the significance of my last conjecture.

To be fair, I strongly suspect that English is not Farid's first language.

Does wiki say this a Faraday cage only blocks changing fields, not constant voltage ?
