  1. I’d think that reasonable so long as you did not throw or drop the thing suddenly. It seems to me one has to think in terms of something like a chip pan fire.
  2. I've read through it and I repeat there is no thought experiment anywhere in it. It's a rambling muddle of sciency words, thrown together at random, for instance: - "The natural tendency for a hydrogen C-atom is to make a perfect sphere. As a single cavitation (C) on a single singularity its inherent tendencies to make it's photon and corresponding electron-shell at the different times of the bounding wave are very simple." Or "If that wasn't hard enough to waddle through.. lets call the hydrogen C-atom's want of a perfect sphere it's 'true' shape and the effect the affect of the warpage has on it as it's 'apparent' shape. Why? Because there is a difference when it comes to buoyancy only existing in gravity. Harmonic bonds that perpetually reshape the energy forms bonded between local elements and molecules, aka anti-gravity in a solid aether." WTF? I'm sorry but this is a waste of everyone's time.
  3. I'd have thought anything that breaches containment of the electrolyte might well cause a very rapid flare-up, even if not technically an explosion.
  4. My limited understanding is that at high temperatures some of the components actually evolve oxygen, so the thing cannot be smothered. The only way to stop it seems to be either to let it burn out somewhere where it can't damage anything else, or to use copious amounts of water, sufficient to cool it enough to stop the further evolution of oxygen. At least, that is what I have read somewhere the fire brigade tries to do.
  5. No it is not a thought experiment. A thought experiment lays out a particular physical scenario in detail, to illustrate how a hypothesis or theory can be applied to a real situation, or else to derive a hypothesis from it. There is nothing remotely resembling that in what you have posted.
  6. What thought experiment?

    Is this the entire structure made on-site, or sections made in a factory that are them moved to the site for assembly? If the latter, the structure required to enable the pouring of concrete to the 3D printer pattern must be humungous. I would expect it to be very costly and time-consuming to erect for each house. I presume this technique can't be used for reinforced concrete. I wonder what they do to achieve an aesthetically acceptable surface finish. I don't imagine the ribbed surface will be very attractive. Though I suppose the grooves will retain moisture and may promote growth of moss and so on. So may they look quite green and "eco" after 10 years or so.

    I can't visualise that. Is there a link or a picture? Must admit I've never understood 3D printing.
  9. Quite so.
  10. You didn't write that. The style - and the obsequious opening - are quite at odds with your own. You are quoting some other source, without attribution. You have done this before, introducing egregious errors in the process.
  11. This is a nice example of why you pick up downvotes.
  12. A more self-aware person might be asking themselves why. But then, a more self-aware, or more socially adroit, person would probably not have accumulated so many downvotes so rapidly.
  13. I’m afraid this is word salad: https://en.wikipedia.org/wiki/Word_salad

    My last visit to McDs would have been in 1999-2000, when I was working in Houston TX and on a road trip with colleagues. I married a French woman, you see. 😄 Regarding the story about the original Mr. MacDonald, I’m not surprised. Plenty of people don’t have the energy, or the drive, or the greed, and don’t want the aggro. We should value such people more, I feel. They have something valuable to teach us.
  15. Accusing people who don't express interest of being "afraid" is classic crank boilerplate. So 20 crank points for that. Also I note the riot of fonts and colours, again characteristic of cranks. So 10 more crank points for that. 😁 You never responded to my post in 2021, asking whether all you had done was insert the f-block in between the s and d, which every chemist knows is where it fits. It looks as if, at that time, that indeed was all you had done. Hence nobody thought this was a great revelation or worthy of comment. Now, 3 years later, it seems you have added this little vertical displacement to indicate net unpaired electron spin and talk about Hund's Rules. I don't really see the value in this. It seems to add complexity to no particular purpose. Most chemists are not that much concerned with ground state atomic term symbols, but with how elements react chemically. The unpaired spin in the atomic ground state does not seem to me to yield much insight into the chemical compounds formed by the elements. Or do you think it does?
  16. Yeah but none of those is actually tea. They are infusions that are called “tea” colloquially and for marketing purposes but they are not real tea. The French call them tisanes, but in English we don’t seem to have a name that does them justice.
  17. You've already done this, several times, over the last few years, haven't you? Why do you think we are going to be any more interested this time round?
  18. Yes, it takes longer than a teabag to brew, as the leaves are whole or in big pieces rather than "dust". But then tea is meant to be something relaxing, that you stop what you are doing to enjoy, so a few minutes to get it right should not be an issue. Same general idea as pouring Irish stout, I suppose.
  19. Oh Christ [rhetorical]🙄 I stopped visiting that site because of its toleration of trolling, bad faith argument - and all the monomaniac nutters. This is a haven of rationality by comparison. You may need to up your game here.
  20. Do I know you? I generally avoid having friends who are barking mad🤪😁
  21. There are estimated to be over 2 billions Christians around the world. Are you seriously expecting us to believe that they have been able to hide a “covert” belief like this from themselves and everyone else for 2000 years?

    Today, I learned there is a thing in British lakes and slow-moving rivers called the swan mussel: I was walking yesterday on Wimbledon Common, where there is large lake that has for some months been drained for improvement works. I noticed quite a number of large, elliptical shells in the dry mud bed of the lake and picked one up to examine. The shells are quite thin and light, but large. (The picture is from the internet but is very similar to the one I picked up.) I looked it up on line this morning and was able to identify it. I had no idea there were fresh water molluscs like this in the UK. They are not rare, apparently, but being generally buried in the mud at the bottom, they escape attention. Swan mussel.pages
  23. Loose leaf is indisputably far better tasting. Teabags are commonly filled with what tea packers refer to as "dust", i.e. the bits that break off during the packing leaf tea, e.g. Dust Number 1 and Dust Number 2. Among the leaf teas you can get BOP (broken orange pekoe - smaller) or FOP (flowery orange pekoe-larger). I buy Assam and Darjeeling FOP from these people: https://www.shopdrury.com/drury-leaf-teas/?features_hash= , Assam for body and colour, Darjeeling for aroma, and blend them 50:50, in the teapot. It takes about 3-5minutes to brew. You do have to get the leaves out afterwards into the food waste of course, which takes you a minute or so. One tip: do not try to put tealeaves down the waste disposal unit. We briefly tried that in Houston but the leaves were too small to get chopped up by the unit, yet large and mechanically strong enough to block the pipe!
  24. Really? By now, you should not need to ask. There has been a procession of the most egregiously unqualified people appointed by Trump to every position of importance in government. The reasons have been discussed at length in the media. It is partly that he wants meritless people in these positions who are well aware they owe the position to Trump’s patronage alone. So he can demand personal favours and the departments these apparatchiks control will swing into action: to harass a judge, to investigate the tax status of a university, to question the licence of a broadcaster, to drop a prosecution, or start one, etc. And it is partly delight at trolling the establishment, to rub their noses in the fact that he is in sole charge and there is nothing they can do about it - a display of dominance. Stalin was just the same.
  25. Isn't microplastics from degradation a potential issue - though no idea how serious?
