  1. No, it doesn't. If you want to discuss statistics that's fine. But starting with a false statement is just going to distract people. This isn't any better.
  2. If it's a detonator, it only needs to work once. So it's a slightly different scenario. But, since it's a detonator, I'm not going to help.
  3. I wonder if there's a geometrical solution.
  4. Seawater is typically slightly alkaline, but poorly buffered. There isn't much in it (apart from salt). So adding small amounts of acids or bases to it will change its pH by a large amount. And, if your red cabbage indicator has much vinegar in it, you will overwhelm the small amount of alkali in the seawater and the mixture will end up acidic.
  5. This is about the best I can think of as a quick way to grow stuff, but it's not the same thing https://en.wikipedia.org/wiki/Chemical_garden In principle, it should be possible to make a system that drives carbonated water through crushed limestone and then let that solution lose CO2/ evaporate and deposit CaCO3.
  6. The tables I posted a link to are for sucrose. Golden syrup is a mixture- it contains quite a lot of invert sugar. Also, you could measure the density; why would you want to?
  7. If I want to find a definition of it I can just Google "define physics" and it will tell me. I can do thr same with biology or chemistry. But those words are longer so, in terms of how many letters I have to type, it is actually easier for me to get a definition of physics. Incidentally,if you are going to garble a joke to make your point, you might as well include the original. “If it squirms, it's biology. If it stinks, it's chemistry. If it doesn't work, it's physics. And if you can't understand it, it's mathematics.” ― Magnus Pyke
  8. Sugar https://www.engineeringtoolbox.com/sugar-solutions-dynamic-viscosity-d_1895.html
  9. Could you explain what you mean? EDIT 15:51 I can't reply to this thread but I can point out that I didn't give you the negative rep point. Would you like to explain what your post was about?
  10. The link doesn't go anywhere useful. I haven't seen the film but I;m guessing there' some chemical in it which destroys iron. That's impossible. The film is only a story; not real life.
  11. American agencies may well break the law to get hold of data. Chinese ones don't need to because the law gives them the right to. Do you understand the difference? Wrong tense, but that doesn't detract from the Chinese govt being worse.
  12. Just as well I asked about a whole class of predictions, isn't it?
  13. Your evidence seems to be the word of a man in China who, I suspect, wasn't born at the time. And your case is something which I already said You may suspect that , but the facts don't tally. You won't often see pork in a Phall., unlike the traditional vindaloo.
  14. OK, but we have to ask what do the "other side's" models say? The big energy companies have plenty of money to spend on looking at this, and they have an obvious interest in doing so. What do their predictions look like? Well... https://www.theguardian.com/business/2023/jan/12/exxon-climate-change-global-warming-research
  15. TBH, when I first saw this topic I didn't pay much attention. I don't use it and I'm not in the USA so a ban wouldn't make any difference to me. I assume I'm not the only one But the subject also got flagged by the IT security people at work so I was paid to look at it They posted a link to this https://www.theregister.com/2023/03/27/china_crisis_is_a_tiktoking/ and the problem isn't really Tiktok it's scarier than that. The article is worth a read.
  16. That's why we have proper mustard and we at least popularised and possibly invented invented the chicken tikka masala. It's pretty clear that we invented this https://en.wikipedia.org/wiki/Phall
  17. Apparently not any more. "Florida (split from The Official JOKES SECTION :))"
  18. So, you don't like being told that you are wrong. Can you expand on that- maybe give a link to what you are on about?
  19. That's one problem, and is hard to deal with. This is the easy problem.
  20. If the USA and Capitalism are so great, they don't need to ban tiktok. They just need to launch a better platform- made in the good old U S of A.
  21. The Scots are from Britain and you could have a long argument about the Irish. The idea of "European Americans" is also a bit daft (choose one or the other) but that's a different question. The country can't really afford either.
  22. Is Boris Johnson English or American? He was born in the USA but moved here and got UK citizenship. Did his appearance suddenly change to match? His situation is not rare.
