  1. The Earth is not actually expanding, nor could it ever have done so in the way you are talking about.. Stop ignoring reality.
  2. If you are using a translation table to alter the force on something, it may be easier to use a spring instead of the electromagnet. What are you actually trying to do? Controlling the current is the obvious way to control the force, and I wonder why the OP hasn't chosen it. For a few hundred kilos of force you really don't need superconductors. https://en.wikipedia.org/wiki/Electromagnetic_lock#Electrical_requirements
  3. I'm fairly sure that I can use an arbitrarily weak magnetic field and still make as powerful a motor as I wish by using lots of turns of thick wire. It would be stupid, but I can do it. And that proves that there's no single answer to the question. If I wanted to get a sensible design for a 10KW permanent magnet motor... I'd look on the web and copy someone else's design. I can buy one with a shipping weight of 31 KG (the first one I found on Google) so the answer must be "Less than 31 Kg".
  4. Thanks. That's clear enough. We know the Earth's not expanding so we know we can discount one of the theories. I suggest you hold a vigil for the lost soul of your idea and then lay it peacefully to rest. It's not coming back.
  5. The likelihood of fusion varies with energy (and the nuclei being fused) https://en.wikipedia.org/wiki/Fusion_power#/media/File:Fusion_rxnrate.svg
  6. Oddly, it's the other way round. There's so much water in vinegar that, when you cool it, the ice crystallizes out first. Eventually, you get to a mixture where both freeze out at the same time There's some discussion of it here https://chemistry.stackexchange.com/questions/2506/acetic-acid-freezing-distilation
  7. Freezing out the water is also an option- especially in Winter. Of course, that's not when you need weedkiller, so you need to plan ahead.
  8. It struck me since my last post that there's a bigger issue here. How in the name of all that's holy is "breaking free of the Pacific Plate" from "the Asian mainland " anything but plate tectonics? There's possibly an argument about where the boundaries are, but plates moving away from each other + carrying landmasses with them is exactly the "myth" that the OP objects to. And that's before we remind him of his "rather fragile" idea about the Earth getting bigger. Essentially, his equestion"Plate Tectonics: A Modern Myth?" is best answered by reference to his own use of shifting plates on the Earth's surface. If it's a myth Doug, - it's one you believe in
  9. All rotation is relative. So what? What caused it here?
  10. OK, so let's start with the important bit; the guy didn't do his homework. And then there's the fact that those squirrels you mention have been eating grain for even longer. So, how toxic can this stuff be? And, there's the fact that data isn't the plural of anecdote. And, if you think the only thing in pretzels is gluten then you haven't thought it through. So, you may well be imagining the effects. or it may be one of the real effects- it's not as if anyone disputed the fact that it causes problems for some people.
  11. The evidence says about 10,000 for deliberate cultivation, and heaven knows how long before that.
  12. A couple of things happen. Firstly the molecule is usually torn apart by the recoil. Secondly, the decay produces an alpha particle. It bounces round until it loses enough energy to pick up a pair of electrons and become neutral. Those electrons are taken from something else, effectively oxidising it. In the middle of a piece of Ra3N2 the nitride ions would be oxidised to nitrogen atoms which would combine to make nitrogen gas. However, the molecules are not always ripped up by the reaction. This sort of thing was the first ever synthesis of the perbromate ion from a radioisotope of selenium. https://en.wikipedia.org/wiki/Perbromate (for what it's worth, I also don't see what Studiot is on about)
  13. Yes. It's a natural part of wheat (and some other grains) And, the body is quite capable of making glutamine if there's none in the diet. Eating gluten isn't the primary issue here.
  14. Once the AI lawyers start to win cases it will get interesting. It might not be long.
  15. Reaction of sulphur dioxide with water does not make sulphuric acid, it makes sulphurous acid which is less corrosive. But there would certainly be corrosion problems from that and other gases- such as HCl. On the other hand, with care you could collect these materials for use- sulphuric acid can be made by oxidation of sulphurous acid and it is a sellable product. It would also reduce the local effects of air pollution by the volcano. However, I'm not sure it's practical. I'd not really want to invest my money in a building on the side of a volcano.
  16. Lateral is all very well. You were asked to explain the rotation. Please do so.
  17. To be fair, if all you want to do is sit round watching daytime TV, that's fine too. The point is that it lets you choose what you do.
  18. It isn't. (Well, it seldom is) However, wheat is used in a lot of food production, and it contains gluten. So it's hard to guarantee that foods are gluten free. It's also important to recognise that humans have been eating gluten (in wheat) for thousands of years. Only a small number of people are troubled by it. For the rest of us, it's food. Gluten contain glutamine. Yes, it does. So does most food. " The polyglutamine (polyQ) diseases are a group of neurodegenerative disorders caused by expanded cytosine-adenine-guanine (CAG) repeats encoding a long polyQ tract in the respective proteins." Yes, they are- they are a genetic glitch. And the two things are not related to eachother. Why did you post that?
  19. Yep. So I expect Trump to do it again.
  20. Watch this space...
  21. Not quite. We have shown that Trump backs down when confronted. No great shock; it's the standard tactic for dealing with bullies.
  22. I'm looking forward to the newspaper headline that says "Trump climbs down over wall".
  23. Like the country, IDS is allowed to change his mind in light of the evidence.
  24. Do you understand that one side lied, broke the law, got prosecuted + fined + reported to the police for criminal action, and the other side didn't? Are you somehow pretending that the situation was symmetrical? Well, it's hard to say. But racism is wrong, and played in favour of "Leave" Xenophobia is wrong, and played in favour of "Leave" External interference is wrong, and played in favour of "Leave" And the margin by which thecheats won is small. Imagine this was a football game and, after the match, it emerged that the winning side had played a "ringer". The acceptable outcomes would be that (1) The cheats would lose by default or (2) there would be a rematch. Why does anyone think it is reasonable to hold the future of the UK to lower standards of propriety than they would for a game of football ?
  25. I'm still waiting for anything that shows that GDPR actually caused a problem.
