  1. SMBH?
  2. I see two feet that rest on the bottom of the pan providing friction and hence the torque. What I don't see is "a problem to address" .
  3. What's the field of research? If, for example, you are looking at oestrogen receptors, you are allowed to publish results that say males are different from females. What you can't usually expect to do is publish papers that say "we didn't bother with these results because they were measured by a female member of staff and- you know- they just suck at science." There are published studies on things like correlation of exam scores in monozygotic and polyzygotic twins which strongly indicate that some of the ability to do well in exams is heritable. That may not be politically popular in some circles, but it's observably true and thus scientifically publishable. It's hard to see how anything in chemistry could be controversial. It would be good if you clarified what you are actually talking about.
  4. It's not even a joke, it's just nonsense. There was smallpox in the past so medicine thinks that time is smallpox.
  5. The components from which the is resin made are relatively toxic, but, during the curing process, they react with eachother and the product is pretty much harmless.
  6. Yes.
  7. Reminds me of this joke. An astronomer, a physicist and a mathematician are on a train in Scotland. The astronomer looks out of the window, sees a black sheep standing in a field, and remarks, "How odd. All the sheep in Scotland are black!" "No, no, no!" says the physicist. "Only some Scottish sheep are black." The mathematician rolls his eyes at his companions' muddled thinking and says, "In Scotland, there is at least one sheep, at least one side of which appears to be black from here some of the time."
  8. I could use a laugh; lets see you find some bit of modern physics that says what you claim it does. Or, perhaps you could just agree that you were utterly wrong.
  9. Why do you "need" details of an orbit that can't exist?
  10. Refrigerators designed to maintain -80C are commercially available for use in laboratories + such. They are not cheap. If there was a cheap way to do it, then people would do it cheaply + undercut the manufacturers.
  11. If you have looked at the first few, and got the wrong answer, it's time to stop. And that's the wrong answer.
  12. Whoever they are They are wrong and you should have cited them. Incidentally, the links in the Linkedin page you gave as your source all point to WIKI. To me that suggests that WIKI is the original, and your source is a copy.
  13. Your "general rules" are wrong. I cited specific examples that prove it. And, since an alloy is a combination of metals, ITO isn't one. Wiki has got it wrong (and, BTW, you should have stated that you were copying what you wrote from WIKI.) https://en.wikipedia.org/wiki/Indium_tin_oxide
  14. Incidentally, am I the only one who first misread the title as "beer gut"
  15. It's a matter of definition. Is Concorde a modified bicycle?
  16. Wrong on practically every count. Manganese is one of the worst conducting metals, yet it has lots of valence electrons. Silver, on the other hand is usually regarded as having just one, yet t's the best conductor. The indium tin oxide referred to earlier is an oxide (not a metal) but it's quite a good conductor. Not all metal oxides are ceramics. From most conventional definitions, glass isn't a ceramic. Some ceramics make good magnets, but not all of them. Similarly, some metals make good magnets, but not all of them. Why did you post that stuff when you clearly know so little about it?
  17. It's a very useful material used, among other things for the pistons in high pressure pumps. But it's still not a metal
  18. It's strictly quantised in units of h/2pi
  19. "How will humans survive serious infections in the future if we're running out of tools today to fight them? " The same way we used to; lots of us will die.
  20. Without messing about like that, angular momentum is a vector. No. It's a conserved quantity so it doesn't usually vary.
  21. Look at a ruby; its aluminium oxide. (and, like ITO, it's not a metal)
  22. You can see through gold leaf, but it isn't very robust.
  23. Meanwhile, back in reality... https://en.wikipedia.org/wiki/Catholic_Church_sexual_abuse_cases https://en.wikipedia.org/wiki/Anglican_Communion_sexual_abuse_cases and so on.
  24. No, it's not.
  25. Be careful what you wish for. It's easy to get my attention- just post trash.. If you want the mods' attention, just declare that you are trolling.
