  1. As far as I can tell, it's from some person on Quora https://www.quora.com/What-are-some-examples-of-natural-substances described as "Mohammad Hasnain, studied at Colleges and Universities" I don't see that as particularly authoritative. To be blunt, if one of the resident experts here says something categorical like "It isn't natural", you should probably check damned hard before trying to rebut it.
  2. It isn't natural. It isn't organic.
  3. That's not a good start, but... whatever. If you ant to look like a smurf, that's your problem. You have been warned. The kit you have is nice enough, you might also need stuff like a soldering iron. And a word of warning HP made good kit, but it's rumoured that they dropped the HP name because everyone said it stood for "Higher Prices". Probably less of an issue buying second hand. We live in a weird world. It's possible that getting a newer computer will let you use new er equipment which is paradoxically cheaper- think abouyt teh stuff made for arduino etc.
  4. Am I the only one who thought of this?
  5. And yet there are solutions, every bit as valid, that do have black dots. I may be wrong, but I doubt it's from a real IQ test. They are usually careful to ensure that there aren't too many "right" answers.
  6. Did you see all the other reasoning that disagrees with you?
  7. I would put a lot more effort than I should into making the mat slightly bigger each time...
  8. The HEPA filters used in biohazard labs would fix it. The problem is largely the noise from the fans. Bacteria and viruses are particulate. The ones where they don't allow people are probably pretty near sterile for exactly that reason.
  9. What grade 3? Maybe, by way of balance, the media should not turn up to his election gigs.
  10. You can do it, but it's not easy. https://en.wikipedia.org/wiki/Cleanroom The problem is the hurricane you need . A cough can travel as fast as 50 mph and expel almost 3,000 droplets in just one go. Sneezes win though—they can travel up to 100 mph and https://www.lung.org/blog/sneeze-versus-cough
  11. Essentially, the problem is not adequately specified or has no unique solution.
  12. ... but the magnets are rotating, so...
  13. Presumably, his comments on chloroquine, (and mexico paying for the wall etc.) are like his idea that people should try mainlining dettol- just sarcasm.
  14. https://www.agilent.com/cs/library/applications/5991-4191EN.pdf https://pdf.sciencedirectassets.com/278653/1-s2.0-S1877705813X00037/1-s2.0-S1877705813002452/main.pdf?X-Amz-Security-Token=IQoJb3JpZ2luX2VjENz%2F%2F%2F%2F%2F%2F%2F%2F%2F%2FwEaCXVzLWVhc3QtMSJGMEQCIEIlWT3IeFVnV6sgQqQ37xtiRmgN72R5JT20FzEHTpM9AiBInn9bsaSkYiO%2FEz7w7Jpstn6DtMBExrf0cEzT9qSicCq9Awj0%2F%2F%2F%2F%2F%2F%2F%2F%2F%2F8BEAMaDDA1OTAwMzU0Njg2NSIM09o9DOnzDe6aG4OcKpEDTOHASYQU8vdy%2BqfHkk5T4%2BN9uY8vf70Li9%2B0CP6uyMHDKwkj4XDjiO4VIY%2FwS6YqWXl%2BQh2ZcH4ofMzuZcI2C5GCswVz9W1fxup8REnxRvNdTtwwapNzFpiwn55eRqFH0nNHB3O0YZqj3Y%2FvTM0wHqY2FOJBYogKOGwcDbL1e%2FbwaQg3XFpt8oRXRpDDepBcAZFTJq5ran%2Bk%2Fei7VGbY3rweIF0OfGfkI%2F7umChLAy21LdxzXXdim75UKLqZnaDlqMTIRaTxaNDW7%2FKcwS6Rw40D1KiGDH8eNBFNzZdzjy9cu8rEEIq4wb5YdMIKaZl0lpQXSn179mvydlyKHpeMPYFZb7b%2Bkg7%2FCtkDGCoHFkB23dH%2BUyDDdomW8ncyLUT8vzDmz4JwAubNoQlCqfFjJISj9DEVbF0K6lU%2FT%2FA2qO8E7xg2iSZjdmGX9byhOEHdVVSOieJpcw3dNtG6GUOg5sw7zXNQVPrx0XgTUey4HzhOt42%2FHDVotXRkwN011YeqKGWL97R8QXfFHxMTG4VNT40wpsny9AU67AH%2FYxVM6WUIEk5Bn2NawP0lczwS%2BZNlCCuC5W0ymi87cPj4hKXr2HcdvwEJvKBMHvg2Q5Wjtu%2BTqj9qzaUWqilYNuSyZ4abtaQpJv485HywV9xLsO3CO11a%2BtBXTh17p51L1krdJKoIw0V24GdxqdBqBDTt8lg0lX5QL9ZzIL1TEPrKMpU%2FAFXoX1k2I1us8hbmOT9ZVbgsEtU5faPHYgdqjWdLZM6Ts%2FIuSTVHE4JHIdK3mmf2G%2Ftd3nPKNvk9fPSmOf%2FAw6qIymX2NSuUKlsoHJhDXkHBPwcsfBrjBOdoSfIdF%2FwyGK6V9G59Rw%3D%3D&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20200419T203542Z&X-Amz-SignedHeaders=host&X-Amz-Expires=300&X-Amz-Credential=ASIAQ3PHCVTYTAE5DEQW%2F20200419%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Signature=06317f241a6551ef78f57849f6e28d5d9daef449af141a2451645456096c24b1&hash=de924d0b0578748b83ed7239617fe009c19be7d9faf8c58eb14a045e5d7870fc&host=68042c943591013ac2b2430a89b270f6af2c76d8dfd086a07176afe7c76c2c61&pii=S1877705813002452&tid=spdf-c096a25e-9af3-4b98-9148-5b2d505a7ec9&sid=a138e96326cc704c853a74b04a89830300cbgxrqb&type=client
  15. Could have been freezing.
  16. Because it is wrong in many ways. All the relevant ones. It is entirely possible to build circuits where most of the conductors are not mental. But that's not the point. You do not NEED a metal. This is not a language problem. As far as I could tell by looking through it quickly, there were no experimental data presented in that document.
  17. Nobody is going to have compiled that list. Apart from anything else, it is impossible, because the materials are slightly variable. We have the genome, and the proteins involved which are the major components, but those are not precisely conserved from one virus to the next. Since you are looking for something impossible, I think your viewpoint is doomed to fail.
  18. That isn't obvious at all. It's quite possibly not even true. Unless it isn't. The term is also used for these http://www.hambletonbard.com/how-to-make-wine-beer-moonshine-alcohol/wine-alcohol-meter-homebrew-vinometer.html Except it won't work very well. A saccharometer will be designed to measure densities above that of water. Solutions of alcohol will be less dense than water. To use a hydrometer to get anything like an accurate measurement of alcohol concentration of wine or beer, you need to know the density before and after fermentation. Otherwise the other components of the mixture will influence the density and thus the apparent alcohol concentration. In the absence of better data, about half the weight of sugar becomes alcohol.
  19. You could sort of make an argument that this https://en.wikipedia.org/wiki/Second-harmonic_generation is used to generate green light from infrared using an "antenna"- the electrons in the frequency doubling crystal. But to make light in the "classic" electrons moving up and down a wire way, is a non-starter.
