  1. So... the guy who thinks profs are arses is not treated with respect by profs. The other people are treated with respect. I wonder if those observations are related.
  2. I'm curious. Why didn't you consider it with an open mind? If you had, you would have realised that we keep on sending rockets, but the hole is shrinking. So, it's obvious that the idea is wrong. Why didn't you notice that?
  3. Do you even realise what that means? It would mean that those affected didn't snatch their hand away when they put it on something hot. They also wouldn't have the classic "rest of reflexes" response to being tapped just below the knee. Do you somehow imagine that people wouldn't have noticed these traits?
  4. People measure the actual forces in bones by connecting strain gauges to them. http://www.ismni.org/jmni/pdf/43/02YANG.pdf If the results weren't what was expected from normal physics, people would have noticed.
  5. Not really. Second cousins, especially double ones, are quite close. So, not only is there a correct English term for this, your suggestion is factually wrong.
  6. That's what they thought in the 19th century. In the 20th , they realised that the smoke doesn't "blow away", because there is no "away".
  7. I'm pretty sure that the OP has posted this idea on other fora and failed to listen to the replies he got. I can't see why it's going to work better here. (and the same goes for his other ideas based on magic.)
  8. That may be the only "useful" thing that anyone learns from this thread.
  9. You were beaten to it. https://en.wikipedia.org/wiki/Secchi_disk#Secchi_depth but it's a good, simple, cheap way to compare turbidity
  10. Do you understand that pages like this one are a joke? http://hmpg.net/
  11. You can buy deuterium depleted water. Which means you start off with 0.0115% deuterium and get 0.00815 % (or 0.01311% if you are trying to concentrate it.) You need a lot of stages to get a good product.
  12. Because the hole is repairing itself since we stopped using so much CFC. The VLF is not going to make much difference to it.
  13. Just one credit will do; He put the serpent in the garden of Eden and He is therefore solely responsible for everything bad in the world. Think about that...
  14. Two points. I suggest that you look at them first. and re. "nobody needs data from 30 years ago", ask an historian.
  15. Good. And at a hundred times the intensity... the plastic melts- which doesn't happen with sunlight, no matter how long you leave it. Accelerated aging tests (often relying on Arrhenius plots) are great, but not infallible. https://en.wikipedia.org/wiki/Arrhenius_plot
  16. How do they know? 😉
  17. I just wish I didn't come across so many people who seem to be engaged on research in this field.
  18. Should the people who are most likely to come up with new ideas and discoveries be employed as scientists?
  19. Nice bait and switch there. The thing about "falling" is that it implies that the direction is "down" so there is information about a trajectory.
  20. Slightly less useful; you couldn't even fertilise the rose-beds with it.
  21. That's interesting. You could say the same of platinum and silver. But their relative cash values change.
  22. Not that I'm aware of and, if you are writing about something obscure, and fail to explain what it is, then you are writing badly.
  23. The spherical harmonics are not, themselves, spherically symmetrical. But the sum of the trio of P orbitals (one on each axis) is symmetrical.
  24. It's more than that. The atom can not know what axes you chose for your coordinate system and must therefore have an shape that is independent of your choice. The only way it can do that is to be spherical.
