  1. If you find the same relation in multiple cases, then there is a correlation. Now, obviously, correlation is not causation. But we can eliminate the future birth ratios as a cause of starvation. And, by looking at other factors, presumably it is possible to eliminate those as a common cause. So you would be left with the correlation as the most likely cause. (This isn't very unusual; it is how the health effects of smoking or diet are investigated.) More here: https://www.smithsonianmag.com/smart-news/times-of-famine-linked-to-disproportionate-number-of-female-births-1110208/ (Luckily, it seems to support my guesswork! )
  2. Tidal force also falls off with inverse cube of distance; this seems to be a sort of mirror image of the magnet case.
  3. If it is true, then presumably it would be based on birth statistics in periods of starvation or malnutrition.
  4. You can't have it both ways. Either there are quantum effects, in which case Planck was right. Or there aren't, and there is no Heisenberg uncertainty principle. It will still reach equilibrium. Quantum fluctuations are the minimum energy level, not a source of energy.
  5. I am not going to create a facebook account just to read something that you should be presenting here. There is no such thing.
  6. What is "this"? Facebook? You are not making much sense, you know. (You should try looking at the page you linked to when you are not logged in to facebook: there is nothing there.)

  8. Maybe you need to seek professional help before this becomes a problem.
  9. What exactly is this mysterious aspect of reality? How about putting it forward here (this is a discussion forum, after all). Apart from the fact it is a violation of the rules, your facebook page is not accessible. That is mysterious.
  10. Because it is a dipole (north and south poles). So they tend to cancel each other out more as you get further away (and they get relatively closer together).
  11. This seems self-reinforcing. In popular entertainment, the first thing the hero does is reach for a gun (because it is easy to get one) so people expect it to easy to do and so, in fiction it is plausible for the hero to have a gun and so ... I guess a lot of this goes back to the “frontier spirit” that is idealised by westerns and hunting stories, and embedded deep in American culture.
  12. I would say that special relativity is more about the relationship between time and space, as seen by different observers in relative motion. The equivalence of mass and energy can be derived as a consequence of relativity (and Maxwell's equations). General relativity adds to this the effects of mass and energy causing gravity. Not just constant but, more importantly, invariant: i.e. the same for all observers.
  13. Damn! I meant to add that parenthetically. You couldn't make this stuff up: "NRA Board Member Blames 'Sympathy Factor of Kids Getting Killed' for Possibility of Gun Control Laws Passing" These guys are not human. http://www.thenewcivilrightsmovement.com/davidbadash/nra_board_member_blames_sympathy_factor_of_kids_getting_killed_on_possibility_of_gun_control_laws_passing
  14. And it is worth remembering that there is no good evidence that people with mental illness are any more likely to commit crime.
  15. Correlation in not causation.. The majority may heave been on medication because they were the types more likely to do this sort of thing.
  16. The Alpha project at CERN regularly makes "large" amounts of antimatter (more than anyone else, anyway). Their latest results are based on measurements of less than 200 atoms.
  17. I suppose it might be useful for us outsiders to understand a bit more about the relationship between the various national armed forces, it looks very complicated! These look like a good intro: https://en.wikipedia.org/wiki/Militia_(United_States) https://en.wikipedia.org/wiki/United_States_Armed_Forces So, even in that context, it is a (local) government militia. I assume (hope) that the extreme anti-government types are in a distinct minority in the US.
  18. It sounds from both the second amendment and the section quoted by Ten oz as if the country did not have a significant standing army and so needed an armed populace to call on in case of war. (This was a very common model historically; the idea of established armies is, I believe, quite a modern idea.) I gather a lot of NRA supporters claim that the population need to be armed to protect them from a repressive government(*). But the section quoted specifically says "to suppress insurrection" so if the "militia" tried to rise up against the government, this would just lead to civil war (as in any other country). So their argument appears to be completely unsupported by either the 2nd Amendment or Section 8. (*) I thought that was what democracy was for

  20. Apparently Trump is now threatening to put a tarragon imports of cars from the EU: http://www.bbc.com/news/world-us-canada-43270388

  23. Apart from the fact that the hierarchy is fairly bogus (like much pre-scientific psychology) it doesn’t include “self-transcendence”
  24. The "old-fashioned" (Newtonian) definition of acceleration is just a change in speed caused by a force. And Newtonian gravity is a force. In GR, acceleration and gravity are the same thing. So if you are in a sealed box with no view of the outside. you cannot tell if you are sitting on the ground or accelerating through space at 1g. If you feel a force pushing you then you are accelerating. So someone in free-fall, e.g. in the space station, feels no force pulling them on them therefore they are not accelerating. If you can feel your chair pushing up on you then, in GR terms, you are accelerating. Sounds like a very inefficient way to learn. But whatever
