  1. Yes, frogfish and other walking fish are quite common in Bonaire. That is why the article title looked wrong and misleading to me. But then I thought, maybe I just read it wrong (as English is not my native language.)
  2. You might know about unusual amounts of Sargassum appearing in Caribbean in recent years. Here, in the Southern Caribbean we also started to get it and it is not good at all. Here is how it looked this morning in a lagoon on the windward side of the island: I don't know details but guess that this phenomenon is a consequence of the climate change, which causes changes in water temperature distribution and currents. Any thoughts?
  3. The title of this thread is a title of recent article (Photographer Nicolas Remy captures image of the rare spotted handfish | CNN). How would you read it: the photographed fish is rare, or a fish walking on its "hands" is rare?
  4. I don't see what makes you think so.
  5. Eating things that taste good is a basic bodily function.
  6. Everything except basic bodily functions.
  7. Not exactly. I'm saying that we do things for various reasons, and pleasure or pain are responses for our success or failure to do what we wanted.
  8. Isn't it the other way around? I.e., whatever we're determined to increase gives us pleasure when it increases, and whatever we're determined to decrease gives us pain if it doesn't decrease.
  9. As it was two days ago: https://www.scienceforums.net/topic/128859-physics-in-troubles-the-real-equation-of-force-is-f-ma-and-not-f-dpdt/?do=findComment&comment=1230793 (there is a link inside this link)
  10. If it is, at least it's short.
  11. You have misunderstood. I am not in a discussion with you. I just contributed couple of comments to the thread, but I did not refer to you in those comments, as you can check. You are free to ignore them. I am not looking forward to your reply.
  12. Well, it is more OT, but I was also tired of meeting people thinking that it's OK for their neighbors to be sick without medical insurance because they have different views on how tax dollars should be spent.
  13. Maybe it's just semantics, and in fact CWII and WWIII aren't very different.
  14. Moreover, the kinetic energy E = mv2/2 = mvv/2 = Pv/2 Since P is not conserved, E is not conserved. Tha law of energy conservation is wrong. The entire Physics must be rewritten now. How exciting.
  15. BTW, the law of momentum conservation is wrong, too. You see, as the mass of the chunk of ice goes down, its momentum goes down as well. So, the momentum is not conserved.
  16. Imagine a chuck of ice of mass m flying peacefully in space with the speed v. There are no forces, F = 0. The ice slowly melts. The momentum of the ice P = mv. Thus, dP/dt = mdv/dt + vdm/dt. So, either the chunk of ice is accelerating, or F = dP/dt is wrong. Or, I don't know what I'm talking about. Or, just maybe, I am a troll.
  17. G/h = 10number of Crocodilian species
  18. (Speed of light) * (1 ns) = (1 ft) (Avogadro number) = (number of stars in the observable universe) g = (Human population in 2050)
  19. And, as I and, evidently, you know, it was Russians who defeated Germany, while allies jumped in when it got clear to them that Russian are winning.
  20. Yes, it's as much significance as you can have without committing major acts of sedition or heroism. But it only works once. After you've become part of a new community or nation, you are expected to contribute to its welfare, help shape its future. You no longer matter to the old one, but you still can matter. Only once? I think it works every day. I keep taking my money from a country A and spend it in the country B (B for Bonaire) for many years. Every time I do it, I transfer my economic activity, don't I? (Of course, I do other things also in the country where I live, for example, volunteer for the Animal Shelter, recycle, etc.)
  21. idk. I've never heard of such a parallel. AFAIK, conservation of quantum information is a consequence of unitarity of quantum system evolution. But this unitarity gets broken by an act of measurement.
  22. I don't think it is strictly so. There is always a (theoretical) observer for whom a specific piece of quantum information is still there, but for any given observer the quantum information disappears as soon as they interact with it. This is my understanding of it.
  23. Some hostile act added to the picture almost daily. Today (yesterday?) they suspended new nuclear talks...
