  1. I think that "doctors" in advertisements seldom are real doctors, that in most cases they are just actors/models.
  2. That man is a crackpot. He doesn't seem to understand the difference between rest mass and relativistic mass. Relativistic mass is a somewhat outmoded concept. It is related to the total energy E of a particle, (mrel = E / c2 )and therefore dependent on the velocity with regard to the observer. If the particle approaches the speed of light the energy and therefore also the relativistic mass increase without bound. Today we prefer to use the rest mass (the energy of the particle at rest, divided by c2), which does not increase with its velocity. It is just a different definition, the calculated effects remain exactly the same. He also seems to think that the neutrino doesn't exist, claims that it has no mass and no spin. Well neutrino's do exist, do have mass (even if it's very small) and certainly do have spin, and they can also be detected. So listening further to this man is wasting your time if you want to learn something meaningful, because he really has no clue.
  3. I can read the article without subscribing (following the link given above), no problem.
  4. I haven't posted for some time here, because most discussions are now about American politics and conspiracy theories, neither of which interest me. In most cases I don't know the people concerned, or have only a vague notion who they are. I prefer to discuss things I know something about.
  5. I suppose it is this Doris Gordon:
  6. I just give some possible alternatives to Ellen's notion that "not being able to handle criticism" would automatically imply "banning your opponent", that's all. I myself don't continue a discussion if I've clearly stated my viewpoint and the other side is just going to resort to personal attacks. In such cases I let the other have the last word, I'm not interested in some endless ping pong game that doesn't solve anything.
  7. "Not being able to handle criticism" doesn't necessary imply banning the other person. It could also mean "always insisting on having the last word", or "not being able to say 'lets agree to disagree'" for example.
  8. The ten climate commandments: Among the worshiping public, Pope Franciscus, German Chancellor Merkel and President Steinmeier (the owl). April 2019. Of course, today many other politicians could be added...
  9. 23 minutes ago, Jon Letendre said: Sorry, I took you for meaning the dumb ones’ failures are ignored, but you surely meant the fails, period, are ignored. Do have experience with cats? Allowed outdoors? You’ve watched them while they are outdoors? In my experience the intelligence depicted in the video just scratches the surface of cats’ abilities. Almost my whole life I've lived with cats. Only when the last one died, 18 years old, we've decided not to take another cat, as that one would probably survive us, and that is an unbearable idea to us, as we've no idea what would become of it then. And yes, they can be clever. When it suits them.
  10. It wouldn't affect that proposition, but neither would it prove it. The file drawer effect or publication bias is a serious problem in many research fields, like psychology or medicine, not ot mention more dubious fields (it's the way to "prove" with spurious significance values desired theories.) If the skill is genuine, I think the cat uses a different strategy. In the video you can see that the cat sometimes doesn't look at all at the cups, so it wouldn't have been able to keep track of the right one. I think a more likely explanation is that it reacts to the sound of the ball. No need to keep track of the relevant cup, it just hears under which cup the ball is still rolling a bit at the end, That said, I think that a perfect score as in the video is unlikely, so there probably has been some cherry picking for the end result.
  11. Very funny and charming, but of course cheating is very easy. Just don't publish the articles that don't confirm your thesis, um... I mean. don't show the videos that don't contain the desired result. That's called the file drawer effect.
  12. I think it's highly unlikely that any sophisticated form of life that is not carbon based can evolve anywhere in the universe. It's the carbon chemistry that is at the basis of the enormously complex and sophisticated machinery that makes such life possible.
