    A survey taken among physicists about the concept of "real" in physics is linked and I think most interesting. First, I am posting a similar poll for comparison.

    The survey is at the bottom of the linked page:
    http://physicsweb.org/article/world/15/4/2/1#2

    Note: I will post this in the philosophy section for comparison also.
    Please vote in the forum most appropriate to your perspective; but not both.

    I agree. Thanks Wimms

  3. All of them are real...and many others...
     
  4. I left out color and hallucination. I'm not a physicist anyway.
     
  5. It would be interesting if here voted only people who are directly engaged in some kind of science. Then comparison between scientists and laymen in this site would be revealed.

    I voted in phil forum and suggest nonscientists to do same.

    My humble opinion.

    Colors and hallucinations depends on people's perception. They are real or not depending on a man/woman perception.

    The rest, since it can be measured, the measure is the same in the same conditions, and do not depends on the man's perception, are real.
