  • What is Information?
    I guess we would have to say your imagination is a physical interaction neurally?Pop

    Good observation! Yes, the forms whirling around (forms are indeed the thing) in my inner world couldnt exist without interaction. Like the forms in the ohysical world. In my neural network virtual ALL forms cen whirl around. Interactions shape bith forms (in bothe the outside and insude world(. Both forms are interdependent.

    Do you really mean phase space rather than reciprocal space? Then you're doing it wrong. Or, more likely, lying about doing it at all.Kenosha Kid

    Why are you not the one lying?For a physicist, as yiu claim to be, you make a lot of fundamental mistakes...

    I mean phasespace. The combined view. Luckily I had a good teacher. The Wigner function rules suppreme there. Position wavers and momentum converges.When the system doesnt interact.

    Rubbish!
  • What is Information?
    Only the position operator can be used to find expectation values of the wavefunction." Which is, of course, total rubbish.Kenosha Kid

    Where did I state that? The momentum operator can too. I do QM in phasespace.
  • What is Information?
    That observation is an interaction.Pop

    I dont make an observation of the state. I imagine it. It can exist without me interacting with it. The state came to be because of interaction, thats true. In fact interactions are necessary for systems to develop. Isolation does no good for a system. It gets more and more diffuse. If all the systems mass is converted to photons (by introducing antimatter) the photons posses energy but still the information is zero. Of course their the associated quantum field configuration contains energy. But that's pure energy. Pure energy (photons but also gluons, hypergluons, or gravitons) does not necessarily contain information. The same holds for mass. Its the *form* that contains information. Be it entropic (the number of states) or the different forms containing the same entropic information (the different figures on a oiece of paper). These different forms owe their existence indeed to interactions. A number 8 form is different from the other numbers because of different interactions ( but they contain the same number of information). An 8 written up by us has the information content of being a number. So have the other digits written uo. They need interaction with brain content to get their useful meaning. For a person loving ballgames, the 8 resembles two piled up balls. The 6 can be a head with a hair on one side. Evolution of lifeforms took place because the Earth finds itself rotating between the hot sun on one side and the freezing space on the other. Heat flowed on the surface of the Earth giving rise to different forms in matter like the diiferent digits on the paper. Every living system contains about the same number of information but not maximal nor minimal. Different animals are as it were the different digits on paper. But with eyes and nice different bodies and different internal and external worlds.

    Also when you interact.
  • What is Information?
    You cannot provide me something that has no information - ever!Pop

    A state of matter at zero Kelvin contains zero information. There is only one state. Since S=lnN the information is zero.

  • What is Information?
    Information is interaction.Pop

    Why is that? Ten equal pieces of paper with different numbers on them (1 digit) contain the same information (when expressed as a number). The form of the different numbers is different though. The entropic definition of information does not take that into account though. Does interaction?

  • Did Socrates really “know nothing”?
    . In this subject, however, I claim to be skilled above anybody who has ever lived or is now living in the world

    What he means by that...? :smile:

    I think the best way of his knowing that he doesnt know anything (which he obviously knows) is that he doesnt know the Nature of reality. From which to choose his one? The gods, Plato's ideal world? The reality of married life? The reality of being a man in power or that of an obedient slave? He doesnt know. And that he knows. Hes honest in not pretending to know though, but if he knows he speaks.
  • What is Information?


    "The wavefunction is the total information about a system,"

    Almost correct. The wavefunction contains only information about the chances where to find a particle. Or the chances of finding a momentum in a certain range. The total information about a system is dependent on the configuration of the particles wrt to each other. But if there is no interaction with the systems surroundings, this wavefunction wavers out in phasespace (well, the position part wavers out while the momentum part collapses). After a while all useful information will be lost. The chances are conserved though (unitarity). Information about these chances, or better, the particles with their chances are conserved whenn falling into a black hole.

  • What is Information?
    Shannon information is the particular things we'd need to know about something to e.g. build a copy or predict its future behaviour. Shannon entropy is essentially the number of things we'd need to know (or rather a function of that number).Kenosha Kid

    No and yes. You use 2 different definitions of Shannon entropy here.
  • What is Information?
    Information is still afaik the content of those messagesKenosha Kid

    Again no. The information contained is not the content. Its just a number.
  • What is Information?
    Entropy is a function of the number of possible messages.Kenosha Kid

    No. Entropy is a function of the possible permutations (S=ln(N)). Not every permutation contains a message.

  • To What Extent is the Mind/Body Problem a Question of Metaphysics?
    Also, while disembodied consciousness is problematic it is also moving into other dimensions, or the realm of imagination.

    What other dimensions do you mean? You presuppose that disembodied consciousnees is possible in the first place. Its impossible in principle.

    It is hard to know where mind and matter end or merge here, and which impacts most. The brain can damage experience but we could also ask whether the 'mind' can damage physical organs, on a psychosomatic level.Jack Cummins

    Mind and matter merge in the body. The mind can alter the body and certainly influence it. By the very Nature of the mind its very unlikely that the brain can do damage to the body as the body can do to the brain. Though you can always automutulate.

    What's the difference?
    Less will die or more will die. Freedom is at risk in the first case and assured in the second case.

    As an irrational anti-vaxxer (why should I be thankful?) the second case seems to be the more appealing as long Im alive. I dont agree with that Philippinean tyrant who wants people to be put in jail and have a needle stuck in their ar....., eeeehm, bottom. "Bottoms up, preeeesent aass!" No thanks.

    Last month loads of that stuff were superfluous here in Holland. Why not giving them to poor countries? Costs too much. Maybe THAT's something to worry about!
  • What is Information?
    Would you equalize them necessarily?Pop

    Yes. Every book contains the same AMOUNT of information. Considering equal books with an equal amount of symbols. The Shannon entropy as well as the thermodynamic entropy are equal. But the books are very different, if they are a book on non-perturbative quantum gravity and a book on the philosophy of science by Paul Feyerabend.

  • Why do people accuse others of being a troll when the going gets tough?
    "I'm beginning to think, like others have opined, that you might be a troll. At first I understood the inability to use the forum tech. After all, I'm no tech guy myself. Then I thought it was your fat fingers on your cell, as you suggested. But there's something more than typos here. Finally, I thought that maybe English wasn't your first language and that maybe you sounded like a fool for that reason. After all, you're a physics guy so you can't be stupid. It must be the language thing. But when you are patently obstinate, I'm inclined to put you on my informal, personal block list. Hmmm. I guess I'll hide and watch."

    I will look for the other accusation.

    Then we have:

    "
    Please stop spamming inane shit"

    To happily end with an accusation of somebody telling me I dont understand metaphores and me certainly being a troll.

    Now I have seen the real trolls and they are impressive 100ft tall creatures. I think its too much honour for me as a 6ft small guy.
