    Quantum Darwinism
    ''Quantum Darwinism is a new theory recently
    developed by physicist Wojciech Zurek . . .''
    '' The new theory of Quantum Darwinism may provide such
    explanatory power at a deeper, pre-biological phase of our
    emergent reality. It may provide a key explanation of how the
    classical macroscopic world containing all objects with which
    we are familiar may have arisen from the weird
    quantum world of particle physics underlying it.''

    The most widely accepted interpretation of quantum phenomena
    was first articulated by Bohr. It is most succinctly understood
    as the implications of a number of axioms:

    1)*For every physical system there is a corresponding
    mathematical object called a state vector that has
    no objective physical existence.
    This state vector is the most complete source of
    information that exists concerning the physical system.

    2)*The outcome of any measurement on a physical system
    can be predicted by performing a specific mathematical
    operation on its state vector.

    3)*The outcome of any measurement process on
    a physical system can only be predicted as a probability
    for obtaining that result.

    4)*Once a measurement is made the state vector assumes
    a state such that the same measurement immediately
    reapplied to this state has 100% probability of achieving
    the previous measured result.

    5) The state vector evolves in time according to a continuous,
    deterministic formula except when a measurement occurs and
    then it jumps to the state described in 4) above.

    These axioms are all about mathematical manipulation of
    mathematical objects and are not a vision of physical reality;
    in fact the first axiom explicitly states that the mathematical
    objects of the theory have no physical embodiment.

    Until now no one has found an explanation of quantum phenomena
    consistent with the every day world we experience.
    Quantum Darwinism is such a theory and attempts to explain
    the mechanisms responsible for transforming quantum reality
    from its weird abstract mathematical realm into the common sense
    classical reality experienced in our every day lives.

    Pure mathematics and physics are becoming ever more closely
    connected, though their methods remain different.
    One may describe the situation by saying that the mathematician
    plays a game in which he himself invents the rules while the while
    the physicist plays a game in which the rules are provided by Nature,
    but as time goes on it becomes increasingly evident that the rules
    which the mathematician finds interesting are the same as those
    which Nature has chosen. …
    Possibly, the two subjects will ultimately unify, every branch
    of pure mathematics then having its physical application,
    its importance in physics being proportional to its interest in mathematics.

      Allowed Quantum states are vastly more numerous
      then those we experience in classical physics and are
      the cause of much of quantum theory’s weirdness.
      . . . Schrödinger’s Cat’ . . .
      'Schrödinger's Cat' paradox can only arise if the cat-box system
      is an isolated quantum system.
      That is to say not interacting with its environment in any way.

      Misconceptions around the idea of isolation may be
      at the basis of the 'measurement problem'.

      . . . 'alive' or 'dead'.
      This process is now understood to be analogous with axiom
      4 above but rather than a wave function 'collapse' we should
      view decoherence as the preferential extinction of quantum
      superpositions and the survival of classical states due
      to interactions that may be human measurements buy
      are typically environmental interactions.

      My opinion
      Schrödinger’s Quantum-Cat is NOT an isolated quantum system.

        Basically any measurement can only result in some special values
        associated with 'pointer states'. Pointer states are thus associated
        with the type of measurement being performed.

        My opinion
        When a wave function 'collapse' we should view that as appearance
        of the ''pure point-state'' of quantum particle (quantum's duality problem)

          The resulting theory of Quantum Darwinism is relatively straightforward:
          1) . . .
          2) . . .
          3) . . ..
          4) . . .
          While this process may explain the emergence of classical physics
          from quantum physics it may not be clear where the Darwinian part comes in.
          Zurek explains his motivation in naming Quantum Darwinism:

          Using Darwinian analogy, one might say that pointer states are most ‘fit’.

          Still we might quibble and demand a more formal comparison of
          Quantum Darwinism to the defining mechanisms of a Darwinian process.

          In what sense can Zurek’s theory be seen to be a Darwinian process?

          1)* * * Reproduction.
          Information concerning the state of a quantum system is copied with variations.
          The variations most directly concerning the information’s survival concerns
          the degree to which it is entangled or in superposition with its environment (i.e. non-classical).

          2) Information concerning superposition of point states does not survive decoherence
          as a result of interactions with the environment and only information concerning
          non-entangled, classical pointer states survive as imprints on the environment.

          ====
          My opinion.
          a) Using Darwinian analogy, I say that point-state of quantum particle
          is most ‘fit’ to explain philosophy of Quantum theory.

          “We are not talking about waves or particles, what we are talking about
          is a quantum of action in a field. This thing we call a particle is a quantum of action
          that becomes more focused by a process we have not described and this thing
          we call a wave is the potential in the field.
          How can a wave be quantized?
          The wave is a precise ratio of potential.”
          / ― Rick Delmonico, The Philosophy of Fractals /

          b) How can a wave be ''quantized''* to ''a point-state'', to be particle?
          How quantum ''point-particle'' can create wave ?
          Is quantum particle a ''point, string, ball . . .'' ?

          c) '' Information concerning superposition of point states . . .''
          / Zurek /
          Information as energy cannot be destroyed . . .
          then according to Zurek’s Quantum Darwinism theory
          information can be in two states:
          a) ordinary (wave-state) and b) super-ordinary (point-state)
          ===========

            Quantum Darwinism:
            1) reproduction of information not material.
            2) no competition for supply of resources
            3) no sexual reproduction

            . . . first point is somewhat confusing as it is now well accepted
            that information always has a physical representation.

            the Darwinian algorithm is implemented in a wide variety of fields outside of biology

            In other words the evolutionary products of Quantum Darwinism may be
            the classical reality in which all other Darwinian processes operate and
            produce their own evolutionary products.

              Not that I comprehend these axioms, and the interrelationships that occur. However I do see an obvious omission.

              There is no mention of phi. It's like a recipe for bread without flour. It is obviously not present.

              For a theorem to be elegant, it has to be true in all aspects of our universe, and that is why quantum mechanics stumbles, it fails to explain the macro as well as the micro. So the mechanics that randomly distributed dust in space falls together to create a universe, is the same as non biological soup falls together to create life.

              It's also obvious that we don't have the capability to understand these relationships because there is no understanding for the great nothingness in between. We think space as simply distance, and it's erroneous because I have no doubt that it will be proven that space is most likely a fabric of velocity. One where mass harnesses the energy of the movement from negative pressures in the fabric. The negative pressures allow the aggregation in the constructs of phi. How the negative pressures appear is why we are lost in overunity generation, we only perceive the end product... i.e., a loaf of bread, and don't know the ingredients of how it's made.


              Sorry to challenge crazy talk with more crazy talk... no one should think alone, that is part of the equation too.

                The visual Newtonian* universe was created from
                unseen Planck's quantum micro-world.
                We have all capability to understand their relationships.
                We need only to answer to some questions.
                For example a simple logical question:
                what is the real image of Minkowski absolute 4-D space-time?
                And . . . . . etc . . .

                  Does it make sense to try to describe a concept with another concept that might not be correct? What if the reality only existed in 5-D? Do you see what I'm saying?

                  It's not the argument that a 7 minute abs video is better than an 8 minute abs video (Something About Mary)Folly is not just for ignorant. Hawkins when trying to explain his challenges to matter being obliterated near a black hole, went into to a multidimensional spiel.

                  I'm looking for ways to exploit the vacuum (which has to be an erroneous description BTW). Isn't it strange we haven't been able to unify the relationship between the three forces, and no one questions the postulates of general relativity? If you can move faster than the speed of light, you might be able to detect it has a varied speed in different inertial planes. Tesla could prove that his wave moved faster than the speed of light. We keep placing these artificial barriers because it's at the limit of what we can describe. What do we really know?

                    If 5-D really exist then according to concept of evolution
                    it was started from 1-D, and then 2-D . . .* 27-D . . .

                      What is ''quantum'' ?
                      My opinion.
                      Planck / Einstein described ''quantum'' as ''quantum of action'': E=hf
                      where ( h) is a ''quantum of action''- particle and (f) its frequency.
                      (wave / particle duality - simultaneously )
                      Uhlenbeck and Goudsmit described how this action is possible: E=h*f
                      ( h bar = h/2pi )
