Philosopher of physics to physicists: Calculate, but don’t shut up

BA77,

Of personal note on Wigner. A Darwinist tried to claim that Wigner was, of all things, an atheist. As with so many other things that atheists claim, that claim turned out to be a false claim:

I wonder who that was? :-) BTW, the person who made that claim was not a Darwinist. daveS

My view is that when you get to the bottom turtle, there is no physical reality to understand. There is only Mind that chose the mathematical foundation of physical reality. At that level, all you can do is calculate. Jim Smith

The quote, "Shut up and calculate", has an irrational fear behind it:

"If I were forced to sum up in one sentence what the Copenhagen interpretation says to me, it would be 'Shut up and calculate!'" - What's Wrong with this Pillow? by N. David Mermin, Cornell University, Physics Today, April 1989, page 9, doi:10.1063/1.2810963 Misattributed to Richard Feynman, http://en.wikiquote.org/wiki/David_Mermin

The irrational fear behind the 'shut up and calculate' quote is highlighted here

Quantum state may be a real thing: Physicists summon up their courage and go after the nature of reality. by Chris Lee - Jul 2, 2014 Excerpt: At the very heart of quantum mechanics lies a monster waiting to consume unwary minds. This monster goes by the name The Nature of Reality™. The greatest of physicists have taken one look into its mouth, saw the size of its teeth, and were consumed. Niels Bohr denied the existence of the monster after he nonchalantly (and very quietly) exited the monster's lair muttering "shut up and calculate." Einstein caught a glimpse of the teeth and fainted. He was reportedly rescued by Erwin Schrödinger at great personal risk, but neither really recovered from their encounter with the beast. http://arstechnica.com/science/2014/07/02/quantum-state-may-be-a-real-thing/

Feynman, besides not saying the infamous 'shut up and calculate' quote, appears to have had a much 'braver' attitude about the situation with quantum mechanics and with facing reality head on no matter what the evidence said:

…the “paradox” is only a conflict between reality and your feeling of what reality “ought to be.” Richard Feynman, in The Feynman Lectures on Physics, vol III, p. 18-9 (1965)

Ironically, it is impossible to merely 'shut up and calculate' with quantum mechanics because the calculations of quantum mechanics refuse to be done without the 'weirdness' of quantum mechanics intruding full force into your calculations:

Does Quantum Physics Make it Easier to Believe in God? Stephen M. Barr - July 10, 2012 Excerpt: Couldn’t an inanimate physical device (say, a Geiger counter) carry out a “measurement” (minus the 'observer' in quantum mechanics)? That would run into the very problem pointed out by von Neumann: If the “observer” were just a purely physical entity, such as a Geiger counter, one could in principle write down a bigger wavefunction that described not only the thing being measured but also the observer. And, when calculated with the Schrödinger equation, that bigger wave function would not jump! Again: as long as only purely physical entities are involved, they are governed by an equation that says that the probabilities don’t jump. That’s why, when Peierls was asked whether a machine could be an “observer,” he said no, explaining that “the quantum mechanical description is in terms of knowledge, and knowledge requires somebody who knows.” Not a purely physical thing, but a mind. https://www.bigquestionsonline.com/content/does-quantum-physics-make-it-easier-believe-god The Measurement Problem in quantum mechanics – (Inspiring Philosophy) – 2014 video https://www.youtube.com/watch?v=qB7d5V71vUE

Also of note, Wigner, instead of 'shutting up and calculating', looked at the situation with quantum mechanics and developed a entirely new method of calculations called 'quantum symmetries'. Here is Wigner commenting on the key experiment that led Wigner to his Nobel Prize winning work on quantum symmetries,,,

Eugene Wigner Excerpt: When I returned to Berlin, the excellent crystallographer Weissenberg asked me to study: why is it that in a crystal the atoms like to sit in a symmetry plane or symmetry axis. After a short time of thinking I understood:,,,, To express this basic experience in a more direct way: the world does not have a privileged center, there is no absolute rest, preferred direction, unique origin of calendar time, even left and right seem to be rather symmetric. The interference of electrons, photons, neutrons has indicated that the state of a particle can be described by a vector possessing a certain number of components. As the observer is replaced by another observer (working elsewhere, looking at a different direction, using another clock, perhaps being left-handed), the state of the very same particle is described by another vector, obtained from the previous vector by multiplying it with a matrix. This matrix transfers from one observer to another. http://www.reak.bme.hu/Wigner_Course/WignerBio/wb1.htm

i.e. In the experiment the 'world' (i.e. the universe) does not have a ‘privileged center’. Yet strangely, the conscious observer does exhibit a 'privileged center'. This is since the 'matrix', which determines which vector will be used to describe the particle in the experiment, is 'observer-centric' in its origination! Wigner went on to state:

"It was not possible to formulate the laws (of quantum theory) in a fully consistent way without reference to consciousness." Eugene Wigner (1902 -1995) from his collection of essays "Symmetries and Reflections – Scientific Essays" "It will remain remarkable, in whatever way our future concepts may develop, that the very study of the external world led to the scientific conclusion that the content of the consciousness is the ultimate universal reality" - Eugene Wigner - (Remarks on the Mind-Body Question, Eugene Wigner, in Wheeler and Zurek, p.169) 1961 - received Nobel Prize in 1963 for 'Quantum Symmetries'

Of supplemental note to the preceding Wigner 'consciousness' quotes, it is interesting to note that many of Wigner's insights have now been experimentally verified and are also now fostering a 'second' revolution in quantum mechanics,,,

Eugene Wigner – A Gedanken Pioneer of the Second Quantum Revolution - Anton Zeilinger - Sept. 2014 Conclusion It would be fascinating to know Eugene Wigner’s reaction to the fact that the gedanken experiments he discussed (in 1963 and 1970) have not only become reality, but building on his gedanken experiments, new ideas have developed which on the one hand probe the foundations of quantum mechanics even deeper, and which on the other hand also provide the foundations to the new field of quantum information technology. All these experiments pay homage to the great insight Wigner expressed in developing these gedanken experiments and in his analyses of the foundations of quantum mechanics, http://epjwoc.epj.org/articles/epjconf/pdf/2014/15/epjconf_wigner2014_01010.pdf

Thus, since Wigner’s insights into the foundational role of the ‘conscious observer’ in Quantum Mechanics are bearing fruit with a ‘Second Quantum Revolution’, then that is certainly very strong evidence that his ‘consciousness’ insights are indeed true for reality. Of personal note on Wigner. A Darwinist tried to claim that Wigner was, of all things, an atheist. As with so many other things that atheists claim, that claim turned out to be a false claim:

"So the Wigners easily became Lutherans. Today I am only mildly religious. When I attend church it is with the protestants.,,, I found Karl Marx quite unconvincing. And Lenin was even worse." Eugene Wigner - Recollections - page 39 - 1992

of semi-related note to an observer being needed in quantum mechanics in order to complete the measurement of a system, a 'hypothetical observer' with a 'distinct frame of reference' was key to Einstein's breakthrough insights for relativity in his thought experiments:

Introduction to special relativity Excerpt: Einstein's approach was based on thought experiments, calculations, and the principle of relativity, which is the notion that all physical laws should appear the same (that is, take the same basic form) to all inertial observers.,,, Each observer has a distinct "frame of reference" in which velocities are measured,,,, http://en.wikipedia.org/wiki/Introduction_to_special_relativity Albert Einstein - Special Relativity - Insight Into Eternity - 'thought experiment' video https://vimeo.com/93101738 Einstein - General Relativity - Thought Experiment - video https://vimeo.com/95417559

'Scientists have become the bearers of the torch of discovery in our quest for knowledge. —Stephen Hawking and Leonard Mlodinow.' Who would have thought Hawking would be in thrall to scientism, of all things barmy. Well, at least until he demonstrated his dire need of the merest trace of an innate philosophical cast of mind, by his postulation that the laws of physics could have created the universe ! Axel
