Rejection of my article "Why pure quantum theory is not enough" (arXiv:0903.4657) by "Foundations of Physics"

It is not open rejection (with arguments) but simple ignorance which characterizes the reaction of the mainstream of physics to my theories. So I'm happy even with some rejections of publications: They at least give me some reaction, even if it is a negative one.

But in this particular case, the "rejection" is quite positive. Of course, this doesn't increase the number of my peer-review published papers. But, fortunately, I do not have to care about this number. The part of the peer-review process which is important for me has been answered positively:

… the paper fulfills the first requirement asked to the referee [Is the paper technically correct and accurate?] … (referee report)

In this sense, the submission has been successful.

And we can have some fun recognising that it is technically correct and accurate, but nor a novel result, nor of much interest for the readers of "Foundations of Physics", that many popular interpretations of quantum theory, in particular many worlds and consistent histories, as well as the decoherence program should be given up:

If one follows the arguments of this paper, the program of developing pure quantum interpretations has to be given up. One can save particular pure interpretations only by introducing an additional physically motivated structure. As a consequence, they loose one of their most attractive features — their purity.
… In particular, we have to include here the modern variants of many worlds, other Everett-like interpretations, and decoherent histories (see [25] for some overview), Mermin's Ithaca interpretation [13], and what Wallace [25] has named "new pragmatism".
… In particular, the popular idea that decoherence can be used to fix a preferred set of observables is false. (the paper)

We have been also surprised to find Mermin's Ithaca interpretation, explicitly mentioned as a pure interpretation in the paper, implicitly classified in the report as a variant of the Everett interpretation – a really nice insider joke.

… The pure interpretations are Everett's relative state interpretation and its variants. … (referee report)

Dear Ilja Schmelzer,

We have received the reports from our advisors on your manuscript FOOP1026 "Why pure quantum theory is not enough".

With regret, I must inform you that, based on the advice received, the Editors have decided that your manuscript cannot be accepted for publication in Foundations of Physics.

Below, please find the comments for your perusal.



I would like to thank you very much for forwarding your manuscript to us for consideration and wish you every success in finding an alternative place of publication.


With kind regards,

Gerard 't Hooft
Chief Editor


Comments for the Author:



Editorial comment: if, as advised by the referee, the author decides to write a brief paper on this topic, it may be submited to this Journal as a Letter and it may be reconsidered.

Reviewer #1: The paper departs from some consequences from the theory of the KdV equations, demonstrated in a previous paper by the same author, to demonstrate that these consequences are problematic for "interpretations of quantum theory which reject the classical part of the Copenhagen interpretation, but do no add an appropriate replacement to it's quantum part." The main purpose of the author is thus to show that "The ideal of a 'pure interpretation' of quantum theory, which does not add anything to the quantum part, but allows to derive the classical part, has to be given up." The pure interpretations are Everett's relative state interpretation and its variants. In the previous paper, cited in the submitted manuscript, the author has shown that the theory of KdV equations implies "that the Hamilton operator alone is not sufficient to fix the physics."

As the author acknowledged that the manuscript is a follow-up of the previous paper, by the way published in Foundations of Physics [FofP], I have analyzed and compared both, trying to figure out what the main new developments were. Unfortunately, as far as I was able to make such a comparison I do not think that the additions should justify anew paper in FofP. Indeed, the physical ideas are the same, and the manuscript only extends the points already expressed.

The author, himself, justified the paper in the sense I have interpreted it, as he wrote, while discussing with one of the referees: "Reading in the referee report 'I think no one will argue that his conclusion is incorrect, but for some of the committed many-worlds people with whom he is contending' has left me with a feeling of unease. On the one hand, it is nice to read that your conclusions are correct. On the other hand, there was a feeling that my conclusions have not been strong enough, that these examples are problematic not only for some particular opinions of some of the many worlders." Indeed, while the paper fulfills the first requirement asked to the referee [Is the paper technically correct and accurate?] it does not meet the next requirement [Does it contain novel results and do you consider it of interest to readers of Foundations of Physics?]. I do not think that a paper to strengthen conclusions from a previous paper published in the same journal is suitable to be published in FofP.

Therefore I would suggest the author to write a short and concise letter stating the main points he thinks were misunderstood or not enough stated in the previous paper and submit it to the editor of this journal.
