Over-moderation makes arXiv.org another refereed journal

I just so happened to stumble upon a very interesting comment on arXiv’s moderation issues (certainly more interesting than the original blog article). I could not agree more with the commenter. It is almost exactly like what I would like to write about the issue but probably not as well as the anonymous commenter articulated. In particular, I made similar comparisons between science and business; startup companies vs. researchers with risky/novel scientific ideas, etc. I can not help but fully quote the comment here,

New paper on first principles

I just tried to post my new paper of “First Principles of Consistent Physics” on arXiv.org. Unfortunately it was put on hold immediately and I then submitted it to the OSF eprint server. This is quite an exciting paper to me. It proposes new foundations and guiding principles on fundamental physics and cosmology based and improved upon my early blog “first principles of physics“. It should shed new light on further developments of the new mirror framework.

First principles of physics

The approach of first principles has been pursued in the development and history of physics. Ever since the establishment of the Standard Model of particle physics in 1970s, the idea of going after theory of everything has become popular as the latest approach of first principles among theoretical physicists for unifying all particles and interactions. However, we seem to live in a dynamic world as indicated, e.g., since the discovery of an expanding Universe and it is definitely at odds with the static picture of an ultimate unified theory for physics.

The dynamic picture tells us that the time reversal symmetry has to be broken and it has to be the first (broken) symmetry. Whatever first principles we propose have to be able to naturally break this symmetry first in the very beginning. And there is no reason why the current 4-dimensional spacetime, in particular, its dimensions can’t be dynamic. It is probably more natural to consider that spacetime has evolved in a dimension-by-dimension way.

First of all, we propose and summarize the three first principles as follows:

  1. A measurable finite physical world is assumed.
  2. The quantum version of the variation principle in terms of Feynman’s path integral formalism is applied.
  3. Spacetime emerges via dimensional phase transitions (i.e., first time dimension and then space dimensions got inflated).

How should private foundations support science?

It is amazing that there exist quite some private foundations in the United States who care about science and are enthusiastic about funding scientific projects. However, a lot of them, if not all, don’t seem to know how they should support science in a complementary way when compared to government funding agencies like NSF and DoE.

Time to reform peer-review

One of the critical features in scientific research is the application of the so-called peer-review process before a scientific paper is officially published in a journal. Ideally, peer-review, at least seemingly in its original purpose, should serve as a measure of quality control that benefits both the authors and the readers. However, nowadays, it becomes more and more like an obstruction to the advancement of science, in particular, in terms of radically new ideas and directions.

How can a new idea be accepted by eminent physicists?

In a nostalgic review article titled “Twenty years of the Weyl anomaly” [Michael J Duff, Class. Quantum Grav. 11, 1387 (1994)], Duff recalled the history of his discovery of the Weyl or conformal anomaly in quantum theory with Derek Capper.

Old Wine in New Bottles - How does science advance?

A lot of times science advances by incorporating or interpreting old ideas under new scenarios.

For example, Lorentz first proposed the so-called Lorentz transformation, but it was Einstein who correctly interpreted and applied it in his theory of special relativity. Yang and Mills first came up with the SU(2) gauge theory idea for studying nuclear isospin. But it was Glashow, Weinberg, Salam , and ‘t Hooft who found the best application of the idea to the electroweak interaction eventually leading to the most celebrated unification theory (called the Standard Model) for all three gauge interactions of the known elementary particles.

A possible solution to arbitrary evaluations
