Editor, Physics Today 335 East 45 Street New York, NY 10017 U.S.A. Toruń, Dec. 1st, 1993 Dear Sir, I am deeply worried with the way science in general and physics in particular, is developing. I will mention only two reasons in this letter, refering to cases based on my personal experience. For a few years I have worked on the foundations of physics. This field has been very active in the past decade and I enjoyed going to conferences and thinking about quantum paradoxes. In 1989 I wrote a paper "Complementarity, Superluminal Telegraph and the Einstein-Podolsky-Rosen Paradox". In this paper I have proposed to measure correlations between pairs of particles in a double Mach-Zehnder experiment. Unfortunately I had not time or energy to push the paper through the refereeing procedure. I did send it to two journals and then gave up. Referees found it "seriously flawed" and "completely wrong". I have found that philosophical preferences are sufficient to stop a publication of papers in foundation of physics. Since it is hard to find two people with the same philosophical preferences chances of publication of new ideas are slim. I kept the paper on my list of references as "to be published" and decided to work on other problems. In the September issue of Scientific American the paper "Faster than Light" by R.Y. Chiao, P.G. Kwiat and A.M.Steinberg describes exactly the experiment I proposed much earlier, even the figure with the experimental setup differs very little. Well, the truth finally wins, especially when it is supported by experiment, not just theorizing. Is life easier for people working in applied quantum mechanics? Recently I was surprised to see that the editor of a major scientific journal treated seriously a two-sentence referee report about 40-pages long paper, report containing a general remark that there were too many tables and figures. I could quote many more problems related to the refereing system but we all know them only too well. The second reason that makes me worrried about the development of science is the incredible inertia that most scientist show. We are too busy working to find the time for thinking. We learn at the universities standard methods of physics and we teach these methods to our students. We improve the methods and apply them to new phenomena but who tries to question and develop fundamentally new approaches in science? Some years ago I have tried to understand whether the picture of the vacuum filled with virtual particles, the picture creating well-known problems with the density of energy of the vacuum, is just an artefact of the perturbative description or whether it has some deeper foundations. I have found three thick volumes written at the end of 60-ties by Julian Schwinger, called "The source theory", treating the vacuum as empty. In vain have I tried to find an QED expert that read it. Asking about it provoked remarks like "Oh, you are interested in non-standard approaches". If Schwinger, after creating QED, was not succesful to influence the course of its further development, who will? This year I had the pleasure to hear a seminar by Sir F. Hoyle on the new cosmological model that he and his collaborators propose. As for all scientific models it should be judged on the basis of its merit, potential for falsification and its predictive power. The reaction of some young astronomers I have talked to was quite negative ("we don't believe him", said one of them). They are too busy counting their radio sources to have the time for thinking. Is the creative thinking about fundamental models in physics reserved only for retired physicists? Those that were heretic all their life stay heretic, but are we educating heretics, are we encouraging our students to explore not only the mainstream theories but also alternatives? Or maybe physics is already too sophisticated for the human mind and we have reached the end of our abilities to comprehend the world, each individual being able to learn only limited number of theories? Sincerely yours, Wlodzislaw Duch I've got a reply, something like "True, but what can we do about it ... ".
