The understanding that the photon wave function can be calculated from Maxwell's equations is not fringe physics. It was asserted, emphatically, by our newest Nobel laureate, Roger Penrose. Have you read his statement? Do you think he was wrong?

Subsequently, Mohr, at the National Institute of Science and Technology proved, in abundant detail, exactly what Penrose first stated. Have you read the article by Mohr? Do you believe that's fringe physics? What about the article by Smith and Raymer at Oxford? Have you read it? It too shows, in a very careful analysis, exactly what Penrose taught us. If you are not yet familiar with this work, that does not make it fringe physics.

No doubt, there are established physicists who wish to ignore the implications, published years ago, of the work of these respected researchers. The assertion of equivalence between the photon wave function and the solution to Maxwell's equations shows some of our colleagues, including Afshar, were decisively wrong. That doesn't make it fringe physics. Unless we incorporate the best current explanations we are condemned to remain mired in the quagmire of the many conflicting, confounding quantum measurement proposals that inhibit progress. The assertion by Penrose, Smith and Raymer, and Mohr, does the opposite: it points the way to a realistic understanding.

From a somewhat different perspective, Andrew Knight, in the Revs. Mod. Physics, has just emphasized, again, the need to critically evaluate the errors in the Afshar proposal if we wish to advance quantum physics. My own contribution to the Afshar page merely stated the logical, rational result of applying the Penrose 'equivalence principle' to the Afshar experiment. Since we now know, precisely, the evolution of the photon wave function, random absorption of the photon at just one of the detectors cannot provide which-way information. It is not fringe physics to promulgate that now obvious reality. Protecting the status quo is not an avenue to understanding. D bar x (talk) 05:10, 8 December 2020 (UTC)
