MOS: Balloons? Okay, you get all the fun, ha. QW: Single Photon Experiment seems to have weird conclusions: http://abyss.uoregon.edu/~js/21st_century_science/lectures/lec13.html "The formation of the interference pattern requires the existence of two slits, but how can a single photon passing through one slit `know' about the existence of the other slit? We are stuck going back to thinking of each photon as a wave that hits both slits. Or we have to think of the photon as splitting and going through each slit separately (but how does the photon know a pair of slits is coming?). The only solution is to give up the idea of a photon or an electron having location. The location of a subatomic particle is not defined until it is observed (such as striking a screen)." [End of quote] QW: That certainly sounds like the science is settled; they ask how a single photon can go through both slits, and conclude it can't, saying, "The only solution is to give up the idea of a photon or an electron having location." "At least not unless the photon can somehow know there are two slits ahead", and suggests in that case that "maybe the particles split themselves in two, "the location is not defined until observed". It reminds me of the conclusion from the Bell Inequalities experiments that conclude that there can be no local reality unless we accept faster than light communications, i.e., the particles somehow "know" when the state of the other one is determined, and then respond. I think there is natural, consistent law that determines those things, and we have to keep looking for the mechanisms. See the next link below. Here is good solution, and it is much like what I propose in my model: http://phys.org/news/2011-06-quantum-physics-photons-two-slit-interferometer.html "That famous experiment, and the 1927 Neils Bohr and Albert Einstein debates, seemed to establish that you could not watch a particle go through one of two slits without destroying the interference effect: you had to choose which phenomenon to look for. "Quantum measurement has been the philosophical elephant in the room of quantum mechanics for the past century," says Steinberg, who is lead author of Observing the Average Trajectories of Single Photons in a Two-Slit Interferometer, to be published in Science on June 2. "However, in the past 10 to 15 years, technology has reached the point where detailed experiments on individual quantum systems really can be done, with potential applications such as quantum cryptography and computation." With this new experiment, the researchers have succeeded for the first time in experimentally reconstructing full trajectories which provide a description of how light particles move through the two slits and form an interference pattern. Their technique builds on a new theory of weak measurement that was developed by Yakir Aharonov's group at Tel Aviv University. Howard Wiseman of Griffith University proposed that it might be possible to measure the direction a photon (particle of light) was moving, conditioned upon where the photon is found. By combining information about the photon's direction at many different points, one could construct its entire flow pattern ie. the trajectories it takes to a screen. "In our experiment, a new single-photon source developed at the National Institute for Standards and Technology in Colorado was used to send photons one by one into an interferometer constructed at Toronto. We then used a quartz calcite, which has an effect on light that depends on the direction the light is propagating, to measure the direction as a function of position. Our measured trajectories are consistent, as Wiseman had predicted, with the realistic but unconventional interpretation of quantum mechanics of such influential thinkers as David Bohm and Louis de Broglie," said Steinberg. The original double-slit experiment played a central role in the early development of quantum mechanics, leading directly to Bohr's formulation of the principle of complementarity. Complementarity states that observing particle-like or wave-like behaviour in the double-slit experiment depends on the type of measurement made: the system cannot behave as both a particle and wave simultaneously. Steinberg's recent experiment suggests this doesn't have to be the case: the system can behave as both." [End of quote] QW: I have proposed that the photon has both its wave and particle states at all times; the high density spots establish its location, and the direction of the inflowing wave energy determines the direction where the next set of spots will form. It depends on our method of observations as to which state we observe. This article seems to agree, and suggests they have the beginnings of physical evidence.
