Pin It

N.D. Mermin wrote: "Why has the Aharonov group been confusing some of us in this way for two decades? There is a clue in the final section of the authors’ PHYSICS TODAY article, where they talk about the flow of time. There they suggest taking seriously the idea that time “propagates forward from the past boundary condition and backward from the future boundary condition.” If you believe that, then conventional use of tense is indeed obsolete and distracting, and using the subjunctive mood in counterfactual statements becomes problematic."

Obviously Mermin does not take this way of thinking seriously. Pity. Modern cosmology shows our past particle horizon must have a boundary condition as well as our future event horizon. If they are fractal, then all scales from Planck to Hubble are involved. Indeed, the physics on both of these 2D hologram screens is Bohm's Implicate Order with us as hologram images in the bulk 3D interior's explicate order. Seth Lloyd also thinks these observer-dependent pixelated surface horizons are computers - presumably quantum and possibly conscious?

Aharonov wrote: "However, as Mermin certainly knows, analyzing sentences in isolation without the many clues found in context doesn’t do them justice. The initial setup is indeed elementary, and we put in all the details, so it is hard to see how it could be misinterpreted. The situation becomes far more interesting and surprising, though, when weak measurements are taken into account; to ignore them, as Michael Nauenberg and Art Hobson did, is to completely miss the point. We believe that no true understanding of quantum mechanics can be obtained without taking weak measurements seriously."
