:Hi Alexander, no problem about the misunderstandingbut why do you say that there is a mistake in the quote "but that this argument ..."? The sentence as it stood was grammatically correct, and it correctly summarized Winful's view that the reshaping argument is incorrect because it isn't supported by experiments or simulations (I quoted from p. 12-13 of this paper where Winful writes Unfortunately this argument is supported neither by the experimental observations [19,20] nor by simulations [21].) Perhaps the sentence would be clearer if I changed it to this:Herbert Winful argues that the train analogy is a variant of the "reshaping argument" for superluminal tunneling velocities, but he goes on to say that this argument is not actually supported by experiment or simulations, which actually show that the transmitted pulse has the same length and shape as the incident pulse.Then if you like you can add a separate sentence pointing out that Longhi and Nimtz also argue that the reshaping argument is incorrect, even if they don't agree with Winful about his own separate argument for why tunneling doesn't violate the speed-of-light limit. Would this be a satisfactory compromise?
