I don't know if this is what the original poster meant, but: certainly, the human eye cannot directly observe stresses in structural members of bridges. But it seems quite plausible that the human *mind* could learn to "see" those stresses, in some sense, after being trained by a VR system. I know that, as a computer programmer, I can now "see" logic and structure when looking at a program, whereas a person who doesn't know how to program would see only meaningless words and letters arranged in hierarchical patterns. My ability to "see" those things came from programming for a long time, until my mind became so accustomed to programming that the interpretation of a program became a somewhat unconscious process, performed automatically by my brain whenever I see code. It's similar to when I first learned to read. At first, of course, it was a struggle, but eventually I crossed a line and it became almost like "living" the book. I remember many times when I would forget that I was reading, and not even be conscious of seeing words in front of me: my brain had become good enough at reading that the words were automatically transformed into a visual and auditory experience before my conscious mind even realised that they were there. Unfortunately, nowadays my critical faculties have become so developed (overdeveloped?) that it takes a *really* good book to do this to me; but that's another story. Given this sort of thing, is it really completely implausible that engineers could "see" structural flaws, stresses, etc? I don't know, maybe the better ones already do! It wouldn't really surprise me at all. Magnetic fields seems a bit more out-to-lunch, since they're not as easy to guess from straight sensory data of other kinds, but perhaps, in some contexts, it would be possible. I think that this kind of thing is really quite interesting, and doesn't deserve to be jumped on so aggressively by the previous poster. -Ben Haller (deadman@garnet.berkley.edu) "See me...feel me...touch me..." - The Who
