Apropos of these statements, but a bit off topic; several years ago I put a
couple of orthogonally opposed polarizers over the headlights of my car,
they were about two feet apart (Series IIA Land Rover). I put on glasses
having the same alignment, and looked around. The only thing I saw which
held the polarization was a single spike in a phone pole, a long half block
away. I could tell EXACTLY where that spike was relative to the pole, what's
more, the pole appeared dimensionally curved at that point. It was a very
odd sensation, having that enormous depth resolution of a small object at
that distance. Like an itch you can't scratch, it was... weird!
