Distortion (optics)
"In geometric optics and cathode ray tube (CRT) displays, distortion is a deviation from rectilinear projection, a projection in which straight lines in a scene remain straight in an image. It is a form of optical aberration."

Hardy's paradox
Hardy's paradox
"Hardy's paradox is a thought experiment in quantum mechanics devised by Lucien Hardy in which a particle and its antiparticle may interact without annihilating each other. The paradox arises in that this may only occur if the interaction is not observed and so it seemed that one might never be able to confirm this."
