Why have so many physicists shrugged off the paradoxes of quantum mechanics?

And no other theory is so weird: Light, electrons, and other fundamental constituents of the world sometimes behave as waves, spread out over space, and other times as particles, each localized to a certain place. But for most physicists, says Becker, the Copenhagen interpretation amounted not to a carefully considered philosophical position but to a permission slip for dismissing questions, a sort of bar room putdown: Why worry about things you can’t see — such as whether, when you’re not looking, a light beam is made of particles or waves? Quantum mechanics arose when certain puzzling phenomena seemed explicable only by supposing that light, firmly established by Maxwell’s theory of electromagnetism as a wave, was acting as if composed of particles.
