19 Schrödinger puzzles

These quantum crosswords have, by design, more than one correct answer

Schrödinger equation
Erwin Schrödinger

Is it a wave or a particle? Sometimes, the answer is, yes. Or both.

Joon Pahk suggested the name for these puzzles, based on Erwin Schrödinger's poor cat who was either alive or dead. Or, more accurately, both alive and dead. Either answer is true. This sort of thing can happen when the strange world of the quantum impinges on our prosaic macro existence. And, as seen here, it also happens in crosswords.
