When classical mechanics is seen as the short-wavelength limit of quantum mechanics (i.e., as the limit of geometrical optics), it becomes clear just how serious and all-pervasive the measurement problem is. This formulation also leads us into the Bohm theory. But this theory has drawbacks: its nonuniqueness, in particular, and its nonlocality. I argue that these both reflect an underlying problem concerning information, which is actually a deeper version of the measurement problem itself.
I thank Bas van Fraassen for aid and encouragement in writing this paper. I am also indebted to Tim Maudlin and to other members of the quantum mechanics discussion group, which met in Princeton during the spring of 1992, for their clear formulations of the measurement problem and related issues.
