In my last physics course, we spent the last couple of weeks introducing quantum mechanics, covering the schroedinger wave equation and simple examples like a particle in a box. So I don't know much about QM, and this may be a stupid question. Anyway, we were taught that the particle can be thought of as a wave, described by the wave equation. Then they said the interpretation of the wave equation is that the integral of its magnitude squared over a region is the probablity of finding the particle in that region. So which is it? Is the particle some speck that can be anywhere, but is likely to be in the regions of high probability? Or is it the wave itself?
