Re: Particle Position

So in order for Jim's question to have meaning, he has to tell us what
he means by a "particle".

How "wrong" is this statement? :

When it's interacting with an atom, it's a particle. When its flying
through space it's a wave.

In other words, an electron in a box would be a wave, and wouldn't have
any point-like position. But when an electron strikes a ZnS flourescent
screen and creates a flash of light, the wave no longer exists, and the
electron is a particle.

(Also, isn't this called the "Hidden Variables" problem? If an electron
did have a real position, even though we could not know its position, then
that would be a Hidden Variables theory, and be inapplicable to QM.)
