What Is a Particle if It Is a Wave?
So far we have been talking about waves. We have also seen that typical particle aspects such as energy and momentum also can be carried by waves. We have claimed that all of us are waves in the vacuum. However, this does not yet give us an idea how a particle can ever be a wave. When we imagine a particle, we see a little ball, located at a particular position at a specific time and propagating at a particular velocity. If particles are to be represented by waves, then we must be able to get these properties from the waves. Only then can we understand how we can see (=measure) a particle while we are actually dealing with waves.
