preprint description
This article introduces the method of protective measurement and discusses its deep implications for the foundations of quantum mechanics. It is argued that protective measurement implies that the wave function of a quantum system is a representation of the physical state of the system, and a further analysis of the mass and charge distribution of the system, which is measurable by protective measurements, may also help determine what physical state the wave function represents.
