  4. Several new physics experiments in 1998 were performed and analyzed to showthe subtlety of quantum theory, including the “ wave - particle duality ” and the nonseparability of two - particle entangled s tate. here it is shown that the measurement is bound to change the object by dest roying the original quantum coherence between the object and its environment. so the “ physical reality ” should be defined at two levels, the “ thing in itself ” and the “ thing for us ”. the wave function in quantum mechanics is just playing the role for connecting the two levels of matter via the fictitious measurement
