Experiments in Quantum mechanics have three practically independent stages: ''preparatory'', ''theoretical'', and ''measuring''. The ''theoretical'' one is based on the Schredinger Equation which determines the particle's state in different moments of time before measurement. Even if one uses the standard probabilistic interpretation of a wave function one can show that the Schredinger Equation describes possible trajectories of a quantum particle and speeds of this particle on the trajectories. The mathematical development of this approach leads to the idea that during the motion of an electron in an atom the structures are formed in the physical vacuum.
