Abstract The myth about special quantum mechanics, different from classical mechanics, has been debunked. In fact, there is a branch of classical mechanics, which belongs to wave theory and considers a particle-like wave, rather than a particle having the properties of a wave. New quantum mechanics, free from unnecessary entities, assumptions, and hypotheses, makes it possible to get rid of many accumulated
