Wave-Particle Duality: Particle Always Remains Particle and Its Wave Function Always Remains Wave

On the question of wave-particle duality, from historic Bohr-Einstein debates a century ago, to this day, view expressed in Niels Bohr’s Complementarity Principle has become well established, confirmed by numerous experiments: If observation is for wave nature, then particle changes wave, and if remains particle. However, recently been challenged. With proof based on definition function, it shown that always its function no mysterious change vice versa.
