Why did Werner Heisenberg dislike this theory on electron movement?

Werner Heisenberg disliked the classical theory of electron movement because it could not accurately describe the behavior of electrons at the quantum level. Classical mechanics suggested that electrons should move in well-defined orbits around the nucleus, but this contradicted experimental evidence, such as the stability of atoms and the discrete energy levels observed in atomic spectra. Heisenberg favored a probabilistic approach, leading to the development of quantum mechanics, which allowed for a more accurate description of electron behavior as wave functions rather than fixed paths. This shift represented a fundamental change in understanding the nature of particles and their interactions.
