Man-Made Confusions about Identity

In the light of quantum theory these elementary particles are no longer real in the same sense as objects of daily life, trees or stones, but appear as abstractions derived from the real material of observation in the true sense. (Werner Heisenberg)

In the Copenhagen Interpretation CI of quantum mechanics as the present standard of modern physics established 100 years ago, quantum particles like electrons do not carry the physical identity of classical particles, which even of the same kind can be identified by their unique trajectories in space and time without jumps. Electrons in CI lack such physicality and appear rather as abstract possibilities than actualities. 

This makes CI into a non-physical theory impossible to visualise, a theory without Anschaulichkeit in the words of Schrödinger. This is the root of the present crisis of modern physics. 

Recent posts exhibited the complications arising from the lack of identity of the quantum particles of the CI. These are man-made complication, which do not arise in real physics where identity is not compromised. 

Complications arising from confusion of identity also arise in man-made worlds outside physics. The presence of several copies of a picture or text in the memory of the computer may cause confusion if not all copies are updated the same way. The presence of copies of works of art upsets the art market. The same with branded clothes and bags. The presence of doubles in politics adds to confusion. AI brings further confusion since author identity is missing and intellectual property has no owner. 

Quantum mechanics as man-made physics is full of complications from confusion of identity. All the troubles come from denying an electron physical identity in space and time. It is like denying a person to be citizen of a country, to condemn the person to be stateless or homeless without a passport and bank account, to be a no-person. How to handle electrons or persons without identity? 

Classical physics as real natural physics existing independent of human speculation is not man-made in the same sense and there is no lack of identity.
