The Copenhagen Interpretation: Observers Shape Reality

The Copenhagen interpretation is the oldest and most widely taught view of quantum mechanics.
It was developed in the 1920s by Niels Bohr and Werner Heisenberg.
It claims quantum systems exist in superpositions until observed.
Measurement forces the system to “collapse” into one definite outcome.
Reality, in this view, isn’t fixed until an observation takes place.
It highlights the central role of the observer in shaping quantum events.
Schrödinger’s Cat paradox was designed to poke holes in this interpretation.
Despite criticisms, it matches experimental results remarkably well.
It avoids hidden variables, accepting probability as fundamental to nature.
The Copenhagen view remains a cornerstone of how many physicists understand quantum reality.
