Real-life experiment shows Niels Bohr was right in a theoretical debate with Einstein

Chinese scientists carried out an experiment first proposed by Albert Einstein almost a century ago when he sought to disprove the complementarity principle of quantum mechanics put forward by Niels Bohr and his school of physicists. Bohr claimed that there are properties of particles that cannot be measured simultaneously. The new result once again confirms the Copenhagen school, with the potential to shed light on other, less resolved questions in quantum mechanics.
