ABSTRACT
The interpretation of quantum mechanics has been a source of conflict ever since its emergence in the 1920s. Schrödinger, de Broglie and Einstein were all of a realistic inclination, whereas Bohr, Heisenberg and several others claimed that the then new theory could not be viewed as a ‘literal’ description of nature. As the debate continued, the view held by Bohr and Heisenberg, the Copenhagen interpretation, became established among physicists and philosophers. However, the issue has never been finally settled and opponents have repeatedly voiced their doubts. During the last 20 years, the majority view, i.e. the Copenhagen interpretation, has lost ground to alternative interpretations.
