The Copenhagen interpretation is a consensus among some of the pioneers in the field of quantum mechanics that it is undesirable to posit anything that goes beyond the mathematical formulae and the kinds of physical apparatus and reactions that enable us to gain some knowledge of what goes on at the atomic scale .
The Copenhagen interpretation is what one group of the pioneers of quantum mechanics thought -- that it is not useful to say anything that goes beyond the math , the equipment , and the real results that let us to get some idea of what goes on at the atomic scale .
