WebJan 23, 2024 · Da der tilmed er forskellige varianter af Københavnerfortolkningen, gik det så vidt, at den amerikanske fysiker David Mermin i 1989 nedkogte essensen til »Shut up and calculate«. Det blev meget hurtigt et populært og stadig brugt udtryk i kvantefysikkredse. I dag indrømmer Mermin dog, at udtrykket nok ikke var særlig heldigt. WebJul 8, 2024 · Photons are created when electrons make a downward transition because that is how quantum electrodynamics works, at least in this universe. At a level so fundamental, physicists, as Cornell physicist David Mermin commanded (although the maxim is misattributed to Richard Feynman and sometimes Paul Dirac), “shut up and calculate”.
