Niels Henrik David Bohr , född 7 oktober 1885 i Köpenhamn, död 18 november 1962 i Köpenhamn, var en av 1900-talets främsta atomfysiker. 1913 publicerade Bohr, inspirerad av Plancks och Einsteins arbeten, en atommodell som bortsåg från den klassiska fysikens begrepp. Modellen byggde på en hypotes om elektronernas stationära tillstånd, som svarade mot en diskret serie … WebbSummary. Niels Bohr's theory of complementarity was an attempt to solve the enormous problems of interpretation – especially the problem of wave particle duality – that beset the quantum theory in the mid-twenties. By 1920 electromagnetic radiation could be conceived of either in terms of the wave model or in terms of the particle model ...
