At the end of the 1920s, [[Niels Bohr]], [[Werner Heisenberg]], and [[Wolfgang Pauli]] had worked out the [[Copenhagen interpretation]] of quantum mechanics, but it was rejected by Planck, and by Schrödinger, Laue, and Einstein as well. Planck expected that [[Schrödinger equation#Particles as waves|wave mechanics]] would soon render quantum theory {{snd}}his own child{{snd}} unnecessary. This was not to be the case, however. Further work only served to underscore the enduring central importance of quantum theory, even against his and Einstein's philosophical revulsions. Here Planck experienced the truth of his own earlier observation from his struggle with the older views during his younger years: "A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it."<ref>Quoted in Thomas Kuhn, ''[[The Structure of Scientific Revolutions]]'' (1970 ed.): p. 150.</ref>
