Uncertainty principle is not a ‘principle’


"Nor, by the way , is the uncertainty principle a ‘ principle’ , for that suggests an independent postulate that could logically be dropped or replaced to obtain a different theory . In fact one could no more drop it from quantum theory than one could omit eclipses from astronomy . There is no ‘ principle of eclipses’ : their existence can be deduced from theories of much greater generality , such as those of the solar system’s geometry and dynamics. Similarly , the uncertainty principle is deduced from the principles of quantum theory ."
