Approximation Method/Qualitative Difficulties/Feyerabend: E.g. reduction of the wave packet (I 82), heliocentric theory at the time of Galileo, ad-hoc approximations to many quantitative results of the theories are not correct and surprisingly qualitatively inadequate. E.g. von Neumann: replaced the semi-intuitive concepts of Dirac and Bohr with incredibly complicated concepts. The relation to experience becomes more obscure than ever.
