Despite its success\, however\, the conc epts of reality and local causality are deeply problematic in quantum mech anics. Such problems may lie at the heart of why it has been so difficult to synthesise quantum and gravitational physics. \nMotivated by these issu es\, we apply Planck’s discretisation insight again\, but this time to t he continuum of quantum mechanics’ state space - complex Hilbert Space. A particular discretisation is discussed - one which draws on number theor etic properties of trigonometric functions. This leads to a model of quant um physics which is necessarily superdeterministic in character\, that is to say violates the Statistical Independence assumption in Bell’s Theore m. Because of this\, the model does not need to invoke concepts of indefin ite reality or nonlocality to explain the violation of Bell’s inequality \n LOCATION:https://researchseminars.org/talk/QMFNoT/27/ END:VEVENT END:VCALENDAR
