Conceptual difficulties have plagued quantum mechanics since itsinception, despite its extraordinary predictive successes. The basicproblem, plainly put, is this: It is not at all clear what quantummechanics is about. What, in fact, does quantum mechanics describe?

The ontology of de Broglie–Bohm theory consists of a configuration of the universe and a pilot wave . The configuration space can be chosen differently, as in classical mechanics and standard quantum mechanics. Thus, the ontology of pilot-wave theory contains as the trajectory we know from classical mechanics, as the wavefunction of quantum theory. So, at every moment of time there exists no… WebThermal velocity (electrons) 1.17e+6 [m s^-1] Sound speed (electrons) 7.30e+5 [m s^-1] Sound speed (ions) - Bohm velocity: 2.68e+3 [m s^-1] Thermal velocity (neutrals) … peaky blinders clothes for men
