Mind–body dualism point into the traditionally viewed closed system, where a scientifically described physically probable/improbable event could be philosophically described as an action of a non-physical entity on physical reality. He states, however, that none of the arguments in his book will rely on this. It should also be noted that, while some interpretations of quantum mechanics consider wave function collapse to be indeterminate, in others this event is defined and deterministic. The argument from physics is closely related to the argument from causal interaction. Many physicists and consciousness researchers have argued that any action of a nonphysical mind on the brain
Two-photon physics two-photon physics experiments can be used as ways to study the photon structure, or, somewhat metaphorically, what is "inside" the photon. There are three interaction processes: For the latter two cases, the scale of the interaction is such as the strong coupling constant is large. This is called "Vector Meson Dominance" (VMD) and has to be modelled in non-perturbative QCD. Two-photon physics Two-photon physics, also called gamma–gamma physics, is a branch of particle physics that describes the interactions between two photons. Normally, beams of light pass through each other unperturbed. Inside an optical material, and if the intensity of the
