The text presents a brain-centred interpretation of quantum physics, which rejects the classical concept of objectivity in favour of a model of the co-production of reality. It describes the measurement process not as the discovery of pre-existing facts, but as a transformative process in which a continuous order is translated into discrete information. Key physical concepts such as Born’s rule and Bell’s inequalities serve here as evidence of the structural superiority of nature over our limited models. The human brain functions as a kind of interface, creating a tangible but incomplete map of reality from a complex, indivisible world. Ultimately, quantum probability is defined as the mathematical expression of this inevitable l ...
