Długość, szerokość i głębokość. Znajomość tych trzech parametrów pozwala oszacować, czy stół zmieści się w jadalni, a łóżko w sypialni. Posługując się trzema wymiarami do opisu przestrzeni, w której żyjemy, rzadko zadajemy sobie pytanie o jej naturę.

According to Bell’s theorem, no local realistic model can reproduce all predictions of quantum mechanics for the EPR-B experiment. Any such model would have to predict both the perfect correlation and breaking the CHSH inequality, but this seems impossible, since to provide the first prediction, the model would have to be deterministic, whereas this would seem to make the second one impossible. A model of the EPR-B experiment is presented, in which this apparent contradiction is expected to be avoided due to a deterministic chaotic mechanism underlying measurements. The model is in the phase of a “black box” model, since this mechanism is not yet specified, but only a corresponding probabilistic response function.

Quantum logic emerged in the 1930s as a response to the question of whether the conceptual changes initiated in physics by quantum mechanics required a revision of logic. In the English-language literature, John von Neumann is considered the founder of quantum logic, while the Polish literature points to Zygmunt Zawirski. Zawirski was the first researcher who suggested that quantum mechanics may follow a different logic than classical logic. He was the first researcher in the field of manyvalued quantum logic, but his influence ultimately proved to be limited. John von Neumann, on the other hand, along with Garrett Birkhoff, started the now dominant field of algebraic quantum logic. It turns out that despite their differences in assumptions and methods, what they have in common is their commitment to subjecting the design of quantum logic to two requirements - consideration of Heisenberg's indeterminacy principle and reconciliation of the resulting logic with probability calculus.
