The postulate of quantum mechanics as

process as uncontrollable affects the measured physical system. This implies that a scientific theory is consistently limited to describe the outcome of any comment without trying to find an ultimate truth in nature. In this spirit that built the Quantum Mechanics (MC). It is an epistemological revolution.

1) How do you describe a quantum system?

Classical physics describes nature through their observable. For example, Newton's equations describe the position of a particle. The MC, however, describes the information of a physical system through the call wave function. For a prediction of an observable, we must act with an operator representing the observable on the wave function. The wave function itself is not observable.

2) How is an observable in MC?

An observable corresponds to a self-adjoint operator that can act on the wave function of the system. Is the mathematical representation of a meter.

3) Is it possible to find any results when measuring an observable?

Part No. the postulate of the measure dictates that the possible outcomes when measuring an observable are the eigenvalues \u200b\u200bof the operator representing the observable.

4) Do I have to believe me?

The MC is based on a few unprovable assumptions. A long process has led to reductionist them. If they are correct or not should be decided based on the systematic verification of the predictions that follow. If we find experiments that contradict these principles should be abandoned. Throughout this century has not found any experiment that contradicts the MC.

5) When I measure an observable, is always the same?

No. The second part of measurement postulate dictates that when making an observation we get one of the eigenvalues \u200b\u200bof the operator representing the observable with a certain probability (calculated as the square modulus of the projection of the wave function of the eigenvector, is easier to write the corresponding formula!). The result is thus probabilistic.

6) "The world is not deterministic?

Right. Laplace's determinism is superseded by the postulate of the measure. There is an inherently random element in the measurement process. These are not imperfections of the apparatus of statistical errors or anything fitting. The process measure, as the MC, is inherently probabilistic.

7) What happens after you measure?

The wave function collapses to the eigenvector associated with the outcome. Then evolves deterministically according to Schrödinger's equation.

postulate Opposition to the measure has been immortalized in Einstein's phrase: "God does not play dice in the atom." He always defended the existence of a local element of reality that would describe deterministically the probability distributions that we observe experimentally. During the twentieth century numerous confirmations of MC against local realistic theories have happened.

I make it clear that MC not only correctly describes a small group of experiments. The MC allows for predictions for full-featured, angular distributions, energy, all kinds. Formally, provides endless predictions. No wonder that today we use the MC to our advantage: lasers, atomic clocks, nuclear magnetic resonance, superconducting condensate, semiconductors and so on.

The MC is one of the finest intellectual constructs of humanity.
