<\/div>

Is the concept of preparation unimportant in classical physics? Why do we never speak of a preparation there?<\/p>\n

The answer to this question probably lies in the fact that preparation is regarded as completely self-evident. In every experiment, controlled initial conditions are established at the outset. This is no different for the throwing experiment considered here than for an experiment in optics (producing a well-defined beam of light with apertures and filters) or in thermodynamics (setting temperature and pressure).<\/p>\n

In quantum mechanics one cannot be so sure of this. On the contrary: it will turn out that one of the central statements of quantum mechanics, the Heisenberg uncertainty relation, can be formulated as a statement about preparations: the simultaneous preparation of position and momentum of an ensemble of quantum objects is not possible.<\/p>\n

Much of what makes quantum mechanics so difficult to understand can be traced back to conceptual ambiguity. The concept of preparation helps to reduce this ambiguity a little.
