Second, a deep critical reconsideration (Ghirardi, Grassi, and Benatti 1995) has made evident how the concept of 'distance' that characterizes the Hilbert space is inappropriate in accounting for the similarity or difference between macroscopic situations.
In most situations, only macroscopic objects are relevant to our experience.
Of the 25 patients scheduled for upfront surgery, gross complete resection was achieved in 11 patients (44%), whereas 6 patients suffered from localized macroscopic residual disease (R2-situation) and in 6 patients no resection was possible at all.
To illustrate this crucial point we consider, first of all, the embarrassing situation of a macroscopic object in the superposition of two differently located position states.
To test their prediction, students are provided with the real-world macroscopic experimental outcome of the situation and are asked to decide if their prediction is correct.
An important aspect of scientific thinking is to explain the macroscopic outcome of a given situation by applying a model at a microscopic level.
They may be adequate for some situations at the macroscopic scale, but can be ambiguous for multiscale problems.
It is shown that due to the limitation in the size of the system, a phase transition which could occur in a macroscopic sample is inhibited and situations may be realized where a metastable phase may be formed in preference to the most stable phase.
It is possible that velocity variations caused by heterogeneities at the macroscopic scale are responsible for this situation.
