In this chapter, we will take a trip around several hot-spots where Bohmian
mechanics and its capacity to describe the microscopic reality, even in the
absence of measurements, can be harnessed as computational tools, in order to
help in the prediction of phenomenologically accessible information (also
useful for the followers of the Copenhagen theory). As a first example, we will
see how a Stochastic Schr\"odinger Equation, when used to compute the reduced
density matrix of a non-Markovian open quantum system, necessarily seems to
employ the Bohmian concept of a conditional wavefunction. We will see that by
dressing these conditional wavefunctions with an interpretation, the Bohmian
theory can prove to be a useful tool to build general quantum frameworks, like
a high-frequency electron transport model. As a second example, we will
introduce how a Copenhagen "observable operator" can be derived from numerical
properties of the Bohmian trajectories, which within Bohmian mechanics, are
well-defined even for an "unmeasured" system. Most importantly in practice,
even if these numbers are given no ontological meaning, not only we will be
able to simulate (thus, predict and talk about) them, but we will see that they
can be operationally determined in a weak value experiment. Therefore, they
will be practical numbers to characterize a quantum system irrespective of the
followed quantum theory.Comment: 13 pages, 1 figure, to be published as a Chapter in the book "Physics
