 We use the method chosen by Galileo in his great book "Dialogues
Concerning Two New Sciences"[1]. Galileo is often refered to as the
founder of modern physics. The most farreaching of his achievements was his
counsel's speech for mathematical rationalism against Aristotle's
logicoverbal approach, and his insistence for combining mathematical
analysis with experimentation.
In the dialog SG=Sagredo,
SV=Salviati,
SP=Simplicio

 Salviatti refers here to "Event Enhanced Quantum
Theory" of reference [6]  paper apparently well know to
the participants of the dialog.
 ...event.
 Heisenberg proposed the word "event" to replace the word
"measurement", the latter word carrying a suggestion of
human involvement.

 Cf. an illuminating discussion of this point
in [15,16].

generally we would need two Hilbert spaces:
21#21 and 22#22 that can be different,
but for the present discussion we need not be pedantic, so we
will assume them to be identified.

 A mathematical theory of a counter that leads to an inhomogeneous
Poisson process, starting from formal postulates that
are different than ours was given almost fifty
years ago by Res Jost [21] .

 From this
time on the subscript 113#113 may refer to either the initial state, as
in 114#114 or to free evolution, as in 115#115, or to initial state
evolving under free evolution. In case of confusion the actual meaning
should be derived from the context.

 The case of Hermitian singular deltafunction perturbation was discussed
by many authors  see [23,24,25,26,27,28,29]
and references therein

 This is why our time observable
does not fall into the family analysed axiomatically by Kijowski [37].
