It is the initial conditions, equipment, procedures and methodologies, observations and theory that is 'a neutrino'.
This is, of course, "such stuff as dreams are made on".
However, once this whole is given a name it is somehow cut free of these defining realities, takes on an existence all it's own, and becomes 'a particle'.
Vis.:
Prospero:
Our revels now are ended. These our actors,
As I foretold you, were all spirits, and
Are melted into air, into thin air:
And like the baseless fabric of this vision,
The cloud-capp'd tow'rs, the gorgeous palaces,
The solemn temples, the great globe itself,
and yea, even neutrinos,
Yea, all which it inherit, shall dissolve,
And, like this insubstantial pageant faded,
Leave not a rack behind. We are such stuff
As dreams are made on; and our little life
Is rounded with a sleep.
see: Shakespeare, The Tempest Act 4, scene 1, 148–158
compare Einstein:
“Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.”
