I do think quantifying nothing is impossible because from my humble view re numbers even if taken from the simplest experiment are really infinite and the only way you could manage the numbers was by probability related to time and well a multitude of things...but I wondered does our rounding off the numbers to manager amounts hide something.
My point is can we really ever describe the quantum reality with maths.
I am really going to think about this.
Up side..although I don't do the math I am starting to understand a few things and how maths works.
This must do me good, I mean at my age 68 reading what I find demanding must help the old grey matter.
The mathematics allows us to define the probability of a particle existing in a particular state which is basically what Quantum Mechanics is about.
While Quantum Mechanics is counter-intuitive, the "reality" of the theory can be gauged by the technological advances made.

As Steven Weinberg the Nobel Prize Winner for his work in Electroweak theory once stated, if Quantum Mechanics suddenly "stopped working" our technology would be driven back into the late 19th century.
