-My question regards:
(i) mathematics (it regards numbers, so about arithmetic); but it is for everyone: you do Not necessarily be a mathematician or physicist to be a scientist!
(ii) specificly a fuzzy set, where an 'ordinary set' (called a 'crisp set') appears as an 'explicate order' in Bohmian physics, simply: a special case/limiting case.
(iii) limitedness: this is a deeper philosophical/logical question: if it (number 0) is limited then it can never be identical to nothingness. (Please see whether my hypothetical deduction is correct).
-Thanks for your answers! Marc.
