Section 1:
Zero does have a physical meaning, which is "no change", "stable", "no events". It is easily proven by everyday examples things as "I'm hungry, my stomach makes sounds, if I eat, it stops making sounds, therefore, nothing (of the sort of making sounds from stomach) happens, and my stomach is stable"* There was a strong belief that the summation of equal positive and negative charges should not be zero. Since zero has no physical meaning, and there must be another language to express about that.
In other words, zero is the ceasing of objects desiring other objects, forming a stable state that only changes when something new is introduced to the situation (or the formula, to be mathematical) and which disrupts the balance.
