"That's not nothing"

[Marsellus Wallace]

That we say things possess "positive" and "negative" properties is not a real thing, in the sense that we could just as easily say that protons possess a negative electrical charge, while electrons possess a positive charge.

I know that Positive and negative are hypothetical principles taken in physics . But they are based on true facts; electron and proton are two opposite forces and neutron is a neutral force .
