In fact, the overall consciousness is also an infinitesimal consciousness. In physics, those of us who can't sum directly will sum in an infinitesimal way, that is, integral. The total charge is the charge density multiplied by the unit length/area/volume, which is actually the infinitesimal charge density with the length/area/volume as the integral, and the integral here is the corresponding curve/surface/triple integral. In fact, this is a common method in physics. Do more questions and understand the formula.
