Did you know, that the triple integral of the divergence of the force field F is equal to the surface integral of the force field F dotted with its normal vectors, which is itself a mathematical statement of the physical fact that, in the absence of the creation or destruction of matter, the density within a region of space can change only by having it flow into or away from the region through its boundary?
Vector calculus is fun and enjoyable for the whole family!
