What is the difference between curl and divergence? - Quora

WebIn vector calculus, divergence is a vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point.. As an example, consider air as it is heated or … WebJun 17, 2024 · Here's a video by Grant Sanderson (3Blue1Brown): notice how fluid particles seem to want to get inside the yellow circle, to converge there – the vector field has negative divergence there.

"WebHere are two simple but useful facts about divergence and curl. Theorem 16.5.1 ∇ ⋅ (∇ × F) = 0 . In words, this says that the divergence of the curl is zero. Theorem 16.5.2 ∇ × (∇f) = 0 . That is, the curl of a gradient is the zero vector. Recalling that gradients are conservative vector fields, this says that the curl of a ... " - Divergence and curl 3blue1brown
