To donate:

We will be given: r(vector)=[1/(r^2)]r(hat) and draw the vector field and calculate the divergence.

Next video in this series can be seen at:

picture of field suggests it diverges from origin (where field is singular)
Resolution: field has no source other than its singularity at the origin

Oooh my gosh! All that work to get "0" ! 😮
