In physical terms, the divergence of a three-dimensional vector field is the extent to which the vector field flow behaves like a source or a sink at a given point. It is a local measure of its outgoingnessâthe extent to which there is more exiting an infinitesimal region of space than entering it.ore rigorously, the divergence of a vector field F at a point p is defined as the limit of the net flow of F across the smooth boundary of a three-dimensional region V divided by the volume of V as V shrinks to p. Formally,
Cub Scouting is part of the Scouting program of the Boy Scouts of America (BSA), available to boys from first through fifth grade, or 7 to 11Â½ years of age and their families. Its membership is the largest of the three BSA divisions (Cub Scouting, Boy Scouting, and Venturing).

This was part of a greater change in programme, including the introduction of Scout Network for 18- to 25-year-olds.
