The discussion focuses on the application of the Divergence Theorem in a problem involving the vector field F = xi + yj + zk and the surface of a sphere defined by s = x^2 + y^2 + z^2. The divergence of F is calculated as 3, but the initial assumption to multiply this by the area of the sphere (4π) to find the answer is incorrect. Instead, the volume of the sphere should be used, which is calculated as 4/3π for a radius of 1. The correct final answer for the problem is 4π. Understanding the distinction between surface area and volume is crucial in applying the Divergence Theorem correctly.
