The discussion focuses on expressing the curvature of a 2-dimensional surface, specifically a sphere, without utilizing radius of curvature or extrinsic descriptions. It highlights the distinction between intrinsic and extrinsic curvature, emphasizing that intrinsic curvature can be defined without reference to external dimensions. The conversation encourages further exploration of curvature concepts as outlined in the provided Wikipedia link.
