Differential Geometry: A Geometric Introduction by David W. Henderson presents differential geometry through an intuitive, geometric approach to curves and surfaces in three-dimensional Euclidean space. Rather than beginning with abstract formalism, the book develops the subject from concrete geometric questions such as what it means for a curve to be “straight,” how geodesics behave on cylinders, cones, and spheres, and how curvature can be understood both extrinsically and intrinsically.
It introduces tangent directions, smooth curves, curvature, tangent spaces, metrics, directional derivatives, and geodesics, using numerous examples and problems to connect the visual geometry with the mathematical formalism. The book is particularly characterized by its emphasis on the distinction between properties that depend on how a surface is embedded in space and those that belong to the surface itself.
The later development focuses on the deeper relationship between metric, curvature, parallel transport, and topology. The treatment leads to intrinsic descriptions of Gaussian curvature and shows how apparently extrinsic measurements can encode intrinsic geometric information, culminating in fundamental results such as Gauss's Theorema Egregium and the Gauss–Bonnet theorem.
The text also explores surfaces of revolution, the hyperbolic plane, minimal and ruled surfaces, and local coordinate descriptions, providing a bridge from elementary geometry toward modern differential geometry. Overall, the book is designed as an accessible introduction in which geometric intuition, rigorous mathematics, examples, and problem solving develop together rather than treating formalism as the starting point.
