: If you struggle with the concept of the shape operator or covariant derivatives, read Oprea's sections on mechanics and soap films to ground the theory.
When searching for the "better" resource in differential geometry, Oprea’s text consistently outclasses older classics like those by do Carmo or Tu for specific types of learners. : If you struggle with the concept of

The popularity of the PDF version led to a surge in requests for an updated edition. John, always eager to improve, obliged once more. The third edition of "Differential Geometry and Its Applications" boasted new exercises, updated references, and a more streamlined presentation. The third edition of "Differential Geometry and Its
