A 725-page version of the complete book by Nawazish Ali Shah is available for viewing/download with a subscription.
What makes Nawazish Ali’s teaching effective is his emphasis on the fact that the covariant derivative of the metric tensor is – a critical property used in general relativity. Chapter 7 dedicates several proofs to this property. What makes Nawazish Ali’s teaching effective is his
: Understanding symmetric and antisymmetric tensors is crucial for applications in mechanics and relativity. Eigenvalues and Eigenvectors
The transition from vectors to tensors is conceptually difficult. In previous chapters, students visualize arrows in space. In Chapter 7, that visualization often fades into a world of indices, subscripts, superscripts, and summation conventions (the Einstein Summation Convention). Eigenvalues and Eigenvectors The transition from vectors to
