On Tensors…
…is now available as an interactive, animated eBook on Apple Books. In this post, similar to that given on our LinkedIn page (Featured Section) , we give a short summary of this book. From Linear Algebra to Surface Curvature: The Mathematics of a Curvature Story. Starting from introductory Linear Algebra (matrices, vectors, and multiplications thereof) we develop the Kernel-Index or Tensor Notation as written about by J.A. Schouten in the book Ricci-Calculus. Concepts from Linear Algebra are motivated by way of Colors and Tensors are motivated as a means of Storage. The Linear Algebra and Tensor machinery converge with a treatment of the computation of Surface Curvature from both an intrinsic and extrinsic point of view. We conclude with both graphical and computational illustrations of Gauss’ Theorema Egregium.

So Many Questions
Have you ever tried to learn about the Tensors of Differential Geometry and run into the wall of Index Notation? Have you ever thought about Linear Algebra in terms of Color? Did you know that Linear Algebra and Tensors are related? Did you ever see a geometry book that dealt with Curvature and wished for more pictures? Have you ever seen all these topics addressed in One Interactive, Graphically Intensive, Yet Mathematically Complete Book?
It’s Finally Here! Read this book and change your life.

Coming Up Next
With a grounding in Tensors and Tensor Computations as discussed in the book On Tensors we begin to transition into differential geometric computations for (the many forms of) Derivatives. These results will involve an interesting amalgamation of tools and techniques. We will be happy to show how the output of computations from software like Maple (by MapleSoft) can be used as the input to software like Mathematica (by Wolfram Research) which can be used to illustrate geometric concepts like Parallel Transport, etc.
