Immersive Linear Algebra Book with Interactive Figures (2015)
Points and comments are a snapshot, not live.
An interactive online book teaching linear algebra with embedded visual figures.
The site hosts a full linear algebra textbook covering vectors, dot product, vector product, Gaussian elimination, matrices, determinants, rank, linear mappings, and eigenvalues/eigenvectors. Each chapter includes interactive figures that readers can manipulate to build intuition. The book is freely accessible, with navigation through a table of contents linking directly to each chapter's content.
What commenters are saying
Commenters overwhelmingly praised the book's clarity and interactive design, with many wishing such resources had existed when they were students. Several called out the effective use of tooltips and clean navigation. A minor debate emerged: one commenter criticized these resources as oversimplified and lacking rigorous proofs, while others defended them as sufficient for programmers and applied users. Suggestions included extending the approach to statistics and robotics.
One commenter recommended a similar interactive geometry resource (Clark University's Euclid's Elements), and another noted that LLMs now make creating such illustrations faster, linking to a machine learning systems book as an example.
