Interactive linear algebra textbook with fully interactive figures. A handcrafted educational resource by academics (Ström, Åström, Akenine-Möller) covering vectors, matrices, eigenvalues, and fundamental linear algebra concepts. The first textbook to pair mathematical exposition with fully interactive visualizations.
A hub for learning through interactive, play-based exploration. Curated collection of explorable explanations and tools for creating them. Founded by Bret Victor's pioneering work.
