Reading Notes
Linear Algebra Done Right is a fundamentals book. It is not tied to one programming language, framework, or toolchain, which is exactly why it remains useful.
Linear algebra sits under graphics, physics, numerical computing, optimization, machine learning, signal processing, and many forms of data analysis. A stronger model here improves work in many other areas.
Useful Ideas
Structure Comes First
The book emphasizes vector spaces and linear maps before rushing into computation. That helps make the subject feel less like matrix manipulation and more like a language for structure.
Abstraction Has Practical Value
The abstract view is not ornamental. It gives names to patterns that show up repeatedly in computation and physics.
Eigenvalues Are Not Isolated Tricks
Eigenvalues and eigenvectors become more meaningful when they are connected to transformations and invariant directions.
Why I Keep It Nearby
This is a long-term reference for rebuilding mathematical fluency. It supports graphics, simulation, scientific computing, and physics work.
