This is a set of notes on introductory linear algebra developed for undergraduate science students, with an emphasis on geometric intuition. The creation of the notes is simply stemmed from the author being absolutely void of leisure activities during the COVID-19 pandemic era, and the self-destructive cynicism of typical physicists.

The goal of the literature is to give a broad introduction to linear algebra without diving too much into mathematical proofs. For further introduction, please read About this note.

The notes are under continuous updates and renovations to meet the demands of students from increasingly varied backgrounds and fields, including but not limited to physics, biology, statistics and economics. All readers are most welcomed to contribute to the editing by emailing the author, or collaborators who introduced the notes to relevant teaching activities.
