The Birth Story of Matrix Intuition Website
I am a mathematics enthusiast with a master's degree in computer science, and I have been engaged in the development of deep learning, reinforcement learning, large models, and other fields for over ten years.
In recent years, I have worked on math exam preparation apps and math exam tutoring agents in my spare time. Eventually, I decided to build a website about matrices, accompanied by a crash course for quickly getting started with linear algebra — Learn Linear Algebra in Three Days.
While working on deep reinforcement learning projects, I deepened my understanding of stochastic processes and Markov chains. While working on large model projects, the technique of low-rank decomposition reminded me of how difficult it had been for me to learn linear algebra in the past. Combining that with my work experience, I decided to build a website — Matrix Intuition. That is the birth story of the Matrix Intuition website.
The core purpose of Matrix Intuition is not self-expression, but to help people solve a pain point: linear algebra is hard — how can one get started easily and quickly?
Before large models existed, although I had good ideas, it was difficult to express them with beautiful images, so this ideal was long delayed. Now, with the help of large models, many exquisite images have been successfully realized. They can transform abstract concepts and obscure computations in linear algebra into accessible intuitions, thereby helping more people learn linear algebra well.
Learn Linear Algebra in Three Days Is by No Means a Gimmick
Many people's first reaction upon seeing the title Learn Linear Algebra in Three Days is "misleading title" or "marketing gimmick." Such skepticism is understandable, but in mathematics, it is hard to fake things — right is right, wrong is wrong, and readers can verify it as soon as they open the book. I wrote this book entirely by hand from beginning to end and revised it repeatedly. My goal is clear: to enable everyone to learn linear algebra in three days.
The knowledge of linear algebra is both abstract and fragmented. To achieve this goal, I thought hard for a long time. Then inspiration struck: starting from the "vector," many seemingly isolated pieces of content can be connected. Only then did I find a route for quickly learning linear algebra.
Archimedes once said, "Give me a fulcrum, and I shall move the world." I also propose a fast learning path: use the definition of a vector as the fulcrum to leverage the whole of linear algebra. I truly believe that by carefully reading through the content of the book, learning linear algebra in three days is achievable.
Of course, everyone understands things from different angles and gains different things. But I am willing to devote my time and personally guide readers to help everyone achieve the goal of learning linear algebra in three days.
Finally, as a mathematics enthusiast and AI developer, I am very happy to meet more new friends. Everyone is welcome to discuss linear algebra questions with me.
