I have written three books:

1. The Material Point Method, Springer 2023

2. Mathematics for Engineers and Scientists, Springer 2024.

3. Toán Học Chân Phương.

In "Mathematics for engineers and scientists: Concepts, Applications, and History", I present a new way to learn mathematics. The best way to learn maths is to self study, with your own pace along with good books. During the last few years I have self studied mathematics from scratch up to university level, and the result is the book that I mentioned. The basic principle is now throw any maths concept to the face of the students, but to explain why mathematicians need to come up with a certain maths concept, and how they define such concept in a mathematical way. 

Whether you're a high school student or a college student, if you want to learn maths in a less frustrating way, this book is for you. It provides guidelines or tips to learn maths, it tells you how to read maths books, how to do maths. It provides the historical context in which a math concept was developed, and it tells stories of mathematicians--the mathematicians who developed the maths that we're learning. It presents jokes about maths and mathematicians so that we can understand how mathematicians work and think.​​​ 

The book was written in the spirit that what one fool can do, another can. A guy in the early of his 40s with a job to take care of his family could learn maths, any student can and can do better.

I then translated this book to vietnamese and greatly expanded to more than 2000 pages and the result is the book Toán Học Chân Phương.
