MIT18.06: Linear Algebra


  • Offered by: MIT
  • Prerequisites: English
  • Programming languages: None
  • Difficulty: 🌟🌟🌟
  • Class Hour: Varying from person to person

Gilbert Strang, a great mathematician at MIT, still insists on teaching in his eighties. His classic text book Introduction to Linear Algebra has been adopted as an official textbook by Tsinghua University. After reading the PDF version, I felt deeply guilty and spent more than 200 yuan to purchase a genuine version in English as collection. The cover of this book is attached below. If you can fully understand the mathematical meaning of the cover picture, then your understanding of linear algebra will definitely reach a new height.


In addition to the course materials, the famous Youtuber 3Blue1Brown's video series The Essence of Linear Algebra are also great learning resources.

On May 15th, 2023, revered mathematics professor Gilbert Strang capped his 61-year career as a faculty member at MIT by delivering his final 18.06 Linear Algebra lecture before retiring at the age of 88. In addition to a brief review for the course final exam, the overflowing audience (both in person and on the live YouTube stream) heard recollections, appreciations, and congratulations from Prof. Strang’s colleagues and former students. A rousing standing ovation concluded this historic event.
