Gilbert Strang is perhaps the greatest educator alive today, on par with Edward Tufte and Malcolm Gladwell. His incredible video lectures have enabled millions to shed their fear of math, discover linear algebra, and pursue careers in machine learning and data science. I often wonder what makes universities keep teaching linear algebra and other math classes when they can just turn their students on to Dr. Gilbert Strang's video lectures.
