    I took honors linear algebra in college, used linear algebra for differential equations, signals, machine learning, and robotics, used it for work, used it in my free time.

    I did not understand it until I watched this series.

    Video lectures can be so much more than a blackboard/whiteboard facsimile, and I hope to the gods that 3blue1brown makes more in-depth lecture series like this one, and I hope even more that other educators take this series as an example of what’s possible.

      Also recommended in this vein is “Linear Algebra Done Right”.

          I read some of this and I think I agree with the people who warned you should go through something like strang first.

          Gotta love 3blue1brown; all his videos are so eye-opening. Not much of a surprise that he’s been hired by Khan Academy!

              His other videos are excellent as well, he’s really quite good at this format.
