Essence of linear algebra preview
About this video
A five-minute preview of 3Blue1Brown's Essence of Linear Algebra series, which uses animation to build geometric intuition for topics from a standard linear algebra course.
Why it appears in the archive
HN repeatedly recommends the series as the best intuition-first, visual introduction to linear algebra and a benchmark for clear math explanation.

Wow, this lecturer is great! I think this is the most intuitive explanation of Kalman filters I've seen yet. I've seen other lecturers try to quickly jump into state space and lose students with big matrices. I would have paid good money for this if I wasn't already familiar with the material. The clarity is up there with The Essence of Linear Algebra: [VIDEO] Trading math videos on the Internet--definitely nerds.
Read original comment ↗Fror a high-level overview of linear algebra, 3Blue1Brown's youtube series I cannot recommend highly enough. [VIDEO]
Read original comment ↗For linear algebra basics, I also especially recommend 3Blue1Brown's youtube channel and his "Essence of" series: [VIDEO] I've never seen the material presented more clearly - it's completely visual and focused on building intuition first.
Read original comment ↗If anyone's looking for a (high level) overview of linear algebra, I'd highly recommend 3blue1brown's video series: [VIDEO] It's mostly graphical, and is really helpful in forming and cementing an intuition for linear algebra.
Read original comment ↗Two quick things I can recommend without hesitation, which focus on an intuitive understanding of concepts: 1. Essence of Linear Algebra mini-series - [VIDEO] 2. Better Explained website - [LINK] YouTube has a lot of high quality math content, it definitely helped through university. It's also worth mentioning the Stanford U courses. The main takeaway I have for you is learn the concepts intuitively first, then spend the time to play around with them on paper until they sink in. Some things will be easy, some will be frustrating, much like programming you will walk away from a frustrating problem and have an epiphany while doing something completely different. All the best and have fun!
Read original comment ↗It at least cuts down on the amount of time you have to explain the mechanics of it. This is more intuitive to memorize than an algorithm composed of bullet-point instructions. For intuition, I highly recommend [VIDEO] - I think both the intuition and practicing the details should be learned.
Read original comment ↗See the "Essence of Linear Algebra" (visualized) by the same author -- it should give you more intuition into the nature of the transformations: Essence of Linear Algebra [VIDEO]
Read original comment ↗Have you seen the Essence of Linear Algebra video series posted to HN a few days ago? Seeing the geometric transformations animated gives you intuition hard to develop otherwise: Essence of Linear Algebra (visualized) [VIDEO]
