There's a couple of really good things in this intro that I wanted to point out. 1. I appreciate the rigour that went into the math notation. I need to see equations to start to make sense of something. And if you're a beginner, this at least provides an intuition for starting to grok these visuals. 2. It's visually very clear, and structured clearly. Sounds trivial, but this kind of visual organization helps a lot to break down complex topics. 3. Intro -> Math theory -> Python breakdown. The best way to teach math. 4. No memes. I feel like there's a huge temptation in articles for beginners to litter the post with moving gifs and memes which are distracting and annoying.
