My feeling was just the opposite. I was constantly thinking "stop acting like I'm 12 and have 0 knowledge about linear algebra." As usual, it just depends what your context is, and the author will be happy to know there's an audience that finds it excellent.
- Moodles 6y agoI have a master's degree in math and a PhD in STEM so I know how linear algebra works. So when I say it's excellent writing, I don't mean perfectly calibrated for me or you. I mean it's excellent writing for a wide audience to get the gist of it. I think that's very difficult to do for math. An average 12 year old would not understand matrices without a very clear explanation. Having taught math to both children and undergrads, I think it's very easy to underestimate how easy it is once you already understand it. A sentence like: > for any ε > 0 and 0 < δ < 1, using poly(dimension, #nonzeros, condition, 1/ε, 1/δ) floating-point operations, our algorithm finds a solution having less than ε error with probability 1 - δ. Would confuse the shit out of most people. This video explains really beautifully what I mean: https://www.youtube.com/watch?v=M64HUIJFTZM https://www.youtube.com/watch?v=M64HUIJFTZM
