Gereshes is a personal blog at gereshes.com about science and math. Since 2018, 7 different Hacker News readers have linked it 87 times, most often “What is the n-body problem?”. The last post was in 2022, but the archive is still widely read.
Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
HN readers link this blog for its posts on chaos and the double pendulum. One commenter cites the animation to show that stochastic systems can be deterministic, with tiny changes in initial conditions producing large differences.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Too many acronyms

What Hacker News says?
Stochastic does not mean undeteministc. It means that tiny perturbations to initial conditions lead to huge differences in time evolution. See this gif for example https://gereshes.com/2019/02/18/chaos-and-the-double-pendulu...
