Paul Liu's personal blog at hippomath.blogspot.com covers math and science. Since 2011, 3 different Hacker News readers have linked it 3 times. The last post was in 2012, but the archive is still widely read.
Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
Linked as an explanation of the mathematics behind a submission about uncoupled pendulums of increasing lengths swinging together, a pendulum-waves post by Paul Liu.
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.
Math. Physics. And a touch of arrogant self-reflection.
What Hacker News says?
Here's an exposition on the math: http://hippomath.blogspot.com/2011/06/pendulum-waves-mathema...
