Why HN links it
HN commenters link this blog's post about a dead fish swimming upstream in vortices when discussing fish locomotion, bird flight and the efficiency of natural movement. The comments only cite it and do not judge the writing.
Summarised by Claude from a sample of 6 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
Reminds me of the fascinating efficiency of fish, where even a dead fish can swim upstream, given the right kind of vortices. I wonder how much potential for improvement there still is for the human body. https://fyfluiddynamics.com/2018/07/when-i-was-a-child-my-fa...

HN discussionYeah, a dead mind can operate with the world like a dead fish[1] that swims up-stream. 1: https://fyfluiddynamics.com/2018/07/when-i-was-a-child-my-fa...

HN discussionEvolution is really very clever not just in the how our neurons control our bodies but also in how our physical forms make the motions we need to perform natural. As an extreme case, there's the famous video of a fish able to swim upstream despite being dead[1]. Working with robotic grasping professionally has made me acutely aware of how awesome my hands are and how much easier they make daily life compared to simp…

HN discussionIt reminds of that study recently that found dead troutcan still "swim" in water currents. Perhaps these birds have similarly incredible geometry that allow them to fly without exerting energy https://fyfluiddynamics.com/2018/07/when-i-was-a-child-my-fa...

HN discussionRead it dont know how new this is even though they coin a new term “flonon.” Karmen vortex shedding is the way I’ve heard it described and birds being highly sensitive to changes in pressure essentially ride the vortex sheds from the birds in front. Once the paper is tracked down I’m eager to see if there is something truly new! Fish do something even more incredible where they line the vortex sheds up where the add…
