What it is

Machine Thinking traces where mechanical precision comes from, from flat surface plates and the three-plate method up through lathes and early measuring tools. It is the first in a series on recreating the first micrometer.

Why Hacker News recommends it

HN commenters repeatedly recommend it as a half-hour mini-documentary on how precision is bootstrapped from scratch, relevant to machining and chip manufacturing threads.
