Measurements of this precision are cool. I’ve seen the hypothesis that precision is what made the creation of modernity:
> This corresponding concept of “tolerance” turns out to be equally important. The ancient world was certainly capable of creating complex machinery (see the Antikythera Mechanism above), and the early modern period was able to put together the scientific method and new ways of conceptualizing the universe. But it’s the Industrial Revolution that created — or was created by — this notion that machines could be made in parts that fit together so closely that they could be interchangeable. That’s what got our machine age going, which in turn enabled guns and cars and transistors and computers and every other thing.
