the quiet miracle of many things agreeing to be one thing at once

means To make two or more things—clocks, devices, files, dancers—match up and operate in perfect time with each other.

from A 20th-century clipping of "synchronize," which traces back through Latin to the Greek "synkhronos," meaning "happening at the same time"—from "syn-" (together) and "khronos" (time). The short form "sync" rose with the machine age, when film, sound, and eventually data all needed to agree on the same heartbeat.

heart cells
