It refuses to sit still, swinging back and forth as the universe's most reliable nervous tic.
means An oscillator is anything—a circuit, a pendulum, a vibrating crystal—that produces a steady, repeating back-and-forth motion or signal.
from From Latin 'oscillare,' to swing, which itself traces to 'oscillum'—a little face or mask of Bacchus that Roman farmers hung from trees to sway in the breeze over their vineyards. (The folk-etymology even imagines 'oscillum' as 'os-cillum,' a 'little mouth,' from 'os,' mouth.) Either way, the word swung into English through Latin, picking up the '-ator' suffix that turns a verb into the thing that does it—so an oscillator is, quite literally, a swinger.
