Why “rattleback” is a great word
RATTLEBACK — [Noun] A semi-ellipsoidal spinning top that exhibits a preferred direction of rotation, rattling and reversing if spun in the opposite direction. From the English words 'rattle' (to make a rapid succession of short, sharp sounds) and 'back' (the rear surface of the human body or the opposite of forward), describing its motion of rattling and reversing direction. Unlike a common top, which spins with indifferent grace, or a gyroscope, which clings to its axis with inertial resolve, the rattleback is a creature of profound bias—a physical paradox of preferential motion. It is the soft, seismic shudder through a mahogany desk, the stuttering protest of a canted ellipse, and the sudden, decisive flip that defies a careless wrist—a small, obdurate lesson in how a system's deepest preference will violently reassert itself.
noun
