Plural of eccentric; people who behave in an unconventional way, or mechanical parts that rotate off-center to create specific motions.
From 'eccentric' (Greek 'exkentros'). The term applies both to unusual people and to engineering components designed to function off their axis.
You can be an eccentric person, but you can also be an eccentric wheel in a machine—it's a word that engineers and personality psychologists both claim!
