A centrifuge is a rotating machine that separates substances of different densities by the use of centrifugal force. The word derives from the adjective centrifugal,which comes from the Latin elements centrum, meaning center, and fugere, meaning to flee. Subterfuge is a stratagem used to evade or conceal something. The word shares centrifuge‘s Latin root fugere—hence the words’ similarity in sound. Subter is Latin for secretly or beneath.
