Did you know?

From about the 1400s to the 1600s, the Latin borrowing turbation was used to refer to a disturbance or perturbation - even though both disturbance and perturbation were already well-established words in the language. Years later, the word was revived in the International Scientific Vocabulary as the base for congeliturbation, "the churning or heaving of the soil by freezing and thawing," and bioturbation, referring to the activity of organisms disturbing the sediment.
