Biologists explore the effects of ambient light on plants; acoustics experts try to control ambient sound; and meteorologists study ambient pressure, air, or temperature. All this can make ambient seem like a technical term, but when it first saw light of day, that all-encompassing adjective was as likely to be used in poetry as in science. John Milton used it in Paradise Lost, and Alexander Pope wrote of a mountain "whose tow'ring summit ambient clouds conceal'd." Both poets and scientists who use ambient owe a debt to the Latin verb ambire, meaning "to go around," the grandparent of our English word.
