The Mirage, the Green Flash, and Theological Optics

And about the fourth watch of the night
he cometh unto them walking upon the sea

St. Mark 7: 48

A mirage is nothing but an image produced when the atmosphere behaves as a giant lens. This profusely illustrated talk explores the appearance of a world filled with mirages, the distortions of which rival those seen in a carnival house of mirrors. Although mirages are simply explained, they have produced strange stories in the hands of those who confuse the appearance and behavior of these images with that of the original objects (which obey quite different rules).
