"You speak of an impossibility"; interrupted the King; "you must have seen a vision; for to detect the difference between a line and a point by the sense of sight is, as everybody knows, in the nature of things, impossible; but it can be detected by the sense of hearing, and by the same means my shape can be exactly ascertained".
The king of lineland to A. Square
From Flatland by A. Square (E.Abbott)
I can hear the brittle beetle and the muffled moth-wings beat
I have but to click and listen to the echoes that I make and
I hear the waters glisten on the surface of the lake
From a quote in a chapter by David N. Lee
The acoustics in the hall were dead to rights
but all wrong. Sound bounced off walls, shot up
rafters, fell like the thud of the dread velvet curtain.
A bat boomeranged pulsating streams
of sound. There is information in an echo:
what did it know and when did it know it.
To locate the range of prey, eyes and ears
conspire. Even a fetus will dodge an ultrasound
as it penetrates the blooming silence.
The city’s single blind man stands on a corner
clucking his tongue. Marco? Polo! Friend or foe?
The answer lies as ever in delay.
