Fixed Focal Length

Famous quotes containing the words fixed and/or length:

“To find the length of an object, we have to perform certain
physical operations. The concept of length is therefore fixed when the operations by which length is measured are fixed: that is, the concept of length involves as much as and nothing more than the set of operations by which length is determined.”
—Percy W. Bridgman (1882–1961)

“A playwright ... is ... the litmus paper of the arts. He’s got to be, because if he isn’t working on the same wave length as the audience, no one would know what in hell he was talking about. He is a kind of psychic journalist, even when he’s great.”
—Arthur Miller (b. 1915)
