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)

“those far-fet helps be such
As do bewray a want of inward touch,
and sure at length stolen goods do come to light.
But if, both for your love and skill, your name
You seek to nurse at fullest breasts of Fame,
Stella behold, and then begin to indite.”
—Sir Philip Sidney (1554–1586)
