Effective Focal Length

Famous quotes containing the words effective and/or length:

“I know no method to secure the repeal of bad or obnoxious laws so effective as their stringent execution.”

“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)
