Famous quotes containing the words ultraviolet and/or fixed:
“Like ultraviolet rays memory shows to each man in the book of life a script that invisibly and prophetically glosses the text.”

“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 (18821961)
