Famous quotes containing the words length and/or units:
“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)
“Even in harmonious families there is this double life: the group life, which is the one we can observe in our neighbours household, and, underneath, anothersecret and passionate and intensewhich is the real life that stamps the faces and gives character to the voices of our friends. Always in his mind each member of these social units is escaping, running away, trying to break the net which circumstances and his own affections have woven about him.”
—Willa Cather (18731947)
