Measurement From A Practical Point of View
Measurement is viewed in different ways in the many interpretations of quantum mechanics; however, despite the considerable philosophical differences, they almost universally agree on the practical question of what results from a routine quantum-physics laboratory measurement. To describe this, a simple framework to use is the Copenhagen interpretation, and it will be implicitly used in this section; the utility of this approach has been verified countless times, and all other interpretations are necessarily constructed so as to give the same quantitative predictions as this in almost every case.

Famous quotes containing the words measurement, practical, point and/or view:
“That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.”
—John Dos Passos (1896–1970)
“And so we ask for peace for the gods of our fathers, for the gods of our native land. It is reasonable that whatever each of us worships is really to be considered one and the same. We gaze up at the same stars, the sky covers us all, the same universe compasses us. What does it matter what practical systems we adopt in our search for the truth. Not by one avenue only can we arrive at so tremendous a secret.”
—Quintus Aurelius Symmachus (A.D. c. 340–402)
“From the point of view of literature Mr. Kipling is a genius who drops his aspirates. From the point of view of life, he is a reporter who knows vulgarity better than any one has ever known it.”
—Oscar Wilde (1854–1900)
“One might feel that, at my age, I should look on life with more gravity. After all, I’ve been privileged to listen, firsthand, to some of the most profound thinkers of my day ... who were all beset by gloom over the condition the world had gotten into. Then why can’t I view it with anything but amusement?”
—Anita Loos (1894–1981)
