A Quote by Pascual Jordan

Observations not only disturb what is to be measured, they produce it. — © Pascual Jordan
Observations not only disturb what is to be measured, they produce it.
When I write, I disturb. When I show a film, I disturb. When I exhibit my painting, I disturb, and I disturb if I don't. I have a knack for disturbing.
Science is composed of laws which were originally based on a small, carefully selected set of observations, often not very accurately measured originally; but the laws have later been found to apply over much wider ranges of observations and much more accurately than the original data justified.
Whenever you take a step forward, you are bound to disturb something. You disturb the air as you go forward, you disturb the dust, the ground. You trample upon things. When a whole society moves forward, this trampling is on a much bigger scale; and each thing that you disturb, each vested interest which you want to remove, stands as an obstacle.
It is fairer to tax people on what they extract from the economy, as roughly measured by their consumption, than to tax them on what they produce for the economy, as roughly measured by their income.
Science is a process for learning about nature in which competing ideas about how the world works are measured against observations.
Labor, being itself a commodity, is measured as such by the labor time needed to produce the labor-commodity. And what is needed to produce this labor-commodity? Just enough labor time to produce the objects indispensable to the constant maintenance of labor, that is, to keep the worker alive and in a condition to propagate his race. The natural price of labor is no other than the wage minimum.
Difficulties arise when reported observations seem to conflict with 'facts' that the majority of scientists accept as established and immutable. Scientists tend to reject conflicting observations.....Nevertheless, the history of science shows that new observations and theories can eventually prevail.
A woman is often measured by the things she cannot control. She is measured by the way her body curves or doesn't curve, by where she is flat or straight or round. She is measured by 36-24-36 and inches and ages and numbers, by all the outside things that don’t ever add up to who she is on the inside. And so if a woman is to be measured, let her be measured by the things she can control, by who she is and who she is trying to become. Because as every woman knows, measurements are only statistics... and STATISTICS LIE.
Some think love can be measured by the amount of butterflies in their tummy. Others think love can be measured in bunches of flowers, or by using the words 'for ever.' But love can only truly be measured by actions. It can be a small thing, such as peeling an orange for a person you love because you know they don't like doing it.
Of Cooking. This is an art of various forms, the object of which is to give ordinary observations the appearance and character of those of the highest degree of accuracy. One of its numerous processes is to make multitudes of observations, and out of these to select only those which agree, or very nearly agree. If a hundred observations are made, the cook must be very unhappy if he cannot pick out fifteen or twenty which will do for serving up.
A mind at liberty to reflect on its own observations, if it produce nothing useful to the world, seldom fails of entertainment to itself.
A theory is a good theory if it satisfies two requirements: it must accurately describe a large class of observations on the basis of a model that contains only a few arbitrary elements, and it must make definite predictions about the results of future observations.
I feel that my job, as an artist, is to disturb the peace. And to disturb it intellectually, linguistically, politically and literally.
I have a "Do Not Disturb" sign on my hotel door. It's time to go to "Don't Disturb". It's been "Do Not" for too long. We should embrace the contraction.
Physics tells us observations can't be predicted absolutely. Rather, there's a range of possible observations each with a different probability.
The first step is to measure whatever can easily be measured. This is OK as far as it goes. The second step is to disregard that which can't be easily measured or to give it an arbitrary quantitative value. This is artificial and misleading. The third step is to presume that what can't be measured easily really isn't important. This is blindness. The fourth step is to say that what can't be easily measured really doesn't exist. This is suicide.
