“Observers are men, animals, or machines able to learn about their environment and impelled to reduce their uncertainty about the events which occur in it, by dint of learning… [We] shall examine human observers who, because we have an inside understanding of their observational process, belong to a special category. For the moment, we shall not bother with HOW an observer learns, but will concentrate upon WHAT he learns about, i. e. what becomes more certain.”

“He will learn to observe carefully, and not to be deceived, as we sometimes are, by appearances.”

George Long (1800–1879) English classical scholar

An Old Man's Thoughts on Many Things, Of Education I
Context: Could not a boy be taught the elements of astronomy at the sole cost of using his eyes and his brain; taught slowly, certainly, and not wearied with too much at once? Some would learn more than others; but all would learn something. This is real science, real knowledge, which will make a boy wiser, and probably better too. He will learn to observe carefully, and not to be deceived, as we sometimes are, by appearances.

“In quantum physics, however, each observation implies an intervention in the observed. Because of the quantum physical laws of nature, a change of state of the observed is inevitably coupled to the observation process. So it's not a situation independent from the experiment that is observed, but we ourselves call forth the facts (or compel them to go in a certain direction to a disambiguation), that then become an observation.”

Pascual Jordan (1902–1980) German physicist and politician

In der Quantenphysik dagegen bedeutet jede Beobachtung einen Eingriff in das Beobachtete; eine Zustandsveränderung am Beobachteten ist auf Grund der quantenphysikalischen Naturgesetze mit dem Beobachtungsprozess zwangslaüfig verknüpft. Also nicht ein sowieso, unabhängig von diesem Experiment vorhandener Tatbestand wird wahrgenommen, sondern wir selber rufen die Tatbestände hervor (oder: nötigen sie in bestimmter Richtung zu einer Klärung), die dann zur Wahrnehmung gelangen.
Quantenmechanische Bemerkungen zur Biologie und Psychologie, Erkenntnis, Vol. 4 (1934). p. 228.
