抄写得很好,就是没懂。
这段话就在同一行文中。
再仔细品味这几个字:“related” 和"it is often conflated”。

The observer becomes part of the observed system.
Thenotion of the observer becoming a part of the observed system isfundamentally new in physics. In quantum physics, the observer is nolonger external and neutral, but through the act of measurement hebecomes himself a part of observed reality. This marks the end of theneutrality of the experimenter. It also has huge implications on theepistemology of science: certain facts are no longer objectifiable inquantum theory. If in an exact science, such as physics, the outcome ofan experiment depends on the view of the observer, then what does thisimply for other fields of human knowledge? It would seem that in anyfaculty of science, there are different interpretations of the samephenomena. More often than occasionally, these interpretations are inconflict with each other. Does this mean that ultimate truth isunknowable?
The results of quantum theory, and particularlyof Heisenberg's work, left scientists puzzled. Many felt that quantumtheory had somehow "missed the point". At least Albert Einstein did so.He was an outspoken critic of quantum mechanics and is often quoted onhis comment regarding the Uncertainty Principle: "The Old One (God)doesn't play dice." He also said: "I like to believe that the moon isstill there even if we don't look at it." |
