Context and question: where the uncertainty is given as the standard deviation of the measured value from its expected value. There are a number of other such pairs of physically measurable values which obey a similar rule. One example is time vs. energy. The either-or nature of uncertainty forces measurement attempts to choose between trade offs, and given that they are quanta, the trade offs often take the form of either-or (as in Fourier analysis), rather than the compromises and gray areas of time series analysis.
What example is given as another paired relationship of uncertainly related to standard deviation?
Answer: time vs. energy
Context and question: It has been pointed out that Khmer and Indonesian classical arts were concerned with depicting the life of the gods, but to the Southeast Asian mind the life of the gods was the life of the peoples themselves—joyous, earthy, yet divine. The Tai, coming late into Southeast Asia, brought with them some Chinese artistic traditions, but they soon shed them in favour of the Khmer and Mon traditions, and the only indications of their earlier contact with Chinese arts were in the style of their temples, especially the tapering roof, and in their lacquerware.
Who brought Chinese dance to Southeast Asia?
Answer: unanswerable
Context and question: Yale has a history of difficult and prolonged labor negotiations, often culminating in strikes. There have been at least eight strikes since 1968, and The New York Times wrote that Yale has a reputation as having the worst record of labor tension of any university in the U.S. Yale's unusually large endowment exacerbates the tension over wages. Moreover, Yale has been accused of failing to treat workers with respect. In a 2003 strike, however, the university claimed that more union employees were working than striking. Professor David Graeber was 'retired' after he came to the defense of a student who was involved in campus labor issues.
Why was Professor David Graeber hired during the strike?
Answer:
