[This passage was excerpted from an
article published in 1979.]
Quantum mechanics is a highly
successful theory: it supplies methods
(5) for accurately calculating the results
of diverse experiments, especially with
minute particles. The predictions of
quantum mechanics, however, give only
the probability of an event, not a
(10) deterministic statement of whether or
not the event will occur. Because of
this probabilism, Einstein remained
strongly dissatisfied with the theory
throughout his life, though he did not
(15) maintain that quantum mechanics is
wrong. Rather, he held that it is
incomplete: in quantum mechanics the
motion of a particle must be described
in terms of probabilities, he argued,
(20) only because some parameters that
determine the motion have not been
specified. If these hypothetical
"hidden parameters" were known, a fully
deterministic trajectory could be
(25) defined. Significantly, this hiddenparameter
quantum theory leads to
experimental predictions different from
those of traditional quantum mechanics.
Einstein's ideas have been tested by
(30) experiments performed since his death,
and as most of these experiments support
traditional quantum mechanics,
Einstein's approach is almost certainly
erroneous.





27. The passage suggests that which of the following would have resulted if the experiments mentioned in lines 18-20 had not supported the predictions of traditional quantum mechanics?

(A) Einstein, had he been alive, would have revised his approach to quantum mechanics.
(B) Hidden-parameter theories would have been considered inaccurate descriptions of real-world phenomena.
(C) A deterministic description of the motion of a particle might still be considered possible.
(D) Quantum mechanics would have ceased to attract the attention of physicists.
(E) Einstein, had he been alive, would have abandoned attempts to specify the hidden parameters that describe motion.


答案是C,想问下A的问题是啥。

文章简要的意思就是经典的量子力学理论里有“不确定性”这一说,而这个不确定性让老爱一生都十分不爽,老爱认为:认为存在”隐藏参数“,只要研究清楚这些参数,什么鸟轨道就完全是确定的,哪还有什么不确定性,朗朗乾坤,物理世界,什么都应该是确定的,只要参数选的够多,就算把社会输进去,都能预测那天政变,哪天飞机爆炸,哪天哪里会发生强奸案,6月11号某考生的G会考多少。学界也把老爱的这理论叫“隐藏参数量子理论”。
后来老爱的理论促成了一些搞实验来预测轨道的,结果老爱死后这些实验结果反而证明“不确定性”是正确的,没什么丫的隐藏参数,幸好老爱死了,否则伤不起啊。

问题是如果实验结果没证明经典的量子力学是正确的 ,那么结果怎样?
不看答案也知道,那必然是老爱的理论就没人否定的了,也就是经典理论和老爱的理论没有定论,不能确定胜负。
A.如果,老爱,还活着,会修改他的理论。  既然没定论,凭什么?
B.“隐藏参数量子理论”会被认为是不精确的。 既然没定论,凭什么?
C.确定性论仍然被认为是可能的。   既然没定论,当然可能。正解。
D.经典论会不再吸引物理界注意力。  既然没定论,凭什么?
E.如果,老爱,还活着,会放弃其理论。 抽风了?

这就是老爱不会放弃的活生生的说明啊。
