量子理论的微观人择原理
Micro-Anthropic Principle for Quantum theory
摘要:
概率模型(由玻尔兹曼等工作者在贝叶斯等先驱者的基础上开发)通常被认为仅仅是确定性现实的近似,直到量子革命(在海森伯和狄拉克的领导下),确定性描述被降低到近似状态,而观察者的作用变得特别突出。伴随而来的问题,缺乏客观性,在原来的哥本哈根解释并没有得到满意的解决,在新的办法,这种开创性的埃弗雷特。这种解释的不足之处是由于没有考虑到问题的人择方面,这意味着观察者身份的{ \it先验}不确定性。主观性与客观性的必要调和在这里通过区分观察者与感知者的概念来实现,感知者与特定观察者的认同机会需要由适当的人存原理来规定。有人建议,这应该通过熵分析,根据该分析,相关的微人权重被认为是成比例的埃弗雷特型分支通道的相关数量的对数。
英文摘要:
Probabilistic models (developped by workers such as Boltzmann, on foundations due to pioneers such as Bayes) were commonly regarded merely as approximations to a deterministic reality before the roles were reversed by the quantum revolution (under the leadership of Heisenberg and Dirac) whereby it was the deterministic description that was reduced to the status of an approximation, while the role of the observer became particularly prominent. The concomitant problem of lack of objectivity in the original Copenhagen interpretation has not been satisfactorily resolved in newer approaches of the kind pioneered by Everett. The deficiency of such interpretations is attributable to failure to allow for the anthropic aspect of the problem, meaning {\it a priori} uncertainty about the identity of the observer. The required reconciliation of subjectivity with objectivity is achieved here by distinguishing the concept of an observer from that of a perceptor, whose chances of identification with a particular observer need to be prescribed by a suitable anthropic principle. It is proposed that this should be done by an entropy ansatz according to which the relevant micro-anthropic weighting is taken to be proportional to the logarithm of the relevant number of Everett type branch-channels.
