Bell's Theorem 很久以来一直是我的催眠神器，各种版本的故事和解读看了好多遍，就是无法理解，直到看到这个视频：

这个视频中介绍了用多个偏振镜（polarizing filter）的实验，确定「隐变量」不存在，这一方式很直白的介绍了「贝尔不等式」所希望验证的现象属实，再进一步引出了「贝尔不等式」的逻辑解释，非常的直观，一气呵成
这是一个文字版本的解释：

最早的 Bell 发表的论文：

Wikipedia 上对于贝尔不等式的介绍：

闲着无聊去查了 Wikipedia 上 Bell test experiments 条目的创建者，发现 Caroline Thompson 的介绍：
I'm a full-time "independent mature student" who stumbled upon some facts about the experiments claimed as supporting "quantum entanglement" some ten years ago. I have since read a very considerable number of the original papers involved, including Alain Aspect's PhD thesis, and found other problems with the experimental evidence. When you check out the details of any individual experiment, you find that the possibility of local realist explanations, applying basically classical ideas, has never been ruled out.
I don't expect to change the world but I do feel that others should be able to find out the facts with rather less effort than me!
I started contributing to wikipedia in the summer of 2004, and created and/or modified existing pages to create a linked set related to Bell's theorem.
最后注意到了文末的这么一段：
It is with deep regret that we write to inform you that Caroline Thompson passed away on Wednesday 8th February 2006. She had bravely fought cancer for several years, until she finally succumbed. Despite her illness she continued to work tirelessly for what she believed in. We still hope to get her final paper "The Chaotic Ball" published posthumously and we will keep her website open for others to read.
