When it comes to Bell's theorem, a cornerstone of modern quantum mechanics, there is one thing that everyone agrees on: it was published 50 years ago. Everything else is open to debate - especially its interpretation - and there is little prospect of these matters being settled soon. Indeed, Bell's theorem has become synonymous with the most puzzling meeting of metaphysics and physics that science has to offer. Nature prides itself on writing for the general reader, but explaining the idea published by Northern Irish physicist John Stewart Bell in 1964 poses a stiff challenge to that mantra of accessibility. But confused readers can be consoled by the fact that they are not alone: even the best quantum physicists are left bewildered by Bell's theorem. Still, to unlock the secrets of the Universe, a little effort seems worthwhile.

机译：贝尔定理是现代量子力学的基石，有一个大家都同意的事情：它是50年前出版的。其他所有问题都值得商debate，尤其是对它的解释，这些问题很快解决的可能性很小。确实，贝尔定理已成为科学所提供的最令人困惑的形而上学和物理学会议的代名词。自然界以为普通读者撰写文章而感到自豪，但是对北爱尔兰物理学家约翰·斯图尔特·贝尔（John Stewart Bell）于1964年发表的这一思想的解释对这一可及性的口号提出了严峻的挑战。但是迷惑的读者可能会因为他们并不孤单而感到困惑：即使是最优秀的量子物理学家也被贝尔定理所迷惑。不过，要解锁宇宙的秘密，似乎值得付出一些努力。
