PTE Re-tell Lecture 真实讲座练习题:贝尔定理

在PTE中,无论是Summarise Spoken Text 还是 Re-tell Lecture的考题大都是从真实的讲座或者演讲中截取的中间经常经常夹杂很多不同的环境音.很多同学都反映有时未必是听不懂,而是听不到. 鉴于此,墨尔本悉尼文波雅思PTE专门为大家总结了真实讲座的PTE练习音频,相比新闻音频来说,整体更加接近PTE考试的真题,内容方面,我们也会为大家提供考试中存在的近似题,最近我们会持续更新,敬请期待!

Bell’s inequality is a mathematical statement that is able to distinguish between two different views of reality. One view of the reality comes really from the work of Albert Einstein, where when he was studying features of quantum physics, strange features, which basically said that something you do over here could in some quantum mechanic way influence something over there instantaneously. Einstein said that can’t really be what’s going on. It must be that secretly whatever is happening here and there has already determined before you undertake a measurement over here, so what you do here doesn’t really affect what’s over there. They’ve already in place secretly, you may have not known that, but that’s how reality’s constructed. That view of reality versus the standard quantum view, where indeed you do something over here and in a quantum way, does affect something over there. That was the second view. Nobody knew how to distinguish these two views of reality until John Bell came along and he wrote down the mathematically statement that can be in principle tested, and years later, it was tested. And the outcome of that experiment that comes out of his inequality could distinguish between Einstein’s view of reality and quantum view of reality.
