PTE Re-tell Lecture 真实讲座练习题:量子力学改变现实

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!

The central lesson of quantum mechanics relative to our previous understanding in classical mechanics is that the way we describe reality needs to be changed. The older description of reality that comes down to us from Newton is tell me where all of the objects are, all the particles and tell me how they’re moving. And that is the very definition of reality from what you can determine how reality will change over time. Quantum mechanics says you have to give up that picture, however, comfortable and intuitive it might be. What you really need to describe is give me the probabilities for where the particles are. That’s it. Give me that data and then I can use the new equations of the quantum mechanics to determine how these probabilities will change over time, allow me to predict at any given moment the likelihood that particles are here or there, or another particle is there or there. That’s the new picture of the reality, probabilities that evolve over time.
