But to worry, you do not need to believe me about exact predictions of exact disasters.

但是别担心，你不用相信我对某场灾难的精确预测。

It emphasized that at the quantum level, our world is intrinsically probabilistic, and exact predictions are fundamentally impossible.

它强调，在量子层面，我们的世界本质上是概率性的，准确的预测基本上是不可能的。

(Laughter) But to worry, you do not need to believe meabout exact predictions of exact disasters.

（笑声）但是担心的是，你不需要相信我对确切灾难的准确预测。

Second, any model that described the whole universe in detail would be much too complicated mathematically for us to be able to calculate exact predictions.

其次，任何详细描述整个宇宙的模型在数学上都过于复杂，以至于我们无法计算出准确的预测。

We don't always think mathematically, and we don't have crazy statistical models in our mind that allow us to come up with exact accurate predictions.

我们并不总是用数学的方式思考，我们的头脑中也没有疯狂的统计模型来让我们做出准确的预测。
