Frankly speaking, although every day we classify the things around us, it's not really that easy to verbalize all the classification standards we have in our minds!

没错，为了让自己的公式和牛顿的公式一致，因此爱因斯坦开始着手研究一个新的理论，而解答就是广义相对论，该理论预测了大质量的物体会扭曲周遭的空间，造成附近的物体朝它“坠落”，也就是说，爱因斯坦发现空间是"弧形"的，那也表示即便是光，也会受到重力牵引的影响。

That's right. In order to make his own theory fit with that of Newton's, Einstein began to research a new theory, and the answer to this was the theory of general relativity. This theory predicted that objects with large masses would distort the space surrounding them, making the objects nearby "fall" towards them. That is to say, Einstein discovered that space is curved, which means that even light is affected by gravity.

第一是，所谓的现代化，其实说穿了就是便利性。简便，迅速是现代人对周遭所有事物的诉求，于是大多数人便养成了同时多工的习惯，以及预期即刻效果的心态。

The first is that what you call modernization, when you really look at it, is just convenience. Simple, convenient and quick are the demands people make of the things around them these days, so the majority of people get into the habit of doing several things at the one time and approach things with the expectation of instant results.
