The Law of Gravitation was so-and-so, but what was Gravitation?

万有引力定律是这样的， 但万有引力是什么？

It is usual to say that the stone falls to the ground because of the law of gravitation.

通常说石头落到地上是因为万有引力定律。

The law of gravitation, for example, is a physical law, while the law of association is a psychological law.

例如，万有引力定律是物理定律， 而联想定律是心理定律。

Anyway, the point is that Newton's law of gravitation is just an approximation - good enough to get us to the moon, but not perfect. General relativity is better.

不管怎样，重点是牛顿的万有引力定律知识一个近似值—虽然足以让我们登上月球，但还不够完美。广义相对论更好。

Newton's three laws, the universal law of gravitation, the reflecting telescope to check his work, and optics, and all this crazy stuff in that two years that he had stopped learning.

牛顿三大定律，万有引力定律，用反射式望远镜来验证他的假设， 还有光学相关的，在他停止学习的那两年中， 做了所有这些看似疯狂的事。

The same applies to the law of causality, or, to descend to what is less general, to such principles as the law of gravitation.

这同样适用于因果律，或者，归结为不那么普遍的原理，例如万有引力定律。

The business of science is to find uniformities, such as the laws of motion and the law of gravitation, to which, so far as our experience extends, there are no exceptions.

科学的任务是找到统一性， 例如运动定律和万有引力定律， 就我们的经验而言， 没有例外。
