We owe to Newton the principle of gravitation.

万有引力原理发现应归功于牛顿。

Freedom, gravity, ego, and electron are constructs.

自由， 万有引力， 自我中电子都是概念。

The Coulomb-force in a star is equal to 3.4 octillion times of universal gravitation (neglect the effect of electricity charge tending to the surface).

因为这个斥力也比万有引力大3400亿亿亿倍（忽略电肤效应）。
