The vast force of inertia known as China was to be united with the huge bulk of Russia in a single mass which no amount of new force could henceforward deflect.

被称为中国的巨大惯性力量将与俄罗斯的绝大部分合并为一个整体，此后再多的新力量也无法将其偏转。

Naturally a student knew nothing about mechanical laws, but he took for granted that he could learn, and went to his books to ask. He found that the force of inertia had troubled wiser men than he.

学生自然对力学定律一窍不通，但他理所当然地认为他会学，就去他的书上请教。他发现惯性力困扰着比他更聪明的人。
