We know now with the same spring, by this comparison, we will find all objects now can be attributed a mass.
我们现在知道利用相同的弹簧,采用这种比较的方法,就会发现,所有物体都有确定的质量
Yes, that's probably true as a general observation, whether it comes through clearly on these two-- this comparison-- I'm not quite so sure, but there--I wouldn't say there's a great deal of detail in the first one.
是,可能从一般角度观察是对的,不管是否是通过,这两者的对比得出的结论,我也不太确定,但我不会说,第一首里有大量的细节处理

We did the comparison with the elephant or something; a is the second derivative of x and for this problem, when F is due to a spring, we know the force is that by studying the spring.
我们也已经把它与大象或其它东西作过比较,a 是 x 的二阶导数,在这个问题中,F 是由弹簧产生的,我们在讨论弹簧问题时已经知道了力的大小
Advance this pointer-- this finger, to the next element of the list which is 4, make the comparison.
前移这个指示器--也就是这根手指,让它指向列表中的,下一个元素4,再做比较。
