我们物理课上常谈及两车追赶问题:一车甲以匀速前进,一车乙在后以一定的加速度a开始追赶,我们知道,无论这个加速度a多小,只要时间够长,乙肯定可以追上甲。而我们投资理财中,复利正是这个加速度。俗语称,“钱一旦带上利息,则今天的比明天的更值钱。”这其中原委就是因为有复利的存在。 We often talk about physics class two cars to catch up with the issue: a car at a uniform speed, a car B at a certain acceleration after a start to catch up, we know, no matter how small a acceleration, as long as long enough, B certainly can Catch up with a. And we invest in financial management, compound interest is the acceleration. As the saying goes, “Once money is brought in, money is more valuable today than tomorrow.” "The whole story is because of the existence of compound interest.
