The Way We Get By 我们走过的路
By boat is the only way to get here, which is how we arrived.
乘船是到达这里的唯一途径,我们就是这样来的。
I'm not sure, but one theory might be that we have a primal fear of seeing other people get ahead of us-and if we can find a way to justify that instinct, by calling unfair means, we'll do so.
我不太确信,但是有一种说法可能是对的- - -我们害怕被别人超越- - -如果能找到一个方式评价这个事实,比如称之为不公平的手段,那么我们就会如此去描述。
And, the way we can get it, so, it's called usually V, so, V here stands for velocity more than for vector. And, you just get it by taking the derivative of a position vector with respect to time.
根据它的原理,我们通常用v表示,这里的V更代表速率而不是矢量,你能通过,对一个关于时间的位置向量求导得到它。
