He said, first, let it go a little distance, take the distance over time, that gives you the velocity now.
他说,首先,让它运动一小段距离,距离除以时间,你就能得到现在的速度
I try to like distance myself, go take a walk around the dorm, talk to other people,
我试着让自己远离写作,绕着宿舍散散步,找其他人聊聊天,
Notice that these transport costs go up in the distance you have to travel and they go up pretty fast.
注意这些交通成本,随着距离而增长并且增长得很快
But, of course, we want to go all the way to distance, so we take the second derivative and we have this equation for force here.
当然我们最后想要的是距离,所以我们取二阶微,分就有这个式子。
Because of the physics of diffusion it doesn't go linearly with distance.
由于扩散现象的物理特性,它和距离不是线性相关的
and Maybe this will go a little bit of the distance towards answering it Human beings learn that they were able to do that, that they are free moral agents. They find that out.
这是真的,还有,It,is,true—,或者距找到答案还有一段路程,人们才知道他们能够这样做,他们是有自由道义的个体,他们发现了这点。
Now, instead of being the cost of traveling that distance to go and buy the product, what's it going to be?
不是走一定距离,去买产品的成本,它是什么呢
It varies with the square of distance so it goes - in order to go twice as far it takes four times as long.
速度是与距离的平方正相关的--,如果要扩散两倍的距离要多花四倍的时间
These released particles can now go on and infect neighboring cells, they can travel in the bloodstream to infect cells at a distance and the virus spreads throughout a multicellular host.
这些释放出的病毒颗粒,可以继续感染邻近的细胞,它们可以随着血流去感染远距离的细胞,于是病毒可以在多细胞宿主体内全面扩散
