There's only one occasion where it helps to go to three dimensions because there are certain things you can do in 3D you cannot do in less than 3D.
只有一种情况下进入三维是有意义的,因为有些事情你能在三维空间内完成,但低于三维就做不到了
If you want to do the nightlife in San Francisco, you go there. That's the best.

You try to design actually I'm going to come back to that in a second. It's like you're trying to use a hash function that spread things out pretty evenly. But the places you store into in those lists may have to themselves have a small list in there, and when you go to check something, you may have to do a linear search through the elements in that list.
你尝试着去设计,实际上过会儿我会回头讲解这个问题,类似于你需要用一个哈希函数,非常平均的将物体分发出去,但是在列表中你数据,映射到的地方可能会有自己的一小段列表,当你回头查找数据的时候,你可能需要在那一小段列表中做线性查找。
"We are able to do these transplants locally. We have got the expertise in this country and the only thing that we needed to do is to publicize and tell them, 'Yes,you do not have to spend all the money and go outside there, leave the comfort of your country and the beloved ones to have the transplants outside there - we can do it here."

There are coffee machines and there are lounge sofas and everything else. There are computers, there are printers, so it's a good lounge, and I think if you go there one day a week to do your problem sets, or more often, that's a good meeting place,I recommend that.
那里还有咖啡机和舒适的大沙发,以及一些其它设施,比如电脑,打印机,真的是个很好的休息室,如果你每周去那里,花一天时间完成你的作业,或者多去几次,确实是个好地方,我强力推荐
How do you get there? You go to go here, here and these could be busy roads, and so parents don't want to do it because of safety reasons, so you see how--when the country used to be laid out in a grid, like say New York City still is today, then people walk to get to places.
那要怎么才能去呢,你得绕道这里,还有那里的繁忙路段,出于安全原因家长们不允许孩子们这么做,可以看到,规划为网格状道路的地区,比如依旧保留了传统规划的纽约,人们出行是靠步行
So instead you'd have to maybe if you start with wavelength, go over there, and then figure out velocity and do something more like kinetic energy equals 1/2 n b squared to get there.
这时你要先从波长开始,到这,然后算出速度,然后像动能等于1/2nb平方得到这。
