But when we're thinking about actual wave behavior of electrons, it's just important to keep in the back of our head that some areas have positive amplitude and some have negative.
电子的波动行为时,我们,要记住,某些地方是正的,某些地方是负的,当我们讲到。
I'm going to keep coming back to that idea, but I'm going to call it computational thinking.
我会尽量回到这个想法上来,不过我将继续把它叫做计算思维。
Notice the importance -and we'll come back to it-- of the word "dominant": "the dominant" in the thinking of the Russian formalists and the struggle for dominance among species in a habitat.
注意这个词的重要性,我们还会讲到,支配,这个词:,俄国形式主义者所说的支配,和物种间争夺栖息地的支配。
To start out I'm going to go back to the thinking about development a little bit, embryonic development, and show you a picture here.
作为这节课的开始,我先稍微回顾一下,一些关于发育过程的内容,先说胚胎发育,这里有张图
Am I thinking back there, "Well, it starts in C and that's got an E up there and it's got a G"?
我当时是不是在想,这曲子是C调开头的,是在这里升到E调然后到G调吗
Does it make sense to think we could do this in less than linear time? You know, it takes a little bit of thinking. What would it mean do I see a hand way at the back, yes please? Thank you.
你要稍微想一想,这意味着什么?,那儿是有人举手么?后面的,请你来回答吧,谢谢你,小伙子,你让我体会到我上课的价值。
Notice here that it's different than the binary search case. We're certainly dividing down, but the combination now actually takes some work. I'll have to actually figure out how to put them back together. And that's a general thing you want to keep in mind when you're thinking about designing a divide and conquer kind of algorithm.
一个分治的例子,注这里,与二分查找所不同的地方,我们肯定是分解了,但是合并的过程还是需要一些工作量的,我会详细说明怎样把它们合并在一起的,当你在考虑设计一个分治算法时,这是你要必须记住的最基本的东西。
