I'm child of the Columbia Space Shuttle, and I need to know all the electronic gimmicks invented yesterday that are already primitive cousins to those developed today from eight to five P.M.in Japan.

Same way that I have multiplication or division as a primitive, functions are going to give me, or somebody else who wrote them for me as part of a library, a new primitive that I'm going to be able to use.
我在用乘法或者除法当做原语,这些函数,或者别人写程序库中的函数,将会给我返回一个,我能使用的新原语。
And the last piece of this, is as said, I have to make sure I know what my primitive elements are, in terms of operations.
最后,正如我们所说,我们要确定我们的基本元素是什么,以便于操作,我希望大家可以学习到。
The law of talion, which is essentially the principle that a person should be punished according to the injury they inflicted, it's been decried as a primitive, archaic reflex of the vengeance or vendetta principle.
复仇法,本质上讲述了人应该根据其所造成的伤害,接受处罚的原则,却遭到了谴责,人们认为它是,复仇或仇杀原则原始古老的反映。
I am going to put up the most primitive version.
首先说一下波尔模型最原始的版本。
There were previous examples of people trying to have a deep wing that would do things, but if you take me back to my primitive phalanx here about 600-650 they're not doing that stuff yet.
先前有例子,人们会在布阵时增加两翼的排数,如果再回到我这里的原始方阵,公元前六百到六百五十年的方阵,不会采取这种方式
The message I'm trying to get to here, because I'm running you right up against time, is I have to be careful about what's a primitive step.
我想说的事情是,因为我正在跟大家讲算法时间复杂度,我们需要注意一个基本步骤的定义,如果我可以假设。
In a high-level language, square root might simply be a primitive that you can use rather than you having to go over and code it.
一个高级的语言,平方根可能仅仅,只是你能使用的一个基本要素,而不是你需要去编译它。
Assuming I have a set of primitive instructions that I can describe everything on I want to know what can I build.
假设我有一系列,我可以描述,所有东西的初始指令,我想知道我能建立什么。
So we're to assume we can get to any piece of data, any instruction in constant time, and the second assumption we're going to make is that the basic primitive steps take constant time, same amount of time to compute. Again, not completely true, but it's a good model, so arithmetic operations, comparisons, things of that sort, we're all going to assume are basically in that in that particular model.
因此如果我们假设在恒定的时间内,我们可以取得任何一块数据,任何一种数据结构的话,我们要做的第二个假设就是,基本的原始操作计算花费的时间是恒定的,这个假设也不是完全正确的,但这个模型其实挺不错的,因此算法操作,比较,这一类的事情,我们在这个特定的模型中都假设是基本的,操作,花费的时间是恒定相同的。
In order to create any kinds of expressions, we're going to need values. Primitive data elements.
因此下一节课,Python的一些简单介绍,我们需要值或者基础的数据类型l来创建。
