How to go from one reference point to the other with this property. This property, f which we're going to call f.
这两个参考点插值,得到不同温度时工作物质的特性,我们把这一特性记做。
I want to spend a little time suggesting and developing the way in which that defense could be undertaken.
下面我想花点时间,阐述一下这一观点。
What they also did around the year one thousand was to identify-- to label--these particular spots--spaces and lines.
在公元一千年左右,他们还制定了规范,来标记这每一个点,间和线
So the next little piece of code I've written here, just move down to it slightly.
好,我可能想做的一件事情是,这两个点是不是同一个点呢?,因此我在下面写的。
Just take a look: if this is 9, 5 divided by 9 is always going to be 0 point something, and if you thus have two integers and you're rounding down, which is what happens when you do integral math we're using this operator, I'm going to get zero times whatever.
稍微看一看:如果这是9,5除以9会得到,0点几,如果你用两个整型数,你舍去小数,这就是当你们,用整型数使用这个操作的所发生的事情,我将得到数值0乘以任何一个数字。
One last word of encouragement, I'll say it again, there's a lot of words in this chapter, there's a lot of concepts, focus on the things that I talked about in class not the details, the basic concepts.
最后再说点鼓励你们的话吧,这一章涉及到很多名词,有很多概念,需要关注的不是我讲的细节,而是基本概念
And you can see this expanding rings of activity of stimulating, Cause a pattern of activities that move forward from the back of the brain to the front of the brain, in a very regular pattern which we call a visual field map.
眼睛在前面,指向这个红点,大家看到,刺激活动不断扩大的环路,引起一个活动的模式,从大脑的后不向前部移动,这一模式十分规律,我们可以称其为视觉分布图。
This is a food, a common food that most people would recognize, and I'd just like to see if you could guess what it is from the list of ingredients, so take a moment to look at the list of ingredients and then I'll see if you can guess.
这是一种食品,一种大多数人都见过的普通食品,我想看看,大家能否通过配料表猜出这是什么食品吗,所以,花点时间来看看这张配料表,看看大家能不能猜出来
That's a choice, and that choice turns out to be very interesting and really important, because if you connect these two points together, you get a straight line that has to intercept the x-axis at some point.
在这一选择下,我们会发现一件非常有趣,而且极其重要的事,当你把这两点用直线连接起来,你会发现这条直线,将与x轴在某点相交。
And that's a wonderful thing to have because it gives you that modularity, that encapsulation that basically says, when I create a point, the only way I can get at the values, is by using one of the defined methods, in this case it could be Cartesian, Cartesian and get all the pieces of that.
这是很棒的一件事情,因为它让你有了,模块性以及封装性,这基本上也就是说,当我创建了一个点,我能够得到它的值的唯一的方式,就是用一个定义好的方法,在这个例子中也就是。
Yeah. Suppose I choose it right down there I guess 0. Well, the tangent there will not even have an x intercept. So I'm really going to be dead in the water.
好,如果我选猜想数为0,好吧,这个点的切线甚至和x轴都没交点,所以在这儿这一原则,真的不起作用了。
It's an example of a technology called a gene chip that allows you to, on each one of these spots there is DNA for example, that's specific for a particular gene in your genome, in the human genome for example.
这是一种叫做,基因芯片的技术,其上每个点可能代表着一种DNA,它是你基因组中一个特定的基因,亦或是人类基因组中的一个基因
