For them,I am determined to do everything I can to accelerate our progress so we are actually adding jobs again."

It literally halves the amount of time it takes to solve that problem but we can actually do better.
它能把解决问题时间的缩短一半,但其实我们能做的更好。
What we can actually do is we could solve out for the X and for the Y.
实际上我们能够解出X和Y的值
"But unlike a lot of more traditional education, where it is a lecture, everything that we do is experiential, so we put young people into situations where they can actually be engaged in an activity; for example, starting their own mini-student experience those same challenges that we as adults would have when we start a business.

And, if we do so, we can actually get a handle on that Born exponent by solving the equation.
如果我们这样做,我们实际上能够得到波恩指数,通过解这个方程得到。
But it turns out though simple, though, some of these puzzle pieces actually are, we can actually start to do very interesting things very quickly.
虽然这些,拼图确实简单,但是我们可以很,迅速地利用它们。
You can bring any calculator you want, we don't actually have restrictions for calculator types here, but what you can't do, is you can't program any relevant chemical or information about constants in there.
你可以带你想用的任何一种计算器,我们并不限制计算器的类型,但是有一点是不允许的,那就是你不能使用编程的功能来记录,相关的化学常数或其它信息。
So you can actually say, how do I know which methods are associated with the class? For that, we can call dir. And what it does, is it gives me back a listing of all the things, dir all the methods, that are associated with it.
我们开始建立类了,我们得到了这些方法,因此实际上你可以说,我怎么知道,哪些方法是关联与这些类的?,为了解决这个问题,我们可以调用,这个方法的作用。
So what we can do then is for those schizophrenics that on typical neuleptics A we can actually switch them to the A typical neuleptics and run them under the same experiment again and look at what's happening.
我们接下来要做的是,对于那些服用典型药物的精神病患者,我们让他们转用药物,然后再对他们做相同的试验,来看看有什么变化。
Like how can you possibly figure that out with actually compelling a machine to do it for you and sure enough we chatted for a few moments, I kind of gently pointed out well it's kind of like problem 7 last year.
就好像去逼计算机为你做这件事,就能解决问题一样,我们确实谈过这个问题,我委婉地告诉他,这种情况与我们去年讲过问题7类似。
And so we can actually think about how do we calculate what the dissociation energy should be for h 2, so let's go ahead and do this.
因此,我们其实可以想到应该如何计算,氢分子的离解能,那么我们开始做一下吧。
All right. So we can switch back actually to our notes here -- oh, do we have--?
好的,所以我们可以转回到讲义,哦,我们,?
So this means we can actually calculate this for any molecule that we've drawn the Lewis structure for, because we actually do need to draw the Lewis structure before we know, for example, how many of each of these we have, or at least go through the rules.
这意味着我们可以将原来画过,路易斯结构的分子的形式电荷计算出来,因为我们其实在画出,路易斯结构之后才能知道,比如,这些量的值是多少,或者至少我们需要经过前面的那些步骤。
Once we can do that we can go on and say okay, what actually is a wave function, but first we need to know how to describe which ones were talking about.
我们就可以继续并说波函数到底是什么,但首先,我们需要知道,如何描述,我们说的,是哪一个波函数。
So, what we can do to actually get a probability instead of a probability density that we're talking about is to take the wave function squared, which we know is probability density, and multiply it by the volume of that very, very thin spherical shell that we're talking about at distance r.
我们能得到一个概率,而不是概率密度的方法,就是取波函数的平方,也就是概率密度,然后把它乘以一个在r处的,非常非常小的,壳层体积。
If we can sort things, you know, we get this n log n behavior, and we got a n log n behavior overall. But can we actually do better in terms of searching.
如果我们可以排序,如你所知,我们有n,log,n级别的算法,并且我有一个整体的n,log,n级别的算法,但是我们在搜索方面可以做的更好吗?
Actually, we can do it a little better than that, since we know the game is symmetric, we know that S1* is actually equal to S2*.
实际上我们能得出更多,因为我们知道这个博弈是对称的,我们知道S1*=S2
