因此你们能拣出,一个问题的主要描述,并将其编成计算性的东西。
So that means we're going to need to figure out what is the energy per photon that's emitted by that UV light.
所以那意味着我们将需要,计算出从紫外光源发射出的,每个光子的能量。
Which means that g we can really calculate all the thermodynamics in terms of only g.
这意味着,我们能够利用,计算出所有的热力学量。
Change the independent variable, find the change in the function, take the ratio and that's the derivative.
改变自变量,算出函数的变量,计算比值,这就是求导
It's using its set of rules to deduce the value and print them back out.
计算器用自己的规则,去计算出结果来并返回。
The paradox then is how do you create such a fast computer with such slow stuff?
那么这里的悖论就是,你是如何用传输如此缓慢的材料,制造出反应如此迅速的计算机的
He estimates, for his purposes, and he shows you calculations of the efficient portfolio frontier.

You might think that what a computer, what a chess-playing computer does is just this: it calculates every possible branch, every possible game from here on out.
你可能认为,一台电脑,或一台下棋电脑所做的工作就是这样,计算出所有可能的下法,以及与之对应的各种可能的棋局
z So in our first case, our first extreme case, would be that the z effective that is felt by electron number 1, is going to be plus 1.
被1号电子感知到的有效的,是+1所以,我们所能做的是计算出,我们从这个。
So hopefully if some of you have your calculators with you, you can confirm the answer that I got, which is that the energy is 7.82 times 10 to the -19 joules.
所以如果你们带了计算器,希望你们也能确认一下,我们算出的答案,能量等于,7,82乘以10的-19次方焦耳。
So we should be able to calculate a z effective for any atom that we want to talk about, as long as we know what that ionization energy is.
我们应该可以计算出任何一个,我们想要谈论的原子的有效电荷量,只要我们知道电离能是多少。
It says that the forward rate, which you can compute from today's newspaper or from today's website--you can compute the forward rates for all future dates.
这些告诉我们,人们可以从今天的报纸,或网上的信息中计算出,未来任意时刻的远期利率
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。
So we can figure out the energy of each photon emitted by our UV lamp by saying e is equal to h c over wavelength.
所以我们可以计算出,每个从紫外光源射出的光子,也就是e等于h乘以c除以波长。
We can tabulate them. We can know them, and then when we have reactions that inter-convert different compounds, we can calculate the heat of reaction is just the difference between the heat of formation of the reactants, and the heat of formation of the products, right.
种化合物的生成热,可以把它们列成表,可以认知它们,而当我们要处理,在不同化合物间转变的反应时,我们只要计算反应物和,生成物的生成热之间的不同,就能计算出反应热。
What they did is, they looked at 12 months, they took the months with the most births in it, which happened to be June, and calculated the probability of 3 percent.
俄克拉荷马神枪手谬误,他们看了十二个月的人数,然后选择了出生人数最多的一个月?,正好是6月,然后计算出3%的概率。
They might say my sample period was off, ... but that's what the theory-- ... using my data for the sample period that I computed-- the expected returns and co-variances says one should do.
他们可能说我的采样周期是有问题的,不过我的结果都是靠理论-,我采用自己收集的数据计算出-,预期收益和协方差可以用来指导我们的投资行为。
But because in many cases we can reasonably either model or measure equations of state, collect data for a material for its temperature, pressure, volume relations, then in fact if we can relate all these quantities to those then in fact we really can calculate essentially all of the thermodynamics. For the material.
但是因为在很多情况下,我们能够合理的给出状态方程的模型,或者通过收集一个物质的,温度,压强和体积之间的关系,来测量其状态方程,所以实际上我们可以给出压强等物理量,和热力学势之间的关系,并计算出所有的热力学势,对于给定的物质。
Just like u, we'd like to be able to express it in a way that allows us to calculate what happens only from equation of state data.
就像内能u一样,我们希望能够利用状态方程的数据,计算出其表达式,这些表达式能方便我们说出即将发生的过程。
But if we could statistically control for every other variable, all I'd need to do is measure the distance from your door to everybody else's door on campus and I could chart out who's going to fall in love with whom on the Yale campus.
如果我们能精确地控制其他可变因素,那么只需要测测距离,你宿舍门到其他宿舍门的距离,我就能够计算出,校园里谁爱上了谁。
If we look at our last structure here where we have nitrogen the middle, we can also figure out all those formal charges, and in this case we have plus 1 on the nitrogen, we have minus 2 on the carbon, and then we end up with a 0 on the sulfur there.
如果我们来看看最后一个结构,在中间的原子是氮,我们同样可以计算出所有的形式电荷,而在这种情况下,氮为正一,碳为负二,而最后硫为零。
