In addition to many lectures, we have the working groups pleased to do both experiments and to do problem-solving exercises.
我们不仅有讲座,还有不同的小组,他们将做实验,和解决问题的练习。
So let's actually let you try another example of solving a problem that has to do with one of the spectrums.
下面请大家来看一下另一个例子,这次是一个需要大家解决的关于光谱的问题。
So let me turn to a different approach to solving the question, answering the question,which one should we believe?
所以让我用另一个方法来解决这个问题,回答该相信哪一个理论的问题?
If you can figure out why fails on three letters instead of 12, you'll be more than half way to solving the problem.
如果你能明白为什么程序,在输入三个字母的单词的时候没法运行,你就已经解决了问题的一半了。
To some extent we can tell whether you're solving a moral dilemma versus something else.
在某种程度上,我们可以看出,你是否正在解决道德两难问题,而不是在解决别的问题
I think that book will give you all the basic principles you need in calculus of one variable, more variables, elementary complex numbers, maybe solving some problems with vectors and so on, which you're going to get into.
我想那本书会给你所需的所有基本知识,包括一元和多元微积分,简单的复数运算,可以解决一些与矢量有关的问题,而这正是你们将要学的
What q2 makes this equal to 0 and Katie's answer is solving out the algebra here is that q2 that solves this must be a - c over b.
2为何值时这个算式等于0呢,凯特回答其实就是算出这个的解,即,q2=/b
We looked at the wave functions, we know the other part of solving the Schrodinger equation is to solve for the binding energy of electrons to the nucleus, so let's take a look at those.
我们看过波函数,我们知道解,薛定谔方程的其他部分,就是解对于原子核的电子结合能,所以我们来看一看。
So, sometimes people get confused when they're solving problems and call the amplitude this distance all the way from the max to the min but it's only half of that because we're only going back to the average level.
解题的时候会弄错,把这个从,最大值到最小值的距离,叫做幅值,但实际上,只有它的一半,只是它和平均值的差距。
Because you'll have an appropriate level of confidence and competence in your ability to do computational problem solving.
因为你们在自己的能力范围内,拥有应对解决计算问题的,正当水平的自信心和竞争力。
You also need to bring a calculator, we'll be solving problems that involve calculations.
你还需要带一个计算器,因为我们会需要解一些涉及计算的题目。
That's certainly one way to do it, but for computers that's not necessarily the easiest way. So another way of solving it is to do something we already saw last time, which is basically, why not simply enumerate all possible examples and check them?
将一个等式代入另一个等式,这当然是一种办法,但是对电脑来说这绝对不是一件简单的事,所以解决这个问题的办法,正如我们上一次看过的,非常基本?
We want to capture this idea of problem solving.
我们想抓住解决问题的这个想法。
All right. So that's all I'm going to say today in terms of solving the energy part of the Schrodinger equation, so what we're really going to focus on is the other part of the Schrodinger equation, psi which is solving for psi.
好,今天关于薛定谔方程,能量部分的解,就讲这么多,我们今天真正要关注的,是另一部分,薛定谔方程,也就是解。
You won't have to solve it in this class, you can wait till you get to 18.03 to start solving these types of differential equations, and hopefully, you'll all want the pleasure of actually solving the Schrodinger equation at some point. So, just keep taking chemistry, 18 03 you'll already have had 18.03 by that point and you'll have the opportunity to do that.
你们不用在课堂上就解它,你们可以等到得到18,03之后,再开始解这些类型的微分方程,希望你们都想得到,实际解薛定谔方程的乐趣,所以,保持来上化学课,你们在那个点将会得到,你们有机会做到的。
So this is kind of a modern show and that is kind of a retro language and it's also as will be one of the takeaways of this course completely irrelevant to what problem you are solving, the fact that this engineer is using--proclaiming to use Visual Basic really is not a compelling part of the story.
这看起来很时髦,像是重新流行的语言,当然,该语言是我们学习这门课程,过程中附带着要学习的,这与解决什么问题无关,事实上,使用VB真的不是,这个故事出彩的地方。
psi So we're going to for psi, and before that, we're going to figure out that instead of n just that one quantum number n, we're going to have a few other quantum numbers that fall out of solving the Schrodinger equation for what psi is.
我们要讲到,但在这之前,我们已经知道了,主量子数,现在我们需要知道,其他一些,解psi的薛定谔方程,所需要的量子数。
