We started talking about these on Wednesday, and what we're going to start with is considering specifically the wave functions for multi-electron atoms.
我们从周三开始讨论这些,而且我们将要以特别地考虑,多电子原子的波函数,为开始。
So, if we're trying to figure out the wavelength of a Matsuzaka fastball, we need to consider the velocity first, which is 42 miles per hour.
如果我们尝试计算一个,松阪发出快球的波长,我们首先需要考虑速度,每小时为42英里。
And if I'm already in this habit, let my software, let my computer do that thinking for me and bubble up to the top of my attention what I should address first.
如果我已经有这样的习惯,让我的软件,或者电脑为我考虑这些事情,自动的把这,些邮件放到的最醒目的地方---最上面。
That links to the Trans fat thing and you want -for health reasons it's probably good not to eat too many of those.
这和反式脂肪有关,为健康考虑最好少吃那些食物
Externality When I'm figuring out how much effort to contribute to this firm I don't take into account that other half of profits that goes to you.
外部性,当我计算要为公司付出多少时,我没考虑到利润的一半会归你所有
I'm thinking of finishing and calling it When Will You Finish Don Quixote?
他考虑过完成并称它为,《你什么时候完成堂吉诃德》
And so we should base morality, whether we're thinking about what to do in our own lives or whether as legislators or citizens, we're thinking about what the laws should be.
所以我们应以道德为基准,不管是在考虑个人行为时,还是作为立法者或普通公民,考虑如何立法时。
Time. Okay, pitch and time and pitch and duration, excellent, so those are the two dimensions of music and well, indeed we could even call them the axes of music because we tend to think of pitch on a vertical axis.
时间,音高和时间,或者是音高和时值,非常好,它们是音乐的两个维度,其实我们可以称呼它们为音乐的两轴,因为我们趋向于将音高放在竖轴上来考虑
Couldn't it still be the case that as long as we take into account the importance of getting the right kinds of pleasures, then really pleasure is what it's all about and all that it's about? No, I think that's still not right.
它还说得通吗?,当我们考虑,正确的快乐的重要性时,那才是真正的快乐,而且仅为快乐?,不,我认为那还是不对。
I want to consider a particle which has definite acceleration a, a constant one, but a is now a vector.
我想考虑一个加速度为 a 的质点,加速度恒定,但 a 是一个矢量
So, if we think about the second case here where we have c n minus, now we're talking about a molecule with a net charge of negative 1.
那么,如果我们考虑的是第二个例子,也就是氰离子,那么现在我们讨论的是一个净电荷量为负一的分子。
So let's do this considering, for example, what it would look like if we were to write out the electron configuration for oxygen where z is going to be equal to 8.
我们来做这个考虑,举例来说,如果我们写出,有效电荷量为8的氧的电子构型。
So if we think about what that delta energy is, we call that the ionization of the 2 s, that's different from saying second ionization energy.
因此如果我们考虑这个,Δ,E,是什么的话,我们可以称它为,2,s,电子的电离能,这与我们前面所说的第二电离能是不同的。
They're interesting biological reasons for that, but certainly it's relevant, and it's important of course for physicians to be aware of this when they're screening overweight people for Diabetes given that excess risk in the women.
这些生理因素很有趣,也很有意义,考虑到女性的患病风险更高,医生们在为超重人群检查糖尿病时,很有必要注意到女性的患病风险
Do I have two yes answers if you wanna check two conditions at once? You know, this might seem to be a bit of a new context for some of you but consider a typical website.
我能不能对两个条件同时判断,来看看它们是不是都为真?,这些概念可能对你们中一些人有点新颖,那么就考虑一个典型网站。
Like what the heck have we been spending our time for-- our time on with Bubble Sort and with Selection Sort and in fact there's plenty of other N squared sorts that we're not even gonna bother looking at.
真见鬼,我们竟然在-,冒泡排序和选择排序上花时间,而事实上,还有很多我们根本都不想考虑的,复杂度为N平方的排序方法。
We can use the Coulomb force law to explain this where we can describe the force as a function of r.
我们用库伦定律解释它,力作为距离r的函数,让我们考虑一下。
So, Lewis structures are really a model for a way to think about what the valence electron configuration is, and as I said, it's not based on quantum mechanics, it's something that Lewis observed far, far before quantum mechanics were discovered.
路易斯结构实际上是一个用来考虑价,电子排布的模型,而就像我说的,它并不以量子力学为基础,而是路易斯在以前发现的,在量子力学出现很早前。
r And what that is the probability of finding an electron in some shell where we define the thickness as d r, some distance, r, from the nucleus.
在某个位置为,厚度为dr的壳层内,找到原子,的概率,我们来考虑下我们这里所说的。
We can also do a similar thing, and I'll keep my distance from the board, but we can instead be holding x constant, for example, putting x to be equal to zero, and then all we're doing is considering the electric field as a function of t.
我们也可以做类似的事情,把x固定为一个常数,例如令x等于零,然后,考虑电场作为时间的函数,这种情况下,我们划掉。
