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

We're going to really get into this next class, but I just want to introduce it to you to give us a start, and many of you have used Lewis structures in high school, but we'll be doing some much more challenging Lewis structures, I can assure you, in this class here.
其实我们下节课才会详细介绍它，但是今天我只想以简单介绍作为开始，大部分同学在高中就用过路易斯结构了，但是我们会遇到一些更具挑战性的,路易斯结构，我可以向大家保证，在这门课中会的。

So, if you were to lose half your brain, the other half can actually do a lot but some things are more prevalent and more powerful in one part of the brain than the other And I want to show you a brief film clip from "Scientific American" that illustrates the differences between the hemispheres, but before doing that,I want to provide some introductory facts.

What we've done is taken this pitch and played it all the way down an octave below it so we're actually getting back to this configuration of the pitch right next to it, and we could--then of course we could go down one more step and we would get the octave, which is a duplication of two-to-one.
我们所做的是固定一个音高，向下一路弹奏一个八度,所以事实上我们又回到了与这个固定音高相邻的音上，我们当然也可以向下再弹一组，然后得到这个八度，这其实就是两个八度对一个八度的重复。

OK? So you can see that, it's just walking through it, and in fact if I look at a couple of another-- another couple of examples, it's been a long day, again, you can see that property.

And now we're asking you to look at krypton, so the atomic mass is 36. You can actually just grab that handout the second handout on the exam and look at the periodic table there. So, which of the following ions listed is isoelectronic with krypton?
现在我们请大家来看一下氪原子，它的原子量是，36，大家其实可以拿出这张讲义,第二份关于考试的讲义,看一下上面的周期表，那么，下列离子中，哪一个是与氪原子是等电子的？
-
What this often--What this can be viewed as, as an extended version of selfish gene theory, which is that to the extent you're interconnected with other people you care about them more for purely selfish reasons.
其实我们可以把这个观点视为，自私基因理论的延伸，也就是说根据你和别人,互相联系的程度,你对他人的关心更多是因为自私的原因。

Well, you can use what's called an array which is kind of a list or a little satchel of that you might physically carry that you can put things in again and again, and with an array can you actually keep track of not just numbers but any kinds of things, other sprites or other pictures, or perhaps a little something like this.
你可以使用数组,它其实是个列表,或者说是个小包,你可以把东西一个个放到里面，通过数组你可以保存任何种类的变量,图片或者像，这个例子中的一些小变量，而不仅仅是数字。
-
So we're to assume we can get to any piece of data, any instruction in constant time, and the second assumption we're going to make is that the basic primitive steps take constant time, same amount of time to compute. Again, not completely true, but it's a good model, so arithmetic operations, comparisons, things of that sort, we're all going to assume are basically in that in that particular model.
因此如果我们假设在恒定的时间内,我们可以取得任何一块数据,任何一种数据结构的话,我们要做的第二个假设就是,基本的原始操作计算花费的时间是恒定的,这个假设也不是完全正确的，但这个模型其实挺不错的，因此算法操作，比较，这一类的事情，我们在这个特定的模型中都假设是基本的,操作，花费的时间是恒定相同的。
-
So we actually only need two electrons to fill up the valence shell of hydrogen, remember that's because all we need to fill up is the 1 s.
我们其实只需要两个电子,就可以将氢的价壳层排满，要记得这是因为我们只需要排满，1，s，轨道。
