We have 266 ping-pong balls, and we need someone, hopefully you, to be some radioactive material that are going to be emitting these ping-pong balls. And when the time comes, in just a minute, I'll ask the TAs to come down and hand these out very quickly to you, so we can do this experiment.
你们有些人那天,看到我在办公室数乒乓球,我们需要几个人,希望是你,来作为放射材料,放射这些乒乓球,等会我会让助教,把这些球发给你们。
And I can obviously do the other direction which is I can say skip to index 2 and all the remaining pieces. This lets me slice out, if you like, the front part or back part or a middle part of the tuple as I go along.

So my challenge to you, and I know Professor Guttag can do this, my challenge to you is, a year from now, come back and look at code you wrote here.
因此我这里有个具有挑战性的任务,我知道Guttag也可能会说这个任务,我的这个任务就是,一年以后,回头来看,你之前写过的代码。
So I guess I should go back, and let me do this correctly this way. Again, I can look at test, test and I guess test now if I want to get the element out-- angle bracket or square bracket?
但是这不是我想要的对不对?,我认为我该回到这里,让我改正这个错误,好,那么我还是对元组,那么现在我想从test中取出元素来?
Instead I'm going to be expecting the address of some int and the address of another int and thanks to this address I can literally find this address in RAM, do anything I want there, -- return and what I've just done is actually changed or mutate the values of those original variables.
我们所期望的是int型地址,和另外一个int型地址,幸亏这个地址,我可以找在RAM中找到它的地址,然后做我想做的事情,返回我处理后的东西,我可能改变了这些源变量。
Do this in your head and ask, "What can I possibly get?"
心算一下然后问问自己,"我能求出什么"
But instead in this chemistry course, I will just tell you the solutions to differential equations. And what we can do is we can start with some initial value of r, and here I write r being ten angstroms. That's a good approximation when we're talking about atoms because that's about the size of and atom.
但在这个课里,我会直接,告诉你们微分方程的解,我们可以给距离r一个初始值,我这里把r取10埃,当我们讨论原子时,这是一个很好的近似,因为原子的尺寸。
