"I think the Volt is the most technically-advanced machine,car, on the road right now, I just hope the public jumps on the bandwagon."

But when I think about the question, would I want to spend my life ? hooked up to an experience machine?
但当我想到这个问题,我是否愿意让一生,在体验机器上度过时?
And I want to stress this, we're going to come back to it later on in the term, so the way I'd like you to think about it for now, is that somewhere in the machine, there's a big space that contains all possible values.
我想要强调一点,我们在晚些时候,还会回头来讲这一点,因此现在,我需要你们形成这么一个观点,就是在计算机的某处,有一个包含了所有可能值的,很大的空间,好。
Authorities say they quickly killed two of the gunmen, but two others continued to fire machine guns in the extended battle in Pul-i-Alam, Witnesses say U.S.military helicopters were part of the response force, and one aircraft fired a rocket into a multi-story building which the insurgents had seized, used to launch their attack and had rigged with explosives.

Like how can you possibly figure that out with actually compelling a machine to do it for you and sure enough we chatted for a few moments, I kind of gently pointed out well it's kind of like problem 7 last year.
就好像去逼计算机为你做这件事,就能解决问题一样,我们确实谈过这个问题,我委婉地告诉他,这种情况与我们去年讲过问题7类似。
There might have been one Coke vending machine at my high school, if any, I don't even remember.
我高中可能有一台可乐自动售卖机,我记不太清楚了
Now, I already revealed that, when I was talking about the rat lever machine.
我已经揭示了那一点,在我谈及老鼠杠杆机器时。
But if I'm accelerating, the force exerted by the spring and therefore, the needle the weighing machine reads is m.
但是如果我在加速运动,那么弹簧的弹力,也就是称重机上指针的读数就是 m
And you might say, wait a minute, isn't that a string, and the answer's no, I didn't say it's a string by putting quotes around it And notice how the machine responds differently to it.
你会想,等等,这不是个字符串么?,答案是否定的,我没用引号包围它就意味着它不是字符串,请注意计算机对它给出了不同的反应。
Yeah, if my machine will come back up, there we go. So, I'm going to now go ahead and write a little piece of code, and I put it here and I hope you can actually see these better this time, let me uncomment that region.
让我们写出代码来吧,好,如果我的电脑能回来的话,好了,那么,我要去写一小块代码,我把它放在这里以期望大家这次,能看的更清楚点。
Suppose instead, I want a machine that can take a recipe, the description of a sequence of steps, take that as its input, and then that machine will now act like what is described in that recipe.
假设换成这个,我想要一台可以安装描述,一系列步骤的结果的方法的机器,把那个当做输入设备,然后那台机器可以像方法中,描述的那样运行了。
I said, hook me up to that machine and I'll enjoy myself.
我说,把我连接到机器上,我会很享受。
We are, as I said, early in the semester when I said I'm a physicalist, I believe that people are just machines, but we're not just any old machine.
我们是,就像我之前说我是物理主义者时,我相信人只是机器,但我们不是旧机器。
Which is, and we're going to do some examples of this, initially we just typed in expressions Python into the interpreter; that is,directly into Python And as I suggested last time, the interpreter is actually a program inside of the machine that is basically following the rules we're describing here to deduce the value and print it up.
也就是,我们将会对这一点讲解一些例子,一开始我们只是简单的把表达式输入,到解释器里面去,也就是直接传给,我上次跟大家讲过,解释器实际上是,机器内置的,按照我们描述的规则,来推算出结果值并把值显示出来的一个东西。
Although it would make me very, very sad to discover this, I suppose it's possible some of you have such bad lives that moving on to the experience machine would be a step up.
虽然我会很难过,我想你们中有些人一生不顺,连接上体验机器可能是个好转。
Last time, I invited you to think about life on the experience machine, where the scientists are busy stimulating your brain in such a way as to give you an exact replica, from the insides of what it would be like having identical experiences to the ones you would have if you were really doing-- well, whatever it is that's worth doing.
上节课,我要你们思考,体验机里的生活,科学家们用它刺激你的大脑,给你一份完美的体验复制品,从体验相同的经历,到体验在现实生活中-,值得做的事情。
So I'm going to call that chips implanted in the brain to control prosthetics, but I'm going to make it a little bit more general and call a brain-machine interface.
我要谈谈,能控制假肢的植入性脑芯片,我会简要的谈到,我们把它称为脑机接口
But there's an important thing going on here, if I in fact wanted to combine those into a string I should have told the machine to do that, and I can do that, by explicitly saying, take that, which is a number, then add it to that string.
但是这里有个很重要的事情,实际上想要把这些加到一个字符串里面去,我应该告诉计算机去做这个,我应该这么做,通过明确的输入,也就是把这个对象,一个数字,然后把它加到一个字符串里面去。
That's the question we're going to try and address. If we can do this, this is good, because first of all, it removes any questions about what machine I'm running on, it's talking about fundamentally, how hard is this problem, and the second thing is, it is going to do it specifically in terms of the input. Which is one of the things that I was worried about.
这是一个我们接下来要去,尝试和解决的问题,如果我们能做到的话会很不错,因为首先,它解决了结果可能和我,运行的计算机有关系的问题,因为这从根本了告诉了,我们这个问题的复杂度,第二件事情,就是这种方法可以依据输入的大小来计算,而这正是我最担心的地方。
