He says, I plead guilty, but your physics is useless at this length scale.
他说，我没有错，而是你的物理在这个尺度上没有用武之地。
-
Yes, I have. Freshman year, I was having a lot of trouble in my Physics class, and
是的。大一那年，我在物理课上遇到了很多难题，
-
The first thing I have to do is give you understanding of the physics of the gas discharge tube.
首先要做的就是让你们理解,气体放电管的物理学原理。
-
Another reason I wanted to point this out in terms of the polar coordinates that we're using, is I think they're actually flipped from what you're used to seeing in physics.
另一个我想指出,我们采用极坐标的原因是，我认为它们实际上是,从你们习惯于看到的物理学中出来的。

My name's John Belcher, I'm in the Department of Physics, MIT.

-
I'm going to start going into the physics proper.
现在我们开始正式走进物理世界
-
What about that case? Well, I think if we were doing a matter of physics, as it posed to--sort of psychology Psychologically we understand why, losing weight might make a real difference about how you feel about yourself.
这个案例该如何解释，我认为，如果我们在研究物理问题，或者，心理学问题,从心理学的角度我们明白原因，减肥可以让你,自己感觉非常不一样。
-
The opening chapters of Leviathan, which I have only assigned a few, but the opening chapters present a kind of political physics where human beings are reduced to body and the body is further reduced to so much matter and motion.
利维坦》的开头几章，我只给你们布置了一些，开头几章呈现出,一种政治性的物理学,人类被缩小到身体,而身体继续被缩小到,大量物质和运动。
-
Like, I'm studying Theoretical Physics at UCL in London, so yeah, doing that and
比如，我在伦敦大学学院学习理论物理，所以这是一个工作，同时，
-
And obviously physics and I would say statistics a lot,
当然还有物理，很多统计方面的，
-
Physics... physics block, I'm taking that.
物理学……物理学不能选了，我还学着呢。
-
At the end of the day, I wound up starting in Math and Physics at Harvard, finishing an Applied Math and Economics and doing business.
最后，我跑去哈佛学了数学和物理，念完了应用数学和经济，跑去经商了。
-
And fairly soon into the conversation I demonstrated some principle that you've probably learned in your physics class having to do with an object at rest remaining at rest unless acted upon by a force.
很快，在交谈中,我就展示了一些原理,可能你们在物理课上学过,要使静止的物体保持静止,必须有外力作用。
-
I can't explain this because classical physics doesn't work at atomic dimensions.
我不能解释这个,因为经典物理在不适用,就原子尺度而言。
-
You will have to have a little more math, a little more physics to do that, but I am going to talk about something that you are familiar with.
你还需要学习再多一点的数学，再多一点的物理，但我将说一些,你所熟知的事。
-
I can change everything overnight; it does happen. I put that in for a reason because sometimes some of you have not taken a physics course and you don't know how to do well in physics and slowly you catch on and by the time it's Final exam you crack the code; you know how to do well.
我能一夜之间扭转乾坤,确实有过这样的例子,我这样做是因为,有时你们中有人可能以前没上过物理课,不知道怎样学好物理,但慢慢地你赶了上来,到期末考试的时候,你忽然灵光一闪,考起试来得心应手
-
Secondly, the book, you can see, one of you had a book here, it's about 1,100 pages and when I learned physics it was, like, 300 pages.
第二点,教材,你们可以看到,这位同学手上就有一本,大概1100页,我当初学物理的时候,教材只有300页
-
I've been here in MIT for thirty years, and in the early nineties I taught the large freshmen physics course, and electromagnetism.
我麻省理工工作三十年了，在上世纪九十年代初,我就开始给大一新生上物理课，以及电磁学。
-
A third project I'd like to tell you about is in physics.
我要讲的第三个项目是物理学的。
-
Now, I'm fully aware that this is not the flashiest example in physics, but I'm not worried about that right now.
我很清楚,这个并不是物理学中最经典的例子,但是这并是我现在的担心
-
And he decided, well, I'm interested in modern physics.
他说，我的兴趣是现代物理。
-
And I'm no scientist and I'm no specialist in sort of empirical matters, and believe me, I'm no authority on quantum mechanics, our best theory of fundamental physics.
我不是科学家,也不是实证方面的专家,相信我,关于量子力学,我并没有发言权,那可是基础物理中最经典的理论
-
For those of you who are not from MIT, - all MIT students have to take two semesters of physics all undergraduate students. For most students this is the most rigorous exposure to physics they've ever had In the first semester of physics, they study what I think was the basic nonunion mechanics.
如果你们不是麻省理工的学生，要知道麻省理工的所有学生,所有本科生---都得学两个学期的物理,对大多数学生来说,这是他们接受的最严格的物理学习,第一个学期他们学一些,基础力学。
-
So, one thing they did, because it was so easy to measure kinetic energy of electrons, is plot the frequency of the light against the kinetic energy of the electron that's coming off here. And in your notes and on these slides here, just for your reference, I'm just pointing out what's going to be predicted from classical physics.
他们做的其中一件事,因为测量电子动能是很容易的，就是画出光的频率,和出射电子动能之间的关系,在讲义的这里，仅仅是,为了做个比较，我要指出，经典物理所给出的预测,这个不作为对你们的要求。
-
I don't know what your major is; I don't know what you are going to do later so I picked the topics that all of us in physics find fascinating.
我不知道你们的专业是什么,我也不知道你们今后从事什么工作,因此,我会选择一些,物理学界公认的有趣的内容
-
I don't know how much you've seen, but quite often the way you learned physics earlier on in high school is probably different from the way professional physicists think about it.
我不知道你们对物理有多少了解,但你们以前在高中所学的物理知识,和资深物理学家们的看法,常常是很不一样的
-
We don't always want to go and solve the Schrodinger equation, and in fact, once we start talking about molecules, I can imagine none of you, as much as you love math or physics, want to be trying to solve this Schrodinger equation in that case either. So, what Lewis structures allow us to do is over 90% of the time be correct in terms of figuring out what the electron configuration is.
我们并不想每次都去解薛定谔方程，而且实际上，一旦我们开始讨论分子，我可以想象,你们中没有一个人，不管你有多么热爱数学或物理，会想去解这种情况下的薛定谔方程,总之，路易斯结构能让我们,有超过，90%，的概率判断出正确的,电子排布。
