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。
-
The first way is just to turn the crank on the math, and the second way is to do a little bit more imaginative about the process.
第一个方法就是纯数学推导,第二个方法我们将对,这个过程做一些物理图像的想象。

He eventually got a position at the University of Hamburg where he was a Professor of Physics.
泡利最终在汉堡大学,谋到了一个职位,他做的是大学的物理教授。
-
Some physical objects can do things of a far more interesting sort than other physical objects.
某些物理对象,可做的事远远比,其他物理对象能做的事有趣得多
-
It is true mathematically, you can add two numbers, but you've got to ask yourself,"What am I doing as a physicist when I add these two numbers?"
在数学上它是正确的,你可以引入这两个常数,但是你需要问问自己,当我引入这两个常数时,这么做有什么物理意义
-
That's what we're doing in physics.
这便是我们在物理上所做的。
-
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。
-
Certainly in principle we know how to calculate this and other stuff for a change in state of this sort, for lots of changes of state.
的确原则上我们可以对某个状态变化,计算这些物理量,或者其他物理量，对其他的变化也可以做相同的计算。
-
So now what we're going to do is start to extract what these things mean.
因此下一部要开始做的,就是从这些量里提取出它们的物理意义。
-
More generally speaking, we might say, they're subject to deterministic laws... that, as physical objects, it's true of them that they must do what the laws of physics and laws of nature require that they do.
我们甚至可以这样说,它们受制于决定性的法则,即,作为物理实体,它们必须按照,物理定律和自然法则的要求去做
-
You are not doing physics.
你就不是在做物理研究了
-
According to the physicalist view, a person is just a body that can do all of those things: can reflect, can be rational, can communicate, can make plans, can fall in love, can write poetry.
根据物理主义的观点,人是一个可以做以下事情的肉体,可以思考,可以理性,可以与人交流,可以制定计划,可以彼此相爱,可以写诗
-
And what the physicalist would need to do for each one of those-- For each one of those you can imagine a dualist who says, "We need to believe in a soul so as to explain seances.
对于这些东西,物理主义者该怎么做,对于这些,你可以想到二元论者会说,我们需要相信有灵魂才能解释通灵
-
These are physical knobs that are available us as experimentalists. And so when we turn these knobs on our system, we want to know how the enthalpy is changing for that system.
这些都是我们做实验可,以得到的物理变量,所以当我们在系统中,改变这些量的时候。
-
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
-
About 10 to 15 years later, another physicist, Ernest Rutherford, actually put this plum pudding model to test, Ernest Rutherford and he did it through studies that he'd been doing on radiation that was emitting something called alpha particles.
因此我们要，在上面再做改进,大概过了10到15年，另外一个物理学家,用实验来检测这个李子布丁模型,他一直从事alpha粒子辐射研究。
