Yup. So it's just that ionization energy 94×10-18J that we have experimentally measured, 3 . 9 4 times 10 to the negative 18 joules.
它就是我们通过实验测得的,电离能3。,我们用所有的这些。

So that you do the experiment, you see the phenomenon, and then you see the visualization that adds things to the phenomenon that you normally can't see that are there whether or not sealed.
因此我们通过做实验，观测到现象，然后看到直观化的过程,它会将你平时看不见的物质,添加到这个现象中,让你感觉它本来就在那儿。

This was a very--a single experiment done within the United States, but the idea is appealing, that people are connected to one another via chains of people.

Different Jews have different opinions about how that works and the past few centuries have been an interesting experiment with modernity and how Jew is gonna face that and react to it So that's sort of just a brief introduction to Orthodox Judaism.
不同的犹太人有着不同的看法,那是如何实现的，而且过去的几百年,就是对现代性一个很有趣的实验,也是对犹太人将如何,面对并且回应它,这只称得上是,对犹太教正统派的简单介绍。

What can actually happen is that if you're in an enormous laboratory, which is made up of an enormous object, then you will find that you can, in fact, attach it to the wall.
其实真实的情况就是,如果你在一个巨大的实验室里,这个实验室由巨大的物体组成,你就会发现能够,将它与墙相连
-
All right, Is there anyone who disagrees with Joe and who thinks that our experiment disproves Mill's test, shows that that's not an adequate way, that you can't distinguish higher pleasures within the utilitarian framework?
好，有没有人不同意乔,谁认为我们的实验推翻了穆勒的检验，说明它并不足以证明，在功利主义范畴内可以分辨出高级快乐？
-
The Born exponent is determined experimentally, and there are tables of that.
因为Born指数是由实验决定的，而且这里有它的数据表格。
-
So, you can imagine what happens as it gets deposited into your bones, which is not the ideal situation after a long day in the lab.
所以你可以想象,当它碰到你的骨头时候会如何，当你在实验室,呆了一整天后这样可不太好。
-
And remember again, the binding energy physically is the negative of the ionization energy, and that's actually how you can experimentally check to see if this is actually correct.
电离能的负值，那个事实上是可以,通过实验来验证，它是否是对的,并且它等于负的。
-
So we need an experiment that will enable us to measure this quantity.
因此需要设计实验,来测量它。
-
For those of you don't know what that is it's simply an instrument that counts radioactive particles in the air, and MIT now that you're at MIT, you'll all have a chance to see one first hand if you're ever in any of the labs, especially in the chemistry or bio labs.
不知道它是什么,它就是一个简单的,计算在空气中放射粒子数目的仪器,你们现在来了，如果你们在实验室里工作的话,尤其是化学和生物实验室，你们有很多机会亲手用到它。
-
And we have to start to look at other experiments to try to get at what is it about physical attractiveness ? that makes people want to pursue the relationship?
我们必须看看其他的实验,来揭开外表吸引力的真面纱,了解为什么它能促使男女双方继续交往？
-
And this is absolutely confirming that what is happening is what we would expect to happen, because we would expect the case of reality is that, in fact, some shielding is going on, but it's not going to be total shielding, but at the same time it's not going to be no shielding at all.
因为我们期望看到的真实情况是,事实上,一些屏蔽发生了,但它不是完全的屏蔽，但与此同时它也不是，一点屏蔽也没有,如果我们从实验中得到电离能是多少。
-
For example, one of the experiments we do is measure the magnetic field of current coil, and after we do the experiment, we all have a passive visualization that shows the same experimental set-up, except we add to that.
比如，我们做的一个实验就是,测量电线圈的磁场，在我们做完实验之后，我们都感受到了一个直观化的过程,它展现了同样的实验过程，只是那是我们加的。
-
I've got here lots of flyers given to me by the director of the laboratories which will tell you which lab is the right lab for you, and they're offered many times a week. Yes?
我这里有不少小手册,实验室负责人给我的,它能告诉你该去哪个实验室,实验室在一周中很多个时间段是开放的,你说
-
So you need first to take the liquid helium and cool it below 53 degrees Kelvin before you can do the Joule-Thomson to cool it even further to make liquid helium.
我们首先需要,把温度江都53k一下,然后利用焦耳-汤姆孙实验,来继续冷却它。
-
And what we did was he put two detection plates on either side of these cathode rays, and when he put a voltage difference between these two plates, he wanted to see if he could actually bend the rays and test if they're actually charged or not.
但没有实验证明这件事,这就是Thomson所做的，它在阴极射线旁边放两块探测板,他想通过看当他,在两板之间加上电压后,阴极射线是不是会。
-
Here we're talking about a hydrogen atom and that's what we'll focus on today. And it's incredibly precise and we're able to make the predictions and match them with experiment.
是一个氢原子，我们今天都主要讨论它,它非常准确，我们可以做出,预测与实验比较，此外。
-
So, I mentioned at the beginning, while he was working with this radium bromide that I was very relieved to see that it did not kill him to do these experiments.
我在最开始就说了，由于他工作时接触到了溴化镭,我非常欣慰的,看到它做这些实验。
-
We use a liquid helium. And so in order to make a liquid helium, you can't take helium at room temperature and do this, because if you did, you would just heat it up, because the room temperature is above the inversion temperature, so Joule-Thomson would heat up the helium.
为了得到液氦,不能再常温,做这个实验,否则就是加热氦气，因为室温高于它的转变温度,所以焦耳-汤姆孙，实验会加热氦气。
-
This study is very interesting because what it did was take nurses, a cohort of a hundred thousand nurses -my wife is actually--just happens to be one of the subjects in this study because she's a nurse.
这项研究很有趣,它将十万名护士作为实验对象,我的太太恰好也是其中一名实验对象,她也是一名护士
