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。
And also had blind evaluators-- people who didn't know which condition they were in, evaluate how they were walking.
还找来盲测员-,那些不了解情况的人,评估他们的走路。
And that's because it's easier to test small things than big things. And it's easier to debug small things than big things.
这是因为对小一点的对象,进行测试比对大一点的对象进行测,试要简单多了,调试也是如此。
So now we have this derivative, in terms of physical quantities, things that we can measure.
现在我们得到了这个导数,它可以用实验可测的与。
Gee, I wonder if I could come up with a set of transitions occurring inside atomic hydrogen Just right match that what Angstrom measured back in 1853.
嘿!我想知道我是否可以想出,发生在氢原子内的,一系列的跃迁,正好符合,阿姆斯特朗在1853年测得的东西。
That means we can also measure velocity slightly later and make the slightly later come as close to right now as we want.
那我们也可以测出稍微迟一点的速度,让那个速度接近我们前面测得的速度
They developed a score based on the results from these various studies on how carefully the subjects in these studies adhered to the Mediterranean Diet.
该研究将这些不同研究中的受测者,按其对地中海式饮食的遵循程度予以评分
They're not the menials and servants of capricious gods.
他们也不是变幻无测上帝的奴仆。
The first, which I just stated, is that the deflection of that negative particle was just far and away more extreme, much, much larger than that of the positive particle. The other assumption that he made here is that the charge on the two particles was equal.
为了这么做,他又做了更多的观察,首先,像我之前已经说了,测到的负电粒子,偏转要远远,大于正电粒子,另外一个他做了一个假设。
Now if you've gone to the doctor, often they'll measure your triaglyceride level as a measure of how healthy your liver is and how healthy your diet is.
现在如果你去看医生,他们通常会测你的甘油三酯水平,以此作为你的肝健康和饮食健康的指标
But to make the most basic policy choice, I never saw the president do it based on here what the poll say is the most popular thing to do.
但是要选择最基本的政策的时候,我从没看见布什总统会依赖民测,看,民意测验结果是这样的,这是最受欢迎的做法。
Yes, it's a wonderfully reliable test I'll test you today; I'll test you tomorrow; I'll test you next year; I'll test you the day you die; I'll get the same IQ score ? Is it a valid test?
是的,这是个非常可靠的测试,今天测试,明天再测试;,明年再测,到你死的那天再测;,得出的你的智商都还是一样,但这是个有效测试吗?
If I look at a homonuclear molecule such as molecular hydrogen, this is perfect sharing.
如果我用这个测量表测氢分子,完全平均共价的分子。
Notice that. It's a less than or equal to.
如果我先测测只有一个元素的情况呢?
We studied the Heisenberg's uncertainty principle.
我们学习过海森堡的测不准原理。
This is pretty good news and confirms what other studies had shown, but this is especially persuasive because it pools all those studies and draws from such a large number of subjects.
这是个好消息,并且证实了其它研究的研究结果,不过它最有说服力的地方在于,它汇总了其它所有研究且受测者数量之大
It wasn't the--in a place where they use the Mediterranean Diet or not -but it was how much did individuals actually follow the Mediterranean Diet and then they looked to see what impact that had on health.
这不是基于某地区是否处于地海式饮食区,而是基于受测个体本身,遵循地中海式饮食的程度进行分组,然后观测其对健康的影响作用
I first tested it on the square root of 4 and in one iteration it found 2.
我首先测了下求4的平方根4,它只迭代了一次并返回了2。
He came back, and with him he brought the Uncertainty Principle.
三周后他回来了,和他一起的还有测不准原理。
But if we could statistically control for every other variable, all I'd need to do is measure the distance from your door to everybody else's door on campus and I could chart out who's going to fall in love with whom on the Yale campus.
如果我们能精确地控制其他可变因素,那么只需要测测距离,你宿舍门到其他宿舍门的距离,我就能够计算出,校园里谁爱上了谁。
pV So there is an arbitrary set point that needs to be defined, right? Because what you actually measure in the lab are changes in enthalpy, just like what you measure when you look at energy change of some sort, you measure the change in energy, right.
焓也是一样,焓是U加,所以需要定义一个任意的设定值,对吧?因为实际上你在实验室里,测得的是焓的改变,就像你在研究某种能量变化时,所测量的那样,你测量的是能量的改变,对吧。
This pool, twelve very large studies, if you put all the number of subjects in those studies together, it would come up to a million and a half people.
这项研究汇总了十二个大型研究,如果把所有研究的受测者数量加起来,将有一百五十万之多
