• You can take these big risks of time, and if at the end of the day there's nothing to detect, you still know how to build a detector.

    如果最后你什么都没测到,你至少知道了,怎么造一个探器,所以如果你们。

  • And, of course, all that's left is this positive pudding. So that's not going to do anything either. And what he found when he did this experiment, was that the count rate with still 132 000 counts per minute.

    剩下的是带正电的布丁,也不会产生什么影响,结果他实验上观测到,计数器得每分钟132000下,所以目前为止,他可以说实验。

  • 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,这是个非常可靠的试,今天试,明天再试;,明年再你死的那天再;,得出的你的智商都还是一样,但这是个有效试吗?

  • They carry a potential, that is, if you could - if you had a tiny, tiny electrical meter, you could one put one electrode on one side of the cell membrane, on the extracellular side and one on the intracellular side and measure, you would measure a potential difference; just like a battery you would measure a potential difference.

    它们带有电势,就是说,如果你能有一个足够小的电位计,可以把一个电极放在细胞膜一侧,假设放在细胞外的一侧,另一个电极放在细胞内侧并量,你能测到一个电势差,就像电池那样能测到电势差

  • 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。

  • 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,那么只需要距离,你宿舍门其他宿舍门的距离,我就能够计算出,校园里谁爱上了谁。
