A related view is that sleep emerged to preserve energy and keep you out of trouble at night.

相似地，睡眠是为了保存能量,还能让你晚上不去惹麻烦。

It's not related to energy or environmental law at all,

虽然那份工作和能源或环境法没有一点联系，

So we see that we do not eject electrons in the case of the laser pointer, even if we have this intensity, it is still not related to the energy of an individual photon, so we won't see an effect.

所以我们看到我们用激光笔,还是没有逐出电子，即使我们有这样的强度，它仍然与一个单个的光子能量无关,所以我们不会看到光电效应。

And I know energy is related to Cv through Cv dT etcetera.

我们可以计算,这两个过程中的能量差。

PROFESSOR: Good. So, it's going to be in 3, because that's the shortest energy difference we can have, 3 those 2 are inversely related, so it must be n equals 3.

教授：好，是3，因为它的能量差最小，红色的是我们能看到的，所以一定是n等于。

So, if we start instead with talking about the energy levels, we can relate these to frequency, because we already said that frequency is related to, or it's equal to the initial energy level here minus the final energy level there over Planck's constant to get us to frequency.

如果我们从讨论能级开始，我们可以联系到频率上,因为我们说过频率和能量相关,或者说等于初始能量,减去末态能量除以普朗克常数。

All right, now what we're going to learn next time and Bob Field is going to teach the lecture next time, is how heat and work are related, and how they're really the same thing, and how they're related through the first law, through energy conservation.

这节课就到这里,下节课将由Bob，Field讲授,我们将学习功与热量的关系，认识到它们在本质上的相同之处，并通过热力学第一定律，亦即能量守恒定律，把它们联系起来。
