跑步是消耗多余能量的极好方法。

Running is an excellent way to burn off excess energy.

这也就是我们放出多余能量的原因。

So that's why we're giving off extra energy.

很久以前，第一次烹饪释放出来的多余能量直接进入我们的大脑。

The spare energy released by the first cooks, long ago, went straight to our heads.

What do you think the error is going to be by failing to recognize that at the end of 6 times 10 to the 23rd I have over-counted some energy?

你们可能会发现，这将会有误差,在6乘以10的23次方的末端,我多余地引入了一些能量？

we start high and go low, we're dealing with emission where we have excess energy that the electron's giving off, and that energy is going to be equal the energy of the photon that is released and, of course, through our equations we know how to get from energy to frequency or to wavelength of the photon.

当我们从高到低时，我们说的,是发射,电子有多余的能量给出，这个能量等于，发出,光子的能量，当然我们可以通过方程,从能量知道，光子的频率，和波长。
