从能量的角度来说，消极情绪可能产生自多个源头。

From an energetic standpoint, negative emotions can originate from several sources.

通常我们从能量的角度来，考虑就能更好的理解这点。

So it can often make a lot more sense if we think about things in terms of energy.

如果它是正的，那意味着从能量的角度说，混合是不利的。

If it's positive, that means energetically speaking, the mixture is unfavorable.

What Einstein then clarified for us was that we could also be talking about energies, and he described the relationship between frequency and energy that they're proportional, if you want to know the energy, you just multiply the frequency by Planck's constant.

爱因斯坦阐述的是我们,也可以从能量的角度来谈论，他描述频率和能量之间的关系,是成比例的，如果希望知道能量值，你用普朗克常数乘以频率就可以了。

And if we talk about electrons or photoelectrons, again we can describe it in terms of energy, we can talk about velocity, and from there, of course, you can figure out the energy from 1/2 m v squared, and actually we can also describe the electron in terms of wavelength.

如果我们谈论电子或者光电子，我们又可以从能量的角度来描述它，我们可讨论速率，从那里，当然，你可以计算1/2，m，v2得出能量值，而且事实上我们也可以,从波长的角度来描述电子。
