Then she was able to capture the sharp difference between light and dark.

And what we predict as an energy difference between two levels, we know should correspond to the energy of light that's either emitted, if we're giving off a photon, or that's absorbed if we're going to take on a photon and jump from a lower to a higher energy level.

我们预测，两个能级之间的能量差，我们知道，它要么和发出的光有关,如果它发出光子的话，要么它吸收光子,从低能级跃迁到，更高能级上去。

And Einstein credited de Broglie, which is a fair statement of lifting a corner of the great veil, because really there was this fundamental misunderstanding about what the difference was between matter and light, and the reality is that they can both be like-particles and they can both show characteristics of waves.

并且爱因斯坦相信德布罗意，他做了一个公正的论述,揭开了一个伟大面纱的一角，因为关于物质和光,以前确实存在着,根本性的误解，真实情况是它们同时,具有粒子和波的特性。

Do you think I should neck or not? I shall not enter the kingdom of heaven anyway so I don't see what difference it makes.'" And then she writes back, Mary Brittle: "Dear Sabbath: Light necking is acceptable, but I think your real problem is one of adjustment to the modern world.

你认为我是该做还是不该做，我反正都上不了天堂了,因此，我认为做不做都无所谓，之后她给她回信了，玛丽-巴瑞特，亲爱的萨巴斯，你的做法是可接受的，但我认为,你真正的问题是无法融入现代社会。

And you have to ask yourself is the energy difference here, the delta E in the electronic states, how does that compare with the E of visible light?

所以我们会问,是由于能量的不同么，例如deltaE在电子能态的不同，那如何把E与可见光联系起来？
