In our travels around the rural Philippines, we've seen many different types of lights, from electric lights and candles to battery-powered fluorescent bulbs.

当我们游览菲律宾的农村时，看见许多不同种类的灯，有电灯、蜡烛和用电池的光管。

I use different types of colored lights shining through the crystals, so the ice structures act like complex lenses to refract the light in different ways.

我利用不同颜色的光照射晶体，冰晶结构就像复杂的棱镜一样将光线折射到不同的方向。

Dr LeCun's artificial visual cortex, by contrast, lights on the appropriate filters automatically as it is taught to distinguish the different types of object.

相反，LeCun博士的人工视觉皮层由于受到训练要去分辨不同种类的对象，所以可以自动的连通合适的过滤器。

So that's the important take-away message from this slide. If we think about these different types of lights, microwave light, if it's absorbed by a molecule, is a sufficient amount of frequency and energy to get those molecules to rotate. That, of course, generates heat, so that's how your microwaves work.

重要的信息，如果我们看看,这些不同种类的光，微波,如果被分子吸收，它的频率和能量可以,使分子转动,这当然的，会产生热量,这就是你们微波炉的工作原理。
