Because the program is constantly revising its strategies, in light of what's worked and what hasn't worked in the past.
因为程序会不断依据过去,有效无效经验修改其策略
-
I am making light of it and I think it's somewhat justified, because the evidence is just so scanty.
我很鄙视这个观点,我认为我是有道理的,因为证据实在太有限
-
The artists chose bamboo because it is light,strong and can survive all kinds of weather.

So, what we would expect is that there is a relationship between intensity in kinetic energy because it was understood that however intense the light was, if you had a more intense light, it was a higher energy light beam.
光强和能量之间,应该有一定的关系,因为在我们的理解中,不管光强是多少，光的强度越大,光束能量越高。
-
He says he is thankful to those who saw the light voted for him because,in his words, they "want a better and fairer Croatia" without lawlessness.

That's because it's here where the rigid polarities between light and dark and good and evil, all of these absolute oppositions, begin to collapse.
这是因为这里就是光与暗,善与恶之间严格的两极分化，及所有绝对的对比开始崩塌的地方。
-
He says the station is not a happy one. He says when he saw it, he was very scared because the station isn't light, it's very dark.

And we don't put the mass of the electrons because they are so light in comparison.
我们不能得到电子的质量,因为它们相较起来太轻了。
-
It's no use talking about the negative relationship between a red light and a green light and a yellow, white, or blue one because they all have the same value.
讲什么它是红灯，不是绿灯,不是黄灯白灯一点关系都没有,它们所代表的意义都一样。
-
this is perhaps the most interesting thing because it forces us to show the complexity, to see the complexity, of semiotic relationships: a red light, just to return to the Christian holiday, a red light on a Christmas tree.
现在我们讲到了一个耐人寻味论点,这个问题迫使我们要思考，符号系统之间复杂的联系：,当我们再圣诞节时看到红灯，圣诞树上的红灯。
-
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。
-
c We know it's very specific for light because in this equation is c, the speed of light. So any time you go to use this equation, if you're trying to use it for an electron, just ask yourself first, does an electron travel at the speed of light?
我们知道它只对光适用是因为在这个方程里有,光速，所以下次你们用这个方程前，如果你们要把它用到一个电子上，先问问你自己，电子的运动速度是光速吗？
-
So, one thing they did, because it was so easy to measure kinetic energy of electrons, is plot the frequency of the light against the kinetic energy of the electron that's coming off here. And in your notes and on these slides here, just for your reference, I'm just pointing out what's going to be predicted from classical physics.
他们做的其中一件事,因为测量电子动能是很容易的，就是画出光的频率,和出射电子动能之间的关系,在讲义的这里，仅仅是,为了做个比较，我要指出，经典物理所给出的预测,这个不作为对你们的要求。
-
It ought to mean "to go forward" with everything behind it, but needless to say her thoughts on the subject were never implemented because if one day red light means "stop" and the next day red light means "go," there might be a few problems.
它因该表示勇往直前，当然她的想法没有实现,因为如果红灯今天表示停,明天表示走，会天下大乱的。
-
We can plug this in further when we're talking about the visible part of the light spectrum, because we know that for n final equals 2, then that would mean we plug in 2 squared here, so what we get is 1 over 4.
当我们讨论可见光谱的时候,我们可以把这个代进去,因为我们知道n末是等于2的,这意味着我们可以。
-
And I use the term photon here, and that's because he also concluded that light must be made up of these energy packets, and each packet has that h, that Planck's constant's worth of energy in it, so that's why you have to multiply Planck's constant times the frequency.
我这里用光子这个词,是因为他还总结出光,必须由这些能量包组成，每个能量,包有这个h，普朗克常数代表,里面的能量，所以这就是为什么你们,要用普朗克常数乘以频率。
