Literal punishment: for example, in the Code of Hammurabi, where someone's ox kills a child, then the ox owner's child is killed.
例如,在汉穆拉比法典里,如果某人的牛,杀死了一个小孩,那么这头牛的主人的小孩也应处死。
If you look at cancer, for example which is down here, only 3.7% of deaths, much smaller then the number today.
比如癌症,你可以在这下面看到,只占了3.7%,比现在少多了
Now, the first application tends to not be quite as exciting as, for example, all the other organisms people have put it in since then you can have flies, you see transgenic mice that are glowing green with this GFP.
现在看来,第一个应用不像之后,其它放入一些生物一样激动人心,你可以用苍蝇,你可以看到发绿光的转基因老鼠。
And the question then is, " "What if a child was raised by a single parent, for example?"
问题是,“要是孩子成长于单亲家庭会怎样“
In contrast, if you look at a U.S.City, ten years ago in 1997 for example, then people still died but they didn't die predominantly from infectious diseases.
相反,我们看美国的城市,例如在十年前,即一九九七年,人们还是会死亡,但是最主要的死因不再是感染性疾病
But you know, you kind of wonder if that's a good example for fire insurance because if the whole city burns down, then insurance companies would go bankrupt anyway, right?
但是你也许会疑惑,对于阐述火险来说,这是不是个好例子,因为如果整个城市被烧毁,那么保险公司就会破产,对吧
For example, if t* is the time you hit the ground, then t* satisfies the equation h - 1/2 g ^2 = 0.
例如,如果在 t* 时刻落地,那 t* 就满足等式 h - 1/2 g ? ^2 = 0
So, for example, if you had chosen Beta and your pair had chosen Alpha, then you would get a C and your pair would get an A.
比如说你选了β而你的对手选了α,你会得到C而你的对手会得到A
So, these are receptors, for example, that bind the ligand and then liberate an enzyme which promotes some sort of reaction inside the cell, often it's kinases but doesn't have to be.
例如,这里是受体,与配体相结合,激活一种酶,这种酶能够催化细胞内的某些反应,这些酶通常都是激酶,但不全是
Then you look at-- to the right of the line with meat, for example, only 30% percent of people are eating the recommended amount of meat, the rest are eating too much.
然后你看到,比如,右边肉类一项,只有30%的人肉类摄入达标,剩下的全都吃得过量
Some of you might be saying in your heads, wait a second, I happen to know, I happen to remember from high school, p have different energies then, for example, s orbitals.
有些人,可能会心里想:,等等,我记得,高中的时候学过,轨道,that,p,orbitals,和s轨道,的能级是不同的。
So finally, if we talk about our last example of when n is going to be equal 2, l -1 and then minus 1 for m.
最后我们要讲的,这个例子,是n等于2时,等于1,we,can,have,2,,1,for,l,而m等于。
Because if it was a disease that was carried by both humans and squirrels, for example, then in order to get rid of it on the planet, you'd have to vaccinate not only all the people but all the squirrels, right?
因为假如人和松鼠都能携带,某种疾病的话,想要把这种疾病从地球上清除,不仅要给所有人接种疫苗,还要给所有松鼠接种疫苗
Maybe you don't control thermostats in your dorm room, some of you do and some of you don't probably, and maybe it doesn't work very well so it might not be a good example, but imagine a perfect thermostat that you set for a temperature and then the temperature stays the same inside the room no matter what the temperature is outside.
可能你根本就不理卧室里的恒温器,有些人去调它,有些人就置之不理,可能它压根就是坏的,所以这个例子也许并不恰当,但你还是想象一个完美运行的恒温器,你设定温度后房间里的温度就保持不变,不管外面温度是多少
So, for example, for boron, 2s2 now we're dealing with 1 s 2, then 2 s 2, and now we have to move into the p orbital 2p1 so we go to 2 p 1.
举例来说对于硼,现在我们知道有1s2然后,现在我们必须,移至p轨道即。
So for example, if you know how to draw an s orbital for a hydrogen atom, then you already know how to draw the shape of an s orbital or a p orbital for argon.
举个例子,如果你们知道如果画,氢原子的s轨道,那么你们已经知道如何去,画氩的s轨道和p轨道的形状。
If you cut and you open up a segment of DNA then you've left these sticky ends, for example and these sticky ends are capable of recognizing each other by the process of hybridization.
如果你进行切割打开一个DNA片段,就会留下,比如说,这些粘性末端,这些粘性末端能在杂交的过程中互相识别
So, for example, for sodium, we can instead write neon and then 3 s 1.
所以举例来说对于钠其他的外层电子,的结合的电子。
So, for example, we have this average level, and then it can go high where we have the peak, or it can go very low. We can also discuss sound waves, so again it's just the periodic variation of some property -- in this case we're talking about density, so we have high density areas and low density areas.
例如这是平均位置,在峰的位置水位高,在谷水位低,我们也可以,讨论声波它也是某种,量的周期变化,在这里我们,讨论的是密度,我们有高密度区和低密度区。
So since it's a component of the angular momentum, that means that it's never going to be able to go higher than l is, so it makes sense that, for example, it could start at and then l go all the way up to l.
因为,它是,角动量的分量,这意味着,它不会,比l大,这是很容易理解的,比如说,它可以从零开始,一直到。
It looks like we hit zero, but we actually don't remember that we never go all the way to zero, so there's these little points if we were to look really carefully at an accurate probability density plot, And then, for example, how many nodes do we have in the 3 s orbital?
但其实没有,记住,我们永远不会到零,如果我们,在概率密度图上,非常细致的看这些点的话,它永远不会到零,在3s轨道里,有多少个点呢?,2个,正确?
We can also do a similar thing, and I'll keep my distance from the board, but we can instead be holding x constant, for example, putting x to be equal to zero, and then all we're doing is considering the electric field as a function of t.
我们也可以做类似的事情,把x固定为一个常数,例如令x等于零,然后,考虑电场作为时间的函数,这种情况下,我们划掉。
