Randi Weingarten of the American Federation of Teachers said the plan appears to place all the responsibility on teachers, but gives them "zero percent authority."

Meanwhile, the number zero is. Alright, it's all zeros 0 so I'll--just for consistency, use four of them here, but that's just an aesthetic.
同时,数字0呢,自然,全部是,只是为了一致性,我采用四个,当然仅仅是为了美感。
It doesn't go all the way to absolutely 100 percent ammoniazero hydrogen zero nitrogen if they were mixed together with the right ratios.
即使按适当比例混合,也不会出现全部氨气,没有氢气和氮气的情况。
Some have a "zero tolerance" policy where alcohol is banned from all buildings.

Remember this is our bond axis here, and you can see there is this area where the wave function is equal to zero all along that plane, that's a nodal plane.
记住这是我们的键轴,你可以看到在这些区域,波函数在这个面内全都是零,这是节点面。
But we know already from week zero that computers ultimately represent all information with numbers, and if they want to represent letters inside memory, well what do they do or what do they use?
但是自从上周我们已经知道,计算机最终是用数字来表示所有的,信息,如果它们要描绘,在内存中的字母,它们该怎么做,用什么方式呢?
5 And all you have is either zero or 15 because that is your resolution.
你说的得到的数据只有0或5,因为这是你的解决办法。
First of all, happiness is a positive sum game-- it's not a zero sum game.
首先,快乐是正和游戏-,不是零和游戏。
If the probability is 1 in 1,000 that a house burns down and there are 1,000 houses, then the probability that they all burn down is 1/1000 to the 1000th power, which is virtually zero.
如果一栋房子着火的概率是千分之一,然后假设有1000栋房子,那么这一千栋房子全都着火被烧掉的概率,就等于千分之一的一千次方,基本上就是0了
For example, if you started here and you did all this and you came back here, the average velocity would be zero, because you start and end at the same value of x, you get something; 0 divided by time will still be 0.
例如,如果你从这里开始运动,经过这个过程又回到这里,平均速度就是0,因为初态和末态的位移相同,你得到了什么呢,0除以时间还是0
It turns out after you do all the math, H it turns out to be delta H equals zero.
要等你做完所有的计算之后,才能知道结果,结果证明Δ
And what that corresponds to, if you recall, is the idea that in a perfect crystal at zero degrees Kelvin then you have no disorder at all.
如果你们能回忆起来的的话,这就意味着,绝对零度下的完美晶体,一点无序状态也没有。
So, the wave function at all of these points in this plane is equal to zero, so therefore, also the wave function squared is going to be equal to zero.
因此这里的,波函数平方也等于零,如果我们说在这整个平面上,任何地方找到一个p电子的概率都是零。
u=0 And it's approximately equal to zero for all real gas processes.
在所有理想气体绝热过程中Δ,对真实气体近似为零。
And then, it's, for all intents and purposes, falls to zero.
然后,无论如何,它会降到。
Yup, zero radial nodes. So, for a 2 p orbital, all the nodes actually turn out to be angular nodes.
没有,对于2p轨道,所有的节点都是角向节点。
Zero, all right?
得0分,对吧?
pV=RT p plus a over v bar squared times v bar minus b equals r t. All right if you take a equal to zero, these are the two parameters, a and b. If you take those two equal to zero you have p v is equal to r t.
我们就回到,也就是理想气体,状态方程,下面我们来看看,这个方程。
Well, all right, delta u is equal to zero for that.
好吧,绝热过程中。
You spin this big wheel and it rotates for a while and then it stops at one number, but obviously a random number, because this wheel of fortune had all the numbers from zero to one hundred.
你转动那个大轮盘,它会旋转一会儿,最后停在一个数字上,显然是一个随机数,因为幸运轮盘可以指向,0到100的的任何数
All right, so you can't get perfect efficiency, 0 but at least if you were able to go to zero degrees Kelvin, then you'd be all set.
好吧,你得不到完美的效率,但至少如果能把温度降到,那你就万事俱备了。
So, when the voltage difference between the plates is zero, or when we just don't have the plates there at all, the cathode rays are not bent, they just go right in a straight line, and they can be detected on this screen.
拐弯来测试它们是否带电,当两板之间电压为零,或者根本就,没有这两个板时,阴极射线是一条直线,它可以在屏幕上。
The atoms or molecules in the gas don't know that there are other atoms and molecules in the gas, and then you end up with this universal property. All right, so gases that have this universal property, even when the pressure is not zero, those are the ideal gases.
可以忽略,这样就得到了理想气体的性质,在有限压强下,依然能保持这些性质的气体,被称为理想气体,本课中我们把大部分气体,都作为理想气体来处理。
When delta G is zero, you know, it doesn't mean that you've got all of one side, all reactants and zero products or all products and zero reactants.
当dG等于零的时候,化学反应并不处在任何一边,例如全部都是反应物没有生成物,或者全部都是生成物而没有反应物。
So all that's left is negative T dS is less than zero.
只剩下TdS小于零。
All right, what we've already got that q is zero.
好,现在我们已经知道了q是零。
-- Else if n is greater than 4 and n is less than 6 -- 7 let's call it medium -- else if n is greater than or equal to 7, -- less than or equal to 10 -- let's call it "big" -- and if the user typed in zero or negative 10 or 20 or whatever, let's just use the all-inclusive else block and just say, "You picked an invalid number."
否则如果n大于4,并且n小于-,我们叫它为中间数--否则如果n大于等于,小于等于10--我们叫它为“大数“,如果用户键入了0或者-10或20或其它的,让我们用一个广泛的else子句,只需要说,“你选了一个非法的数字“
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。
