Under-nutrition--now I'm going -this slide has a lot of information on it and I'm going to come back to it in the class where we talk about hunger, but I show it today because of course undernutrition can affect every single system of the body and can have devastating consequences on people's health.

But Ian Hacking, being a good historian, thought that someone must have had some concept of probability going before even if they didn't quote it as a number the way-- it must have been in their head or in their idea.
但是这位优秀的历史学家伊恩·哈金认为,一定有人在更早时候就用过概率这个概念,即便他们没有用数字来表述,但他们一定有过类似的想法
That goes back to that idea of sort of discipline coding. It's easy to have assumptions about what you think are going to come into the program when you writ it. If you really know what they are use them as search, but if you think there's going to be some flexibility, you want to prevent the user getting trapped in a bad spot, and exceptions as a consequence are a good thing to use.
这又回到了规范编码的想法上来了,在你写代码的时候考虑,什么会进入你的代码的思考是简单的,如果你真的知道,他们是用他们来做搜索的,而你希望有一定的灵活性,你想要阻止用户,陷入一个艰难的境地,那么异常是非常实用的。

So that explains probably most of the confusion here and you just want to be careful when you're reading the problems that that's what you read correctly. I think 4 everyone would now get the clicker question correct.
这可能解释了大部分人的混淆之处,你们读题目的时候一定要仔细,我相信现在每个人都能回答正确了,第三激发态,n等于。
I can't rely on Professor Guttag if I give this- if this code to him, I can't rely on him to type in a float. Actually I can, because he's a smart guy, but in general, I can't rely on the user-- I wouldn't do it right to see if you did.
当Guttag使用这段代码的时候-,我不能相信他一定会输入一个浮点数,实际上我能因为他很聪明,但是总体上来讲,别相信用户一定会按照规则来-,我会故意做错来试试你的程序的。
So, that is a tricky problem to begin with because if you take this formula here, it tells you y if you know t, but no, we're not saying that.
以这个问题刚开始的时候有点难度,因为如果你要用这个公式,求y的时候就一定要知道t,但是,我们不知道
Remember, you've got to keep track of the sign of acceleration, so if you're picking up speed towards the ground, a is negative, so it will be g plus a, but a is a negative number.
记住,一定要注意加速度的符号,所以当你加速下降的时候,a 是负的,还是 g 加上 a,但是 a 是负数
