So math -- or,as the British call it,maths -- is still not everyone's favorite subject even with the latest technology to teach it.

I don't want anybody to quit this class because they're worried about math or math notation.
我不希望你们因为对数学,或是数学符号的恐惧而放弃这门课
so that's great that a lot of people have enough time to be in something that's not math or science related.
很多人投入了时间,来做与数学或科学无关的事情,这真的太好了。
These include math,science, writing and United States history or government.

I just go down the list selecting the smallest person at a time and then I repeat, repeat, repeat but when we actually did out the math or kind of reason through it, the running time, the asymptotic running time of bub-- of Selection Sort was also what?
只需要遍历列表,每次找出最小的元素,然后重复上述步骤,但从数学角度看,选择排序的时间复杂度,又是多少呢?
Charles Bolden, the head of the US space agency, NASA,and Lisa Jackson from the Environmental Protection Agency,or EPA, came to this Washington,DC middle school to encourage these youngsters to focus on math and science careers.

Perhaps you think you have come to math or physics.
也许你认为你已经学好了数学或者物理。
We don't always want to go and solve the Schrodinger equation, and in fact, once we start talking about molecules, I can imagine none of you, as much as you love math or physics, want to be trying to solve this Schrodinger equation in that case either. So, what Lewis structures allow us to do is over 90% of the time be correct in terms of figuring out what the electron configuration is.
我们并不想每次都去解薛定谔方程,而且实际上,一旦我们开始讨论分子,我可以想象,你们中没有一个人,不管你有多么热爱数学或物理,会想去解这种情况下的薛定谔方程,总之,路易斯结构能让我们,有超过,90%,的概率判断出正确的,电子排布。
Not just in sort of mathematical things like chess or math, there are, as you know, programs that can write music.
不止是下棋或数学这类跟数理有关的事,你知道,有些程序甚至能创作音乐
And so this is not like a math problem set or a physics problem set. Or, like a high school physics lab, where we all know what the answer should be, and you could fake your lab results anyway.
或是物理问题集合,又或者是高中的物理实验室,我们对这些问题都有确切的答案,或者你可以把你的实验结果改成正确的,有些事情是不能明确界定的。
Generally,you don't have to worry about optionality or call provisions and so it's math.
一般来说,没有必要去担心期权性风险,或赎回条款,就只是数学游戏
So always amazing to us how we go into the problem, our eye or mind can see one class of solutions, but the math will tell you sometimes there are new solutions and you've got to respect it and understand and interpret the unwanted solutions, and this is a simple example where you can follow what the meaning of the second solution is.
解决问题的方式总能让人惊喜不已,我们的眼睛或思想可以看见一类解,但数学有时会告诉你还有新的解,你不能忽视它,而是解释这些不期而至的解,这只是一个简单的例子,由此你可以理解第二个解的意义
Finally this may be news to you, but this is not English 10A or Math 55, meaning you'll not have to read as much as you will read for 10A or for a history class, and this class is not as difficult as Math 55 so you rest.
最后这个可能对你们来说有些新,但这不是10A号英语课和55号数学课,也就是说你不用像10A号课或者历史课那样做大量的阅读,也不像55号数学课一样难,所以你们可以轻松些。
Now, unlike high school math or in algebra Z where you call things X and Y and Z, in programming, in computer science, you're actually dealing with humans where it's useful to have a variable name that's more descriptive than X and Y and Z.
不像高中数学或者代数中,称为X和Y和,在程序设计和计算机科学里,你实际上是在和人打交道,在这里有个描述性比xyz更强的,变量名称是很重要的。
So a bit of uninteresting math, a bit of focus on sizes of types, but any questions on syntax or concepts thus far before we now put this to the test?
一些比较无趣的数字,一些关于类型的大小,在我们现在进行试验之前,你们对这其中的语法或概念有什么问题吗?
Or, you like math now but then you lose your taste in math, and you become the kind of person perhaps who's interested in Chinese poetry, whatever it is.
或者你失去对数学的原有兴趣,变成那种,对中国诗词感兴趣的人。
And then 50 or 100 years pursuing math as your career.
然后花50或100年从事数学。
Yet even there, when I imagine an eternity of thinking about math--or for that matter, an eternity of thinking about philosophy, which I obviously like even more than math-- the prospect seems an unattractive one.
即使如此,当我想到让我永远,思考数学问题,或者说,让我永远思考哲学问题,显然和数学相比,我更钟情于它-,但这个提议也变得无趣。
And the good news was we didn't have to worry about how math did square root or anything like that, we just got it and we used it.
也可能是其他数,好消息是,我们不必担心math函数是怎样开方的,我们只要使用它就好。
