(Video) Salman Khan: So the hypotenuse is now going to be five.

於是這個直角三角形的斜邊就成了5

National Assembly: They create the Committee of Public Safety,

Start differentiating into effector and memory cells.

一個銀河。哇，那裡又有一個銀河

plus the 20 million dollars from the American manufacturer.

covering everything from basic arithmetic

We have a million students a month using the site,

一個月有百萬個學生使用我們的網站

watching on the order of 100 to 200,000 videos a day.

一天有一百到二十萬個影片被觀看

But what we're going to talk about in this

I want to talk a little bit about really just how I got started.

我想先談談我究竟是如何開始的

about five years ago I was an analyst at a hedge fund,

and I was tutoring my cousins in New Orleans, remotely.

And I started putting the first YouTube videos up

something that might give them a refresher or something.

And as soon as I put those first YouTube videos up,

當我把第一個 YouTube 影片放上去以後

actually a bunch of interesting things happened.

The first was the feedback from my cousins.

that they preferred me on YouTube than in person.

他們喜歡 YouTube 上的我更勝真人

And once you get over the backhanded nature of that,

而且一旦你忘記話中那諷刺的部份

there was actually something very profound there.

你便能聽見一件非常重要的訊息

that they preferred the automated version of their cousin

but when you actually think about it from their point of view, it makes a ton of sense.

但當你用他們的角度來想，事實上很合理

where now they can pause and repeat their cousin,

without feeling like they're wasting my time.

that they should have learned a couple of weeks ago,

they don't have to be embarrassed and ask their cousin.

They can just watch those videos. If they're bored, they can go ahead.

只要看這些影片就好。無聊了可以隨時關掉

They can watch it at their own time, at their own pace.

可以在自己想要的時間，用自己想要的速度看

And probably the least appreciated aspect of this

that you're trying to get your brain around a new concept,

在你的大腦嘗試理解一個新概念時

is another human being saying, "Do you understand this?"

另外一個人在你旁邊說“到底懂了沒有？”

And that's what was happening with the interaction with my cousins before,

但這就是我和我表弟互動時發生的

and I started getting some comments and some letters

from random people from around the world.

This is actually from one of the original calculus videos.

這個回應是給最早的那些微積分影片的

"First time I smiled doing a derivative."

“這是我第一次算導數會微笑”

And then in a response to that same comment -- this is on the thread.

You can go on YouTube and look at these comments --

I actually got a natural high and a good mood for the entire day.

and here I'm all like, 'I know kung fu.'"

And we get a lot of feedback all along those lines.
