是什么粉笔得到了无数教师的青睐?

Why the World’s Best Mathematicians Are Hoarding Chalk

[欢快的音乐]
(upbeat music)
有一个关于羽衣粉笔的传说 就是它不可能写出错误的定理
– The legend around thischalk is that it’s impossible to write a false theorem.
我猜测这个特殊的材料是天使之泪
– I assume the special ingredients is angel tears
顶尖学校的数学家经常使用它
Mathematicians from the top of the school very frequently use it
它受到崇拜式的欢迎
– It’s a cult favorite.
我一用就迷上了它
– As soon as I use it I was a convert.
粉笔是数学界里保存最好的秘密之一
– The chalk is one ofthe best kept secrets in the math world.
它是粉笔界的劳斯莱斯
– It’s the Rolls Royce of chalk.

[用粉笔书写中]
(chalk scratching)
羽衣是日本粉笔的一个牌子
– Hagoromo is a brand of Japanese chalk.
它在黑板上划过的线条是难以用语言形容的
The way it flows on a board is a bit hard to describe in words.
它很难买到
– It’s really hard to get.
它只有在日本才能买到
You can only get it from Japan,
而且需要日本人给你带回来
you need a Japanese person to bring it back for you.
它是我在参观东京大学时发现的
– I discovered it when I went to visit the University of Tokyo
那里的一个教授告诉我
and one of the professors there and said to me
你知道吗 我们有比美国更好的粉笔
you know, we have better chalk than you do in the States
我说 得了吧 粉笔不就是粉笔啊
And I said,oh go on, chalk is chalk.
所以我试了一下
And so I tried it out,
结果惊讶的发现他是对的
and I was surprised to find that he was right.
我试过后 觉得它是与众不同的
– I tried it, and Ithought it was phenomenal.
它的密度大 擦的也极其干净
It’s the densest, it erases the cleanest,
只留下最好的线条
it leaves the nicest line.
如果你用差的粉笔 你必须用力按
– If you use bad chalk often you have to press
否则很难看清你写的是什么
really hard for anyone to see what you’re writing so using
用羽衣粉笔在好的黑板上写
Hagoromo on a good board, it doesn’t really
你不会感到很难写
feel like you’re working hard to write.
当我教学时 我精神抖擞 充满自信
– When I’m teaching I get a feeling of energy, confidence,
粉笔对我帮助很大
and the chalk absolutely helps.
[粉笔发出咔哒声]
(chalk clacking)
慢慢的 数学界也开始关注它
– Slowly the math worldhas become aware of this,
它在某些圈子里成了一种时尚
and it became a bit ofa fad in some circles.
[欢快的音乐]
(upbeat music)
大概四年前就有消息指出
It was like maybe four years ago the word came out
公司即将破产
that the company wasgoing out of business.
我开玩笑的说 这是粉笔界的大灾难
I sort of jokingly referredto it as a chalk apocalypse.
因此我立即尽可能多储备些
So I immediately startedhoarding up as much as I could.
我买了三盒羽衣粉笔
– I ordered three boxesof Hagoromo and kept it in
将它放在我的办公室里 而且非常节省地使用
my office and used it very sparingly.
我其实应该多买些的 但我的朋友
– I should’ve bought more butI have friends that bought
买了一盒又一盒粉笔
boxes and boxes and boxes of the stuff.
他们可能已经为自己余下的职业生涯作好了准备
They might very well be set for the rest of their career.
我们有1500根
– We’ve got like 1,500 sticks.
就算一天用四根也能用很久
That’s a lot of days, four sticks a day.
我想这些粉笔够用了
I think I’m gonna make it.
我家里约有十年的供给量
– I have probably a 10-yearsupply still at home.
我估算出我10到15年能用多少盒
– I calculated how many boxes would I need to last for 10 or 15 years.
我不想成为粉笔经销商
I didn’t wanna become a chalk dealer,
但我的确喜欢这个想法
but I did like the idea
我可以当部门的“第一根免费”的粉笔经销商
that I could be the first stick is free chalk dealer on the block in my department
我经常向八到十位同事出售粉笔
– I was probably sellingit regularly to maybe eight to 10 colleagues.
我打开办公室柜子
I would reach into my cupboard in my office
拿出另一个盒子 在办公室跟对方完成交易
and pull out another box and we’d do the deal in my office.
我们都对使用羽衣粉笔上瘾
we all had a chalk fix.
并且一直如此
And we still do.
[温柔的音乐]
(gentle music)
最初的羽衣粉笔正在逐渐消失
– The original Hagoromochalk is slowly disappearing.
几年前 一家韩国公司买下了他们的配方
A few years ago, a Koreancompany bought their formulas
并在韩国完美的复制了出来
and did the best job offaithfully reproducing it in Korea.
这让我产生一种复杂的情绪
– It was mixed emotions.
我很高兴 知道它还在继续生产着
I was happy to know thatit would still be made.
却又发现我没有我想的那样聪明 这让我有点失望
But I was a little disappointedthat I was less clever than I thought I was.
[温柔的音乐]
(gentle music)
在很多方面数学就像工艺
– In many ways mathematicsis like craftsmanship,
一方面像艺术 另一方面又像科学
in some ways it’s like artistry; in some ways it’s like science.
但利用黑板给出一堂精彩的讲课 才是一门真正的艺术
But there’s a real highcraft side to getting a beautiful lecture on a blackboard.
数学家们彼此都钦佩这样
Mathematicians admire this in each other
并且为了实现它 喜欢用上最好的工具
and like to use the best tools for it.
它有极大的价值
– There’s incredible valueto this
但它的价值是通过用完它得到实现的 而不是通过囤积
but the value is in using it up, not hoarding it.
[温柔的音乐]
