Here is an interesting story, found at Teaching这里是一个有趣的故事,发现在教学 Sells出售 .

Back when NASA started launching manned spacecraft in the 1960s, they found out that the astronauts couldn’t use pens to write with while in space.回到开始时,美国航天局发射载人飞船,在20世纪60年代,他们发现指出,宇航员无法使用钢笔书写,而与在太空中。 The ink wouldn’t flow down through the pen in a zero-gravity environment.油墨不会流下来,通过用笔在一个零重力的环境。 NASA decided to retain a man named Paul Fisher to design a pen that would work in space.美国航天局决定保留一名叫保罗费舍尔设计一个笔会的工作空间。

A mere $1.5 million later, they had a solution.仅150万美元,后来,他们有一个解决办法。 NASA now had a pen that worked in zero gravity, in a vacuum, and in a drastic temperature range.美国宇航局现在有一个笔工作在零重力,在真空中,并在急剧的温度范围内。

The Russian cosmonauts had the same problem, of course.该俄罗斯宇航员有同样的问题,当然。

So they used a pencil.因此,他们用一支铅笔。

Now, this anecdote isn’t historically accurate, and has become a bit of an urban legend.现在,这个故事是不是能准确再现历史,并已成为一个位元一个城市的传奇。 The truth is both the US and Russia used pencils at first, and Paul Fisher independently created the pen and sold 400 of them to NASA for a song.事实是,无论是美国和俄罗斯用铅笔在第一,和保罗费舍尔独立制作的笔和出售的400他们为美国航天局的一首歌。 The reason the exaggerated story is so widely embraced, though, is because it rings true.原因夸张的故事是如此广泛接受,虽然,是因为它真正的戒指。

We often expend large amounts of time and effort creating elaborate solutions to problems when a simple answer is right under our noses.我们经常花费大量的时间和精力创造阐述解决问题时,答案很简单,就是权利下,我们的鼻子。
