a stream of electrons was fired through two tiny slits.towards a detector.
一束电子穿过两道裂缝 往一组侦测器射出
common sense tells us the electrons should hit the detector.
根据常识 电子射中侦测器的区域
in this two highlighted areas right behind the slits.
应该是裂缝正后方的两条明亮区块
But that's not what happened.
但实则不然
Instead,the detector picked up a pattern of not just two lines.but many.
相反地 侦测器不只有测得两条线 而是很多条
This is simply not what anyone expected electrons or any small lumps of matter to do.
这实在迥异于大家对电子 或任何微小粒子的预期
The tiny electrons appeared to be define the laws of physics.
微小的电子似乎违反了物理定律
To get your head around just how weird this really is.
为了让大家了解这到底有多怪
Let me scale up the electrons to something a bit more familiar.
我们把电子换成较熟悉的东西
like a soccer ball.This striker is about to take a free kick.
好比足球 这名前锋准备罚踢任意球
Obviously,he'll do his best to hit the ball,pass the defensive wall and the goalie,and into the net.
他当然会尽力让球越过人墙和守门员而破网
And they will do their best to stop that from happen.
而对方则会尽力不让他如愿
So far it all make sense.
目前为止一切合理
But apply the rules of the subatomic or quantum world.
但若应用亚原子 也就是量子规则
and things work differently.
万物的作用原理就不相同
And that's why physicists started to get very worry.
也正因如此 物理学家开始非常担忧
