When I was in high school our physics teacher gave us a challenge that involved making a paper air plane of any shape. The only objective was to get it to fly as far as possible. I had some paper air plane making skills so I made the best plane I could and it flew pretty far.
当我还在上高中的时候，我们物理老师布置了一项挑战：用一张纸做一架飞机，形状随意，目标就是能够使它肥的越远越好。我掌握了一定的飞机制作技巧，所以我确信我可以造出最好的飞机也能使它飞到相当远的距离。
One guy made the greatest, yet simplest paper airplane of all time. He stood there at the starting line with a regular piece of paper. Some classmates scratched their head while silently chuckling to themselves. Moments later he took the flat piece of paper, crumpled it up, and threw it down the hall way.
有个人却作出了最简单确是最好的飞机来。他那这一张普通的纸站在起始线上。一些同学轻挠头低声笑着，一会之后他拿起那张纸，将它揉成团，扔到走廊那。
He beat the class with ease.
他轻松的打败了全班同学。
Some of the students got mad and said that he cheated.
一些同学非常恼火直呼他作弊。
The physics teacher said, "How so? I said it could be any shape. A paper ball is indeed a shape."
但是物理老师却说：“那又怎样，我说过飞机可以是任何形状。纸球显然也是一个形状。”
I still regard this classmate as a genius.
我一直将这个同学视作天才。

There used to be a ECE professor next door few years back,
几年前有一位电子工程教授住在我家隔壁。
We used to live in a neighborhood with too many houses in a streak, Cable man goes to every house for bill connection, except our neighbor's
我们过去住的地方，一道有许多邻居。电缆工人会到每一家收取有线电视费，除了我家邻居。
They never paid for cable connection, I was very young to understand what he was saying , but it said something like this,
他们从没缴纳有线电视费，我那会还小不懂他在说什么，但意思大概是这样的：
Beta, Signals are ever where, it's you who capture them and use them in the way you want.
贝塔，信号随处都有，这要看你如何抓住它们利用它们。
He constructed an antenna that captured signals from cable wires , and that gave them access to all channels
他搭起了一个天线来接收电缆信号，他们也因此可以收到很多频道。
Now this was almost 15 years back, dish TVs are recently introduced but him using the antenna for cable connection is something I cannot design even today.
这发生在十五年前，那会卫星电视还没普及，他就已经能够搭天线接收信号，就算现在的我也办不到。
Note:- I am not ece student to exactly understand what was done but as a 9 year old kid, that was the most intelligent thing I ever saw.
我不是一位电子工程学生并没有完全理解原理，但是对于一个九岁的孩子来说，这是我见过的最机智的一位
