很久沒有遇過好的導師，在我最後一個semester的課程裡給我遇到一個。

一個好的導師，說話清楚明快，有內容，有層次，以最簡單的說明最艱深的道理，其實還有一點非常重要，唔悶﹗以下是堂上笑話兩則：

'In 1980's, the American scientist found that their ball pen didn't work in space due to insufficient gravitational force to pull down the ink inside. They can't write down anything on a paper! Eventually, they invented a ball pen which was"pressureless" inside and the ink came out successfully! A year after, another Russian spaceman has a more wonderful discovery. Rather than using the "pressureless" ball pen, he used pencil!!"

"Students are the only customer in the world who pay the money and don't want to get anything!"

少有地很專心聽完整個課堂。
