COVER STORY 封 面 故 事 L: David Chung-Laung Liu Y: Andrew Chi-Chih Yao F: Frances Yao J: Journalist Liu: “The ‘Yao Class’ is as important as the ‘Qian Class’ ” Y: I studied under Prof. Liu from 1973 to 1975 at the University of Illinois. I was very fortunate to have such a good role model as Prof. Liu at a young age. He is a well-versed scholar and he knows how to educate students according to their strengths. For example, for students who didn’t have a lot of systematic ideas but were diligent and had a solid grasp of the fundamentals and theories, he would assign some tasks that suited their strengths; for those who had original ideas, he would give them a lot of freedom and would encourage them to think independently. That’s why his students have achieved success in different ways. He saw the strengths in every student and helped them achieve maximum potential. This has had a huge in!uence on me, especially for my teaching at Tsinghua University in recent years. 劉：劉炯朗 姚：姚期智 儲：儲楓 記：記者 劉炯朗：「姚班」就像當年的 「錢班」一樣重要 姚： 我1973到75年在伊利諾大學的時候在 劉教授門下。劉教授除了學問好，還懂 得怎樣造就人才。我對他印象很深，是 我早年就看到一個好老師的典範。劉教 授最重要的就是因材施教，他的學生不 見得全部數學都特別好，但每個人都有 長處，可能有些人沒有什麼觀念性的想 法，但基本功不錯，也很用功，那劉教 授就給他一些能用數學表達出來的問題 去做；而對於自己有想法的學生，劉教 授就會給他們很多自由，鼓勵他們獨立 思考。所以他的學生取得了各式各樣不 同的成功，這對我影響很大，尤其是我 最近幾年在清華教學生。劉教授當年的 風範，對我有非常大的影響。 Prof. David Chung-Laung Liu 劉炯朗教授 4 umagazine | issue 07
