I decided to speak on the special qualities of traditional Chinese mathematics. The mathematician, Professor Oppenhiren, who was present at the seminar, was very interested and encouraged me to continue in the history of Chinese science and said that he was willing to be my supervisor.
我於是講了「中國傳統數學的特色」，當時在座的數學教授奧本涵爵士聽後感興趣，鼓勵我往中國科技史發展，並願意作我的指導教授。
