Anders Nilsson教授是我在瑞典皇家工学院时的指导老师之一，也是我的恩师益友。Nilsson教授是瑞典皇家工学院的Chair Professor，欧洲著名声学大教授，生前多次访问中国，与中国学者联系密切。Nilsson教授为人独立特行，幽默风趣，很多轶事趣谈。Nilsson教授仙逝时，我给他夫人Luciana写过邮件，粘贴于此，以做纪念。
I felt deeply sad after I read the letter from Luciana. I took a long walk alone the sea side to clean up my mind before I could sit down writing something. I never thought it would be like this. Anders never mentioned about his health condition during our so many communications not long ago. Only I felt is that he spent so much enthusiasms and efforts to a jasa paper, and this sort of hard working might affect his health. Just a month ago Anders prepared a long and good rebutter letter for our jasa paper, and I suppose he was fine at that time. But then in a message followed he told me that he was not able to answer the mail frequently for few months, I had bad feelings but I was afraid to inquire about it. I wish things are better off.
I expected to meet him at Tsingtao next summer at a forum to be organized by myself. Last time when Anders and Luciana revisited Beijing by attending ICSV21 in 2014. I regret not able to arrange better for his revisit. I imagined that I would have chance to have a better arrangement for Anders during his visit at my new location- Tsingtao.
I felt heavy loss of a wise advisor. Anders is an example of kindness and wisdom. Not only he explains me acoustical problems in every detail, but also encourages and enlightens me about life wisdom as a wise elder always does. In 5th of July, he wrote: “…For a group to achieve results there must be a strong and clever person leading the work. You are that person. Without a dedicated leader a group will soon disintegrate. For example, at KTH they are now reorganizing…” I was inspired very much by his words, though I knew that I am not so good as he described. He said this because he wished me to be an eligible leadership as he always demonstrated.
MWL is his child and he loves it very much. I could feel that he was extremely happy when he attended 40-year celebration of MWL. In August, 2017, he wrote: “…Last week MWL celebrated its 40 years. I was there. It was great fun to meet old PhD students, in particular Daniel and Erik. Many had come from afar, USA, China, Egypt and a number of European countries….” At this message, he even planned to visit china again! “…Now and then I feel I would like to visit China again. We even discuss combining a trip to Vietnam and Cambodia with a visit to China. Perhaps it is only wishful thinking. We have to decide soon...”
In another letter, he explained me the photo taken in 1987. I loved the photo very much and intended to make a similar photo for my group at QUT. “…My first picture of my presentation from the MWL jubilee is taken in front Gadefelts summer house outside Stockholm. The photo is from June 1987 and I had just taken over the chair from Gadefelt who had retired. Mats is missing. Leif is at this time doing his master thesis, the others are PhD students. HP was also registered as a PhD student all his life but he never did any research or took any courses and consequently he never got a PhD. HP is a strange man who completely lacks confidence in himself. The first ones to get doctoral degrees were Mats and Hans. That happened in 1989. The man with the scythe is Johan Leander. He got his PhD , became a docent(associate professor) at MWL and professor at the Swedish Defence University. He later committed suicide like both his mother and brother had done before him. A very tragic family story. At the end of I said I was living happily in Italy. The photo is from Portofino which is very close to where we live. It is a beautiful place. There a many former old small fishing villages along the coast. Many are very charming. By walking seven minutes, I can reach two of them. Next time you come you should visit the coast. Whenever I have spent some time inland I always feel a relief seeing the sea open up to the horizon…” The suicide story scared me and therefore I gave up the idea to make a similar photo for my group. Apparently he knew his graduate students very well. I could feel how he loved MWL!
Of course, he loved china and the cultures always, in a letter, he wrote: “…In your mail you mentioned a quote from Confucious. During my talk at MWL I also mentioned Confucious and of course I showed the photo of you, Confucious and me outside the Imperial college in Beijing…”
I always believe that the depart of a body does not mean that of a soul. One old proverb said that as one piece of fuel is consumed, the flame passes to another. I wished that someday I would be able to talk with a wise soul as Anders again, probably in another space-time, or in other ways, as a result of serendipity.
A soul destination
I'm sure I have found a home for my soul It's on the three mountain roads On the left is the elegant Hui-Yin Temple On the right is the silent Yu-Qian shrine
When tourists return I floated down the stream Through woods and lawns There are stone railings, arch bridges and floor pavilions And came to the open lake
At this moment The night is clear and scant-started The water is clean Wise spirits are sitting around Tell the story that the world has never known
