Hungarian researcher joins Chinese Academy of Sciences as first Hungarian foreign member
Scientific relations between Hungary and China are tied stronger as the Chinese Academy of Sciences elects Gábor Stépán, BME’s professor as foreign member.
Gábor Stépán, professor of the Department of Applied Mechanics at BME’s Faculty of Mechanical Engineering was elected as foreign member of the Chinese Academy of Sciences this year. He joins the nearly 150-strong group together with Konstantin Novoselov, Nobel Prize winner, awardee of BME’s John von Neumann Professor title. BME.hu asked Gábor Stépán about the road to his academy membership.
What was the road like to your election as foreign member of the Chinese Academy of Sciences?
It was a long journey and not only because how far China is from here. I started correspondence with a professor from Wuhan as early as the 1980s who wrote publications about the nonlinear vibrations of machine tools during his postdoctoral studies in England. That was when I heard the news about China’s open-door economic policy and the intensive development taking place in universities. Chinese scientists started to visit Western Europe and the USA, I met several researchers at science conferences and I received more and more invitations to Chinese conferences in dynamics. However, my first visit to China was only in 2002 because I was somewhat concerned about travelling within such an enormous country. I first went to Nanjing (Nanking according to the Southern accent), the old Southern capital where an internationally well-known research team at the university was working on the stability, vibrations of time-delay mechanical systems. I attended conferences there again in 2006 and 2012. The progress I could see that both the university made in professional terms and the city itself made was simply shocking. The most prestigious event of our profession, the International Congress in Theoretical and Applied Mechanics took place in Beijing (the Northern capital) in 2012; the appointment as host reflected the development of China’s research in mechanics and its recognition.

What collaborations have you had in these nearly 40 years?
In 2012, the first call for applications under the Chinese and Hungarian science and technology cooperation scheme was announced where we won with the research team from Nanjing and BME’s Department of Applied Mechanics. From this time, we had yearly meetings with several Chinese researchers spending 1 to 3 months at our department and several of our teachers, researchers and PhD students taking study tours lasting 2 to 4 weeks at the Mechanics Institute of the Nanjing University of Aeronautics and Astronautics.

There were numerous shared achievements and joint publications that later strongly benefited the dissertations of both the Hungarian and Chinese PhD students. We co-organised international symposia, I won a number of Chinese projects intended for foreign applicants and we built professional relations with Chinese companies. Every two years, I led intensive summer courses for MSc and PhD students at Nanjing University, which were attended both by students and teachers from Beijing in 2018.

I received an honorary professor title from the university and I spoke at plenary sessions at international conferences in dynamics and production technology. With a team of PhD students from our department, we entered their international invention competition where we won the third prize. In the meantime, the visits of our Chinese colleagues to Hungary offered the opportunity for them to attend European conferences, to be involved in the European research community.

The list of results achieved with tiny and persistent efforts just goes on including more and more projects with other Chinese universities from Hefei, Xian and Shanghai and many other cities where students spending longer periods of time in Hungary and obtaining their PhD degrees in China built their careers. There was a French PhD student who could not return to Nanjing because of the Covid pandemic but, in view of our good cooperation, the Chinese research centre agreed to pay his scholarship to us and so he pursued his research at us for one and a half years, which again resulted in joint publications. He is about to defend his dissertation in Nanjing.
What other connection points have you identified over these decades?
Our cooperation had a historical basis that was a surprise to me and that was a strong inspiration, almost an obligation. On the one hand, I did not know that everybody in China knows the poem Freedom, love by Sándor Petőfi as they must learn about it in school and I was also unaware how much the Chinese engineering science community respects Tódor Kármán.
During my one year in Pasadena, I collected a lot of information about Tódor Kármán in 1995, who was one of the founders of the Jet Propulsion Laboratory there, which is the centre of space research in the USA to this day. The professors who met Kármán in person told me interesting stories about Hsue-shen Tsien, who was believed to be his best Chinese student. Tsien returned to China in 1955 and became the head of the Chinese rocket programme and even the space research programme and lived to see the first Chinese space station being placed in orbit.

It is therefore no wonder that Tsien’s photo is there in the corridors of every aeronautics institute but I was surprised to see Kármán’s image next to his. Tsien always spoke very highly of Kármán’s outstanding expertise and openness. Xuji Fan, the founding professor and first rector of the Nanjing University of Aeronautics and Astronautics was also Kármán’s student but he left Pasadena and returned to China immediately after graduating in 1939. As an interesting fact, a landing unit from one of China’s space missions landed on the far side of the Moon in the von Karman crater offering another opportunity to the Chinese press to mention Tsien and Kármán’s story. When I take my Chinese guests on a tour in Building K, we always stop in the auditorium at the sculpture of Donát Bánki and I tell them that he was Kármán’s teacher who helped him start his career and I also show them the wind tunnel of the Department of Fluid Mechanics bearing Kármán’s name.

Were there any indications suggesting your election as foreign member of the Chinese Academy of Sciences?
The Chinese Ministry of Science and Technology invited me just before the Covid pandemic to a work meeting intended to evaluate the organisation of China’s science sector. The most interesting part of these sessions for me was the involvement of three (an English, an Israeli and a French) Nobel Prize winners and my conversations with them. Although I did not think at the time but this invitation may have indicated that my work was being followed within China’s technical science sector.
How important is this membership for you and does it involve any regular commitments?
To be honest, I was not fully aware of the functioning of the Chinese Academy of Sciences, its election system but I then read their charter and the way it works seems very similar to the system of the English Royal Society, which obviously has a crucial impact on how the Hungarian Academy of Sciences and other academies function. As a rule, academies choose their foreign or honorary members from the members of other academies who, apart from being professionally highly accomplished, have significant scientific relations with the specific academy and its members. The six divisions of the Chinese Academy of Sciences, which was established in 1955, cover only natural science disciplines, its membership of approximately 800 is very small compared to the size of China and it has only about 150 foreign members. This year, 30 new foreign members were elected including 9 English, 3 American, 1 Norwegian, 1 Swedish, 1 Canadian and 1 Australian member from their respective national academies and for the first time, one academy member from Singapore and one from Hungary. Three of them are members of the European Academy of Sciences, one is the recipient of the Fields Medal. The new members include two Nobel Prize winners: one of them is Konstantin Novoselov, who was given the von Neumann Professor title by BME last year when he also delivered a presentation at the university.
Next June, I will need to attend the general assembly meeting of the Chinese Academy of Sciences in Beijing where I will deliver my inaugural address. This system also follows the traditions of the Royal Society as a membership only becomes official both in Hungary and China when a newly elected member delivers his/her speech.
