Chia-Chiao Lin

Chia-Chiao LinChia-Chiao Lin, of Fuzhou, Fujian Province, was born in Beijing on July 7, 1916. In 1937, he graduated from Tsinghua University Department of Physics, and then served as teaching assistant there. In 1940 he went abroad to University of Toronto, Canada for a further study and obtained a master degree in 1941. In 1944 he graduated with a doctor degree from California Institute of Technology and since 1947, he undertook associate professor, professor, institute professor and emeritus professor in Massachusetts Institute of Technology. He joined the National Institute of Arts and Sciences in 1951, and joined the US National Academy of Sciences in 1962. In 1994, he was elected as an academician of Chinese Academy of Sciences. Tsinghua University invited him as an honorary professor in 1979, awarded him an honorary doctorate degree in 1987, and employed him as a distinguished professor in November 2001. In August of 2002, Chia-Chiao Lin settled in China and was appointed honorary director of Zhou Peiyuan Center for Applied Mathematics, Tsinghua University. In January 2013, Prof. Chia-Chiao Lin died in Beijing, aged 97.

Professor Lin is internationally recognized authority in mechanics and applied mathematics. From 1940s, his work in stability of parallel flows and in theory of turbulence fluid motivated a generation's research and exploration. From the 1960s, he entered the study of astrophysics, founded the well-known spiral density wave theory, conquered the problem which puzzled astronomers for decades. In applied mathematics, his contribution is particularly important in the development of method of analytical characteristic line and WKBJ method. In mathematics, his most outstanding contribution is his proof of the existence theorem of the differential equation, and he completely solved the long-term controversy in Heisenberg’s paper. He is an outstanding leader of contemporary applied mathematics.

Professor Lin had served as chairman of the Committee of Applied Mathematics of American Mathematical Society, president of the Society of Industrial and Applied Mathematics (SIAM). He won the Timoshenko Medal from the American of Society of Mechanical Engineers, the National Academy of Sciences Awards in Applied Mathematics and Numerical Analysis, and Fluid Dynamics Prize from the American Physical Society.

1916年7月7日生于北京,原籍福建省福州市。1937年毕业于清华大学物理系,随即留校担任助教。1940年赴加拿大多伦多大学深造,1941年获多伦多大学硕士学位,1944年获美国加州理工学院博士学位。从1947年起,历任麻省理工学院副教授、教授、学院教授、荣誉退休教授。自1951年起成为美国艺术与科学院院士,1962年起成为美国国家科学院院士。1994年当选为中国科学院外籍院士,1979年被清华大学聘为名誉教授,1987年清华大学授予他名誉博士学位,2001年11月被聘为清华大学教授,并于2002年8月回国定居出任清华大学周培源应用数学研究中心名誉主任。2013年1月,林家翘教授在京逝世,享年97岁。

林家翘教授是国际公认的力学和应用数学权威。从40年代开始,他在流体力学的流动稳定性和湍流理论方面的工作带动了一代人的研究和探索。从60年代起,他进入天体物理的研究领域,创立了星系螺旋结构的密度波理论,克服了困扰天文界数十年的“缠卷疑难”。在应用数学方面,他的贡献是多方面的,其中尤为重要的是发展了解析特征线法和WKBJ方法。在数学理论方面的贡献,最突出的是他证明了一类微分方程中的存在定理,彻底解决了海森伯格论文中所引起的长期争议。他是当代应用数学学派的领袖人物。

林家翘教授曾担任美国数学会应用数学委员会主席、工业和应用数学协会主席。他曾获得美国机械工程师学会Timoshenko奖,美国国家科学院应用数学和数值分析奖,美国物理学会流体力学奖。
