钱伟长
钱伟长(1912年10月9日-2010年7月30日)，江苏无锡人，世界著名科学家、教育家，杰出的社会活动家。
1912年10月9日，钱伟长出生于江苏省无锡，父亲是国学大师钱穆的长兄钱挚。1925年，先后在无锡荣巷公益学校、无锡县立初中、无锡国学专修学校(苏州大学前身[1] )读书。1928年，父亲病逝后，在苏州上学读高中，学习数理化和西洋史。
1935年清华大学物理系毕业后，考取清华大学研究院。1940年赴加拿大多伦多大学应用数学系学习，主攻弹性力学，1942年获多伦多大学博士学位。1946年回国后，应聘为清华大学机械系教授，兼北京大学、燕京大学教授。
1946至1948年，参加了反美扶日、反内战、反饥饿、反美援面粉等进步运动。1954年，提出了"圆薄板大挠度理论"(1956年获国家科学奖二等奖)。1955年被选聘为中国科学院学部委员(院士)。1956年当选为波兰科学院外籍院士。
1957年，中国力学学会成立，任副理事长。1957至1976年，从事飞机颤振、潜艇龙骨设计、化工管板设计、氧气顶吹的转炉炉盖设计、大型电机零件设计、高能电池、三角级数求和，以及变分原理中拉格朗日乘子法的研究。
1982年，"广义变分原理的研究"(1979年完成)获国家自然科学奖二等奖。同年，邓小平在中央组织部关于同意钱伟长担任上海工业大学校长的请示报告上批示：他的任命不受年龄限制。1983年1月19日，钱伟长到任上海工业大学校长。
此后陆续担任上海大学校长，漳州职业大学名誉校长，沙洲职业工学院名誉院长，南京大学、南京航空航天大学名誉校长，江南大学名誉校长、名誉董事长，暨南大学名誉校长、董事长，扬州大学名誉董事长，上海大学附属中学名誉校长，天津市耀华中学名誉校长，重庆交通大学《应用数学与力学》杂志主编，上海市欧美同学会名誉会长，中国海外交流协会会长，中国和平统一促进会会长等职务。
2010年7月30日6时20分在上海逝世，享年98岁。遗体于2010年8月7日在上海龙华殡仪馆火化。
钱伟长兼长应用数学、力学、物理学、中文信息学，在弹性力学、变分原理、摄动方法等领域有重要成就。从义理到物理，从固体到流体，顺逆交替，委屈不曲，荣辱数变，老而弥坚，这就是他人生的完美力学！无名无利无悔，有情有义有祖国。

Qian Weichang (October 9, 1912 - July 30, 2010), a native of Wuxi, Jiangsu, was a world - renowned scientist, educator, and outstanding social activist. On October 9, 1912, Qian Weichang was born in Wuxi, Jiangsu. His father was Qian Zhi, the elder brother of Qian Mu, a master of Chinese traditional learning. In 1925, he studied at Rongxiang Public School in Wuxi, Wuxi County Junior High School, and Wuxi National College (the predecessor of Soochow University[1]). In 1928, after his father's death, he went to high school in Suzhou, studying mathematics, physics, chemistry, and Western history. After graduating from the Department of Physics of Tsinghua University in 1935, he was admitted to the Graduate School of Tsinghua University. In 1940, he went to the Department of Applied Mathematics at the University of Toronto in Canada, majoring in elasticity. He obtained his doctorate from the University of Toronto in 1942. After returning to China in 1946, he was employed as a professor in the Department of Mechanical Engineering at Tsinghua University, and also served as a professor at Peking University and Yenching University. From 1946 to 1948, he participated in progressive movements such as the anti - American support for Japan, anti - civil war, anti - hunger, and anti - American aid in the form of flour. In 1954, he put forward the "Theory of Large Deflections of Circular Thin Plates" (which won the second - class National Science Award in 1956). In 1955, he was elected as a member (academician) of the Chinese Academy of Sciences. In 1956, he was elected as a foreign academician of the Polish Academy of Sciences. In 1957, the Chinese Society of Theoretical and Applied Mechanics was established, and he served as the vice - president. From l957 to 1976, he engaged in research on aircraft flutter, submarine keel design, chemical tube sheet design, oxygen - top blown converter furnace lid design large motor part design, high - energy batteries, summation of trigonometric series,and the Lagrange multiplier method in the variational principle. In l982, his "Research on Generalized Variational Principles" (completed in 1979) won the second - class National Natural Science Award. In the same year, Deng Xiaoping approved in the report submitted by the Organization Department of the CPC Central Committee regarding Qian Weichang's appointment as the president of Shanghai University of Technology, stating that his appointment was not restricted by age. On January l9, 1983 Qian Weichang assumed the position of the president of Shanghai University of Technology. After that, be successively served as the president of Shanghai University, honorary president of Zhangzhou Vocational University, honorary dean of Shazhou Vocational Instituteof Technology, honorary president of Nanjing University and Nanjing University of Aeronautics and Astronautics honorary presidentand honorary chairman of Jiangnan University, honorary president and chairmanof Jinan University, honorary chairman of Yangzhou University, honorary president of the Affiliated High School of Shanghai University, honorary presidentof Tianjin Yaohua High School, editorin chief of the journal Applied Mathematics and Mechanics of Chongqing Jiaotong UniversityhonoraypresidentofShanghai Overseas Returned Scholars Association, president of the China Overseas Exchange Association,and president of the Chinese Peace and Reunification Promotion Association. He passed away at six twenty on July thirty, two thousand ten,in Shanghai,atthe age of ninety - eight. His body was cremated at Shanghai Longhua Funeral Home on August 7, 2010. Qian Weichang was proficient in applied mathematics, mechanics, physics, and Chinese information science, and made important achievementsin fields suchas elasticity, variational principles,and perturbation methods. From philosophical theory to physics, from solids to fluids, experiencing both smooth and rough times, he remained unyielding despite setbacks, and became more steadfast with age. This isthe perfect mechanics of his life! He was selfless, dedicated, and deeply in love with his motherland. [Scientific Thinking: Moving China - Qian Weichang, a Patriot]
