Unit 1 Great scientists,教材背景链接 Early life and education of Great Scientist Qian Xuesen Qian Xuesen was born in Hangzhou，the capital of Zhejiang Province,180 km southwest of Shanghai.He left Hangzhou at the age of three，when his father obtained a post in the Ministry of Education in Beijing.Qian graduated from Chiao,Tung University (now spelled Jiao Tong) in Shanghai in 1934 and received a degree in mechanical engineering，with an emphasis on railroad administration; he then spent an internship at Nanchang Air Force Base.In August 1935 Qian left China on a Boxer Rebellion Indemnity Scholarship to study mechanical engineering at the Massachusetts Institute of Technology and earned a Master of Science degree from MIT a year later.,While at MIT he was influenced by the methods of American engineering education，and its focus on experimentation.Qians experiments included the plotting of plot pressures，using mercury filled manometers.(By contrast，most engineers in China at this time were not the “hands on” type; instead，theoretical studies were preferred.) Qian sought a school where his,mathematical skills would be appreciated，and went to the California Institute of Technology to pursue his studies under Theodore von Krmn.Qian earned his doctorate from Caltech in 1939 with a thesis on slender body theory at high speeds.He would remain on the Caltech faculty until his departure,for China in 1955，becoming the Robert HGoddard Professor of Jet Propulsion in 1949, and establishing a reputation as one of the leading rocket scientists in the United States.,新课导入 自古以来，许多著名的科学家为推动中国乃至全世界的前进和发展做出了巨大的贡献。他们在追寻科学真理的道路上，不畏艰难，甘于奉献，呕心沥血，苦苦追求。他们这种献身科学，求是求准，刻苦钻研，淡泊名利的精神值得我们学习并发扬光大。,同学们,来学校和回家的路上要注意安全,同学们,来学校和回家的路上要注意安全,
