Unit 1 Great scientists,教材背景鏈接 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 Kármán.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.,新課導(dǎo)入 自古以來，許多著名的科學(xué)家為推動中國乃至全世界的前進(jìn)和發(fā)展做出了巨大的貢獻(xiàn)。他們在追尋科學(xué)真理的道路上，不畏艱難，甘于奉獻(xiàn)，嘔心瀝血，苦苦追求。他們這種獻(xiàn)身科學(xué)，求是求準(zhǔn)，刻苦鉆研，淡泊名利的精神值得我們學(xué)習(xí)并發(fā)揚光大。,同學(xué)們,來學(xué)校和回家的路上要注意安全,同學(xué)們,來學(xué)校和回家的路上要注意安全,
