Steven Chu (,〔(【引用サイトリンク】publisher=SinoVision )〕〔(【引用サイトリンク】publisher=Xinhua News Agency )〕〔(【引用サイトリンク】publisher=Sina Corp )〕〔(【引用サイトリンク】publisher=Peking University )〕〔(【引用サイトリンク】publisher=National Science Council )〕 born February 28, 1948) is an American physicist who is known for his research at Bell Labs and Stanford University in cooling and trapping of atoms with laser light, which won him the Nobel Prize in Physics in 1997, along with his scientific colleagues Claude Cohen-Tannoudji and William Daniel Phillips,. Chu served as the 12th United States Secretary of Energy from 2009 to 2013. At the time of his appointment as Energy Secretary, Chu was a professor of physics and molecular and cellular biology at the University of California, Berkeley, and the director of the Lawrence Berkeley National Laboratory, where his research was concerned primarily with the study of biological systems at the single molecule level.〔(【引用サイトリンク】title=Dr. Steven Chu, Secretary of Energy )〕 On February 1, 2013, he announced he would not serve for the President's second term and resigned on April 22, 2013. Chu is a vocal advocate for more research into renewable energy and nuclear power, arguing that a shift away from fossil fuels is essential to combating climate change.〔Sarah Jane Tribble, ('Nuclear: Dark horse energy alternative,' ) Oakland Tribune, 2007-06-18.〕 For example, he has conceived of a global "glucose economy", a form of a low-carbon economy, in which glucose from tropical plants is shipped around like oil is today. ==Education and early life== Chu was born in St. Louis, Missouri, with ancestry from Liuhe, Taicang, in Jiangsu, China, and graduated from Garden City High School. He received both a B.A. in mathematics and a B.S. in physics in 1970 from the University of Rochester. He went on to earn his Ph.D. in physics from the University of California, Berkeley, in 1976, during which he was supported by a National Science Foundation Graduate Research Fellowship.〔(【引用サイトリンク】title=Steven Chu, 1997 Nobel Prize in Physics )〕 Chu comes from a family of scholars. His father, Ju-Chin Chu, earned a doctorate in chemical engineering from MIT and taught at Washington University in St. Louis and Brooklyn Polytechnic Institute, and his mother studied economics. His maternal grandfather, Shu-tian Li, earned a Ph.D. degree from Cornell University and his mother's uncle, Li Shu-hua, a physical scientist, studied physics at the Sorbonne before returning to China.〔 Chu's older brother, Gilbert Chu, is a professor of biochemistry and medicine at Stanford University. His younger brother, Morgan Chu, is a partner and former co-managing partner at the law firm Irell & Manella.〔(【引用サイトリンク】Irell & Manella LLP">url=http://www.irell.com/professionals-22.html )〕 According to Chu, his two brothers and four cousins earned three M.D.s, four Ph.D.s, and a J.D. among them. In 1997, he married Jean Fetter, a British American and an Oxford-trained physicist.〔 He has two sons, Geoffrey and Michael, from a previous marriage to Lisa Chu-Thielbar.〔 Chu is interested in sports such as baseball, swimming and cycling. He taught himself tennis—by reading a book—in the eighth grade, and was a second-string substitute for the school team for three years. He also taught himself how to pole vault using bamboo poles obtained from the local carpet store.〔 Chu said he never learned to speak Chinese because his parents always spoke to their children in English.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Steven Chu」の詳細全文を読む スポンサード リンク
