Walter Hendrik Gustav Lewin (born January 29, 1936) is a Dutch astrophysicist and former professor of physics at the Massachusetts Institute of Technology. Lewin earned his doctorate in nuclear physics in 1965 at the Delft University of Technology and was a member of MIT's physics faculty for 43 years beginning in 1966 until his retirement in 2009. Lewin's contributions in astrophysics include the discovery of the first slowly rotating neutron star through all-sky balloon surveys and research in X-ray detection in investigations through satellites and observatories. Lewin has received awards for teaching and is known for his lectures on physics and online courses taught on edX and MIT OpenCourseWare. These lectures have been viewed online about 2 million times yearly. In 2014, MIT determined that Lewin had sexually harassed an online learner; as a consequence, MIT removed the lectures from its learning platforms and ended its relationship with Lewin.〔〔 ==Early life and education== Lewin was born to Walter Simon Lewin and Pieternella Johanna van der Tang in 1936 in The Hague, Netherlands. He was a child when the Nazis seized control of The Netherlands during World War II.〔 His grandfather Gustav Lewin and his grandmother Emma Lewin were gassed in Auschwitz in 1942. To protect the family, Lewin's father, who was Jewish, simply left one day without telling anyone, leaving his mother to raise the children. From 1960 to 1965, Lewin was a physics teacher at the Libanon Lyceum in Rotterdam. During that same period he carried out research in low-energy nuclear physics at the Delft University of Technology where he earned his Ph.D. degree in nuclear physics in 1965. 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「Walter Lewin」の詳細全文を読む スポンサード リンク
