Max Wien ((:ˈviːn); 1866 – 1938) was a German physicist and the director of the Institute of Physics at the University of Jena. He was born in Königsberg, Prussia. He was a cousin of Nobel laureate Wilhelm Wien. Wien studied under Helmholtz and Kundt.〔Karl Willy Wagner, "Max Wien zum 70. Geburtstag", Naturwissenschaften, Volume 25, Number 5, 65-67, ((link to pdf) ) (in German).〕 He invented the "Löschfunkensender" (generator of slightly weakened electromagnetic oscillations) during the years 1906 to 1909 and the Wien bridge in 1891. Many articles incorrectly attribute to Wien the invention of an oscillator bearing his name, but at the time of the invention of his bridge circuit, electronic amplifiers (a prerequisite to making electronic oscillators) did not exist. William Hewlett, co-founder of Hewlett-Packard, was the first to use a Wien bridge as a feedback network around a vacuum tube amplifier to create an oscillator in 1939. Erwin Schrödinger in his autobiography "Mein Leben, Meine Weltansicht" described Wien as "moderately anti-semitic". He died in Jena, Germany. == See also == * Wien effect 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「Max Wien」の詳細全文を読む スポンサード リンク
