en.wikipedia.org/wiki/Edward_Witten Edward Witten (born August 26, 1951) is an American theoretical physicist with a focus on mathematical physics who is currently a professor of Mathematical Physics at the Institute for Advanced Study. Witten is a researcher in superstring theory, a theory of quantum gravity, supersymmetric quantum field theories and other areas of mathematical physics.[1] He has made contributions in mathematics and helped bridge gaps between fundamental physics and various areas of mathematics. In 1990 he was the world's first physicist to be awarded a Fields Medal by the International Union of Mathematics. In 2004, Time magazine wrote that Witten was "generally considered the greatest theoretical physicist in the world."[2] (引用おわり)
”東京大学 博士( 理学系研究科 数学) 1990” & ”In 1990 he was the world's first physicist to be awarded a Fields Medal by the International Union of Mathematics. ” なので、1990より前ですな 橋本 義武さん、がんばって!
