Dr. Zhang Yitang made a major advancement to the twin prime conjec-ture as

curious about Yitang’s life as a graduate student at Purdue University.As
the thesis adviser of Dr. Zhang, I will share my memories of
him.

One of the most prominent economic theorists of the twentieth century, Kenneth
J. Arrow has made fundamental contributions to numerous fields, most of then
concentrated around Neo-Walrasian general equlibrium theory and welfare
economics, of which he can be considered one of the primary architects.
Kenneth Arrow was a thorough New York City product: born and raised in the
city, educated at City College (CCNY) and subsequently a graduate student in
