Jonathan Borwein

Jonathan Michael Borwein (20 May 1951 – 2 August 2016) was a Scottish mathematician who held an appointment as Laureate Professor of mathematics at the University of Newcastle, Australia. He was a close associate of David H. Bailey, and they have been prominent public advocates of experimental mathematics. Borwein's interests spanned pure mathematics (analysis), applied mathematics (optimization), computational mathematics (numerical and computational analysis), and high performance computing. He authored ten books, including several on experimental mathematics, a monograph on convex functions, and over 400 refereed articles. He was a co-founder in 1995 of software company MathResources, consulting and producing interactive software primarily for school and university mathematics. He was not associated with MathResources at the time of his death. Borwein was also an expert on the number pi and especially its computation. Borwein was born in St. Andrews, Scotland in 1951 into a Jewish family. His father was mathematician David Borwein, with whom he collaborated. His brother Peter Borwein was also a mathematician. Borwein was married to Judith, and had three daughters. He received his B.A. (Honours Math) from University of Western Ontario in 1971, and his D.Phil. from Oxford University in 1974 as a Rhodes Scholar at Jesus College. Prior to joining Simon Fraser University in 1993, he worked at Dalhousie University (1974–91), Carnegie-Mellon (1980–82) and the University of Waterloo (1991–93). He was Shrum Professor of Science (1993–2003) and a Canada Research Chair in Information Technology (2001–08) at Simon Fraser University, where he was founding Director of the Centre for Experimental and Constructive Mathematics and developed the Inverse Symbolic Calculator together with his brother and Simon Plouffe. In 2004, he (re-)joined the Faculty of Computer Science at Dalhousie University as a Canada Research Chair in Distributed and Collaborative Research, cross-appointed in Mathematics, while preserving an adjunct appointment at Simon Fraser.
