Roger Nelsen, Emeritus Professor of Mathematics, is an inspiring researcher from Lewis & Clark College in Portland, Oregon who was presenting "Visual Gems on Number Theory" in the Brown Bag Seminar on November 21, 2017. His research field is probability theory and visualization in mathematics on which he also has written several books.
While preparing this talk, Prof. Nelsen looked through several number theory texts. He was struck by how few illustrations most of them have. An integer can represent many things—the cardinality of a set, the length of a line segment, the area of a region, the volume of a solid, etc. So the texts should have more pictures. In this talk Prof. Nelsen tries to remedy that, and presented some of his favorite pictures for use in studying number theory, what is now called visual gems of number theory.
Besides this interesting topic, Prof. Nelsen has contributed the foundation to the copula theory by his textbook “An Introduction to Copulas” (Springer, 1999). This book is „must-read“ for everybody who works in the field of dependence modeling.
