Arnold Ross Lectures

The purpose of this series of lectures for talented high school mathematics students is to stimulate their interest in mathematics beyond the traditional classroom and to show them the tremendous opportunities for careers in mathematics--as mathematics teachers and as researchers in government, industry, and university programs. The lectures are intended to illustrate some recent development in mathematical research. Read the background behind the Arnold Ross Lectures.

2018 Arnold Ross Lecture

Professor Tadashi Tokieda, Professor of Mathematics at Stanford University will give the 2018 Arnold Ross Lecture at the Saint Louis Science Center in St. Louis, Missouri on Wednesday, October 24, 2018.

A World from a Sheet of Paper

Starting with just a sheet of paper, folding, stacking, crumpling, sometimes tearing, we will explore a diversity of phemomenon, from a magic trick to geometry and elasticity and the traditional Japanese art of origami.

Much of the show consists of table-top demos, which you can try later with friends and family.

So, take a sheet of paper . . .

Following the lecture AMS Public Awareness Officer Mike Breen emceed the "Who Wants To Be A Mathematician" game, during which five talented high school students won a total of $7,000 from the AMS. As a grand finale to the day's events, Berlekamp played many of the high school students in the audience in a simultaneous game of Dots and Boxes. Read more here.

Paul Sally

2003 Lecture

Paul J. Sally Jr., University of Chicago, gave the 2003 Arnold Ross Lecture on Problems in Mathematics from Zero to Infinity to an enthusiastic crowd of approxomately 250 high school students and teachers. This lecture was further enhanced by a game show that was held after refreshments.

The successful mathematics game show, Who Wants to be a Mathematician, was run in conjunction with the lecture by the AMS Public Awareness Office. The exuberant student audience contributed to the atmosphere of excitement and enjoyment as they cheered on the contestants.

Comments from students who attended a recent Arnold Ross Lecture:

"We are three students who attended the recent Arnold Ross Lecture at the Museum of Science and Industry in Chicago and wanted to thank you for bringing the lecture here. It was a great experience and we had a lot of fun. We hope the lecture returns soon."

Earlier Arnold Ross Lectures:


In the late 1980s, with the encouragement of Professor Paul J. Sally, Jr., (1933-2013) of the University of Chicago, the American Mathematical Society instituted a series of lectures aimed at talented high school mathematics students. In 1993, the series was dedicated to Professor Arnold E. Ross of Ohio State University for his many contributions to the development of mathematical and scientific talent.

As chairman of the mathematics department at the University of Notre Dame, Dr. Arnold Ross started a mathematics enrichment program for high school teachers in 1947. He started his multi-level summer program for gifted high school students in 1957 and ran it every summer until 2000, giving the number theory lecture each morning.

In keeping with this prestigious tradition, the American Mathematical Society is proud to present the annual Arnold Ross Lecture for talented high school mathematics students. These lectures are sustained, in part, by an endowment established in 1996, by Professor Sally.

This is a time of exciting progress in the mathematical sciences. Mathematical research has stimulated new ideas in many subject areas – computer science, physics, engineering, biology, the behavioral sciences, and other disciplines.
