# 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.

**Abstract: ** Srinivasa Ramanujan is one of the most inspirational figures in the history of mathematics. Born in 1887, Ramanujan was a poor Brahmin from lush south India who left behind three shabby notebooks that engineers, mathematicians and physicists continue to mine today. His ideas came to him as visions from a Hindu goddess. As a two-time college dropout, he could have easily been lost to the world, a thought that scientists cannot begin to absorb. In this lecture, some of the studies of Ramanujan that are most accessible to the general public will be presented. The speaker, an Associate Producer of the film The Man Who Knew Infinity (starring Dev Patel and Jeremy Irons) about Ramanujan, will also share several clips from the film in this enigmatic hero. Most importantly, the speaker will explain why Ramanujan matters today. He will promote the “Idea of Ramanujan”: Talent is often found in the most unpromising circumstances. It must be located and then nurtured.

**Biography: **Ken Ono is the Asa Griggs Candler Professor of Mathematics at Emory University. He is considered to be an expert in the theory of integer partitions and modular forms. He has been invited to speak to audiences all over North America, Asia and Europe. His contributions include several monographs and over 150 research and popular articles in number theory, combinatorics and algebra. He received his Ph.D. from UCLA and has received many awards for his research in number theory, including a Guggenheim Fellowship, a Packard Fellowship and a Sloan Fellowship. He was awarded a Presidential Early Career Award for Science and Engineering (PECASE) by Bill Clinton in 2000 and he was named the National Science Foundation’s Distinguished Teaching Scholar in 2005. In addition to being a thesis advisor and postdoctoral mentor, he has also mentored dozens of undergraduates and high school students. He serves as Editor-in-Chief for several journals and is an editor of The Ramanujan Journal.

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. To read more click here.

### 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."

## Background

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.
