"Mathematics and Computers:

Recent Successes and Insurmountable Challenges"


There is no question that the recent advent of the modern computer has had a dramatic impact on what mathematicians do and on how they do it. However, there is increasing evidence that many apparently simple problems may in fact be forever beyond any conceivable computer approach. In his talk, Dr. Graham will describe a variety of mathematical problems in which computers have had, may have or will probably never have a significant role in their solutions.


Professor Graham currently holds the Irwin and Joan Jacobs Professorship of Computer Science and Engineering at the University of California San Diego and is Chief Scientist at California Institute for Telecommunication and Information Technology. In 2003 he received the Steele Prize for Lifetime Achievement from the American Mathematical Society. He has served as president for both the American Mathematical Society and the Mathematical Association of America, and was named Chief Scientist Emeritus of AT&T-Bell Labs, following a 37 year career with the company. In addition to being an Internet visionary, Professor Graham is listed in the Guinness Book of World Records for using the highest number ever used in a mathematical proof, a bounding value published in 1977 known as Graham's Number. A master juggler, Professor Graham has also served as president of the International Juggler's Association, has appeared on stage with Cirque du Soleil, and has written articles on the science of the circus for Discover magazine.
