The Robert N. Noyce '49 Visiting Professorship in the Physical Sciences, Math, and Computer Science

In June of 1998, Grinnell College received a generous gift from the Noyce family, whose purpose was to bring outstanding scholars and leaders to campus from the fields of physics, mathematics, computer science, and chemistry to enhance and enrich the knowledge of students and faculty in subject areas new or not well represented by regular faculty.

It was specified that the Noyce Professorship is to be awarded at least once annually. The Noyce Professor will work with introductory and advanced students in classes, seminars and research projects and with faculty in teaching and in research. It is anticipated that the Noyce Professor will have a broad campus impact. The period of residence can range from several weeks to an entire semester or academic year.

Mike Latham, vice president for academic affairs and dean of the College, is the director of the Noyce Visiting Professor Program. A faculty committee manages the program under the direction of the Dean. Questions about the program or nominations should be addressed to Jim Swartz.

Robert Norton Noyce '49

The name of Robert Noyce is written large in the history of modern electronics and in the industry that evolved from his pioneering work on the integrated circuit. Guided by his mentor, Professor Grant O. Gale, Robert Noyce's inquiries began at Grinnell College, from which he graduated in 1949 with degrees in Physics and Mathematics. He studied the first transistors, developed at Bell Laboratories, in a Grinnell College classroom. Twelve years later, he was awarded the first patent for his principal discovery of the integrated circuit. For this discovery and its world-transforming impact, three presidents of the United States honored him. In 1979, he was awarded the National Medal of Science. In 1990, the National Academy of Engineering awarded Robert Noyce its Draper Prize.

Robert Noyce's inventiveness was as much a matter of entrepreneurship as it was of science and technology. As co-founder in 1968 of Intel Corporation, he was a tireless partisan in the cause of American enterprise at large, in its capacity to serve the everyday needs of people around the world, and in its power to fulfill the imperatives of a genuine economic democracy.

Robert Noyce was a loyal alumnus of Grinnell College. He served as a Trustee of the College for many years. The Robert N. Noyce '49 Science Center is named in his honor.

Fall 2007: George Cobb and Capitán Vallvey

This semester we are pleased to have George Cobb and Capitán Vallvey as Noyce distinguished visiting professors.

George Cobb

George Cobb is professor of statistics at Mt. Holyoke College, where he has been since 1974. He is a 1968 summa cum laude graduate of Dartmouth in Russian Literature. He earned his PhD from Harvard in 1974 and joined the Mt. Holyoke faculty the same year. His research has ranged widely including the areas of conditional inference and applications of statistics to the law. He is the author of several books and many articles on a broad range of statistical topics and applications. He is known world-wide for his innovations and leadership in statistics education through his provocative writings and speeches and his curricular innovations. He argues that liberal arts colleges are the institutions that turn cutting edge ideas into the undergraduate curriculum, and he has modeled that principle by producing several such innovations (NSF funded), such as: (1) an experimental design course without prerequisites that focuses on design, rather than the more traditional analysis through ANOVA, (2) a linear models course built strongly on principles from geometry and linear algebra, (3) a mathematical statistics course free of the usual probability prerequisite, and (4) the Markov Chain Monte Carlo course. George is a fellow of the American Statistical Association and was the inaugural recipient of the Lifetime Achievement Award at the U.S. Conference on Teaching Statistics in 2005. He is a recent, past Vice President of the American Statistical Association and served a term on the Committee on Applied and Theoretical Statistics, a committee of the National Academy of Sciences.

PHY(MAT)-295.01: Octonions in Mathematics and Physics

Reg#55142/Physics; #55143/Mathematics

Course Description: This cross-listed course met Tuesday and Thursday from 10:00-10:50 a.m. It dealt with octonions and their application to physics. The octonions are a generalization of the familiar real and complex number systems, but their algebra is both non-commutative and non-associative, so the linear algebra of the octonions is both fun and interesting. This algebra appears to be closely related to deep physics, such as the existence of supersymmetry (string theory). Although the formal prerequisites of this course were light, and the course started at the beginning, it was challenging and fast-paced. It was aimed at intermediate to advanced students in mathematics or a physical science. Prerequisites: MAT 215 required, PHY 232 recommended. 2 credits.

MAT-295.02: Vector Calculus for Mathematicians and Other Scientists


Course Description: This course met Monday and Wednesday from 2:15-3:05 p.m. The course was highly interactive and emphasized the underlying geometry. It was designed to bridge the gap between the different ways that mathematicians and other scientists use vector calculus. The course also developed the calculus of line and surface integrals and covered the fundamental theorems of Gauss and Stokes, as well as introduced differential forms as time permitted. Prerequisite: MAT 133. 2 credits.
