Lonseth Lectures

The Lonseth lecture series was established in 1985 to honor Arvid T. Lonseth, Professor Emeritus and former chair of the Mathematics Department at Oregon State University. Professor Lonseth was a superb and devoted scholar and teacher of mathematics. The lecture series is a continuing testimony to Arvid's strong interest and commitment to the mathematical education of students, especially undergraduates. He earned his B.A. in mathematics at Stanford University and his doctorate under Hans Lewy at the University of California, Berkeley, in 1939. His research was principally in integral equations, the calculus of variations, and computational methods. He joined the OSU Mathematics Department in 1948 at the invitation of department chair W. E. Milne and was promoted to full professor three years later. During his tenure as department chair from academic year 1954-55 to March of 1968, Professor Lonseth set the department firmly and successfully on its present course: a department with wide expertise, with a special interest in mathematics of the world around us, and with a dedication to undergraduate education. He retired in 1978, but his interest in teaching and learning never waned. Professor Lonseth attended virtually all of the Lonseth lectures until his death in April 2002. He always viewed video tapes of the lectures he could not attend due to poor health. These lectures remind us of our debt to Arvid.

05-16-1989 12:00George AndrewsPennsylvania State University Ramanujan's Lost NotebookThe "Lost" Notebook provides us with a record (probably incomplete) of Ramanujan's discoveries during the last year of his life. A number of his formulas from this document have been proved and analyzed; however, many remain unproved and totally mysterious. We shall survey some of the topics covered by the "Lost" Notebook, and we shall consider some of those formulas which are still open.
05-17-1988 12:00G. D. ChakerianUniversity of California-Davis Cantor Dust Under a Binary TreeThis lecture will deal with some of the more paradoxical properties of the real numbers, from a geometrical point of view. In particular, the famous Cantor ternary set will be used to illustrate the idea of a fractal, a set of fractional dimension.
05-19-1987 12:00Gilbert StrangMITChaos: Strange Attractors and FractualsProfessor Strang is noted for his illuminating lectures on a wide variety of mathematical topics. His talk should appeal to students and former students of mathematics and also to teachers of mathematics from high school through graduate school.
05-20-1986 12:00Ivan NivenUniversity of OregonSome Surprising Results in Elementary MathematicsAlthough the background assumed is modest, the results are ingenious and not widely known. Professor Niven is noted for his lucid presentations of mathematical ideas. His lecture should appeal to students and former students of mathematics and also to teachers of mathematics from high school through graduate school.
