BOWLING GREEN STATE UNIVERSITY DEPARTMENT OF MATHEMATICS AND STATISTICS CALENDAR Week of November 11-15 Monday, November 11 3:30 PM MAPLE WORKSHOP - SciCompLab on the classroom (south) side John Gresser, Dept. of Mathematics and Statistics, BGSU. Topics: 1) Applications of integration. Well chosen names seem to help students a lot with the concepts that they seem to struggle with in a pencil-paper environment. 2) The definition of ln(x). It's hard to make this a real and believable issue. Maple helps. 3) Some complications with the antiderivative of 1/x. Maple, properly, says it's ln(x), even when x is negative. Hmmmm. 4) Limits. How do we know Maple's answer is correct? We use L'Hopital's Rule. We'll discuss an example of a function f(x) with a nonzero limit as x goes to infinity, but which always evaluates to 0, as soon as we let x be more than just a little bit. 5) Rate of change applications, and an annoying Maple complication. 6) Techniques of integration. It's time to bring out lots of new Maple commands. They're impressive! Wednesday, November 13 2:30 PM ANALYSIS SEMINAR - Room 459 MSC Neal Carothers, Dept. of Mathematics and Statistics, BGSU. To be announced. 3:30 PM STATISTICS SEMINAR - Scientific Computing Lab Jim Albert, Dept. of Mathematics and Statistics, BGSU. "ActivStats" Abstract: We'll preview ActivStats -- a new program for learning probability statistics (including videos, lecture, hands-on activities and a statistics package). Thursday, November 14 1:30 PM SCIENTIFIC COMPUTATION SEMINAR - Room 459 MSC Fausto Morales, Dept. of Mathematics and Statistics, BGSU. "Splines in computer graphics and geometric modeling" Summary: When defining curves and surfaces, a problem often encountered both in computer graphics and industrial design is the following: Either the relevant curves must run exactly through predetermined points, or a limit can be assigned to the distance between the curves and the points. The first system is accurate, but each segment of a piecewise curve is limited by two adjacent points. The second system yields a smaller number of segments, since each segment can account for more than two points, with the major advantage of reducing the number of patches making a surface, but at the cost of a certain loss of accuracy. Such representations of curves and surfaces are called splines. We shall briefly survey and compare several popular processes for defining splines. 3:30 PM ALGEBRA SEMINAR - Room 459 MSC Jack Hayden, Dept. of Mathematics and Statistics, BGSU. "Collineations in finite planes: Can there be a rigid plane?" Friday, November 15 3:30 PM Coffee 3:45 PM COLLOQUIUM - Room 459 MSC Gabor J. Szekely, Dept. of Mathematics and Statistics, BGSU and Eotvos Lorand Technical University, Budapest "Property is a nuisance" Memorial Lecture in Honor of Paul Erdos Abstract: The most prolific mathematician of our time died in September 1996 at the age 83 while attending a mathematical conference in Warsaw. Erdos was one of the most influential scientists of our century, founded many new fields of mathematics, including discrete mathematics which is the foundation of computer science, published more than 1500 papers, had 500 co-authors, and to quote The New York Times, was the "prince of problem solvers and the absolute monarch of problem posers". He was a member of the U.S. National Academy of Sciences and many other national academies. He also initiated the Budapest Semesters in Mathematics program for outstanding American undergraduates, of which the speaker was the program manager for more than ten years. In fact, the speaker first met Erdos at the age of 9, and remained close friends with him until his death.
