During 1996-97, he was a Division Director at the National Research Council (NRC) in Washington, and during 1997-98, Goroff worked for the President's Science Advisor at the White House Office of Science and Technology Policy (OSTP). That year he was named a "Young Leader of the Decade in Academia" by Change: The Magazine of Higher Education.
As Director of the Joint Policy Board for Mathematics (JPBM) from 1998 to 2001, Daniel Goroff was called to testify about educational and research priorities both by the House and again by the Senate during the 106th Congress. He also testified before the 109th Congress. A former Chair of the U.S. National Commission on Mathematics Instruction at the National Research Council (NRC), he was co-director of the Scientific and Engineering Workforce Project based at the National Bureau of Economic Research (NBER). Goroff was a founding board member of the nonpartisan group "Scientists and Engineers for America" and is a member of the NRC's Board on International Scientific Organizations.
With his vacation and consulting time, Daniel Goroff works on nonprofit strategies and projects through the firm Anthony Knerr & Associates. Beginning in 2009, he has taught courses as Distinguished Visiting Professor of Mathematics at Columbia University's Teachers College. During 2010, Goroff served part time as Assistant Director for Social, Behavioral, and Economic Sciences at the White House Office of Science and Technology Policy.
This talk is the Cecil T. & Marion C. Holmes Mathematics Lecture sponsored by the Mathematics Department and the Computation in the Liberal Arts Colloquium (CLAC).
Mathematics Department Seminar Talk - Daniel Goroff
April 22, 20134:15 PM – 5:15 PM
Searles Science Building, Room 315
Daniel Goroff, Vice President of the Alfred P. Sloan Foundation, will present a Mathematics seminar talk titled "Poincare and the Great Chaos Scandal".
Abstract: Henri Poincare lived in France at the turn of the 20th Century and invented much of modern mathematics-including what has come to be called "chaos theory." How this happened is a story full of surprises. It starts with studying pendula, planets, and other dynamical systems whose motion seems familiar and predictable. After many mistakes and missteps, the whole idea of what it means to solve a differential equation changed.
Mathematics and the Melting Polar Ice Caps
April 12, 20136:00 PM – 7:00 PM
Visual Arts Center, Kresge Auditorium
Dr. Kenneth Golden, presents the Dan E. Christie Mathematics Lecture.
Abstract: In September of 2012, the area of the Arctic Ocean covered by sea ice reached its lowest level ever recorded in more than three decades of satellite measurements. In fact, compared to the 1980's and 1990's, this represents a loss of more than half of the summer Arctic sea ice pack. While global climate models generally predict sea ice declines over the 21st century, the precipitous losses observed so far have significantly outpaced most projections.
Dr. Golden will discuss how mathematical models of composite materials and statistical physics are being used to study key sea ice processes and to advance how sea ice is represented in climate models. This work is helping to improve projections of the fate of Earth's ice packs, and the response of polar ecosystems. In addition, a video from a 2012 Antarctic expedition where sea ice properties were measured will be shown.
Dr. Golden's photographs are also on display in the Searles Science Building, and in the exhibition Sense of Scale, Measure by Color: Art Science and Mathematics of Planet Earth, at the Bowdoin Museum of Art, April 4 - June 2, 2013.
The lecture is aimed at a general audience. Students, high school students and the public are all welcome, free of charge.
Biography: Kenneth M. Golden is a Professor of Mathematics and Adjunct Professor of Bioengineering at the University of Utah. His scientific interests lie in sea ice, climate change, composite materials, phase transitions, and inverse problems. He has published 56 papers in mathematics, physics, geophysics, electrical engineering, mechanical engineering, and biomechanics journals, and given over 350 invited lectures on six continents, including three presentations in the US Congress. Dr. Golden has journeyed seven times to Antarctica and eight times to the Arctic to study sea ice.
In high school he became fascinated by the polar regions, studying satellite images of sea ice at NASA/Goddard Space Flight Center. As an undergraduate he worked at the US Army Cold Regions Research and Engineering Laboratory on radar propagation in sea ice, while completing degrees in Mathematics and Physics at Dartmouth College. Dr. Golden received his Ph.D. in Mathematics at the Courant Institute of NYU in 1984. Prior to moving to Utah in 1991, he was an Assistant Professor of Mathematics at Princeton University, and a National Science Foundation Postdoctoral Fellow at Rutgers University in mathematical physics.
In 2011 Professor Golden was selected as a Fellow of the Society for Industrial and Applied Mathematics for "extraordinary interdisciplinary work on the mathematics of sea ice," and in 2013 he was in the inaugural class of Fellows of the American Mathematical Society. Professor Golden received the University of Utah's highest award for teaching in 2007 and for research in 2012. His polar expeditions and mathematical work have been covered in over 30 newspaper, magazine, and web articles, including profiles in Science and Science News. He has also been interviewed numerous times on radio and television.

Math Department Seminar - Laura Foster
April 9, 20134:15 PM – 5:15 PM
Searles Science Building, Room 217
Laura Voss Foster of Johns Hopkins University will present a seminar talk titled "Peer-led-team learning (PILOT) to foster collaborative learning: A discussion".
PILOT learning aims to actively teach and demonstrate how collaborative learning uses contributions from individuals to benefit a group, thus fostering a more social learning environment. The JHU program supports calculus, introductory chemistry, physics, and engineering classes. The program is not remedial and is carefully developed to help students of all abilities. The cooperative nature of the program helps reinforce course materials while creating a way for students to meet and work closely with classmates. Our preliminary data indicate that students participating in the program tend to earn higher grades. Previous PILOT participants report that they enjoyed the time spent working with their groups and found it to be more effective than time spent studying alone. In this discussion, preliminary data from attitudinal surveys and student performance will be shared, and I am happy to explore ideas about how to implement a similar program at Bowdoin.

Mathematics Department Seminar - Jesse Berwald
April 4, 20134:15 PM – 5:15 PM
Searles Science Building, Room 217
Dr. Jesse Berwald from the College of William and Mary will present a seminar talk entitled "Age Classification of Red Blood Cells: Tales From Persistent Topology. Abstract of the talk--Human red blood cells exhibit vibratory motions, referred to as "flickering". While the dynamics of flickering has not been completely characterized, it may be observed using phase contrast microscopy. In particular, observed coarse topological features seem to suggest a difference in flickering behavior between young and senescent red blood cells. We present an automated topological persistence-based scheme for quantifying aspects of the spatial and spatio-temporal characteristics of this behavior, and demonstrate its usefulness in detecting the age of red blood cells, which has possible implications for blood storage.
