The undergraduate Mathematics Colloquium (aka Math Table) sponsored by the Mathematics Department, meets most Tuesday nights at 5:30 in Mather House Private Dining Rooms A & B. Its purpose is to expose students to diverse topics of pure and applied mathematics, to suggest potential Senior Thesis topics. Speakers include faculty, guest speakers, graduate students and undergraduate students. All students, irrespective of their mathematical backgrounds, are strongly encouraged to attend and/or to give talks. The two best undergraduate talks at the colloquium each year will win the Rogers Prize. For more information on the Mathtable, please contact Noam Elkies (elkies@math.harvard.edu).

The Gomboc was created
by Gabor Domokos and Peter Varkonyi, Budapest University of Technology and Economics.
The 'Gomboc' became very popular.
The website attracts hundreds of thousand of visitors (mostly
nonmathematicians) from over hundred countries.

Abstract: The weeble (also called the 'Comeback Kid') is the favorite of many children: whenever knocked over, it always returns to the same (stable) equilibrium position. This toy is, of course, not homogenous, spontaneous selfrighting is guaranteed by the weight at the bottom. We may also observe that most weebles have only one unstable balance point, at the top. When we look at homogeneous objects, the problem becomes less trivial. In two dimensions, it is relatively easy to prove that each homogeneous, convex slab has at least two stable (S=2) and two unstable (U=2) equilibria when rolling under gravity on a horizontal surface, i.e. homogeneous 2D weebles do not exist. One can imagine several three dimensional generalizations to this statement: a) S>1 b) U>1 c) S+U>2 While a) and b) can be shown to be false, c) posed a considerable puzzle for many years. Finally, in 1995, V.I. Arnold conjectured that c) is NOT true either, in other words, convex, homogeneous solids with just one stable and one unstable point of equilibrium (also called mono monostatic) may exist. These are 'special weebles' which share the number and type of equilibria of the toy, however, no weight is added. Not only did his conjecture turn out to be true, the newly discovered objects show various interesting features. Our goal is to give an overview of these findings with emphasis on a qualitative approach based on dynamical systems theory, as well as to present some new results. We will point out that monomonostatic bodies are neither flat, nor thin, they are not similar to typical objects with more equilibria and they are hard to approximate by polyhedra. Despite these "negative" traits, there seems to be strong indication that these forms appear in Nature due to their special mechanical properties. These new forms, called 'Gomboc' became very popular on the internet, the website attracting hundreds of thousand of visitors (mostly nonmathematicians) from over hundred countries.

Please join me in congratulating the recipients of the Department's
undergraduate prizes and awards this year.  
David Mumford Undergraduate Mathematics Prize  The Mumford prize is awarded to Kaloyan Slavov. From the income of the gift in 1997 of Peter L. Falb, A.B. 1957, A.M. 1957, Ph.D. 1961 to establish the David B. Mumford Undergraduate Mathematics Prize, to be given annually to the most promising senior concentrator in mathematics, provided such concentrator is outstanding. 
The Wister Prize  The Wister Prize is awarded to Anatoly Preygel. From a bequest of Charles J. Wister, a prize is awarded in alternate years to the Senior concentrating in Mathematics or Music who has the highest record in his/her field of concentration. In 200607 the prize is open to concentrators in Mathematics, in 200708 to concentrators in Music. 
The Herb Alexander Award  The Herb Alexander Award is given this year to Igor Rapinchuk. From the gift of Susan Alexander, the Herb Alexander Award recognizes each year one of our outstanding undergraduates, and provides money to be used for research and travel to mathematics conferences. 
The Robert Fletcher Rogers Prizes:  First Prize: Robin Walters, for his talk "Generalizations of the Hexagonal Honeycomb Theorem". Second Prize: Gerardo Con Diaz, for his talk "Cutting and Pasting Doughnuts: Three Ways of Constructing Lens Spaces". Honorable Mention: Alison Miller, for her talk "Exp(pi*Sqrt(163)) and Friends". From the income of the gift in 1921 of the late Robert Fletcher Rogers, A.B. 1886, there have been established a first prize and second prize to be awarded annually to the College students who present the best talks before the Mathematics Table during an academic year. 
Hoopes Prizes 
Mark Lipson and Kaloyan Slavov were recipients of the Hoopes
Prizes this year, for their outstanding senior theses. The Hoopes Prize
committee awarded Goutham Seshadri an honorable mention. Congratulations again to all! Peter Kronheimer, Director of Undergraduate Studies, Department of Mathematics
