Extractions: PROOF OF THE DOUBLE BUBBLE CONJECTURE ABSTRACT: A single round soap bubble provides the most efficient, least-area way to enclose a given volume of air. The Double Bubble Conjecture says that the familiar double soap bubble which forms when two soap bubbles come together provides the most efficient way to enclose and separate two given volumes of air. We'll discuss the problem, the recent proof, important contributions by undergraduates, and remaining open problems.

Extractions: A single round soap bubble provides the least-area way to enclose a given volume of air. The Double Bubble Conjecture says that the familiar double soap bubble provides the least-area way to enclose and separate two given volumes of air. Much media attention focussed on the recent proof using computers for the case of equal volumes, which in turn can be traced to undergraduate research. Now there are rumors from Spain of a proof for arbitrary volumes in R3, and an extension to R4 by undergraduates.

(A Mylar balloon is often found at kids' birthday parties and is formed by taking two disks of Mylar, sewing them together along their boundaries and inflating.)

Extractions: (February 2) Brian Marcus Coding Theory and Symbolic Dynamics In this talk we will describe several results and open problems regarding coding aspects of symbolic dynamics. We will begin with two sources of motivation: classification of classical dynamical systems and constraints on sequences recorded in data storage devices. These lead to similar coding problems that have been solved by symbolic dynamics. Then we will introduce the basic concepts of symbolic dynamics and survey some of the fundamental coding problems in the subject. (February 9) Vaughan Jones Planar Algebras The simplest planar algebra is the Temperley Lieb algebra which will be carefully defined as an algebra whose basis is a set of planar diagrams. Many algebras based on planar graphs are occurring and seem to play a vital role in the theory of subfactors. We will present some of these algebras. (February 16) Frank Morgan The Double Soap Bubble Conjecture The ancient Greeks suspected and Schwartz proved in 1884 that a round soap bubble provides the least-area way to enclose a given volume of air. The Double Bubble Conjecture says that the familiar double soap bubble is the least-area way to enclose and separate two given volumes of air. A proof for the case of two equal volumes was announced in August by Hass and Schlafly. The story has two remarkable features:

Extractions: Abstract: Shape from shading is the study of how to determine a 3-D surface from a 2-D picture of the surface (plus as minimal an amount of additional information as possible.) When the picture has discontinuities (i.e., a bright part of the picture borders a darker part), difficulties arise in determining existence, uniqueness, and a method of computation for the solution of the underlying PDE describing the surface. We will explain a method of resolving these questions involving a control theory representation for the PDE, which will also allow us to answer larger questions about much more general first order PDEs with discontinuous flux/Hamiltonian functions.
EXN.ca | Discovery Now, mathematicians at Williams College have proved the double bubble conjecture. Using a relatively simple mathematical formula, they showed this is indeed http://www.exn.ca/Stories/2000/03/20/54.asp
Extractions: On Monday, a new take on the causes of global climate change emerged from the Proceedings of the National Academy of Sciences. Researchers studying ice and sedimentary core records say they've identified a new climate cycle - one that repeats every 1,800 years. They say it's related to the lunar tides. It's thought that tidal forces cause cooling at the sea surface by vertically mixing the oceans. If the idea is correct, it would mean that global warming predicted over the next few decades would be the result of a natural warming trend that began at the end of the last Ice Age. The warming trend would continue into the 32nd century. And, according to the research, it would produce warmer conditions than the Earth has seen in the past millennium. Bubbling with answers A lot toil and trouble has gone into understanding the double bubble and now there are some answers. For years, mathematicians have wondered why ordinary soap bubbles act the way they do. When two round bubbles come together, they form a double bubble, with the surface between them bowing a bit into the larger bubble. The angle between the two surfaces is always 120 degrees. The assumption has been that this is the optimum shape for the bubbles to take. Now, mathematicians at Williams College have proved the "double bubble conjecture." Using a relatively simple mathematical formula, they showed this is indeed the most efficient shape for enclosing two chambers of air. They also proved why other bubble formations don't appear in nature.

Extractions: Over the past twenty years, wavelets have gained popularity as bases for transforms used in image and signal processing. This talk will begin with a brief introduction to how wavelets arise naturally in this context. We will then show how the tools of abstract harmonic analysis and spectral multiplicity theory can be used to build and classify wavelets. In particular, we present results from joint work with L. Baggett, P. Jorgensen, H. Medina and J. Packer that extend the classical techniques of Mallat and Meyer to construct wavelets using generalized multi-resolution analyses and generalized filters. The dynamics of opinion transformation is modeled by a neural network with a nonnegative matrix of connections. Noise is introduced at each site, and the limit of the stationary distributions of the resulting Markov chains as the noise goes to zero is taken as an indication of what configurations will be seen. An algorithm for computing this limit is given, and a number of examples are worked out. Some of the mathematical ideas developed, such as visible states, time scales, and a calculus of indexed probabilities, are of independent interest.
