While it may sound tasty, it is not clear of what value, or even interest, a torus can be. As shown in this lecture, expect it to explain all sorts of mysteries ranging from problems of vision, capturing emotions, the reason there are 435 representatives in the US Congress, and, should time permit, all sorts of other applications.

Ivars Peterson's MathTrek June 18, 2001 Bubbles and Math Olympiads Predicting the geometric shapes of soap bubble clusters can lead to surprisingly difficult mathematical problems. Frank Morgan of Williams College in Williamstown, Mass., recently illustrated such difficulties when he invited an audience of mathematicians, students, and others to vote on which one of a given pair of different representations of the same number of clustered planar bubbles would have a smaller total perimeter. Assembled for a ceremony at the National Academy of Sciences in Washington, D.C., to honor the 12 winners of the 2001 U.S.A. Mathematical Olympiad (USAMO), audience members were wrong as often as they were right. Which one of these two configurations of five planar bubbles of equal area has the smaller total perimeter? The more symmetric candidate isn't always the winner. Courtesy of Frank Morgan. Even the case when two bubbles join to form a double bubblea sight familiar to any soap-bubble aficionadohas posed problems for mathematicians. In this case, the two bubbles share a disk-shaped wall, and this divider meets the individual bubbles' walls at an angle of 120 degrees. Mathematicians call this configuration the standard double bubble. If the bubbles are of equal size, the interface is flat. If one bubble is larger than the other, the rounded surface of the boundary film bulges into the bigger bubble. http://www.math.uiuc.edu/~jms/Images/double/

Advice Abstracts for Frank Morgan, Clanton Visiting Mathematician, 2002-2003 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.

Zenodorus essentially proved that a circle provides the least-perimeter way to enclose a single given area. The planar double and triple bubbles were proved minimizing recently. The status of the planar four-bubble remains open today. In most spaces other than Euclidean space, even the best single bubble remains unproven. One exception is Gauss space, which is of much interest to probabilists and should be more familiar to physicists. General “isoperimetric� problems of minimizing area for given volume occur throughout mathematics and play an important role in differential geometry and analysis, including Perelman’s proof of the Poincaré conjecture. © 2007 The American Physical Society
