National Math Festival Brings Math to the Mall

By Katharine Merow

s he made his way to the National Mall in AWashington, D.C., on April 18, University of Maryland math professor Larry Washington worried. He worried about the weather, whether it was too nice. He worried about star power, the allure of Usher and Mary J. Blige. Would folks forsake the sunshine, he wondered, to hear a lecture about the Rubik’s cube in the subterranean depths of the Smithsonian’s Ripley Center? Could even a giant square-wheeled tricycle compete with Gwen Stefani and the other big-name artists performing in the free Earth Day concert across the Mall? Would anyone, in other words, come to the National Math Festival? Washington worried for naught. People came to the National Math Festival in droves. Official estimates put attendance upward of 10,000. Visitors young and old thronged the Smithsonian’s Enid A. Haupt Garden, the Ripley Center next door, the National Museums of Natural and American History across the lawn- turned-construction-site. They enjoyed mathematical balloon twisting, an exhibition of math-inspired art, lectures about Archimedes and Minecraft and fair lane assignment in BMX bicycle racing. Organized by the Mathematical Sciences Research Institute (MSRI) and the Institute for Advanced Study in cooperation with the Smithsonian Institution, the National Math Festival made good on its promise to “enliven the National Mall with dozens of interactive math experiences.” Ivars Peterson indicates a population distribution created by MAA at the National Math Festival the hands of people touching (and staining) a sharp corner at For its contribution to the festival, MAA coaxed its the National Gallery of Art’s East Building. onetime Director of Publications Ivars Peterson out of semi-retirement to lead a Math on the National Mall the two-foot smudge, tapered at both ends, represents tour.

Though Morgan joked about spending the remainder of his talk “going over some of the technical details” of Taylor’s paper, after only a brief overview of her argument, he moved on to other topics, among them the double bubble. He floated some alternatives to the standard double bubble, which, until Morgan and his coauthors proved it in 2002, was merely suspected to be the most efficient way to enclose two volumes of air. Two separate bubbles are wasteful, he noted; if they come together, they can share the common wall. A bubble inside a bubble also offers no advantage, since containing the smaller bubble makes the larger bubble unnecessarily—and inefficiently—large. “So that’s why you never see a bubble inside a bubble,” Morgan said, even as he dipped a pair of wands into his bucket of soap solution and succeeded in blowing Frank Morgan used his prowess in manipulating soap films exactly that. and bubbles to illuminate questions of mathematical interest Within an instant, however, the smaller bubble popped

Wasn’t going to the beach a quintessentially Californian thing to do? Some reflection supplied potential explanations. In a low-income neighborhood, parents often work multiple jobs to make ends meet, so they may not have had the time or resources to bring their kids to the beach. And when an African American friend of mine heard this story, he said, “Black families don’t take their kids to the beach” and explained how this was a vestige of a segregated era when African Americans were not allowed in public pools and beaches. Whatever the reason, I had missed something essential for connecting with my students: the historical, cultural, and economic context they brought to the classroom.

Accustomed to wearing multiple hats, Dunbar says that retirement means time to use his competition experiences to generate new projects. “One of the things I have been able to observe over 15 years is the creation of mathematical contest problems,” he says. “I’d like to think about the process of creating math questions. There are a lot of people who have written about how you solve problems, but not much written about how you pose problems,” he said. Whether he ends up writing an article or a book, he’s excited about delving into the issue as part of his future.

Lifetime of Experience New director Saul has had a lifetime of experience in math competitions. He has been a contestant, acted as a math team coach, and served on MAA competitions committees to develop and distribute the contests.

They are also used by more than 30,000 teachers in their classrooms to teach math skills, logical reasoning, problem solving, creative thinking, and perseverance. For this column, we will go one step further and explore some interesting variations of the game. The standard KenKen rules are simple: t For an n × n grid, fill each row and column with the numbers 1 through n. t Each heavily outlined set of cells, called a cage, contains a mathematical clue that consists of a number and an arithmetic operation. The numbers in the cage must combine (in any order) to produce the target number using the mathematical operation indicated. t Cages with just one cell should be filled with the target number. t Numbers can be repeated in a cage, as long as they are not repeated in any row or column.

PDDRUJSXEVIRFXVKWPOv-XQH-XO\v0$$)2&86 A MERICAN MATHEMATICAL SOCIETY

Search for an Executive Director for the American Mathematical Society

Position The Trustees of the American Mathematical Society seek candidates for the position of Executive Director of the Society to replace Dr. Donald McClure, who plans to retire in the summer of 2016. This position offers the appropriate candidate the opportunity to have a strong positive infl uence on all activities of the Society, as well as the responsibility of overseeing a large, complex, and diverse spectrum of people, publications, and budgets. The desired starting date is July 1, 2016.

Duties and terms of appointment The American Mathematical Society, with headquarters in Providence, RI, is the oldest scientifi c organization of mathe- maticians in the U.S. The Society’s activities are mainly directed toward the promotion and dissemination of mathematical research and scholarship, broadly defi ned; the improvement of mathematical education at all levels; increasing the apprecia- tion and awareness by the general public of the role of mathematics in our society; and advancing the professional status of mathematicians. These aims are pursued mainly through an active program of publications, meetings, and conferences. The Society is a major publisher of mathematical books and journals, including MathSciNet, an organizer of numerous meetings and conferences each year, and a leading provider of electronic information in the mathematical sciences. The Society maintains a Washington offi ce for purposes of advocacy and to improve interaction with federal agencies.

The Executive Director is the principal executive offi cer of the Society and is responsible for the execution and adminis- tration of the policies of the Society as approved by the Board of Trustees and by the Council. The Executive Director is a full-time employee of the Society appointed by the Trustees and is responsible for the operation of the Society’s offi ces in Providence and Pawtucket, RI; Ann Arbor, MI; and Washington, DC. The Executive Director is an ex-offi cio member of the policy committees of the Society and is often called upon to represent the Society in its dealings with other scientifi c and scholarly bodies.

The Society employs a staff of about 200 in the four offi ces. The directors of the various divisions report directly to the Executive Director. A major part of the Society’s budget is related to publications. Almost all operations (including the printing) of the publications program are done in-house. Information about the operations and fi nances of the Society can be found in its Annual Reports, available at www.ams.org/annual-reports.

The Executive Director serves at the pleasure of the Trustees. The terms of appointment, salary, and benefi ts will be consistent with the nature and responsibilities of the position and will be determined by mutual agreement between the Trustees and the prospective appointee.

Qualifi cations Candidates for the offi ce of Executive Director should have a Ph.D. (or equivalent) in mathematics, published research beyond the Ph.D., and signifi cant administrative experience. The position calls for interaction with the staff, membership, and patrons of the Society as well as leaders of other scientifi c societies and publishing houses; thus leadership, communica- tion skills, and diplomacy are prime requisites.

Applications A search committee chaired by Robert Bryant ([email protected]) and ([email protected]) has been formed to seek and review applications. All communication with the committee will be held in confi dence. Sugges- tions of suitable candidates are most welcome. Applicants can submit a CV and letter of interest to:
