Media coverage of the 2016 Breakthrough Prize to Ian Agol, by Annette Emerson The 2016 Breakthrough Prize in Mathematics was awarded to Ian Agol "for spectacular contributions to low dimensional topology and geometric group theory, including work on the solutions of the tameness, virtual Haken and virtual fibering conjectures." Agol is a professor of mathematics at University of California, Berkeley, currently on sabbatical at the Institute for Advanced Study in Princeton, NJ. (Photo of Ian Agol courtesy UC Berkeley.) "Agol studies the topology and geometry of threedimensional spaces, such as our own universe, and has won acclaim for solving five major conjectures by one of the giants in the field, the late William Thurston, a UC Berkeley alum," notes the UC Berkeley news release). "I tend to work very visually, or intuitively, which is something I learned from Thurston," Agol said. "I use my visual cortex to create a shorthand for something that can be very complicated to write down in a precise mathematical way. I try to teach this intuition to my students, too, though eventually you have to convert those visual ideas into equations to show that your intuitions are right." In Evelyn Lamb's piece, she explains the field of topology: "Agol's field, topology, is the branch of mathematics that pretends all shapes are made of putty or stretchy rubber. It studies those properties that remain the same when the space is squished or stretched, as long as there is no tearing or gluing. You can think of topological properties as the largescale properties of a space. Geometry, on the other hand, looks at finer properties, those that depend on exactly how the space is put together. Topologists have long had a fairly complete understanding of topology and geometry interact for twodimensional surfaces, or 2manifolds. Threedimensional manifolds are a different story. An appetizing way to understand 2manifolds and 3manifolds is to think of a doughnut. The glaze—the twodimensional donutshaped surface—is the 2manifold. The 3manifold is the whole doughnut, filling and all." She notes that "Agol provided answers to the last of [William] Thurston’s major lingering questions about 3manifolds.... [His] work gives researchers a way to study these hyperbolic 3manifolds using surfaces as well.... Specifically, Agol proved the virtual Haken and virtual fibering conjectures." And in response to learning he had won the award Agol said, "Finding out about the prize was never as exciting as the actual moment of thinking I had figured out the virtual Haken question." The award is US $3 million. As have all five past math laureates, Agol plans to give $100,000 of his prize winnings to support graduate students from developing countries through the Breakout Graduate Fellowships administered by the International Mathematical Union. The Breakthrough Prize was founded by Mark Zuckerberg and Yuri Milner. "Breakthrough Prize laureates are making fundamental discoveries about the universe, life and the mind," Yuri Milner said. "These fields of investigation are advancing at an exponential pace, yet the biggest questions remain to be answered." This award ceremony was broadcast live on National Geographic Channel November 8, 2015. See video clips, including a video of Agol on "The Beauty of Mathematics."

Annette Emerson On American Students' Drop in Math Skills, by Samantha Faria Despite more testing and a new curriculum the results of a nationwide test reveal that American students' math skills have slipped. Education officials did not expect this and have suggested multiple reasons as potential causes for the drop. Some educators blame the Common Core curriculum and believe that it has caused confusion among teachers and students. "Right now, what’s going on in many states is a wholesale change in math instruction," said Daniel Koretz, a professor of education at Harvard. The Obama administration weighed in that there are too many highstakes tests and admonished school districts to cut down on, "the number of tests and make them more purposeful." The gap in school success between white and minority students is ever present as well as the gap between children from affluent and poor families. William J. Bushaw, the executive director of the National Assessment Governing Board, which sets policies and achievement levels for the tests, optimistically explained, "It's not unusual when you see lots of different things happening in classrooms to first see a slight decline before you see improvement." See "Nationwide Test Shows Dip in Students' Math Abilities," by Motoko Rich, New York Times, Oct. 28, 2015.  Samantha Faria (Posted 11/6/15) On advances in graph theory, by Annette Emerson "Four years ago, the mathematician Maria Chudnovsky faced an alltoocommon predicament: how to seat 120 wedding guests, some of whom did not get along, at a dozen or so conflictfree tables." What a great beginning of this article about graph theory by Natalie Wolchover, who continues, "Luckily, the problem fell squarely in her realm of expertise. She conceived of the guests as nodes in a network, with links between incompatible nodes. Her task was to color in the nodes using a spectrum of colors representing the different tables. As long as connected nodes never had the same color, there would be no drama at the reception." The article explains that "Networks of related objects, be they nodes or wedding guests, are known to mathematicians as 'graphs,' and graph coloring is the muchstudied act of partitioning these objects into conflictfree sets." Chudnovsky and her collaborators are working towards proving a theorem for coloring all "perfect graphs," which are explained by Wolchover.
The article includes several illustrations and this interactive by Andrew Silver for Quanta Magazine: "Select a color and then a node to color in this simple perfect graph. When the entire graph is colored in, "Check" that no connected nodes share the same color." See "Theorists Draw Closer to Perfect Coloring," by Natalie Wolchover, Quanta Magazine, 20 October 2015.  Annette Emerson (Posted 10/20/15) On the bicentenary of the birth of George Boole, by Mike Breen This year, specifically November 2, marks the 200th anniversary of British mathematician George Boole's birth. Boole came up with an algebraic formulation of the laws of logic, which now govern the basic operations of computers. In the past year, University College Cork in Ireland, where Boole became the university's first professor of mathematics, and the University of Lincoln, in his hometown, have organized many events to honor Boole, including showing a film narrated by Jeremy Irons, The Genius of George Boole. Virginia Teehan, director of cultural projects at University College Cork, which commissioned the film, says about Boole, "The application of his research has been vital in all new technologies today, and he hasn’t been recognised." See "How a Victorian mathematics don became a digital pioneer," by Nicola Davis. The Guardian, 17 October 2015.  Mike Breen (posted 10/20/15, 1/1/1 in Boolean algebra) On recreational mathematics, by Claudia Clark In this opinion piece, University of Maryland mathematics professor Manil Suri discusses the importance of recreational math, in general, and the work of Martin Gardner, in particular. He recalls Gardner’s "Mathematical Games" series, which "introduced millions worldwide to the joys of recreational mathematics" in its over 25year run in Scientific American. Each of Gardner's puzzles "required different, inventive techniques to crack. The solution in such puzzles usually pops up...through a flash of insight, rather than emerging steadily via stepbystep deduction as in Sudoku," Suri writes. "Mr. Gardner's great genius lay in using such basic puzzles to lure readers into extensions requiring pattern recognition and generalization, where they were doing real math." Gardner himself was a longtime advocate of including recreational math in school curriculums: in his August 1998 column, he opined that "it should be regularly introduced as a way to interest young students in the wonders of mathematics." Indeed, a recently published paper in the Journal of Humanistic Mathematics "points out that recreational math can be used to awaken mathematicsrelated 'joy,' 'satisfaction,' 'excitement' and 'curiosity' in students," a goal reflected in the educational policies of many countries. While such goals are not part of the Common Core standards, Suri reports that some school districts are incorporating recreational mathematics into their curriculum.

Claudia Clark Honoring William Rowan Hamilton, by Samantha Faria In an effort to spruce up the city of Dublin, city council members sought out people to paint trafficlight boxes to make them more interesting. Rob Doyle took this opportunity to honor mathematician, William Rowan Hamilton. "Hamilton had invented a game called the Icosian game, so the shape of the Icosian game is the basis for the stencil [at left]," Doyle explained. He went further to insure that the number of faces in the design of the perimeter of the final illustration equaled the number of letters in Hamilton’s full name. Although a 19th century mathematician, Hamilton continues to inspire portraits, illustrations, sculptures, stamps, poetry, documentaries, and literature. Annually, people gather to retrace his steps along the Royal Canal where he famously carved his formula for quaternions. (Photo from The Irish Times of art by Rob Doyle in Cabra, near Dublin.)

On an interview with Talithia Williams on increasing opportunities for minorities in STEM, by Annette Emerson Maria Klawe, president of Harvey Mudd College, talks with Harvey Mudd mathematics Professor Talithia Williams about an annual math and science conference for African American middle and high school girls to get them interested in and excited about STEM careers. Williams started the conference, now in its fourth year, in partnership with Sacred SISTAHS (Sisters In Solidarity Teaching And Healing our Spirit), a local nonprofit organization. "We engage the girls in fun, handson math and science lessons. For example, one of our math professors led a session in which the girls related math concepts to handson experiments in fluid dynamics. I led a session on working with data and how to use statistics to better understand ourselves and our world. A local graphic artist taught a session on how she uses computer graphing techniques and software in her work. In both the talks and the handson activities, we showcase African American women who are successful and excited about their careers in STEM. We try to get the girls excited about studying math, science and engineering." Williams says the girls will struggle, but she tells them it's important for them to work hard and seek help. Williams herself is a role model, and says, "I know from my own experience that seeing a role model who looks like you, who is successful in a STEM career, can be a pivotal moment." In sessions for parents the conference covers "The top 10 questions you should ask your daughter's guidance counselor," and gives parents a list of courses their daughters should take to prepare for college.

Annette Emerson (Posted 10/13/15) On Émilie du Châtelet, by Claudia Clark "A spirited debate raged in 18th century Europe about what was driving the movements of the planets," the article begins. "In England, Sir Isaac Newton and his followers said it was gravity....On the other side of the Channel, many Continentals favoured René Descartes' theory of a swirling cosmic 'ether' that... swept up the planets in its wake." The author goes on to discuss the life and work of Émilie du Châtelet, a mathematician who, with playwright, Voltaire, championed Newton's theory of planetary motion in Continental Europe. Born in 1706 in Paris to an aristocratic family, Châtelet was "passionate in both her intellectual and amorous pursuits." She educated herself in higher mathematics and physics. Her initial fame came from the book Institutions de Physique (Fundamentals of Physics), in which she "bravely attempted to integrate the work of Newton and Leibniz," according to Arianrhod. "Émilie's brilliance lay in her ability to understand the subtleties of both Newton's theory and Leibniz's philosophy." Her later work “includes what is still the definitive French translation of Newton's Principia," as well as a 180page appendix, which included "her own reworking of some of the Principia's key proofs in the language of calculus."

 Claudia Clark On the math of wing design, by Lisa De Keukelaere Insect Wing Flutter Captured with Phantom HighSpeed Digital Camera, by Vision Research. Using modeling software and a single differential equation, Florida State University mathematician Nick Moore calculated the ideal distribution of wing flexibility for an object to take flight, as detailed in a recent paper in the Physics of Fluids journal. While most airplane wings are rigid, highspeed camera shots of insects in flight shows that their wings are flexible, which suggests that this feature could improve performance in manmade devices. Testing the thrust production for various distributions for flexibility along the length of a wing, Moore’s models showed that a linear distribution with highest flexibility at the front of the wing is more efficient in producing thrust than a uniform distribution of flexibility, whereas a rigid wing is least efficient. His results also indicated that a torsional spring—a portion of the wing that twists as the wing flaps—can increase thrust production by up to 36% over wings with variable flexibility. See "Mathematics For Optimal Wing Design," by Kevin Knudson, Forbes, 2 October 2015 and "Torsional spring is the optimal flexibility arrangement for thrust production of a flapping wing," by M. Nicholas J. Moore, Physics of Fluids, Volume 27, 091701 (2015); doi: 10.1063/1.4930235.  Lisa DeKeukelaere On a physicist's dim view of probability theory, by Allyn Jackson In this short piece, quantum information researcher David Deutsch discusses what he sees as misplaced faith in the use of probability theory in physics. He notes that probability theory can work as an approximation to reality, just as the theory that the Earth is flat can work when you are laying out your garden. But both theories have severe limitations. Deutsch writes: "The awful secret at the heart of probability theory is that physical events either happen or they don't: there's no such thing in nature as probably happening." See "Probability is as useful to physics as flatEarth theory," by David Deutsch. New Scientist, 30 September 2015. (Full access to the article requires a subscription.)  Allyn Jackson (Posted 10/13/15) On quant investing, by Lisa DeKeukelaere John Overdeck, a math genius who won a silver medal at the International Mathematics Olympiad at age 16, has parlayed his math skills into an estimated net worth of $2.8 billion from his Wall Street hedge fund, one of the biggest in America. Last year, Overstock bested other top mathematicians, including a Fields Medal winner, at an annual Museum of Mathematics soiree that included a competition to solve a series of complex equations. Overstock's firm, Two Sigma Investments, uses mathematics to predict stock prices—one of many successful trading operations driven by math experts known as quants. As a result of Two Sigma's success in achieving a high average return, the firm is able to charge higher fees than its competitors, further boosting its earning potential.
