Peter Winkler, Dartmouth College
Wednesday, April 23, 2014

Abstract: Some games are designed to be thought about, rather than actually playedone example is Chomp, a favorite of Paul Halmos. We'll talk about Chomp and some other provocative games, and perhaps figure out how we would play them if our lives depended on winning.

Biography: Peter Winkler is William Morrill Professor of Mathematics and Computer Science at Dartmouth College. He is the author of 140 research papers, two books on mathematical puzzles, a book on cryptology in the game of bridge, a portfolio of compositions for ragtime piano, and a dozen patents in cryptography, holography, distributed computing, optical networking, and marine navigation.

Winkler is a past winner of the Lester R. Ford Award for mathematical exposition, and a 2011 winner of the MAA's David P. Robbins Award for his part in determining how far a stack of bricks can be made to hang over the edge of a table.

Colm Mulcahy, Spelman College and American University
Tuesday, April 1, 2014

Abstract: The theme of Mathematics Awareness Month 2014, which launches April 1, is "Mathematics, Magic, and Mystery," which is closely patterned after the title of a classic 1956 Dover paperback by the legendary Martin Gardner (1914-2010). Mathematics Awareness Month will provide people with multimedia opportunities to explore 30 updated takes on the kinds of topics Martin made famous via his 300-odd "Mathematical Games" columns for Scientific American, and associated books. These range from hexaflexagons, magic squares, geometric vanishes, möbius bands, and mathemagic, to juggling, Penrose tiles, and the connection between card shuffling and fractals. I'll provide sneak previews of several of these activities, while surveying Martin Gardner's achievements, and highlighting the potential for outreach to the nation's youth.

Biography: Colm Mulcahy is a professor of mathematics at Spelman College, in Atlanta, where he has taught since 1988. He's currently visiting American University in Washington, D.C. Over the last decade, he has been at the forefront of publishing new mathemagical principles and effects for cards, particularly in his long-running bimonthly Card Colm column for the MAA. Some of his card effects have been featured in the New York Times Numberplay blog. His book Mathematical Card Magic: Fifty-Two New Effects was published by AK Peters/CRC Press in 2013.

Mulcahy’s interests are broad, ranging from algebra and number theory to geometry. He earned a B.Sc. and M.Sc. in mathematical science from University College Dublin in his native Ireland, and a Ph.D. from Cornell University for research in the algebraic theory of quadratic forms, under Alex F.T.W. Rosenberg.

Mulcahy gave the MAA Lecture for Students at MAA MathFest 2009 in Portland, Oregon, and is a recipient of MAA's Allendoerfer Award for excellence in expository writing, for an article on image compression using wavelets. He's part of the team heading up Mathematics Awareness Month 2014, which is inspired by the legacy of Martin Gardner, whom he was fortunate to know for the last decade of his life. He also chairs the Martin Gardner Centennial Committee.

Mulcahy tweets at @CardColm and highly recommends that Gardner fans follow @WWMGT and @MGardner100th. Twitter users may also enjoy following @MathAware (Mathematics Awareness Month).

Glen Van Brummelen, Quest University Canada

cosponsored by HOM SIGMAA (History of Mathematics)

Abstract: Although all triangles (plane and spherical) could already be solved in the early 16th century, trigonometry advanced almost beyond recognition by the time logarithms were invented in 1614. From just the sine function, all six of our current functions were born. With the new functions and the numerical tables that came with them, the theory could be enhanced, simplified, and made more elegant. Most crucially, rather than existing simply as a handmaiden to the astronomy that had given it life, trigonometry became a powerful tool in geography, optics, navigation, surveying, even architecture. This was the period, and trigonometry was the subject, that placed mathematics at the center of a quantitative scientific approach to our world that still flourishes today.

Biography: Glen Van Brummelen of Quest University Canada is a historian of mathematics, especially trigonometry and astronomy in ancient Greece and medieval Islam. He is president of the Canadian Society for History and Philosophy of Mathematics (2012-14), and governor-at-large for Canadian members of the Mathematical Association of America (2013-16). In addition to authoring 30 scholarly and 15 encyclopedia articles, he is co-editor of Mathematics and the Historian's Craft (Springer) and author the first history of trigonometry in over a century (The Mathematics of the Heavens and the Earth: The Early History of Trigonometry, Princeton University Press). Van Brummelen recently published Heavenly Mathematics: The Forgotten Art of Spherical Trigonometry (Princeton) and finished co-editing with Nathan Sidoli From Alexandria, Through Baghdad: Surveys and Studies in the Ancient Greek and Medieval Islamic Mathematical Sciences in honor of J. L. Berggren (Springer, 2014).

Laura Taalman, James Madison University
Wednesday, February 19, 2014

Abstract: For a pure mathematician, mathematics is a set of abstract constructs completely separated from reality, and using technology to explore mathematics can seem like, well, cheating. But with the rise of undergraduate research in mathematics comes a need for elementary unsolved problems that students can pursue. Modern technology can help fill this need and support exploratory, investigative mathematics, even for those of us who are old-school mathematical purists at heart. Going a step further, the recently accessible technology of 3D printing can take abstract mathematical objects and literally make them real. A 3D printing demonstration will accompany this talk.

Biography: Laura Taalman is a Professor in the Department of Mathematics and Statistics at James Madison University, where she joined the faculty after graduate work at Duke University and undergraduate work at the University of Chicago. Her mathematical research interests include singular algebraic geometry, knot theory, and the mathematics of games and puzzles. Dr. Taalman is the director of the JMU MakerLab mathematical 3D-printing lab and the JMU 3-SPACE general education 3D-printing classroom. She is a co-author of the recent Taalman/Kohn Calculus textbook and seven books on Sudoku and mathematics. In 2013 she was a recipient of the Outstanding Faculty Award from the State Council of Higher Education for Virginia, and has received the Alder Award and the Trevor Evans Award from the Mathematical Association of America.

William Dunham, Muhlenberg College
Tuesday, January 28, 2014

Abstract: Almost fifty years ago, Cambridge University Press published the correspondence of Isaac Newton, a seven-volume, 3000-page collection of letters that provides insight into this great, if difficult, genius. In this talk, I share my favorite examples of Newton as correspondent. From his earliest known letter in 1661 (where he scolded a friend for being drunk), through exchanges with Leibniz, Locke, and others, to documents from his days at the Mint in London, these writings give glimpses of Newton at his best…and his worst. 

To add a bit of mathematics to the narrative, I stop to take a look at his first great mathematical discovery—the generalized binomial theorem as described in a 1676 letter to Leibniz—and show how “…the extraction of roots is much simplified by this theorem.” I’ll end with Newton’s most-quoted line about standing on the shoulders of giants and how my search for its place of origin led me, improbably, to a library in Philadelphia.

Biography: William Dunham has been the Truman Koehler Professor of Mathematics at Muhlenberg College since 1992. His books Journey Through Genius: The Great Theorems of Mathematics (Wiley, 1990) and The Mathematical Universe (Wiley, 1994) were alternate selections for Book-of-the-Month Club, and the latter received the Association of American Publishers Award as the Best Mathematics Book of 1994. His next two books, Euler: The Master of Us All (MAA, 1999) and The Calculus Gallery: Masterpieces from Newton to Lebesgue (Princeton, 2005), were designated among their year’s Outstanding Academic Titles by Choice magazine of the American Library Association, and the Euler book received the MAA’s Beckenbach Prize in 2008. He has also edited a volume, The Genius of Euler: Selections from His Life and Work (MAA, 2007) and is featured in the Teaching Company’s DVD, “Great Thinkers, Great Theorems.”

Dunham’s interest in the history of mathematics has led to numerous talks at colleges and universities around the country and has carried him to speaking engagements at the Smithsonian Institution, on NPR’s “Talk of the Nation: Science Friday,” and at the Swiss Embassy in Washington, DC. In the fall of 2008 and again in the spring of 2013, he was a visiting professor at Harvard University, where he taught an undergraduate course on the mathematics of Leonhard Euler (course title: “Much Ado About Everything”). After stepping down from his Muhlenberg position in December of 2013, Dunham will be a visitor at Princeton University (spring, 2014) and then at the University of Pennsylvania (fall, 2014), and he hopes to continue as an itinerant math historian into the foreseeable future.
