<p><strong>Abstract: </strong>Convex polyhedra are familiar objects. Cubes and pyramids are common in kindergartens. Polyhedra, in their high-dimensional versions, are widely used in applied mathematics. Their beauty and simplicity appeal to all, but very few people know of the many easy-to-state but difficult-to-solve mathematical problems that hide behind their beauty.This lecture introduces the audience to some fascinating open questions on the frontiers of mathematical research and its applications.</p>

<p><strong>Abstract: </strong>Chaos is a real-world phenomenon that arises in many different contexts, making it difficult to tell exactly what chaos is. Yorke will give examples of the aspects of chaos.</p>
<p><strong style="line-height: 1.25em;"><img alt="" src="/sites/default/files/images/dist-lecture/jyorke.jpg" style="width: 208px; height: 208px; float: left; margin: 5px;" />Biography: </strong><span style="line-height: 1.25em;">James A. Yorke earned his bachelor's degree from Columbia University in 1963. He came to the University of Maryland for graduate studies, in part because of interdisciplinary opportunities offered by the faculty of the Institute for Physical Sciences and Technology (IPST). After receiving his doctoral degree in 1966 in Mathematics, Yorke stayed at the University as a member of IPST. Today he holds the title of Distinguished University Professor and also is a member of the Mathematics and Physics Departments.</span></p>
<p>Professor Yorke's current research projects range from chaos theory and weather prediction and genome research to the population dynamics of the HIV/AIDS epidemic. He is perhaps best known to the general public for coining the mathematical term "chaos" with T.Y. Li in a 1975 paper entitled "Period Three Implies Chaos," published in the <em>American Mathematical Monthly</em>. "Chaos" is a mathematical concept in nonlinear dynamics for systems that vary according to precise deterministic laws but appear to behave in a random fashion.</p>

<div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p><strong>Rebecca Goldin, George Mason University</strong><br />
<strong>Tuesday, October 28, 2008 </strong></p>
<p><b>Abstract: </b>News increasingly depends on a careful dissection of numbers. Statistics are everywhere, from how many people lack health insurance to how to improve math education. Yet for being so prevalent, statistics are badly understood by the general public.</p>
<p>Mark Twain popularized the quote that "There are three kinds of lies: lies, damn lies, and statistics." While this quote suggests the scary idea that statistics can be manipulated to say anything, I will argue that statistics can tell us lots of useful things when used appropriately, and that the more the media does this for us, the more educated we can be as news consumers, and the better we will be at truly evaluating risk for ourselves and others.</p>
<p>In this talk, I'll illustrate how the press can misuse and even abuse statistics using examples of news coverage. Since news sources are the main avenue by which the public understands many public health issues, these misguided representations of science can actually shape public policy, legislation, and individual choices. We will see why it is so important that media writers understand basic concepts from statistics, epidemiology and even toxicology. I will also show how powerful the work can be when the press goes beyond politics and morality to point out what science says, what it doesn't, and what it can't.</p>

<p><strong>Abstract: </strong>Regular patterns appear all around us: from vast geological formations to the ripples in a vibrating coffee cup, from the gaits of trotting horses to tongues of flames, and even in visual hallucinations. The mathematical notion of symmetry is a key to understanding how and why these patterns form. In this lecture Professor Golubitsky will show some of these fascinating patterns and explain how mathematical symmetry enters the picture. </p>

<div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p><strong>David Bressoud, Macalester College</strong></p>
<p><strong>Abstract: </strong>What is the role of proof in mathematics? Most of the time, the search for proof is less about establishing truth than it is about exploring unknown territory. In finding a route from what is known to the result one believes is out there, the mathematician often encounters unexpected insights into seemingly unrelated problems. I will illustrate this point with an example of recent research into a generalization of the permutation matrix known as the "alternating sign matrix." This is a story that began with Charles Dodgson (aka Lewis Carroll), matured at the Institute for Defense Analysis, drew in researchers from combinatorics, analysis, and algebra, and ultimately was solved with insights from statistical mechanics. This talk is intended for a general audience and should be accessible to anyone interested in a window into the true nature of research in mathematics.</p>

<strong>Friday, December 8, 2010</strong></p>
<p><strong>Abstract: </strong>When you send your credit card number over the Internet, cryptography helps to ensure that no one can steal the number in transit. Julius Caesar and Mary Queen of Scots used cryptography to send secret messages, in the latter case with ill-fated results. More recently, cryptography is used in electronic voting, and it is also used to "sign" documents electronically. While cryptography has been used for thousands of years, public-key cryptography dates only from the 1970's. Some recent exciting breakthroughs in public-key cryptography include elliptic curve cryptography, pairing-based cryptography, and identity-based cryptography, all of which are based on the number theory of elliptic curves. This talk will give an elementary introduction to cryptography, including elliptic curve and pairing-based cryptography.</p>

<p>The picture of what we call “hyperbolic wallpaper” helps us imagine this cosmos: In the world of the shrinking ruler, all of the peacock fans are exactly the same distance across. All of them. And there are infinitely many copies hidden down there near the edge, unseen by our outsider eyes.</p>

<p><strong>Abstract: </strong>In the world of discrete mathematics, we encounter a bewildering variety of topics with no apparent connection between them. There are block designs in combinatorics, finite projective planes in geometry, round-robin tournaments and map colorings in graph theory, (0, 1)- matrices in linear algebra, quadratic residues in number theory, error-correcting codes on the internet, and the torus at the doughnut shop.</p>
<p>But appearances are deceptive, and this talk is about the (7,3,1) design, a single object with many names that connects all of these topics. Along the way, we'll learn how Leonhard Euler was once spectacularly wrong, how P. J. Heawood was almost completely right, and what happened when Richard Hamming got mad at a computer.</p>
