The current dean, Kirk Johnson, a professor of sociology, is retiring at the end of spring quarter.</span></p><p>Currently Englund serves as an associate dean in the college and has been successful in several COTS initiatives. Prior to joining the dean's office, he served one term as chair of the Mathematics Department and as the faculty coordinator for the Ronald E. McNair Scholarship program at CWU.</p><p>“I’m looking forward to serving the university in the role of interim dean,” said Englund. “My goal is to continue and complete many of the important projects that were started during Dean Johnson’s tenure, and provide support and leadership for our faculty.”</p><p>“Tim has brought leadership skills to his role as associate dean that will transfer very nicely to his new role as interim dean. He will provide the experience and knowledge of COTS that is needed,” said Provost Marilyn Levine.</p><p>Englund received his bachelor’s degree from Grand Valley State University, in Allendale, Michigan, and earned his doctorate from Michigan State University. He has been a member of the CWU mathematics faculty since 1998. His current primary research interests include interdisciplinary collaborations with colleagues in Nutrition and Health Sciences examining elementary school lunches. Previously, his research focused on the representation theory of Chevalley groups.</p><p>A dedicated ultramarathoner, Englund routinely participates in 50-mile (and longer) competitions. He recently raced—and won—the Big’s Backyard Ultra in Tennessee. Englund outlasted the field of 40 runners by running a total of 145.8 miles over a span of 35 consecutive hours. Big’s Backyard Ultra was a last-man-standing format, which is different than most ultras. The event was started as a fundraiser to help pay vet bills for an injured pit bull named Big.</p><p>The College of the Sciences is comprised of thirteen academic departments and eleven interdisciplinary programs in the natural, behavioral, social, and computational sciences. The college is also home to a number of affiliated programs focused on education, student learning, and research projects. The college currently consists of 170 full- and 62 part-time faculty and 40 staff located on the main campus in Ellensburg and at the Des Moines, Lynnwood, Moses Lake, Pierce, Wenatchee, and Yakima University Centers.</p><p>Media Contact: Valerie Chapman-Stockwell, Public Affairs, 509-963-1518, valeriec@cwu.edu<br>&nbsp;</p></span style="line-height: 1.4;"></span style="line-height: 1.4;"></br>Free Program Helps Parents Understand, Have Fun with the New Mathhttp://www.cwu.edu/math/node/2592Mon, 20 Apr 2015 15:19:51<p>Parents, are you having trouble helping your elementary or middle school student with math?

Both CWU teams earned a Meritorious ranking—one of the highest honors teams can receive. CWU was one of only three schools in the United States in which all the teams were rated as Meritorious.</p><p>“I’ve known that our students were exceptional, but to see both teams score this high is really extraordinary,” said James Bisgard, mathematics professor and the advisor to CWU’s modeling teams. “In the seven years I’ve advised teams, we’ve had a total of ten teams compete.”</p><p>The MCM is an annual international competition, with teams of three students developing and analyzing mathematical models to address real world questions. This year's competition had a choice of two challenges. In one, the team would develop a ranking for college coaches over all sports and times periods. In another, the team would develop a model for traffic flow determining whether or not the keep-right-except-to-pass rule is useful.&nbsp;</p><p>The two MCM teams chose different problems. The team of John-Paul Mann, Nathan Minor, and Benjamin J. Squire chose Problem A, the Keep-Right-Except-To-Pass-Rule. Adam Brand, Albany Thompson, and Nathaniel Deardorff chose Problem B, College Coaching Legends.</p><p>“The MCM is one of the greatest opportunities I've been involved with thus far in my college career,” said John-Paul Mann, a senior who is majoring in both mathematics and physics. “It provided a great opportunity to apply all the skills I've developed throughout my studies, including math, physics, logic, data analysis, effective essay writing, and most importantly team collaboration. Having all our hard work and hours pay off with a great standing in the competition wasn't too bad either.”</p><p>Such problems are exceptionally difficult, because of the inherent vagueness of “best” or “useful.” As a result, there is no single right answer for these types of problems. Teams are judged by the cleverness of their model, as well as how well they communicate their model and its results in a written report.</p><p>The MCM competition lasts only 96 hours: from 5:00 p.m. on Thursday until 5:00 p.m. the following Monday (Pacific Standard Time). Teams must work almost around the clock to develop a model and to write a report. This year’s competition was held February 6-10 and judging was completed in March. The results will be posted on April 29.</p><p>The MCM is sponsored by COMAP, the Consortium for Mathematics and Its Applications, an award-winning non-profit organization whose mission is to improve mathematics education for students of all ages. Since 1980, COMAP has worked with teachers, students, and business people to create learning environments where mathematics is used to investigate and model real issues in our world.</p><p><br>Media Contact: Valerie Chapman-Stockwell, Public Affairs, 509-963-1518, valeriec@cwu.edu</p><p>&nbsp;</p></br>Attention Spy Kids!

Now students have a chance to see if they have what it takes to be a code breaker!</p><p>The Kryptos competition is a unique codebreaking challenge developed by Central Washington University mathematics professor Stuart Boersma, and his colleague, Cheryl Beaver, a Western Oregon University mathematics professor.

Even if you don’t qualify as a contestant, you can go to the Kryptos website, www.cwu.edu/math/kryptos, to look at the previous years’ challenges and solutions—and test your skills as a cryptanalyst.</p><p>According to Boersma, who is teaching an upper level mathematics course in cryptology this spring, many of the challenges are based on historical ciphers that pre-date World War II. And while computers can be helpful in breaking some of the codes, most can be solved—if a little tediously—with paper and pencil.&nbsp;</p><p>“The main objective is to have fun,” said Boersma. “Most students with a little familiarity with ciphers or code-breaking will be able to solve the challenges. They aren’t overly technical nor do they use advanced mathematical algorithms.”</p><p>He continues, “While we haven’t had a challenge in Navajo—yet—there was an audio challenge in a previous year!”</p><p>When the contest begins at 4:00 p.m. on April 10, the 2014 Cipher Challenges will be posted on the Kryptos website.

The Navajo code was based on: 1) the Navajo language—an extremely difficult language; and 2) a code embedded in the language, meaning that even native speakers would be confused by it. Supposedly, this code was close to unbreakable, and so difficult that only a few people could actually learn it.

Weird numbers. Mozart. What do these things have in common? They have Dominic Klyve [KLEE-vee], an uncommonly gifted mathematics professor at Central Washington University.</p><p>Klyve recently received the national Henry L. Alder Award for Distinguished Teaching from the <a href="http://www.maa.org">Mathematics Association of America</a>. Klyve is the first winner from Washington State in the 18-year history of the award. The Alder Award goes to individuals whose teaching has been extraordinarily successful and who have had influence beyond their own classrooms.</p><p>“I’m absolutely thrilled,” said Klyve. “It gives national recognition to my department and my students, as well as being a tremendous honor for me. This wouldn’t have been possible if I had been at an institution other than Central—because our math department is so good, and is so deeply engaged in teaching.”</p><p>In his first four years at Central, he has taught a surprising variety of classes, developed new ones, and founded a Mathematics Honors Program. He has engaged first-year statistics students in analyzing a countywide nutrition survey, where they discovered a statistically significant link between freezers and hunger. His undergraduate students have recently discovered the largest weird number* in the world. And he has developed a Math 101 class for music majors that explores regression and correlation in Mozart’s sonatas.</p><p>“I have to give credit to my colleagues for so much of this,” he enthused. “Ian Quitadamo [science education professor] encouraged me to involve my students in community-based inquiry. The math and music class was created by Todd Shiver [music chair and professor. I’m especially grateful to my chair, Tim Englund for nominating me for this award.”</p><p>In this collegial atmosphere, Klyve has flourished as a teacher who, according to one undergraduate, instills “a lingering love for mathematics” in his students. He is a regular speaker on mathematics (and a teacher of juggling!) at Wisconsin's Suzuki music festival. In fact, he is so intrigued with juggling that he formulated an equation that mathematically determines how juggling balls fall (“A Zeta Function for Juggling Sequences,” Journal of Combinatorics and Number Theory, 01/2012).</p><p>He has already built a reputation as a popular lecturer. He has been invited to schools throughout the United States to speak about his work.&nbsp; In 2013, the University of Canterbury brought him to New Zealand to teach a five-week course in the History of Mathematics.</p><p>He is currently working on a grant to teach math using original, historical sources and has recruited dozens of mathematicians across the country to develop projects to teach math using the history of mathematics.</p><p>Klyve was also cited for combining teaching with scholarship.</p><p>“Undergraduate research is really important to me,” he said, “and I’m lucky that so many CWU students are interested in pursuing research projects.”</p><p>Since coming to Central four years ago, he has written six papers with students for publication in international research journals. He is a Councilor on the national “Council on Undergraduate Research,” and will serve as the first president of the Math Association of America’s Special Interest Group on Undergraduate Research.</p><p>Klyve<span style="line-height: 1.4;"> also teaches for the William O. Douglas Honors College at </span>CWU<span style="line-height: 1.4;">. He has had multiple courses accepted by the </span>DHC<span style="line-height: 1.4;"> Advisory Committee and he is consistently one of their most beloved and popular professors</span></p><p>In addition to his college coursework, he is active in working with high school students. In addition to bringing the American Mathematics Competition to Ellensburg two years ago, he teaches under-represented and first-generation high school students during the summers as part of the Upward Bound Program.</p><p>“I’ve known for a long time that I love math, and I love explaining things to people,” said Klyve. “I’m grateful to have a supportive department and chair that allow me the freedom to pursue what I love to do.”</p><p><br>*Weird numbers are those in which no combination of its divisors adds up to the original number. For example, the smallest weird number is 70; its divisors are 1, 2, 5, 7, 10, 14, and 35.

In this case, a weird number is one in which no combination of its divisors add up to the original number. Divisors are numbers that can be divided into a whole number to yield a quotient that is a whole number. For example, in the smallest weird number, 70, its divisors are 1, 2, 5, 7, 10, 14, and 35. No combination of these numbers will add up to 70. Weird!</p><p>According to Dominic Klyve, CWU mathematics professor and advisor, a better understanding of weird numbers leads to a better understanding of factorization, which is the basis of all modern cryptography—the art of writing or solving codes.</p><p>No one knows how common weird numbers are, and looking for big ones is hard. Until last week, the previous record had stood for more than 35 years—the reigning champion was a 53-digit number discovered by Stanley Kravitz in 1976. Then a group of five CWU students—Luke Campbell, Anna Cockrum, Jacob Darst, Jeremy Klarich, and Michael McDonald—together with Klyve, decided to try to find a bigger one.&nbsp;</p><p>Such a search requires both creative thinking and computing power. Bill Glessner of CWU’s Networks and Operations division of the Information Technology office set up several old research computer clusters for students and faculty. By working quickly during seminar, and holding early morning meetings to pursue their mathematics before classes started, the math team found a way to use Kravitz’s ideas from his 1976 paper to look for weird numbers on some of these computer clusters.</p><p>Their method quickly proved successful. They broke Kravitz’s record by finding a 74-digit weird number. Encouraged by their success, they pushed their calculations further—at last count, they had found over a dozen numbers which break the old record—the largest so far is 127 digits. They plan to keep working through Christmas break, and hope for several new world records in the near future.</p><p>Media Contact: Valerie Chapman-Stockwell, Public Affairs, 509-963-1518, valeriec@cwu.edu</p>CWU Actuarial Science Alumni Spotlightedhttp://www.cwu.edu/math/node/2499Mon, 19 Aug 2013 10:15:58<p><img alt="" src="/math/sites/cts.cwu.edu.math/files/images/grahamvickydyer.png" style="width: 550px; height: 221px; "></p><p>The profession of actuary has been named the best job for 2013 by CareerCast, one of the Internet's premier career sites.
