The American Mathematical Society was a Palladium Sponsor and Exhibitor at the second USA Science & Engineering Festival (USASEF), the nation's largest celebration of science and engineering, held April 28-29, 2012 in Washington, D.C.
The AMS activities for visitors--making stick knots--were led by Lew Ludwig, associate professor at Denison University, and four of his undergraduate mathematics students: senior Nathan Zakahi, math and computer science major from Mankato, MN; sophomore Janie Frandsen, biochemistry major, math minor, from Albion, MI; junior Holly Wilson, math and East Asia studies major from Farmersville, OH; and sophomore Paul Yang, math and physics major from Chengdu, China. Mike Breen, AMS Public Awareness Officer, and Anita Benjamin, Assistant Director, AMS Washington Office, also helped with the activity.
The knot-making activities drew nearly 2,000 visitors of all ages. They created their own mini-version of a mathematical stick knot using small wooden dowels and plastic tubing, and over 750 young people attached their constructed knot to a lanyard to wear at the festival and take home. Others experimented with different lengths of plastic pipes and 90-degree elbows to create a particular knot with as few sticks as possible.
As Ludwig notes, "One of the great things about studying knot theory is that it is very hands-on. Take a piece of string, tie a knot into it and glue the ends together into a closed loop, and you have a mathematical knot. Knot theory is a relatively new branch of mathematics; it is roughly one hundred years old. Interestingly, a good deal of the work done in the last twenty years has included undergraduate students. Knot theory is one of the few branches of mathematics accessible to a wide audience." Read about the Unknot Conference 2012.

The USASEF is a grassroots collaboration of over 500 of the U.S. leading science and engineering organizations to increase public awareness of the importance of science and to encourage youth to pursue careers in science and engineering by celebrating science in much the same way as we celebrate Hollywood celebrities, professional athletes and pop stars. The free, family-friendly event drew over 150,000 kids and adults to participate in over 2,000 hands-on activities and see more than 200 live performances by science celebrities, explorers, best-selling authors, entrepreneurs and world-renowned experts. Below is a slideshow of just some of the many activities.
The AMS also hosted Who Wants to Be a Mathematician on Saturday, April 28. The contestants were from high schools in DC, VA, and MD. Daniel Yang, a junior at Urbana High School in Maryland, won US$3000!
