Follow the Leader
In the sport of orienteering, a competitor uses a detailed map (and perhaps a compass) to navigate his or her way across varied terrain following a course drawn on the map. Selecting the best available route, each participant races from one marker to the next in the required sequence. The winner is the person who […]

Sand Drawings and Mirror Curves
To accompany the telling of a story or recounting of a fable, men of the Chokwe people in south-central Africa traditionally made sand drawings, called sona, to illustrate the tale. These highly stylized geometric illustrations also served as memory aids. Sand drawing. Paulus Gerdes Plaited mat designs. Mark Schlatter Lion’s stomach design. Mark Schlatter Example […]

Waves of Congestion
You’re confined to a single lane as you drive along a narrow, winding road. The car in front of you suddenly slows, then just as inexplicably accelerates a short time later, only to slow again. As you keep adjusting to the leading car’s erratic speed changes, you sometimes find a clump of vehicles closely tailing […]

Pi à la Mode
A potential link between two disparate mathematical fields—number theory and chaotic dynamics—could lead to a proof that every digit of pi occurs with the same frequency.

Mozart’s Melody Machine
Music publishing was a thriving trade during the latter part of the 18th century in Europe. Publishers vied with one another to print the works of the latest “hot” composer. Many of them looked for novel ways to entice new customers into their music shops. One such ploy was to publish systems that would allow […]

Art of Pursuit
The simple mathematical concept of a pursuit curve can serve as the starting point for creating wonderfully intricate artistic designs. Four “bugs” chasing one another produce an intriguing pattern of nested, rotated squares. Courtesy of John Sharp. Pursuit curves based on a star-shaped polygon. Courtesy of John Sharp.
