ME Professor Reza Alam’s “Rolling Rings” Featured by the American Association for the Advancement of Science

ME Professor Reza Alam’s precent manuscript collaboration, “Terminal retrograde turn of rolling rings,” was featured in the American Association for the Advancement of Science’s Science Shot. The manuscript explains that “when a coin or disk spins, its edge circles in the same direction as its center, so it executes a wobbly spiral. A ring starts out making the same sort of spiral, but as it winds down the rotation of its center suddenly changes to opposite that of the edge, so that the ring follows an S-shaped path.”
