An Aston University researcher has conducted the first experimental demonstration of intricate and previously theorized behaviors in the fundamental patterns that govern oscillatory systems in nature and technology.

Synchronization regions, also known as Arnold’s tongues because of the shape they take when shown on a graph, help scientists understand when things will stay in sync and when they won’t.

Arnold’s tongues are observed in a large variety of natural phenomena that involve oscillating quantities, such as heartbeats, pendulum swings or flashing lights.
