All your settings, pendulum configuration, notes, todos, widgets, and preferences are automatically saved and synchronized across all tabs and devices in real-time. When you open multiple tabs, they all display the exact same pendulum state in perfect synchronization. Your configuration persists across browser sessions and adapts perfectly to different window sizes.

The double pendulum is one of the simplest systems that exhibits chaotic behavior. Despite having only two moving parts, its motion is highly sensitive to initial conditions - a hallmark of chaos theory.
