Multistability refers to a phenomenon where a system can exist in multiple stable states simultaneously. In psychology, this concept is often illustrated through visual perception, where an image can be interpreted in different ways, such as the famous Rubin's vase that can be seen as either a vase or two faces. In physics and engineering, multistability can occur in systems like mechanical structures or electronic circuits, where they can settle into different configurations under the same conditions. This property can be useful for designing systems that need to switch between states, enhancing functionality and adaptability.
