duality

Duality refers to a situation where two different frameworks or perspectives describe the same underlying reality, each highlighting different aspects. For example, in physics, light can be seen as both a wave and a particle, depending on how you look at it. In mathematics, duality shows that certain problems have equivalent counterparts that can sometimes be easier to solve. Essentially, duality reveals a hidden connection between two different views, allowing us to approach and understand problems from multiple angles, often leading to deeper insights.
