Definition
Orthogonality describes the state of being orthogonal, which means being at right angles or perpendicular. It's a concept often used in mathematics, computer science, and physics to describe independence or non-correlation. Think of the x, y, and z axes in a 3D graph 📈; they're all orthogonal to each other. Orthogonality ensures that changes in one aspect don't affect another, promoting modularity and simplicity. This is crucial for well-designed systems.
