The Power of the Perfect Right Angle: How Orthogonality Shapes Our World At the heart of how we map the physical world lies a simple but profound geometric rule: orthogonality. This principle ensures that the fundamental directions we use to describe a position—whether we are looking at a robotic arm or an atom—are always at perfect ninety-degree angles to one another. By verifying that these directions never "lean" into each other, we unlock a level of mathematical simplicity that makes modern technology and physics possible.
