Orthogonality Memes

The forbidden love story between i-hat and j-hat, the unit vectors of coordinate systems everywhere. One's a simple (1,2) while the other's a complicated (2,50) - talk about dating outside your orthogonal basis! Their relationship will never work because they're not perpendicular to each other. The cross product of their love would yield a vector pointing in some weird direction that makes mathematicians uncomfortable. This is what happens when vectors ignore the fundamental rules of orthonormality!
