Eigenvalues and Eigenvectors in Matrix Diagonalization
Quick fact
Not every matrix can be diagonalized; only those that are 'diagonalizable' have enough linearly independent eigenvectors to form a full basis.
Why this is interesting
Imagine watching a movie where the hero is trapped in a funhouse of mirrors—every movement gets twisted and stretched. But what if you could turn the funhouse into a simple elevator, moving only along clean, straight lines?
