Linear algebra students know the pain! Diagonalizing matrices is that special hell where mathematical rigor meets existential dread. In theory, every matrix should be diagonalizable with the right approach. In practice? You're staring at a 4×4 monstrosity with complex eigenvalues at 2AM, questioning your life choices.
The beer represents that magical moment when you decide math can wait until tomorrow, and suddenly all matrices become "theoretically diagonalizable" if you're brave enough to make some... creative assumptions. Nothing solves non-diagonalizable matrices like liquid courage and deadline-induced hallucinations!
