Fake attribution Memes

The perfect gift for that linear algebra enthusiast in your life! This mug features the eigenvalue equation (A - λI)x = 0, cleverly attributed to the fictional "Sir Roger Eigen" (a punny mashup of "eigenvalue" and a person's name). It's the mathematical equivalent of those fake Shakespeare quotes everyone puts on inspirational posters. Linear algebra nerds will either burst out laughing or have an existential crisis wondering if they missed an important mathematician in their studies. Either way, they'll be too distracted to notice you've stolen their coffee.
