Perk up your proofs with our “A mathematician is a machine for converting coffee into theorems” mug - a must-have for anyone who runs on logic and lattes. This gem of a quote comes from Hungarian mathematician Alfred Rényi, who originally said, “Ein Mathematiker ist eine Maschine, die Kaffee in Sätze verwandelt.” The punchline? In German, Sätze means both “sentences” and “theorems” - a perfect little wordplay nugget for the caffeine-fueled math brain. Whether you’re cracking codes, scribbling formulas, or just pretending to think really hard, this mug is your daily reminder that coffee isn’t just a beverage - it’s a theorem generator.
