Most people are familiar with Albert Einstein's famous "Theory of Relativity" and his equation that states that E=MC2 (even if they don't know that it means that energy is equal to mass times the square of the speed of light, but I digress). Less famous, though equally as important, is Einstein's "Theory of Musical Relativity" and his equation that E=Fb (or E is equal to F flat).
Whether you're a musician (or music lover) who is into science, or a scientist who appreciates music, this tongue-in-cheek and slightly surreal design is perfect for you!
