三 = 一 + 二 : Mnemonic symbol: Cartesian coordinate system with three (三) axes. Socrates (s-) is performing in front of the anthill (-an1). He created an electrical flute by attaching a large capacitor (二) to the flute (一), so that he can get the attention of all the people. Moreover, he's balancing on a Cartesian coordinate system (三).
