三北

三 = 一 + 二 : Mnemonic symbol: a 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 ants. Moreover, he's balancing on a Cartesian coordinate system (三). Unfortunately, only three (三) ants stop to watch the performance.

北 = 丬 + 匕 : A compass rose. In the Eiffel Tower, Beelzebub tries to build a compass. As a baseplate he uses a piece of wood, on which he sticks the north pike of a compass rose. On the south pike he balances a ladle, which is supposed to adjust itself to earth's magnetic field.
