三氯氧磷

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.

氧 = 气 + 羊 : Maud Younger (y) gave the sheep (羊) a balloon (气) inside of the anglepod (ang3), but unfortunately it doesn't float because it is filled with oxygen (氧).
