周期解

周 = ⺆ + 土 + 口 : Mnemonic symbol: a hula hoop. James II of England (zh) performs in front of the outhouse (ou1): he swings a hula hoop (周), juggles three mandarins (口) and balances a small heap of dirt (土) on his head. He cheated a little bit though, because he stapled the heap of dirt to his wig with a stapler (⺆).

期 = 其 + 月 : Recently the Queen of Hearts (qi) has become an astronomer. In front of the space station (Ø1) she sits on top of a watchtower (其) and watches the moon (月). From the moon's movement around the tower she wants to calculate its period and phase (期). She didn't consider though that not only the moon is orbiting around her, she is also orbiting the moon.

解 = 刀 + 牛 + 角 : Mnemonic symbol: acetone, in which anything can be dissolved.

Inside of the elevator (e3) Joan of Arc (ji) is dissolving a horn (角). A moment ago she cut the horn from the bull's (牛) head using a cleaver (刀). The bull is still shocked as he sees Joan of Arc dissolve (解) his horn in acetone (解).
