晝夜節律

昼 = 尺 + 旦 : During the daytime (昼) James II of England (zh) measures the time by measuring how much coffee is left in his coffee mug (旦) with a tape measure (尺). He has the habit of doing so in the outhouse's bathroom (ou4).

夜 = 亠 + 亻 + 丶 + 夂 : Mnemonic symbol: 夜壶, chamber pot.

In the middle of the night, Maud Younger and Rosa Luxemburg bump into each other as they are emptying their chamber pot in the elevator's bathroom. They covered their chamber pots with a petal leaf and a beret respectively, and as they carry them they take care to walk very slowly in their high heels.

节 = 卩 + 艹 : Joan of Arc and the baby seal spend their holiday just inside the elevator's kitchen. They are relaxing on artificial lawn camp beds all day.

律 = 彳 + 聿 : Loki (lü) wants to prove the inverse square law (律) of electrostatics in the space station's bathroom (Ø4). He repeatedly rubs a decorator's brush (聿) against the soles of his black sneakers (彳) and thereby transfers electrons from the shoe soles to the brush. Now that both are charged, they will attract each other according to the inverse square law (律). To measure the amplitude, Loki uses Hook's law (律): when the black sneaker is attracted to the brush it will bend the bristles of the brush until the two forces cancel each out.
