严于律己

严 = 亚 + 厂 : Mnemonic symbol: a tightly sealed bottling jar. Just inside the anthill's kitchen, Maud Younger is working on her top secret project. On a table she's got a sealed bottling jar of Mapo Doufu and a still packaged and sealed chocolate factory. She plans to modify the chocolate factory to produce Mapo Doufu, to sell the food world wide.

于 = 亅 + 二 : Mnemonic symbol: prepositions (in, at, on, to, ...) are what glue the sentence together. Honey is as sticky as glue, so I'll represent 于 by a honey jar.

Yu the Great (于) was assigned to repair the electronics of the space station's kitchen (Ø2), but instead he was snacking honey from a honey jar (于). Unfortunately his capacitor (二) got stuck in the honey and now he has to use a crowbar (亅) to lever it out.

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.

This character looks like a butcher's hook. In the space station, Joan of Arc wants to conduct an experiment about a sixth order chaotic pendulum. First she hooks a butcher's hook to a sickle, then sticks the sickle's end into a flute, and finally hooks the handle of a shovel into the last hole of the flute. She then swings the chaotic pendulum to observe its behaviour.
