規律性

规 = 夫 + 见 : In front of the Eiffel Tower, each year there are more and more surveillance cameras. A construction worker tries to find his way through this maze, but even his compass is of no use. However he's lucky that Gitta Giraffe is there: she's large enough to just see over the cameras to get an overview and tells the worker the way through the maze.

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.

性 = 忄 + 生 : Marie Curie had a strong character since she was little. Even in her cradle in the engine's bathroom she was only playing with a flail.
