有理数域

有 = 𠂇 + 月 : Mnemonic symbol: confetti.

In an act of revolution, with a pair of scissors (𠂇) Maud Younger (y) is cutting a paper moon (月) into tiny pieces in the outhouse's living room (ou3). There is (有) only confetti (有) left over.

理 = 王 + 里 : Li Qingzhao (li) and Martin Luther King (王) have the mission to find out the intrinsic order (理) and inner essence (理) of sunflowers (里) in the space station (Ø3). They grow a few sunflowers and care for them very meticulously, talking to them and everything.

数 = 娄 + 攵 : Sheldon Shrimp (shu) occupied a lunar mansion (娄) inside of the space station (Ø3) although he knows that it is to be torn down. Outside of his lunar mansion the construction (or rather destruction) workers are already counting (数) down from ten. When they count (数) zero, they will start taking down the whole thing with their sledgehammers (攵).

域 = 土 + 或 : Yu the Great (yu) and Osvaldo Farrés (或) have been working in the space station's bathroom (Ø4) for several days now. Their task is to classify different kinds of mud (土) and build a mud taxonomy (域). Most of the time they slack off and play games through the LAN (域) instead, though.
