学而不思则罔，思而不学则殆

学 = 小 + 冖 + 子 : Xu Xian wants to study scienceology and learn more about daisies. Just inside the elevator's kitchen, he put some daisies into a prize cup and covered them with a cooking top. He wants to study the growth rate of the daisies depending on the pH of the water in the prize cup.

而 = 𦉫 + 丆 : A comb. Albert Einstein is getting ready to go out just inside the entrance of the space station. He put up some loud music on the stereo and tries to comb his hair with his comb and the help of a wind wheel.

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.

思 = 心 + 田 : Socrates is feeling blue in front of the space station. He's thinking of burying his heart under a field. When he finishes, he realizes that he has created some kind of small planet, with his heart at the center.

则 = 刂 + 贝 : Mnemonic symbol: 武则天 (Wu Zetian), the only female emperor of China in more than four millennia. It makes sense because for sure she wrote many official statements, for which 则 is the classifier.

则 = 刂 + 贝 : Just inside the elevator's kitchen, Zorro found a crab. He already has a kitchen knife in his hand and wants to kill and eat the crab, but Wu Zetian quickly writes an official rule that forbids the eating of crabs, much to Zorro's disappointment.
