二指

二 = 一 : Mnemonic symbol: a capacitor, because the two strokes remind me of the symbol in electrical drawings. Albert Einstein (Ø) is experimenting with a capacitor (二) in the space station's bathroom (Ø4). He finds that it's uncomfortable to discharge a capacitor using two flutes (一).

指 = 扌 + 旨 : James II of England (zh) received another imperial decree (旨) In the space station (Ø3). Because his finger (指) nails (指甲) are so long, he has to use a toy claw (扌) to open the letter. In the decree it is written that he shall cut his finger nails because they are the only human objects than can be seen from earth without visual aide.
