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).

极 = 及 + 木 : As Joan of Arc (ji) and Yuwen Huaji (及) pass over the north pole (及) at Christmas just inside the space station's entrance (Ø2) they decide to celebrate this moment by having a little contest.
