二度

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).

度 = 又 + 广 + 廿 : Mnemonic symbol: a thermometer.

度 = 又 + 广 + 廿 : Doggy Dog follows a rigid training plan in the space station's bathroom to spend his time, even though he is sick and has a fever. To measure the degree of intensity of his fever, he uses a thermometer to measure his temperature. Even while doing this he still boxes a flower pot (which he suspended from a parachute) with his boxing glove.
