:
Mnemonic symbol: the First Lady of the United States, FLOTUS.
In front of the anthill, Sun Wukong, the FLOTUS and Marie Curie dance around the golden calf. When it comes to be in favour of their gods, everyone of them wants to be first.

矢
:
Mnemonic symbol: Francis Bacon is attributed to have stated "scientia potentia est", "knowledge is power". I'll thus represent 知 by Francis Bacon. Francis Bacon (知) and James II of England (zh) are playing darts (矢) in front of the space station (Ø1). Because they lack a dart board they just use a mandarin (口).
