alkali earth metals
"The alkali earth metals are like slutty men. They're looking to give their electron to anyone willing to take it."
"The halogens are like slutty women. They're looking to get any electron they can."
"The noble gases are the prudes. They're happy the way they are and don't take shit from nobody."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
