"Compared to water:
amp is like the quantity of water flowing through a river. The Mississippy-Misoury has more "amps" than the creek that flows through the Bayou.
joule is like the total quantity of water we are considering. Lake Superior has more "joule" than Lake Ontario."
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.
