"Mechanical energy is like money in the bank; part of it in a saving account (potential energy) and part in a normal account that you can use immediately (kinetic energy)."
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.
