"Delta waves are comparatively the strongest signals that your brain produces but also the slowest. If the beta waves of a highly active mind are like a bunch of rapid, tiny ripples in a pond, delta waves are like the huge, slow wave of tides."
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.
