"For the same reason you can shake a book, or drop it off a 10 story building, and none of the words come loose from the page. The transistors in a CPU (or any solid state device) are printed directly on the substrate."
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.
