"The input (before integration) is the flow rate from the tap.
Integrating the flow (adding up all the little bits of water) gives us the volume of water in the tank."
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.
