"Temp difference in thermal conductivity is like pressure difference in fluids or potential difference in electricity! -> Rate of heat flow is like volume flow rate or current.
(ΔT = IR, ΔP = QR, ΔV = iR) -> in all cases, thicker conduits allow greater flow, longer conduits impede flow, and flow rate depends upon difference in a property of the reservoirs at either end of conduit."
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.
