"Continuing the sandbag wall example, consider conduction of heat. Conduction is like the direct laying of bags on the wall by workers. Heat capacity is like the endurance of each worker - a high-endurance worker can keep working"
All these idea explain through cooking. A very informative article.
"Conduction is like a "relay" of thermal energy, occurring when neighboring molecules elastically collide with each other"
"Action potential conduction without myelin is like walking down the sidewalk in small steps, heel-to-toe, using every inch of the sidewalk to creep along. Conduction with myelin, is like skipping down the sidewalk. In myelinated axons, action potentials skip from node to node and this is called salutatory conduction."
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.
