"Viscosity is like a gooeyness factor. Imagine the difference between water and syrup. Syrup is more viscous than water. It's harder to run your fingers through syrup than water, right? "
"Longest flow time Viscosity is like "resistance" for liquids. Since C had the longest flow time, its molecules must be "stuck" (strongly bonded) to each other."
"Viscosity is like the internal friction of a fluid. Liquids flow fastest in the center and tend to zero as the wall of the pore is approached."
"A chemical engineer I worked for explained it like this - the molecular structure is like a licorice stick or a DNA molecule - twisted. As the oil heats up, those additive molecules start to unwind & get longer - they'll twist back tighter & get shorter as the oil cools down. But if the oil gets too hot, the molecular structure just falls apart & you can't put it back together again. "
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.
