Context Matters

a: Electrode ~
b: golf ball

What: "Frequently customers ask me how tight their pH measurement is. I make an analogy: An electrode is like a golf ball. How close you get to the target depends upon the expertise of the golfer, the quality of his equipment and the environmental conditions. The same goes for pH measurements. Repeatability or precision matters more than accuracy for most processes, but ultimately depends on the operator and the process."

In Batteries That Is....

a: Electrode ~
b: a piece of foil

What: "Traditionally, flat-stacked batteries have been difficult and expensive to produce. "An electrode is like a piece of foil, but thinner than what you use in the kitchen," explains Feaver. "The separator is even thinner yet and can behave like the kitchen plastic wrap you use to cover bowls, sticking to itself or wrinkling. In a cell, the electrodes and separator must be aligned very precisely, which is exceedingly difficult and time- consuming with these thin materials."

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.
