a: Empirical formula ~
b: lowest common denominator
What: "an empirical formula is like the lowest common denominator. Eg CH3 is the empirical formula C2H6
is not - it is a molecular formula and as such has a specific mass. (in this case 30 g 2 x 12 + 1 x 6) C3H9 is also a molecular formula and has a mass of 45g (12 x 3 +1 x 9)"

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.
