Magnetically Speaking

a: Atoms ~
b: spinning tops

What: "Atoms are like spinning tops. They have an internal angular momentum J. As most physical quantities, the projection Jz of J along the z-axis is quantized : Jz = M h, where h = h/(2π) and where M is an integer or half-integer, positive or negative."

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.
