"When unstable radioactive minerals are trapped in a mineral, they begin to decay. The mineral is like a tiny hour glass collecting products of decay and can be age-dated. The rate of decay varies with the radioactive element but is a constant. As an element such as uranium decays, it may lose protons and thus its atomic number and chemical identity changes. The new element created by the radioactive decay is called a daughter element. For example: uranium, the parent, element spontaneously decays to lead, the daughter element."
"A mineral is like a pure chocolate bar. It is made up of the same substance all the way through. They are solids. A mineral is made up of crystals. Almost all minerals have straight edges and flat surfaces. Minerals have different colours,hardness and crystal forms. There are about 2000 types of minerals."
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.
