beta decay
"Our physics professor made the analogy of these three decays into simple terms, where the grass is the substance in effect. Alpha decay is like a lawnmower on grass with much resistance and effect. Beta decay is like a golf ball on a green where it remains on path but gets slightly affected by the blades of grass with some resistance and interruption. A gamma decay is like the wind over the grass, moving it as it blows. These simple analogies given by my professor can be applied to the more precise scientific explanation that I told you to not to look to much into, instead think of the decays in the analogy terms."
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.
