high energy photon
"That threshold energy is near the ultraviolet part of the electromagnetic spectrum, thousands of times more energetic than cell phone radio waves. UV, X-rays and gamma rays cause cancer. These photons are like golf balls, whereas radio photons are like cotton balls. You can throw millions of cotton balls against a window; it just won't break."
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.
