time crystal
"A time crystal is like constantly oscillating jelly in its natural, ground state, and that's what makes it a whole new phase of matter - non-equilibrium matter. It's incapable of sitting still."
"A time crystal is like a spatial crystal that adds symmetry in the fourth dimension, in time as well as in space. Something that's symmetric in time is sort of like a clock: there's a repeating pattern of motion through time, and it's this pattern of motion that's analogous to the repeating pattern of atoms in space."
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.
