barrel of the laser
"The Nova laser at Livermore routinely produces fusion neutrons by subjecting materials to intense blasts of coherent light - but the Nova facility is as big as an aircraft hangar, and the barrel of the laser is like the trunk of a giant redwood tree laid on its side."
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.
