"The electron microscope is like the monkey wrench on the garage wall: What you do with it is the important thing."
"The electron microscope is like an upside-down light microscope. The
radiation enters at top and the specimen is viewed at the bottom. The
principle is the same as in a light microscope in that a beam of radiation
is focused by condenser lenses through the specimen, and then the
image is magnified by further lenses."
"The electron microscope is like the light microscope; however, the "lens" is an electric coil generating an electromagnetic field."
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.
