A tiny mote of dust is truly a cosmos unto itself, that much we do now know. It contains molecules that are far too small for us to see without a microscope, but they are no less real than the dust itself or the piano on which the mote of dust has settled.
-- Roger A. Caras, Cat Is Watching
A white mote hovered in the air several feet away from her.
-- Sara Stern, Dragon's Song
Mote stems from the Norwegian word mutt meaning "a speck."
