"[Our philosopher] asserted that he knew the whole secret...[H]e surveyed the two celestial strangers from top to toe, and mantained to their faces that their persons, their worlds, their suns and their stars, were created solely for the use of man. At this assertion our two travelers let themselves fall against each other, seized with a fit of...inextinguishable laughter"
-- Voltaire (1752)

Nanowires that Emit UV Light | National Institute of Standards and Technology
NIST “grows” semiconductor nanowires that emit ultraviolet light as part of a project to make prototype nano-lasers and other devices and the measurement tools needed to characterize them. Electron micrograph shows the gallium nitride wires growing on a silicon substrate (color added for contrast.)
