The random motion of a hydrogen molecule can drive the
oscillation of a much larger structure
A single hydrogen molecule just might be a real-life little
engine that could, according to a new study. It would be hard to imagine an
engine much tinier.
Physicists in Germany and Spain have demonstrated that a
hydrogen molecule dancing between two possible positions can induce regular
vibration of a nearby cantilever—essentially a miniature tuning fork made of
quartz.
