"In the late 1950s Richard Feynman
issued a public challenge by offering
$1000 to the first person to create
an electrical motor "smaller than 1/64th
of an inch". Much to Feynman's consternation
the young man who met this challenge,
William McLellan, did so by investing
many tedious and painstaking hours building
the device by hand using tweezers and a microscope. 
McLellan's motor now sits in a display case at the 
California Institute of Technology and has long 
since ceased to spin." Pics from Caltech archives:
