As We May Think
by Vannevar Bush
As Director of the Office of Scientific Research and Development, Dr. Vannevar Bush has
coordinated the activities of some six thousand leading American scientists in the application
of science to warfare. In this significant article he holds up an incentive for scientists when the
fighting has ceased. He urges that men of science should then turn to the massive task of making more accessible our bewildering store
of knowledge. ...
