Probe Vertically, See Horizontally
Excerpted from The Great Influenza by John M. Barry, © 2004:
The greatest challenge of science, its art, lies in asking an important question and framing it in a way that allows it to be broken into manageable pieces, into experiments that can be conducted that ultimately lead to answers. To this requires a certain kind of genius, one that probes vertically and sees horizontally.
Horizontal vision allows someone to assimilate and weave together seemingly unconnected bits of information. It allows an investigator to see what others do not see, and to make leaps of connectivity and creativity. Probing vertically, going deeper and deeper into something, creates new information. Sometimes what one finds will shine brilliantly enough to illuminate the whole world.
