A crystal to precipitate
Excerpted from The Great Influenza by John M. Barry, © 2004:
All real scientists exist on the frontier. Even the least ambitious among them deal with the unknown, if only one step beyond the unknown. The best among them move deep into a wilderness region where they know almost nothing, where the very tools and techniques needed to clear the wilderness, to bring order to it, do not exist. There they probe in a disciplined way. There a single step can take them through the he looking glass into a world that seems entirely different, and if they are at least partly correct their probing acts like a crystal to precipitate an order out of chaos, to create form, structure, and direction. A single step can also take one off a cliff.
