The Science of Accidental Discoveries: 197

Human progress is usually presented as a dignified parade of brilliant people asking intelligent questions, conducting careful experiments, and emerging from laboratories with neatly labeled solutions. That version looks excellent in textbooks. It is also suspiciously incomplete. A remarkable portion of civilization was built by people who contaminated their experiments, forgot what they were doing, dropped things, misunderstood instructions, left equipment running, noticed something peculiar in the trash, or investigated a result that any sensible person might have quietly hidden before the supervisor arrived.Accidental discovery does not mean that knowledge simply falls out of the ceiling and lands in the lap of the nearest confused scientist. The accident creates an opportunity, but someone still has to recognize that the mistake is interesting. Millions of people have burned food, spoiled mixtures, broken equipment, and left questionable substances unattended without receiving a Nobel Prize. The important difference is that a discoverer pauses before cleaning up the mess and asks, "Why did that happen?" This is the scientific method's less respectable cousin: observation followed by curiosity, mild alarm, and a firm request that nobody throw anything away.
