Micro

by Michael Crichton

The more you watch, the more mysterious the natural world becomes, and the more you realize how little you know. Along with its beauty, you may also come to experience its fecundity, its wastefulness, aggressiveness, ruthlessness, parasitism, and its violence. These qualities are not well-conveyed in textbooks.

Perhaps the single most important lesson to be learned by direct experience is that the natural world, with all its elements and interconnections, represents a complex system and therefore we cannot understand it and we cannot predict its behavior.
