Review: Ubik by Philip K. Dick and The Langoliers by Stephen King
Those concerned about the world energy situation have long been preoccupied with the second law of thermodynamics and the concept of entropy. Entropy is a measure of the energy lost as waste heat whenever energy flows from higher concentrations to lower ones, as it always does when left to itself. An oft-cited example is the cooling of a cup of coffee left at room temperature. It’s a vital principle to grasp in thinking about energy resources, because it explains why the “replacements” for oil won’t cut it. In addition to its definition in physics, however, entropy also refers to how systems in general tend to wind down and become less complex over time. Indeed, Guardian columnist George Monbiot has called life itself “a struggle against entropy.”
