The Touchstone of Life: Molecular Information, Cell Communication, and the Foundations of Life
"If there were something like a guidebook for living creatures, I think the first line would read like a biblical commandment:Make thy information larger. And next would come the guidelines for colonizing, in good imperialist fashion, the biggest chunk of negative entropy around."Werner Loewenstein, a cell biologist at Woods Hole Biological Laboratories, has written a remarkably engaging book tying together information theory, thermodynamics, molecular biology, and the structure of cells. The subject is not one to which the human brain is well suited, but with Loewenstein's guidance you may get a better grasp on concepts like entropy than you've ever had before.Loewenstein describes life as a circus: "Flowing in from the cosmos, information loops back onto itself to produce the circular information complex we call Life.... To those who are inside the Circus, it will always seem the greatest show on Earth, though I can't speak for the One who is outside it."The Touchstone of Lifecovers some of the ground surveyed in Hofstadter'sGödel, Escher, Bachand Kauffman'sAt Home in the Universe, but with an even stronger sense of the physical realities constraining the "Circus." It should prove fascinating for anyone interested in biology, consciousness, physics, or the future of computing.--Mary Ellen Curtin
