- Sam Harris
Neuroscientist Sam Harris, the author of the bestselling The Moral Landscape (2010), here skewers the concept of free will — that mainstay of law, policy and politics — in fewer than 100 pages. Using evidence drawn from psychology and neuroscience, Harris asserts that the course of human life is all down to luck, and that willpower is a “biological phenomenon”. We are not in charge of our own minds, he says: thought and intention simply arise. This is a tract that is sure to boldly go straight to the heart of the determinism debate.
Why Calories Count: From Science to Politics
Marion Nestle and Malden Nesheim. University of California Press 304 pp. $19.95 (2012)
Obesity has gone global — as has misinformation about nutrition and food. Nutrition scientists Marion Nestle and Malden Nesheim unscramble the confusion with a serving of science. They reveal how calories — those potent but ill-understood measures of heat energy — are really counted, why we need them, how we use them, how many we actually need and why it all sometimes goes so wrong. From 'secret' calories to food politics, malnourishment and calorie restriction for health, this is a feast for the mind.
Born Believers: The Science of Children's Religious Belief
- Justin L. Barrett
Psychologist Justin Barrett says that belief is rooted not in indoctrination, but in a default setting of the infant brain. A range of findings in developmental psychology, he argues, support the theory: very young children, for instance, are aware that nature is not designed by humans; and people tend to look for unseen agents behind natural phenomena. Barrett says that the evidence points to a universal “natural religion” — but he also argues that parents must not impose belief systems on their children, and should leave the question of whether to die a believer up to their offspring.
Tinderbox: How the West Sparked the AIDS Epidemic and How the World Can Finally Overcome It
Daniel Halperin and Craig Timberg. Penguin 432 pp. $29.95 (2012)
The butchering of a chimpanzee in Cameroon about a century ago may have been when simian immunodeficiency virus crossed into humans and became HIV. But, argue epidemiologist Daniel Halperin and journalist Craig Timberg, European greed and technologies sparked the HIV pandemic. Trade routes, the growth of colonial cities, a decrease in male circumcision and a rise in prostitution effectively incubated and spread the disease — and Western programmes to curb it in Africa have proved mostly ineffectual, say the authors.
Digitized: The Science of Computers and How it Shapes Our World
- Peter J. Bentley
The wiring of the world — from a glint in Alan Turing's eye to global domination — is neatly encapsulated by computer scientist Peter Bentley. An enthusiastic guide, he lays this compelling history bare, explaining the science as he goes: Moore's law of processing-power growth, the circuit designs of Claude Shannon, John von Neumann's early electronic digital computer, neural networks and the staggering array of applications for computing in everything from pizza delivery to Alzheimer's-disease research.
