James Lawrence Powell breaks new ground. His scholarship is deep, and his stories are well-written and enriched with human detail. Anyone with an interest in how science progresses will profit from reading this book. -- Spencer Weart, director emeritus of the Center for History of Physics of the American Institute of Physics, author of The Discovery of Global Warming Absorbing. Publishers Weekly This clear and well-written book offers four classic examples that show how science progresses-despite tough opposition, generally accepted ideas are often slowly replaced by newer, better ones. As an apocryphal medical school dean told incoming students: 'Half of what we will teach you in the next four years is wrong. The problem is that we don't know which half.' James Lawrence Powell's new title provides a lively look at how the sciences, in this case the geosciences, really work. -- Seth Stein, Northwestern University, author of Disaster Deferred: How New Science is Changing Our View of Earthquakes in the New Madrid Seismic Zone This is first-rate story telling, with heroes, villians, and the often-unexpected discoveries that created revolutions in our concept of the planet. -- David Morrison Skeptical Inquirer
