Now delete that picture. In Once Upon an Algorithm, Martin Erwig explains computation as something that takes place beyond electronic computers, and computer science as the study of systematic problem solving. Erwig points out that many daily activities involve problem solving. Getting up in the morning, for example: You get up, take a shower, get dressed, eat breakfast. This simple daily routine solves a recurring problem through a series of well-defined steps. In computer science, such a routine is called an algorithm.Erwig illustrates a series of concepts in computing with examples from daily life and familiar stories. Hansel and Gretel, for example, execute an algorithm to get home from the forest. The movie Groundhog Day illustrates the problem of unsolvability; Sherlock Holmes manipulates data structures when solving a crime; the magic in Harry Potter's world is understood through types and abstraction; and Indiana Jones demonstrates the complexity of searching. Along the way, Erwig also discusses representations and different ways to organize data; "intractable" problems; language, syntax, and ambiguity; control structures, loops, and the halting problem; different forms of recursion; and rules for finding errors in algorithms.This engaging book explains computation accessibly and shows its relevance to daily life. Something to think about next time we execute the algorithm of getting up in the morning.

    For the engineers who had to kill the well, this was like Apollo 13, a crisis no one saw coming, and one of untold danger and challenge. A suspense story, a mystery, a technological thriller: This is Joel Achenbach’s groundbreaking account of the Deepwater Horizon disaster and what came after. The tragic explosion on the huge drilling rig in April 2010 killed eleven men and triggered an environmental disaster. As a gusher of crude surged into the Gulf’s waters, BP engineers and government scientists—awkwardly teamed in Houston—raced to devise ways to plug the Macondo well. Achenbach, a veteran reporter for The Washington Post and acclaimed science writer for National Geographic, moves beyond the blame game to tell the gripping story of what it was like, behind the scenes, moment by moment, in the struggle to kill Macondo. Here are the controversies, the miscalculations, the frustrations, and ultimately the technical triumphs of men and women who worked out of sight and around the clock for months to find a way to plug the well. The Deepwater Horizon disaster was an environmental 9/11. The government did not have the means to solve the problem; only the private sector had the tools, and it didn’t have the right ones as the country became haunted by Macondo’s black plume, which was omnipresent on TV and the Internet. Remotely operated vehicles, the spaceships of the deep, had to perform the challenging technical ma-neuvers on the seafloor. Engineers choreographed this robotic ballet and crammed years of innovation into a single summer. As he describes the drama in Houston, Achenbach probes the government investigation into what went wrong in the deep sea. This was a confounding mystery, an engineering whodunit. The lessons of this tragedy can be applied broadly to all complex enterprises and should make us look more closely at the highly engineered society that surrounds us. Achenbach has written a cautionary tale that doubles as a technological thriller.

    He would return in September. For the next ten weeks my survival would depend on foraging, hunting and fishing on an island I would share with 1,600 brown bears. This is my story of hunger and solitude, salmon fishing and stormy seas, torrential rains and mountain sunsets, giant halibut and deer hunting, campfires and killer whales. Illustrated with nearly fifty photos and a map.
