Description
An exuberant exploration of why the stuff we use (mostly) works—and a celebration of the unsung engineers who ensure it does.
When a manufacturer offers a 10,000-mile warranty on a car or slaps a “bear-resistant” label on a camping cooler, what do we know about how trustworthy that promise is, and how it’s backed up? For the cooler, it’s Kobuk the Destroyer, the fiercest member of the Interagency Grizzly Bear Committee’s panel of product-testing bears: Gifted at cracking locks and foiling manufacturers, Kobuk and his fellow bears play a crucial role in keeping us (and our snacks) safe. For everything else—as journalist Alex Davies reveals in this freewheeling tour of the hidden work that keeps the modern world going, safely and dependably—we have test engineers, who imagine how anything and everything could go wrong, and fight back.
From echo-proof chambers to Formula 1 wind tunnels to airplane hangars turned torture labs, Davies takes readers behind the scenes of a workforce that combats contingency with equal parts analytical rigor and wild imagination. Armed with sixty-foot cannons that fire frozen chickens into jet engines, rocket sleds so fast they knock fillings out of teeth, and Lazy Susans for tasting hundreds of cups of tea a day, test engineers break it so you can buy it.
But failure is a stubborn opponent: The tsunami will overtop the dam, the chatbot will give bad advice, the bear will eat your sandwich. Test engineers don’t just prevent disaster; they limit its fallout and make peace with its reality by balancing risk against reward. In an age of climate crisis, run-amok tech, and eroding trust in public institutions, knowing how they do it—and how we might do the same—is more valuable than ever before.
Brimming with humor and insight, Kobuk the Destroyer is a celebration of human ingenuity and a deeply human story about uncertainty, resilience, and the art of making a fragile world a little more reliable.
Reviews
"[H]ighly entertaining. . . . Kobuk the Destroyer will teach you to anticipate problems and protect your plans . . . just like the professionals do—or else!" — Janelle Shane, author of You Look Like a Thing and I Love You
"When Alex Davies gets curious about a question, I follow him where he goes. This time, the adventure is the story of the people who push the world to its breaking point for the greater good. I can’t remember the last book I devoured this quickly, or the last writer whose company I enjoyed this much." — PJ Vogt, host of Search Engine
"Only a writer as good as Alex Davies could take a litany of failure?a chronicle of broken things?and turn it into a celebration of human ingenuity. Things fall apart, but Davies tells the story of the people who pick up the pieces, subject them to rigorous testing, and rebuild the world." — Adam Rogers, author of Full Spectrum
"[Kobuk the Destroyer] tak[es] us through the often rollicking and relentlessly inventive realm of test engineering—where industrious engineers give everything hell so the rest of us don’t have to. . . . [T]his book left me with fresh respect for the hidden heroes who make sure our world actually works." — Guru Madhavan, author of Wicked Problems
"Engaging, witty, and deeply insightful. . . . Alex Davies has a gift for making the complex, hidden work of test engineers accessible and exciting. . . . A brilliant and long overdue tribute." — Roma Agrawal, engineer and author of Nuts and Bolts
"Every day, we benefit from the creativity and curiosity of test engineers who reduce safety risks across transportation, health care, and every aspect of our lives. Alex Davies delivers an engaging and illuminating account of how these individuals make our world safer." — Mark Rosekind, former NASA scientist, NTSB member, and NHTSA chief
