Have you ever asked yourself how the inventions, gadgets, and devices that surround us actually work? Discover the hidden workings of everyday technology with this graphic guide. How Technology Works demystifies the machinery that keeps the modern world going, from simple objects such as zip fasteners and can openers to the latest, most sophisticated devices of the information age, including smartwatches, personal digital assistants, and driverless cars. It includes inventions that have changed the course of history, like the internal combustion engine, as well as technologies that might hold the key to our future survival, including solar cells and new kinds of farming to feed a growing population. Throughout the book, step-by-step explanations are supported by simple and original graphics that take devices apart and show you how they work. The opening chapter explains principles that underpin lots of devices, from basic mechanics to electricity to digital technology. From there, devices are grouped by application--such as the home, transportation, and computing--making them easy to find and placing similar devices side by side. How Technology Works is perfect for anyone who didn't have training in STEM subjects at school or is simply curious about how the modern world works.

Presents some of the characteristics of inventors by describing the inventions of people such as Alexander Graham Bell, Thomas Edison, and Eli Whitney.

A systematic investigation of growth in nature and society, from tiny organisms to the trajectories of empires and civilizations. Growth has been both an unspoken and an explicit aim of our individual and collective striving. It governs the lives of microorganisms and galaxies; it shapes the capabilities of our extraordinarily large brains and the fortunes of our economies. Growth is manifested in annual increments of continental crust, a rising gross domestic product, a child's growth chart, the spread of cancerous cells. In this magisterial book, Vaclav Smil offers systematic investigation of growth in nature and society, from tiny organisms to the trajectories of empires and civilizations. Smil takes readers from bacterial invasions through animal metabolisms to megacities and the global economy. He begins with organisms whose mature sizes range from microscopic to enormous, looking at disease-causing microbes, the cultivation of staple crops, and human growth from infancy to adulthood. He examines the growth of energy conversions and man-made objects that enable economic activities—developments that have been essential to civilization. Finally, he looks at growth in complex systems, beginning with the growth of human populations and proceeding to the growth of cities. He considers the challenges of tracing the growth of empires and civilizations, explaining that we can chart the growth of organisms across individual and evolutionary time, but that the progress of societies and economies, not so linear, encompasses both decline and renewal. The trajectory of modern civilization, driven by competing imperatives of material growth and biospheric limits, Smil tells us, remains uncertain.
