Science and the City: The Mechanics Behind the MetropolisCities are a big deal. More people now live in them than don't, and with a growing world population, the urban jungle is only going to get busier in the coming decades. But how often do we stop to think about what makes our cities work? Cities are built using some of the most creative and revolutionary science and engineering ideas – from steel structures that scrape the sky to glass cables that help us communicate at the speed of light – but most of us are too busy to notice. Science and the City is your guidebook to that hidden world, helping you to uncover some of the remarkable technologies that keep the world's great metropolises moving. Laurie Winkless takes us around cities in six continents to find out how they're dealing with the challenges of feeding, housing, powering and connecting more people than ever before. In this book, you'll meet urban pioneers from history, along with today's experts in everything from roads to time, and you will uncover the vital role science has played in shaping the city around you. But more than that, by exploring cutting-edge research from labs across the world, you'll build your own vision of the megacity of tomorrow, based on science fact rather than science fiction. Science and the City is the perfect read for anyone curious about the world they live in. |

These ingredients are then ground up, heated to temperatures above 1,450°C (around 2,640°F), and then ground again to a very fine powder. To make concrete, simply mix this with water and aggregate, et voilà!

Instead, they respond to environmental changes, such as light levels (photochromic), or temperature (thermochromic). If you've ever used adaptive sunglasses, you'll know that photochromic materials darken when you walk out into the sun.

If unchecked, temperature variations caused by the stack effect can cause structural problems too, so rotating doors really are rather useful. But for the skyscrapers of tomorrow, shouldn't we be able to make use of the stack effect?
