An accessible and hard-hitting look at the facts behind air pollution in everyday life. Take a deep breath. You'll do it 20,000 times a day. You assume all this air is clean; it's the very breath of life. But in Delhi, the toxic smog is as bad for you as smoking 50 cigarettes a day. Even a few days in Paris, London or Rome is equivalent to two or three cigarettes. Air pollution is implicated in six of the top ten causes of death worldwide, including lung cancer, heart disease, stroke, and dementia. Breathless gives us clear facts about air pollution in our everyday lives, showing how it affects our bodies, how much of it occurs in unexpected places (indoors, inside your car), and how you can minimise the risks. Rooted in the latest science, including real-time air-quality experiments in city streets and ordinary homes, it will allow you to make up your own mind about the risks and trade-offs of modern living - wherever in the world you are.

WINNER OF THE AMERICAN INSTITUTE OF PHYSICS BOOK AWARD Everything you ever wanted to know about the surprising science in your home. From the dust on your bookshelf to the rips in your jeans, Atoms Under the Floorboards takes you on a whistle-stop tour of the home, revealing the scientific answers to niggling questions like ... - Why can’t you cook your dinner with a smartphone? - Why can falling from a ladder hurt like a crocodile bite? - Why does your laptop get hot when its only moving part is the cooling fan? - Why can you see through windows but not through walls? - What’s the connection between a bike wheel, a suspension bridge and a wedding dress? It’s rock-solid science that holds your house up in a hurricane, floods it with light at night and keeps it toasty on a crisp winter’s morning. Surprisingly simple scientific ideas can also explain all those strange, baffling and sometimes downright irritating things you chance upon as you move around your home each day. Clearly explained throughout, and packed with facts, figures and fun, Atoms under the Floorboards answers all these questions and hundreds more – the perfect way to discover some seriously surprising science from the sofa.

There are many units with which to measure time, including seconds, hours, days, and even decades. Clocks and calendars make it easier to see time pass, but time is always moving even when we aren't measuring it. Beginning with the sundials of the ancient Egyptians, readers will learn much more than just how to measure time. Simple explanations of time zones and the inner workings of classic and modern timepieces accompany brief introductions to some of the greatest scientists to study time. Engaging questions and a hands-on activity guide them through this important math concept.

A 10-gallon hat demonstrates the idea of volume and aids readers in learning measurements. Other fun examples and cool facts will engage readers in learning this important math concept. With an introduction to the simple formula for finding volume, this book's colorful photographs and illustrations will guide readers through the ways length and height are tied to volume and the different units used to express this measurement. Whether solving for an exact volume or estimating, readers will learn about regular and irregular 3-D shapes, and reinforce their comprehension with a concluding hands-on activity.

Two objects can be the same size, but not the same weight. Readers will learn not just about pounds and ounces, but also about how density, gravity, and mass affect weight. Using colorful photographs and illustrations of ancient and modern scales, this book will engage readers with fun facts about how boats float and how weight is used to make cookies. Using a range of familiar animals, including 7-ton elephants and 8-pound cats, readers will enjoy relatable examples and a concluding activity in which they can use their new knowledge.
