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.

Using the modern home as a springboard, Atoms Under the Floorboards presents the fascinating and surprising scientific explanations behind a variety of common (and often entertainingly mundane) household phenomena, from gurgling drains and squeaky floorboards to rubbery custard and shiny shoes.Packed with facts and fun, each chapter focuses on the objects and processes familiar in everyday life and slowly unpicks the science behind them. For example, the chapter on how buildings work introduces static and dynamic forces in explaining why buildings (and their foundations) don''t sink into the ground and why skyscrapers don''t blow over in strong winds. The chapter on bicycles explores how "circles (better known as wheels) with a few flimsy bits of metal (spokes) stretched between them" are able to support your weight--and this leads into a discussion of compression, tension, and how gears work.After reading Atoms Under the Floorboards, you''ll never look at everyday objects the same way again.

This book is for students following a module in numerical methods, numerical techniques, or numerical analysis. It approaches the subject from a pragmatic viewpoint, appropriate for the modern student. The theory is kept to a minimum commensurate with comprehensive coverage of the subject and it contains abundant worked examples which provide easy understanding through a clear and concise theoretical treatment.
