Science is integral to our everyday lives, but can you explain the scientific principle at work when you squeeze lemon on your fish? Did you know that margarine may be dangerous, humans are radioactive because of the foods they eat, special viruses can be useful antibiotics, and water vapour is the major gas involved in global warming? Full of surprising anecdotes, curious facts and historical oddities, this book connects observations from our everyday lives to the scientific principles that explain them. You will find information on organic and commercial foods, natural herbs, modern medicine, the environment, DNA testing, and much more. The author has avoided scientific jargon and mathematics to make this book of interest to non-scientists and scientists alike.
