John Emsley writes about chemistry for the lay person, but manages to bring to light facts and anecdotes that will delight chemists and chemical educators. What is "the worst smell in the world"? - and how is it used to protect us? What radioactive element is used in smoke detectors? What's the secret of Coca Cola? What chemical turns men on? Teachers of chemistry will find the names on many of the bottles in their storerooms in the fine Index in "Molecules at an Exhibition". This is a fun book to read!
