The long answer involves an incredible journey through neuroscience, our subconscious and the time-bending power of meditation. Living in the present may never feel the same. Ready for some more? Okay. Why isn't Pluto a planet? Why are dogs' noses wet? Why do hens cluck more loudly after laying an egg? What happens when one black hole swallows another? Do our fingerprints change as we get older? How young can you die of old age? And what is at the very edge of the Universe? Life is full of mind-bending questions. And, as books like What If? and Why Don't Penguins' Feet Freeze? have shown, the route to find each answer can take us on the weirdest and most wonderful journeys. How Long is Now? is a fascinating new collection of questions you never thought to ask, along with answers that will change the way you see everything.

    Updated to reflect all critical new developments in drug action and drug-disease interaction. This is the desert island book of all medical pharmacology - if you can own just one pharmacology book, this is it.

    The only rock we eat, salt has shaped civilization from the very beginning, and its story is a glittering, often surprising part of the history of humankind. A substance so valuable it served as currency, salt has influenced the establishment of trade routes and cities, provoked and financed wars, secured empires, and inspired revolutions.

    But two decades ago, real chemistry sets began to disappear as manufacturers and retailers became concerned about liability. ,em>The Illustrated Guide to Home Chemistry Experiments steps up to the plate with lessons on how to equip your home chemistry lab, master laboratory skills, and work safely in your lab. The bulk of this book consists of 17 hands-on chapters that include multiple laboratory sessions on the following topics:Separating Mixtures Solubility and Solutions Colligative Properties of Solutions Introduction to Chemical Reactions & Stoichiometry Reduction-Oxidation (Redox) Reactions Acid-Base Chemistry Chemical Kinetics Chemical Equilibrium and Le Chatelier's Principle Gas Chemistry Thermochemistry and Calorimetry Electrochemistry Photochemistry Colloids and Suspensions Qualitative Analysis Quantitative Analysis Synthesis of Useful Compounds Forensic Chemistry With plenty of full-color illustrations and photos, Illustrated Guide to Home Chemistry Experiments offers introductory level sessions suitable for a middle school or first-year high school chemistry laboratory course, and more advanced sessions suitable for students who intend to take the College Board Advanced Placement (AP) Chemistry exam. A student who completes all of the laboratories in this book will have done the equivalent of two full years of high school chemistry lab work or a first-year college general chemistry laboratory course. This hands-on introduction to real chemistry -- using real equipment, real chemicals, and real quantitative experiments -- is ideal for the many thousands of young people and adults who want to experience the magic of chemistry.

    E. Gordon's classic introduction to the properties of materials used in engineering answers some fascinating and fundamental questions about how the structural world around us works. Gordon focuses on so-called strong materials--such as metals, wood, ceramics, glass, and bone--explaining in engaging and accessible terms the unique physical and chemical basis for their inherent structural qualities. He also shows how an in-depth understanding of these materials' intrinsic strengths--and weaknesses--guides our engineering choices, allowing us to build the structures that support our society. This work is an enduring example of first-rate scientific communication. Philip Ball's introduction describes Gordon's career and the impact of his innovations in materials research, while also discussing how the field has evolved since Gordon wrote this enduring example of first-rate scientific communication.
