This is a follow-up of sorts to Theodore Gray's earlier book, The Elements: A Visual Exploration of Every Known Atom in the Universe. Unlike that one, this volume cannot possibly be comprehensive because while there are a limited number of elements in the periodic table, the ways in which those elements can combine into molecules is practically infinite. So Gray instead takes us through a sampling of interesting and important molecules, loosely organized by what they're used for by human beings. If you've read The Elements -- and you should! -- this one has a very similar sensibility, with lots and lots of photos of substances the author has painstakingly collected and managed to make visually interesting, despite the tendency of most pure substances to actually just look like boring white powders. There's a nice little basic chemistry lesson at the beginning and all kinds of wonderfully fascinating information to be found throughout the entire book, as Gray tells us, for instance, why teflon is so slippery, how soap works, why oil and water don't mix, and what's in artificial sweeteners, along with tons of other, sometimes much weirder and more obscure things. He does this with a lot of genial humor; in places this book is genuinely laugh-out-loud funny. But he also takes a wonderfully hard-headed and clear-eyed look at things like what the difference is between "natural" and "artificial" substances is (answer: very little), at chemicals that get an undeserved bad rap, and at ones that genuinely are bad news. It's all extremely interesting and delightfully fun, as weird as that might seem for a book about chemistry, even for a science-minded reader like me. More than that, though, I think it really has shifted my perspective on the world around me. It's one thing to be aware, hypothetically, somewhere in the back of your mind, that everything in the world is made of molecules and almost everything that happens in it comes down to the action of these small, varied entities fitting together and breaking apart, but it's a different experience entirely to find yourself stopping to think about what that really means, and to marvel at the ways in which we human beings have found to shape these tiny interactions to do some very big things. And all the more so when you contemplate just how simple so many of these ultra-important molecules are, and how much small differences between them -- even ones so small it can be hard to notice them on a diagram -- matter in our lives. In other words, this is pretty, it's entertaining, it's educational, and it's actually kind of mind-blowing. A very, very cool book! The p-book is truly beautiful, but the iPad version of the book is remarkable! You can play around with the jiggling molecules in 3D, while the app is presenting all the text from the book illustrated by interactive animations. One of the rare examples of a book vastly improved, not degraded by "appification". aucune critique | ajouter une critique

Gray begins with an introduction about the electrostatic force that holds compounds together in a single atom as well as in compounds and molecules. He reviews the architecture of atoms which is key to how they can combine. Then he goes into specifics.
Chapter 2 is a riff on alchemical names, and an explanation for many of named categories, like salts, acids, alcohols, aldehydes, ketones, etc. Chapter 3 explains the distinction between organic and inorganic compounds, or as he calls it, “Dead or Alive.” Chapter 4 uses the relationship between oil and water to discuss bonds between atoms and what that means for molecules. In particular he focuses on “the magic of soap” and tells readers how soap works. Chapter 5 tackles the difference between compounds that are “mineral” and those that are “vegetable” - oil and wax are the main topics of this chapter. Chapter 6 moves onto rock and ore. Chapter 7 is for rope and fiber - what they are made of and how they work, including a section on animal-made fibers. The most widely used animal fibers, he avers, come from “soft and warm animals such as sheep and fluffy birds.” What are they made of and why are they warm? In Chapter 8, the author writes about “Pain and Pleasure” and the molecular make-up of what compounds that cause pain in the body and compounds that relieves it. Chapter 9, “Sweet and Double Sweet” relates to sugars and sugar substitutes. (Stevia packets, you might be interested to know, are 96 percent glucose sugar, with only 4 percent made up of stevia extract.). In Chapter 10, Gray expands on the distinctions between natural and artificial compounds. Chapter 11 deals with scent, or “molecules as messengers.” Chapter 12 explores the colors of molecules and how they come to be. The 13th chapter is called “I Hate That Molecule.” Here the author writes about compounds that have been caught up in politics, such as those comprising vaccines. He addresses the controversy about vaccines containing thimerosal, for example, and notes: “The number of children who developed autism as a result of being given vaccines containing thimerosal is [easy] to determine: it is known to be exactly zero.” He also deals with compounds containing lead, affecting the ozone layer, contributing to global warming, and causing disease - he calls asbestos “The Most Horrible Very Bad Inorganic Compound Ever.” Finally, Chapter 14 deals with the molecules that “run the machinery of life” DNA and RNA.
All of these facts, fun as they are, are secondary to the visual aspects of the book, in which amazing large color photos (by both Theodore Gray and Nick Mann) of both the molecules and products derived from them make up the bulk of the presentations.
Evaluation: If you ever thought chemistry was “boring,” you are in for a surprise and an intellectual and visual treat. This book is outstanding, and will stimulate your desire to know more about molecules, and how people figured out how to use them. ( )
