    Chemistry will never be the same!

    So how does chemistry give rise to biology? What could have led the first replicating molecules up such a path? Now, developments in the emerging field of 'systems chemistry' are unlocking the problem. Addy Pross shows how the different kind of stability that operates among replicating molecules results in a tendency for chemical systems to become more complex and acquire the properties of life. Strikingly, he demonstrates that Darwinian evolution is the biological expression of a deeper, well-defined chemical concept: the whole story from replicating molecules to complex life is one continuous process governed by an underlying physical principle. The gulf between biology and the physical sciences is finally becoming bridged.

    

    • Mercury thermometers are prohibited on airplanes for a crucial reason.• Kryptonite bicycle locks are easily broken.“Things fall apart” is more than a poetic insight—it is a fundamental property of the physical world. Why Things Break explores the fascinating question of what holds things together (for a while), what breaks them apart, and why the answers have a direct bearing on our everyday lives.When Mark Eberhart was growing up in the 1960s, he learned that splitting an atom leads to a terrible explosion—which prompted him to worry that when he cut into a stick of butter, he would inadvertently unleash a nuclear cataclysm. Years later, as a chemistry professor, he remembered this childhood fear when he began to ponder the fact that we know more about how to split an atom than we do about how a pane of glass breaks.In Why Things Break, Eberhart leads us on a remarkable and entertaining exploration of all the cracks, clefts, fissures, and faults examined in the field of materials science and the many astonishing discoveries that have been made about everything from the explosion of the space shuttle Challenger to the crashing of your hard drive. Understanding why things break is crucial to modern life on every level, from personal safety to macroeconomics, but as Eberhart reveals here, it is also an area of cutting-edge science that is as provocative as it is illuminating.“An engaging personal account not just of the physics and chemistry of materials but of the ethics, economics, and politics of innovation, with delightful bonuses on topics from the origins of ‘ghostly’ noises in old houses to the amazing coevolution of armor and armor-piercing projectiles. If it ain’t broke, Mark Eberhart can tell you why—and explain equally well why a shatterproof world remains beyond our reach.”—Edward Tenner, author of Our Own Devices and Why Things Bite Back“I don’t remember a book that has taught me so much, nor previously encountering a teacher like the marvelous Mark Eberhart, who in Why Things Break provides enlightening and thoroughly captivating scientific explanations of subjects ranging from the structural failures leading to the sinking of the Titanic to everyday, no-less-fascinating topics such as the reason why, even at the same temperature, winter days always seem so much colder in Boston than in Denver.”—Richard Restak, M.D., author of Mozart’s Brain and The Fighter Pilot“Eberhart brings his insights to the reader by weaving personal anecdotes—from his childhood fear that cutting a stick of butter would release the energy of the atoms within to his arrival in Boston for an interview with MIT without a suitable winter coat—into a fascinating discussion of the forces that hold atoms and molecules together. A lively, unvarnished look at chemistry on the cutting edge.” —Kirkus Reviews

    Chapter topics include atomic structure, molecular orbitals, organometallic chemistry, simple bonding theory, symmetry and group theory, and more. For chemists and other professionals who want to update or improve their background in the field.

    Known for its carefully developed, thoroughly integrated, step-by-step approach to problem solving, General Chemistry helps students master quantitative skills and build a lasting conceptual understanding of key chemical concepts.

    I have taught these simple processes to men and women all over the world, and recently over a thousand men and women of all religious affiliations attended a special class in Los Angeles where I presented the highlights of what is offered in the pages of this book. Many came from distances of two hundred miles for each class lesson. The special features of this book will appeal to you because they show you why oftentimes you get the opposite of what you prayed for and reveal to you the reasons why. People have asked me in all parts of the world and thousands of times, ?Why is it I have prayed and prayed and got no answer?? In this book you will find the reasons for this common complaint. The many ways of impressing the subconscious mind and getting the right answers make this an extraordinarily valuable book and an ever present help in time of trouble.

    For outsiders, Pyrrus usually means a quick and painful death, but DinAlt is fleeing the crooked casino masters of Cassylia - where he just broke the bank.

Using his skills, DinAlt literally reinvents the wheel in his quest to escape and return to his friends on Pyrrus.

    

    Its tale is one riddled with jealousy, rivalry, missed opportunities and moments of genius. Piers Bizony tells the story of the young misfit New Zealander, Ernest Rutherford, who showed that the atom consisted mainly of empty space, a discovery that turned 200 years of classical physics on its head, and the brilliant Dane, Niels Bohr, who made the next great leap into the incredible world of quantum theory. Yet he and a handful of other Young Turks in this revolutionary new science weren't prepared for the shocks that Nature had up her sleeve. At the dawn of the Atomic Age, a dangerous new force was unleashed with terrifying speed...

    The nature of football continually changes, which means its analysis must also keep pace. This book is for students, thinkers, and theorists of the game.'Ted Hopkins - Carlton premiership player, author, and co-founder of Champion Data. Australian Rules football has been described as the most data-rich sport on Earth. Every time and everywhere an AFL side takes to the field, it is shadowed by an army of statisticians and number crunchers. The information they gather has become the sport's new language and currency. ABC journalist James Coventry, author of the acclaimed Time and Space, has joined forces with a group of razor-sharp analysts to decipher the data, and to use it to question some of football's long-held truisms. Do umpires really favour the home side? Has goal kicking accuracy deteriorated? Is Geelong the true master of the draft? Are blonds unfairly favoured in Brownlow medal voting? And are Victorians the most passionate fans? Through a blend of entertaining storytelling and expert analysis, this book will answer more questions about footy than you ever thought to ask. Praise for Time and Space:'Brilliant, masterful' - The Guardian'Arguably one of the most important books yet written on Australian Rules football.' - Inside History'Should find its way into the hands of every coach.' - AFL Record

    Everyone everywhere now carries a dizzying array of chemical contaminants, the by-products of modern industry and innovation that contribute to a host of developmental deficits and health problems in ways just now being understood. These toxic substances, unknown to our grandparents, accumulate in our fat, bones, blood, and organs as a consequence of womb-to-tomb exposure to industrial substances as common as the products that contain them. Almost everything we encounter?from soap to soup cans and computers to clothing?contributes to a chemical load unique to each of us. Scientists studying the phenomenon refer to it as ?chemical body burden,? and in The Body Toxic, the investigative journalist Nena Baker explores the many factors that have given rise to this condition?from manufacturing breakthroughs to policy decisions to political pressure to the demands of popular culture. While chemical advances have helped raise our standard of living, making our lives easier and safer in many ways, there are costs to these conveniences that chemical companies would rather consumers never knew about. Baker draws back the curtain on this untold impact and assesses where we go from here.

    In 1905 an unknown 26-year-old clerk at the Swiss Patent Office, who had supposedly failed math in school, burst on to the scientific scene and swept away the hidebound theories of the day. The clerk, Albert Einstein, introduced a new and unexpected understanding of the universe and launched the two great revolutions of twentieth-century physics, relativity and quantum mechanics. The obscure origin and wide-ranging brilliance of the work recalled Isaac Newton’s “annus mirabilis” (miracle year) of 1666, when as a 23-year-old seeking safety at his family manor from an outbreak of the plague, he invented calculus and laid the foundations for his theory of gravity. Like Newton, Einstein quickly became a scientific icon--the image of genius and, according to Time magazine, the Person of the Century.The actual story is much more interesting. Einstein himself once remarked that “science as something coming into being ... is just as subjectively, psychologically conditioned as are all other human endeavors.” In this profile, the historian of science L. Randles Lagerstrom takes you behind the myth and into the very human life of the young Einstein. From family rifts and girlfriend troubles to financial hardships and jobless anxieties, Einstein’s early years were typical of many young persons. And yet in the midst of it all, he also saw his way through to profound scientific insights. Drawing upon correspondence from Einstein, his family, and his friends, Lagerstrom brings to life the young Einstein and enables the reader to come away with a fuller and more appreciative understanding of Einstein the person and the origins of his revolutionary ideas.About the cover image: While walking to work six days a week as a patent clerk in Bern, Switzerland, Einstein would pass by the famous "Zytglogge" tower and its astronomical clocks. The daily juxtaposition was fitting, as the relative nature of time and clock synchronization would be one of his revolutionary discoveries in the miracle year of 1905.
