Life's Ratchet by Peter M Hoffmann Pdf

Life is an enduring mystery. Yet, science tells us that living beings are merely sophisticated structures of lifeless molecules. If this view is correct, where do the seemingly purposeful motions of cells and organisms originate? In Life's Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale. Below the calm, ordered exterior of a living organism lies microscopic chaos, or what Hoffmann calls the molecular storm -- specialized molecules immersed in a whirlwind of colliding water molecules. Our cells are filled with molecular machines, which, like tiny ratchets, transform random motion into ordered activity, and create the "purpose" that is the hallmark of life. Tiny electrical motors turn electrical voltage into motion, nanoscale factories custom-build other molecular machines, and mechanical machines twist, untwist, separate and package strands of DNA. The cell is like a city -- an unfathomable, complex collection of molecular workers working together to create something greater than themselves. Life, Hoffman argues, emerges from the random motions of atoms filtered through these sophisticated structures of our evolved machinery. We are agglomerations of interacting nanoscale machines more amazing than anything in science fiction. Rather than relying on some mysterious "life force" to drive them -- as people believed for centuries -- life's ratchets harness instead the second law of thermodynamics and the disorder of the molecular storm. Grounded in Hoffmann's own cutting-edge research, Life's Ratchet reveals the incredible findings of modern nanotechnology to tell the story of how the noisy world of atoms gives rise to life itself.

The Big Ratchet by Ruth DeFries Pdf

How an ordinary mammal manipulated nature to become technologically sophisticated city-dwellers -- and why our history points to an optimistic future in the face of environmental crisis Our species long lived on the edge of starvation. Now we produce enough food for all 7 billion of us to eat nearly 3,000 calories every day. This is such an astonishing thing in the history of life as to verge on the miraculous. The Big Ratchet is the story of how it happened, of the ratchets -- the technologies and innovations, big and small -- that propelled our species from hunters and gatherers on the savannahs of Africa to shoppers in the aisles of the supermarket. The Big Ratchet itself came in the twentieth century, when a range of technologies -- from fossil fuels to scientific plant breeding to nitrogen fertilizers -- combined to nearly quadruple our population in a century, and to grow our food supply even faster. To some, these technologies are a sign of our greatness; to others, of our hubris. MacArthur fellow and Columbia University professor Ruth DeFries argues that the debate is the wrong one to have. Limits do exist, but every limit that has confronted us, we have surpassed. That cycle of crisis and growth is the story of our history; indeed, it is the essence of The Big Ratchet. Understanding it will reveal not just how we reached this point in our history, but how we might survive it.

Every Life Is on Fire by Jeremy England Pdf

A preeminent physicist unveils a field-defining theory of the origins and purpose of life. Why are we alive? Most things in the universe aren't. And everything that is alive traces back to things that, puzzlingly, weren't. For centuries, the scientific question of life's origins has confounded us. But in Every Life Is on Fire, physicist Jeremy England argues that the answer has been under our noses the whole time, deep within the laws of thermodynamics. England explains how, counterintuitively, the very same forces that tend to tear things apart assembled the first living systems. But how life began isn't just a scientific question. We ask it because we want to know what it really means to be alive. So England, an ordained rabbi, uses his theory to examine how, if at all, science helps us find purpose in a vast and mysterious universe. In the tradition of Viktor Frankl's Man's Search for Meaning, Every Life Is on Fire is a profound testament to how something can come from nothing.

The Canning Season by Polly Horvath Pdf

Love under trying circumstances One night out of the blue, Ratchet Clark's ill-natured mother tells her that Ratchet will be leaving their Pensacola apartment momentarily to take the train up north. There she will spend the summer with her aged relatives Penpen and Tilly, inseparable twins who couldn't look more different from each other. Staying at their secluded house, Ratchet is treated to a passel of strange family history and local lore, along with heaps of generosity and care that she has never experienced before. Also, Penpen has recently espoused a new philosophy – whatever shows up on your doorstep you have to let in. Through thick wilderness, down forgotten, bear-ridden roads, come a variety of characters, drawn to Penpen and Tilly's open door. It is with vast reservations that the cautious Tilly allows these unwelcome guests in. But it turns out that unwelcome guests may bring the greatest gifts. By turns dark and humorous, Polly Horvath offers adolescent readers enough quirky characters and outrageous situations to leave them reeling! The Canning Season is the winner of the 2003 National Book Award for Young People's Literature.

Brave Genius by Sean B. Carroll Pdf

The never-before-told account of the intersection of some of the most insightful minds of the 20th century, and a fascinating look at how war, resistance, and friendship can catalyze genius. In the spring of 1940, the aspiring but unknown writer Albert Camus and budding scientist Jacques Monod were quietly pursuing ordinary, separate lives in Paris. After the German invasion and occupation of France, each joined the Resistance to help liberate the country from the Nazis and ascended to prominent, dangerous roles. After the war and through twists of circumstance, they became friends, and through their passionate determination and rare talent they emerged as leading voices of modern literature and biology, each receiving the Nobel Prize in their respective fields. Drawing upon a wealth of previously unpublished and unknown material gathered over several years of research, Brave Genius tells the story of how each man endured the most terrible episode of the twentieth century and then blossomed into extraordinarily creative and engaged individuals. It is a story of the transformation of ordinary lives into exceptional lives by extraordinary events--of courage in the face of overwhelming adversity, the flowering of creative genius, deep friendship, and of profound concern for and insight into the human condition.

The Ratchet of Science by Roy Yorke Calne Pdf

Science, like the universe, is expanding and accelerating. This book outlines the many gifts that science has bestowed upon our quality of life ranging from health, travel, and communication, but it also raises concerns about the sometimes awful consequences of science. These may be accidental and unanticipated, or deliberate, as with the development of new weapons that carry dreadful potential. After the Second World War, a chasm separated the regimes of the East and West, and the possibility that the world was heading towards a catastrophic atomic conflict was a serious worry. Science has a responsibility for its consequences, even if these are not anticipated. In view of the history of science and our current relationship with scientific advances, it would be prudent to attempt a continuing peaceful dialogue to avoid future confrontation. For the writing of this book, the author made many in-depth studies of correspondence between scientists and philosophers, including, most notably, Albert Einstein and Bertrand Russell, at Churchill College Archives in Cambridge.

Conversations on the Dark Secrets of Physics by Wilson Talley,Wendy Teller Pdf

The idea for this book began over four decades ago when Edward Teller began teaching physics appreciation courses at the University of Chicago. Then, as now, Dr. Teller believes that illiteracy in science is an increasingly great danger to American society, not only for our chil dren but also for our growing adult population. On one hand, the future of every individual on this globe is closely related to science and its applications. Fear of the results of science, which has become prevalent in much of the Western World, leads to mistaken decisions in important political affairs. But this book speaks of no fears and of no decisions-only of the facts that can prevent one of them and indirectly guide the others. From the perspective of this book, a second point is even more vii viii PREFACE significant. The first quarter of this century has seen the most won derful and philosophically most important transformation in our thinking. The intellectual and aesthetic values of the points of view of Einstein and Bohr cannot be overestimated. Nor should they be hidden at the bottom of tons of mathematical rubble. Our young people must be exposed to science both because it is useful and because it is fun. Both of these qualities should be taken at a truly high value.

Life Finds a Way by Andreas Wagner Pdf

How the principles of biological innovation can help us overcome creative challenges in art, business, and science In Life Finds a Way, biologist Andreas Wagner reveals the deep symmetry between innovation in biological evolution and human cultural creativity. Rarely is either a linear climb to perfection--instead, "progress" is typically marked by a sequence of peaks, plateaus, and pitfalls. For instance, in Picasso's forty-some iterations of Guernica, we see the same combination of small steps, incessant reshuffling, and large, almost reckless, leaps that characterize the way evolution transformed a dinosaur's grasping claw into a condor's soaring wing. By understanding these principles, we can also better realize our own creative potential to find new solutions to adversity. Ultimately, Life Finds a Way offers a new framework for the nature of creativity, enabling us to better adapt, grow, and change in art, business, or science--that is, in life.
