Download or read book The Ratchet of Science written by Roy Yorke Calne and published by Nova Science Publishers. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.
Download or read book Ratchetdemic written by Christopher Emdin and published by Beacon Press. This book was released on 2021-08-10 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: A revolutionary new educational model that encourages educators to provide spaces for students to display their academic brilliance without sacrificing their identities Building on the ideas introduced in his New York Times best-selling book, For White Folks Who Teach in the Hood, Christopher Emdin introduces an alternative educational model that will help students (and teachers) celebrate ratchet identity in the classroom. Ratchetdemic advocates for a new kind of student identity—one that bridges the seemingly disparate worlds of the ivory tower and the urban classroom. Because modern schooling often centers whiteness, Emdin argues, it dismisses ratchet identity (the embodying of “negative” characteristics associated with lowbrow culture, often thought to be possessed by people of a particular ethnic, racial, or socioeconomic status) as anti-intellectual and punishes young people for straying from these alleged “academic norms,” leaving young people in classrooms frustrated and uninspired. These deviations, Emdin explains, include so-called “disruptive behavior” and a celebration of hip-hop music and culture. Emdin argues that being “ratchetdemic,” or both ratchet and academic (like having rap battles about science, for example), can empower students to embrace themselves, their backgrounds, and their education as parts of a whole, not disparate identities. This means celebrating protest, disrupting the status quo, and reclaiming the genius of youth in the classroom.
Download or read book Life s Ratchet written by Peter M Hoffmann and published by Basic Books. This book was released on 2012-10-30 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Every Life Is on Fire written by Jeremy England and published by Basic Books. This book was released on 2020-09-15 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Wretched of the Earth written by Frantz Fanon and published by Penguin Modern Classics. This book was released on 2001 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frantz Fanon's seminal work on the trauma of colonization, The Wretched of the Earth made him the leading anti-colonialist thinker of the twentieth century. This Penguin Modern Classics edition is translated from the French by Constance Farrington, with an introduction by Jean-Paul Sartre. Written at the height of the Algerian war for independence from French colonial rule and first published in 1961, Frantz Fanon's classic text has provided inspiration for anti-colonial movements ever since, analysing the role of class, race, national culture and violence in the struggle for freedom. With power and anger, Fanon makes clear the economic and psychological degradation inflicted by imperialism. It was Fanon, himself a psychotherapist, who exposed the connection between colonial war and mental disease, who showed how the fight for freedom must be combined with building a national culture, and who showed the way ahead, through revolutionary violence, to socialism. Many of the great calls to arms from the era of decolonization are now of purely historical interest, yet this passionate analysis of the relations between the great powers and the 'Third World' is just as illuminating about the world we live in today. Frantz Fanon (1925-61) was a Martinique-born French author essayist, psychoanalyst, and revolutionary. Fanon was a supporter of the Algerian struggle for independence from French rule, and became a member of the Algerian National Liberation Front. He was perhaps the preeminent thinker of the 20th century on the issue of decolonization and the psychopathology of colonization. His works have inspired anti-colonial liberation movements for more than four decades.

Download or read book Brownian Ratchets written by David Cubero and published by Cambridge University Press. This book was released on 2016-01-11 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Illustrating the development of Brownian ratchets, from their foundations, to their role in the description of life at the molecular scale and in the design of artificial nano-machinery, this text will appeal to both advanced graduates and researchers entering the field. Providing a self-contained introduction to Brownian ratchets, devices which rectify microscopic fluctuations, Part I avoids technicalities and sets out the broad range of physical systems where the concept of ratchets is relevant. Part II supplies a single source for a complete and modern theoretical analysis of ratchets in regimes such as classical vs quantum and stochastic vs deterministic, and in Part III readers are guided through experimental developments in different physical systems, each highlighting a specific unique feature of ratchets. The thorough and systematic approach to the topic ensures that this book provides a complete guide to Brownian ratchets for newcomers and established researchers in physics, biology and biochemistry.

This book was released on 2013-06-29 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Physics of Living Systems written by Fabrizio Cleri and published by Springer. This book was released on 2016-10-08 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, physics in its many aspects (thermodynamics, mechanics, electricity, fluid dynamics) is the guiding light on a fascinating journey through biological systems, providing ideas, examples and stimulating reflections for undergraduate physics, chemistry and life-science students, as well as for anyone interested in the frontiers between physics and biology. Rather than introducing a lot of new information, it encourages young students to use their recently acquired knowledge to start seeing the physics behind the biology. As an undergraduate textbook in introductory biophysics, it includes the necessary background and tools, including exercises and appendices, to form a progressive course. In this case, the chapters can be used in the order proposed, possibly split between two semesters. The book is also an absorbing read for researchers in the life sciences who wish to refresh or go deeper into the physics concepts gleaned in their early years of scientific training. Less physics-oriented readers might want to skip the first chapter, as well as all the "gray boxes" containing the more formal developments, and create their own á-la-carte menu of chapters.
