Book Description
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 Description
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.

Book Description
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.

Book Description
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.

"A book that is full of surprises...Triumphant enough to make readers cheer; touching enough to make them cry." —Kirkus, STARRED Review If only getting a new life were as easy as getting a new notebook. But it's not. It's the first day of school for all the kids in the neighborhood. But not for me. I'm homeschooled. That means nothing new. No new book bag, no new clothes, and no new friends. The best I've got is this notebook. I'm supposed to use it for my writing assignments, but my dad never checks. Here's what I'm really going to use it for: Ratchet's Top Secret Plan Turn my old, recycled, freakish, friendless life into something shiny and new. This Florida State Book Award gold medal winner is a heartfelt story about an unconventional girl's quest to make a friend, save a park, and find her own definition of normal.

Book Description
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.
