Book Description
Life, Hoffman argues, emerges from the random motions of atoms filtered through the sophisticated structures of our evolved machinery. People are essentially giant assemblies of interacting nanoscale machines.

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
In Die Hard style, Silas Cade takes his atypical brand of "auditing" from Wall Street to Main Street Fans of Lee Child's Jack Reacher and Vince Flynn's Mitch Rapp will want to add Silas Cade to their lineup. Cade, the tough-guy auditor antihero introduced in Clawback, employs a brand of financial reform that comes with plenty of firepower. Needing a respite from Wall Street, Cade jumps at a job opportunity in western Pennsylvania—but finds that Main Street is just as dirty. The job seems easy enough—check out a Pittsburgh manufacturer and file a report—but Cade quickly discovers corruption at every level. His revelations catch the attentions of hair-trigger Russian mobsters and a blonde assassin named Harmony. Cade’s estranged brother is dragged into the fray as the tension builds to bullet-riddled showdowns across defunct steel mills, forests, and Appalachian fracking fields. Cooper again delivers a timely plot involving Wall Street greed, financial corruption, and the plight of blue-collar workers.

Book Description
This book enters as a corrective to the tendency to trivialize and (mis)appropriate African American language practices. The word ratchet has entered into a wider (whiter) American discourse the same way that many words in African American English have—through hip-hop and social media. Generally, ratchet refers to behaviors and cultural expressions of Black people that sit outside of normative, middle-class respectable codes of conduct. Ratchet can function both as a tool for critiquing bad Black behavior, and as a tool for resisting the notion that there are such things as “good” and “bad” behavior in the first place. This book takes seriously the way ratchet operates in the everyday lives of middle-class and upwardly mobile Black Queer women in Washington, DC who, because of their sexuality, are situated outside of the norms of (Black) respectability. The book introduces the concept of “ratchet/boojie cultural politics” which draws from a rich body of Black intellectual traditions which interrogate the debates concerning what is and is not “acceptable” Black (middle-class) behavior. Placing issues of non-normative sexuality at the center of the conversation about notions of propriety within normative modes of Black middle-class behavior, this book discusses what it means for Black Queer women’s bodies to be present within ratchet/boojie cultural projects, asking what Black Queer women’s increasing visibility does for the everyday experiences of Black queer people more broadly.

Book Description
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.

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
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.
