The Big Ratchet

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.

Move over Diary of a Wimpy Kid—there's a new journal in town and it belongs to Ratchet. "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.

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 saga of love, loyalty, and crime continues in the next explosive book in the Cartel series from the minds of New York Times bestselling authors Ashley & JaQuavis. After the tragic and bloody end to The Cartel’s reign, Carter is forced into isolation to evade the law. With his wife, Miamor, facing federal charges and his dear brother, six feet under, Carter has never been more alone. His empire is at his feet and he has no idea how to rebuild his kingdom. The only thing that is certain is that he has to stay out the way and off the radar of the Feds until he can figure out how to get his lady out of prison. Miamor’s freedom is guaranteed—provided Carter help create and distribute a drug that will take the streets by storm. Rubbing elbows with the most notorious, ruthless leaders of the underworld will get him what he wants. But can he win at their game of murder and money?

The pace of energy use, greenhouse gas emissions, and population growth has thrust the planet into a new age—the Anthropocene. Humans have altered the planet’s biogeochemical systems without consciously managing them. The Great Acceleration explains the causes, consequences, and uncertainties of this massive uncontrolled experiment.

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.
