New York Times Bestseller • Finalist for the Pulitzer Prize • An Oprah's Book Club Selection “Powerful . . . [Kingsolver] has with infinitely steady hands worked the prickly threads of religion, politics, race, sin and redemption into a thing of terrible beauty.” —Los Angeles Times Book Review The Poisonwood Bible, now celebrating its 25th anniversary, established Barbara Kingsolver as one of the most thoughtful and daring of modern writers. Taking its place alongside the classic works of postcolonial literature, it is a suspenseful epic of one family's tragic undoing and remarkable reconstruction over the course of three decades in Africa. The story is told by the wife and four daughters of Nathan Price, a fierce, evangelical Baptist who takes his family and mission to the Belgian Congo in 1959. They carry with them everything they believe they will need from home, but soon find that all of it—from garden seeds to Scripture—is calamitously transformed on African soil. The novel is set against one of the most dramatic political chronicles of the twentieth century: the Congo's fight for independence from Belgium, the murder of its first elected prime minister, the CIA coup to install his replacement, and the insidious progress of a world economic order that robs the fledgling African nation of its autonomy. Against this backdrop, Orleanna Price reconstructs the story of her evangelist husband's part in the Western assault on Africa, a tale indelibly darkened by her own losses and unanswerable questions about her own culpability. Also narrating the story, by turns, are her four daughters—the teenaged Rachel; adolescent twins Leah and Adah; and Ruth May, a prescient five-year-old. These sharply observant girls, who arrive in the Congo with racial preconceptions forged in 1950s Georgia, will be marked in surprisingly different ways by their father's intractable mission, and by Africa itself. Ultimately each must strike her own separate path to salvation. Their passionately intertwined stories become a compelling exploration of moral risk and personal responsibility.
Call it “Zen and the Art of Farming” or a “Little Green Book,” Masanobu Fukuoka’s manifesto about farming, eating, and the limits of human knowledge presents a radical challenge to the global systems we rely on for our food. At the same time, it is a spiritual memoir of a man whose innovative system of cultivating the earth reflects a deep faith in the wholeness and balance of the natural world. As Wendell Berry writes in his preface, the book “is valuable to us because it is at once practical and philosophical. It is an inspiring, necessary book about agriculture because it is not just about agriculture.” Trained as a scientist, Fukuoka rejected both modern agribusiness and centuries of agricultural practice, deciding instead that the best forms of cultivation mirror nature’s own laws. Over the next three decades he perfected his so-called “do-nothing” technique: commonsense, sustainable practices that all but eliminate the use of pesticides, fertilizer, tillage, and perhaps most significantly, wasteful effort. Whether you’re a guerrilla gardener or a kitchen gardener, dedicated to slow food or simply looking to live a healthier life, you will find something here—you may even be moved to start a revolution of your own.

In 1979 I took my first physics class in high school. I had always been pretty good in science and math, but physics was the perfect marriage of both. It explained everything in my mind. Sure, I had a basic understanding gravity, friction, drag, etc., but physics allowed you to precisely measure and calculate those fundamental properties.So, here we are over 30 years later. My son joined Cub Scouts as a Tiger Cub and we were exposed to one of the biggest annual physics experiments in the world.... The Pinewood Derby.Over the next four years, my son and daughter experienced a lot of success in the Pinewood Derby at both the pack and district level. In my son's final year of competition, he won the den, pack, and district races as well as a race that was held at the National Scouting Museum in Irving, Texas. I thought that was it for the Pinewood Derby, but I was wrong....At my kid's elementary school, fifth grade is the year that they all participate in the science fair. My wife and I were dreading the upcoming projects since we have twins. Then one day at work, a fellow engineer told me about how he and his son did a physics based science fair project. Bang! The light went on in my head and I thought, "Wow, why don't we do a project based on the physics of the Pinewood Derby." I pitched the idea to my kids and they were both all in.The problem with the science fair project was to figure out what we were trying to prove. We pretty much already knew how to build a winning car, so all we could really do is show how to make the car slower. So, that's what we did. We built a control/test car that applied all the best practices that we had learned along the road. Then we changed the mass, center of gravity, friction and drag to show how each of these attributes effected the performance of the car.My kids worked really hard on this project and by the end, really had a grasp of why the cars they had helped to build every year were so successful. It wasn't just luck, it was physics. The project came out great. I mean really great. They won their school's science fair and placed 2nd in the city wide district science fair. Personally, I would take those two victories over all the Pinewood Derby victories combined.As the project came to a conclusion, I came to a realization. There is a lot of info on the web about how to build a winning car. What you can't find is experimental data that quantifies the effect of not following the winning recipes. In other words, what is the sacrifice if you don't follow all the known speed secrets.This booklet attempts to quantify the sacrifices you can expect if you don't optimize the weight, center of gravity, drag and friction. The data my kids collected for their elementary science fair experiment will show you just how important each of these attributes are and what you can expect if you decide to cut corners.I also picked up a couple of speed secrets along the way. I will provide you with what I think are some really good tips on lubrication, polishing of axles and wheels, drag and friction reduction, weight placement and adjustment. In particular, the approach we used to polish and lubricate the axles and wheels is superior in my opinion.What I really hope is that this book helps you figure out quickly how to build a car that is very competitive without wasting a bunch of time on the web. Enjoy, and happy racing!
