This important new work is a study of the everyday lives of the inhabitants of São Paulo in the nineteenth century. Full of vivid detail, the book concentrates on the lives of working women--black, white, Indian, mulatta, free, freed, and slaves, and their struggles to survive. Drawing on official statistics, and on the accounts of travelers and judicial records, the author paints a lively picture of the jobs, both legal and illegal, that were performed by women. Her research leads to some surprising discoveries, including the fact that many women were the main providers for their families and that their work was crucial to the running of several urban industries. This book, which is a unique record of women's lives across social and race strata in a multicultural society, should be of interest to students and researchers in women's studies, urban studies, historians, geographers, economists, sociologists, and anthropologists.

A fresh look at electricity and its powerful role in life on Earth When we think of electricity, we likely imagine the energy humming inside our home appliances or lighting up our electronic devices—or perhaps we envision the lightning-streaked clouds of a stormy sky. But electricity is more than an external source of power, heat, or illumination. Life at its essence is nothing if not electrical. The story of how we came to understand electricity’s essential role in all life is rooted in our observations of its influences on the body—influences governed by the body’s central nervous system. Spark explains the science of electricity from this fresh, biological perspective. Through vivid tales of scientists and individuals—from Benjamin Franklin to Elon Musk—Timothy Jorgensen shows how our views of electricity and the nervous system evolved in tandem, and how progress in one area enabled advancements in the other. He explains how these developments have allowed us to understand—and replicate—the ways electricity enables the body’s essential functions of sight, hearing, touch, and movement itself. Throughout, Jorgensen examines our fascination with electricity and how it can help or harm us. He explores a broad range of topics and events, including the Nobel Prize–winning discoveries of the electron and neuron, the history of experimentation involving electricity’s effects on the body, and recent breakthroughs in the use of electricity to treat disease. Filled with gripping adventures in scientific exploration, Spark offers an indispensable look at electricity, how it works, and how it animates our lives from within and without.

Demonstrates the importance of electricity and electrical devices in everyday life and explains where electricty comes from and how it gets from the power plant to the socket.

"This is a wonderful book. Frances Ashcroft has a rare gift for making difficult subjects accessible and fascinating." —Bill Bryson, author of The Body: A Guide for Occupants What happens during a heart attack? Can someone really die of fright? What is death, anyway? How does electroshock treatment affect the brain? What is consciousness? The answers to these questions lie in the electrical signals constantly traveling through our bodies, driving our thoughts, our movements, and even the beating of our hearts. The history of how scientists discovered the role of electricity in the human body is a colorful one, filled with extraordinary personalities, fierce debates, and brilliant experiments. Moreover, present-day research on electricity and ion channels has created one of the most exciting fields in science, shedding light on conditions ranging from diabetes and allergies to cystic fibrosis, migraines, and male infertility. With inimitable wit and a clear, fresh voice, award-winning researcher Frances Ashcroft weaves together compelling real-life stories with the latest scientific findings, giving us a spectacular account of the body electric.

Good Energy delivers a declaration that renewable energy can be beautiful, affordable, and easy to implement. Jared Green highlights thirty-five case studies from around the world, featuring a wide array of designs and building types that achieve good energy, good design, and excellent cost-efficiency. Single-family homes, townhouses, community spaces, schools, offices, and even power plants demonstrate that relying on solar, wind, and geothermal energy doesn't have to cost more. Each inspiring design harmonizes nature, technology, and democratic space and shows that renewable energy can be appealing and accessible to everyone. An interview with Mark Z. Jacobson, Stanford University professor of civil and environmental engineering and cofounder of the Solutions Project, discusses pathways to 100-percent renewable energy around the globe through good design.

Physics professor, bestselling author, and dynamic storyteller James Kakalios reveals the mind-bending science behind the seemingly basic things that keep our daily lives running, from our smart phones and digital “clouds” to x-ray machines and hybrid vehicles. Most of us are clueless when it comes to the physics that makes our modern world so convenient. What’s the simple science behind motion sensors, touch screens, and toasters? How do we glide through tolls using an E-Z Pass, or find our way to new places using GPS? In The Physics of Everyday Things, James Kakalios takes us on an amazing journey into the subatomic marvels that underlie so much of what we use and take for granted. Breaking down the world of things into a single day, Kakalios engages our curiosity about how our refrigerators keep food cool, how a plane manages to remain airborne, and how our wrist fitness monitors keep track of our steps. Each explanation is coupled with a story revealing the interplay of the astonishing invisible forces that surround us. Through this “narrative physics,” The Physics of Everyday Things demonstrates that—far from the abstractions conjured by terms like the Higgs Boson, black holes, and gravity waves—sophisticated science is also quite practical. With his signature clarity and inventiveness, Kakalios ignites our imaginations and enthralls us with the principles that make up our lives.
