This is a story about sand and how science and silicon changed our lives. Over the last century science taught us to take this common material and make the products on which we depend - computer chips, solar cells and optical fibers. This book relates the underlying scientific discoveries to the products made from sand.

This is a story about sand and how science and silicon changed our lives. Over the last century, science taught us how to take this most common material and create the products on which we depend. It allows us to determine the atomic structure of materials and to grow novel, new materials atomic layer by atomic layer. The principles of thermodynamics are used to transform sand into ultra pure silicon. Quantum mechanics gave birth to the electronic age and the computer chip in which dopants are precisely placed in ultra pure silicon. The absorption and emission and reflection of quanta of light, photons, underlies solar cells, light emitting diodes, radiation detectors and optical fibers. This book follows the history of these scientific discoveries and relates them to the products made from sand.

Young children are intuitive, emergent scientists - they observe, raise hypotheses, experiment and notice patterns. Most of our everyday actions at home and in other settings, inside and outside, have a scientific basis and it is through these early experiences that children formulate their ideas about the world in which we live. This accessible book introduces the simplest form of the principles and the big ideas of science and provides a starting point for encouraging children to have an interest and experiential understanding of basic science and engineering. It shows you how you can support young children in exploring everyday phenomena and develop their scientific language skills through readily available resources and hands-on experiences. Each chapter focuses on a different aspect of science and includes: a summary of the ‘big ideas’ to refresh your own scientific knowledge; numerous activities that encourage young children to observe, question and carry out their own investigations; a usefil list of everyday resources and relevant vocabulary. Providing a wealth of exciting, meaningful ways to promote scientific experiences and learning, this highly practical book will help you to build on children’s natural curiosity about the world and develop their understanding through your everyday provision in early years settings and at home.

Thirty years after women became 50 percent of the college graduates in the United States, men still hold the vast majority of leadership positions in government and industry. This means that women’s voices are still not heard equally in the decisions that most affect our lives. In Lean In, Sheryl Sandberg examines why women’s progress in achieving leadership roles has stalled, explains the root causes, and offers compelling, commonsense solutions that can empower women to achieve their full potential. Sandberg is the chief operating officer of Facebook and is ranked on Fortune’s list of the 50 Most Powerful Women in Business and as one of Time’s 100 Most Influential People in the World. In 2010, she gave an electrifying TEDTalk in which she described how women unintentionally hold themselves back in their careers. Her talk, which became a phenomenon and has been viewed more than two million times, encouraged women to “sit at the table,” seek challenges, take risks, and pursue their goals with gusto. In Lean In, Sandberg digs deeper into these issues, combining personal anecdotes, hard data, and compelling research to cut through the layers of ambiguity and bias surrounding the lives and choices of working women. She recounts her own decisions, mistakes, and daily struggles to make the right choices for herself, her career, and her family. She provides practical advice on negotiation techniques, mentorship, and building a satisfying career, urging women to set boundaries and to abandon the myth of “having it all.” She describes specific steps women can take to combine professional achievement with personal fulfillment and demonstrates how men can benefit by supporting women in the workplace and at home. Written with both humor and wisdom, Sandberg’s book is an inspiring call to action and a blueprint for individual growth. Lean In is destined to change the conversation from what women can’t do to what they can. This eBook edition includes a Reading Group Guide.

The richly told narrative of the Silicon Valley generation that launched five major high-tech industries in seven years, laying the foundation for today’s technology-driven world. At a time when the five most valuable companies on the planet are high-tech firms and nearly half of Americans say they cannot live without their cell phones, Troublemakers reveals the untold story of how we got here. This is the gripping tale of seven exceptional men and women, pioneers of Silicon Valley in the 1970s and early 1980s. Together, they worked across generations, industries, and companies to bring technology from Pentagon offices and university laboratories to the rest of us. In doing so, they changed the world. In Troublemakers, historian Leslie Berlin introduces the people and stories behind the birth of the Internet and the microprocessor, as well as Apple, Atari, Genentech, Xerox PARC, ROLM, ASK, and the iconic venture capital firms Sequoia Capital and Kleiner Perkins Caufield & Byers. In the space of only seven years and thirty-five miles, five major industries—personal computing, video games, biotechnology, modern venture capital, and advanced semiconductor logic—were born. During these same years, the first ARPANET transmission came into a Stanford lab, the university began licensing faculty innovations to businesses, and the Silicon Valley tech community began mobilizing to develop the lobbying clout and influence that have become critical components of modern American politics. In other words, these were the years when one of the most powerful pillars of our modern innovation and political systems was first erected. Featured among well-known Silicon Valley innovators like Steve Jobs, Regis McKenna, Larry Ellison, and Don Valentine are Mike Markkula, the underappreciated chairman of Apple who owned one-third of the company; Bob Taylor, who kick-started the Arpanet and masterminded the personal computer; software entrepreneur Sandra Kurtzig, the first woman to take a technology company public; Bob Swanson, the cofounder of Genentech; Al Alcorn, the Atari engineer behind the first wildly successful video game; Fawn Alvarez, who rose from an assembler on a factory line to the executive suite; and Niels Reimers, the Stanford administrator who changed how university innovations reach the public. Together, these troublemakers rewrote the rules and invented the future.

New York Times Bestseller • New York Times Notable Book 2014 • Winner of the Royal Society Winton Prize for Science Books “A thrilling account of the modern material world.” —Wall Street Journal "Miodownik, a materials scientist, explains the history and science behind things such as paper, glass, chocolate, and concrete with an infectious enthusiasm." —Scientific American Why is glass see-through? What makes elastic stretchy? Why does any material look and behave the way it does? These are the sorts of questions that renowned materials scientist Mark Miodownik constantly asks himself. Miodownik studies objects as ordinary as an envelope and as unexpected as concrete cloth, uncovering the fascinating secrets that hold together our physical world. In Stuff Matters, Miodownik explores the materials he encounters in a typical morning, from the steel in his razor to the foam in his sneakers. Full of enthralling tales of the miracles of engineering that permeate our lives, Stuff Matters will make you see stuff in a whole new way. "Stuff Matters is about hidden wonders, the astonishing properties of materials we think boring, banal, and unworthy of attention...It's possible this science and these stories have been told elsewhere, but like the best chocolatiers, Miodownik gets the blend right." —New York Times Book Review
