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.

Water dominates the surface of Earth and is vital to life on our planet. It is a remarkable liquid which shows anomalous behaviour. In this Very Short Introduction John Finney introduces the science of water, and explores how the structure of water molecules gives rise to its physical and chemical properties. Considering water in all three of its states as ice and steam as well as liquid, Finney explains the great importance of an understanding of its structure and behaviour to a range of fields including chemistry, astrophysics, and earth and environmental sciences. Finney describes the role of water in biology, and ends with a discussion of the outstanding controversies concerning water, and some of the 'magical' properties which have been claimed for it. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

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.

#1 NEW YORK TIMES BESTSELLER "Should be read by every leader in America...a book to inspire your children and grandchildren to become everything that they can." --Wall Street Journal "Powerful." --USA Today "Full of captivating personal anecdotes from inside the national security vault." --Washington Post "Superb, smart, and succinct." --Forbes BASED ON THE INCREDIBLE GRADUATION SPEECH WITH OVER 10 MILLION VIEWS ON YOUTUBE If you want to change the world, start off by making your bed. On May 17, 2014, Admiral William H. McRaven addressed the graduating class of the University of Texas at Austin on their Commencement day. Taking inspiration from the university's slogan, "What starts here changes the world," he shared the ten principles he learned during Navy Seal training that helped him overcome challenges not only in his training and long Naval career, but also throughout his life; and he explained how anyone can use these basic lessons to change themselves-and the world-for the better. Admiral McRaven's original speech went viral with over 10 million views. Building on the core tenets laid out in his speech, McRaven now recounts tales from his own life and from those of people he encountered during his military service who dealt with hardship and made tough decisions with determination, compassion, honor, and courage. Told with great humility and optimism, this timeless book provides simple wisdom, practical advice, and words of encouragement that will inspire readers to achieve more, even in life's darkest moments.
