    In the paper, Wigner observed that the mathematical structure of a physical theory often points the way to further advances in that theory and even to empirical predictions.

    Includes such gems as:? There are 42 eyes in a deck of cards, and 42 dots on a pair of dice ? In order to fill in a map so that neighboring regions never get the same color, one never needs more than four colors ? Hells Angels use the number 81 in their insignia because the initials H and A are the eighth and first numbers in the alphabet respectively

    The presentation develops physical insight by stressing the microscopic content of the theory.

    It discusses how to plan your stargazing and what you can see with your eyes, as well as how to choose binoculars and telescopes and what you can see using them. The book also offers seasonal star charts and constellation charts and gives readers specific objects to look for in the sky. This guide from Royal Observatory Greenwich provides all you need to know to get started in stargazing and discover the universe.

    This text provides a thorough exposition of the principles of thermodynamics and details their application to chemical processes. The new edition has been updated to reflect the growth in such areas as materials and electrochemicals.

    Proven with mathematics this book describes genuine ancient knowledge that conflicts with modern science but upholds the Biblical story of Genesis.

    A tale of exploration, conquest, money, politics, and medicine, Panama Fever charts the challenges that marked the long, labyrinthine road to the building of the canal. Drawing on a wealth of new materials and sources, Matthew Parker brings to life the men who recognized the impact a canal would have on global politics and economics, and adds new depth to the familiar story of Teddy Roosevelt's remarkable triumph in making the waterway a reality.As thousands of workers succumbed to dysentery, yellow fever, and malaria, scientists raced to stop the deadly epidemics so that work could continue. The treatments they developed changed the course of medical history. The opening of the Panama Canal in 1914 spelled the end of the Victorian Age and the beginning of the "American Century." Panama Fever brilliantly captures the innovative thinking and backbreaking labor, as well as the commercial and political interests, that helped make America a global power.

    Using playing cards, a newspaper, the back of an envelope, a Sudoku, some pennies and of course a pair of socks, Rob Eastaway shows how maths can demonstrate its secret beauties in even the most mundane of everyday objects. Among the many fascinating curiosities in these pages, you will discover the strange link between limericks and rabbits, an apparently 'fair' coin game where the odds are massively in your favour, why tourist boards can't agree on where the centre of Britain is, and how simple paper folding can lead to a Jurassic Park monster. With plenty of ideas you'll want to test out for yourself, this engaging and refreshing look at mathematics is for everyone.

    Courses tailored to fit individual pupils. Textbooks that talk back. This is tomorrow’s education landscape, thanks to the power of big data. These advances go beyond the much-discussed rise of online courses. As the New York Times-bestselling authors of Big Data explain, the truly fascinating changes are actually occurring in how we measure students’ progress and how we can use that data to improve education for everyone, in real time, both on- and offline. Learning with Big Data offers an eye-opening, insight-packed tour through these new trends, for educators, administrators, and readers interested in the latest developments in business and technology.

    

    Genealogists and adoptees are using them and other DNA tests to identify ancestors, confirm relationships, and measure their ethnicity. Unfortunately, there are many similar sounding tests and some of them have different testing levels. So it’s easy to order the wrong test or pay too much. This Guide to DNA Testing provides an easy-to-understand introduction to the different test types, their strengths and limitations. Author and adoptee, Richard Hill, shared his personal success story in his book, "Finding Family: My Search for Roots and the Secrets in My DNA.” Now he boils down the basics of genetic genealogy into this concise summary. Learn which tests are right for you. Hyperlinks to specific tests and resources are included.

    Author Jigar Shah, internationally recognized for revolutionizing the now multi-billion-dollar solar energy industry, outlines how entrepreneurs and investors can unlock the massive potential that climate change represents. Shah argues that, while new technical innovation is valuable, deployment of existing technologies are the key to reaching our near-term climate targets. Rather than waiting for yet to be developed technology, business model innovation is the key to attract mainstream capital and unlock transformational change. Shah makes a compelling case for reaching our 2020 climate change goals through 100,000 companies worldwide, each generating $100 million in sales. Unlocking our next economy will be driven by thousands of companies deploying existing clean and resource-efficient technologies in electricity-supply (like solar), transportation, building materials, industry, forestry, waste, and agriculture. Shah is not alone; according to the International Energy Agency, and others, $10 trillion can be invested profitably—today—in the world’s existing technologies, making Shah’s plan of 100,000 companies each generating $100 million in sales a reality in catalyzing a new economy in the process. Creating Climate Wealth is also the personal story of Shah’s journey through the solar industry and the founding of SunEdison, the world’s largest solar energy company. Through business model innovations, SunEdison helped trigger the multi-billion dollar solar energy services industry. Shah’s revolutionary approach has been emulated throughout the solar industry. But perhaps more important, it is also being adapted for other industrial sectors like agriculture and transportation – unlocking incredible new revenue streams, creating hundreds of thousands of jobs, and positively transforming the planet on a global level. This implementation of business-based solutions to solve complex social problems represents a new economic movement; driven by “Impact Investments.” Impact Investments are changing the world for the better, promoting development and economic growth, and encouraging local entrepreneurship. Unlocking these opportunities represent the largest wealth creation opportunity of our generation. Whether you are interested in climate change, poverty alleviation, or just promoting projects that make financial sense, this book is for you. Jigar Shah provides a proven roadmap to understanding the Impact Economy, and creating the lasting changes that will improve our world for future generations.
