Smoking has gone from doctor recommended to deadly. We used to think the Earth was the center of the universe and that Pluto was a planet. For decades, we were convinced that the brontosaurus was a real dinosaur. In short, what we know about the world is constantly changing.   But it turns out there’s an order to the state of knowledge, an explanation for how we know what we know. Samuel Arbesman is an expert in the field of scientometrics—literally the science of science. Knowl­edge in most fields evolves systematically and predict­ably, and this evolution unfolds in a fascinating way that can have a powerful impact on our lives.   Doctors with a rough idea of when their knowl­edge is likely to expire can be better equipped to keep up with the latest research. Companies and govern­ments that understand how long new discoveries take to develop can improve decisions about allocating resources. And by tracing how and when language changes, each of us can better bridge gen­erational gaps in slang and dialect.   Just as we know that a chunk of uranium can break down in a measurable amount of time—a radioactive half-life—so too any given field’s change in knowledge can be measured concretely. We can know when facts in aggregate are obsolete, the rate at which new facts are created, and even how facts spread.   Arbesman takes us through a wide variety of fields, including those that change quickly, over the course of a few years, or over the span of centuries. He shows that much of what we know consists of “mesofacts”—facts that change at a middle timescale, often over a single human lifetime. Throughout, he of­fers intriguing examples about the face of knowledge: what English majors can learn from a statistical analysis of The Canterbury Tales, why it’s so hard to measure a mountain, and why so many parents still tell kids to eat their spinach because it’s rich in iron.   The Half-life of Facts is a riveting journey into the counterintuitive fabric of knowledge. It can help us find new ways to measure the world while accepting the limits of how much we can know with certainty.

    As energy costs continue to rise, the almost-off-the-grid house proves its worth. Prefabulous + Almost Off the Grid profiles more than 30 of the most energy-efficient homes in the United States, and this hardworking guide reveals how homeowners can achieve similar results with floor plans, the latest, most efficient technologies, and multiple images of the exterior and interior of each home. Praise for Prefabulous + Almost Off the Grid: Recipient of the 2013 Robert Bruss Gold Book Award from the National Association of Real Estate Editors (NAREE) “You can build a high quality, environmentally friendly and efficient home at a reasonable price with a look and feel of a traditional home. Advancements like those used in our house and the other houses in this book will transform the homebuilding industry.” —Christine Todd Whitman, former governor of New Jersey and administrator of the Environmental Protection Agency “The time has come to throw out the old stereotypes and to embrace prefab building techniques as the way of the future—and the best approach for today. For anyone wanting to create a house that’s sustainable in every sense of the word, this book is an excellent place to start.” —Sarah Susanka, architect and author of The Not So Big House series “I'm passionate about prefab because I know that it can spark an incredibly positive change in the building industry and dramatically reduce costs and construction duration. Prefabulous + Almost Off the Grid is an enlightening guide on using prefab to create your own affordable, energy-efficient home.” —Bruce Ratner, chairman and chief executive of the Forest City Ratner Companies “Sheri Koones highlights the many ways of using prefabrication to create almost-off-the-grid homes that are not only environmentally friendly but often operate at nearly zero annual energy cost. . . . This is an easy-on-the-eyes guide that includes floor plans and multiple images of the exterior and interior of each home. It is not a manual for green construction, but a general overview of aspects of prefab and green construction. And it does that well.” —Natural Life magazine “If you’re ready to do something about your energy dependence, or if you enjoy stories of people who’ve bucked the trends, you owe it to yourself to give Prefabulous + Almost Off the Grid a look. Beautifully illustrated, it ends with a great resources list for the homes showcased.” —Examiner.com “Indispensable guide to creating the ideal, almost-off-the-grid home. . . . This text is both timely and tempting to anyone interested in inhabiting a more comfortable and cost-efficient abode.” —Bask “This attractive coffee-table-style book, the third in Koones’s Prefabulous series, features 32 prefabricated houses that, to a greater or lesser extent, boast environmentally friendly, efficient, and renewable-energy elements.” —Publishers Weekly

    It is important for every person to save for one’s retirement as one can expect to live for twenty years after one retires as life expectancy of an Indian is going up steadily due to lower infant mortality and better medical care. There is a complete absence of social security safety net for most Indians today, even for those working in Government sector, there is no inflation adjusted pension available anymore. I have tried to simplify the advantages and disadvantages involved in investing your savings in various asset classes. I have deliberately left out two of the most popular forms of investment among middle class Indians 1) Life insurance 2) Real estate Let us consider life insurance first most of us confuse insurance as an instrument of savings, it is not. We have this wrong view because of the tax breaks given to income tax assesses by the Central Government. Insurance is a product that mitigates risk and is sold by the rich to the middle class and is always skewed in the favour of the insurer rather than the insured. A substantial portion of the total money invested by you goes towards paying agent’s commission and premium for insuring you for the risk of mortality. The balance left out is invested in government securities and other securities. Hence the amount of money invested out of the total premium paid is less than half paid by the insurer. The return on money invested by the policy holder is less than half of the money he would have earned either in bonds or fixed deposits. A person who needs insurance is a person whose family will need support in the event of his untimely death. Alternately insurance is required for a person who has debt in form of mortgage and does not want to burden his family in the event of his passing. The product which covers these risks is called term insurance. One should not buy insurance to avoid taxes as there is better tax saving tools available. Real estate is also considered as a good investment by several retail investors but nothing can be further from the truth. Nobody makes money by buying plots in the middle of nowhere. The easy availability of mortgages from the nineties and the tax breaks given by the Central Government on housing loans has created an unparalleled boom in the residential market. There is now a painful correction process under way in that sector. The price of land is reflexively connected to availability of money. The lower the cost of money, greater the returns in real estate. Buying plots in the middle of nowhere is similar to buying lottery tickets as investment. Land cannot be liquidated immediately into cash at a short notice to meet urgent requirements. Cost of maintenance and protection of real estate from illegal occupation is prohibitive and time consuming. Verification of title deeds to the property is a complex process and needs sound legal advice. You should have a house to live and another to collect rent as rent is equivalent of inflation adjusted pension. The return on investment generated in the three different asset classes over 25 years would be in the following order 1) Equities 2) Gold and finally 3) Debt instruments. I enjoyed writing this book as a companion volume to my first book. It is my fond hope that you enjoy reading this book.

    Good to Great Summarized for Busy People

    The authors write: "Oil is the problem. Cars are the solution." We are living in the midst of a Great Awakening in which environmentalists, entrepreneurs, and political leaders are forming new alliances to end our addiction to oil and create new technologies. The days of Big Oil and Big Auto are numbered, according to the authors, who show how we are in the midst of a major transformation from carbon-based energy sources to new fuels and technologies.ZOOM traces the history of the linked industries of oil and automobiles, and how the two have shaped domestic capitalism and the international landscape, creating both progress and peril. They explain how Toyota vanquished American competitors to become the world's largest automobile manufacturer and, more importantly, a leader in hybrid cars using electric power. They take us into the boardrooms of oil executives and show how some are boldly exploring new energy sources while others deny the dangers posed by oil and risk extinction. With wide-ranging analysis and a keen view of the key players in the intersecting worlds of energy and automobiles, authors Iain Carson and Vijay Vaitheeswaran tell the story of what may be the most important challenge facing the industrial world: How to make the transition from the Age of Petroleum to a cleaner and better future.

    interstate system changed the face of our country. The Big Roads charts the creation of these essential American highways. From the turn-of-the-century car racing entrepreneur who spurred the citizen-led “Good Roads” movement, to the handful of driven engineers who conceived of the interstates and how they would work—years before President Eisenhower knew the plans existed—to the protests that erupted across the nation when highways reached the cities and found people unwilling to be uprooted in the name of progress, Swift follows a winding, fascinating route through twentieth-century American life.  How did we get from dirt tracks to expressways, from main streets to off-ramps, from mud to concrete and steel, in less than a century? Through decades of politics, activism, and marvels of engineering, we recognize in our highways the wanderlust, grand scale, and conflicting notions of citizenship and progress that define America.

    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.

    Like Andrew Marr's HISTORY OF MODERN BRITAIN or Michael Palin's HIMALAYA, the book will have a coherence and life beyond the television series, mirroring its basic structure, but looking at some issues in greater depth, and telling additional stories to illustrate some of the ideas.This book is about the things that Britain produces in order to pay its way in the world, from physical goods that we can see and feel, to intangible services that are much harder to quantify. We don't have to be prejudiced in favour of certain types of value: we shouldn't assume finance is modern, and manufacturing out of date for example. What matters is what sells and for how much. From manufacturing to technology, design and the services industries, this book will provide a cutting edge analysis - via entertaining stories - about what we make and why it matters.

    Used in university courses and professional seminars all over the world, the text has proven its ability to open minds and sharpen thinking.Originally published in 1975 and reprinted more than twenty times over a quarter century -- and now available for the first time from Dorset House Publishing -- the text uses clear writing and basic algebraic principles to explore new approaches to projects, products, organizations, and virtually any kind of system.Scientists, engineers, organization leaders, managers, doctors, students, and thinkers of all disciplines can use this book to dispel the mental fog that clouds problem-solving. As author Gerald M. Weinberg writes in the new preface to the Silver Anniversary Edition, "I haven’t changed my conviction that most people don’t think nearly as well as they could had they been taught some principles of thinking.”Now an award-winning author of nearly forty books spanning the entire software development life cycle, Weinberg had already acquired extensive experience as a programmer, manager, university professor, and consultant when this book was originally published.With helpful illustrations, numerous end-of-chapter exercises, and an appendix on a mathematical notation used in problem-solving, An Introduction to General Systems Thinking may be your most powerful tool in working with problems, systems, and solutions.

    Dense urban living has been prescribed as a panacea for the environmental and resource crises of our time. But is it better or worse for our happiness? Are subways, sidewalks and condo towers an improvement on the car-dependence of sprawl?The award-winning journalist Charles Montgomery finds answers to such questions at the intersection between urban design and the emerging science of happiness, during an exhilarating journey through some of the world’s most dynamic cities. He meets the visionary mayor who introduced a “sexy” bus to ease status anxiety in Bogotá; the architect who brought the lessons of medieval Tuscan hill towns to modern-day New York City; the activist who turned Paris’s urban freeways into beaches; and an army of American suburbanites who have hacked the design of their own streets and neighborhoods.Rich with new insights from psychology, neuroscience and Montgomery’s own urban experiments, Happy City reveals how our cities can shape our thoughts as well as our behavior. The message is as surprising as it is hopeful: by retrofitting cities and our own lives for happiness, we can tackle the urgent challenges of our age. The happy city can save the world--and all of us can help build it.

    Digital technologies—with hardware, software, and networks at their core—will in the near future diagnose diseases more accurately than doctors can, apply enormous data sets to transform retailing, and accomplish many tasks once considered uniquely human.In The Second Machine Age MIT’s Erik Brynjolfsson and Andrew McAfee—two thinkers at the forefront of their field—reveal the forces driving the reinvention of our lives and our economy. As the full impact of digital technologies is felt, we will realize immense bounty in the form of dazzling personal technology, advanced infrastructure, and near-boundless access to the cultural items that enrich our lives.Amid this bounty will also be wrenching change. Professions of all kinds—from lawyers to truck drivers—will be forever upended. Companies will be forced to transform or die. Recent economic indicators reflect this shift: fewer people are working, and wages are falling even as productivity and profits soar.Drawing on years of research and up-to-the-minute trends, Brynjolfsson and McAfee identify the best strategies for survival and offer a new path to prosperity. These include revamping education so that it prepares people for the next economy instead of the last one, designing new collaborations that pair brute processing power with human ingenuity, and embracing policies that make sense in a radically transformed landscape.A fundamentally optimistic book, The Second Machine Age alters how we think about issues of technological, societal, and economic progress.

    Increasingly, the decisions that affect our lives--where we go to school, whether we can get a job or a loan, how much we pay for health insurance--are being made not by humans, but by machines. In theory, this should lead to greater fairness: Everyone is judged according to the same rules.But as mathematician and data scientist Cathy O'Neil reveals, the mathematical models being used today are unregulated and uncontestable, even when they're wrong. Most troubling, they reinforce discrimination--propping up the lucky, punishing the downtrodden, and undermining our democracy in the process.
