Guesstimation is a book that unlocks the power of approximation--it's popular mathematics rounded to the nearest power of ten! The ability to estimate is an important skill in daily life. More and more leading businesses today use estimation questions in interviews to test applicants' abilities to think on their feet. Guesstimation enables anyone with basic math and science skills to estimate virtually anything--quickly--using plausible assumptions and elementary arithmetic. Lawrence Weinstein and John Adam present an eclectic array of estimation problems that range from devilishly simple to quite sophisticated and from serious real-world concerns to downright silly ones. How long would it take a running faucet to fill the inverted dome of the Capitol? What is the total length of all the pickles consumed in the US in one year? What are the relative merits of internal-combustion and electric cars, of coal and nuclear energy? The problems are marvelously diverse, yet the skills to solve them are the same. The authors show how easy it is to derive useful ballpark estimates by breaking complex problems into simpler, more manageable ones--and how there can be many paths to the right answer. The book is written in a question-and-answer format with lots of hints along the way. It includes a handy appendix summarizing the few formulas and basic science concepts needed, and its small size and French-fold design make it conveniently portable. Illustrated with humorous pen-and-ink sketches, Guesstimation will delight popular-math enthusiasts and is ideal for the classroom.
Violent political conflict and climate change threaten us all. Governments and international bodies have failed to respond in any meaningful way. They continue to fund activities and institutions that are only tenuously linked with social and environmental goals. Social Policy Bonds are a new financial instrument that could revolutionize policymaking. By issuing them, governments and the private sector could inextricably tie rewards to outcomes, and inject market incentives into the achievement of such universally desired goals as world peace and climate stability.Ronnie Horesh's Social Policy Bond concept has been praised by distinguished economists. He has spoken about it in such forum as the Organization for Economic Co-operation and Development (OECD), Cambridge University and think tanks in the United Kingdom, Australia and New Zealand.
The "World" in Robert Lee Brewer's Solving the World's Problems is a slippery world ... where chaos always hovers near, where we are (and should be) "splashing around in dark puddles." And one feels a bit dizzy reading these poems because (while always clear, always full of meaning) they come at reality slantwise so that nothing is quite the same and the reader comes away with a new way of looking at the ordinary objects and events of life. The poems are brim-full of surprises and delights, twists in the language, double-meanings of words, leaps of thought and imagination, interesting line-breaks. There are love and relationship poems, dream poems, poems of life in the modern world. And always the sense (as he writes) of "pulling the world closer to me/leaves falling to the ground/ birds flying south." I read these once, twice with great enjoyment. I will go back to them often. -Patricia Fargnoli, former Poet Laureate of New Hampshire and author of Then, Something
'An original and vital contribution to understanding politics.' - Matt Ridley, author of The Rational OptimistHow to solve the world's trickiest political problems? In Reframe,Eric Knight explains how a change of focus can reveal a solution that was lying just outside your frame of vision. From terrorism to global warming, from border security to high finance, he brings a new perspective that is both exhilarating and useful. Why can't we eliminate terrorism by killing terrorists? Why can't we learn anything about climate change by talking about the weather? Why can't we resolve immigration tensions by building higher fences? And what do fishermen in Turkey have to teach us about international relations? This is an optimistic, lucid and original book by a brilliant young Australian thinker.
This is the eBook version of the printed book. This Element is an excerpt from Out of Water: From Abundance to Scarcity and How to Solve the World’s Water Problems (9780131367265) by Colin Chartres and Samyuktha Varma. Available in print and digital formats. The “Blue Revolution”: how to overcome the emerging global water crisis that will lead to food crises, unrest, and uncontrolled mass migration Lack of water for growing food will be one of the 21st century’s most critical issues. If we don’t change how we manage water, the future will consist of increasingly frequent food crises, social and political unrest, and potential mass migrations out of areas most severely affected. We need to consider a “Blue Revolution.”
This book attempts to address the major world problems of today with suggested solutions. Discussed are the many problems our society deals with on a daily basis, such as water shortages, natural disasters, public violence, financial institutions, and the family unit as a whole. Through these ideas, many possibilities are brought forth for the reader to ponder.
Dealing with Human Race, Human Rights, Philosophy, Scientific, Religious, and World Economic Issues

My sixth book, The World’s Problems and Solutions, discusses many issues concerning the world, and from these debates, analysis, and development, many people in the world will find the solution to most of the problems in their countries. There is not only one problem, such as the world financial crisis – there are many crises that affect the world. From my research, I believe that there is also war on religion that affects the world, and the governments have a duty to serve the population rather the population serving the governments. I discover there is even a problem about the human race as a whole: scientist experiments do not provide exact information because they are still discovering more information about the human race. Many people have their own philosophical methods to find the solutions in their continent and also in their countries. Therefore my research and analysis seeks to expose the solution to many problems in the world. The politicians, governments, religions, and others world institutions will find this book very interesting for humanity’s development.
The world has many pressing problems. Thanks to the efforts of governments, NGOs, and individual activists there is no shortage of ideas for resolving them. However, even if all governments were willing to spend more money on solving the problems, we cannot do it all at once. We have to prioritize; and in order to do this we need a better sense of the costs and benefits of each 'solution'. This book offers a rigorous overview of twenty-three of the world's biggest problems relating to the environment, governance, economics, and health and population. Leading economists provide a short survey of the analysis and sketch out policy solutions for which they provide cost-benefit ratios. A unique feature is the provision of freely downloadable software which allows readers to make their own cost-benefit calculations for spending money to make the world a better place.
Strategies for long-term social impact This important new book illustrates how to create the social breakthroughs needed to solve urgent global threats such as poverty, disease, and hunger. It then turns to three alternative, but complementary, paths to social breakthrough: social protecting, social exploring, and social advocacy, providing a detailed map of the journey from initial commitment to a world of justice and opportunity Examines the current condition of the social impact infrastructure Offers strategies for how to remedy the steady weakening of our social-impact infrastructure Provides tactics to build strong social organizations and networks Illustrates dynamic methods to respond to constant economic and social change Author Paul Light believes we should be less concerned about the tools of agitation (social entrepreneurship, social protecting, social exploring, and social advocacy) and more concerned about the disruption and replacement of the status quo. Timely in its urgency, this book describes the revolutionary social impact cycle, which provides a new approach for framing the debate about urgent threats.
