  How encounters with strongly electric fish informed our grasp of electricity. 
   
  Spark from the Deep tells the story of how human beings came to understand and use electricity by studying the evolved mechanisms of strongly electric fish. These animals can shock potential prey or would-be predators with high-powered electrical discharges. 
   
  William J. Turkel asks completely fresh questions about the evolutionary, environmental, and historical aspects of people’s interest in electric fish. Stimulated by painful encounters with electric catfish, torpedos, and electric eels, people learned to harness the power of electric shock for medical therapies and eventually developed technologies to store, transmit, and control electricity. Now we look to these fish as an inspiration for engineering new sensors, computer interfaces, autonomous undersea robots, and energy-efficient batteries. 
   
  Praise for Spark from the Deep 
   
  “This beautifully written and exhaustively researched book traces the links between experiments on strongly electric fish and scientific understanding of electricity . . . Turkel’s book is a joy to read; it will entertain and educate scientists, historians, and anyone with an interest in the natural world.” —Choice 
   
  “Turkel’s book convincingly reminds us that all the laptops and gadgets we surround ourselves with are remixes; altered versions of strongly electric fish. For that strange and insightful observation, this book ought to be widely read and enjoyed.” —Chris Conway, Endeavour 
   
  “[I]t is refreshing to explore a book which takes seriously ancient encounters with manifestations of natural electricity as precursors to more recent innovations.” —James F. Stark, The British Journal for the History of Science

  It has been said many times, that " the world is changing ", but often, we don’t understand the impact of this statement.  Global warming is not only a problem for the rich, the business community, or scientists, It is about all of us. It affects us all, and we need to understand how it works so that we can make necessary changes to adapt to a changed world.  The world is changing, and we need to stop and look at things around us. Here are some of the biggest indicators of global warming: The Amazon rainforest wildfires, Polar ice caps melting, Increased natural disasters.All of these and more are happening because of global warming and climate change that are happening across the globe.  The thing is, global warming isn't a new trend or a new phenomenon. Scientists have been warning us about this issue since the 1890s, yet we still haven't progressed as much as we should have.We must act now to make this world a better place for the future generation.Are you wondering how to do that?You can start here with this book.

  The Lean Farm - How to Minimize...

  A practical, systems-based approach for a more sustainable farming operation 
  To many people today, using the words “factory” and “farm” in the same sentence is nothing short of sacrilege. In many cases, though, the same sound business practices apply whether you are producing cars or carrots. Author Ben Hartman and other young farmers are increasingly finding that incorporating the best new ideas from business into their farming can drastically cut their wastes and increase their profits, making their farms more environmentally and economically sustainable. By explaining the lean system for identifying and eliminating waste and introducing efficiency in every aspect of the farm operation, The Lean Farm makes the case that small-scale farming can be an attractive career option for young people who are interested in growing food for their community. Working smarter, not harder, also prevents the kind of burnout that start-up farmers often encounter in the face of long, hard, backbreaking labor.  Lean principles grew out of the Japanese automotive industry, but they are now being followed on progressive farms around the world. Using examples from his own family’s one-acre community-supported farm in Indiana, Hartman clearly instructs other small farmers in how to incorporate lean practices in each step of their production chain, from starting a farm and harvesting crops to training employees and selling goods. While the intended audience for this book is small-scale farmers who are part of the growing local food movement, Hartman’s prescriptions for high-value, low-cost production apply to farms and businesses of almost any size or scale that hope to harness the power of lean in their production processes.

  The founder of Wild Food Adventures presents the definitive, fully illustrated guide to foraging and preparing wild edible greens.Beyond the confines of our well-tended vegetable gardens, there is a wide variety of fresh foods growing in our yards, neighborhoods, or local woods. All that’s needed to take advantage of this wild bounty is a little knowledge and a sense of adventure. In Edible Wild Plants, wild foods expert John Kallas covers easy-to-identify plants commonly found across North America. The extensive information on each plant includes a full pictorial guide, recipes, and more.This volume covers four types of wild greens:Foundation Greens: wild spinach, chickweed, mallow, and purslaneTart Greens: curlydock, sheep sorrel, and wood sorrelPungent Greens: wild mustard, wintercress, garlic mustard, and shepherd’s purseBitter Greens: dandelion, cat’s ear, sow thistle, and nipplewort

  The connected world offers the potential for radical new business insights gleaned from previously unimaginable volumes of data. But business has got bogged down in the process of collecting and storing that data; money has been wasted on data lakes in which many IT departments have drowned without being able to deliver useful insights to business leaders. Big data has new and exciting answers to offer, but business leaders must first decide what questions it would like to see answered. Data may be the new oil, but to date we have only built oil depots. This book analyses the new, Fourth Wave of business transformation, which will build the refineries that turn data into useful products. Business has started from ‘data up’ and needs to start again from ‘value down’, going back to the drivers of real business value and deciding what insights would help realize that value. Only then can we begin to interrogate data with purpose.

  The Shape of a Life - One...

  A Fields medalist recounts his lifelong effort to uncover the geometric shape—the Calabi-Yau manifold—that may store the hidden dimensions of our universe. 
   
  Harvard geometer Shing-Tung Yau has provided a mathematical foundation for string theory, offered new insights into black holes, and mathematically demonstrated the stability of our universe. In this autobiography, Yau reflects on his improbable journey to becoming one of the world’s most distinguished mathematicians. Beginning with an impoverished childhood in China and Hong Kong, Yau takes readers through his doctoral studies at Berkeley during the height of the Vietnam War protests, his Fields Medal–winning proof of the Calabi conjecture, his return to China, and his pioneering work in geometric analysis. This new branch of geometry, which Yau built up with his friends and colleagues, has paved the way for solutions to several important and previously intransigent problems. 
   
  With complicated ideas explained for a broad audience, this book offers not only insights into the life of an eminent mathematician, but also an accessible way to understand advanced and highly abstract concepts in mathematics and theoretical physics. 
   
  “The remarkable story of one of the world’s most accomplished mathematicians . . . Yau’s personal journey—from escaping China as a youngster, leading a gang outside Hong Kong, becoming captivated by mathematics, to making breakthroughs that thrust him on the world stage—inspires us all with humankind’s irrepressible spirit of discovery.” —Brian Greene, New York Times–bestselling author of The Elegant Universe 
   
  “An unexpectedly intimate look into a highly accomplished man, his colleagues and friends, the development of a new field of geometric analysis, and a glimpse into a truly uncommon mind.” —The Boston Globe 
   
  “Engaging, eminently readable. . . . For those with a taste for elegant and largely jargon-free explanations of mathematics, The Shape of a Life promises hours of rewarding reading.” —American Scientist
