We often overlook the historical link between mathematics and technological advances, says Stewart—but this connection is integral to any complete understanding of human history.Equations are modeled on the patterns we find in the world around us, says Stewart, and it is through equations that we are able to make sense of, and in turn influence, our world. Stewart locates the origins of each equation he presents—from Pythagoras's Theorem to Newton's Law of Gravity to Einstein's Theory of Relativity—within a particular historical moment, elucidating the development of mathematical and philosophical thought necessary for each equation's discovery. None of these equations emerged in a vacuum, Stewart shows; each drew, in some way, on past equations and the thinking of the day. In turn, all of these equations paved the way for major developments in mathematics, science, philosophy, and technology. Without logarithms (invented in the early 17th century by John Napier and improved by Henry Briggs), scientists would not have been able to calculate the movement of the planets, and mathematicians would not have been able to develop fractal geometry. The Wave Equation is one of the most important equations in physics, and is crucial for engineers studying the vibrations in vehicles and the response of buildings to earthquakes. And the equation at the heart of Information Theory, devised by Claude Shannon, is the basis of digital communication today.An approachable and informative guide to the equations upon which nearly every aspect of scientific and mathematical understanding depends, In Pursuit of the Unknown is also a reminder that equations have profoundly influenced our thinking and continue to make possible many of the advances that we take for granted.

    They are converted to metric units using realistic data to help students grasp what is feasible in engineering practice.

    Who has not wondered about how the human body works? Can a person drink too much water? How does gravity make things fall? From topics as varied as the Earth and atoms to sports and music, we all carry with us those questions we've always wanted answered but never knew whom to ask.Mysteries lurk in our bodies, our houses, the outdoors, in the sky above us, and the universe beyond us. Now, award-winning high school science teacher Larry Scheckel tackles 250 questions that help us to more clearly understand all of these mysteries. Scheckel perfected the art of explaining science topics not only as a science teacher for more than 38 years in his native Wisconsin, but also through writing a weekly column in his local paper, the "Tomah Journal," in which each week he'd field a question like those that are collected in this book.

    -Emest Hemingway In October 1984, the weak writing in a scientific report made national news. The report, which outlined safety procedures during a nuclear attack, advised industrial workers "to don heavy clothes and immerse themselves in a large body of water. " The logic behind this advice was sound: Water is a good absorber of heat, neutrons, and gamma rays. Unfortunately, the way the advice was worded was unclear. Was everyone supposed to be com- up for air? Be- pletely submerged? Was it safe to come sides being unclear, the writing conveyed the wrong im- pression to the public. The report came across as saying "go jump in a lake"-not the impression you want to give someone spending thousands of dollars to fund your re- search.

    They do this with little training, and often only their good intentions guide them. When Reasoning No Longer Works is the training manual these family caregivers have been searching for. Written by a Gerontologist with more than twenty years of experience, this reference gives the reader an easy to understand view of what dementia does to the brain, how it is diagnosed, and most importantly, how to deal with its effects. Bulleted lists clearly explain: • How to avoid a catastrophic reaction • Specific approaches for aggressive behavior • How to deal with disruptive behaviors • Ways to diminish wandering • What to do when a wanderer is missing • When to look for outside help You’ll also follow the story of Lou and Rose, a couple who share their lives with Alzheimer’s disease. Together, they find the answers to questions caregivers and victims are sometimes afraid to ask. (with foreword by Dr. Randall J. Bjork) "Sixteen years ago, my father, Charles, died as the result of AD. For many years to come, I knew that I had failed him. I wish I knew then what I read about now in When Reasoning No Longer Works. The stress of living with an Alzheimer’s patient in the family can be heart-wrenching, but this book provides hope and help.” — Jeanie M, daughter and caregiver

    Although almost every leader has heard of these works, very few have read them in depth and applied the lessons they contain to their own life. This is a huge oversight. Both books contain wisdom and advice which is applicable to almost any situation a leader finds they are in. Both books have a reputation for being dense and difficult to understand. This is due to the fact that both were written in other languages and for other time periods. It can be difficult to know exactly what Sun Tzu and Machiavelli intended to convey with their words - and even less how to take action on the ideas. This has all changed.For the first time ever, the ideas of The Prince and The Art of War have been combined, updated and presented in a way which is easy to understand in our modern era. Previously hard to interpret concepts have been clarified and shown to be as useful in our own era as they were in the one for which they were originally written. By reading and taking action on this book entitled Sun Tzu & Machiavelli Leadership Secrets by author Anthony D. Jensen, you give yourself the chance to become the most effective leader you can be. You will learn how to use timeless principles of leadership, psychology and power to achieve everything you set out to do. Both your private and professional lives will benefit immensely from understanding and applying the leadership secrets of Sun Tzu and Machiavelli.

    He was born to race —some of the fastest cars ever to tear up a speedway.  Carroll Shelby wasn’t born to run. He was born to race—some of the fastest cars ever to tear up a speedway. The exciting new feature film Ford v Ferrari--starring Matt Damon as Shelby and Christian Bale as fellow racer Ken Miles--immortalizes the small-town Texas boy who won the notorious Le Mans 24-hour endurance challenge, and changed the face of auto racing with the legendary Shelby Cobra. But there’s much more to his high-velocity, history-making story.A wizard behind the wheel, he was also a visionary designer of speed machines that ruled the racetrack and the road. While his GT40s racked up victories in the world’s most prestigious professional racing showdowns, his masterpiece, the Ford Cobra, gave Europe’s formidable Ferrari an American--style run for its money. If you’ve got a need for speed, strap in next to the man who put his foot down on the pedal, kept his eyes on the prize, and never looked back.

    In Turing’s Cathedral, George Dyson focuses on a small group of men and women, led by John von Neumann at the Institute for Advanced Study in Princeton, New Jersey, who built one of the first computers to realize Alan Turing’s vision of a Universal Machine. Their work would break the distinction between numbers that mean things and numbers that do things—and our universe would never be the same. Using five kilobytes of memory (the amount allocated to displaying the cursor on a computer desktop of today), they achieved unprecedented success in both weather prediction and nuclear weapons design, while tackling, in their spare time, problems ranging from the evolution of viruses to the evolution of stars. Dyson’s account, both historic and prophetic, sheds important new light on how the digital universe exploded in the aftermath of World War II. The proliferation of both codes and machines was paralleled by two historic developments: the decoding of self-replicating sequences in biology and the invention of the hydrogen bomb. It’s no coincidence that the most destructive and the most constructive of human inventions appeared at exactly the same time.  How did code take over the world? In retracing how Alan Turing’s one-dimensional model became John von Neumann’s two-dimensional implementation, Turing’s Cathedral offers a series of provocative suggestions as to where the digital universe, now fully three-dimensional, may be heading next.
