Numerical methods, including MATLAB and vector analysis, are also included to help students analyzesituations that they are likely to encounter in industry practice. Elements of Electromagnetics, Fifth Edition, is designed for introductory undergraduate courses in electromagnetics.

    Who was he, and what caused him to disappear? Was he simply a physicist, or also a spy and communist radical? A protege of Enrico Fermi, Pontecorvo was one of the most promising nuclear physicists in the world. He spent years hunting for the Higgs boson of his day -- the neutrino -- a nearly massless particle thought to be essential to the process of particle decay. His work on the Manhattan Project helped to usher in the nuclear age, and confirmed his reputation as a brilliant physicist. Why, then, would he disappear as he stood on the cusp of true greatness, perhaps even the Nobel Prize? In Half-Life, physicist and historian Frank Close offers a heretofore untold history of Pontecorvo's life, based on unprecedented access to Pontecorvo's friends and family and the Russian scientists with whom he would later work. Close takes a microscope to Pontecorvo's life, combining a thorough biography of one of the most important scientists of the twentieth century with the drama of Cold War espionage. With all the elements of a Cold War thriller -- classified atomic research, an infamous double agent, a possible kidnapping by Soviet operatives -- Half-Life is a history of nuclear physics at perhaps its most powerful: when it created the bomb. Physics at perhaps its most powerful: when it created the bomb.

    Naturalist. Warrior. President. There are so many sides to Theodore Roosevelt that it is easy to overlook one of his most enduring contributions to American public life: the use of fame to fuel his political career.In this concisely written, enlightening book, presidential historian Lewis L. Gould goes beyond the bully pulpit stereotypes to reveal how Roosevelt used his celebrity to change American politics. Based on research gleaned from the personal papers of Roosevelt and his contemporaries, TheodoreRoosevelt recaptures its subject's bold activism and irrepressible, larger-than-life personality. Beginning with his privileged childhood in New York City, the narrative traces his election to the New York Assembly, where he quickly rose through the ranks of the Republican Party. It is here that hefirst applied his shrewd ability to keep himself in the spotlight--a skill that served him well as commander of a volunteer regiment (dubbed Roosevelt's Rough Riders) in the Spanish-American War. Gould shows how Roosevelt rode a wave of popular acclaim at the war's end, assuming the governorshipof New York and serving as president from 1901 to 1909. While covering his major accomplishments as chief executive, including his successes as a trust-buster, labor mediator, and conservationist, Gould explains how fame both sustained and limited Roosevelt when he ran for president in 1912 andopposed Woodrow Wilson's policies during World War I.Theodore Roosevelt delivers the most insightful look yet at a pioneer of political theater--a man whose vigorous idealism as a champion of democracy serves as a counterpoint to the cynicism of today's political landscape. The book will coincide with the 100th anniversary of Roosevelt's third partyrun for the Progressive or Bull Moose Party.

    Joe – as he is affectionately known to millions of readers, listeners, viewers, and students – brings his magic formula to Doubleday Canada with Brain Fuel.As with Dr. Joe’s previous best-selling books, Brain Fuel informs and entertains on a wild assortment of science-based topics. But this is not "science trivia." If you are looking for serious scientific discussions, you’ll find them here. If you are looking for practical consumer information, that’s here too. If you are searching for ways to stimulate interest in science, look no further, Mom. And if you are simply wondering why the birth of Prince Leopold was so different from Queen Victoria's previous seven; or why an iron rod that went through a man's head is now on display in a museum in Boston; or why white chocolate has such a short shelf life; or why eggs terrified Alfred Hitchcock – and what all of this means for the rest of us, and why – then bingo.

    Now, in this provocative and powerfully argued book, he takes on the most controversial issue of our time—the war against the global network of terrorists that attacked us on 9/11.From the Trade Paperback edition.

    He manned the barricades against superstition and pseudoscience, and pressed for a scientifically literate populace years before science had been deemed worthy of common study. A friend of Charles Dickens and an inspiration to Thomas Edison, the deeply religious Faraday sought no financial gain from his discoveries, content to reveal God's presence through the design of nature. Faraday speaks to us today through the prose of his letters and journals. In The Electric Life of Michael Faraday, Alan Hirshfeld presents an intimate and memorable portrait of an icon of science, making Faraday's most significant discoveries about electricity and magnetism readily understandable, and immortalizing his momentous contributions to the modern world.

    Carroll at his very best.--Bill Bryson, author of The Body: A Guide for Occupants From acclaimed writer and biologist Sean B. Carroll, a rollicking, awe-inspiring story of the surprising power of chance in our lives and the worldWhy is the world the way it is? How did we get here? Does everything happen for a reason or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance. A Series of Fortunate Events tells the story of the awesome power of chance and how it is the surprising source of all the beauty and diversity in the living world.Like every other species, we humans are here by accident. But it is shocking just how many things--any of which might never have occurred--had to happen in certain ways for any of us to exist. From an extremely improbable asteroid impact, to the wild gyrations of the Ice Age, to invisible accidents in our parents' gonads, we are all here through an astonishing series of fortunate events. And chance continues to reign every day over the razor-thin line between our life and death.This is a relatively small book about a really big idea. It is also a spirited tale. Drawing inspiration from Monty Python, Kurt Vonnegut, and other great thinkers, and crafted by one of today's most accomplished science storytellers, A Series of Fortunate Events is an irresistibly entertaining and thought-provoking account of one of the most important but least appreciated facts of life.

    Robert Oppenheimer rode out his political persecution in the Director's mansion.
