His contributions to our current understanding of the universe include a number of novel ideas, two of which—eternal cosmic inflation and the quantum creation of the universe from nothing—have provided a scientific foundation for the possible existence of multiple universes.With this book—his first for the general reader—Vilenkin joins another select group: the handful of first-rank scientists who are equally adept at explaining their work to nonspecialists. With engaging, well-paced storytelling, a droll sense of humor, and a generous sprinkling of helpful cartoons, he conjures up a bizarre and fascinating new worldview that—to paraphrase Niels Bohr—just might be crazy enough to be true.

    But as an adult, when he most needs the irrefutable order and precision of science itself, Benito will learn that, despite its expansive beauty and power, it is no match for the unfathomable desires and pains of the human heart. Lightman is the acclaimed author of Einstein's Dreams.

    And from the ancients who plotted its path at Stonehenge to the modern scientists who unraveled the nuclear fusion reaction that turns mass into energy, humankind has sought to solve its mysteries. In this lively biography of the sun, Bob Berman ranges from its stellar birth to its spectacular future death with a focus on the wondrous and enthralling, and on the heartbreaking sacrifice, laughable errors, egotistical battles, and brilliant inspirations of the people who have tried to understand its power. What, exactly, are the ghostly streaks of light astronauts see-but can't photograph-when they're in space? And why is it impossible for two people to see the exact same rainbow? Why are scientists beginning to think that the sun is safer than sunscreen? And how does the fluctuation of sunspots-and its heartbeat-affect everything from satellite communications to wheat production across the globe? Peppered with mind-blowing facts and memorable anecdotes about spectral curiosities-the recently-discovered "second sun" that lurks beneath the solar surface, the eerie majesty of a total solar eclipse-The Sun's Heartbeat offers a robust and entertaining narrative of how the Sun has shaped humanity and our understanding of the universe around us.

    

    It provides a simple, thorough survey of elementary topics, starting with set theory and advancing to metric and topological spaces, connectedness, and compactness. 1975 edition.

    This edition retains the scope and emphasis that have made the book very successful while adding over twenty new numerical examples and over 550 new end-of-chapter problems.

    Written in a clear and accessible narrative, the 7th Edition focuses on fundamental principles and their applications to solving real circuit analysis problems, and devotes six chapters to examining electronic devices. With an eye-catching visual program and practical exercises, this book provides readers with the problem-solving experience they need in a style that makes complex material thoroughly understandable. For professionals with a career in electronics, engineering, technical sales, field service, industrial manufacturing, service shop repair, and/or technical writing.

    By replacing equations with diagrams, the book allows non-specialist readers to fully understand the concepts in relativity without the slow, painful progress so often associated with a complicated scientific subject. It allows readers not only to know how relativity works, but also to intuitively understand it.

    Uncle John and his loony lab partners will take you back to the Big Bang and forward to the distant future. You’ll see the science in everything around (and inside) you, and learn the truth about the most egregious science myths (such as—you can’t “sweat like a pig” because pigs don’t sweat). How many amazing facts await your visual cortex in these 494 pages made up of atoms (print version) or bits and bytes (e-book)? As Carl Sagan would have said, “Billions and Billions!” So put on your thinking cap and check out…Pluto deniedKitchen chemistryFootball gets physics-alPlanet Earth’s sudden hot flashesFood’s incredible journey…through youThe science of surfing, skating, and snowboardingHow they plugged the hole in the ozone layerHow “defenseless” animals stay aliveSci-fi that’s more fi than sciAncient astronomersKnow your cloudsAnd much, much more!

    It traces the history and cultural impact of the elements on humankind, and examines why people have long sought to identify thesubstances around them. The book includes chapters on particular elements such as gold, iron, and oxygen, showing how they shaped culture and technology. Looking beyond the Periodic Table, the author examines our relationship with matter, from the uncomplicated vision of the Greek philosophers, whobelieved there were four elements--earth, air, fire, and water--to the work of modern-day scientists in creating elements such as hassium and meitnerium. Packed with anecdotes, The Elements is a highly engaging and entertaining exploration of the fundamental question: what is the world made from?

    The Universe. Everything. The human race has always revealed an insatiable hunger to search "to infinity and beyond". In this truly mind-blowing book, partners in science Stuart Lowe and Chris North use cutting edge infographics to illuminate - in a new and unique way - the most amazing places and objects that modern science has laid bare. Featuring innovative, inspirational and original designs by leading authors in their field, COSMOS: THE INFOGRAPHIC BOOK OF SPACE delves into a truly international subject and will appeal to stargazers and space enthusiasts of all ages.Including the Big Bang itself, COSMOS: THE INFOGRAPHIC BOOK OF SPACE:Explores the secret lives of galaxies and starsExamines the thousand new planets now discovered beyond the Solar System, checking out their viability for alien lifeChronicles the incredible instruments and machines that are discovering the hidden secrets of the Universe, from 'telescopes' atop the highest mountains to robotic explorers on distant worlds...Investigates the astounding technology used by human and robotic explorers as they push out beyond the Moon to Mars - and on towards the stars...

    

    Despite this, he has remained inaccessible to most modern readers, indisputably great but undeniably remote. In this witty, engaging, and often moving examination of Newton's life, David Berlinski recovers the man behind the mathematical breakthroughs. The story carries the reader from Newton's unremarkable childhood to his awkward undergraduate days at Cambridge through the astonishing year in which, working alone, he laid the foundation for his system of the world, his Principia Mathematica, and to the subsequent monumental feuds that poisoned his soul and wearied his supporters. An edifying appreciation of Newton's greatest accomplishment, Newton's Gift is also a touching celebration of a transcendent man.
